Jammal makes a cut through a block of florist's foam, as shown. What are the dimensions of the exposed cross section?
Ahat [919]

Answer:

C. 3 in x 6 in

Step-by-step explanation:

Jammal cuts the block in a straight line parallel to one side... so the section revealed when he finishes his cut will be identical as the parallel side to which the cut is done.

We know the the left side of the prism on the image is 3 inches wide and 6 inches high... so that will also be the dimensions of the exposed cross section.

The answer is then 3 inches y 6 inches. The thickness of the block (5 inches) has no impact on the exposed area of the cross-section.

Help asap!! interpret the meaning of the expression
Triss [41]

Answer:

D

Step-by-step explanation:

This is exponential growth, and to my understanding, the format goes:

<em>initial amount (percent growth/ decay)^time</em>

percent growth = (<em>decimal percent + 1)</em>

<em>percent decay = (1 - decimal percent) </em>

Your equation:

1500(1.02)^t

Using the above format, 1500 appears to be the initial amount, which increases by 2% per annum.

Michael drives to work and home from work each workday. He travels a total of 160 miles at the end of the workweek. How far is M
sdas [7]

Answer:

Michael's house is 16 miles away from work.

Step-by-step explanation:

We are given the following in the question:

Total distance traveled by Michael at the end of the workweek = 160 miles.

Let x miles be the distance between Michael's house from work.

Thus, total distance covered in one day =

2x\text{ miles}

Total distance covered in one weekday(5 days) =

2x\times 5 = 10x\text{ miles}

Equating,

10x = 160\\\Rightarrow x  = 16

Thus, Michael's house is 16 miles away from work.

Say a business found that 98.3% of soda cans at a production facility in California are filled correctly. The company chooses 10
Shtirlitz [24]

Answer:

The events must be independent.

Step-by-step explanation:

The only assumption that must be made is that the events are independent. That is, the amount of soda in a given can does not depend on the amount of soda of any previous can filled at the same facility.

If this assumption holds, then the probability of finding exactly k cans of soda filled correctly would be

\displaystyle\binom{100}{k}(0.983)^k(1-0.983)^{100-k}

where

\displaystyle\binom{100}{k}=\displaystyle\frac{100!}{k!(n-k)!}

are combinations of 100 elements taken k at a time.
