I need help with letter C, find the area

Mathematics
1 answer:
ElenaW [278]3 years ago
5 0

Answer:

x = 38

Step-by-step explanation:

Here, we can use the area formula A = 0.5(Bh) to solve for x.

In this case, A = 399, B = x, and h = 21

399 = \frac{21}{2} x\\x = \frac{2*399}{21} \\x = 38

Suppose you plan to fence in an area where your dog can exercise without getting into the street. The length will be 3 times the
Reptile [31]

Answer:

The width of the equation is 3 and the length is 9

Step-by-step explanation:

This problem was kind of simple for me to answer. The first thing I did was divide the 4 sides of the perimeter into  sections which would bring me to find that it was 6 inches on each side then I divided that by 2 bringing me to the answer of 3. Then I decided to multiply 3 by 3 which brought me to the answer 9. I decided to try it around the perimeter which would be....

9+9+3+3=?

I added the 9's first which gave me 18 .Then added the 3's together which gave me 6. The final step I added 6 and 18 together and got 24.

Giving the fact that the length is 3 times greater than the width I came to the conclusion that....

3 is the width and 9 is the length.

3/4h-9=1/4h-1 i need help
Vlada [557]

<u> Answer I got for this was 16.

Subtract the 1/4 from the 3/4 and get 2/4, simplified: 1/2

You should have 1/2 h -9 = -1 by now,
Then add nine to the other side, getting 8.
You should have 1/2 h = 8.
Then divide 1/2 by 8.
8/1÷1/2 ---> 8/1 × 2/1 (you flip the fraction when you divide)
So your answer is 16!
Hopefully that helped!</u>

The following question has 2 parts. First, answer part A. Then, answer part B.
aalyn [17]

The fraction that represents the addition model shown above will be 53/100.

<h3>How to solve the fraction?</h3>

From the information given, a grid with 10 equal columns is shown with 5 shaded in. This will be expressed as 5/10.

Also, a second grid is shown, identical in size, containing 100 squares with 3 shaded in. This will be expressed as 3/100.

Therefore, the problem that represents the addition model shown above will be:

= 5/10 + 3/100

= 50/100 + 3/100

= 53/100

In this case, the answer given by Emma is incorrect as he added 5 to 3 and got 8/100.
