First thing you should do is simplify the question they are asking for the parameter and you know the parameter is two times the length plus two times the width.
2l + 2w = p
we know the only thing that is changing in this equation is the length and the perimeter
2(4w - 5) + 2w = 90 \\ l = 4w - 5

Sauron [17]

Answer: 12,620,256

Step-by-step explanation:

Given: The camera shop socks eight different types of batteries and there re at least 31 batteries of each type.

Here we want to select r= 31 batteries from n= 8 kinds of batteries, then formula we use to find number of ways is ^{n+r-1}C_r=\ ^{31+8-1}C_{31}

=^{38}C_{31}=\dfrac{38!}{31!(38-31)!}\\\\=\dfrac{38!}{31!7!}\\\\=\dfrac{38\times37\times36\times35\times34\times33\times32\times31!}{31!\times5040}\\\\=12620256

Hence, the number of ways can a total inventory of 31 batteries be distributed among the eight different types = 12,620,256

A runner, training for a competition, ran on a track every day for 10 weeks. The first week he ran 8 kilometers each day of the
Levart [38]

Answer:

Total = 686000 meters for 10 weeks 7 days a week.

Step-by-step explanation:

Let's solve this by doing the increase on just 1 training day per week. Then we can find the grand total for 7 days a week by multiplying by 7

a = 8000

n = 10

d = 400

Sum = (a + L)*n/2

  • L = a + (n - 1)*d
  • L = 8000 + (10 - 1)*400
  • L = 8000 + 9*400
  • L = 8000 + 3600
  • L = 11600 meters

Sum = (8000 + 11600)*10/2

Sum = 19600 * 10/2

Sum = 98000 meters.

This total represents 1 training day a week.

The total amount is 7 times this figure.

Total = 7 * 98000 = 686 000 meters.
