Answer:

4

Step-by-step explanation:

168 divided by 54 will give 3.1 with one forever and since you can't have a tenth of a bus you need 4

1. The cost of 4 hates is $29.68. What is the unit price?
OlgaM077 [116]

To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.

1. 29.68 / 4 = 7.42

So $7.42 is the unit price.

2. 625 / 6 = 104 (rounded to the nearest whole number)

So Jess can type 104 words per minute.

The base of a solid is the region in the first quadrant bounded by the line x=-2y+6 and the coordinate axes. What is the volume
nika2105 [10]

Answer:

V = \frac{4y^3}{3} -12y^2 +36 y \Big|_0^3

V= \frac{4(3)^3}{3} -12(3)^2 +36 (3) -0 = 36-108+108= 36

Step-by-step explanation:

For this case we have the following plot on the figure attached.

We know on this case that x = -2y+6 represent our radius for the square, since we need cross sections perpendicular to the y axis.

We find the intersection points like this:

x= 0 , y=3

y=0, x=6

Since we are assuming squares for the cross sections the area is given by A = r^2 where r = x= -2y+6.

Since our radius is on terms of x we can create a integral with limits on x in order to find the volume, And we can use the following integral in order to find the volume.

V = \int_{0}^3 (-2y+6)^2 = \int_{0}^3 4y^2 -24y +36 dy

On the left part we are using the following property from algebra:

(a+b)^2 = a^2 +2ab +b^2

(-2y+6)^2 = (-2y)^2 +2*(-2y)(6) +(6)^2 = 4y^2 -24y+36

And after do the integral we got this:

V = \frac{4y^3}{3} -12y^2 +36 y \Big|_0^3

V= \frac{4(3)^3}{3} -12(3)^2 +36 (3) -0 = 36-108+108= 36
