The Answer Is 3a^2 3b^2 3c^2
Since all the variables equal each other, you may pick one variable to copy in the equation.
[tex] {a}^{2} + a^{2} + {a}^{2} = 3 {a}^{2} [/tex]
And since they're the same numbers, squaring a will have no effect in the equation.

A video game originally costs $63, but if you buy it before the end of May there is a 25% off sale. The sales tax is 9.5%. What is the final price of the video game if you buy it before the end of May?
Answer: $53.24
Step-by-step explanation:
Find the sales tax:
9.5*63.00=598.5
Then divide 598.5 by 100: 598.5/100= 5.985
Round: $5.99 ( sale tax amount )
Now we find the discount: 25*63.00= 1,575
Then divide it by 100 : 1,575/100= $15.75 ( discount amount )
Take the original price of the game and subtract it by the discount amount, then add the sales tax amount: 63.00-15.75= 47.25+5.99= $53.24
Answer: $53.24

A rectangle with a length of 22 feet and an unkown width,W, has a perimeter of 74 feet. Set up and slove an equation to find the vaulur of W
Answer: W=15
Step-by-step explanation: The equation you set up is 2(L) + 2(W)=74
2(22) + 2W=74
44+2W=74
Subtract 44 from both sides
2W=30
Divide both sides by 2
W=15
2) A block of cheese weighs 0.6 kg. The block is cut into smaller pieces. Each piece weighs 0.05 kg. How many pieces are there? (Show the division equation to solve for this word problem before showing multiplication to solve.)
Answer:
12
0.6/0.05
(0.6 x 100) / (0.05 x 100)
= 60/5 = 12
Step-by-step explanation:
number of pieces = total weight of the cheese / weight of each piece
0.6 / 0.05
to divide easily, convert the decimals to whole number by multiply both the denominator and numerator by 100
(0.6 x 100) / (0.05 x 100)
= 60/5 = 12
The funnel is filled with oil. How many quarts of oil are in the funnel? 3 1 qt 58 in. Round your answer to the nearest tenth.
Answer:
There is 2.887 quarts of oil in the funnel
Step-by-step explanation:
Complete question
A funnel is in the shape of a cone with a radius of 4 inches and a height of
10 inches. The funnel is filled with oil. How many quarts of oil are in the funnel?
Solution
As we know, volume of the cone is given by
[tex]V = \frac{1}{3} \pi r^2 h[/tex]
Here,
V = volume of the cone
r is the radius of the base of the cone
h is the height of the cone
Substituting the given values in above equation, we get -
[tex]V = \frac{1}{3} *3.14*4*4*10\\V = 167.467[/tex] Cubic inch
As given
1 quarts = 58 cubic inch
Total number of quarts of oil
[tex]\frac{167.467}{58} \\2.887[/tex]
There is 2.887 quarts of oil in the funnel

What is the simplified expression for given expression?
In the given expression [tex]\cos6x[/tex] can be break as [tex]\cos(2\cdot3x)[/tex].
Now use the identity [tex]\cos2x=2\cos^{2} x-1[/tex] in the given expression.
[tex]1-\cos6x=1-2\cos^{2}{3x}+1[/tex]
[tex]=2(1-\cos^{2}{3x})[/tex]
Now use the identity [tex]1-\cos^{2}x=\sin^{2}x[/tex].
[tex]1-\cos6x=2\sin^{2}{3x}[/tex].
Therefore, the given expression is equivalent to [tex]2\sin^{2}{3x}[/tex].

A new truck sells for $29,000 and depreciates 12% each year. Find the value of the truck after 10 years.
Answer:
according to the question value got less 12% each year
first of all the 12% of 29000$ = 29000÷100×12= 3480 $
in one year truck value deprecates 3480$
in 10 years it will 3480$×10 =34800$
now truck cost will be = 29000-34800$= -5000$

Netflix charges David $15 per month for a membership, plus a one time $5 fee to stream on his phone. How many months will David have his membership if Netflix charges David $50?
Answer:
David will have his membership for 3 months.
Step-by-step explanation:
For the first month + the one-time mobile fee, that is $15 for one month + $5 for the fee.
So far, he has been charged $20.
Another month's cost is $15 more, which will bring his total cost to $35.
Another month's cost is $15 more, which will bring his total cost to $50.
If Netflix charges David $50, that means he will have paid the mobile fee, and have had his membership for 3 months.
Kelly's team won 85% of the games they played in a season. The team lost 12 games. How many games did Kelly's team win in the season?
Answer:
68 games
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Games won = 85%
Game lost = 12
Here, 100% - 85% = 12
15% = 12
or 1% = 0.8
So, total games played (100%) = 80 games
Now, number of games won = Total games - Games lost
= 80 - 12
= 68 games
Hence, Kelly's team wins 68 games in the season.
What is the volume of the pyramid? 2.4 cm3 3.6 cm3 4.8 cm3 7.2 cm3
Answer:
C 4.8cm^3
Step-by-step explanation:
The volume of the pyramid is 4.8 cm³.
Given that a pyramid with base side length is 2 cm, we need to find the volume of the pyramid,
Volume of a pyramid = 1/3 × base area × height
So,
We have ∠ABC = 45°, in right triangle ΔACB,
Since ∠ABC = 45° therefore, ∠BAC = 45°,
So, AC = BC = 3.6 cm,
So, the volume = 1/3 × 2² × 3.6
= 4 × 1.2
= 4.8
Hence the volume of the pyramid is 4.8 cm³.

Find the perimeter of a rectangle with length (x-5) and width (3x+1).
Answer:
8x-8
Step-by-step explanation:
P=s+s+s+s or in this case P= 2l+2w
P= 2(x-5)+2(3x+1)
P=(2x-10)+(6x+2)
P=8x-8
8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1).
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given that,
Length of rectangle = x - 5
Width of rectangle = 3x + 1
Now,
Perimeter of rectangle = 2(width + length)
Perimeter of rectangle = 2(3x + 1 + x - 5)
The perimeter of the rectangle = 8x - 8
Hence "8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1)".

Choose an equivalent system of equations to the following system:
Fx + Gy = H
Qx + Ry = S
6Fx + Gy = 6H
Qx + 6Ry = S
6Fx + 6Gy = 6H
Qx + Ry = S
Fx + 6Gy = 6H
Qx + Ry = S
6Fx + 6Gy = 6H
Qx − Ry = S
Answer:
B. 6Fx + 6Gy = 6H
Qx + Ry = S
Step-by-step explanation:
Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.

A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.
B: the correct choice
C: see A.
D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.
