Answer:

Volume of a Cylinder:

In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.

The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.

Answer:

240$

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

Sandra

t = 1 year

I= $75

P= $2,500

r= ?

substitute in the formula above

75=2,500 (r(1))

solve for r

r=75/2,500)

r= 0.03

Convert to percentage form

r= 0.03 * 100 = 3%

Ron

t=1 year

I = ?

P= 8,000

r= 0.03

substitute in the formula of interest

I = 8,000(0.03 *1)

I = $240

I thought of 24 and 14 and the larger number is 24

Step-by-step explanation:

24-16=8

The larger number will be "32".

Let the two numbers:

and,

By applying the subtraction between the above two numbers, we can find the difference between the numbers.

So,

→ [tex]32-24[/tex]

→ [tex]8[/tex] (difference)

We can see that the greater number between "32" and "24" is "32".

Thus the above answer is right.

Answer:

x=21.9317121994

Step-by-step explanation:

You just look at the half triangle and use the Pythagorean Theorem.  One side of the triangle is 9 (half of 18), the other is 20, so you find the hypotenuse.

9²+20²=x²

81+400=x²

481=x²

√481=x

x=21.9317121994

Step-by-step explanation:

You run a train station that sells children tickets for 2 dollars and adult tickets for 4 dollars

How many adult tickets and kid tickets did they sell?

(40 kids, 10 adults)

A pen cost $40 and the book cost $10

The word problem that can be represented by the equation is: John bought one pen and one book for $50. He went the next day and bought 2 pens and 4 books for $120.

x + y = 50 ....... i

2x + 4y = 120 .... ii

Let x = pen

Let y = book.

From equation i, x = 50 - y

Since 2x + 4y = 120

2(50 - y) + 4y = 120

100 - 2y + 4y = 120

Collect like terms

-2y + 4y = 120 - 100

2y = 20

y = 10

Therefore, a book cost $10

Since x + y = 50

x + 10 = 50

x = 50 - 10

x = 40

A pen cost $40
