To the nearest whole number, what is the surface area of a sphere with a volume of 140 cm³?

1 answer:

6 0

The answer to this question is B. 130cm^2.

Using the volume formula for a sphere (V = (4/3)πr^3) you can plug in the values that we know to find the radius to be around 3.22117 cm. You can then use the area of a sphere formula (A = 4πr^2) to find the area. Hope this helps :)

A rectangle has a width of 46 centimeters and a perimeter of 204 centimeters. What is the rectangle’s length?

Vanyuwa [196]

Answer:

Length = 56

Step-by-step explanation:

Perimeter = Length + Length + Width + Width

Perimeter = 2L + 2W

2L + 2W = 204

2L + 2(46) = 204

2L + 92 = 204

Subtract 92 from both sides

2L = 112

Divide both sides by 2

L = 56

Length = 56

Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that?

Jobisdone [24]

Answer:

$y = \frac{3}{2}x - 3$

$y = \frac{1}{8} x - \frac{7}{8}$

Step-by-step explanation:

The given system is

3x-2y=6

0.4(20y+15)=x

The slope intercept form is y=mx+c.

For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

$y = \frac{3}{2}x - 3$

For 0.4(20y+15)=x, we expand to get:

$8y + 7 = x$

$8y= x - 7$

Divide through by 8

$y = \frac{1}{8}x - \frac{7}{8}$

Therefore the system in slope-intercept form is:

$y = \frac{3}{2}x - 3$

$y = \frac{1}{8}x - \frac{7}{8}$
