A cyclist accelerates from rest at a rate of 7.0 m/s2. How long will it take the cyclist to reach a speed of 18 m/s?
(Its really a subject for science, but I didn't want to put the wrong thing)

Answers

Answer 1

9514 1404 393

Answer:

  2 4/7 seconds

Step-by-step explanation:

Velocity and (constant) acceleration are related by ...

  v = at

Filling in the numbers, we can solve for t:

  18 m/s = (7 m/s²)·t

  t = (18 m/s)/(7 m/s²) = (18/7) s = 2 4/7 s

It takes the cyclist 2 4/7 seconds (about 2.57 seconds) to reach 18 m/s.

Comment on the subject

Problems involving position and its derivatives can reasonably be posted in the Math section. When energy or mass get involved, the Physics section is a better place. The relevant formulas for those are not always covered in algebra classes.

Answer 2

Mr. Jackson has a total of 12 employees. He wants to buy each employee 3 aprons that will cost $7.79 each, 1 cap that will cost $5.68, and a t-shirt that costs $13.99. How much will Mr. Jackson need to spend to purchase the items for his employees?

Answers

12/3 is 4 so multiply each by 4 so 7.79 x 4 is 31.16 5.68x4 22.72 13.99x4 55.96


31.16 + 22.72+ 55.96

Answer: $109.84

Answer: $516.48

Step-by-step explanation: Multiply 7.79 by 3 because it's 3 for each employee then multiply by 12 for each employee which equals 280.44. then 5.68 x 12 which is 68.16 for the cap. then 13.99 x 12 for the shirt which is 167.88. add 280.44, 68.16, and 167.88 to get 516.48.

Hello again davetriona12! I can help you.

We have 2.99, 3.19, 3.39, and 3.79

In order to solve this, we need to find out how much is being added every time. To do this, we will subtract 2.99 from 3.19 which gives us 0.20

So each time, 0.20 gets added.

Now that we have that information, we are ready to find the blanks.

For the first blank, we will subtract 2.99 - 0.20 which will give you 2.79

For the second blank, we will add 0.20 to 3.39 which will give you 3.59

Hope this helps you!

Mark's bill for lunch at a restaurant is $14.50, and he wants to leave a 18% tip.
How much should he leave for the tip?

A. $2.18

B. $2.61

D. $261.00

Answers

It’s B because you divide 18 percent from 14.50 dollars.
It would be B. Because 14.50 times .18 equals 2.61. Just put a decimal on it and move it to the right twice and multiply that by 14.50. If you need a better explanation you can message me! Hope this helps!:)

Step-by-step explanation:

Answer:


Meaning: Each floor of the buiding has a height of 15 feet.
Step-by-step explanation:
The missing figure is attached.
By definition, the ratios are used to compare two or more things or quantities.
In this case you must write the ratio of height of the building to the number of floors it has.
You can observe in the figure that the building has a height of 135 feet, and, since it has 9 floors, you can write the following ratio:

Therefore, dividing the numerator by the denominator, you get that the unit rate is:

This means that each floor of the buiding has a height of 15 feet
