Mr. Crosgrove tipped $3.84.

120 pens are not red pens.

She had to pay $270 in taxes.

Step-by-step explanation:

So, to find the percentage of something you convert the percentage to a decimal and then multiply.

For #1

He spent $48, and tipped 8%

to turn 8% into a decimal you bring in down two place values, so it is 0.08. You multiply 48 * 0.08 and you get 3.84.

Mr. Crosgrove tipped $3.84.

For #2

He has 150 flair pens and 20% are red. Multiply 150 by 0.2. You will get 30. Now we know that there is 30 red pens, but the problem is asking how much is not red pens. subtract 150-30 and you get 120, so that is the answer.

120 pens are not red pens.

For #3

She has $2,000 and had to pay 13.5% You have to turn 13.5% into decimal so bring place value down by two so it is now 0.135. Multiply 2,000*0.135 and you get 270.

She had to pay $270 in taxes.

Angle of a straight line always sum up to 180 degrees
So what you should do is add the angles that are given to you and then subtract it from 180
Working:
100 + 20 + x = 180
120 + x = 180
x = 180 - 120
x = 60 degrees

Can some help me with this? It’s volume and I have to show work.

Answers

To find volume, you'll just need to multiply the Length, Width, and Height. It's very simple. Let's go over it step-by-step.

Now, the formula is L × W × H. Like I've said before, it is very simple.

In this problem, 18 is the Length, 6 is the Width, and 16 is the Height.

We now have the Length, Width, and Height.

18 ⇒ Length

6 ⇒ Width

16 ⇒ Height

Let's multiply now.

18 × 6 × 16 = 1,728 in (Do not forgot the unit)

Therefore, the volume is 1,728 in.

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y = 1/2x+2

Step-by-step explanation:

First find the slope using y1-y2 over x2-x1 picking two points, the two I am using are (0,2) and (2,3). Once I use the formula, the slope is 1/2. The Y intercept (b) is where the line intersects it. (0,2) You know it is the y intercept because the x coordinate is 0. So the final equation would be y=(slope)x+ (y-int) so FINAL ANSWER: y=1/2x+2

What is the volume, in cubic centimeters, of a cylinder with a height of 12 centimeters and a base radius of 6 centimeters, to the nearest tenths place?

Please help :(

Answers

Answer:

1357.2

Step-by-step explanation:

volume = r^2 * pi * h

= 6^2 * pi * 12

=432pi

The volume of cylinder is 1357.17 cubic centimeter.

Formula to find the volume of cylinder:

V = base area × height

[tex]V=\pi \times r^{2} \times h[/tex], where r is the radius of circular base and h is the height of the cylinder.

For given example:

a base radius (r) = 6 cm,

a height of a cylinder (h) = 12 cm

Using the formula of volume of a cylinder,

[tex]V=\pi \times 6^{2} \times 12[/tex]

[tex]V=1357.17[/tex] cubic cm

Hence, the volume of a cylinder is 1357.17 cubic centimeter.
