Kim's softball team was playing in the championship game. When there were 444 innings left, the team was losing by a score of 171717 to 666 runs. In the last 444 innings, her team scored the same number of runs per inning, and the other team did not score any more runs. Kim's team won with the most runs.
Write an inequality to determine the number of runs per inning, ppp, Kim's team could have scored.
Find the minimum whole number of runs per inning Kim's team could have scored.
The inequality to determine the number of runs per inning, p Kim's team could have scored is; 4r + 6 > 17
How to write an Inequality?
Let r represent the number of runs per inning. Thus for 4 innings, we have 4r.
The team already has 6 runs. Now add the additional runs to this to get;
4r + 6
The team wants to score more than the other team, this means they need more than 17 and so the inequality required is;
4r + 6 > 17
Subtract 6 from each side to get;
4r + 6 - 6 > 17 - 6
4r > 11
Divide both sides by 4 to get:
r > 2.75
Approximating to a whole number gives;
r > 3

-1 2/3 - -5/6 adding and subtracting rational numbers
By converting -1 2/3 to an improper fraction, we get -5/3. To add these fractions, we need to find a common denominator, which is 6. Adding the fractions gives us 5/6. Therefore, -1 2/3 - (-5/6) is equal to 5/6.
To perform the addition and subtraction of rational numbers, we start by converting -1 2/3 to an improper fraction. We multiply the whole number (-1) by the denominator of the fraction (3), which gives us -3. Adding the result to the numerator (2) gives us -3 + 2 = -1. So, -1 2/3 can be represented as -5/3.
Next, we rewrite the expression as -5/3 - (-5/6). When we subtract a negative number, it is equivalent to adding the positive value. So, -(-5/6) becomes +5/6.
To add fractions, we need a common denominator. In this case, the common denominator is 6. We multiply the numerator and denominator of -5/3 by 2 to get -10/6. Therefore, the expression becomes -10/6 + 5/6.Now that the fractions have the same denominator, we can add the numerators. -10/6 + 5/6 equals -5/6.
Hence, the final result of -1 2/3 - (-5/6) is 5/6.

Winning lottery 5 times most likely, guessing 64-bit key, 128-bit key, hit by lightening.
What is probability ?
Probability is a measure of the likelihood of an event occurring. It is typically expressed as a decimal or fraction between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain.
1) Being hit by lightning this year (probability is 1/105) - The probability is the lowest because the odds of being hit by lightning in a given year are relatively low.
2) Guessing a 128-bit key on the first try - The probability of guessing a 128-bit key on the first try is very low because of the large number of possible key combinations.
3) Guessing a 64-bit key on the first try - The probability of guessing a 64-bit key on the first try is lower than guessing a 128-bit key, but still relatively low because of the large number of possible key combinations.
4) Winning a lottery with 1 million (106) contestants five times in a row (the probability is (1/106)5) - The probability of winning a lottery with such large number of contestants is relatively low, but it is still much higher than the first three events.
So the order is:
1) Being hit by lightning this year
2) Guessing a 128-bit key on the first try
3) Guessing a 64-bit key on the first try
4) Winning a lottery with 1 million contestants five times in a row,

A salesperson earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns $4,800. A person selling 8 cars and 1 truck earns $4,600. How much does a salesperson earn for selling 2 cars and 3 trucks?
Answer:
$2800
Step-by-step explanation:
let x represent the amount earned on the sale of a car
let y represent the amount earned on the sale of a truck
6x+3y=4800-eqn 1
8x+y=4600-eqn 2
Make y the subject of eqn 2
y=4600-8x
Plug y=4600-8x into eqn 1
6x+3(4600-8x)=4800
6x+13800-24x=4800
13800-4800=18x
18x=9000
x=9000/18=500
Now plug the value of x into eqn 2
8(500)+y=4600
4000+y=4600
y=600
So the amount earned on the sale of a car is $500 and $600 on the sale of a truck
Therefore,if 2cars and 3trucks are sold then
2($500)+3($600)
$1000+$1800
=$2800

