Answer:
About 13
Step-by-step explanation:
There's no equation shown, but you can guesstimate and say it's between 10 and 20, so about 13 makes sense
The concept that can be used in order to answer this item is that of man-days. The total number of man-days required to do the job should always be constant.
This can be illustrated by the givens above.
Scenario 1:
N1 = (4 employees)(4 days) = 16 man-days
Scenario 2:
N2 = (2 employees)(8 days) = 16 man-days
The equation for determining the value of e is equal to,
k = (d)(e)
The answer is the second choice.
Answer:
Rectangle, trapezoid, quadrilateral
Step-by-step explanation:
The quadrilateral is a parallelogram with perpendicular diagonals
The volume of a rectangular prism is its length times width times height, or algebraically,

. You may be used to computing volume with numbers, but remember, a variable is a stand-in for a number. So you can solve this in the same way. Substitute

into the formula for volume. You get

, and you multiply these factors together. As you would with ordinary fractions, multiply the numerators and denominators across. You get

. It seems that the book wants you to simplify by bringing the 6 up to the denominator. Recall the rule

, if n is non-negative. The opposite applies so that

. For your final answer, you write

. This corresponds to
answer choice B.
