Chris has finished 30% of an art project that has taken him a total of 9 hours so far. If he continues to work at the same rate, how many hours will it take for him to complete the entire project?

Answers

there was already a question like this on here so i’m going off the answer already given: 30 hours, i hope it’s right

If Chris has finished 30% of an art project in 9 hours then he will take 30 hours to complete the whole work if he will work at same rate.

What is rate?

A measure, quantity, or frequency, typically one measured against some other quantity or measure.

How to calculate time?

Let the project contains 100 questions in total.

Chris finished 30% questions so he may finish 30 questions in 9 hours.

So in order to complete the 1 question he took =9/30 hours

In order to complete 100 questions he will take 9/30*100 hours which is equal to 30 hours.

Hence Chris will take 30 hours to complete the project.

Two members of a band want to get word out about their next gig. Jack's plan is that he can pass out 100 fliers a day. Meg has a different strategy. She wants to tell each of her friends about the performance on the first day, and ask each of her 10 friends to each tell a friend on the second day, and then everyone who has heard about the concert would tell a friend on the third day, and so on. Meg's idea can be modeled with the function M(t)=10(2)^2-1, where t is the number of days.

Which plan would work out better in 7 days? What about 5, 8, 9, and 300 days?

Keisha has 45 coins in her piggy bank, consisting of only nickels, dimes and quarters. She has one fewer nickel than she has dimes, and one fewer quarter than three times her number of nickels. How many nickels does she have?

Answers

Answer:

20 nickels, 40 dimes, and 8 quarters

Step-by-step explanation:

This is a system of three equations with three unknowns. Let x = # of nickels, y = # of dimes, and z = # of quarters.

x + y + z = 68 (since there are 68 total coins)

.05x + .10y + .25z = 7

.10x + .05y + .25z = 6 (if the nickels were dimes and the dimes were nickels)

Multiply both sides of the last two equations by 100 to simplify, giving us:

5x + 10y + 25z = 700 or x + 2y + 5z = 140 if you divide both sides by 5.

10x + 5y + 25z = 600 OR 2x + y + 5z = 120 if you divide both sides by 5.

Let's solve the first equation for x. That gives us x = 68 - y - z. We can substitute this result into each of the final two equations to create a system of two equations with two unknowns, which is easier to solve. For the first equation:

(68 - y - z) + 2y + 5z = 140

68 + y + 4z = 140 or y + 4z = 72

For the second equation, we have:

2(68 - y - z) + y + 5z = 120

136 - 2y - 2z + y + 5z = 120

136 - y + 3z = 120

-y + 3z = -16

Now we have our system of two linear equations:

y + 4z = 72

-y + 3z = -16

If we add those two equations together, then we get 7z = 56 or z = 8. If z = 8, we can substitute this into either of the two previous equations. Let's choose the first. This gives us:

y + 4(8) = 72 or y + 32 = 72.

So y = 40. If y = 40 and z = 8, then we know:

x = 68 - y - z = 68 - 40 - 8 = 28 - 8 = 20.

Consequently, there were 20 nickels, 40 dimes, and 8 quarters in the piggy bank.

Joanna is driving 185 miles to visit her family. She drives 68 miles in the morning, stops for lunch, and then drives the rest of the distance. How many miles did she drive after lunch?

Use the variable m to represent the number of miles she drove after lunch.

Which equation represents this situation and its solution?


A. m + 68 = 185; m = 117

B. 185m = 68; m = 17

C. 68m = 185; m = 17

D. m + 185 = 68; m = 117

Answers

Answer:

I believe the answer is A. m + 68 = 185; m = 117
