A store makes a profit of $8 on a sweater after a markup of 40%. What is the selling price of the sweater?

Answers

Answer 1
Answer: Use ratios: (40)/(100)(8)/(7)

Since 40/8=5, then you do the same on the bottom. 100/5=20, so the sweater was originally $20.

Answers

i think its 16 if it's not then a least i helped

Final answer:

1/10 the value of 237 is achieved by dividing 237 by 10, resulting in 23.7. This concept is connected to the exponential method where the decimal is shifted as per the power of 10.

Explanation:

To find 1/10 the value of a number, you simply divide that number by 10. In this case, to find 1/10 the value of 237, you divide 237 by 10.

Step 1: Setup the division problem, 237 ÷ 10.

Step 2: Perform the division, which gives us 23.7.

So, "1/10 the value of 237 is 23.7". This concept is related to the exponential method where the power (exponent) of 10 is equal to the number of places the decimal is shifted.

Alex swum a total of 11.5 hours during the work week and then swam a total of 2.6 hours on the weekends. He swam the same number of hours each week for 7 weeks. What was the total number of hours Alex swam after 7 weeks?

Answers

Alex swam at least 98.7 hours.

You can do 90 sit-ups in 2 minutes. Your friend can do 135 sit-ups in 3 minutes. Do these rates form a proportion? Explain.

Answers

My situps in 1 minute = 90/2 = 45

Friend sit-ups in 1 minute = 135/3 = 45

So, proportion would be 45/45 = 1.

As it is forming directly one, so we can say these rates did not form a proportion.

PLEASE ANSWER! VERY IMPORTANT LAST IMPORTANT QUESTION! MUST BE CORRECT! POINTS GIVEN! Emma said that when you multiply three negative decimals the answer will be positive. Use these numbers to answer the questions: –2.5, –3.8, –2.7, –4.5, 1.4

Emma changed her statement to say that when you multiply two negative decimals and a positive decimal the answer will be positive. Is Emma’s new statement always true, sometimes true, or always false? Write two equations to support your answer.

Answers

Emma is always. When solving, you use the PEMDAS method going from left to right.

Your equation would be something like  " -2 * -2 * 4"
Because you would start with (-2 * -2) = 4 and then move to 4 * 4 = 16

If your equation were something like " -2 * 3 * -2"
You would do -2 * 3 = -6 and then move to -6 * -2 = 12

Remember "Two negatives = a positive"
