Diego made 6 boxes of spaghetti to feed the 20 people who attended his dinner party.

Next time, 50 people are coming! How many boxes of spaghetti should Diego buy to feed all those people?


Diego needs to buy ? boxes of spaghetti.

Answers

Answer:

15 boxes!

Step-by-step explanation:

Hope this helps!

The number of boxes of spaghetti required to feed 50 people will be equal to 15 boxes.

What is the ratio?

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is.

A ratio divides two quantities to compare them.

As per the given information in the question,

Total number of people who attended the party first time = 20

Number of spaghetti boxes required to feed 20 people = 6

Let the number of boxes required to feed 50 people be x.

So, the ratio will be,

6 boxes = 20 people

x boxes = 50 people

Perform cross-multiplication,

20x = 50 × 6

x = (50 × 6)/20

x = 5 × 3

x = 15 boxes.

Your parents take your family out to dinner on a Wednesday night when they have a 15% off coupon. Your parents wanted to give the waiter a 18% tip for doing a great job. If the total amount of the dinner was $42.00, how much tip money should the waiter get? What is the new total? **Tip is given before the discount**

Answers

Answer:

a. Tip is before the discount so the waiter will get;

= 42 * 18%

= $7.56

b. New total;

Coupon of 15% off applies;

= 42 * (1 - 15%)

= $35.70

Add the tip;

= 35.70 + 7.56

= $43.26

Two large and 1 small pump can fill a swimming pool in 4 hours. One large and 3 small pumps can also fill the same swimming pool in 4 hours. How many hours will it take 4 large and 4 small pumps to fill the swimming pool? Please help me answer I'm in 5th grade and this is so hard.

Answers

Answer:

Let's define.

L = rate at which the large pump fills the pool.

S = rate at which the small pump can fill the pool.

We have two relations:

"Two large and 1 small pump can fill a swimming pool in 4 hours."

(2*L + S)*4h = 1

"One large and 3 small pumps can also fill the same swimming pool in 4 hours."

(L + 3*S)4h = 1

Then we have the system of equations:

(2*L + S)*4h = 1

(L + 3*S)4h = 1

To solve this system, we need to isolate one of the variables in one of the equations, i will isolate S in the first equation:

S = 1/4h - 2*L

Now we can replace that in the second equation:

(L + 3*(1/4h - 2*L))4h = 1

L + (3/4h) - 6*L = 1/4h

-5*L = 1/4h - 3/4h = -2/4h

L = (2/4h)*(1/5) = (2/20h) = 1/10h

This means that one large pump needs 10 hours to fill one pool.

With this, we can find the value of S:

S = 1/4h - 2*L = 1/4h - 2/10h = 5/20h - 4/20h = 1/20h

This means that a small pump needs 20 hours to fill a pool.

Now we can answer:

How many hours will it take 4 large and 4 small pumps to fill the swimming pool?

We need to solve the equation:

(4*(1/10h) + 4*(1/20h))*T = 1

We need to find the value of T.

T = 1/((4*(1/10h) + 4*(1/20h)) = 1.67 hours.

This means that 4 large and 4 small pumps need 1.67 hours to fill a pool.
