A square mirror has an area of 25 square feet. How long is each edge of the mirror?

Answer:

the answere is 100

Step-by-step explanation:

Answer:

B. 17.899, 18.1, 18.31, 18.879

Answer:

D

Step-by-step explanation:

Since this is right triangle, we can use the Pythagorean Theorem.

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse.

14 and 16 are the legs, because they form the right angle. x is the hypotenuse, because it is opposite the right angle.

14^2+16^2=x^2

Evaluate the exponents

196+256=x^2

Add

452=x^2

To get this is simplest radical form, find the greatest square root that divides evenly into 452

4 is the greatest square root. 4 times 113 equal 452

So, we have

[tex]\sqrt{4}\sqrt{113}[/tex]

Take the square root of 4

2[tex]\sqrt{113}[/tex]

So, choice D is correct.

Answer:

a = 3

Step-by-step explanation:

6(a+3)=2a+30

Distribute

6a + 18 = 2a+30

Subtract 2a from each side

6a + 18 -2a= 2a+30-2a

4a  +18 =30

Subtract 18 from each side

4a+18-18 = 30-18

4a = 12

Divide each side by 4

4a/4 = 12/4

a = 3

Answer:

a). The volume of the pyramid on the left is greater by 2 inches cubed.

Step-by-step explanation:

The volume of a rectangular based pyramid is

V = [tex]\frac{1}{3}[/tex] w b h

Where w, and b are the lengths of the base of the pyramid, and h is the height of the pyramid

Substitute the values given for both pyramids into the equation, and solve for V

Left Pyramid:

V = [tex]\frac{1}{3}[/tex] w b h

V = [tex]\frac{1}{3}[/tex] * 7 * 6 * 3

Volume of Left Pyramid = 42 [tex]inches^{3}[/tex]

Right Pyramid:

V = [tex]\frac{1}{3}[/tex] w b h

V = [tex]\frac{1}{3}[/tex] * 4 * 3 * 10

Volume of Right Pyramid = 40 [tex]inches^{3}[/tex]

Subtract the two volumes to find the difference in volume

42 - 40 = 2 [tex]inches^{3}[/tex]

Answer:

The volume of the pyramid on the left is greater by 2 inches cubed.

Step-by-step explanation:

Answer:

Today we have technology that allows us to capture the sun's free and unlimited energy. The United States should focus its research & development efforts to make solar energy our country's main energy source by the year 2050. Solar energy is a renewable source because of the sun, and it does not produce any waste products. We are able to use solar panels & other devices to create renewable electricity for just about anywhere. It is safer and cleaner than other resources. We should seek to do this throughout the whole country so it can help our environmental status and solve the problem of running out of limited resources.

Step-by-step explanation \

Vm = Volume of the men's basketball

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

Vm = (4/3)*pi*(5)^3 ... diameter = 10 --> radius = 10/2 = 5

Vm = 523.598775598299 cubic inches

Vw = Volume of the women's basketball

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

Vw = (4/3)*pi*(4.5)^3 ... diameter = 9 --> radius = 9/2 = 4.5

Vw = 381.70350741116 cubic inches

Difference in volume = Vm - Vw

Difference in volume = 523.598775598299 - 381.70350741116

Difference in volume = 141.89526818714 cubic inches

This result is approximate

(x+6)( x^2 -2)

Step-by-step explanation:

x^3 +6x^2 -2x-12

We can factor by grouping

x^3 +6x^2      -2x-12

Factor x^2 out of the first group      and -2 out of the the second group

x^2 (x+6)  -2 (x+6)

Now factor out (x+6)

(x+6)( x^2 -2)

Answer:

21.429 grams per day

Step-by-step explanation:

15g times 10 =150g

150g/7 =21.429g per day

Final answer:

A bird that eats 10 times its weight in food per week, with a weight of 15 g, consumes approximately 21.43 g of food per day.

Explanation:

If a bird weighing 15 g eats 10 times its weight in food in a week, we first calculate the total amount of food the bird eats in a week and then divide that by 7 to find the daily intake.

First, we calculate the weekly food consumption:

The bird's weight = 15 g

Total weekly food intake = 15 g × 10 = 150 g

Daily food intake = Total weekly intake ÷ 7

Daily food intake = 150 g ÷ 7 ≈ 21.43 g

Therefore, the bird eats approximately 21.43 grams of food per day.

Answer:

5 runners

Step-by-step explanation:

By looking at the graph, the number of runners in the 5-6 mile category is 5.

Answer:5

Step-by-step explanation:

Using the original scale of 2 inches = 5 feet, the living room is 20 feet wide. With the new scale of 1 inch = 44 feet, the width of the living room on the new blueprint would be 2.2 inches.

To solve this problem, one must first determine the actual width of the living room using the original scale. According to the original scale, 2 inches represent 5 feet. This would mean that the actual width of 8 inches would represent (8 / 2) * 5 = 20 feet. Now, set up a proportion with the new scale, which is 1 inch = 44 feet. If x is the width on the new blueprint, we would have x / 44 = 1 / 20, solving for x gives us x = 44 / 20 = 2.2 inches. Therefore, the width of the living room on the new blueprint would be 2.2 inches.
