How many quarts of pure antifreeze must be added to 3 quarts of a 10% antifreeze solution to obtain a 60% antifreeze solution?
Round to nearest tenth if possible

Answers

Answer 1

Answer:

3.75 quarts, rounded to 3.8 quarts

Step-by-step explanation:

3 quarts of solution is 10% antifreeze, so 0.3 quarts are already antifreeze, and 2.7 quarts are not.

a(the antifreeze we already have)+x(what we're going to add)= 1.5*2.7

Let me explain. If we have 60% antifreeze, 40% is not. 60/40=1.5

Substitute a for 0.3

0.3+x=4.05  Subtract 0.3 from both sides

x=3.75

A lawyer spends $75.00 on 3 staplers and 3 pads of paper. If each stapler costs $21.75, and each pad of paper costs x dollars, which statement is true?

Answers

Each pad of paper cost 3.25. Here is how I found it.

21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25

X = 3.25

Is this what you were looking for?
If staplers cost 21.75 each and there’s 3, you would need to do 21.75x3=65.25
You have 9.75 left for pads of paper and there’s 3 so 9.75/3=3.25

Each pad of paper costs $3.25 or x=3.25

Answers

Answer:

15

Step-by-step explanation:

Hey there!

--------------------------

Answer:

45 cookies in the jar

Step-by-step explanation:

100% - 60% = 40%

Half of the remaining (40%) are oatmeal so half of 40% = 20%.

20% are oatmeal.

100% = 45

The number of customers at Yummy Smoothies during lunch was 3 times more than during breakfast. How many people were at Yummy Smoothies during breakfast? How many people were at Yummy Smoothies during dinner? Let d represent the number of customers at Yummy Smoothies during dinner and b represent the number of customers at Yummy Smoothies during breakfast.

Answers

Answer:

190 people

Step-by-step explanation:

At lunch, there were 120 people.

There were 3 times more people at lunch than breakfast meaning you divide 120 by 3.

120 / 3 = 40

At dinner, there were 10 people less than at breakfast.

40 - 10 = 30

Add up your numbers.

120 + 40 + 30 = 190

B = 40

Answers

Answer:

6

Step-by-step explanation:

First, find the total number for the set of four numbers. To do this, multiply 3.5 and 4. We do this because the mean is division, so we need to get back to the original amount.

3.5 x 4 = 14

Next, we need to find the other total when the mean is 4. There are 5 numbers, which tells us we had to divide the total by 5 to get 4. So, again, we want to multiply the mean, 4, and the 5 to get the total.

5 x 4 = 20

Finally, find the number we added in. To do this, we subtract the two totals.

20 - 14 = 6
