30% can also be written as .3, which is easier to use in this case.
To find how many just sat around, multiply the number of people by the percentage of how many just sat around.
1400*.3=420
Therefore, (1/7)³ = 1/343, implying that the answer is option (D).
Hope it helps. :)
Answer:
300 sheets
Step-by-step explanation:
if you divide 35 by 7, you get 5
then divide 1,500 by 5 to get 300.
<span><span>L
* W = 300 sq ft
</span><span>
Length is 10 ft greater than twice the width.
L = 2W + 10
Substituting
(2W+10)*W = 300
2W^2 + 10W = 300
Divide both sides by 2
W^2 + 5W = 150
W^2 + 5W - 150 = 0
Factor
(W +15)(W -10) = 0</span></span>
<span>
<span>
Roots are W=-15 and W=10.
A negative width is impossible, so W=10
L = 2W + 10
L = 2(10) + 10
L = 30</span></span>
length = 30 feet, width = 10 feet
<span> Check:
30*10 = 300</span>
it would have to be the first one y=x+2
