Answer:
Volume = 434.89
Step-by-step explanation:
Answer.
Solve the problem yourself first, to see if Pedro made any mistakes.
4/7 x 8/5
4x8 = 32
7x5 = 35
32/35 is the answer.
Pedro made his error in step 2, he cross multiplied instead of multiplying the numerators, and then the denominators.
Answer:
75feet
Step-by-step explanation:
To measure a stone face carved on the side of a mountain, two sightings 700 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 35 and the angle of elevation to the top is 38 , what is the height of the stone face?
Iet us say we have two right triangles. With a base of 700. The first has angle of 35o and the other has an angle of 38degree
Then we need the Height
From trigonometry
Tan = opposite/adjacent.
In this case the adjacent is 800
Tan 35 = 0.7002
Tan 38 = 0.781
Answer:
A, B, C and F
Step-by-step explanation:
We have according to the options:
A.
B.
C.
D. , which is not rational.
E. , which is not rational.
F.
Hence, the expressions representing rational numbers are A, B, C and F.
The unit rates are: 100 words in 5 minutes and 20 words per minute, and that is because usually when we want to find the rate of something, we do it by time.
