since it is the distance up to 3 hours
35 *3 = 105
but the student is counting by 10's so it should be 110
Idk exactly what those angles are called. I think supplementary interior. Which means they add up to 180°
So, (4x-2)+(6x-8)=180
Simplify. 10x-10=180
Now we need to get x by itself so add 10 to both sides to get 10x=190
Then divide by 10 to get x by itself x=190/10
So x=19
Hope this helped!!!
The correct answer is 26%
<u>Answer:</u> She misses 56 times at a soccer practice.
<u>Step-by-step explanation:</u>
Let the goals she misses be 'x'.
According to the question:

These two ratios follow direct relationship, so:

Hence, Vonna misses 56 times at a soccer practice.
The two parabolas intersect for

and so the base of each solid is the set

The side length of each cross section that coincides with B is equal to the vertical distance between the two parabolas,
. But since -2 ≤ x ≤ 2, this reduces to
.
a. Square cross sections will contribute a volume of

where ∆x is the thickness of the section. Then the volume would be

where we take advantage of symmetry in the first line.
b. For a semicircle, the side length we found earlier corresponds to diameter. Each semicircular cross section will contribute a volume of

We end up with the same integral as before except for the leading constant:

Using the result of part (a), the volume is

c. An equilateral triangle with side length s has area √3/4 s², hence the volume of a given section is

and using the result of part (a) again, the volume is