PLEASE MARK AS BRAINLIEST9. The diameter of the Earth is 7899.83 miles from the North Pole to the South Pole and 7926.41 miles from opposite points at the equator.
a. Find the approximate surface area of Earth using each measure.
b. About 75% of Earth's surface is covered by water. Find the surface area of water on Earth, using the diameter of the Earth is 7926.41 miles from opposite points at the equator.
Answer:
We could think of the Earth as a sphere, where the diameter of this sphere will the mean diameter between the measure from the North pole to the Soth pole and the measure from opposite points of the equator.
Remember that the mean between two numbers A and B is:
Mean = (A + B)/2
In this case, the mean diameter will be:
D = (7,899.83mi + 7,926.41mi)/2 = 7,913.115 mi
And we know that the surface of a sphere of diameter D is:
S = 4*pi*(D/2)^2
Where pi = 3.14
Then the surface of the Earth will be something like:
S = 4*3.14*(7,913.115mi/2)^2 = 196,618,601.47 mi^2
b) We know that 75% of the Earth's surface is water, now we will use the diameter 7,926.41 mi to compute the surface.
First, the total surface of the Earth will be:
S = 4*3.14*(7,926.41mi/2)^2 = 197,279,843.03 mi^2
And 75% of this is water, then the total water surface is 0.75 times that area, this is:
water surface = 0.75*197,279,843.03 mi^2 = 147,959,882.27 mi^2

An angle can be named by any of ...
its vertexan angle designator in an unambiguous place (usually inside, near the vertex)three points, with the vertex listed in the middleNote that angle ABC consisting of rays BA and BC sharing end point B can also be named angle CBA.
__
1. The rays share end point J. That is the vertex of the angle. The rays are named using the end point first, so the rays in this diagram are JH and JK.
The vertex is J; the sides are JH and JK.
__
5. We note there is an angle designator inside near the vertex, point M. That designator can be used to name the angle: angle 3.
There are only two rays that meet at vertex M, so the angle can also be named by naming the vertex: angle M.
The angle can also be named by naming an point on each ray, with the vertex in the middle: angle LMN or angle NML.
The four ways to name this angle are: angle 3, angle M, angle LMN, angle NML.
__
10. All of the angles with numeric designators have V as a vertex. Those angles are angle 3, angle 1, angle 6.
In this case, we cannot use V to name an angle, because many angles have vertex V. That name would be ambiguous, not referring to a specific angle.
The other angles that have V as a vertex can be named by naming their rays. There are 4 rays that meet at vertex V. Any two will identify an angle. There are 4·3 = 12 permutations of 4 rays taken 2 at a time. For example, if we choose to use rays VJ and VK as the two rays of our angle, we can name it two ways: JVK or KVJ. (This particular angle is also angle 1.)
So, the angles that have V as a vertex are ...
angles HVJ, HVK, HVL, JVK, JVL, KVL, JVH, KVH, LVH, KVJ, LVJ, LVK

Expedition Everest, a major thrill ride at Walt Disney World, often has a demand of over 3,000 riders an hour causing long waiting times for guests wishing to ride. The attraction averages 1,800 riders an hour. The roller coaster has a design capacity of 2,050 riders an hour and an effective capacity of 1,900 riders an hour.
a. What is the efficiency of Expedition Everest?
b. What is the utilization of Expedition Everest?
c. Is the operation overcapacity or undercapacity?
a. The efficiency of Expedition Everest is approximately 87.8%.
b. The utilization of Expedition Everest is approximately 94.7%.
c. The demand is greater than the effective capacity, the operation is considered overcapacity. This means that the ride cannot accommodate all the riders who wish to ride, resulting in long waiting times for guests.
To calculate the efficiency and utilization of Expedition Everest, we need to compare the actual number of riders with the design capacity and effective capacity.
Given:
Demand = 3,000 riders/hour
Average riders = 1,800 riders/hour
Design capacity = 2,050 riders/hour
Effective capacity = 1,900 riders/hour
a. Efficiency:
Efficiency is calculated as the average riders divided by the design capacity, multiplied by 100%.
Efficiency = (Average riders / Design capacity) * 100%
= (1,800 / 2,050) * 100%
≈ 87.8%
Therefore, the efficiency of Expedition Everest is approximately 87.8%.
b. Utilization:
Utilization is calculated as the average riders divided by the effective capacity, multiplied by 100%.
Utilization = (Average riders / Effective capacity) * 100%
= (1,800 / 1,900) * 100%
≈ 94.7%
Therefore, the utilization of Expedition Everest is approximately 94.7%.
c. Capacity Analysis:
To determine if the operation is overcapacity or undercapacity, we compare the demand with the effective capacity.
Demand > Effective capacity
3,000 > 1,900
Since the demand is greater than the effective capacity, the operation is considered overcapacity. This means that the ride cannot accommodate all the riders who wish to ride, resulting in long waiting times for guests.

