Jackson has a cube. Each edge of the cube is 5 centimeters long, as shown below.
Part A
Jackson paints every face of the cube. What is the total surface area, in square centimeters, of the cube
Jackson paints? Be sure to show your work and explain your reasoning.
Part B
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Part C
Jackson has a second cube identical to the first. He cuts off the triangular prism as shown below and throws
it away.
What is the volume, in cubic centimeters, of the remaining solid? Show or explain all your work.
Answer:
Part A- Surface area = 150cm squared
Step-by-step explanation:
First you find the area of one side of the cube-
side length (5) x side length (5) = area (25)
25 is the area of one side of the cube.
Then you multiple the area of one side (25) by the amount of sides that there are (6)-
25 x 6 = 150

I think it c
im sorry if im wrong
Answer:
B. 150 ft
Step-by-step explanation:
Perimeter of a rectangle = 2(Length) + 2(Width)
Here, we are given the perimeter and width and we want to find the length
We can do so by plugging in what we are given into the perimeter formula and solving for length.
Perimeter = 2(Length) + 2(Width)
Perimeter = 450 and Width = 75
450 = 2(Length) + 2(75)
We now solve for length
==> simplify multiplication 2(75) = 150
450 = 2(Length) + 150
==> subtract 150 from both sides
300 = 2(Length)
==> divide both sides by 2
150 = Length
And we are done!
The answer is B 150ft
Hello everyone can you answer this for me? What is A in the equation attached? Please and thank you.
Answer:
a = 6
Step-by-step explanation:
Hello!
Solve:
4(3a - 4) = 563a - 4 = 14 (factoring out 4)3a = 18 (adding 4 to both sides)a = 6 (dividing by 3)Another way:
4(3a - 4) = 5612a - 16 = 56 (distributive property)12a = 72 (moving like terms)a = 6 (dividing by 12)Distributive Property of Multiplication:
The process of distributing the outside factor to the terms in the parenthesis.
Example:
[tex]4(3a - 4)\\\\4(3a) - 4(4)\\\\12a - 16[/tex]

The horizontal flat box has dimensions of
h = 2
w = 7
l = 21
The vertical box has dimensions of
h = 10
w = 7
L = 12
Formula
V = L * w * h
Solution
Horizontal Flat Box = L*w * h
Horizontal Flat Box = 21 * 7 * 2
Horizontal Flat Box = 294
Vertical Box
Vertical Box = L * w * h
Vertical Box = 12*7 * 10
Vertical Box = 840

15. Classify Each Angle Pair then find the value of X
Answer:
These are alternate exterior angles
x=14
Step-by-step explanation:
Alternate exterior angles are formed by two parallel and one transversal line.
I suggest you do some research on transversal angles. I think that would be really helpful in the near future :)
Alternate exterior angles are also equal
Knowing this, we now understand:
5x-9=3x+19
2x-9=19
2x=28
x=14

If four students are playing a game and each student is equally likely to win the game, what is the probability that student 3 will win?
A.0
B.1/2
C.1/3
D.1/4
Answer:
D.
Step-by-step explanation:
Because since there are 4 people with an equal chance to win then you just put the number of people that you're trying to figure out over the total number.
Answer:
d
Step-by-step explanation:
we know there is 4 students so that means there's a 1/4 chance of him winning

what divided by 4 is 8?
Answer:
32
Step-by-step explanation:
If the question is x (standing for an unknown number) divided by 4 equals 8, then 8 times 4 should equal that unknown number.
x / 4 = 8
x / 4 (*4) = 8 (*4)
x = 32
We now can replace x with our number and see if this answer is valid.
x / 4 = 8
32 / 4 = 8
And yes, it is true. Therefore, 32 divided by 4 is 8.
I hope this helps! Have a lovely day!! :)
What value of y makes the equation 6(x-4)+2 = 36/4 true?
Answer:
31/6
Step-by-step explanation:
36/4=9
6x-22= 9
6x= 9+22
substitute 6x=31= 31/6
Answer:
x = 31/6
Step-by-step explanation:
first lets isolate the equation which equals, 6x-24+2 = 9
I got 9 from 36/4, divide top and bottom by 4 = 9
Next add the numbers, 6x -24+24= 9 turns into 6x-22= 9
Now move the -22 to the side the 9 is, 6x= 9+22
and now we can solve and substitute, 6x=31, which gives us 31/6

What is the approximate circumference of a circle with a diameter of 14 inches, rounded to the nearest inch? (Use 3.14 as an approximation of pi.)
Answer:
44 in.
Step-by-step explanation:
pi = 3.14 (in our case)
circumference = diameter x pi
circ. = 14 x 3.14, which equals to 43.96
round that and you get 44 in.

Find the missing angle measure.
Will give brainliest if possible!!
Answer: 35°
Step-by-step explanation:
Step #1: Write the 'triangle sum theorem' for the triangle which is:m∠A + m∠B + m∠C = 180°
Step #2: Substitute the given angle measures40° + 105° + m∠C = 180°
Step #3: Simplify.m∠C + 145° = 180°
Subtract 145° from both sides.
m∠C = 35°
So, the measure of the missing angle (x) is 35°.
