Answer:
3x^2-9x+3
Step-by-step explanation:
. You are mailing a gift box that is 18 inches by 8 inches by 12 inches. You
want to put it in a larger box and surround it with foam packing. The larger
box is 20 inches by 12 inches by 15 inches. How many cubic inches are
there for the foam packing?
Cubic inches of first box = 18 x 8 x 12 = 1,728 cubic inches
Cubic inches of larger box = 20 x 12 x 15 = 3,600 cubic inches.
Cubic inches for packing foam = 3600 - 1728 = 1,872 cubic inches
Answer: 1,872 cubic inches
Please help- A car travels 600ft in 20 seconds. A motorcycle travels 300ft in 12 seconds. Which is faster, the car or the motorcycle? Explain.
Answer:
The Car.
Step-by-step explanation:
We need to find the unit rate for each vehicle to figure out who is traveling faster or slower.
Car: 600/20 = 30 ft per second
Motorcycle: 300/12 = 25 ft per second
So, the Car is faster

Write an equation for the line that is parallel to the given line and that passes through the given point.
y = 2/3x + 5 (-3, 8)
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
[tex]y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{2}{3}}x+5\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
so we're really looking for the equation of a line whose slope is 2/3 and passes through (-3 , 8)
[tex](\stackrel{x_1}{-3}~,~\stackrel{y_1}{8})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{\cfrac{2}{3}}(x-\stackrel{x_1}{(-3)}) \\\\\\ y-8=\cfrac{2}{3}(x+3)\implies y-8=\cfrac{2}{3}x+2\implies y=\cfrac{2}{3}x+10[/tex]

Step-by-step explanation:
Bill weighs 120 pounds and is gaining ten pounds each month. Phil weighs 150 pounds and is gaining 4 pounds each month. How many months, m, will it take for Bill to weigh the same as Phil? *
Answer:
5 months
Step-by-step explanation:
120 * 10m = 150 * 4m
subtract 4m to 10m
120 * 6m = 150
subtract 120 to 150
6m = 30
divide 6 to 30
30 / 6 = 5

Find the median and mode of the following data.
Answer:
median = 50
mode = 52
Step-by-step explanation:
Answer:
Median: 50
Mode: 52
Step-by-step explanation:
To find the median, you arrange all of the numbers in order and find the number in the middle.If the number of values is an even number, the median will be the average of the two middle numbers.
The mode is the number that occurs the most in a set of data.
What is the lateral surface area of the square pyramid represented by this net?
Answer:
340 ft²
Step-by-step explanation:
From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width equals its length).
First, find the area of the square.
Area of a square = width x length = 10 x 10 = 100 ft²
All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.
Area of a triangle = 1/2 x base x height = 1/2 x 10 x 12 = 60 ft²
So the total area of all 4 triangles = 4 x 60 = 240 ft²
Therefore the total surface area = 100 + 240 = 340 ft²
Answer:
340 ft²
Step-by-step explanation:
The surface area of a shape is basically the area of its faces.
[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]
1. First, Let's find the area of the triangles. To find the area of a triangle, we need to multiply the height and the base and then divide the product by 2.
[tex]\rightarrow \text{Area of triangle} = \dfrac{12 \times 10}{2}[/tex]
Now, let's find the area of the triangle by simplifying the RHS.
[tex]\rightarrow \text{Area of triangle} = 6 \times 10[/tex]
[tex]\rightarrow \text{Area of triangle} = 60 \ \text{ft}^{2}[/tex]
Since there are four triangles, we need to further multiply the area of the triangle by 4 to find the area of four triangles.
[tex]\rightarrow \text{Area of four triangles} = 4(60)[/tex]
[tex]\rightarrow \text{Area of four triangles} = 240 \ \text{ft}^{2}[/tex]
2. Now, let's find the area of the square. To find the area of the square, we need to square the side length.
[tex]\rightarrow \text{Side length} = 10 \ \text{ft}[/tex]
[tex]\rightarrow \text{Area of square} = 10^{2}[/tex]
[tex]\rightarrow \text{Area of square} = 100 \ \text{ft}^{2}[/tex]
3. Lastly, let's find the surface area. To find the surface area of the figure, we need to sum up the area of the triangles and the area of the square.
[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]
[tex]\rightarrow \text{Surface area of pyramid: 240 + 100}[/tex]
[tex]\rightarrow \text{Surface area of pyramid: 340 \text{ft}}^{2} }[/tex]

select all of the equations that represent a nonlinear function
A. y= 3x(square)+9x+6
B. y=3x-10
c. y=2x+9x
d. y=x(3x+10)
e.y=x/3+10
Answer:
a. y = 3x² + 9x +6
d. y = x(3x + 10)
Step-by-step explanation:
Most equations that have a squared variable are going to be nonlinear.
If you distribute the x in the d equation you get this: y = 3x² + 10x
Choices b, c, and e are going to be linear because there is only one variable, and those variables do not have exponents.

Answer:
c. 13.9
Step-by-step explanation:
we can work out the third angle
all angles add up to 180
90 + 30 = 120, 180 - 120 = 60
using law of sines
[tex] \frac{x}{ \sin(a) } = \frac{b}{ \sin(b) } [/tex]
where sin(a) = 60, b = 30 and sin(b) = 30
[tex] \frac{x}{sin(60)} = \frac{8}{ \sin(30) } [/tex]
[tex]x = \frac{8}{sin(30)} \times \sin(60) [/tex]
x = 13.9

if line r bisects DG at point E, and if DE= 2z +2 and DG = 5z-7, then find DG
Answer:
DG = 48
Step-by-step explanation:
if line r bisects DG at point E, then point E is midpoint of DG
so DG = 2DE
5z - 7 = 2(2z + 2)
5z - 7 = 4z + 4
5z - 4z = 4 + 7
z = 11
DG = 5z - 7 = 5(11) - 7 = 55 - 7 = 48
