HELP! Two right rectangular prisms are shown below. If each prism is packed with small cubes of side length 1/4 inch how many more cubes are in prism 2
A. 42 Cubes B. 48 Cubes
C. 510 Cubes D. 720 Cubes
Answers
Answer:
First find the volume of the two rectangular prisms using the formula:
V = l · w · h
Where 'l' represents the length, 'w' the width, and 'h' the height.
Now let's find the volume of Prism 1;
V = l · w · h
V = 7/4 · 3/2 · 5/4
V = (7/4 · 3/2) · 5/4
V = 21/8 · 5/4
V = 105/32 cubic inches.
Now let's find the volume of Prism 2;
V = l · w · h
V = 5/2 · 9/4 · 2
V = (5/2 · 9/4) · 2
V = 45/8 · 2/1(make 2 to 2/1 because it makes it a bit easier)
V = 90/8 cubic inches.
Now let's find how many cubes can fit into each of these prisms.
But first, we need to find out the volume of one cube.
Remember, all sides to a cube are equal.Using the formula, V = l · w · h;
1/4 · 1/4 · 1/4
= 1/64 cubic inches is the volume of one cube.
Now we find how many cubes can fit inside each of these prisms.
Prism 1:
105/32(volume for this prism) ÷ 1/64(volume of one cube)
= 210 cubes can fit inside prism one.
Prism 2:
90/8(volume for this prism) ÷ 1/64(volume of one cube)
= 720 cubes can fit inside prism two.
Finally, let's calculate their difference:-
720 - 210
= 510 cubes.
Hence, prism 2 can hold 510 more cubes than prism 1.

Part A: Explain why x = 6 makes 5x − 6 ≤ 24 true but not 5x − 6 < 24. (5 points)
Part B: What value from the set {5, 6, 7, 8, 9} makes the equation 6x + 4 = 34 true? Show your work.
Answers
Answer:
I dont know about A but the answer for B is below
Step-by-step explanation:
6x + 4 = 34 = (6x5) + 4 = 34
Answer:
Seem you are doing the same test I did! Module 7 part 2?
Anyway!
Part A: If we work through the equation 5x - 6 and substitute 6 for x then we have (5*6) - 6 = 30 - 6 = 24.
Therefore, 5x − 6 ≤ 24 is true since it means that it is equal to or less than 24.
And 5x − 6 < 24 is wrong since the equation equals 24 and is not less than 24.
Part B:
6x + 4 = 34
6x5 = 30
30+4=34
To verify: (6*5) + 4 = 34. The answer is five.
Hope this helps! Brainliest please!

a) 56 beads
b) 8 beads
Step-by-step explanation:
12 beads take 3 inches so yes 12/3 =4 per inch
but then the necklace is 14 in long so 4 *14=56 beads
if you take off one ince per side you would take of 4 beads per side so 4*2=8 beads

9 =[tex]\frac{3x}{2}[/tex]
9 = [tex]\frac{3x}{2}[/tex]
2 · 9 = · [tex]\frac{3x}{2}[/tex]

Answer:
684 m.
Step-by-step explanation:
First you divide the shape into one rectangle and one square. You first multiply 18 x 18 for the square to find the area, which equals to 324. Then you do 18 x 30, as the sides are equal. this equals to 540. Now, you add up 324 and 540. You will get the total of 684.

Explanation: to find the volume of the cone you would have to use the formula:
1/3* pi* r^2* h
If the dimensions are to be plugged in the formula would then be
1/3* 3.14* 4^2 * 12
Therefor the volume of the cone is 201.06 in^3
Moving on to the cylinder, the formula used would be
V=Bh
To find B the formula used would be
B= pi* r^2
Plugged in the formula would turn unto
B= 3.14* 3^2
The volume of the cylinder is 226.19
When subtracted, the area if the cylinder is about 25 cubic inches less than the cone, so the answer is D.
