Mike can build a go cart in 30 days, Jed can build one in 20 days and Erick in 60 days. If all of them share the work, how quick

Gwar [14]

Answer: 10 days

<u>Step-by-step explanation:</u>

Mike: $\frac{x}{30}$

Jed: $\frac{x}{20}$

Erick: $\frac{x}{60}$

Together: $\frac{x}{30}$ + $\frac{x}{20}$ + $\frac{x}{60}$ = 1

60 $(\frac{x}{30}$ + $\frac{x}{20}$ + $\frac{x}{60}$ = 1)

2x + 3x + x = 60

6x = 60

x = 10

You and your friend are in a canoe race. Your friend is a half mile in front of you and paddling 3 miles per hour. You are paddl

julsineya [31]

Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.

b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.

Finger [1]

They are two triangles faces that are (6x2)/2 = 6 and the other one is 6 to

so that's 12

the top side is 4 x 2 = 8

back side is 3 x 2 = 6

the bottom side is 2 x 6 = 12

so its 12 + 8 + 6 + 12 = 36 inches squared surface area
