In the following figure, three layers of cubes are stacked on top of each other. How many cubes of any size are in the figure?
Answer:
14
Step-by-step explanation:
It's 3x3, 2x2, and 1x1
9+4+1=14
Answer:
14 cubes
Step-by-step explanation:
The figure, there are 3 layers, so we can split up the layers.
In the 1st layer is just 1 cube.
In the 2nd layer:
2 x 2 = 4 cubes.
In the 3rd and final layer:
3 x 3 = 9 cubes.
We then add them:
1 + 4 + 9, giving us a total of 14 cubes.

1. How can you prove that a line parallel to one side of a triangle divides the other 2 sides proportionally?
2. In an isosceles triangle, how do you prove the base angles are congruent?
Answer:
1. You can prove that a line parallel to one side of a triangle divides the other 2 sides proportionally by using the Triangle Proportionality Theorem.
2. You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.

The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism. Find the volume of each figure. Rectangular prism: L= 6 ft. W= x H=3 ft. Triangular Prism: L= 7 ft W= x H=4 ft. Volume of rectangular prism: _ ft3 Volume of triangular prism: _ ft3 PLEASE ANSWER ASAP! I'M OFFERING A LOT OF POINTS!
Answer:
Step-by-step explanation:
Let the volume of a rectangular prism be VR and that of right triangular prism be VT. If The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism, then VR = 32 + VT
Since VR = length * width and height
VR = 6*x*3
VR = 18x ft³
Also VT = Length *width * Height/2
VT = (7 * x * 4)/2
VT = 28x/2
VT = 14xft³
Since VR = 32 + VT
18x = 32+(14x)
collect like terms
18x-14x = 32
4x = 32
divide both sides by 4
4x/4 = 32/4
x = 8
Volume of the rectangular prism = 18x
Volume of the rectangular prism = 18*8
Volume of the rectangular prism = 144ft³
Volume of the right triangular prism = 14x
Volume of the rectangular prism = 14*8
Volume of the rectangular prism = 112ft³
Answer:
rectangular is 114ft and triangular is 112ft
Step-by-step explanation:
Let the volume of a rectangular prism be VR and that of right triangular prism be VT. If The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism, then VR = 32 + VT
Since VR = length * width and height
VR = 6*x*3
VR = 18x ft³
Also VT = Length *width * Height/2
VT = (7 * x * 4)/2
VT = 28x/2
VT = 14xft³
Since VR = 32 + VT
18x = 32+(14x)
collect like terms
18x-14x = 32
4x = 32
divide both sides by 4
4x/4 = 32/4
x = 8
Volume of the rectangular prism = 18x
Volume of the rectangular prism = 18*8
Volume of the rectangular prism = 144ft³
Volume of the right triangular prism = 14x
Volume of the rectangular prism = 14*8
Volume of the rectangular prism = 112ft³

Olympic sprinter Usain Bolt's top speed is roughly 28 miles per hour. Convert this record-breaking speed to feet per sec. (1 mile = 5,280 feet)
Hey there! I'm happy to help!
28(5280)=147840 feet per hour.
There are 60 minutes in an hour. To find out how many feet Bolt runs in a second we divide by 60.
147840/60=2464
And we divide by sixty again to get to seconds.
2464/60=41 1/15 feet per second.
Have a wonderful day! :D
Multiply to feet.
28 * 5280 = 147840
Divide by an hour in minutes.
147840 / 60 = 2464
Divide by a minute in seconds.
2464 / 60 = 41 1/5 ft/s
Best of Luck!

The figures demonstrate a reflection are option (B) and option (D) are the correct answer.
What is a reflection of transformation?A reflection is a type of transformation. It maps one shape onto another. The function retains its basic shape; however, by including a negative sign in the appropriate place in the equation, the graph of the function will flip over one or the other of the axes.
For the given situation,
The options shows the different figures. we need to select the figure that correctly demonstrates the reflection.
Option A:
Here, the figure is not flipped on the axes.
The figure in option A does not show the transformation of reflection.
Option B:
Here, the figure is flipped on the axes.
The figure in option B shows the transformation of reflection.
Option C:
Here, the figure is not flipped on the axes.
The figure in option C does not show the transformation of reflection.

Answer:
40x30= 1200, 20x15=300, 300/1200= 1/4.
Step-by-step explanation:
You can also visualize it. Imagine a field 40’ long and the boy cut the top 20’ of it but left 20’ of the bottom, he would have cut half of it at this point. Now it’s 30’ wide and he cut the left 15’ of what’s remaining but left the right 15’ uncut. So now there’s a 20’x15’ bottom right corner left uncut. There are 4 sections that are 20’x15’ and he left one out of four uncut, otherwise written as 1/4.

The drama club is printing T-shirts for its members. The printing company charges a certain amount for each shirt plus set up fee of $40 they are 21 students in the drama club. If there are 21 students in the club and the T-shirt order cost a total of 187 how much does each T-shirt cost show your reasoning
Answer: $7
Step-by-step explanation:
Let x = Cost of each T-shirt.
As per given,
Total charge =( Number of t shirts x Cost per t shirt )+ set up fee
For 21 T-shirts , total charge would be : 21x+40
According to the question
⇒21x+40=187
⇒21x = 187-40
⇒21x = 147
⇒x= 7
Hence, each T-shirt costs $7 .

You purchased a computer for your business for $800. Using straight-line depreciation, the amount of depreciation allowed for each year after the purchase is given by the function f (x) = 800 − 114.29x. What type of function can you use to model the data?
Answer:
linear function
Step-by-step explanation:
The given function is linear function.
What is linear function?A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3[tex]x[/tex] - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with g([tex]x[/tex]), this function can be written as g([tex]x[/tex] )= 3[tex]x[/tex] - 2.
A linear function is of the form g([tex]x[/tex]) = m[tex]x[/tex] + b where 'm' and 'b' are real numbers. Here,
'm' is the slope of the line'b' is the y-intercept of the line'[tex]x[/tex]' is the independent variable'y' (or g([tex]x[/tex])) is the dependent variableGiven:

Norma Ann planned a rectangular courtyard, as shown in the scale drawing below. She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. Which expression finds the change in the scale factor? PLSS HELP!
Answer: 45 / 40 ft
Step-by-step explanation:
Given that She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. Which expression finds the change in the scale factor?
Actual width of shorter side = 45 ft
New width of shorter side = 40 ft
Scale factor is the ratio of the actual length to the new or intended length
Scale factor = Actual width / New width
Hence, scale factor :
45 ft / 40 ft
