Answer:
Option B. 7.6
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
where
k is the constant of proportionality
The slope of the linear equation is the same that the constant of proportionality
In this problem we have

so
the slope is 
therefore
The constant of proportionality k is 
Answer:
207 minutes.
Step-by-step explanation:
115 x 4/5 = 92
115 + 92 = 207
I believe the answer is side GF .
Answer:
1) 59.7 2) 7.1
Step-by-step explanation:
1)The diameter of a circle is 19 m. Find the circumference to the nearest tenth
The equation to find the circumference for a circle is C=2πR or C = πD. The diameter is equal to 2r so that is why the equation works either way. Now we will plug in the numbers. C =19π. This is approximately equal to 59.6902604182 which is approximately equal to 59.7
2)AND the diameter of a circle is 3ft. Find its area to the nearest tenth.
As stated before the diameter is equal to 2r. The area of a circle is calculated using the equation πr^2. First we need to find the radius which is 1/2D. 3/2 = r or 1.5 = r. Now we can plug all values in. A = π1.5^2 which equals to 2.25π which equals to 7.06858347058 which is approximately 7.1.
