Drew has two cats. One cat weighs 17 pounds, and the other one weighs 1212 pounds. Audrey’s dog weighs 33 pounds.
What is the difference in ounces between Audrey’s dog and the combined weights of Drew’s cats?
Enter your answer in the box.
Answer:
48 ounces.
Step-by-step explanation:
Steps:
Combine the weight of the cats.
12 (assuming it is a typo, 1212 pounds is a pretty big cat!) + 17 = 30 pounds
Convert to ounces.
33 pounds = 528 ounces
30 pounds = 480 ounces
Subtract the two/find the difference.
528 - 480 = 48.
The difference in ounces between Audrey's dog and the combined weights of Drew's cats is 48 ounces.

2. The ratio of 7th graders to 8th graders in student council is 2:3.
If there are 51 8th grade students in student council, what is the
total number of students in student council?
Help me please thank you kindly
Answer:
85 students
Step-by-step explanation:
Given
[tex]7th : 8th =2 : 3[/tex]
[tex]8th = 51[/tex]
Required
Find the total number of students
We have:
[tex]7th : 8th =2 : 3[/tex]
Substitute: [tex]8th = 51[/tex]
[tex]7th: 51 = 2 : 3[/tex]
Express as fraction
[tex]\frac{7th}{51} = \frac{2 }{ 3}[/tex]
Multiply both sides by 51
[tex]51 * \frac{7th}{51} = \frac{2 }{ 3} * 51[/tex]
[tex]7th= \frac{2 }{ 3} * 51[/tex]
[tex]7th= 2 *17[/tex]
[tex]7th= 34[/tex]
So, the total is:
[tex]Total = 7th + 8th[/tex]
[tex]Total = 34 + 51[/tex]
[tex]Total = 85[/tex]
If the surface area of the box of cereal is 272 inches squared, find the length of the box.
Answer:
x= 8 inches
Step-by-step explanation:
you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-
dimensions of the box:
12 in x 2 in x ?
=272 square inches
and we know that there are 6 faces
area= 2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)
area = 272 sq. in. = 48 + 4x + 24x
272 = 48 + 28x
272 - 48 = 28x
224 = 28x
x = 8 inches
good luck :)

Given the graph of f(x), fund the value of f(4).
Options: -1, 1, 2, 4
Answer:
2
Step-by-step explanation:
the y-value of an x-value of 4, according to the graph, is 2
Answer:
2
Step-by-step explanation:
This question is asking you to find the value of f(x) which is really just the y-coordinate. You need to find the y-coordinate for f(4), which means when x=4. So, go to the line on the graph where x=4 and find the point that lies there. In this case, when x=4 the y-coordinate is 2. The coordinates for this point are (4,2) and can be seen on the far right side of the graph.
24 swimmers are swimming in the pool. 9 of them are female. What fraction of swimmers are male?
Answer:
15/24 or 5/8
Step-by-step explanation:
Well 9 are female
The rest of the 24 has to be male so
24-9=15
15/24 or 5/8
The fraction of male swimmers is 5/8.
Given,
24 swimmers are swimming in the pool.
9 of them are female.
We need to find what fraction of male swimmers.
How do we find fraction of items from the total items?We write in two parts numerator and denominator.
= Numerator / Denominator
= Number of required items / Total number of items
Find the total number of swimmers.
= 24
Find the number of male swimmers.
= Total swimmers - Female swimmers
= 24 - 9
= 15
Find the fraction of male swimmers.
= Number of male swimmers / Total number of swimmers
= 15 / 24
Taking out the common factor
= 3 x 5 / 3 x 8
= 5/8
Thus the fraction of male swimmers is 5/8.

Cam borrows $1,00 from her bank. She will pay back the loan at a simple annual interest rate of 4% over 4 years. How much will she pay back altogether?
15 people working 5 hours per day can make 30 units of a product in 10 days. Assuming all other factors remaining
constant and people of same efficiency are used to make the same products, in how many days can 10 people
make 10 units of the product if each of them works 10 hours per day?
SELECT ONLY ONE
2.5 days
7.5 days
12 days
26 days
The required number of days is 2.5 days
First, we need to calculate the amount of units generated per day.
If 15 people working 5 hours per day can make 30 units of a product in 10 days, then the amount of units per day is calculated as:
Units per day = (15*5*10)/30
Units per day = 750/30
Units per day = 25 units/day
If people of the same efficiency are used to make the same products, the number of days needed by 10 people to make 10 units of the product if each of them works 10 hours per day will be;
Number of days = (25*10)/10*10
Number of days = 250/100
Number of days = 2.5 days
Hence the required number of days is 2.5 days
