Answer:

A. (z+9) (z+8)

Step-by-step explanation:

Answer:

(z+8)(z+9)

Step-by-step explanation:

The first step is to look at the signs. All the signs are positive so we know that the signs in our factored equation will be positive as well. This tells us that we just need to find what factors of 72 can add up to 17. So, we can get 72 with 36 times 2, 24 times 3, 18 times 4, 12 times 6, and 8 times 9.  36 + 2 does not equal 17, 24 + 3 does not equal 17, 18 + 4 does not, 12 + 6 does not, and 8 + 9 does! So since 8+9=17, we can plug those in. So we take our normal factor form (a variable + or - a number)(a variable + or - a number). Our variable is z, and our signs are positive, and our numbers are 8 and 9. To check use FOIL (multiply the First, Outer, Inner, then Last terms and combine like terms to see if you get your original problem.

Answer:

254.34 m^2

Step-by-step explanation:

To know the amount of land that needs to be cleared, we must calculate the area that this land would occupy.

We know that the area would be determined by:

A = pi * r ^ 2

the radius is half the diameter:

r = d / 2 = 18/2

r = 9

the radius equals 9 feet, replacing:

A = 3.14 * 9 ^ 2

A = 254.34

Therefore, an equivalent amount of land 254.34 square meters would have to be cleared so that it can be built

Answer: I believe it would be -1.5

Step-by-step explanation: You would divide both sides of the equation by -4 which would give you x = -1.5

Answer:

67,500 men

Step-by-step explanation:

Percent of children = 20% (.2)

30,000 x 5 = 150,000 (Total pop.)

150,000-30,000 = 120,000 (Pop. minus children)

.35 (Percent of women) x 150,000 =52,500

120,000-52,500 = 67,500

Answer:

67,500

Step-by-step explanation:

20 percent of the population is children. 45 percent is men. If children population is 30000, you multiply by 2 to get 40 percent. That means that if men were 40 percent, men population would be 60000. When you add another 5 percent to get 45 percent, it makes 67500 men.

Answer:

x = 2

y = 6 1/3

Step-by-step explanation:

5x - 6y = -32

3x + 6y = 48

-----------------

8x = 16

x = 2

5(2) - 6y = 48

10 - 6y = 48

-6y = 48 - 10

-6y = 38

y = 6 1/3

Answer:

46

Step-by-step explanation:

turn the percentage into a fraction

so 20% is equal to 2/10.

230 is the whole number so multiply is by the numerator which is 2

230 x 2=460

and divide it by the denominator which is 10

460/10=46

Answer:

Carter's coins could be;

3 of 5¢, 2 of 10¢, 1 of 25¢, and 1 of 50¢

Step-by-step explanation:

The available coin denominations are;

1¢ = 1 penny, 5¢, 10¢, 25¢, 50¢, and $1.00

Since the coins are more than $0.95, we can have;

5¢ × 3

10¢× 2  

25¢× 1

50¢

Total = $1.00

That is his coins could have been 3 × 5¢, 2 × 10¢, 1 × 25¢, and 1 × 50¢, to make a total of 7 coins with an amount value of $1.00.

Answer:

4/3 ft

Corrected question;

Francine has a piece of wood that is five 5/12 feet long she uses three 1/4 feet of the wood from a science project how much for just Francine have left.

Step-by-step explanation:

Given;

Francine has a piece of wood that is five 5/12 feet long.

Total amount of wood T = 5 × 5/12 ft = 25/12 ft

she uses three 1/4 feet of the wood from a science project.

