Question

1. 72% of the students in Math 6 at AZVA are currently passing mastering their lessons. If 324 students are currently mastering their math lessons, how many students are in Math 6?
a) Use a percent equation OR set up a proportion that you will use to solve the problem.
Percent equation





a) Solve the problem. Show your work. 0.72x = 324 x = 324 / 0.72 x = 450 students


2. 2. A bag of dog food weighs 20 lb. 15% of the weight is oats.

a) Set up an equation OR proportion to find the weight of the oats in the dog food.





b) What is the weight of the oats in the dog food? Show your work.


3. Some students were asked what kinds of animals they have at home. The results are below:

(a) List the animals in order of popularity from most popular to least popular.


(b) I estimated that 250 students were interviewed. Based on my estimate, how many students have an “other” pet? Show your work.




(c) If 75 students have cats, was my estimate of 250 students correct? If not, what is the actual number of students interviewed? Explain.



THE CHART IS FOR NUMBER THREE RIGHT AFTER IT SAYS BELOW. IF YOU PUT ANY COMMENT THAT DOESN'T ANSWER MY QUESTION I WILL DELETE THE ANSWER AND TAKE AWAY THE POINTS I GAVE YOU . IF YOU ANSWER RIGHT I WILL GIVE YOU 109 POINTS I WILL ALSO MARK BRAINIEST AND PUT THANKS OVER UR NAME

Answer 1

Answer:

1. a. 72/100 = 324/x

72x = 32,400

b. 450 students are in Math 6

2. a. o = 3b

b. o = 3 pounds

3. a. Most popular animals:

A. Dogs - 67%

B. Cats - 20%

C. Other - 8%

D. None - 4%

E. Horses - 1%

b.  20 students

c. If 75 students have cats, the estimate of 250 students isn't correct.

The actual number of students interviewed is 375.

Step-by-step explanation:

1. a. Let's use the following equation to solve the question:

x = Students that are in Math 6

72/100 = 324/x

72 * x = 324 * 100

72x = 32,400

b. Let's solve the equation, as follows:

x = 32,400/72

x = 450

450 students are in Math 6

2. a. The equation is:

o = 0.15 *20b

o = 3b

where, o = weight of oats in pounds and b = number of dog food bags

b. Let's find out the weight of the oats in one dog food bag, using our equation:

o = 0.15 *20b

o = 0.15 *20 * 1

o = 3 pounds

3. a. Most popular animals:

A. Dogs - 67%

B. Cats - 20%

C. Other - 8%

D. None - 4%

E. Horses - 1%

b. If 250 students were interviewed, the 8% who answered "other" are:

8% of 250 = 0.08 * 250 = 20 students

c. If 75 students have cats, the estimate of 250 students isn't correct.

The 20% of 250 is 50, not 75.

0.2 * 250 = 50

The actual number of students interviewed is:

x = Actual number of students interviewed

75/x = 20/100

20x = 7,500

x = 7,500/20

x = 375

The actual number of students interviewed is 375.
