The answer is D. t<-3 because a number like -10 is less than -3. plug in a -10 for t and you would get -50<-15 which is true

The result of dividing (x3 + x2 – 22x – 40) by

IceJOKER [234]

Answer:

(x + 2) (x + 4)

Step-by-step explanation:

Before looking at my explanation make sure next time you are going to ask another question write the numbers that include exponents like this: x^2 instead of x2

Factor out x^2:

x + x

Factor out 6x:

Since it is in the bx form we’ll need two numbers be add so it can be equivalent to 6x

Answer: 4 and 2

Factor out 8:

4 x 2

Now start with the 8 and 6x

(? + 4) + (? + 2)

Then finish it off with x

(x + 4) (x + 2)

The measure of one a cite angle of a right triangle is 6 less than twice the measure of the other acute angle find the measure o

jeka57 [31]

Answer:

32°, 58°

Step-by-step explanation:

Let one acute angle measure x.

The other acute angle measures 2x - 6.

The sum of the measures of the acute angles of a right triangle is 90.

x + 2x - 6 = 90

3x - 6 = 90

3x = 96

x = 32

2x - 6 = 2(32) - 6 = 58

Answer: 32°, 58°

A cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.

Anton [14]

Answer:

Height of cylinder is $\frac{4}{5}\ ft$ .

Step-by-step explanation:

Diameter of cylinder, D = 6 feet

Relation between Radius, R and diameter, D is given by:

$R = \dfrac{D}{2}$

So, radius, R = $\frac{6}{2} \Rightarrow 3$ feet

Let height of cylinder be $h$ feet.

Formula for volume of cylinder is given by:

$V = \pi R^{2} H$

Where, R is the radius of base of cylinder

and H is the height of cylinder

We are given that,

$V = \dfrac{36 \pi}{5} ft^{3}$

Using formula for volume, $V = \pi R^{2} H$

$\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft$

Hence, Height of cylinder is $\frac{4}{5}\ ft$ .

Three people share half a pizza evenly. What fractional part of the original pizza does each one get?

beks73 [17]

Answer:

The fractional part of the original pizza is $\frac{1}{6}$

Step-by-step explanation:

Let

x-----> the original pizza (complete pizza)

we know that

Half a pizza represent ------> $\frac{x}{2}$

Divide half a pizza by three people

$(\frac{x}{2})/3=\frac{x}{6}$

therefore

The fractional part of the original pizza is $\frac{1}{6}$
