Answer:

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.

Hope this helps!!

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.

Hailey used 2 2/3 liters of cola to completely fill 2 bottles. If the bottles are all the same size, how many liters of cola does each bottle hold? Enter your answer below

Answers

Answer:

they each hold 1 1/3 litters of cola

Step-by-step explanation:

Because if there is 2 2/3 liters of cola

then you either divide it by 2

or you can look at it and see what would add evenly to make that number

in this case it would be 1 1/3

1 1/3 +1 1/3= 2 2/3

Alright so assuming the this is a right angle, to find the area of a triangle you have to multiply LxW and divide by 2. 3x4=12/2=6. There are 2 triangles, so 6x2=12

And then to find the area of the rectangle on the bottom, 10x4=40

Next you find the area of the rectangle on the side: 3x10=30

And finally the one that’s slanted on the top: 5x10=50

Add them up and 12+40+30+50= 132

Shane has a piece of rope that is 7 4/5 units long. If he cuts it into pieces that are each 3/5 of a unit long, how many pieces does he have?

Answers

Answer:

13 pieces

Step-by-step explanation:

7 4/5 divided by 3/5 is equal to 13

Number of pieces = (7 4/5) / (3/5) = (39/5) / (3/5) = (39/5) x (5/3) = 13 pieces

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

To find the Radius R we need Diameter which 290 fee so:

R = Diameter / 2

R = 290/2
