The sum of 15 and the product of 5 and v

Answers

v = 3 because if you use the inverse operation of multiplication you do 15/5 which equals 3

15+5v. The sum which is adding and the product which is multiplying. So, 15 plus 5 times "v"!

30 POINTS The graph shows how many inches above the ground, y, the valve on a rotating tire is for a given number of seconds x.

How many degrees is the tire turning every second?

Enter your answer in the box.

Answers

Answer:

180 degrees per second.

Step-by-step explanation:

We have been given a graph that shows the distance covered by a tire or angular velocity of a tire with respect to the number of seconds (x).

Since we know that a tire is a circle and the measure of all the angles of a circle equals to 360 degrees.

We can see from our given graph that the tire completes one rotation in 2 seconds (2.5-0.5), so the distance covered by tire in two seconds will be 360 degrees. This means that the tire turns 360 degrees in each 2 seconds.

$\text{Degrees turned by tire in 2 seconds}=\frac{360^o}{2\text{ seconds}}$

As we are asked to find the degree change by tire per second so we will find the unit rate such that we will have 1 in our denominator. By dividing our numerator and denominator by 2 we will get,

$\text{Degrees turned by tire in every second}=\frac{180^o}{\text{ second}}$

Therefore, the tire is turning 180 degrees per second.

It takes 2 seconds for the tire to make a full revolution. This is evident from the plot - the curve has a period of length 2.

A full revolution of the tire is a turn of 360 degrees.

So the tire turns at a rate of (360 degrees)/(2 seconds) = 180 degrees/second.

Which statement best describes the expression 3y ÷ 8?8 divided by 3 times y
8 times y divided by 3
3 divided by 8 times y
3 times y divided by 8

Answers

3 times y divided by 8

(the last answer)

Because "3y" comes first and then "÷ 8" so the order is correct with 3 times y divided by 8, and the others can be ruled out.

that would be b. because u have to calculate it in a caculater then it will show the answer

The only answer would be B. 8.8 would be in a sense where it repeats, but you don't have to write so many 8's. Your, in a way, paraphrasing the decimal.

Sophina brought 3 yards of trim to put around a rectangular scarf. She does not want the scarf to be wider than 12 inches or narrower than 6 inches .Using whole numbers , if she uses all the trim, what are the possible dimensions of her scarf in inches.

Answers

3 yards equal 108 inches you can split it in half and get 54 then see how many 12 go in to it and that would be 4 and there would be 6 left over. then we have 54 and see how many 6 can go into it then add 6 more then that would equal 10 6
so that means we would have four twelths and ten sixths
