Answer:
the proportion is 0.2779, that is a 27.79%
Step-by-step explanation:
The article reported that 1880 children ate fast food from a sample of 6765 children. We can use the rule of three to find the proportion of children that ate fast food
- from 6765 we have 1880 children that ate fast food
- from 100 children we have
children that ate fast food
that gives us that a 27.79% of the children ate fast food on a typical day. We can obtain the proportion by dividing the percentage by 100, that gives us a proportion of 27.79/100 = 0.2779.

Break up the problem into two parts: 1) find the surface area of the sides of the cylinder and 2) find the surface area of the top or bottom and multiply your result by 2.
Part 1: Imagine that you cut the side of the cylinder parallel to its axis once and then open up this shape to form a rectangle. The length of this rectangle is equal to the circumference of the cylinder times the height/length of the cylinder parallel to its axis: A1 = 2 pi (7 units) (3 units), or 42 pi square units.
Part 2: The total area of the two ends of the cylinder is 2 (pi [7 units]^2), or 98 pi square units.
Add these two areas together to get the total surface area of the cylinder.
Answer:
-1
Step-by-step explanation:
1+4.5x+4.9x=-8.4
4.5x+4.9x=-8.4-1
9.4x=-9.4
x=-9.4/9.4
x=-1
Answer:
im trying to figure out the answer sorry if take long :( bumb
19/25 = x/100
Cross multiply:
1,900
Divide 1,900 by 25
Equals 76
Subtract 76 from 100
Answer: 24% change
I hope this helps!
