Answer:
B
Step-by-step explanation:
K=1/3=10
L=1/5=6
10+6=16
30-16=14
Answer:
50%
Step-by-step explanation:
Actual value - estimated value
Actual value = 24 miles
Estimated value = 36 miles
Estimated value - Actual value
= 36 miles - 24 miles
= 12 miles
% error = change in value / actual value × 100
= 12/ 24 × 100
= 1/2 × 100
= 50%
% error = 50%
Answer:
2 1/5
Step-by-step explanation:
2 3/4 divided by 1 2/4=2 1/5
Answer:
7.5 Quarts
Step-by-step explanation:
D'Naisa mixed the following:
- 1 gallon of orange paint
- 2 quarts of yellow paint
- 3 pints of red paint.
We are to determine in total, the number of quarts of paint that she mixed. this is done by converting each of the volume to quart.
<u>1 gallon of orange paint</u>
- 1 gallon = 4 Quarts
- Orange Paint=4 Quarts
<u>3 pints of red paint.</u>
- 1 pint =0.5 quart
- 3 Pints =3 X 0.5 Quart
- =1.5 Quart of red paint
Therefore,
Total Volume of Paint Mixed in quart= Volume of Orange+Yellow+Red
=4+2+1.5
=7.5 Quarts
Given:
Area(A)= 63m^2
Length (L)= 2W+5
Width (W)=?
A=LxW
63=(2W+5)(W)
63=2W^2 + 5W
0=2W^2+5W-63
0=(2W-9)(W+7)
2W-9=0 then W=4.5 and W+7=0 then W=-7
Can only use 4.5 since it is positive and distance is positive.
W= 4.5 m
L=2W+5=2 (4.5)+5=9+5=14m
