Math problem for high school

Answers

Answer 1

Answer:

50/3

Step-by-step explanation:

area of triangle = 10

area of circle = 10

area of triangle + area of circle = 20

The white sector of the circle has central angle 60°.

Its area is 1/6 the area of the circle.

To find the gray area, you must subtract the white area from the area of the circle and also subtract the white area from the area of the triangle. Two times the white area is 1/3 the area of the circle.

gray area = 20 - (1/3)10

gray area = 20 - 10/3

gray area = 60/3 - 10/3

gray area = 50/3

Answer 2

Answer:

The white sector of the circle = (1/6) (10) = 10/6 = 5/3

So....the grey area = 10 + 10 - 2 (5/3) = 20 - 10/3 = 60/3 - 10/3 = 50 / 3

Rectangle A and Rectangle B are similar. Rectangle A has side lengths of 16 and 8. Rectangle B has a side length of 32. What are the possible values for the length of the other side of Rectangle B? Select all that apply.

12
16
38
64

Answers

Triangle A and triangle B have a Similarity coefficient equal to 2 (32/16)

If 32 is the largest side therefore the other side is 16

If 32 is the smallest side so another side is 64

Answer : 16, 64

Answer:

16，64

Step-The side with a side length of 32 may be the long side or the short sideby-step explanation，so there are two cases：

1、the long side: 16/8=32/X，X=16

2、the short side：16/8=X/32，X=64

Reduce the fraction by the highest number 64 and 1000 go into. (which is 8)

So it'll turn into [tex]\sqrt[3]{\frac{8}{125} }[/tex]

Then reduce the fraction again, which will leave you with [tex]\frac{2}{5}[/tex]

Therefore, x= 2/5

Reduce the fraction using 27.

That will give you [tex]x^{3} = \frac{1}{8}[/tex]

Then simplify the equation, which will give you [tex]x=\frac{1}{2}[/tex]
