A) volume equals = length x width x height

2.8m is the height

1.2m is the width

4.8m is the length

so 2.8m x 1.2m x 4.8m = 16.128m³ is your answer

b)1 cubic meter is 1000

2.8m = 2800L

1.2m = 1200L

4.8m = 4800L

so your going to add those up

2800L + 1200L + 4800L = 8800L is you answer

Answer: 5

Steps:

5x - 2y = 30

5(8) - 2y = 30

40 - 2y = 30

-2y = 30 - 40

-2y = -10

y = -10/-2

y = 5

I would appreciate the brainliest if this answer was correct and the steps were clear and helpful! :)

**Answer:**

13

**Step-by-step explanation:**

a parallelogram has sides that are parallel to the opposite side. This means that y + 7 is going to be parallel to 20.

Two opposing sides of a parallelogram are parallel and **equal**

You know that the length of both of the sides is equivalent because the other set of opposing lines is also parallel (you can think of it as cutting off the line segment of y+7 and 20 at the same length. )

this means that we can set up the equation to find y as:

y + 7 = 20

then, you can proceed to find y by isolating it:

y + 7 = 20 ; so therefore

y + 7 = 20

- 7 -7

y = 13

y = 13

So, the value of y is 13

Answer:

B. AA

Step-by-step explanation:

The diagram given shows that two angles in ∆ABC are congruent to two corresponding angles in ∆STU.

Invariably, the third unknown angle of both triangles would also be equal going by the third angle theorem.

Thus, based on the AA Similarity Theorem which says that two triangles are similar to each other if two corresponding angles of one is congruent to two angles in the other, ∆ABC ~ ∆STU.
