Answer:
8
Step-by-step explanation:
We have, 25% × x = 200
or,
25
100
× x = 200
Multiplying both sides by 100 and dividing both sides by 25,
we have x = 200 ×
100
25
x = 800
If you are using a calculator, simply enter 200×100÷25, which will give you the answer.
So now that you have the original number you just need to find 1% of 800
1% of 800 is 8
See the attached picture:
I don't really understand this...
As the three longitudinal lines are parallel:
angle 4 = 5 = 6 = 82 degree (corresponding angles) = 9 = 8 = 7 = 82 degrees (vertical angles)
and
angle 11 = 180-82= 98 degrees (linear pair)
so:
angle 10 = 11 = 12 = 98 degrees (corresponding angles) = 3 = 2 = 1 = 98 degrees (vertical angles)
.
hope you got it
Answer:
![114.8\ ft^{2}](https://tex.z-dn.net/?f=114.8%5C%20ft%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of a trapezoid is equal to
![A=\frac{1}{2}(b1+b2)h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%28b1%2Bb2%29h)
In this problem we have
![b1=12\ ft](https://tex.z-dn.net/?f=b1%3D12%5C%20ft)
![b2=15\ ft](https://tex.z-dn.net/?f=b2%3D15%5C%20ft)
----> the height of the trapezoid is the perpendicular distance between the bases
substitute the values
![A=\frac{1}{2}(12+15)(8.5)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%2812%2B15%29%288.5%29)
![A=\frac{1}{2}(27)(8.5)=114.75\ ft^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%2827%29%288.5%29%3D114.75%5C%20ft%5E%7B2%7D)
Round to the nearest tenth
![114.75=114.8\ ft^{2}](https://tex.z-dn.net/?f=114.75%3D114.8%5C%20ft%5E%7B2%7D)
