You want to cover 56 inches, 8*7=56. It will cost $70 to cover the book.
Answer:
A. 11.33
Step-by-step explanation:
In the blue rectangle, the ratio of the height to the width is 21/34.
In the red rectangle, the ratio of the height to the width is 7/w.
We are told the ratios are equal, so we set the ratios equal and solve for w.
7/w = 21/34
Cross multiply.
21w = 7 * 34
21w = 238
Divide both sides by 21.
w = 238/21
w = 11.333...

Step-by-step explanation:
I used desmos graphing calculator to help me solve
Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes
600 words
90 words divided 15% is 6 words for 1% so 6 times 100 is 600
hope this helps!