Amount of wood Used U = 3 × 1/4 = 3/4 ft

The amount of wood left equals the total amount of wood minus the amount of wood used;

The amount of wood left L = T - U = 25/12 - 3/4

L = 25/12 - 9/12

L = 16/12

L = 4/3 ft

Answer:

n = -5

Explanation:

6n + 12 − 8n = 22

[ Simplify both sides of the equation ]

6n + 12 − 8n  =22

6n + 12 + −8n = 22

(6n + −8n) + (12) = 22 [Combine Like Terms]

−2n + 12 = 22

−2n + 12  =22

[ Subtract 12 from both sides ]

−2n + 12 − 12 = 22 − 12

−2n = 10

[ Divide both sides by -2 ]

-2n / -2 = 10 / -2

n = -5

Answer:

n = -5

Step-by-step explanation:

6n + 12 - 8n = 22

Combine like terms

-2n +12 = 22

Subtract 12 from each side

-2n +12-12 = 22-12

-2n =10

Divide each side by -2

-2n/-2 = 10/-2

n = -5

Answer:

7n + 14 and 7(n + 2)

Step-by-step explanation:

We know that since our triangle is isosceles, then two of the sides are the same. Given in the problem, we know that these two congruent sides are both 2n + 7. We also know the third side is 3n.

Perimeter is essentially just the sum of the side lengths of the figure. We simply need to add 2n + 7, 2n + 7, and 3n together:

P = 2n + 7 + 2n + 7 + 3n

Combine like terms:

2n + 2n + 3n + 7 + 7

7n + 14

That's one way we can write it. Another way is to factor out the 7:

7n + 14 = 7(7n/7 + 14/7) = 7(n + 2)

Thus, our two expressions are: 7n + 14 and 7(n + 2).

look, area = length x width

so that means that the area of this rectangle is

= 11 1/2 * 8

= 23/2 * 8

= 23 * 4 (simplified)

= 92 in^2

Answer:

[tex]92in.^{2}[/tex]

Step-by-step explanation:

Area of a rectangle= L×W

If length= 11[tex]\frac{1}{2}[/tex]in. and width= 8in.,

∴ Area = 11[tex]\frac{1}{2}[/tex]in. × 8in.

           = [tex]\frac{23}{2}[/tex] × [tex]\frac{8}{1}[/tex] [tex]in.^{2}[/tex]

Answer:

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

The median is the middle number in a set of numbers.

First what we need to do is put the numbers from least to greatest (ascending order).

1, 2, 10,6, 4, 4, 6, 3, 1, 4

1, 1, 2, 3, 4, 4, 4, 6, 6, 10

Now that we have ordered them, which one(s) is/are in the middle?

We have two numbers that share the middle. They are 4 and 4.

In cases where two numbers share the middle, we average them out. We do this by adding our two numbers together and then dividing by 2.

4 + 4 = 8

8 ÷ 2 = 4

Therefore our median is 4!

Answer:

Step-by-step explanation:

Both pools were filled 6 inches from the top.

12 inches = 1 feet

6 inches = 6/12 = 0.5 foot

Considering Theresa's pool, it is rectangular. The formula for determining the volume if the rectangular pool is

Volume = length × width × height

Height filled is 4 - 0.5 = 3.5 feet

Volume = 30 × 15 × 3.5 = 1575 ft³

Recall, 1 cubic feet = 7.48 Us gallons

Therefore,

1800 cubic feet = 1575 × 7.48 = 11781 gallons of water

Theresa fills her pool using city water at a rate of $3.95 per 100 gallons of water. It means that the amount she paid to fill her pool is

3.95 × 11781/100 = $465.35

Considering Nancy's pool, it is cylindrical. The formula for determining the volume if the cylindrical pool is

Volume = πr²h

Diameter = 24

Radius = diameter/2 = 24/2 = 12 ft

Volume = 3.14 × 12² × 3.5 = 1582.56 ft³. Converting to gallons, it becomes

1582.56 × 7.48 = 11837.55 gallons of water.

Nancy fills her pool with a water delivery service at a rate of $200 per 6000 gallons.

It means that the amount she paid to fill her pool is

200 × 11837.55/6000 = $394.59

Therefore, Theresa paid more to fill her pool.
