Arusha decides to build the prism using two cubes with edge lengths of 5 centimeters. She will partially fill the prism with 150 cubic centimeters of sand. What fraction of the prism's volume will bring filled by the sand? Show your work
Using the volume of the cube, it is found that the fraction of the prism's volume will bring filled by the sand is of [tex]\frac{3}{5}[/tex].
What is the volume of a cube?The volume of a cube of edge length l is given by:
V = l³.
In this problem, there are two cubes, each with edge length of l = 5 cm, hence, the total volume is given by:
V = 2 x l³ = 2 x (5 cm)³ = 250 cm³.
150 cm³ will be filled with sand, hence the fraction is given by:
[tex]\frac{150}{250} = \frac{15}{25} = \frac{3}{5}[/tex]

Answer:
Mode: 7
Range: 6
Step-by-step explanation:
Think of the M and O in "mode" as "most often." The mode is the number that appears more than any other.
Range is the difference (subtraction) between the smallest number and largest number in the data. So we have 3, 5, 5, 7, 7, 7, 7, 7, 8, 8, and 9. We take the largest number, 9, and subtract the smallest number, 3, from it.
9-3 = 6
In the future, if you come across "median," that means to put all of the numbers in order from least to greatest and whatever number is in the middle will be the median. Think of the median of a road, which is at the center. The median in this data set would be 7. If you have two different numbers in the center, find the number between those two. For example: if the two median numbers were 7 and 8, the median would be 7.5.
The mean is the sum of all of the numbers, divided by two. So for this data set, you would do 3+5+5+7+7+7+7+7+8+8+9. Then, you would take the total and divide it by 2.
73 / 2 = 36.5

Fill in the missing reasons for the following two-column proof for the following information. given: m is the midpoint of cd; cm = 3x – 10; md = 6x – 22 prove: x = 4 statement reason m is the midpoint of cd; cm = 3x – 10 ; md = 6x - 22 1. ? cm = md 2. ? 3x – 10 = 6x – 22 substitution -3x – 10 = -22 subtraction property of equality -3x = -12 3. ? x = 4 division property of equality
Midpoint is the middle segment of a given line. Since md = cm = 2 hence the point m is the midpoint of cd
How to prove the midpoint of a line?A line is a distance between two points. Given the line cd with "m" as the midpoint, the distance between cm and md will be equal that is:
md = cm
Given the following parameters
md = 6x - 22
cm = 3x - 10
Equate both expressions
6x - 22 = 3x - 10
6x - 3x = -10 + 22
3x = 12
x = 4
subtitute
cm = 3x - 10
cm = 3(4) - 10
cm =
Similarly:
md = 6x -22
md = 6(4) --22

Answer:
164.
Step-by-step explanation:
We can break this shape into a rectangle and a trapezoid.
Area for a rectangle is l x w, or in this case, 8 x 16.
8 x 16 = 128, so the rectangle’s area is 128.
Area for a trapezoid is ((a+b)/2)h.
We do not have all the info we need to solve this equation yet. We need the measurement of two sides of the trapezoid. This is 16 - 12, or 4. The other side of the trapezoid we need to find is 16 - 8, or 8.
Now we can plug in the numbers.
((8 + 10)/2)4
(18/2)4
9 x 4
36
Now we can add up the areas of both shapes to find the answer.
36 + 128 = 164, so the answer is 164.
Answer:164
Step-by-step explanation:
step 1: divide the irregular shape into regular shapes in this case Triangle and two rectangles
step 2: Calculate the individual areas for the shapes the area of the rectangle is (128) because the sides 16 and 8 add up to 128 as area.For the smaller rectangle the area is (32) since 8 times 4 is equal to 32 and lastly for the triangle the area is four since the base of 2 times the height of 4 equals 8 and 8 divided by two is 4 so the are of the triangle is (4)
step 3: Combine all the areas 128+32+4=64 therefore the area for the irregular figure is (164)

Given that

g(x) = (10x + 7) - (6x + 2)
g(x) = 4x + 5

We'll have rectangles to represent the four categories mentioned in the table. The height of each rectangle (known as a "bar") represents the number of people in that particular category.
For example, we have 11 people who rated their visit as "poor", so the bar labeled "poor" will be 11 units tall. The same will apply to the other bars.
Pay special attention there are gaps between adjacent bars. This is in contrast to a histogram where there are no gaps. This is simply a style choice.

is (x+5) A FACTOR OF f(x) = x3 − 4x2 + 3x + 7
Answer:
(x+5) is not a factor of f(x)
Step-by-step explanation:
Step 1 : we solve the equation x +5 = 0
x + 5 = 0 then x = -5
Step 2: we plug in -5 into f(x)
If we get zero then x+5 is a factor of f(x)
If we get a number other than zero then x+5 is not a factor of f(x)
Calculation:
f(-5) = (-5)³ − 4(-5)² + 3(-5) + 7 = - 233
Since we got -233 and not 0
Therefore ,(x+5) is not a factor of f(x)
Answer:
(x + 5) is not a factor of f(x) = x^3 - 4x^2 + 3x + 7
Step-by-step explanation:
To see if (x + 5) is a factor, you can use either synthetic division or long division.
I'll be using synthetic division to divide f(x) by (x + 5):
-5 | 1 -4 3 7
| -5 45 -240
---------------------
1 -9 48 -233
The remainder is -233, which means that (x + 5) is not a factor of f(x) since there is a remainder.
Therefore, (x + 5) is not a factor of f(x) = x^3 - 4x^2 + 3x + 7.
The dimensions of a rectangular garden were 5 m by 12 m. Each dimension was increased by the same amount. The garden then had an area of 120 m2. Find the dimensions of the new garden.
if dimensions were 5 and 12, that means ratio was 5:12. if we increase wach dimension by the same amount, the ratio is the same.
so:
5x×12x=120
60x²=120
x²=120÷60
x²=2
x=√2
that means each dimension was increased by √2
so dimensions are: 5√2 and 12√2
