You read 9.75 pages in your science book and 24.5 pages of a play for English class. It takes you 1.2 minutes to read each page
Kazeer [188]

Answer:

31.3 minutes were spent reading

Step-by-step explanation:

If it takes 1.2 minutes to read each page for science and you read 9.75 pages of science, then you must multiply these two numbers together

9.75 pages × 1.2 mins = 11.7

If it takes 0.8 of a minute to read each page of the play and you read 24.5 pages of a play, then you also multiplying these two numbers

24.5 pages × 0.8 mins = 19.6

If we must find out the time spent reading, we must add these two numbers together

11.7 + 19.6 = 31.3

You are going to make three shelves for your father and have one piece of lumber 20 feet long. Your plan is to make the top shel
cupoosta [38]

Answer:

The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet

Step-by-step explanation:

Let t= length of the top shelf, m = length of middle shelf and b = length of bottom shelf.

Therefore:

t = m - 1/2; m = t  + 1/2

Also, b = 2t - 1/2

The total of the three shelves is 20 feet, therefore:

t + m + b = 20

Substituting:

t + t + 1/2 + 2t - 1/2 = 20

4t = 20

t = 20/4

t = 5 feet

m = t + 1/2 = 5 + 1/2 = 5.5 feet

b = 2t - 1/2 = 2(5) - 1/2 = 9.5 feet

The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet
