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>
Answer:
18 kilometers
Step-by-step explanation:
If each 1 cm represents 9 kilometers.
How many would 2 cm represent?
6)
80+160+100+8x+8+5x+10=540
13x + 358 = 540
13x = 540 -358
13x = 182
x = 182/13
x = 14
answer x =14
7)
7x+13=8x-8
8x-7x=13+8
x = 21
answer x = 21
