What percent of 60 is 15

Answers

25%.

15 = 25%
30 = 50%
45 = 75%
60 = 100%

15/60 = 1/4 or 25 %

or
n% x 60 = 15 (the statement you wrote above changed into math)

.60n = 15 What allows me to move the decimal back two places? Normally you can change a percent to a decimal by moving it back two places. But if you don't know what the % is, you can move the number you are multiplying by back two places instead.
For example: 37 x .45 = .37 x 45 both = 16.65 - this shows that it doesn't matter which number is moved back two places - the answer will be the same. You can't move n% back two places (because you can't move a number you don't know back two places) so just move the number you are multiplying by, namely 60, back two place - that is how I got .60

.60n=15
.60 .60 divide both sides by .60

n= 25%

The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?

Answers

Answer:

y = 12 + 0.75 x

Step-by-step explanation:

Here, x represents the number of batteries used for a toy and y represents total estimated total cost,

Since, the cost of a toy = $ 12,

And, the cost of one battery = $ 0.75,

⇒ The cost of x batteries = 0.75 x dollars,

Since, total cost = the cost of the toy + the cost of x batteries

⇒ y = 12 + 0.75 x

Which is the required equation that represents the given situation.

The answer is:
y=0.75x+12

phaedra would like to buy a blouse costing $27, which is $3 more than 4 times the amount of money she has saved so far. how much more does she need to buy the blouse

Answers

The answer is 3 because 4x6=24 and add 3 is 27 so she will need 3 dollars.

it cost 27$

since its 3 more dollars then 4 times the amount of money she saved then

27-3=24

since its 4 times the amount of money you do 24/4 divide it by 4=6

then try it forwards do 6 x 4+3=27

then you do 27-6 cause she has 6 dollars

27-6=21

so she needs 21 more dollars to buy the blouse

Which strategy best explains how to solve this problem? Colin is preparing for a marathon by running in his neighborhood. The first week, he runs one block. The next week, he runs twice as many blocks as the first week (2 blocks). Each week, he plans to run twice as many blocks as he ran the week before. How many blocks will Colin run by the end of the sixth week? A. Use objects to model the problem. Put out 1 chip to represent the blocks run in week one. Put out twice that amount for week two. Put out twice that amount (from week two) for week three. Do this 3 more times, putting out twice the amount from the previous week each time. B. Make a table. In the first row, write first week - 2 blocks. In the next row, write second week - 4 blocks. In the third row, write third week -6 blocks. Continue this pattern for three more rows. C. Write a number sentence. (1 + 2) × 6 = x Add the number of blocks run in the first and 2nd week. Then multiply the sum by the number of weeks (6).
