Frank the earth, llc signed a three-year lease for office space. This lease is considered an what?
Answer: Long-term Liability
Step-by-step explanation:
This question relates to the classification of the lease above in accounting.
A long term liability is a payment that is owed by a company for a period lasting more than a year.
When a lease is for more than a year as is the case here, you take the present value of the lease and consider that amount to be a long term liability because it would represent an amount that the company is to pay for more than a single period.,

Answer:
105 students and 150 guests
Step-by-step explanation:
equation to find the answer are
1x + 5y = 855
x + y = 255
with
x + y = 255
x = 255 - y
now we replace x with (255 - y) into 1x + 5y = 855 to find y
1(255 - y) + 5y = 855
255 - y + 5y = 855
255 + 4y = 855
4y = 855 - 255
4y = 600
y = 150 (number of guests)
now we got y = 150, let's find x
x + y = 255
x + 150 = 255
x = 255 - 150
x = 105 (number of students)

Which transformation would take Figure A to Figure B
Answer:
6 squares to right and 6 squares down
Step-by-step explanation:
Go with the coordinate (-1, 5) on shape A
Hope it helps :)
Move 6 squares to right and 6 squares down.
The initial coordinate that is the x value is -5 and the transformation figure has x value 5.
So move figure A 6 squares to the right . And then move 6 squares to the down we get the transformation figure B.
Therefore, by moving 6 squares to right and 6 squares to down we get the transformation figure B.

What is the surface area?
Answer:

Step-by-step explanation:sorry if im wrong because if i am then i did incorrect math
Answer:
152 yards
Step-by-step explanation:
If you look at the rectangular side, the length is 8, and the width is 5.
The area of this side is 40 yd!
Since this is a 3D shape, there are two of that side.
40 times 2 = 80
Next, the triangle side!
The area of a triangle is base times height divided by 2.
So, this triangle is:
6 times 4 divided by 2 = 12
The area of one triangle side is 12, but there's two!
12 times 2 = 24
Lastly, there's a bottom. 6 times 8 = 48.
Now add them up!
152 yards

Christina wants to buy shirts that cost $17.00 each. If x represents the number of shirts Christina buys, which equation shows the amount of money (M) she will pay for the shirts?
Answer: 17x
Step-by-step explanation:
From the question, we are informed that Christina wants to buy shirts that cost $17.00 each and we are further told that x represents the number of shirts Christina buys.
The equation shows the amount of money (M) she will pay for the shirts will be gotten by multiplying the amount of the each shirt by the total number of shirts bought. This will be:
= 17 × x
M = 17x

Hudson is selling water bottles at a baseball game to help raise money for new uniforms. Before the game, he buys two cases of 24 water bottles for a total of $18.50. At the game, he sells all of the bottles for $1.25 each. How much profit does Hudson make?
Answer:
12.50
Step-by-step explanation:
1.25x 24= 30
30
-
18.50
____
12.50
Number of water bottles Hudson buys :
[tex] =\tt 24 \times 2[/tex]
[tex] = \tt48[/tex]
Thus, Hudson buys 48 water bottles.
Cost price of 48 water bottles = 18.50
Cost price of 1 water bottle :
[tex] =\tt \frac{18.50}{48} [/tex]
[tex]\color{plum} =\tt \$0.38[/tex]
Thus, cost price of one water bottle = $0.38
Selling price of one water bottle = $1.25
Selling price of 48 water bottles :
[tex] = \tt48 \times 1.25[/tex]
[tex]\color{plum}=\tt \$60[/tex]
Thus, selling price of 24 water bottles = $60
Which means :
▪︎Cost price = $18.50
▪︎Selling price = $60
Profit = Selling price - Cost price :
Profit Hudson made :
[tex] =\tt 60 - 18.50[/tex]
[tex]\color{plum} = \tt\$41.5[/tex]
Thus, profit Hudson made = $41.5
We know that :
[tex]\color{hotpink}\tt \: Profit \: Percentage =\color{plum} \frac{profit \times 100}{cost \: price} [/tex]
Percentage of profit Hudson made :
[tex] =\tt\frac{41.5 \times 100}{18.50 \times 100} [/tex]
[tex] =\tt \frac{4150}{1850} [/tex]
[tex]\color{plum} =\tt 2.24\%[/tex]
Thus, percentage of profit Hudson earned = 2.24%
Therefore,● Profit Hudson made = $41.5
● Percentage of profit Hudson made = 2.24%

Answer:
1.22
53.08
Step-by-step explanation:
4. We can find the quarter circle, we can find the whole triangle, lets do that
The circle is, 1/4*(1)^2*pi, which is 1/4pi
The triangle is, 2 * 2 divided by 2, which is 2
2 - 1/4pi gives us the shaded part or
2 - 1/4*3.14
2 - 0.785 = 1.215 rounded to 1.22
5. The area of a cylinder is pir^2h. r is 10, h is 1.2
12pi cm^3
we have 20 m^3 which is 2000 cm^3
Let's divide,
2000/37.68 = 53.078, rounded gives us 53.08

Answer:
DF = 28 units
AC = 64 units
CF = 32 units
Step-by-step explanation:
In the given triangle ABC points D, E and F are the midpoints of the sides AB, BC and AC.
By midsegment theorem,
"Segment joining the midpoints of each side is parallel and measure the half of the opposite side"
DF = [tex]\frac{1}{2}(BC)[/tex]
= [tex]\frac{56}{2}[/tex]
= 28 units
AC = 2(DE)
= 2 × 32
= 64 units
CF = [tex]\frac{1}{2}(AC)[/tex]
= [tex]\frac{64}{2}[/tex]
= 32 units
