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

Answer 1

Answer: 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

Answers

so this wants you to add the fractions and subtract 1/1

we know that 6/8=3/4 because 3/4 times 2/2 (or 1) os 6/8

so we need the denomenators (bottom number) to be the same

so 5/6=10/12
1/4=3/12
2/3=8/12
add them together
10+3+8=21
21/12=1 and 9/12
subtract 1 and get
9/12 left or 3/4 yard left

Kevin spends $11.25 on lunch every week during the school year. If there are 35.5 weeks during the school year, how much does Kevin spend the entire school year?Remember to round to the nearest penny.

Answers

First, you multiply. You get $399.375. when you round it to the nearest penny, look behind the decimal, see if it's going down to 0, or going higher than 5, then round. the overall answer is going to be..............$399 and 40 cents.

Lunch per week times weeks total
11.25×35.5=399.375
rounded to the nearest penny is the same as the hundredths place which is $399.38 since the next decimal place is 5 or more
