Answer:

B.) 3√15

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 11^2 = 16^2

x^2 + 121 = 256

x^2 = 256 - 121

x^2 = 135

√x^2 = √135

√135 = √9 • √15

√9 = 3

√15 = √15

3√15

Write an equation to represent the number of pages Jesse has read. Using x, the number of days Amir has been reading, write an e
katrin [286]

Question:

Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.

How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?

Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.

Answer:

It will take 6 days

Step-by-step explanation:

For Jesse:

Rate = 30\ pages/day

This implies that Jesse will cover 30y in y days

For Amir:

Rate = 35\ pages/day

This implies that Amir will cover 35x in x days

Because Amir starts a day later,

y = x + 1

So, we have the following equations:

Jesse = 30y

Amir= 35x

y = x + 1

To get the number of days when they read the same number of pages, we have:

Jesse = Amir

Substitute values for Jesse and Amir

30y = 35x

Substitute x + 1 for y

30(x+1) = 35x

Open bracket

30x+30 = 35x

Collect Like Terms

30 = 35x-30x

30 = 5x

Solve for x

\frac{30}{5} = \frac{5x}{5}

\frac{30}{5} = x

6 = x

x = 6

A cube number is rolled 20 times and lands on 1 two times and on 5 four times. Find each experimental probability. Then compare
kykrilka [37]
The experiment probabilities are listed below:

One:  2 out of 20 = 2 / 20 = 0.1  or 10%

Four:  5 out of 20 =  5 / 20 = 1 / 4 = 0.25 = 25%

The theoretical probability of any single number is 1 out of 6 or about 17%.

The experimental probability for ones was less than and for fours it was greater than the theoretical probability.
