Answer:12.5 seconds
Step-by-step explanation:hconsidering Runner 1 with a speed of 10m/s
and Runner 2 with a speed of 4 m/s
the equation of displacement for a uniform movement is
x=V*t
so x1=V1*t
and x2=V2*t
and the problem condition is x2=x1+75m
so we proceed to solve the equations.
from equation 2 t=x2/V2
substituting in equation 1 we have
x1=V1(x2/V2) and then the 3 equation
x1=V1((x1+75m)/v2
finally x1=75*(V1/(V2-V1)) =75*(10/(10-4))=125m
then t=(x1/v1)=125/10=12.5 seconds
10% of 35
First, we can assume that 35 is our '100' value.

Answer:
sin trigonometry ratio
Step-by-step explanation:
Given
See attachment for triangles
Required
Explain why 
From the attached diagram, both triangles are similar triangles because
(1) the second triangle is a dilation of the first triangle by a ratio of 1.5
i.e
(2) They have angle 30 degrees, and have their right angles located at the same point
In the first triangle, the sine of 30 degrees is represented as:
This gives:
In the second triangle:
So:
By comparison:
Hence:
Answer:
y=154
Step-by-step explanation:
y/7=22
We simplify the equation to the form, which is simple to understand
y/7=22
Simplifying:
+ 0.142857142857y=22
We move all terms containing y to the left and all other terms to the right.
+ 0.142857142857y=+22
We simplify left and right side of the equation.
+ 0.142857142857y=+22
We divide both sides of the equation by 0.142857142857 to get y.
y=154
The answer is C .This is because 4/5 is equal to 8/10. 9/10 plus 8/10 equals to 17/10 which is 1 7/10.Which is about 2 lb
