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.

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

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
The estimate obtained from a sample of which of the following sizes would
most likely be closest to the actual parameter value of a population?
A. 60
B. 180
C. 600
D. 300
Answer: I am doing this quiz right now I think the answer is C, 600.
Step-by-step explanation:
I think the higher you increase the sample size, the closer you get to the actual parameter.
The sizes that should be closest to the actual parameter value of a population is option c. 600.
What is estimation point?It represent the amount of the parameter that can be in the form of the mean or the standard deviation. Also, it helps for determining the confidence interval.
Also, we know that if the sample size is high so there should be more precise for the estimate.
So as per the given options, the option c is correct.

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

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 average of 3,3,16,19, and y is 10. what is y+6?
Answer:
y=9
9+6=15
y+6=15
Step-by-step explanation:
3+3+16+19+y=41+y
41+y/5=10
multiply both sides by 5
205+y/5=50
41+y=50
Rearrange the equation so y is isolated.
y= 50-41
y=9
Check:
3+3+16+19+9=50
50/5=10
y=9

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:
