Answers

Answer 1

Answer: since Nilsa already used 20 mins on the test there are 40 mins left so
there are 40 mins and 8 questions left. 40/8 equals 5 so 5 mins is the greatest amount of time on average she can spend on each of the 8 remaining questions

Answer 2

Answer: Nilsa can spend at least 5 Minutes on each remaining question. Take 60 minutes - 20 minutes to get 40 minutes then divide by 8 questions to get 5 minutes / question

Answers

so basically since josh worked a fraction (that's less than 1) of staceys time then therefor stacy's tme is more than josh
josh<stacy
vicki worked a fraction(that's greater than 1) of stacey's time. since it is greater than 1, it makes it more so like 2 times 2 and 1/2=2+1=3 which is greater so
viki worked more than stacy therefor

josh<stacy<vicki
so
A is correct (Stacey>josh)
B is correct (Stacey<Viki)
C is false
D we have to solve by doing
4 and 3/4 convert to fraction improper
4 and 3/4=19/4
19/4 times 2/3=josh=38/12=19/6
viki worked 1 and 3/8 of stacey
19/4 times 1 and 3/8=19/4+57/32=209/32=7.9
josh+stacey=19/4+19/6=95/12=6.5
7.9>6.5 so
D is true

so the answers that are true are
A,B,D

2a is true and 2b is also true and 2c is false 2d is true

A running track in the shape of an oval is shown. The ends of the track form semicircles. A running track is shown. The left and right edges of the track are identical curves. The top and bottom edges of the track are straight lines. The track has width 68 m and length of one straight edge 140 m. What is the perimeter of the inside of the track?

Answers

two shapes.. a circle and a rectangle. The width of the rectangle serves as the diameter of the circle.

Length = 140 m ; Width = 68 m

Circumference of a circle = 2 π r
circumference of a cirlce = 2 * 3.14 * (68m/2) = 2 * 3.14 * 34 m = 213.52

length = 2 * 140 m = 280 m

perimeter of the oval = 213.52 m + 280 m = 493.52 m

Answer:

493.52
