B, C, and D are true. 0.15price is 15% subtracted, 0.85 is with 15% subtracted, 420.75 is the sale price calculated.
Answer:
A = 81.681409 (81.64 for 3.14 as pi) B = 4.65222141 (4.65458109 as 3.14 for pi) rotations
Step-by-step explanation:
To figure out how far one full rotation is (which is the circumference) you do the circumference formula: C = 2 pi r
C = 2 pi 13
C = 26pi
C = 81.681409
To figure out how many rotations C can fit into 380, divide 380 by C
380 / 81.681409 = 4.65222141
Answer:
154 minutes to process and spell check 28 pages
Step-by-step explanation:
33 Minutes to process 6 pages
If we divide both of these numbers by 6 we will get the time taken to process 1 page
33 ÷ 6 = 5.5 minutes, and 6 ÷ 6 = 1 page
So 5 and a half minutes per page
To find out how long 28 pages will take, we multiply by 28
5.5 × 28 = 154 minutes, and 1 × 28 = 28 pages
Which gives us the time of 154 minutes to process and spell check 28 pages
This works because she added the number to she if she got right
