<span> 144 </span><span>square inches are needed to cover a square foot. We know this because one (normal) foot is 12 inches, and to make it a square foot we simply multiply a side by itself, we take the number 12 and go: 12x12= 144

Therefore, 144 is how many square inches are needed to cover a square foot

Hope this helps!</span>

A sphere of radius 2x m has an area of 152.4 m2 and a volume of 360.9 m3. How much will the area and volume of another sphere

VladimirAG [237]

Answer:

$V = 1218.0375m^{3}$

$A = 342.9m^{2}$

Step-by-step explanation:

Area:

$A =$ π $r^{2}$

$152.4 =$ π $(2x)^{2}$ *Square 2x*

$152.4 =$ π $4x^{2}$ *Divide by π*

$48.510 = 4x^{2}$ *Divide by 4*

$12.128 = x^{2}$ *Square root*

$\sqrt{12.128} = x$ *Solve*

x ≈ 3.482

Now take the same equation but replace 2x with 3x

$A =$ π $r^{2}\\$

Now replace x with 3.482 and solve for area.

$A = 342.9m^{2\\}$

Volume:

$V = \frac{4}{3}$ π $r^{3}$ *Insert variables*

$360.9 = \frac{4}{3}$ π $(2x)^{3}$ *Cube 2x*

$360.9 = \frac{4}{3}$ π $(8x^{3})$ *Multiply $\frac{3}{4}$ on both sides*

$270.675 =$ π $(8x^{3})$ *Divide by π*

$86.159 = 8x^{3}$ *Divide by 8*

$10.770 = x^{3}$ *Cube root*

$\sqrt[3]{10.770} = x$ *Solve*

x ≈ 2.208

Now take the same equation but replace 2x with 3x

$V = \frac{4}{3}$ π $(3x)^{3}$

Now replace x with 2.208 and solve for volume.

$V = 1218.0375m^{3}$

DESCRIBE IN WORDS THE TRANSLATION OF x represented by the translation rule <-6,8> (X) A. 6 units to the right and 8 units

Valentin [98]

Given:

Translation of x represented by the translation rule <-6,8>.

To find:

The correct statement for the given rule of translation.

Solution:

Rule of translation is <-6,8>.

Here, x-coordinate represents horizontal shift and y-coordinate represents vertical shift.

x-coordinate is -6, which is negative. So, the figure translated 6 units left.

y-coordinate is 8, which is positive. So, the figure translated 8 units up.

Thus, translation in words is defined as "6 units to the left and 8 units up".

Therefore, the correct option is B.

I am thinking of a number. If you add 3 to the number and then multiply the sum by four, you end up with 48. What is my number?

kap26 [50]

Answer:

9

Step-by-step explanation:

48 / 4 = 12

12 - 3 = 9

Check Work

9 + 3 = 12

12 * 4 = 48
