2) A. 10

3) B. 72

4) B. 42

5) A. 6

6) B. 90

7) C. less than

10) B. The diameter is two times the size of the radius.

Step-by-step explanation:

1) 12 x 3.14 = 36

2) 20/2 = 10

3) 12 x 2 x 3.14 = 72

4) 7 x 2 x 3.14 = 42

5) 36/3.14 = 12/2 = 6

6) 30 x 3.14 - 90

8) 11 x 2  =22

9) 9 x 2 x 3.14 = 54

Answer:

9*√3

Step-by-step explanation:

The exact value of Sin60 = √3/2

Sin(60)  = opposite side/ hypotenuse

hypotenuse = 18

√3/2 = x / hypotenuse

√3 / 2 = x / 18     multiply by 18

18 √3 /2 = x        divide by 2  

9 √3   = x

uMMMMMMMM I don't know

Answer:

$74,664.76

Step-by-step explanation:

We are to determine the future value of  £45 500

The formula for calculating future value:

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

Future value for the first 5 years =  £45 500 x (1 + 0.045)^5 = $56,701.28

Future value for the remaining 8 years = $56,701.28 x ( 1 + 0.035)^8 = $74,664.76

Answer:

Step-by-step explanation:

when  1/2 inch equals 4 feet the room is  2.25 inches, then

2 1/4 = 8/4 + 1/4  = 9/4

9/4 inches is the scale distance of the room

each 1/2 inch is 4 feet so divide  9/4 by 1/2 then multiply that by 4 to find the distance of the room

9/4 ÷ 1/2  = 9/4

9/4 * 2/1 = 18/4

18/4 = 9/2

9/2 * 4 feet = 9/2 * 4/1

9/2 * 4/1 = 36/2

36/2=18

the room is 18 feet across

then if the scale is 2/3 of an inch is  4 feet , then

2/3 * 9/4 = 18/12

18/12 = 3 inches  is the scale size of Quinto's room

5. 1/5*1/2= 1/10

Answer:

8 CUPS

Step-by-step explanation:

We have to convert gallons and quarts to cups and subtract the values

1 gallon = 16 cups

7 gallons = 7 x 16 = 112 cups

1 quart = 4 cups

26 quarts = 26 x 4 = 104 cups

112 - 104 = 8 cups

Answer:

12+16

24+20

36+81

49+84

99+36

= 23.5

Answer: Its just 5

Step-by-step explanation: Its always the first digit of the number.

Answer:

Answer to question 7: -2x+5y+9

Answer to question 8: 2x-6y+1

Answer:

7.) -2x + 5y + 9 ; 8.) 2x - 6y + 1

Step-by-step explanation:

7.)

7 + 2x + 5y - 4x + 2 ⇒ -2x + 5y + 9

2x - 4x ⇒ -2x

5y ⇒ 5y

7 + 2 ⇒ 9

8.)

-4y + 2x - 2y + 1 ⇒ 2x - 6y + 1

2x ⇒ 2x

-4y - 2y ⇒ -6y

1 ⇒ 1

Answer:

The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent).

Answer:

Step-by-step explanation:

Used t find missing side angles when two sides are present. For example, if you have a short leg and a long leg, you can use the Pythagorean Theorem to find the hypotaneus and vse versa, using it to find the short or long leg if the other two are given.

Answer:

5000

Step-by-step explanation:

Ur car loses 2500 dollars in value per year

Volume = (base area x heigh)/3

base area = 160m x 160m

base area = 25600 m²

Volume = (25600 m² x 91 m) / 3

Volume = 776533.333 m³

the volume is 776533.333 m³

Answer:

Step-by-step explanation:

So you are combining the numbers that look alike practically..

They are asking for how many like term, so you would put how many numbers you see that are different.

-12x - 4x - 72 + 10y^3

-16x - 72 + 10y^3

That is as far as you could go.

There are 3 numbers that look different.

When I say this I mean that one number has no variable, one number has a variable, and another number has a variable and it’s cubed.

So that would be 3 like terms.

And for the simplified form, it’s

-16x - 72 + 10y^3

Hope this helps

Given:

The initial value of car = £2,200

Depreciation rate = 0.5%

To find:

The worth of car after 6 years.

Solution:

Exponential decay model:

[tex]y=a(1-r)^t[/tex]

Where, a is the initial value, r is the rate of depreciation and t is number of years.

Putting a=2200, r=0.005 and t=6, we get

[tex]y=2200(1-0.005)^6[/tex]

[tex]y=2200(0.995)^6[/tex]

[tex]y=2200(0.9703725)[/tex]

[tex]y=2134.8195[/tex]

[tex]y\approx 2134.82[/tex]

Therefore, the worth of the car after 6 years is £2134.82.

Answer:

Step-by-step explanation:

A. The Initial value is the starting value of her business which can be considered $350 since that is what she made the first year. The Slope can be calculated by subtracting the end profit from the initial profit and then dividing by the result of subtracting the end year by the initial year like so...

$350 initial value

[tex]\frac{750 - 350}{2014 - 2010} = \frac{400}{4} = \frac{100}{1 year} =[/tex]  $100 a year increase

B. The equation for this scenario would be  y = 100x + 350

Answer:

100 each year and y=100x+350

Answer:

The DJ can play at the dance for 6 Hours

Step-by-step explanation:

1. Add the decorations and food plus the additional fee of $12

 $175+ $125= $300

2. Subtract the budget and the total so far

 750-300= 450

3. Get the amount owed per hour to DJ and divide by the new budget

  450/75= 6

The DJ can play at the dance for 6 hours

Have a good day!

Answer:

175+125-750/75.
