Divide the fathers height by the percentage:
180/ 1.2 = 150
Allister is 150 cm tall
A simple way you could solve this is by drawing a tape graph.
Draw a long rectangular box.
Cut the box into 8 pieces, seeing as how 5/8 of the coins are dimes.
We have to take 48 and divide it by 8, we get 6, so now we know how many dimes are evenly split into each piece.
Now color in 5 pieces of the tape.
This represents the 5 in 5/8.
Now to find the number of coins, simply multiply 5 by 6, you get the answer of 30.
I hope this helps, if you are confused with any part of my explanation, ask and I will clarify.
Oh. I thought you meant 3-6, not questions 3 through 6. Sorry :(
Answer:
this is the closest i can get to the answer
1. 0.33/1 = 0.33
2. how much it costs per ounce
3. it represents the facts that it costs 0.33 per ounce
4. y=0.33x+0.33
sorry if it's wrong
Use half the fencing in each direction: 3 segments in one direction, 2 in the other.
<span>W * L = 24 million </span>
<span>3 W = 2 L </span>
<span>W * 3 W / 2 = 24 million </span>
<span>W^2 = 16 million </span>
<span>W = 4000 </span>
<span>L = 6000 </span>
<span>This shortcut (3 W = 2 L) </span>
<span>is derived from total fencing = 3W + 2L </span>
<span>and W*L = 24 million </span>
<span>total fencing = 3W + 2 * 24 million / W </span>
<span>and taking the derivative, setting to 0, and solving for W</span>
