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

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.

Answers

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

A school fundraiser has a minimum target of $600. Faculty donated $200 and there are 10 student clubs that are participating with different activities. Write an inequality showing the amount money each club should raise to meet the minimum target. Use f for the amount of money that each club raises.

Answers

So you add 600$+200$ then divide it by ten

Answe is:80$

The target goal is 600. 600-200=400. 400 divided by the 10 clubs is 40. Each club needs to raise $40. F=$40

what divided by 4 is 8?

Answers

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.

Find the missing angle measure.


Will give brainliest if possible!!

Answers

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 measures

40° + 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°.

What value of y makes the equation 6(x-4)+2 = 36/4 true?

Answers

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

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

During gym class, Lenny, Lonnie, and Lainey measure the length of their long jumps. Lenny’s jump is ⅔ times the length of Lainey’s, and Lonnie’s jump is 1⅓ times the length of Lainey’s. Whose jump is the longest? Why? pls help!!

Answers

Answer: Lonnie’s Jump

Step-by-step explanation:

         (They just had to give three names that all started with L.)

         Since Lenny's jump is ⅔ times the length of Lainey’s, we can tell that Lenny's jump won't be the longest because it is already smaller than Lainey's.

         Since Lenny is now out of the picture, let us look at Lonnie and Lainey. Lonnie’s jump is 1 ⅓ times the length of Lainey’s. Since Lonnie's jump is longer than Laniey's, Lonnie's jump is the longest jump.
