Answer: The surface area of the cube would be 3^3/4.
Step-by-step explanation:
A cube has 6 faces [ 6 surfaces ]. Each surface has a square shape.
The area of 1 surface= (side)^2= 3/4 · 3/4= 9/16 sqr.in.
Surface area of cube =9/16 · 1/6= 54/16.
divide both top and bottom (54 and 16) by 2. you should end up with 27/8.
27/8 = 3^3/4 sqr. in.
Hope this helps.

Given that x = 9.5 m and θ = 20°, work out AC rounded to 3 SF
Answer:
AC ≈ 10.1 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos20° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{9.5}{AC}[/tex] ( multiply both sides by 9.5 )
AC × cos20° = 9.5 ( divide both sides by cos20° )
AC = [tex]\frac{9.5}{cos20}[/tex] ≈ 10.1 m ( to 3 sf )
Seven friends share 3 bags of trail mix equally. What fraction of a bag of trail mix does each friend get? Each friend will receive of a bag of trail mix.
Answer:
Step-by-step explanation:
There are 3 bags to be shared among 7 people.
Therefore each person will get 3/7 bags.
I couldn't think of a way of explaining the question in terms of bags when I wrote my answer. Suppose you try this.
Weigh each bag separately.
Add the weights (or masses) together.
Divide by 7
Another way is to weigh each bag separately. There are three bags and seven people. Each person will get 3 parts of the total divided by 7.
This will solve the problem in a practical manner. Give the Brainliest to the other responder who did a much better job of explaining it than I have.
Answer:
[tex]\frac{7}{3}[/tex] or 2[tex]\frac{1}{3}[/tex] of a bag of trail mix
Step-by-step explanation:
To find the fraction of trail mix each friend will get, divide the number of friends by the number of bags of trail mix:
Since there are 7 friends and 3 bags of trail mix, the fraction will be [tex]\frac{7}{3}[/tex]
This can also be simplified to a mixed fraction, 2[tex]\frac{1}{3}[/tex]
So, each friend will receive [tex]\frac{7}{3}[/tex] or 2[tex]\frac{1}{3}[/tex] of a bag of trail mix.

If 25 percent of your classmates have cats, and your class has 20 students, how many students have cats? (I have to show my work)
Answer:
5 students.
Step-by-step explanation:
25% is a quarter of the amount, or 1/4. A quarter of 20 is 5, since 4 times 5 is 20. So 5 students have cats.
Last night, Jasmine and her family went out for dinner. The questions below came up on their way to the restaurant or during the meal. Decide whether or not each question is a statistical question. Select all that apply.
●How far are we from the restaurant?
●How long will it be until we get there? ●Would you rather have burgers or pizza?
●How much should we leave for the tip? ●What was the most frequently ordered dish in the restaurant this evening?
●Did you like the pizza tonight?
●Which table's bill was the highest?
●How many people were sitting at each table this evening?
A statistical question is a question where the data collected can vary.
Ex. Statistical - "How old are the students in my class?" The data can vary based on which student you ask.
The following questions are statistical:
●Would you rather have burgers or pizza?
●How much should we leave for the tip?
●Did you like the pizza tonight?
●How many people were sitting at each table this evening?

 A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and a height of 60 centimeters. If the company used 54,259.2 cm3 of steel, how many rods did it make? Use 3.14 do not round your answer +Help me plz
Answer:
72 rods
Step-by-step explanation:
First, find the volume of each rod, using the formula V = [tex]\pi[/tex]r²h
Plug in pi, the radius, and height, and solve:
V = [tex]\pi[/tex]r²h
V = (3.14)(2²)(60)
V = (3.14)(4)(60)
V = 753.6
So, each rod has 753.6 cm³ of steel.
Divide 54,259.2 by this to find how many rods it will make:
54,259.2 / 753.6
= 72
So, it will make 72 rods.
What is the difference between the number of solutions for a two-step equation and for a two-step inequality
Answer:
A two-step equation is something like:
A*X + B = C
In this case, like in a linear equation, we have only one solution that can be found as:
A*X = C - B
X = (C - B)/A
In the case of a two-step inequality, we have something like:
A*X + B > C
Solving this we get;
A*X > C - B
X > (C - B)/A
In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.
That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.

In science class, Farah uses a graduated cylinder with
water in it to measure the volume of some marbles. She
drops in marbles so that they're all under water and
measures the height of the water.
After dropping in 4 marbles, the height is 10 ml
After dropping in 6 marbles, the height is 11 ml.
Here are your answers from the previous screen:
Before dropping in any marbles, the height is 8 ml.
Each marble increases the height by 3 mL.
What should be the height of the water after 13 marbles
are dropped in?
Answer:
47 mL
Step-by-step explanation:
Note each marble increases the height by 3 mL, and we start with 8 mL, so we multiply 3 by 13, and add it to 8
The volume of each marble is 0.5 ml. The volume after dropping 13 marbles is 14.5 ml.
VolumeThe volume of an object is the amount of space occupied by a three dimensional object.
A graduated cylinder can be used to measure the volume of a cylinder. Given that After dropping in 4 marbles, the height is 10 ml and After dropping in 6 marbles, the height is 11 ml.
Hence:
Volume per marble = (11 ml - 10 ml) / (6 - 4) = 0.5 ml
The volume of each marble is 0.5 ml.
If the initial volume is 8 ml, after 13 marbles, height = (8 ml + 0.5 * 13) = 14.5 ml.

Megan is the manager of a computer shop she organises a sale with 18% off all tables Megan changes the price of own table from £389 to £330.98 has Megan changed the price probably
Answer:
this is easy. all you have to do is figure out what 18% of 389 is and then subtract that answer from 389. the easy trick i use is to make a fraction with the numerator being a question mark and the denominator being 389 (displayed below). then you would make a second fraction with 18 as the numerator and 100 being the denominator (displayed below). you would then multiply 389 with 18 and divide by 100 to get the numerator of the first fraction (which is 70.02). now you subtract 70.02 from 389 (being 318.98). this would mean that Megan has not done the math correctly.
Step-by-step explanation:
?/389 = 18/100
389 x 18 = 7002
100/7002 = 70.02
389 - 70.02 = 318.98
