Today 2/5 of the remaining students gave their speech. That’s 12 more

So a total of 27 students gave their speeches. That means 18 students remain. The answer is 18

8. The volume of the pyramid is 168 cubic inches. Find the length of the rectangular base. (3pts)7 inI8 in.
olya-2409 [2.1K]

The length of the rectangular base is 9in

<h3>How to determine the value</h3>

It is important to note that the formula for determining the volume of a pyramid with rectangular base is expressed as;

Volume = lwh/3

Where;

  • l is the length of the rectangular base of the pyramid
  • w is the width of the rectangular base of the pyramid
  • h is the height of the rectangular base of the pyramid

Given the value of the volume, width an height of the pyramid as 168, 7 and 8, we substitute the values, we have;

168 = l × 7 × 8/ 3

cross multiply

l × 7 × 8 = 168(3)

Find the product

56l = 504

To determine the length, divide both sides by 56, we get;

l = 504/ 56

l = 9In

Hence, the value is 9in

If i read 60 pages in 1 5/12 hours how long will it take me to read 120 pages
zysi [14]

Answer:

Step-by-step explanation:

Direct proportion

60: 1 5 /12 = 120 : x

60: 17/12 = 120:x

Product of extremes = product of mean

60*x = (17/2)*120

60*x=\frac{17}{12}*120\\\\60*x=17*10\\\\x=\frac{17*10}{60}\\\\x=\frac{17}{6}\\\\x=2\frac{5}{6}

It will take  2 5/6 hours to read 120 pages
