Answer:

The correct option is D) 8+d=43

Step-by-step explanation:

Consider the provided equation.

$8 - (-d) = 43$

We need to find the another way to express the above equation.

Remove the parentheses and change the sign of subtraction to plus.

$8 +d = 43$

Thus, the another way to express the provided equation is $8 +d = 43$

Hence, the correct option is D) 8+d=43

Find the radius of a sphere with a volume of 972π cubic millimeters.

sesenic [268]

Answer:

The radius is 9 mm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3 where r is the radius

972 pi = 4/3 pi r^3

Divide each side by pi

972 = 4/3 r^3

Multiply each side by 3/4 to isolate r^3

3/4 * 972 = 4/3 * 3/4 r^3

729 = r^3

Take the cube root of each side

(729) ^ (1/3) = (r^3) ^ (1/3)

9 = r

The radius is 9 mm

What is the square root of 46?

Kazeer [188]

If you estimate
7 times 7=49 so the square root of 46 is less than 7
6 times 6= 36 so the square root of 46 is more than 6
so if you do it on a calculator the answer is 6.78
