45 divided by 50= 90%
0.9*16.50=14.85
Answer:
2
Step-by-step explanation:
We need to plot the points in a graph and see the general shape of the curve.
<em>Attached is the graph.</em>
<em />
This Upside Down "U" shaped curve is that of a parabola, which has the general form
Thus, we see, the function is a 2nd degree function, highest power is 2.

You can do this by converting this into a ratio or a fraction
Ratio:
1 lb for 4 guinea pigs
1:4
If he was 8 lbs for x guinea pigsit would be
1:4
8:x
Multiply the first ration until the one is equal to 8, then whatever the four turns into is x
Fraction: (easier way)
1/4 (1lb for 4 guinea pigs)
8/x (8lb for x guinea pigs)
1/4 = 8/x
Multiply one until it is equal to 8
Correspond that to the 4
1*8 = 8
4*8 = 32
32 guinea pigs
4.5 is the answer because
first I took out the decimal which the new number is now 13
13÷3=4R1( I divided it by 3 because 1 yard=3 feet)
now the reminder is 1.5 which equals 18inches and 1 yard equals 36 inches
and now since 18 is 1/2 of 36
1/2 in decimal form is 0.5 or.5
so now the answer is 4.5
