What is the value of x?
Enter your answer in the box.
Two intersecting lines. The angle formed at the top is labeled 3 x plus 50 degrees. The angle formed at the bottom directly opposite it is labeled 6 x minus 10 degrees.
Answers
We know that the two angles are opposite and therefore are equal, so we can set them equal to each other and solve for x:
3x + 50 = 6x - 10
Adding 10 to both sides, we get:
3x + 60 = 6x
Subtracting 3x from both sides, we get:
60 = 3x
Dividing both sides by 3, we get:
x = 20
Therefore, the value of x is 20.

Find the slope of each line
Answers
5 up over 4 left
-5/4 is your slope
Answer: The slope is -5/4.
Step-by-step explanation: The slope of a line refers to its direction and steepness. The slope can be expressed as a fraction that is commonly refered to as rise over run. In order to find the slope of a line, you need to find two coordinates on the line and use the "rise over run" method. The numerator (rise) is how many units up or down while the denominator (run) is how many units left or right. There are two given points on this specific line. To get from one to the other, you must go down 5 units and to the right 4 units; therefore, the slope, or rise over run, is -5/4.
Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.
For a similar problem about this, please click the link below:
https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.

Mr. Aamodt bought a new lawn tractor for $3,350.
a. The state sales tax on the lawn tractor purchase will be 6.5%. How much state sales tax will Mr. Aamodt pay on the tractor? (2 points)
b. Mr. Aamodt has applied for a 2‐year loan at the bank for $3,350 to pay for the new lawn tractor. The bank will charge him 8.4% simple interest on the loan. What amount of interest will Mr. Aamodt pay on the loan? (2 points)
c. What is the total cost of Mr. Aamodt’s new lawn tractor, including the purchase price, the loan interest, and the sales tax? (2 points)
Answers
Answer:
A) 217.75 sales tax
B)281.40 he will pay on the loan
C)$3849.15 he will pay including total cost, interest, and tax
Step-by-step explanation:
A)
To find sales tax, multiply the price by its percentage. 6.5% in decimal is 0.065. 3350x0.065=217.75 for its sales tax.
B)
This is the same for loan.
3350x0.084=281.40 he will pay for loan.
C)
Now add it all up. 3350+217.75+281.40=3849.15
Answer:
The correct answers are:
a. $217.75!
b. $281.40!
c. $3,849.15!
Step-by-step explanation:
a. Find the sales tax by multiplying the price by its percentage (6.5%, 0.065 in decimal form)
3,350 x 0.065=217.75
so the sales tax is $217.75
b. This is the same as finding tax. Find the loan by multiplying the original price by the percentage (8.4%, 0.084 in decimal form).
3,350 x 0.084 = 281.40
so the loan is $281.40
c. This time, sum the original price with both the loan and sales tax.
3,350 + 217.75+ 281.40= 3849.15
so the total cost for the new tractor is $3,849.15
So there you have it. You have your answers right here. Hope this helps! Be sure to mark this as brainliest!

When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
5y-8x+3
——————— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
5y-8x+3 = 0
Equation of a Straight Line
5.2 Solve 5y-8x+3 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5y-8x+3 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/5 so this line "cuts" the y axis at y=-0.60000
y-intercept = -3/5 = -0.60000
Calculate the X-Intercept :
When y = 0 the value of x is 3/8 Our line therefore "cuts" the x axis at x= 0.37500
x-intercept = 3/8 = 0.37500
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -0.600 and for x=2.000, the value of y is 2.600. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 2.600 - (-0.600) = 3.200 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / R

The slope of the line is ___ and the y-intercept is ___. The ___ represents the number of postcards when she began collecting and the ___ represents the number of postcards added each vacation.
Answers
Answer:
The slope of the line is 8 and the y-intercept is 20. The y-intercept represents the number of postcards when she began collecting and the slope of the line represents the number of postcards added each vacation.
Step-by-step explanation:
In order to solve this equation, it is important to recall slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept. Now, let's look at the equation given and compare it to slope-intercept form.
y = 8x + 20y = mx + bWe can conclude that 8 is the slope of the line due to the fact that it has replaced m and we can also conclude that 20 is the y-intercept due to the fact that it has replaced b. Furthermore, we know from the description provided that Jacquie began with 20 postcards, and since we now know that these 20 postcards are the y-intercept, we can fill that in as our answer. This same logic can be applied with the 8 additional postcards added each vacation since we now know it is the slope of the equation.

Answer:
5.906 x 10^9
Step-by-step explanation:
(6.25 x 10^9) − (3.44 x 10^8).
step 1: make the exponents have common value
Move decimal point of 3.44 to the left once and add 1 to it's exponents.
that is 3.44 x10^8 becomes 0.344 x 10^9
= 6.25 x 10^9 - 3.44 x 10^8
= 6.25 x 10^9 - 0.344 x 10^9
step 2: bring out the common factor 10^9 since the exponents are the same.
Also, subtract the decimal numbers.
= (6.25 -0.344) 10^9
6.25 - 0.344 = 5.906
Therefore, the result is 5.906 x 10^9.
