Answer:

80.7 inches

Step-by-step explanation:

circumference = 2 * pi * r

2 * pi * r = 507 inches

r = (507 inches)/(2 * pi)

r = (507 inches)/(2 * 3.14159)

r = (507 inches)/(6.2832)

r = 80.7 inches

PLEASE HELP Find the product. (a²b³)⁴​
cluponka [151]

Answer:

a^8b^{12}

Step-by-step explanation:

when you raise an exponent to a power you multiply

Also since the terms inside the parenthesis are multiplied and not added, you don't have to worry about expanding it

(a^2b^3)^4 = a^{2*4}b^{3*4}=a^8b^{12}

Evaluate 5+ (-11) - (-11)
SOVA2 [1]

Answer:

5

Step-by-step explanation:

To solve a problem with negatives, we use the following rule.

If it is like

x+(-y), it is equivalent to x-y

If the equation is like

(-x)-(-y), it is equivalent to (-x)+y

So,

5+(-11)=5-11=-6

(-6)-(-11)=(-6)+11=5

Your answer is 5.

The sum of two numbers is -47 the difference is -39 find the numbers
mash [69]

Answer:

x = -43

y = -4

Step-by-step explanation:

In this question, you will have to find the value of x in terms of y using one of the equations and substituting the value in the other equation or vice versa.

Let's assume the numbers x and y, now we write the expressions.

x + y = -47

x - y = -39

Take the second equation and find x.

<u>Calculations:</u>

x - y = -39 (Add y on both sides)

x = -39 + y

Now that you got the value of x in terms of y, we can substitute.

<u>Calculations:</u>

(-39 + y ) + y = -47

2y - 39 = -47

2y = -8

y = -8/2 = -4

y = -4

Now that we got y, we can substitute that value in any of the equations to find x.

x - 4 = -47 or x + 4 = -39

x = -43
