Answer:
He can run 20 ft in 15 seconds
Step-by-step explanation:
we need to change yards to ft
3ft = 1yd
100 yds * 3ft/1yd = 300 ft
distance = rate * time
300 ft = rate * 15 seconds
divide by 15 seconds on both sides
300 ft/15 seconds = rate
20 ft/sec
He can run 20 ft in 15 seconds
Answer:
C
Step-by-step explanation:
let's say the 18 was the 100 and x was the 20% of that 100, if they equal the same just take 20% of 18 (you will get 3.6)
Therefore is C : x/18 = 20/100.
If the pieces are cut in the ratio <span>3:5:7</span>, the proportion of each piece to the whole (represented by <span>3+5+7=15</span>) is:
<span><span>3/15</span>:<span>5/15</span>:<span>7/15</span></span>
First, convert the inches to feet also:
1 foot equals to 12 inches.
So 9 inches <span>=<span>9/12</span>×1=0.75</span> feet.
Thus, 33 feet and 9 inches equal <span>33+0.75=33.75</span> feet.
So,
<span>P=<span>3/15</span>×33.75=6.75</span> feet.
<span>Q=<span>5/15</span>×33.75=11.25</span> feet.
<span>R=<span>7/15</span>×33.75=15.75</span> feet.
You can check that these answers are correct by adding up the different pieces: <span>6.75+11.25+15.75=<span>33.75</span></span>
