I tried getting the answer twice and both times I got 228, which the teacher said was wrong.
(each cube is one inch squared)
Step-by-step explanation:
the answer shoukd be 324
because in cube there are 6 sides
and one side contain 54 box

85, 58, 72, 85, 46, 93 Mean:? Median:? Mode:? Range:?
Answer:
Mean is 73.2. Median is 85. Mode is 85. Range is 47.
Step-by-step explanation:
First order the numbers. 46, 58, 72, 85, 85, 93. The mode is all of these numbers added up to get 439. divided by the amount of numbers there are. there are 6. so 439 divided by 6 is 73.166 or 73.2. Median is the middle of the data set which is 85. the mode is the number that appears the most in a data set which is also 85. the range is the highest number minus the lowest number so we get 93 - 46 to get 47.
Answer:
Step-by-step explanation:mode 85

Last year, rusty’s tools experienced $67,550 in net sales, creating a gross profit of $50,338. if rusty had a total operating expense of $35,200 last year, what was his net profit margin? a. 22.4% b. 52.1% c. 74.5% d. 79.0%
The Net profit margin is 22.41%
Rusty's Tool experienced $67550 in net sales, creating a gross profit of $50338.
If Rusty had a total operating expense of $35200 then we have to find the net profit margin.
Since profit $50338 includes the operating expense of $35300 then net profit will be
= $50338 - $33500
= $15138
Now the selling price is given as $67550.
What is the formula for profit margin?
Profit margin = (Net profit/selling price) 100
Profit margin =151.38/675.50=22.41 %
Therefore, the answer is profit margin = 22.41%.

Melissa is driving a sports utility vehicle along the interstate at a constant speed of 55 mph. A sports car one-half mile behind her that is moving at a constant speed passes her in 60 seconds. How many miles per hour is the speed of the sports car
Using proportions, it is found that the speed of the sports car is of 85 miles per hour.
What is a proportion?A proportion is a fraction of a total amount.
The cars are moving in the same direction, hence their relative speed is the difference of them.
The sports car is 0.5 miles faster over one minute, hence over one hour the difference is:
60 x 0.5 = 30 miles per hour.
Considering that the utility vehicle has a speed of 55 mph, the speed of the sports car is given by:
55 + 30 = 85 miles per hour.

3x2-9=0 GCF. It’s Precalculus btw
Answer:
x = ± [tex]\sqrt{3}[/tex]
Step-by-step explanation:
3x² - 9 = 0 ( add 9 to both sides )
3x² = 9 ( divide both sides by 3 )
x² = 3 ( take square root of both sides )
x = ± [tex]\sqrt{3}[/tex]
or
3x² - 9 = 0 ← factor out 3 from each term
3(x² - 3) = 0
equate x² - 3 to zero and solve for x
x² - 3 = 0 ( add 3 to both sides )
x² = 3 ( take square root of both sides )
x = ± [tex]\sqrt{3}[/tex]

Donald bought 2 game controllers at Gamestop for $36. Each one cost the same amount. What is the unit rate for a single controller? & Jake was offered the following amounts of an entire pizza: 0.6, 4/5, or 0.75. Jake really likes pizza and wants the largest amount of pizza he can get. Which of the amounts should he select?
Don’t add all together
There’s two answers
Answer:
Answer to question 1 is 18
Answer to question 2 is 4/5
Step-by-step explanation:
Question one simply asks how much one controller is
Being that both controllers = 36$
And to find one controller price you would just divide the price by the number of units
36/2= 18
The second question asks how much pizza would be more .6, 4/5 or .8, or .75
Since .8 has the most value or in this case pizza 4/5ths is the answer

What is the capacity of a cylinder if it’s 2.60m high and has a diameter of 160.0cm
Answer:
Step-by-step explanation:
pi = 3.14
h = 2.60 m
d = 160.0 cm
Radius
r = d/2
r = 160.0 / 2
r = 80.0 cm
height
There are 100 cm in 1 meter. The units have to agree.
2.6 m * 100 cm / m
2.6 * 100 = 260 cm
Formula
V = pi * r^2 * h
V = 3.14 * 80^2 * 260
V = 5224960 cm^3
If you want a more manageable number, you could convert this into m^3
That's done by
V = 5224960 / 1000000 = 5.22 m^3

Nic is making chocolate chip cookies. The recipe requires 3/4 cups of brown sugar and 1 1/8 teaspoons of salt. Nic wants to make the recipe using 1 cup of brown sugar. To maintain the ratio, how much salt is required when 1 cup of brown sugar is used?
To maintain the ratio, the amount of salt required when 1 cup of brown sugar is used is 1.5teaspoon
Ratio and proportion
Fractions are written as a ratio of two integers.
From the gven question, we are told that a recipe requires 3/4 cups of brown sugar and 1 1/8 teaspoons of salt, this can be expressed as:
3/4 cups = 1 1/8 teaspoons
To maintain the ratio, the amount of salt that is required when 1 cup of brown sugar is used is given as:
amount of salt required = (1 1/8)/3/4
amount of salt required =9/8 * 4/3
amount of salt required = 3/2
amount of salt required = 1 1/2 teaspoon
Hence to maintain the ratio, the amount of salt required when 1 cup of brown sugar is used is 1.5teaspoon

Liz flips a coin 60 times. The coin lands heads up 36 times and tails up 24 times. Complete each statement.
Answer: 58.33%
Step-by-step explanation:
So, Liz flipped the coin a total of 60 times
Let this be the denominator.
Probability of coin landing up: 35/60
Probability of coin landing down: 24/60
We need the probability of the coin landing up.
So, convert 35/60 into a percentage
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 1003560 × 100100= (35 × 10060) × 1100 = 58.33/100

Please give how to solve every step
☆ Thank you ☆
Answer:
x = a/7
Step-by-step explanation:
Area is length x width, so let's call our unknown, the length, x
So the total area is 7 (the width) times x
If the total area is a, then we can write the equation a = 7(x)
Next, we have to isolate the variable for the length, x
To do this, we divide both sides by 7, leaving a/7 = x, or x = a/7
what is the length of the line segment that has the endpoints A (-3,2) and B (1,0)
Distance measure how far an object have gone. The length of the line segment that has the endpoints A (-3,2) and B (1,0) is 2√5.
How to calculate the distance between two pointsThe formula for calculating the distance between two coordinates is expressed as:
D = √(x2-x1)²+(y2-y1)²
Given the coordinate points A (-3,2) and B (1,0), the length of the line segment that has the endpoint is given as:
D = √(0-2)²+(1+3)²
D = √(2)²+(4)²
D = √16+4
D=√20
D = 2√5
Hence the length of the line segment that has the endpoints A (-3,2) and B (1,0) is 2√5
