What are the 2 numbers when 30 is the product and -11 is the sum
MArishka [77]

the answer would be -5 and -6.

-5 + -6 = -11 and -5 * -6 = 30 because when multiplying, you cancel out the negative sign when you've got an even amount of negatives.

A sphere has volume 463.01 cm^3. What is the radius of the sphere? A second sphere has a radius half as long as this radius. Wha
Mumz [18]

Answer:

1: r = 2.4 cm

2: V = 57.8765 cm^3

Step-by-step explanation:

1:

The volume of a sphere is given by V = (4/3) * pi * (r^3), being 'r' its radius.

So if the volume is 463.01 cm^3, we have that:

463.01 = (4/3) * pi * (r^3)

463.01 * 3 = 4 * 3.14 * r^3

r^3 = 463.01 * 3 / (4 * 3.14) = 110.59156

r = 4.8 cm

2:

The radius of the second sphere is 4.8/2 = 2.4 cm, so its volume is:

V = (4/3) * 3.14 * (2.4^3) = 57.8765 cm^3

A rectangle and a square have the same perimeter. the rectangle is of length 6cm and has an area of 48cm², find the length of th
EleoNora [17]

<em>The length of the square​ that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>

<h2>Explanation:</h2>

Let's call:

A_{s}:Area \ of \ square \\ \\ A_{r}:Area \ of \ rectangle \\ \\ P_{s}:Perimeter \ of \ square \\ \\ P_{r}:Perimeter \ of \ rectangle

From the question, we know that:

  • <em>A rectangle and a square have the same perimeter.</em>

So:

P_{s}=P_{r}

Moreover:

  • <em>The rectangle is of length 6cm and has an area of 48cm²</em>

Accordingly:

For \ Rectangle: \\ \\ L:Length \\ W:Width \\ \\ A_{r}=L\times W \\ \\ 48=6W \\ \\ W=8

Also:

A_{s}=s^2 \\ \\ S:Side \ of \ square

From the statement of perimeters:

P_{s}=P_{r} \\ \\ \\ But: \\ \\ P_{s}=4s \\ \\ P_{r}=2W+2L \\ \\ \\ Then: \\ \\ 4s=2W+2L \\ \\ \\ But: \ W=8 \ and \ L=6 \\ \\ 4s=2(8)+2(6) \\ \\ 4s=16+12 \\ \\ 4s=28 \\ \\ \boxed{s=7cm}

Finally, <em>the length of the square​ that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>
