Multiply 4and 25 then get the sq rt of 100 = 10
Answer:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:
The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the sun
I you use 1/6 of the bag for 1/2 a pound then you need to set up a proportion.
1/6 bag / 1 bag = 1/2 pound / x pounds Cross Multiply
(1/6)*x = 1/2 pounds * 1 bag Divide by 1/6
Remember: in a 4 level fraction, the denominator inverts and multiplies.
x =

3 pounds <<<<
answer
The correct answer is the last choice.
