Answer:

The answer is A and C

Step-by-step explanation:

The answer is A because 12.3 multiplied by 10 is 123, and 0.4 multiplied by 10 is 4.

12.3 * 10 = 123

0.4 * 10 = 4

So, this shows that this equation is the same as 12.3 divided by 0.4

The answer is C because 12.3 multiplied by 100 is equal to 1230, this is the same for 0.4

12.3 * 100 = 1230

0.4 * 100 = 40

So, the answer is both A and C.

Hope this helps! :)

Answer:

12.3 divided by 0.4 is 30.75

Step-by-step explanation:

You then go to letter A and 123/4 is also 30.75

but you go through the rest of the choices just in case.

B is 3.075 so that is incorrect

C is 307.5 so that is also incorrect

D is 3075 and that is incorrect and not 30.75.

Therefore your answer is A.

30.75 = 30.75.

Answer:

$626.75

Step-by-step explanation:

First, we must find how much tax will be added to the TV's price:

Step 1: Convert the percentage to a decimal:

To convert a percentage to a decimal, divide it by 100

8.25/100 = 0.0825

Step 2: Multiply the TV's price by that decimal:

578.98 * 0.0825 = 47.76585

So $47.76585 will be added to the price

Now, we can calculate the total price:

Step 3: Add the tax we jsut calculated to the TV's price to find total price:

578.98 + 47.76585

= 626.74585

Step 4: Round to the nearest cent (2 decimal places)

626.75

So the total price is $626.75

Since each value of the input is mapped to only one value of the output, we have that graph w represents a function.

When it has no vertically aligned points, that is, each value of x is mapped to only one value of y.

Hence, in this problem, graph w represents a function.

Let's assume that the peak value Given is 108.7m

However, If that is not the actual value, then you can just follow the steps with the actual value to obtain your answer.

Answer:

101.2 meters

Step-by-step explanation:

Taking the peak Given as 108.7 m

The distance traveled by car = 7. 5 meters

The distance left to reach the top of the mountain :

108.7 meters - 7.5 meters

= 101.2 meters

The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13

The two lines can be anything as long as they give this solution

For example, if you wrote x + y = 16 (you know their values already)

Then write another y - x = 10

From here you have your equations, turn them into the f(x) form.

x + y = 16 can be turned into y = 16 - x which is f(x)=16-x

y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x

Answer:

[tex]300\pi[/tex] cubic feet

Step-by-step explanation:

Let r be the radius of cone and h be the height of cone.

Radius of cylinder=r

Height of cylinder=h

Volume of cone=[tex]100\pi ft^3[/tex]

We have to find the volume of cylinder.

We know that

Volume of cone=[tex]\frac{1}{3}\pi r^2 h[/tex]

[tex]100\pi=\frac{1}{3}\pi r^2 h[/tex]

[tex]r^2 h=300[/tex]

Volume of cylinder=[tex]\pi r^2 h[/tex]

Using the formula

Volume of cylinder=[tex]\pi (300)=300\pi ft^3[/tex]

Hence, the volume of cylinder=[tex]300\pi[/tex] cubic feet