During a power outage, Mason burns candles for light. Each candle was initially 12 inches long. He wants to know how long they will last. The candles burn at a constant rate, and Mason measures them twice and records their height each time in the table:
Number of hours the candle has been lit = 1 1/2 , 4 1/2
Length of candle = 11 1/4 in , 9 3/4 in
Answers: 6 hrs, 9 hrs, 12 hrs, 24 hrs, 48 hrs
The number of hours each 12 inches candle will last, found using the linear equation obtained from Mason's measurement is 24 hours
What is a linear function?A linear function is a relationship between two variables, that when plotted produces a straight line graph.
The initial length of the candle = 12 inches
Number of hours the candle has been lit, 1 1/2 hour = 1.5 hour
4 1/2 hour = 4.5 hour
11 1/4 inches = 11.25 inches
9 3/4 inches = 9.75 inches
The ordered pair of the height of the candle and height are;
(1.5, 11.25), (4.5, 9.75)
The slope of the line that represent the height as a function of time is therefore;
(9.75 - 11.25)/(4.5 - 1.5) = -0.5
The equation of the line in point-slope form is therefore;
y - 11.25 = (-0.5) × (x - 1.5) = -0.5·x + 0.75
y - 11.25 = -0.5·x + 0.75
y = -0.5·x + 0.75 + 11.25
y = -0.5·x + 12
The above equation produces the height y after a time x
When the candle finishes, the height is zero, therefore;
y = 0 = -0.5·x + 12
0.5·x = 12
x = 12 ÷ 0.5 = 24

There are 8 red, 4 green, and 6 blue point on a circle. All the points are distinct. Find the number of triangles with vertices of three different colors.
To find the number of triangles with vertices of three different colors, we need to consider the combinations of colors we can choose from the given set of points.
We have 8 red points, 4 green points, and 6 blue points. To form a triangle with vertices of three different colors, we need to choose one point from each color group.
First, let's choose one red point. We have 8 options for this.
Next, let's choose one green point. We have 4 options for this.
Finally, let's choose one blue point. We have 6 options for this.
To determine the total number of triangles, we need to multiply the number of options for each color:
Total number of triangles = Number of options for red points × Number of options for green points × Number of options for blue points
= 8 × 4 × 6
= 192
Therefore, there are 192 triangles with vertices of three different colors.
It's worth noting that the order in which we choose the points does not matter because we are counting the number of distinct triangles. So, we are not considering permutations but rather combinations of colors.

the area of the triangle formed by the x and y intercepts of the parabola y=0.5(x-3)(x+k) is equal to 1.5 square units. find all possible values of k.
The possible values of k are -0.56, -3.56, -2 and -1.
Find all possible values of k ?We have the equation of the parabola, y = 0.5 (x- 3 ) ( x+ k)
Substituting x=0, we get that i.e. y =0.5 * (-3) * k -1.5k
So, the y-intercept is (0,-1.5k).
Thus, the height of the triangle becomes |-1.5k| = 1.5k
Again, substituting y=0, 0 = 0.5 (x-3) (x+k) i.e. i.e. x0=(x-3) (x+k)=3 and x=-k
So, the x-intercepts are (3,0) and (-k,0).
Thus, the base of the triangle is 3+k if k>-3 or -3-k if k<-3.
As, area of a triangle = 1/2 * (base )* (height )
Substituting the values, we get,
1.5=1/2 *(3+k)*(1.5k)
i.e.3= 4.5 k + 1.5k ²
i.e. k = -0.56 and k = -3.56
or
1.5=1/2* (-3-k )*(1.5k)
i.e.
3 = -4.5 k - 1.5²
i.e. k = -2 and k = -1.
