Using the ruler postulate, find the distance between –9 and 2.

Answers

Answer 1

Answer:

11 units

Step-by-step explanation:

According to ruler postulate, if there are two points A with coordinate a

and point B with coordinate b, \

then distance ab is given by subtracting coordinate in any order i.e it can be (a-b) or (b-a) and then take the absolute value value of it.

mathematically it can be represented as

AB = |a-b| or |b-a|

_________________________________________

in the given problem points are -9 and 2

thus distance

distance between –9 and 2  = |-9 -2| = |-11|  = 11

absolute value of -11 is 11

alternatively, distance can be calculated as

distance between –9 and 2  = |2 -(-9) | = |2 + 9 | = |-11|  = 11

Firstly, brainly allows 1 question per question. So do not try this again.

Lets make the fractions all like terms.

242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.

1. 51  1/4.

2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.

3. 36/5=72/10.      72/10 - 37/10 = 35/10. As a mixed it is 3 1/2

4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.

70/6 - 51/6 = 19/6. 3 1/6.

Dotted line:

we need to find the length of the dotted line in order to be able to calculate the area of the rectangle

radius = 8 in

diameter (dotted line)

               = 8 x 2

               = 16 in  

(radius is half the diameter so now you know the length of the dotted line is 16 in - this answer is for the rectangle)

Area of the rectangle

A = L x W

using the 16 we found to calculate the area of the rectangle

                A = 23 x 16

                A = 368 in

Area of semi-circle:

Now to calculate the area of the semi-circle

A = π r² ÷ 2

             A = π 8² ÷ 2

                 = 100.48

Adding the area of the rectangle and semi-circle together:

               = 100.48 + 368

               = 468.48

        1dp = 468.5

y is inversely proportional to d²
When d = 10, y = 4
d is directly proportional to x²
When x = 2, d = 24
Find a formula for y in terms of x.
Give your answer in its simplest form.

Answers

Answer:

y = 100 / (9x⁴)

Step-by-step explanation:

y is inversely proportional to d²

y = k/d²

When d = 10, y = 4:

4 = k/10² k = 400

y is:

y = 400/d²

d is directly proportional to x²

d = mx²

When x = 2, d = 24

24 = m*2²m = 24/4m = 6

d is:

d = 6x²

Find a formula for y in terms of x:

y = 400 / d² = 400 / (6x²)² = 400 / (36x⁴) = 100 / (9x⁴)

The mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12

To find the mean deviation of the number of pets, the following steps would be taken:

Find the mean, which is sum of each frequency and score (fx) divided by the total number of pets. \(\mathbf{(\frac{\sum fx}{n} )}\)Subtract the mean from each score, \(\mathbf{( x - \bar x)}\)Sum the deviations together and divide by total number of pets.The formula for the mean deviation is given as: \(\mathbf{\frac{\sum f* |x - \bar x|}{n} }\)

Mean deviation as solved in the table attached in the image below would be:

Answers

The answers is: 33

33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

Step-by-step explanation:

Given:

A scuba diver is 15.5 feet below the surface of the water.

The diver continues to swim downward at a rate of 2.5 feet per second.

Now, to find the integer represents her location relative to the surface after 7 seconds.

And to find how far does the diver have to go to return to the surface.

So, to get the integer represents her location relative to the surface after 7 seconds.

Initial depth = 15.5 feet.

Distance traveled down = 7 × 2.5 = 17.5 feet.

Final depth of water surface = Initial depth + Distance traveled down.

Final depth of water surface = 15.5 feet + 17.5 feet.

Final depth of water surface = 33 feet.

Thus, 33 is the integer represents her location relative to the surface after 7 seconds.

Now, to get how far does the diver have to go to return to the surface:

As, the diver goes to 33 feet down to the surface.

Thus, the diver to return she have to go through the same distance.

So, to return to the surface she need to go to 33 feet far.

Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

33! hope this helped

HELP PLEASE 20 POINTS The graph shows the prices of different numbers of bushels of corn at a store in

Answers

Answer:

Part A: 8

Part B: $1

Step-by-step explanation:

Part A:

We know that 3 bushels is $24, and that rate remains constant, as the graph has a straight line.

Divide both sides by 3 to get 1 bushel = $8.

We can also double check with the other values: 48/6=$8 per bushel, 72/9=$8 per bushel, and so on.

The rate of change is the slope of a line (how much one value changes when the other value does). In this equation, the equation of the line is y=8x, so the slope is 8. Therefore, the rate of change is 8.

Part B:

In the previous year, each bushel of corn was 21/3, 42/6, etc., or $7 a bushel. This year, it is $8, so $8-$7=$1

Therefore, the price has increased by $1 this year.

Answe

Step-by-step explanation:  Part A:

a

For this problem, I would find the rate of change by finding the slope, which is the change in y over the change of x(y2-y1/x2-x1). In this case, for the current year, it would be 24(48-24) (change in y's) divided 3 (6-3)(change in x's), which comes out to 6. Hence, the rate of change for the current year is 6.

Part B:

Using the same method, the rate of change for the previous year would be 7. I found it by using the same equation. It would (42-21=21)(change in y's) / (6-3=3)(change in x's). 21/3 =7. Hence, for the previous year, the rate of change is 7.So the difference between the previous and current year is $1 (7-6).

Step-by-step explanation:

First, I'm going to work out the hourly wages for the 2 weeks.

$8 x 70hours = $560

(8 x 7 = 56 x 10 = 560)

Next, work out the commision.

10% of $1612

1612 ÷ 10 = 161.2

Finally, add together both the hourly wages and commision.

161.2 + 560 = 721.2

Round it down to a whole number.

721 , Add on the dollar sign.
