Set up;

(15^2)(CB) = (7.5^2)/(ST)

(15^2)/(5) = (7.5^2)/(ST)

Cross-multiply to find ST.

Answer:

Step-by-step explanation:

1. y = 3/2 x - 1

2. y = -2 x + 4

3. y = -3

4. x = 3

5. y = -5/9 x - 1

6. y = -2 x + 7

7. y = 16/5 x - 4

8. y = 8

9. y = -7 x + 5

10. y = -9 x - 2

Answer:

Step-by-step explanation:

Number 1s slope is 1/2, number 2 is -4/3. Number 3 is 0. Number 4 slope is also 0 i think. Number 5-10 im not sure

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

Answer:

x = 102

Step-by-step explanation:

The sum of all 3 angles of a triangle should equal 180 degrees, so 30+48=78 and 180-78=102.

Answer: Yes!

Step-by-step explanation:

Not only can a triangle have three acute angles (which is very common), you can also get triangles with angles so acute that their total sum is less than 180 degrees! This happens in a 'negative curved space'.

Answer:

Yes It can!

Step-by-step explanation:

If  it has 3 acute angles it means it is an acute triangle!

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.

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.

Answer:

y=2-(2/3)x

Step-by-step explanation:

4x+6y=12

subtract 4x from both sides

4x-4x+6y=12-4x

0+6y=12-4x

divide the equation by 6

6y/6=(12-4x)/6

y=12/6-4x/6

y=2-(2/3)x

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.

I answer is in your question

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.
