9 - x &lt; - 11<br> Show steps please
mihalych1998 [28]

Answer: x > 20

Step-by-step explanation:

9 - x < - 11

In this scenario, we've to collect like terms in order to.wolve for x. This will be:

9 - x < - 11

- x < - 11 - 9

- x < - 20

Divide both side by -1

-x/-1 < -20/-1

When we divide by a coefficient with minus sign, the sign changes too from less than to greater than

-x/-1 < -20/-1

x > 20

The height of a cylinder is 10 and the area of a base is 36 pi square units. What
ollegr [7]

Answer:

1130.97336 units^3

Step-by-step explanation:

The volume of a cylinder can be found using:

v=\pi r^2h

We have the area of the base, but not the radius

a=\pi r^2

We know the area is 36\pi, so we can substitute that in for a

36\pi =\pi r^2

We want to find r, so we need to isolate it

Divide both sides by pi

36=r^2

Take the square root of both sides

6=r

Now we know the radius, and can substitute it into the volume formula, and we can substitute the height (10) in

v=\pi r^2h

v=\pi 6^210

Solve the exponent

v=\pi 36(10)

v=\pi 360

v=1130.97336

The volume is 1130.97336 units^3

Find the factored form of<br> -7y - y2 = 0
miskamm [114]

Answer:

-y(7+y) =0

Step-by-step explanation:

-7y - y^2 = 0

Factor out a -y

-y(7+y) =0

Using the zero product property

-y =0  and 7+y =0

y=0     7-7+y = 0-7

y=0    y = -7

In November 2010 the average cost of 5 gallons of regular unleaded gasoline in the United States was $14.46. What was the averag
Svetach [21]

Answer:

$46.72

Step-by-step explanation:

The first step is to find the price of 1 gallon

5 gallons= 14.46

1 gallon= x

5x= 14.46

x= 14.46/5

1 gallon= $2.92

Therefore the cost of 16 gallons of gasoline can be calculated as follows

1 gallon= 2.92

16= x

x= 2.92 × 16

= $46.72
