Polyhedron P is a cube with a corner removed and relocated to the top of P. Polyhedron Q is a cube. How do their surface areas compare?
P
A. P’s surface area is less than Q’s surface area.
B. P’s surface area is equal to Q’s surface area.
C. P’s surface area is greater than Q’s surface area.
D. There is not enough information given to compare their surface areas.
Answer:
C. P’s surface area is greater than Q’s surface area.Step-by-step explanation:
Refer to attached
With a corner removed, it doesn't change surface area of the cube as same area is exposed equal to the area of 3 small faces.
With the corner relocated to the top of the cube, it covers the area of one small face but adds up small 5 faces (4 sides and one top). In total the P has more surface area than the Q.
Correct answer choice is C.
How do you solve this?
Answer:
so for one, just put a line horizontal to line 1
part two I'm assuming you do the same as p since it's not asking you to make it perpendicular to line 1.
part three, create going through line 1 (vertical)
part four constructs the same triangle, but just move the points a little so that way it's not overlapping.
Step-by-step explanation:
parallel means not touching
perpendicular means crossing each other paths.
How many times can 20 go in 100
Answer:
5 times
Step-by-step explanation:
Answer:
5 times
Step-by-step explanation:
So this is called division. To solve this you can either use a calculator, or you can use something called guess and check. Guess and check is what it sounds like, guessing and checking to see if it's correct or not.
The way I would solve it is just do 100/20 which equals 5. You can also just add 20 a certain amount of times. For example you could do 20 + 20 + 20 + 20 which equals 80. So that means you can add another 20 to equal 100
i need to write the inequalities helpp!!!
Answer:
1. f > 40 miles/gallon
2. t < 35 degrees
Answer:
For part one the vehicle cannot have less than 40mpg so the equality would be
[tex]f\geq 40mpg[/tex] because the mpg must be greater than or equal to 40mpg.
For part two the temp must be LESS than 35 not including 35.
so we would show that with [tex]t<35F[/tex]
Solve for y
-3=7(y-9/7)
Answer:
6/7 = y
Step-by-step explanation:
-3=7(y-9/7)
Distribute
-3= 7*y - 7*9/7
-3 = 7y - 9
Add 9 to each side
-3+9 = 7y -9+9
6 = 7y
Divide each side by 7
6/7 = 7y/7
6/7 = y

The ratio between the number of red, green and blue marbles in a box is 2:6:5. How many marbles are in the box if there are 20 fewer red marbles than green marbles?
Answer:
65 marbles
Step-by-step explanation:
2:6 = x-20:x using the information in the problem
2x = 6x-120, and therefore x = 30. 30 is the number of green marbles.
We can find that the multiplier is 30/6 = 5. So there will be 5*2 = 10 red marbles. 5*5 = 25 blue marbles.
30+10+25 = 65 marbles total.
point slope form of y=10x-82
y + 82 = 10x is the answer.
Answer:
y+72 = 10(x-1)
Step-by-step explanation:
I don't really know why this would be useful for solving a problem; please tell me in the comments of my answer.
Anyway, I would pick a random point that would satisfy this equation. One example would be (1, -72)
Now just plug those 2 numbers into the equation:
y+72 = 10(x-1)

the members of senior class are planning a dance. they use the equation s=2r+t/x to determine the total receipts. what is r in the terms of x,s and t? show all work
Answer:
r = 1/2(s -t/x)
Step-by-step explanation:
Here, we simply want to make r the subject of the formula;
We proceed as follows;
s = 2r + t/x
s - t/x = 2r
Divide both sides by 2
r = 1/2(s - t/x)

Step-by-step explanation:
Eli wants to combine 0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution. He needs to determine how many gallons of 35% solution are needed.
Eli decides to let v represent the volume of the 35% solution and makes a table to help solve the problem.
Help Eli by completing the table.
Answer:
Here you go :)
Step-by-step explanation:
0.0125 gallons of 35% solution is needed.
Given that,
Eli wants to combine 0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.
Eli decides to let v represent the volume of the 35% solution.
We have to find,
How many gallons of 35% solution is needed?
According to the question,
Eli decides to let v represent the volume of the 35% solution.
And 0.5 gallons of 10% acid solution,
the volume of the 15% acid solution is (v +0.5).
Therefore,
0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.
[tex]\rm = 0.5 \times \dfrac{10}{100} + v \times \dfrac{35}{100} = (v+0.5) \times \dfrac{15}{100}\\\\= 0.5 \times 0.01 + v \times 0.35 = (v+0.5) \times 0.15\\\\= 0.05 + 0.35v = 0.15v + 0.075\\\\= 0.35v - 0.15v = 0.075 -0.05\\\\= 0.20v = 0.025\\\\v = \dfrac{0.025}{0.20}\\\\v = 0.0125[/tex]
Hence, 0.0125 gallons of 35% solution is needed.

1. 3D line test
2.diagonal line test

4.vertical line test
Answer:
i picked d because
Step-by-step explanation:
The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.
A video store changes a monthly membership fee of $7.50 but the charge to rent each movie is only $1.00 per movie another store has no membership fee but it cost $2.50 to rent each movie how many movies need to be ready each month for the total fees to be the same from either company
Answer:
5 movies
Step-by-step explanation:
Let x denotes number of movies that need to be ready each month for the total fees to be the same from either company.
Monthly membership fee charged by a video store = $7.50
Amount charged to rent each movie = $1.00
So,
total amount charged by the first store = [tex]7.50+(1)x=7.50+x[/tex]
Monthly membership fee charged by another video store = $0
Amount charged to rent each movie = $2.50
So,
total amount charged by another store = [tex]0+2.50(x)=2.50x[/tex]
To find number of movies that need to be ready each month for the total fees to be the same from either company,
solve [tex]7.50+x=2.50x[/tex]
[tex]7.50+x=2.50x\\7.50=2.50x-x\\7.50=1.50x\\x=\frac{7.50}{1.50}\\ =5[/tex]

(0,11) (3,50) x is measured in gallons and y is measured in miles. Find the rate of change in y relative to x for the ordered pairs. Include unit of measurement in your answer.
Answer:
[tex]y=13\text{ miles per gallon}[/tex]
Step-by-step explanation:
We have the two points: (0, 11) and (3, 50).
And we want to find the rate of change in y relative to x, where x is the gallons and y is the miles.
In simple terms, we want to find the slope between the two points.
So, let's use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, 11) be (x₁, y₁) and let (3, 50) be (x₂, y₂). Substitute. Let's also put "miles" in the numerator with the Ys and "gallons" in the denominator with the Xs. This yields:
[tex]y=\frac{50-11\text{ miles}}{3-0\text{ gallons}}[/tex]
Subtract and reduce:
[tex]y=39\text{ miles}/3\text{ gallons}=13\text{ miles per gallon}[/tex]
And we're done!
