How many cubes with the side lengths of 1/3 ft completely fill the prism?
Answer:
48 cubes
Step-by-step explanation:
To begin, we must find the volume of both the cube and the rectangular prism.
The volume of a cube is a side to the 3rd power.
1/3 · 1/3 · 1/3 = 1/27
The volume of a prism is l * w * h.
2/3 · 1 · 8/3 = 16/9
Now, we have the volume of a cube and the prism. Since we have the find how many cubes can fit into the prism, we must divide 16/9 by 1/27.
16/9 ÷ 1/27 = 16/9 · 27/1 = 432/9 = 48/1 = 48
Therefore, 48 cubes will fit into the prism.

Answer:
4). 3
5). 600
Step-by-step explanation:
formula of finding intrest earned is (p×r×t)/100
by putting this formulae____
( HERE p means principal , r means rate , t means time )
(p×r×t) /100= interest
(480×r×5) / 100=100.80
(336×r) / 100 = 100.80
336×r= 100.80×100
r= (100.80×100)/336
r=3
5). (p×r×t)/100=interest
(p×4×5) /100 = 120.00
p×4×5 = 120.00×100
p= 12000 / 4×5
P=12000/20
P=600

△ABC has interior angles with measures x°, 100°, and 70°, and △DEF has interior angles with measures y°, 70°, and 50°.
Using the given information, which statement is true?
The two triangles are not similar because x≠y .
The triangles are similar because they each have an interior angle with a measure 70°.
The two triangles are not similar because the interior angles are congruent but the side lengths are different.
The two triangles are not similar because y = 60 so it is impossible to have three congruent angles.
Answer:
Now, △DEF has interior angles with measures y°, 70°, and 20°.
By using angle sum property,
Now, we can say that,
"The two triangles are not similar because x≠y"
As one angle of measure 70 degree is common in both the triangles.
If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.
Therefore, the two triangles are not similar because x is not equal to
Step-by-step explanation:
Answer:
the triangles are not similar. If they were, they would have the same angles.
The interior angles are not congruent. We can rule out choice B and C.
Just because they have one equal angle does not make them similar. We can rule out D.
A is the best answer.
meth, please help meeeeeeh
Answer:
50⁰
Step-by-step explanation:
we know that sum of angles in a triangle is equal to 180⁰
on adding the angles we get
x⁰+x⁰+20⁰+x⁰+70⁰=180⁰
3x⁰+90⁰=180⁰
3x⁰=90⁰
x⁰=30⁰
Now angle R=x+20=30+20=50⁰
Answer is 50⁰

Answer:
x=10
Step-by-step explanation:
so your given an angle, 110, and another with an equation, 8x+30, which happens to be vertical to 110 degree angle meaning they are equal, so they both are equal to 110 now how do you solve for x? you simply reverse the equation that x is in, so you subtract 110-30=80, then divide by 8 giving you 10, so x=10.
Answer:
X = 10, because of the second angle's equation. 8x + 30 hints the solution. 110 - 30 is 80, and 80 / 8x In this case, x can be represented as itself is 10
Find an equivalent expression for -3(2x+5)-(x-1)
Answer:
-7x - 14
Step-by-step explanation:
By simplifying the expression:
-3(2x+5) - (x - 1)
-6x-15 -x + 1
-7x - 14
Answer:
-7x - 14
Step-by-step explanation:
You can use the distributive property to find an equivalent expression.
Distribute -3 to 2x + 5.
(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15
Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)
(-1 × x) + (-1 × -1) = -x + 1
You can simplify the expression.
(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14
I hope this helps and please mark me as brainliest!
4x-14=2x please solve need help
Answer:
7
Step-by-step explanation:
1. Subtract the 4x on both sides = -14 = -2x
2. Divide -2 on both sides to get -14/-2 = x
3. -14/-2 = 7 so 7 = x

