Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
On a scale drawing of an office space floor plan, 1 inch represents 3 feet. Then the scale factor is given as,
Scale factor = 3 / 1
Scale factor = 3 feet per inches
The length of the copier room measures 7 inches. Then the number of feet that represents 7 inches is given as,
⇒ 7 x 3
⇒ 21 feet
The number of feet that represents the length of the copier room measures 7 inches on the floor plan will be 21 feet.

Answer:
25% or more
Step-by-step explanation:
t1 = d1/v1 , t2 = d2/v2.
d1 = d2 , and v1 = 0.8 v2
t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )
t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25

Answer:
x = 20
Step-by-step explanation:
First, we need to combine both equations as we know they are create a "straight angle", which is 180 degrees:
2x + 8 + 6x + 12 = 180
Next, we can combine like terms to simplify the equation:
8x + 20 = 180
Now, we can subtract 20 from each side:
8x = 160
Finally, we divide both sides by 8 to find the value of "x":
x = 20

You play the following game with a friend. You share a pile of chips, and you take turnsremoving between one and four chips from the pile. (In particular, at least one chip must beremoved on each turn.) The game ends when the last chip is removed from the pile; the onewho removes it is the loser.It is your turn, and there are 2014 chips in the pile. How many chips should you remove toguarantee that you win, assuming you then make the best moves until the game is over
Answer:
Each time, a person takes 1, 2, 3, or 4 chips. The strategy for a player to win the game is taking the number of chips so that the number of chips left is the form of 5k + 1 .
If It is my turn, and there are 2014 chips in the pile, I shoud take 3 chips and the left is 2011 (=5.k +1). And if the opponent takes x chips (x = 1, 2, 3, 4) , i win take 5 - x chips to guarantee the left is always in the form 5k + 1. And finally, the opponent will take the last chip.

1. Which three lengths could be the lengths
of the sides of a triangle?
O A.12 cm, 5 cm, 7 cm
O B.10 cm, 15 cm, 24 cm
O C.9 cm, 22 cm, 11 cm
O D.21 cm, 7 cm, 6 cm
Answer:
B
Step-by-step explanation:
For three side lengths to make a triangle, the two smaller ones have to add up to be greater than the third one. This is because if they are any smaller, they won't be able to touch and form a triangle. The formula for this is a+b>c.
You can go through each answer choice and determine whether or not it would work:
A. 12, 5, and 7
5 + 7 > 12 --> 12 > 12 (NOT true)
B. 10, 15, and 24
10 + 15 > 24 --> 25 > 24 (true!)
C. 9, 22, 11
11 + 9 > 22 --> 20 > 22 (NOT true)
D. 21, 7, and 6
7 + 6 > 21 --> 13 > 21 (NOT true)
This means that the correct answer is B.

Write the equation of the line in point-slope form that goes through the points (0, 1) and (2, 7)
Answer:
point - slope form
y - 1 = 3 (x-0)
Step-by-step explanation:
step(i):-
Given points are (0,1) and (2,7)
The slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{7-1}{2-0} = \frac{6}{2} = 3[/tex]
m =3
Step(ii):-
point -slope form
y - y₁ = m(x-x₁)
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3
y - 1 = 3 (x-0)
y -1 = 3x
3x - y +1=0
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3 is 3x -y +1=0

A rectangular ballroom is being carpeted. The room measures 12 feet by 11 feet. If the carpet costs $3.60 per square foot, then what is the cost of
the carpet?
Answer:
first lets find the area of the floor.
A=l*w where l=length and w=width
Plug in the data
A=14*12
A=168ft²
If 1 square foot of carpet is 2.90$, then 168 square feet are...
1 sqft 168sqft
_______ = ________
2.90$ x$
Cross multiply
1x=487.20
divide both sides by 1
x=487.20 dollars
