Step-by-step explanation:

r/3 = 18

r/3 * 3 = 18 * 3

r = 54

Answer:

54

Step-by-step explanation:

multiplication is the opposite of division so you can do 18*3=54 and you can check that by dividing 54 and 3 and the answer is 18

Answer:

(3x + 1)(2x + 1)

Step-by-step explanation:

Remark

This thing really does factor.

Both the first and last coefficients are prime, so if it factors easily 1 and 3 and 1 and 2 must be there somewhere.

(3x + 1)(x + 2)    would be the logical guess. That turns out to be correct.

Complete question

Emma receives a large box in the mail. The box is 10cm longer than it wide, and the height is 6 cm more than the width. Find the polynomial function for volume of the box

Let the length be x

Let the width be y

let the height be z

If the box is 10cm longer than it wide, then x = y + 10

Also if the height is 6 cm more than the width,

z = y + 6

Volume of the box = xyz

Substitute

Volume of the box = (y+10)(y)(y+6)

Volume of the box = (y+10)(y²+6y)

Volume of the box = y³+6y²+10y²+60y

Volume of the box =  y³+16y²+60y

Hence the required polynomial function is y³+16y²+60y

Answer:

3 or 3/1

Step-by-step explanation

the equation for finding the slope when given two coordinate pairs is (y₂ - y₁)/(x₂ - x₁), aka change in y over change in x.

pick one of your coordinate pairs to be y₂ and x₂. it doesn't matter which coordinate pair you choose. the remaining coordinate pair will be your y₁ and x₁.

for this example, i'll use the coordinate pair (7, 2) as my y₂ and x₂ and (1, 4) as my y₁ and x₁.

first, substitute the x-value and y-value from the first coordinate pair.

(y₂ - y₁)/(x₂ - x₁) ⇒ (7 - y₁)/(2 - x₂)

then substitute the y-value and x-value from the remaining coordinate pair.

(7 - y₁)/(2 - x₂) ⇒ (7 - 4)/(2 - 1)

subtract 7 - 4.

(7 - 4)/(2 - 1) ⇒ (3)/(2 - 1)

subtract 2 - 1.

(3)/(2 - 1) ⇒ (3)/(1) or 3/1

simplify.

3/1 ⇒ 3

Answer: 60 feet²

Step-by-step explanation:

The width of the rectangular room is 60% of the length which is 10 feet.

The width is therefore:

= 60% * 10

= 6 feet

The area of a rectangle is calculated by the formula:

= Length * Width

Area there is:

= 10 * 6

= 60 feet²

Answer:

Only one circle can be drawn through three non nonlinear points, No circle can be drawn through three nonlinear points

Step-by-step explanation:

A circle has a curve. As long as the three non nonlinear points both have the same amount of distance from the center of the circle it can be a circle drawn. No circle can be drawn through three points on the line.

x= -3, -7

Answer:

x = -7, -3

Step-by-step explanation:

Try to factor the left side of the equation.  

(x +7)(x + 3) = 0    Remember that if AB = 0, then A = 0 or B = 0 or both  A and B = 0

Therefore,  x + 7 = 0  or x + 3 = 0

                        x = -7  or x = -3

Answer:

c=175n

Step-by-step explanation:

The value of the function at x = -3 is -1

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.

Given that a graph of y= f(x), we need to find f(-3)

The graph tells the value of y when x = -3 is -1

Hence, The value of the function at x = -3 is -1

Answer:

[tex]34in^2[/tex]

Step-by-step explanation:

First, you should find the area of the trapezoid which the formula for that is:

[tex](b1 + b2)h/2[/tex]

So, you will ad up 7in and 3in, and you should get 10in.

Now multiply 10 in by the height which is 5in, so it will be 50in^2. Then you have to divide that by 2 turning it into 25in^2.

For the top part, it is basically a triangle so you just multiply 3 by 6, giving you 18/2 = 9in^2

Add the two together and you should get 34in^2

Answer:

y=-1/4x+2

Step-by-step explanation:

The equation would be y=-1/4x+2 because the rise is -1 and the run is 4 (you could also say the run is -4 and the rise is 1. It doesn't really matter). The line also crosses the y axis at 2, which means that 2 is the y-intercept. :)

Answer:

y = (-1/4)x +2

Step-by-step explanation:

Having the actual graph is an easy way to calculate the equation of the line. Since the format is y = mx +b we just need to plug in numbers.

b = y-intercept

m = slope

We can automatically see that the y-intercept is 2, so b = 2. To find the slope we just calculate rise over run. The line is decreasing 1 unit for every 4 units it is "running". Therefore, -1/4 is your slope.

b = 2

m = -1/4

Now, all we need to do is plug in numbers.

y = (-1/4)x +2

Answer:

3 gallons

Step-by-step explanation:

Length of the rectangular wall = 23.6 feet

Width of the rectangular wall = 19.2 feet

Surface area of the wall = 23.6 × 19.2

                                        = 453.12 square feet

∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon

∴ 1 square feet of the wall will be covered by the amount of paint = [tex]\frac{1}{200}[/tex] gallons

∴ 453.12 square feet will require the amount of paint = [tex]\frac{453.12}{200}[/tex]

                                                                                         = 2.2656 gallons

Therefore, minimum 3 gallons will be required to paint the wall.

Exact answer = 26π/45 feet.

or we can write it as 1.815 feet to the nearest thousandth.

Step-by-step explanation:

The circumference of the circle = 2*4*π = 8π feet.

So the length of S = (26/360) * 8π
