Answer:

Step-by-step explanation:

Perpendicular lines have related slopes. The slopes are negative reciprocals of each other. The slope of y=-2/3-4 is -2/3. So the perpendicular line will have slope 3/2. Y=3/2+1 is the solution.

Answer:

a. (3,11) (4,15) (5,19) (6,23)

b. it's not proportional because b (from y=mx+b) is not 0

c. the equation is y = 4x - 1

d. graph the y-int (-1) on the y-intercept and then connect the points in a.

What’s the volume of this

pav-90 [236]

Given:

The height of the cylinder = 12 in

The diameter of the base of the cylinder = 8 in.

To find:

The volume of the cylinder.

Solution:

The diameter of the base of the cylinder is 8 in. The radius is half of its diameter. So,

$r=\dfrac{8}{2}$

$r=4$

So, the radius of the base of the cylinder is 4 in.

The height of the cylinder, h = 12 in.

Base area of the cylinder is:

$B=\pi r^2$

Where, B is the base area and r is the radius.

$B=\pi (4)^2$

$B=16\pi$

So, the base area is $16\pi$ square inches.

The volume of the cylinder is:

$V=\pi r^2h$

$V=Bh$

Where, r is radius, h is height, B is base area.

Putting $B=16\pi$ and $h=12$ , we get

$V=(16\pi )12$

$V=192\pi$

So, the volume is $192\pi$ cubic inches.

Therefore, $r=4\text{ in}, h=12\text{ in},B=16\pi \text{ in}^2,V=192\pi \text{ in}^3$ .

molly works at an apple orchard.she picked 1,078 apples last weekend and put them into bags that hold 12 apples each.how many ba

kolbaska11 [484]

So 1078 total
12 each bag so
so divide 1078 by 12
1078 divided by 12=1078/12=89 and 10 left over (also 89 and 10/12=89 and 5/6)

she had 89 bags with 10 apples left over
