A. 3 times 10^4
90000000 divided by 3000 is 30000 which happens to be equal to 3 times 10^4

If you want to learn how to do this just take your whole number ex: 3 and put 10^6 and you will have 3 followed by 6 zeros. The ^ is just how many zeros will follow your whole number at first.

ARE YOU GOOD AT GEOMETRY?? WILLING TO HELP SOMEONE OUT?? NEED EASY POINTS AND BRAINLIEST?? COME RIGHT THIS WAY ALL HELP IS APPRE
BlackZzzverrR [31]

Answer:

C: (-8,3) R:5

Step-by-step explanation:

The equation of a circle can be written as:

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center, and r is the radius

We have the equation:

(x+8)^2+(y-3)^2=25

Center:

The center is (-8,3)

(x+8)^2--> (x-h)^2

Therefore the x coordinate of the center is -8

(y-3)^2-->(y-k)^2

Therefore the y coordinate of the center is 3

Radius

r^2=25

Take the square root of both sides

\sqrt{r^2}=\sqrt{25}

r=5

(50 POINTS AND BRAINLIEST TO BEST)
Nana76 [90]

a) Cube area = 6a^2

a = 6(5.25)^2

5.25 * 5.25 = 27.5625 * 6 = 165.375

Rounded, thats 165.38

b) Rectangular prism area = 2(wl + hl + hw)

Lets say l = 6.8, w = 8.2, h = 10

It equals about 441.52

In parallelogram UVWX, U = 9x+15 and V = 6x+15. find W and X.​
AysviL [449]

Answer:

W = 9x + 15     X = 6x + 15

Step-by-step explanation:

Given

Shape: Parallelogram

U = 9x + 15

V = 6x + 15

Required

Determine W and X

Opposite sides of a parallelogram are equal.

So:

U =W and V = X

By substituting values of V and U in the above expressions, we have:

9x + 15 = W

W = 9x + 15

6x + 15 = X

X = 6x + 15
