A 150-pound person uses 5.1 calories per minute when walking at a speed of 4 mph. How long must a person walk at this speed to use at least 230 calories?

45.1 minutes

Step-by-step explanation:

From the question, we are informed that a 150-pound person uses 5.1 calories per minute when walking at a speed of 4 mph. The number of.

minutes that the person must walk at this speed to use at least 230 calories will be:

Let the number of minutes to walk be represented by x

(5.1 × x) = 230

5.1x = 230

x = 230 / 5.1

= 45.1 minutes

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
