Answer:
142.24cm
Step-by-step explanation:
If 100 inches = 254cm then if you do 254/100 you will get how many cm are in an inch. 254/100 = 2.54
This means there are 2.54 cm in an inch. Multiply 2.54cm by 56 inches and you get how many cm are in 56 inches which is 142.24cm. This means Elena is 142.24 cm tall.
I think it might be (B), not for sure but it has to be (B)
Answer:
79.4 m
Step-by-step explanation:
In this problem we deal with a right triangle with hypotenuse 90 m. We are told that tan Ф = 15/8; 15 represents the vertical distance of the kite off the ground and 8 represents the horizontal distance from the kite flyer to the kite. This is sufficient info from which to determine the angle of elevation from kite flyer to kite: tan Ф = 15/8 yields Ф = 1.08 radians.
Using this same angle Ф = 1.08 radians, sin Ф = (vertical distance) / hypotenuse = sin 1.08 rad = 0.882.
Then the vertical distance (height of the kite) is
(90 m)(0.882) = 79.4 m
N÷3+1 or can be stated as 3÷n+1
