The senior class is planning an end-of-the-year party to celebrate graduation their total budget for food and drinks is $600 each pair of food cost five dollars and each drink cost one dollar each person at the party gets one player food and wondering with none left over how many people went to the party

Answer:

100 people

Step-by-step explanation:

Since the cost of food = $5

And, the cost of drink = $1.

Thus, the expense of each person = $5 + $1 = $6

And, total budget is: $600

Thus,

⇒

⇒ Number of People = 100

Answer:

100

Step-by-step explanation:

100 people went to people went to the party because if a pair of food costs 5 and each drink is 1 dollar. 5 + 1, the food cost + the drink cost equals 6 and 600, the budget divided by the 6 total cost of the food and drink equals 100. Therefore 100 people attended this party

PLEASE HELP The hose filled the 100-gallon tank in 6 hours. Which shows the flow rate of the hose? a. 0.06 gallons per hour

b. 16.7 gallons per hour

c. 106 gallons per hour

d. 600 gallons per hour

Answer: B. 16.7 gallons per hour

Step-by-step explanation:

The flow Rate of the hose = volume / time.

Volume = 100 gallon.

Time = 6hours.

Flow rate = volume / time

Thus, = 100 (gallons) / 6 (hours)

Flow rate = 16.7 gallons per hour.

b 16.7 gallons per hour

What number is 11 1/3% of 215?

8 + 3/4 - 11 + 1/3 = - 215/12 = - 17 11/12 = - 17.9166666667; Result written as: improper fraction, mixednumber (also called mixed fraction) and decimal number

You can change 215 to 2.15

because 11 1/3% can't change.

So is

2.15x34/3

=43/20x34/2

=731/30

=24 11/30

That's your answer.

because 11 1/3% can't change.

So is

2.15x34/3

=43/20x34/2

=731/30

=24 11/30

That's your answer.

If it takes you 56 seconds to walk from the first (ground) floor of a building to the third floor. How long will it take you to walk from the first floor to the sixth floor (at the same pace, assuming all floors have the same height)?

To cover the first to sixth floors will take 112 seconds or 1 minute 52 seconds.

What are the ratio and proportion?The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

If it takes you 56 seconds to walk from the first (ground) floor of a building to the third floor.

So,

3 floor ⇔ 56 seconds

Divide by 3

1 floor ⇔ 56/3 seconds

Multiply by 6

6 floor ⇔ 56/3 × 6 seconds

6 floor ⇔ 112 seconds

6 floor ⇔ 1 minute 52 seconds.

Hence "To cover the first to sixth floors will take 112 seconds or 1 minute 52 seconds".

Answer:

112 seconds or 1 minute 52 seconds

Step-by-step explanation:

1st floor to the 3rd floor takes 56 seconds

1st floor to the 6th floor is double that so double the time too!

56 x 2 = 112

justine answered 68 questions correctly on an 80 question test. express this amount as a fraction. percent, and decimal.

This is actually a simple division problem. First, let as express this as a fraction. So in order to express it as 68 out of 80, we just have to write the fraction as 68/80. If we would express this in simplest form, then it will 17/20. After that, we will have express it as a decimal. To do this, we just have to divide it in order to get the decimal form. So if we do this, we will get an answer of 0.85. Now in order to turn it into a percentage, we have to multiply it by 100 and you will get 85%

0.85 × 100 = 85%

68 questions answered correctly out of 80 can be expressed as:

a fraction: 17/20

a decimal: 0.85

a percent: 85%

The function A = 15x - x2, where x is the width in yards, gives the area A of a llama pen in square yards. Make a table using 1/2 units from 0 to 10. Graph the function. Use your graph to answer the following question: Which width gives the greatest area?

Which width gives the greatest area?

a.

6 yd

c.

8.5 yd

b.

7.5 yd

d.

10 yd

Answer:

The width which gives the greatest area is 7.5 yd

Step-by-step explanation:

This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen

Arrange the steps in the correct order to perform this subtraction problem. 1.1 × 103 – 4.9 × 102

The answer is, the steps in the correct order to perform this subtraction problem 1.1 × 103 – 4.9 × 102 , is given below.

What is Subtraction?Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here we have,

given that, 1.1 × 103 – 4.9 × 102

the steps are,

- 1=> 1.1 x 10^3 - 4.9 x 10^2

- 2=> 1.1 x 10^3 -10/10 x 4.9 x 10^2

- 3=> 1.1 x 10^3 -0.49 x 10^3

- 4=> (1.1 -0.49) x 10^3

- 5=> 0.61 x 10^3

- 6=> 10/10 x 0.61 x 10^3

- 7=> 6.1 x 10^2
