PLEASE HELP Find the surface area of the triangular prism.

Mathematics

1 answer:

ASHA 777 [7]3 years ago

4 0

Answer:

139

Step-by-step explanation:

First, find all the faces that you must find the areas of. In this case, you need to find the areas of two triangles and three rectangles.

In this triangular prism, the base is one triangle. If the area of the base is 7.75, we can assume that that holds true for both bases, and multiply 7.75 by 2 in order to find the area of both triangles.

Now find the area of each of the three rectangles by multiplying their individual heights and bases by each other. You should get 38, 47.5, and 38 as the areas of the rectangles.

Now add all the individual area's together. (They're bolded for clarity).

Answer:

Option A, no trend

Step-by-step explanation:

Since the points are all over the graph, that means that there is no trend.

If all the points followed a straight line toward positive infinity, it would be positive trend.

If all the points followed a straight line toward negative infinity, it would be negative trend.

Answer: Option A, no trend

162 short sleeve shirts; if you add 9 and 4, you get 13. Then, divide 234 by 13, which equals 18. 18 multiplied by 9 is 162.

HELPPP QUICK PLS I WOULD GIVE YOU THE BRAINIEST PLSSS HELPP MEEE BEFORE I HAVE A BREAKDOWN PLS What is the midpoint of a line se

Alisiya [41]

Answer:

(5.5, 12.5) OR (11/2, 25/2)

I would put in the decimal value as the answer, but of you like then you can add the fraction as an answer.

Step-by-step explanation:

We are given the endpoints (-4, 15) and (22, 3) to find the midpoint. In order to find the midpoint, we will use its formula.

Midpoint formula :- (x1 + x2 / 2, y1 + y2 / 2)

(x1 + x2 / 2, y1 + y2 / 2)

(-4 + 15 / 2, 22 + 3 / 2)

(11 / 2, 25 / 2) ---> (5.5, 12.5) Midpoint

Hope I answered your question. Stay safe, happy, and healthy, thank you :) !!
