Answer:

Since the area of the rectangle is 6 square centimeters, you just think of multiples of 6. These multiples will give possible lengths for the rectangle. Possible multiples include: 1&6 2&3 Then you just find the perimeter of the rectangle with your possible side lengths So let's start with: 1&6 So two of the side lengths are 1 And the other two side lengths are 6 So you would just find the sum of the four side lengths to find the perimeter 1 + 1 + 6 + 6 = 14 Now let's try 2&3 Two of the side lengths are 2 The other two side lengths are 3 Now to find the perimeter just add up the four side lengths 2 + 2 + 3 + 3 =10 Now compare the two perimeters Which is bigger? 14? Or 10? Since fourteen is bigger than the greatest possible perimeter for the rectangle is 14cm

In a population of 3 1/4 million people, 2115000 are under the age of 16. Calculate the percentage, to two decimal places, of th

Masteriza [31]

So what we need to do is divide the number of people under 16 by the number of the entire population:

$\frac{2115000}{3250000}$

first, let's get rid of the 0s:

$\frac{2115}{3250}$

now, we can divide:
this is 0.6507....

in order to make this into a percentage, we multiply by 100%:

0.6507*100%=65.07%

the answer is: 65 % (quite a lot!!!)

Answer:

The number is 2. :)

Step-by-step explanation:

4x + 2 = 2x + 6

-2 -2

4x = 2x + 4

-2x -2x

2x = 4

Which expression is equivalent to (3x^4 - 6x^2 + 8x) - (x^4 + 8x^3 - 3x)? <br><br> view image!

AfilCa [17]

Answer:

$2x^{4} -6x^{2} +11x-8x^{3}$

Step-by-step explanation:

1) Remove parentheses.

$3x^{4} -6x^{2} +8x-x^{4} -8x^{3} +3x\\$

2) Collect like terms.

$(3x^{4} -x^{4} )-6x^{2} +(8x+3x)-8x^{3}$

3) Simplify.

$2x^{4} -6x^{2} +11x-8x^{3}$

Ariel has a plastic ice cream cone in her food playset. The ice cream cone is half-sphere sitting on top of a cone. What is the

Svetllana [295]

The approximate volume of the toy ice cream cone is 753.60 cm³

Step-by-step explanation:

The ice cream cone is half-sphere sitting on top of a cone, that means

the radius of the base of the cone is equal to the radius of the

half sphere

To find the volume of the toy ice:

1. Find the volume of the cone

2. Find the volume of half sphere

3. Add the two volumes

∵ The volume of the cone = $\frac{1}{3}$ π r² h, where r is its

radius and h is its height

∵ r = 6 cm , h = 8 cm and π = 3.14

∴ The volume of the cone = $\frac{1}{3}$ (3.14)(6)²(8)

∴ The volume of the cone = 301.44 cm³

∵ The volume of the sphere = $\frac{4}{3}$ π r³, where r is its

radius

∴ The volume of the half sphere = $\frac{1}{2}$ × $\frac{4}{3}$ π r³

∴ The volume of the half sphere = $\frac{2}{3}$ π r³

∵ r = 6 cm and π = 3.14

∴ The volume of the half sphere = $\frac{2}{3}$ (3.14)(6)³

∴ The volume of the half sphere = 452.16 cm³

Add the two volumes to find the volume of the toy ice cream cone

∴ The volume of toy = 301.44 + 452.16

∴ The volume of toy = 753.60 cm³

The approximate volume of the toy ice cream cone is 753.60 cm³
