Answer:
- perimeter: 36 +16√5 ft ≈ 71.777 ft
- area: 288 ft²
Step-by-step explanation:
<u>Perimeter</u>
The perimeter is the total length of all the sides. The length of the horizontal sides is 8 ft + 10 ft = 18 ft. The length of the slant sides can be found using the Pythagorean theorem. For side length s, we have ...
s^2 = 8^2 + 16^2
s^2 = 64 +256 = 320
s = √320 = 8√5
Then the perimeter is ...
P = 2(8√5 + 18) = 36 +16√5 ≈ 71.777 . . . feet
__
<u>Area</u>
The area is given by the formula ...
A = bh
where b is the base and h is the height.
A = (18 ft)(16 ft) = 288 ft²

Answer:
I can explain.
Step-by-step explanation:
4:5 is equal to 8:10 because your just multiply each number by 2.

5 x 2=10
Answer:
429/7 kg or 61 2/7 kg
Step-by-step explanation:
I'll answer according to how I understand this problem, but I'm not sure this is correct.
"39 kg of rice is taken out of bag of rice. If 8/22 of the rice is left, what was the original weight of the rice in the bag?"
8/22 is a strange number to work with because it could have been given as 4/11. This is another reason I'm not too sure about this problem.
8/22 = 4/11
If 4/11 is left, then since 11/11 - 4/11 = 7/11, 7/11 of the rice remains.
7/11 x = 39
x = 39 × 11/7
x = 429/7
x = 61 2/7
