Answer:
25.12 meters
Step-by-step explanation:
The circumference of a circle is given by
(1)
where:
![\pi\sim 3.14](https://tex.z-dn.net/?f=%5Cpi%5Csim%203.14)
r is the radius of the circle
In this problem, the parachute has a diameter of 8 meters:
d = 8 m
The radius of a circle is equal to half of its diameter, so the radius of the parachute is:
![r=\frac{d}{2}=\frac{8}{2}=4 m](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%7D%7B2%7D%3D%5Cfrac%7B8%7D%7B2%7D%3D4%20m)
And therefore, by applying eq.(1) we can find the circumference of the circle:
![c=2\pi r=2\cdot 3.14 \cdot 4 = 25.12 m](https://tex.z-dn.net/?f=c%3D2%5Cpi%20r%3D2%5Ccdot%203.14%20%5Ccdot%204%20%3D%2025.12%20m)
So what are we trying to find the reduced fraction or inverse operation

Answer:
58
Step-by-step explanation:
The marked points on the graph show that the number of hot cocoas sold decreases by 6 when the temperature goes up by 6 degrees. That is, the line has a slope of -1. The y-intercept is 100, so the equation of the line can be written as ...
y = mx +b . . . . . line with slope m and y-intercept b
y = -x +100
Then for x = 42, the expected value of y is ...
y = -42 +100 = 58
Mei Mei can expect to sell 58 hot cocoas on a day when the high is 42°F.
Answer:
quadrilateral,parallelogram
Step-by-step explanation:
A quadrilateral is a four-sided polygon.
A parallelogram is a quadrilateral with two sets of parallel sides, much like a rectangle, but with no right angles.
