Answer:

[tex]Vc = 2,261.9\ in^3[/tex]

Step-by-step explanation:

Volume of a Cylinder

The volume of a cylinder of radius r in and a height h can be calculated by:

[tex]Vc=\pi\cdot r^2\cdot h[/tex]

The height of the cylinder is h = 20 in and the base radius is r = 6 in, thus:

[tex]Vc=\pi\cdot 6^2\cdot 20[/tex]

[tex]Vc = 2,261.9\ in^3[/tex]

Answer:

[tex]y=-\frac{1}{3}x+1[/tex]

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Where 'm' = slope of the line

b = y-intercept

From the picture attached,

b = 1

Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is represented by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the line passing through the points (0, 1) and (3, 0) will be,

m = [tex]\frac{0-1}{3-0}[/tex] = [tex]-\frac{1}{3}[/tex]

Equation of the line will be,

[tex]y=-\frac{1}{3}x+1[/tex]

Answer:

Yes

Step-by-step explanation:

12/21 simplified is 4/7. if you divide the numerator (12) by 3 and the denominator (21) by 3, you get 4 and 7, or 4/7 if you put it together.

4/7 and 12/21 are equivalent fractions

A fraction represents a part of a whole.

We need to check whether the fractions  4/7 and 12/21  are equivalent or not.

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value.

12/21 we have to simplify.

12 and 21 are the multiples of 3, so  divide numerator and denominator by 3

which gives 4/7

12/21=4/7

Hence, 4/7 and 12/21 are equivalent fractions

Answer:

7x+12x=82$

Step-by-step explanation:

Dalyn is selling girl scout cookies. She sold 7 boxes of thin mints (x) and 12 boxes

of tagalongs (y). If she made $82 selling cookies, write an equation that

represents the scenario. *

Step-by-step explanation:

p/q=2/3

q/r=6/5

First q is to be made same . So take LCM of 3 and 6 which is 6 only.

Now,

p/q=2×2/3×2=4/6

q/r=6/5 only

Cancel both the 6.

Therefore the answer is p/r=4/5.

Answer:

  A. f(x)=56,000(0.93)x+8400

Step-by-step explanation:

The growth rate is -7%, so the growth factor will be 1 -7% = 0.93. This is the base of the exponential term.

The 8400 special passes will add 8400 visitors to the park in addition to those who pay the regular fee. Thus the number of visitors is ...

  f(x) = 56,000(0.93^x) +8400 . . . . matches choice A

Answer:

A) [tex]5x-1=-6[/tex]

B) [tex]x=-1[/tex]

Step-by-step explanation:

On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression [tex]5x-1[/tex].

On the right, we have six -1s. So, we can represent the right with the expression [tex]-6[/tex].

A)

Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:

[tex]5x-1=-6[/tex]

B)

Now, we can solve the equation for x. Add 1 to both sides:

[tex](5x-1)+1=(-6)+1[/tex]

The left will cancel. Add on the right:

[tex]5x=-5[/tex]

Finally, divide both sides by 5:

[tex](5x)/5=(-5)/5[/tex]

The left side will cancel. So, the value of x is:

[tex]x=-1[/tex]

Answer:

A)  5x-1=-6

B) x=-1

Step-by-step explanation:

Both are 123

When dealing with angles you have to remember that all angles add up to 180, “the line angle” as I like to call it, it’s because 180 is completely flat.

2: Here you can use your eyes to see the angle is wider than 90, ”a perfect right”. So you can easily assume that the angle is gonna be 123.

1: the angle here shares the same place as your original angle. So you can easily assume that they have the same degree

Answer:

$7.99 for 10 cans

Step-by-step explanation:

First you want to see what the price is for one can. Do this by dividing 6 from 4.99 (4.99/6). This gives you 83 cents per can. Do the same for the other, and you get 79 cents per can. 79 cents is a better value than 83 cents.

Answer:

14) No. 15) No. 16) Yes. 17) Yes.

Explanation:

When something is not a function, you can either use the vertical line test which involves drawing a line going up and down to see if the graph hits the line more than once. If this is the case, it is not a function. Or the input or x value of a function cannot have more than one

output or y value.

The line x = |y| on the graph of #14 is not a function because there is more than one y value for a single x value. This also hits a vertical line more than once.

The table on #15 is not a function because their is more than one y value per x value. It also hits a vertical line more than once.

The equation y = 1/4x is a function because there is only one output for each input. This also does not hit a vertical line more than once

The equation x = y - 1 is a function because it is simply a rearanged version of y = x + 1 which has only one output for each input. It also does not hit a vertical line more than once.

Answer:

Alright well first off you start by converting everything to fractions, but decimals work better for me. So it would be 40.5 and 1.25, 40.5 being miles and the other gas. Divide 40.5 by 1.25, giving you 32.4

Answer: May you give the statements?

Step-by-step explanation:

Answer:

Step-by-step explanation:

Where is the statement?

Answer:

Answer is -10

Step-by-step explanation:

Explanation:

First, define the variable. Let n represent the unknown number.

Next, write an equation to represent the situation. Because a quotient is the result of division, divide the unknown number by -5:

.

Then, use opposite operations and the properties of equality to solve for n. Notice that the variable, n, is divided by -5. So, to isolate n, do the opposite and multiply both sides of the equation by -5:

Finally, to check the solution, substitute -10 for n in the original equation:

The resulting statement is true, so the solution is correct.

Answer: (F-G)(x)=5x2+2i +1

Step-by-step explanation

The resulting function for (f−g)(x) is 2x²+x-3

Let the required functions be:

f(x)=2x²+3x

g(x)=2x+3

We are required to find (f−g)(x).

(f−g)(x). = f(x) - g(x)

(f−g)(x) = 2x²+3x - (2x+3)

(f−g)(x) = 2x²+3x - 2x - 3

(f−g)(x) = 2x²+x-3

Hence the resulting function for (f−g)(x) is 2x²+x-3
