For volume of a prism, the general rule is multiply the area of the base by the area of the height. For example, for a triangular prism, the volume would be (1/2)b*h*a if you set a = height of the prism and h = height of the triangle from the formula (1/2)bh, which is the area of a triangle.
90. The original cost of a camera of a camera is 150 dollars, Now it decreased into 65 dollars.
Let’s solve for the percent of decreased in the price of the camera.
=> 150 = 100%
=> 65 / 150 = .43
=> .43 * 100% = 43%, 65 = 43% of the amount
=> 100% - 43% = 57%
Thus, the price of the camera decreased for about 57% of the original price and now only costs 43% of the original price.
Answer:
Step-by-step explanation:
The bottom leg is divided into equal segments, one of them is b.
It means the bottom leg is b + b = 2b.
<u>According to Pythagorean:</u>
<u>Solve for b:</u>
- 1681 = 4b² + 81
- 4b² = 1681 - 81
- 4b² = 1600
- b² = 400
- b = √400
- b = 20 cm
Answer:
m<HGF = 45
Step-by-step explanation:
This picture shows an inscribed angle. It is made of 2 chords that connect on the vertex.
An inscribed angle is equal to half the arc. It is the arc that the angle makes. In this case it is the arc HF. So, to find the answer you would divide the length of arc HF by 2.
90/2=45