C. Ben and Michael also participated in the long jump. Michael jumped 334 thousandths of a meter less than Kevin. Ben jumped farther than Michael but not as far as Kevin. Write a decimal to the thousandths that is greater than Michael's distance and less than Kevin's distance. Explain the reasoning you used.
Answer
Kevin jumped 1.55 meters
Ben jumped 1.445
micheal jumped 1.201
Step-by-step explanation:
The reason I used those numbers is Kevin jumped the highest, so I made him jump the farthest. Micheal jumped 334 thousandths of a meterless than Kevin so I put he jumped 1.201.
The black line represents your equation from Question 7. Compare the black and blue lines.
Include in your answer:
*Slope-intercept form (y=mx + b) of the blue line. Show or explain your work.
*Which line has the greater slope? How do you know?
Hint: Find the y-intercept. Then count up and over (y/x) to the next point on the line to determine the slope.
Answer:
The black line has the greater slope.
Step-by-step explanation:
One way to think about which line has the greater slope is to imagine (or draw) a car on top of each line driving from left to right. If the car is driving up a steeper hill then the slope is greater.
To show your work though, starting at the y-intercept on the black line, find another point that you can see well on the line such as (3, 4). To get from the y-intercept to (3,4) go up 2 and right 3 so the slope is 2/3.
For the blue line, find a point that is easy to see such as (2, 3). To get from the y-intercept to (2, 3) go up 1 and right 2 so the slope is 1/2.
(Remember slope is y/x or rise/run)
Since 2/3 is bigger than 1/2, the slope of the black line is greater.

Answer:
22x - 14
Step-by-step explanation:
pretty sure its like this..
3(4x-3)+5(2x-1)
= 3×4x + 3×(-3) + 5×2x + 5×(-1)
= 12x + (-9) + 10x + (-5)
and according to the rules of multiplying negative by positive...
= 12x - 9 + 10x - 5
combine like terms using the symbols on its left
= 12x + 10x - 9 - 5
= 22x - 14
20 POINTS) Linda has to buy stickers, erasers, and a pencil. She can only spend $3. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Linda buy 3 stickers and 2 erasers?
[Use the inequality 0.35x + 0.99y + 0.59 ≤ 3]
Yes, because the total will be $1.62
Yes, because the total will be $2.93
No, because the total will be $3.62
No, because the total will be $5.93
Answer:
No, because the total will be $3.62
Step-by-step explanation:
When we substitute with 3 and 2 shown below
0.35(3)+0.99(2)+0.59 we get 3.62, which is greater than 3 dollars.
Hope this helped<33
Answer:
Alright so the question states that "She can only spend $3."
A sticker costs $0.35
A eraser is $0.99
A pencil costs $0.59
What you are trying to find is Can Linda buy 3 stickers and 2 erasers.
So add the total value of stickers prices. You need to know what's the cost of 3 stickers and 2 erasers
0.35+0.35+0.35= 1.05+0.99+0.99 = 3.03 So she can't. Now can she buy 1 sticker, 1 eraser, and 1 pencil. So is it enough to get 1 of each item?
0.35+0.99+0.59=1.93 Yeah you can.
But is it enough for her to get 3 stickers, 2 erasers and a pencil?
We already know the cost for 3 stickers and 2 erasers is $3.03. All you need to do is add $0.59 to find the total cost. The total cost of 3 stickers and 2 erasers and a pencil is $3.62. So the answer is No, because the total will be $3.62 and her budget is $3 so she will need extra $0.62 to cover the full cost.

Jackson has a cube. Each edge of the cube is 5 centimeters long.
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?
Answer:
35.355 cm
Step-by-step explanation:
if u imagine the 3D cut triangle but at a different angle, u would imagine the legnth of the parallelogram being 7.071 which is the hypotenuse of the triangle... along with the hypotenuse given, they also gave the side lenght of the parallelogram which is 5cm... 5 x 7.071 = 35.355 cm

Cassidy is going to the county fair with her friends but can only stay at the fair for 3 hours. The fair offers two different pricing structures. Cassidy can purchase an all-day pass with unlimited rides for $45.00 or she can pay an admission fee of $9.00 and pay $4.00 for each ride. If Cassidy rides 12 rides, how much does she save by buying the all-day pass?
A. $12.00
B. $21.00
C. $They both cost the same
D. $51.00
Answer:
Option A.
Step-by-step explanation:
The all- day pass is just $45.
For the other pass, we need to do 4 x 12 + 9.
4 x 12 + 9
48 + 9
57.
57 - 45 is 12.
