Answer:
The speed rate is 100 feet per 25 seconds, or 20 feet every 5 seconds, (100 / 5 = 20)
Every minute is 60 seconds long, this means that to find out how fast she would roll in one minute we just need to do 60 / 5 = 12 and then do 12 x 20
12 x 20
10 x 20 = 200 feet per second
2 x 20 = 40 feet per second
200 + 40 = 240 feet per second
Happie would roll 240 feet in a minute at the speed of 100 feet per 25 seconds
Hope this helps!
Answer:
d=32!!!
Step-by-step explanation:
So first rewrite it as an equation: d/4+12=20
d/4+12=20 then subtract 12 from both sides to balance the equation
d/4=8 so multply both sides by 4 to isolate the variable, 4(d/4)=d =d and 8x4=32, so d=32

For every meter there are 3.281 feet. The perimeter of the yard is 188ft. Divide 188 by 3.281 and you get 57.3 (rounded to 1dp). Round that<em> up</em> to the nearest meter and you get 58. So, Mr Smith needs 58 meters of fencing for his yard.
