Answer:

72 novels

Step-by-step explanation:

A number of assumptions are involved regarding operating environment, utilization fraction, and probability of failure as a function of time. The precise meanings of the words "average", "supposed to last", "maximum", and "expect" are involved. The details are too arcane to go into here.

 (450 hours)/(6 1/4 hours/novel)

 = (450/(25/4)) novels

 = (450*4/25) novels

 = 72 novels

In a poll, 6 out of 13 children said they read every night before bed, whereas 54% of the adults said they read every night befo
Tpy6a [65]
To answer this question you must find the percentage of the children that read before bed and compare it to the adults bag read before bed’s percentage.
To do this, start by dividing the number of children that read before bed by the total number of children surveyed.
This leaves you with:
6/13= 0.4615

To find the actual percentage, multiply this result by 100.
0.4615 x 100 = 46.15
This percentage rounded is 46%

So, now you can compare the percentages. The percentage of children that read before bed is 46% and the percentage of adults that read before bed is 54%. So, the group with the greatest percentage was the adults.

I hope this helps!

jenny wants to buy a winter coat for $200. the store advertises that customers can take 25% off the original price and then take
777dan777 [17]
Hello!

Let's check:

200 * 25% = 50

200 - 50 = 150

150 * 10% = 15

150 - 15 = 135

So, with the 25% and then an extra 10% off, the coat would cost $135.

200 * 35% = 70

200 - 70 = 130

So, Jenny's friend is incorrect, because that is not the same as a 35% discount.

Find the total amount of money​ (maturity value) that the borrower will pay back on a loan of ​$1 comma 760 at 13 and one half %
bagirrra123 [75]

Answer:

The borrower will pay back $4,136.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P.

In this question:

Loan amount of 1760, so P = 1760

Interest rate of 13 and one half, so 13.5%. This means that I = 0.135.

10 years, so t = 10

Interest on the Loan:

E = P*I*t = 1760*0.135*10 = 2376

Total amount:

T = E + P = 2376 + 1760 = 4136

The borrower will pay back $4,136.
