ANALYZE The surface area of a three-dimensional object is the sum of the area of the faces. If represents the length of the side of a cube, write a formula for the surface area S of the cube.
Step-by-step explanation:
If X represents the length of the side of a cube, the formula for the surface area of the cube, S =?
solution :
the area of each face of the cube = side × side
= X × X = X²
the cube has 6 similar faces, so the surface area of the cube could be:
S = 6 × X² = 6X²
Answer:
Surface Area = 6 × S²
Step-by-step explanation:
the surface area fo the cube :
SA = 6 × lenght × lenghtif lenght = S, the surface area fo the cube :
SA = 6 × lenght × lenght
SA = 6 × S × S
SA = 6 × S²

Tony bought a $48 sweatshirt and used a coupon for a 10% discount. Keith bought an identical sweatshirt at a different store for $42.95. Which statement is true?
Answer:
Keith paid $0.25 less than Tony paid.
Step-by-step explanation:
Tony paid ($48 - 10%) = $43.2
Keith paid $42.95.
The difference is Tony paid $0.25 more, or Keith paid $0.25 less.
Answer:
Keith paid $0.25 less than Tony.
Step-by-step explanation:
Tony: 48 x 0.10 = 4.8
48 - 4.8 = $ 43.20 (Tony)
Keith: $ 42.95
43.20 - 42.95 = 0.25

What is the first step in solving 0.35 + 0.22x = 1.67?
Answer:
6
Step-by-step explanation:
0.22 x=1.67-0.35=1.32
then x=1.32/0.22=6
Answer:
You do reverse operation, so you subtract 0.35 on each side. You will end up with 0.22x = 1.32

Last night 30cm of snow fell in 6 hours. If it continues snowing at the
same rate, how long will it take for 45cm of snow to fall?
Answer: 9 hrs for 45cm of snow to fall
Step-by-step
If 30cm = 6 hrs
Then divide 30/6 to get the unit rate of the amount of snow per hr
Which is 5/1
So 5cm per hr
Then add 30+5+5+5 to get 45
And since we know 5cm equal 1 hr
Add the original amount of hours which is 6 plus 3 ones
Which is 6+1+1+1
In total, it will take 9 hrs for 45cm of snow to fall.

3x²-x+1 is a factor of ax⁴+bx³+12x² - 6x + 1 . Then a-b equals
Answer:
a-b = 31 (a ≠ b)
Step-by-step explanation:
(3x²-x+1)(px²+qx+1) = ax⁴+bx³+12x² - 6x + 1
3px⁴+(3q-p)x³+(3+p-q)x²+(q-1)x+1 = ax⁴+bx³+12x² - 6x + 1
q-1 = -6 q = -5
3+p-q = 3+p-(-5) = 8+p = 12 p = 4
b = 3q-p = 3*(-5) - 4 = -19
a = 3p = 3*4 = 12
a-b = 12 - (-19) = 31

Linda walked 3/4 (or 75%) of a track which is 3.5 miles long
Multiply 0.75 by 3.5 to get 2.625 miles (or 2 and 5/8 miles)
38.
We need to multiply the 2 and 3/8 mile track by 2 and a half (2 and 0.5)
1/8 is 0.125
2/8 is 0.25
3/8 is 0.375
The track is 2.375 miles long.
Multiply 2.375 by 2.5
The track will be 5.9375 miles long after 5 years ( or 5 and 15/16 miles)
Step-by-step explanation:
37) ¾×7/2
21/8 miles = 2⅝miles .
38) (19/8×5/2)+19/8
= 95/16+19/8
= 133/16 = 8 5/16 miles .

The daily consumption C (in gallons) of diesel fuel on a farm is modeled by C = 30.3 + 21.6 sin(2Ď€t/365 + 10.9) where t is the time (in days), with t = 1 corresponding to January 1. What is the average daily fuel consumption? Which term of the model did you use? Explain.
The question is an illustration of the sine function.
The average daily fuel consumption is 30.3The vertical shift represents the average daily fuel consumptionThe function is given as:
[tex]\mathbf{C = 30.3 + 21.6\sin(\frac{2\pi t}{365} + 10.0)}[/tex]
A sine function is represented as:
[tex]\mathbf{y = a\sin(bx - c) + d}[/tex]
Where d represents the vertical shift.
In this case, d represents the average rate
So, the average daily fuel consumption is 30.3
The term that represents the average daily fuel consumption is the vertical shift of the sine function.
