How you do this is using the formula speed = distance/time. So this is 100/5 which is 20 meters a second. Using the conversion factor (can google "20 meters per second is how many mile") 20 meters a second = 44.7 miles per hour.
In conclusion, the answer you're looking for is D. 44.7 miles per hour.
Answer:
1(left) goes with 1
2(left) goes with 3
3(left) goes with 2
4(left) goes with 4
Step-by-step explanation:
2(5+6) = 22
3(5+3) = 24
2(4+5) = 18
2(3+2) = 10
10 + 12 = 22
8+ 10 = 18
15 + 9 = 24
6 + 4 = 10
1(left) goes with 1
2(left) goes with 3
3(left) goes with 2
4(left) goes with 4
Answer: C. -1
Step-by-step explanation:
Answer:
1/28 of the sack
Step-by-step explanation:
First calculate the radius = 1/2 the diameter = [sqrt sqr160(4-0)^2 + (-14-(-2))^2] / 2
= (sqrt 160 ) / 2 so r^2 = 160 /4 = 40
center = midpoint of the diameter = (-14-2)/ 2 , (4+0)/2 = (-8, 2)
so required equation is (x + 8)^2 + (y - 2)^2 = 40
