Find the surface area of a triangular prism with the dimensions of 14 16 and 18

Answers

Answer 1

Answer: To find the height of the triangle we can use pythagorean theorem or a squared to b squared = c squared with c as the hypotenuse.

14 squared + height squared = 16 squared
196 + height squared = 256
height squared = 60
height = 2 $√(15)$

The formula for surface area or total area is:
perimeter x height + 2 x area of base
30 + 2 $√(15)$ + 28 $√(15)$
30 + 30 $√(15)$ = final answer

Hopes it helps!

A telephone company charges a fixed monthly rate plus a rate per megabyte of data used. The company charges $155 for 100 megabytes and $245 for 200 megabytes. An equation can be written to show the relationship between the total megabytes of data used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph? Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 0.9 Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 1.1 Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 1.1 Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9

42 divided by 6 in repeated subtraction

Answers

42 - 6 = 36 - 136 - 6 = 30 - 230 - 6 = 24 - 324 - 6 = 18 - 418 - 6 = 12 - 512 - 6 = 6 - 66 - 6 = 0 - 742/6 = 7

42-6=36
36-6=30
30-6=24
24-6=18
18-6=12
12-6=6
6-6=0

Write two expressions that are equivalent to 6(m + 2 + 7m)

Answers

Hey there!

You could $\bold{distribute}$ " $\bold{6}$ " into your terms

$\bold{6(m+2+7m)}$
$\bold{6(m)=6m}$
$\bold{6(2)=12}$
$\bold{6(7m))=42m}$

Next, you have to $\bold{combine}$ your $\bold{like-terms}$

$\bold{6m(and)42m}$
$\bold{12}$

$\bold{6m+42m=48m}$
The " $\bold{12}$ " stays the same since it doesn't have a like term in this equation
$\bold{\rightarrow48m+12}$

$\boxed{\boxed{\bold{Answer:48m+12}}}\checkmark$

Good luck on your assignment and enjoy your day!

1,200, 3.5%, 2 years

Answers

Answer:

Step-by-step explanation:

If you want to find the compound interest you turn 3.5% into a decimal. Before this add 100% which is now 103.5% which is 1.035. Now you put this to the power of 2 and multiply by 1200. Put this into your calculator as 1.035^2x1200.

Which statement is true about the graphs shown? A) Only graph A represents a proportional relationship. B) Only graph B represents a proportional relationship. C) Graph A and graph B both represent a proportional relationship. D) Graph A and graph B both represent a non-proportional relationship.

Answers

Answer:

I believe the answer is B.

Step-by-step explanation:

Because a proportional relationship is one where x is proportional (equal) to y, and Graph A does not fall into that category, and Graph B does, the answer should be B.

Answer:

The answer A

Step-by-step explanation:

Only graph A represents a proportional relationship.

Two quantities are proportional to each other if the graph is a straight line through the origin.
