The circumference of a cylinder is 20 inches and the volume is 600 cubic inches. Calculate the height.

Answers

Answer:

h = 18.88 inches

Step-by-step explanation:

Given that,

The circumference of a cylinder is 20 inches

The volume of the cylinder, V = 600 cubic inches

We need to find the height of the cylinder. We know that the volume of a cylinder is given by :

[tex]V=\pi r^2h[/tex]

r is radius

We know that,

circumference = 2πr

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{20}{2\pi}\\\\r=3.18\ \text{inches}[/tex]

So,

[tex]h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{600}{\pi\times (3.18)^2}\\\\h=18.88\ \text{inches}[/tex]

So, the height of the cylinder is 18.88 inches.

The sum of Andy and Brett's ages is 44.
Andy's age is 8 more than twice Brett's age.
What are the variables in this situation?

Answers

Answer:

The variables are A and B. A for Andy, and B for Brett. B=18, and A=26

Step-by-step explanation:

A+B=44

A=B+8

B + 8 + B = 44

2B+8=44

2B = 36

B = 18

A = 26

Answer:

253cm²

Step-by-step explanation:

Area of the trapezoid = 1/2(b1+b2)*h

Given

h = 22cm

b1 = 10.5cm

b2 = 12.5cm

Substitute

Area of the trapezoid = 1/2(10.5+12.5)*22

Area of the trapezoid = 1/2(23)*22

Area of the trapezoid =11*23

Area of the trapezoid = 253cm²

Hence the area of the trapezoid is 253cm²

Which term makes the equation y=sup(x,3)+2x+1 nonlinear?

Answers

Answer:

sup(x,3)

Step-by-step explanation:

Linear equation:

A linear equation has the following format:

[tex]y = ax + b[/tex]

In a linear equation, when x changes by 1, y will always change by the amount a, which is called slope.

In this question:

y=sup(x,3)+2x+1

[tex]y = 2x + 1[/tex] would be a linear equation.

However, the expression sup(x,3), that is, the higher value between x and 3, means that the function is not linear.

Answers

Answer:

Step-by-step explanation:

Convert the 25% discount into a decimal, which is 0.25Multiply the original listed price ($500) by the discount as a decimal (0.25), which is $125Subtract the original list price ($500) by $125 (the discount as a number). This is $375, which is the answer.

No, Maria is incorrect.

Let me know if this helps!

We now have two formulas for (a+b)², which means we can set equation 1, from earlier, and equation 2 equal to one another.

[tex]7[/tex]

Step-by-step explanation:

This means that there are 20 terms in between 11 and 31

[tex]31-11=20[/tex]

Since we know that the [tex]11th[/tex] term is [tex]29[/tex] and the [tex]31st[/tex] term is [tex]169[/tex], you can subtract the two to find out the values in between

[tex]169-29=140[/tex]

Now all we have to do is divide the values in between by the number of terms to find the common difference.

[tex]\frac{140}{20} =7[/tex]

Therefore the common difference is [tex]7[/tex]

He lay on his armor-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked.Whats happened to me? he thought. It wasnt a dream.Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the pane, which made him feel quite sad. How about if I sleep a little bit longer and forget all this nonsense, he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldnt get into that position. However hard he threw himself onto his right, he always rolled back to where he was. He must have tried it a hundred times, shut his eyes so that he wouldnt have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before.There was a cautious knock at the door near his head.
