Answer:

Step-by-step explanation:

Circumference = 2 * pi * r

Circle A / Circle B = 2 * pi * 8 / 2 * pi * 2

You need to take note of the right side. The 2s cancel and so does pi

Circle A/ Circle B = 8/2

Circle A / Circle B = 4/1 = 4

Which is D

Answer:

1/4

Step-by-step explanation:

For the first circle 2 x 2in = 4 to find diameter

4 x 3.14 = 12.56

6in x 2 = 12

12 x 3.14 = 37.68

simplify

12.56/37.68

6.28/18.84

3.14/9.42

So the answer is 1/4 since 3.14 x 2 = 6.28

Also since the radius is 2 times longer

Answer:

2x^3 + x^2 + x

Step-by-step explanation:

For ...

$a^{b}=x$

The expression ...

$2a^{3b}+a^{2b}+a^{b}$

can be rewritten as ...

$2(a^{b})^3+(a^b)^2+(a^b)=2x^3+x^2+x$

The Rectangular rug has side lengths of 3 and 4 feet. What is the length of the diagonal?

lesya [120]

the formula to find the diagonal would be

a^2+b^2=c^2

3^2+4^2= 9+16=25

the square root of 25 is 5

5^2=25

so your diagonal is 5 ft

Which one?????? i need help

borishaifa [10]

<h3>Given</h3>

x + 2 ≥ 6

the graph for the solution

<h3>Solution</h3>

We can solve for x by subtacting 2 from both sides of the inequality.

... x + 2 -2 ≥ 6 -2

... x ≥ 4 . . . . . . . . . . simplify

The answer is read, "x is greater than or equal to 4." This means the solution is those real numbers that are to the right of 4 on the number line, and including 4 on the number line. Numbers to the left of 4 are <em>not included</em>. The inclusion of the number 4 is shown by putting a solid dot there (not an open circle).

The appropriate choice is the 3rd one.
