Determine whether the values in the table represent a direct variation. If yes, write an equation to represent the relationship.

Answers

Answer:

No

Step-by-step explanation: No unit rate

Answer:

no

Step-by-step explanation:

there is no direct variation the changes in both x and y are not constant. In y, it is first 62 then it becomes 140. The change here is 78. However, for the next two numbers ( 140 and 256), the change should also be 78.  That's how you would know that it is constant and represents a direct variation. But in this case it isn't.

Joseph earns $1070 monthly. Of that, $160.50 is withheld for taxes. What percent of Joseph's earnings is withheld?

Answers

Answer:

15%

Step-by-step explanation:

Percentages are just division.

The percentage of Joseph's earnings withheld for taxes = money spent on taxes/money earned

Percentage = 160.50 / 1070

Percentage = 0.15 = 15%

0.15 = 15% because to get percentages from decimals, you multiply the decimal by 100

Therfore, 15% of Joseph's money is withheld for taxes.

I hope this helps!

The total amount that was withheld from Joes earnings was 1.5%

The volume of a cereal box is 156 in.

What is the volume of the box if it is scaled down by a factor of

1/10 (one over ten)

Answers

Answer:

15.6 in.

Step-by-step explanation:

If the volume of the box is scaled down by a factor of 1/10, that means you just have to move the decimal over to the left by one place value, making the new volume 15.6 in because behind the 156 there's an invisible decimal in case you need it.

15.6 as it’s 156 divided by 10 (the scale factor).

Answers

Answer:I would presume 15

Step-by-step explanation:

I haven’t done any math yet but they should each have 1 head

5 parrots and 10 puppies

Each parrot has 2 feet so 5*2 = 10. Each puppy has 4 feet so 4*10= 40. So 40+10= 50 feet and 10+5= 15 heads

Isaac is making sandwiches for a group of friends. He needs 3 ounces of meat for each sandwich.

Part A: Isaac is not sure how many sandwiches he will be able to make. Write an expression with a variable that represents the amount of meat Isaac needs for his sandwiches. Identify what the variable represents.

Part B: If Isaac has 18 ounces of meat, how many sandwiches can he make? Create an equation and show all work to solve it.

Answers

Part A:

y=3x
In which:
Y=ounces of meat
X=number of sandwiches

Part B:

18=3x

X=6, therefore he can make 6 sandwiches.
Part A: The expression is 3x. X represents the amount of sandwiches.

Part B: Isaac will be able to make 6 sandwiches with 18 ounces of meat. The equation is 3x=18
First get the variable on its own by dividing 3 from 3 and 18. Making it x=6 meaning the answer is 6 because x represents the amount of sandwiches.
