Answer:

≈ 1.3 inches

Step-by-step explanation:

Given that:

  • Sphere A = 30 cubic inches
  • Sphere B = 10 cubic inches

As we know, the formula to find the volume of a sphere is;

V = π\frac{4}{3} r^{3}

So we have:

  • Sphere A = 30 cubic inches

<=> π\frac{4}{3} r^{3}  = 30

<=>r^{3}  = 90/4π

<=> r ≈ 4.13

  • Sphere B = 10 cubic inches

<=> π\frac{4}{3} r^{3}  = 10

<=> r^{3} = 30/4π  

<=>  r ≈ 2.86

So the  different between the radius of sphere A and B is:

= 4.13 - 2.86

= 1.27

≈ 1.3 inches

Marizza181 [45]

Answer:

She sneezed for 138.286 weeks in a row. You need days of week to create a proper conversion.

Step-by-step explanation:

There are 7 days in a week. There are 978 days shown.

You can depict it as this:

978 = 7x; x is the amount of weeks.

Divide both sides by 7

138.285714 = x

Round to three decimals

x = 138.286

Solving an Absolute Value Equation
Andre45 [30]

Answer:

Solution set = {-12, 12}

Step-by-step explanation:

Start by dividing both sides of the given equation by negative one, to get rid of the negative signs on both sides:

-\,|-x|=-\,12\\|-x|=12

Now we consider the two possible cases:

1) The expression inside the absolute value symbol is a positive number, then :

|-x|=-x\\

and replacing it in the equation, this becomes:

|-x|=12\\-x=12\\x=-12

which is our first answer.

2) The expression inside the absolute value symbol is a negative number, then :

|-x|=x\\

and replacing it in the equation, this becomes:

|-x|=12\\x=12

which is our second possible answer.

Then the set of solutions is: {-12, 12}
