What is the area of the rectangle written in simplest form

Valentin [98]

Answer:

option D

Step-by-step explanation:

5/6 x 4/6

Multiply the numerators only.

it will give you--> 20/6

You can simplify this down by dividing 20 by 6 giving you 3 remainder 2

Putting this in fraction form would give you 32/6 which can be simplified to

3 1/3 ft^2

Suppose you work for a sporting goods company, and you want to order shipping boxes for bike helmets. Each helmet is already pac

madreJ [45]

Answer: $n^2+6n-135=0$

Step-by-step explanation:

The length, width and height of the smaller box are n inches , n inches and 8 inches respectively,

And, According to the question,

The shipping boxes has 2 inches extra width than that of smaller box and 4 inches extra length than that of smaller box, Also, The height of the shipping box should be the same as the helmet box.

Thus, the Length of the shipping box = (n + 4) inches

Width = (n+2) inches and height = 8 inches

Thus, the volume of the shipping box,

$V = (n+4)\times (n+2)\times 8=(n^2+6n+8)8=8n^2+48n+64$

But, V = 1,144 cubic inches,

⇒ $8n^2+48n+64=1144$

⇒ $n^2+6n+8=143$

⇒ $n^2+6n-135=0$

Which is the required equation that models the volume of the shipping box.

Determine the x- and y-intercepts of the graph of y=−1/3x+1<br><br> Please, I need an answer ASAP!

VikaD [51]

Answer:

y = 1 x = 3

the +1 at the end of the equation is the y intercept while the number with the x is the slope, since the slope is -1/3 take it as if it was rise/run. In other words since the rise is -1 you are going down 1 unit and the run is 3 you are going 3 units to the right & that's the path its going to be taking. So that makes the line cross the x axis at (0,3)

Assuming a linear relationship between x and y, if the coefficient of correlation (r) equals -0.75, this means that:

Gelneren [198K]

Since we are given that the relationship between x and y is linear. Therefore this means that the given equation takes the form of:

y = m x + b

where,

b is the y intercept of the equation

m is the slope of the equation

However we should take note that the slope m is directly proportional to the coefficient of correlation. Since our coefficient of correlation is negative, this only means that the value of y is decreasing with increasing x, hence plot of y and x is descending with increasing x. Furthermore, this also tells that for every 1 unit increase of x, there is a 0.75 units decrease of y.
