Suppose Monica Walks 1 kilometer every 15 minutes. How many meters further can she walk in 1 hour at this new rate? EXPLAIN how you found your answer

Answers

Well every 15 minutes he walks 1 step. So divide an hour which is 60minutes by 15 minutes. Then the answer to that you multiply by 1. So the equation would be (60/15)x1= and you will find the answer.

A restaurant claims to have served 352,000,000 hamburgers. What is this number in scientific notation?​

Answers

Answer:

3.52 × 10⁸

Step-by-step explanation:

Scientific notation is written in: Number that is in the ones place × 10^power.

Here, the number is 3.52, since 3 has the largest placement.

The power on the 10 should be the number of 0's on 352,000,000/3.52. That is 100,000,000. That number has 8 0's, so the power is to the 8th.

Putting that together, this number in scientific notation in 3.52 × 10⁸.

A gym charges a $59 fee plus $7.70 per week that person attends. The total cost y for any number of weeks x can be given using the equation y=7.7x+59xa)state the slope and y intercept
b)describe what the slope and y intercept represent.

Answers

Firstly the equation would be y=7.7x+59
(A)The slope is 7.7 (B) and shows that there is a 7.7 charge per week the person attends.
(A)The y intercept is 59 (B) and is the initial fee that the gym charges.
