He would be payed $290, you just have to do a "cross multiplication" (as we call it in french), you just have to do 174×40÷24 and there you go :)

a foreman must order enough sod to cover a dirt area 36 feet wide by 28 feet long. each piece of sod is 3 feet long and 12 inche

Andrews [41]

If we divide the area we have to cover by the area of a piece, we will get the number of pieces needed:

$n=\dfrac{\text{dirt area}}{\text{piece area}}=\dfrac{36\times 28}{3\times 12} = \dfrac{36\times 28}{36}=28$

The rectangle shown has a perimeter of 7272 cm and the given area. its length is 66 more than four timesfour times its width. wr

Vadim26 [7]

<span>Width = 6 Length = 30 We know the perimeter of a rectangle is simply twice the sum of it's length and width. So we have the expression: 72 = 2*(L + W) And since we also know for this rectangle that it's length is 6 more than 4 times it's width, we have this equation as well: L = 6 + 4*W So let's determine what the dimensions are. Since we have a nice equation that expresses length in terms of width, let's substitute that equation into the equation we have for the perimeter and solve. So: 72 = 2*(L + W) 72 = 2*(6 + 4*W + W) 72 = 2*(6 + 5*W) 72 = 12 + 10*W 60 = 10*W 6 = W So we now know that the width is 6. And since we have an expression telling us the length when given the width, we can easily determine the length. So: L = 6 + 4*W L = 6 + 4*6 L = 6 + 24 L = 30 And now we know the length as well.</span>

What is the remainder of (3x^4+2x^3-x^2+2x-14)/ (x+2)

Allisa [31]

Hi,

I assume the forward slash meant it as a fraction VS it being a division symbol. To answer your question, the remainder is 10.

Hope this helps.

The graphs show the amount of sugar in two kinds of juice.

gizmo_the_mogwai [7]

Answer:

Pat a) The unit rate of graph at left is $25\ \frac{grams}{cup}$

Part b) The unit rate of graph at right is $40\ \frac{grams}{cup}$

see the attached figure

Step-by-step explanation:

we know that

The unit rate of a linear equation is the same that the slope of the linear equation

step 1

Find the slope of the graph at left

This graph represent a proportional relationship (because the line passes through the origin)

The slope is equal to the constant of proportionality k

$k=\frac{y}{x}$

we have the point (1,25)

substitute the values in the formula

$k=\frac{25}{1}=25\ \frac{grams}{cup}$

step 2

Find the slope of the graph at right

we have the points (2,80) and (3,120)

This graph represent a proportional relationship (because the line passes through the origin)

The slope is equal to the constant of proportionality k

$k=\frac{y}{x}$

Is necessary only one point to determine the constant of proportionality

take the point (2,80)

substitute the values

$k=\frac{80}{2}=40\ \frac{grams}{cup}$

<u>Verify</u>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the points (2,80) and (3,120)

substitute the values

$m=\frac{120-80}{3-2}$

$m=\frac{140}{1}=40\ \frac{grams}{cup}$
