Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Answer:

14)$9,320.00. 15)Chen has 8 nickels, 2 dimes, and 6 quarters.     16)10%

Step-by-step explanation:

14)A = $9,320.00

I = A - P = $1,320.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

Solving our equation:

A = 8000(1 + (0.055 × 3)) = 9320

A = $9,320.00

The total amount accrued, principal plus interest, from simple interest on a principal of $8,000.00 at a rate of 5.5% per year for 3 years is $9,320.00.

16)R = 1011.1111%/year

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving our equation:

r = (1/1)((1250/112.5) - 1) = 10.11111111

r = 10.11111111

Converting r decimal to R a percentage

R = 10.11111111 * 100 = 1011.1111%/year

The interest rate required to get a total amount, principal plus interest, of $1,250.00 from simple interest on a principal of $112.50 over 1 years is 1011.1111% per year.

The cost that will maximize the demand, considering the quadratic function, is given as follows:

$3.

How to maximize the demand?

The quadratic function representing the demand is given as follows:

y = -10x² + 60x + 180.

The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:

x = -b / (2a)

The coefficients of the quadratic function in this problem are given as follows:

a = -10, b = 60.

The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:

x = -60/(2 x (-20))

x = 3.

Evaluate 5 + 1.3 • 8.7

Answers

Step-by-step explanation:

16.31

.......................

Answer:

16.31

Step-by-step explanation:

You want to start with multiplying because of PEMDAS, so

1.3 x 8.7

so 7 x 3 = 21, and carry the two, then 7 x 1 = 7 + 2 = 9.

at the bottom you now have that it equals 9.1

so, now you start your next line and put a 0.

then, 8 x 3 = 24, of course carry the 2, and 8 x 1 = 8 + 2 = 10.

you will now have 10.40 under that

you then add 9.1 + 10.40 to get your answer of

11.31

lastly, just simply add

11.31 + 5

and you get your final answer of 16.31

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
