Answer:

The width is 4 meters

Step-by-step explanation:

The area of a rectangle is

A = l*w

We know the area and the length

28 = 7*w

Divide each side by 7

28/7 = 7w/7

4 =w

What is the surface area of this right rectangular prIsm?
uranmaximum [27]

Answer:

28

Step-by-step explanation:

To find the area of a rectangle we multiply two edges together.

since we are looking for the surface area we are actually going to be finding 6 different areas and adding them together (since there are 6 sides to a rectangle)

ok so sides 1 and 2, the edges on the left and right will be equal, and then the four sides in the middle are all going to be equal

2(1x2) + 4(3x2) = 4 + 24 = 28

In ΔVWX, the measure of ∠X=90°, WX = 8.3 feet, and XV = 2.5 feet. Find the measure of ∠W to the nearest tenth of a degree.
kiruha [24]

Answer:

16.76°

Step-by-step explanation:

In ΔVWX, the measure of ∠X=90°, WX = 8.3 feet, and XV = 2.5 feet.

We want to find the measure of <W.

We know side length that is adjacent and opposite to <W.

We can use the tangent ratio, to find the measure of <W.

The tangent ratio is opposite over hypotenuse.

\tan(m \angle \: w)  =  \frac{2.5}{8.3}

\tan(m \angle \: w)  =  0.301

Take tangent inverse to get:

m \angle \: w= { \tan}^{ - 1}   (0.301)

m \angle \: w=16.76  \degree

Dvinal [7]

Answer:

t+0.07t=t(1+0.07)=t(1.07)=1.07t

Step-by-step explanation:

There are a couple of  equivalent expressions to the function t+0.07t. For example:

t+0.07t

Factor:

t+0.07t=t(1+0.07)

If you add the terms inside the parentheses:

t(1+0.07)=t(1.07)

Basically you can add the like terms from the start and get the same result.

t+0.07t=1.07t

Therefore:

t+0.07t=t(1+0.07)=t(1.07)=1.07t
