Ksenya-84 [330]

Answer:

C- 15 cars.

Step-by-step explanation:

To do this, you will need to set up an equation as follows:

8x+15=6x+45

Then you will subtract 6x from each side. Then you will have this:

2x+15=45

Then you will subtract 15 from each side, and then you will have:

2x=30

Then you will divide each side by 2 and you will get 15. Hope this helped!

Circle A has center of (2, 8), and a radius of 2 and circle B has a center of (5, 4), and a radius of 10. What steps will help s

SVETLANKA909090 [29]

Answer:

D.Dilate circle A by a scale factor of 5.

Step-by-step explanation:

We are given that

The center of circle A is (2,8) and radius of circle A is 2.

The center of circle B is (5,4) and radius of circle B is 10.

We have to find the steps will help to show that circle A is similar to circle B.

When two circles are similar it means the size of circles can be same or different.Therefore, radius of circles will be same or different.

But, the radius of circles are different.

Dilation: It is a transformation in which obtained figure is similar to the original figure.

Shape remains same but the size of figures are different.

Ratio of corresponding sides of two figures=Scale factor

When a circle is dilated then,

Ratio of radius of circle obtained after dilation to the radius of original circle= Scale factor

Scale factor= $\frac{10}{2}=5$

Hence, option D is true.

2x + 3 > 13<br><br> Whats the answer plz help

Naily [24]

Answer:

In this case, you can simply treat the > sign like an = sign. The only time you would need to worry about is when multiplying or dividing by negative numbers.

2x + 3 > 13

2x + 3 - 3 > 13 - 3

2x > 10

2x / 2 > 10 / 2

x > 5

Estimate the rate at which the total personal income is rising in a metropolitan area. In 1999, the population of this area was

Natasha2012 [34]

Answer:

$X=\$1.64*10^9$

Step-by-step explanation:

From the question we are told that:

Population size $P=918000$

Rate of Population increase $\frac{dP}{dt}=9700$

Average annual income $I= \$34,549$

Rate of annual income increase $\frac{dI}{dt}=\$1300$

Generally the equation for Total Income is mathematically given by

$X=P \frac{dI}{dt}+I \frac{dP}{dt}$

$X=918000*1400+(9200*30593)$

$X=\$1.64*10^9$
