Subtract 8 from both sides
So you end up with x = -23

Solve for x; in order to do that you must subtract 8 from both sides so x is by itself; the answer is -23

You are planning on using circles to compare the populations of California 37,691,000, Texas 25,675,000, and New York 19,465,000

Aneli [31]

The areas of the circle will represent the population, so:
Area = πr²

5² : 19,465,000
C² : 37,691,000

California circle radius = 6.96 cm

For Texas:
5² : 19,465,000
T² : 25,675,000

Texas circle radius = 5.74 cm

If a/b = 2 /5, b/c = 3 /8, a/c =??

scoray [572]

Answer:

3/20

Step-by-step explanation:

By question it's given that ,

$\implies \dfrac{a}{b}=\dfrac{2}{5}$

$\implies \dfrac{b}{c}=\dfrac{3}{8}$

And we need to find out the value of a/c .For that Multiply both of them , we have ;

$\implies \dfrac{a}{b} \times\dfrac{b}{c}=\dfrac{2}{5}\times \dfrac{3}{8} \\\\\implies \dfrac{a}{c}= \dfrac{3}{20}$

Hence the required answer is 3/20 .

Step-by-step explanation:

Area of a trapezium = SOPS/2 × ph

Sops is the sum of 4+10 = 14

14/2 is 7. 7×4 = 28

A = 28cm²

Area = L×W

10×6= 60cm²

Answer:

A. 2564 cm^2

Step-by-step explanation:

There are two triangles (Which both are the same) and three different rectangles.

1. Let's solve the area of the triangles first!

Formula: bh(1/2)

10(26)(1/2)

130

2. Now, let's multiply by 2 since there's two of them:

130(2) = 260

3. So, we got 260. Let's find the area of the three rectangles!

Formula: bh

Rectangle A: 28(36) = 1008

Rectangle B: 10(36) = 360

Rectangle C: 26(36) = 936

4. Add the area of the triangles and the rectangles!

260 + 1008 + 360 + 936 = 2564

So the surface area is 2564 cm^2

Hope this helps! <3
