Answer:
x² + y² is equal to = (4 / 81)(845m² + 78m + 18)
Step-by-step explanation:
We first need to get the values of x and y, which can be done using a system of equations, substituting one of the two functions into the other:
Given:
y = 2x + 2
3x + 3y = 26m
Then:
3x + 3(2x + 2) = 26m
3x + 6x + 6 = 26m
9x + 6 = 26m
9x = 26m - 6
x = (26m - 6) / 9
Now we can solve for y:
y = 2x + 2
y = 2(26m - 6) / 9 + 2
y = 2(26m - 6) / 9 + 18 / 9
y = (52m - 12 + 18) / 9
y = (52m + 6) / 9
Now we can sum up their squares:
x² + y²
= ((26m - 6) / 9)² + ((52m + 6) / 9)²
= (676m² - 312m + 36) / 81 + (2704m² + 624m + 36) / 81
= (3380m² + 312m + 72) / 81
= (4 / 81)(845m² + 78m + 18)

Latest Releases Depot rents DVD/Blue ray for $3.00 each and has no membership fee. Video for You rents DVD/Blue rays for $2 each but has a membership fee of $15.
Answer:
15 rentals
Step-by-step explanation:
Latest Releases Depot
rent = $3 per DVD
membership= free
let the number of DVD be x
let the expression for the total be
y= 3x----------------1
Video for You
rent= $2 per DVD
membership= $15
let the number of DVD be x
let the expression for the total be
y= 15+2x----------------2
equate 1 and 2
3x=15+2x
collect like terms
3x-2x=15
x= 15
Hence the number of DVDs needed for the two rentals to have the same amount is at least 15 rentals

Gasoline is pumped at rate of 3 gallons per minute into a container that already has 4 gallons inside
Answer:
1 1/3 minutes
Step-by-step explanation:
Gasoline is pumped at rate of 3 gallons per minute into a container that already has 4 gallons inside
From the above question, we are to calculate the time at which the gasoline is pumped into the container
Hence:
Time = Number of gallons/Rate
Number of gallons = 4
Rate = 3 gallons per minutes
Hence:
Time = 4 gallons/3 gallon per minutes
Time = 1 1/3 minutes
The time at which the gasoline is pumped into the container is 1 1/3 minutes

. An amusement park bought some arcade games that cost $2,000 each and photo booths that cost $3,200 each. A total of 22 of both types of machines were bought, for $53,600. How many arcade game machines did the park buy ?
Answer:
14 arcade games and 8 photobooths were purchased
Step-by-step explanation:
x will represent the number of arcade games
y will represent the number of photobooths
We know that 22 total machines were bought which means that x+y=22
We also know that the total was 53600 which means that 2000x+3200y=53600
We can use substitution to solve this
x+y=22
x-22= -y
-x+22=y
Then plug this in for y in the next equation
2000x+3200(-x+22)=53600
Solve this and get x=14
Then plug in x=14 into any equation (I will choose the x+y one because that's easiest to solve)
14+y=22
this means y=8
This means that 14 arcade games and 8 photobooths were purchased

Which equation best represents the relationship
between x and y in the graph?
A. y = x + 2
C. y = 2x + 2
B. y = 2x - 2
D. y = Vzx - 2
Answer:
C y= 2x +2
Step-by-step explanation:
Look at the graph and look at the dots. For example if you look at negative 1 on the x-axis there is a dot there. so it now you count up to where you see the next dot on the y-axis. Which it goes up 2, then count to the right towards the Y-Axis which is one. now you left with 2/1. since it is going up 2 it will be positive and 2 over 1 is simplified so you are left with 2x and the B will be 2 because the line goes through 2 on the y-axis. This equation should help you y=mx+b m is the slope and B is the y axis

Answer: 0.56
Step-by-step explanation:
Given: Probability that Avacia tree grow small = 0.2
⇒Probability that Avacia tree grow large = 1-0.2=0.8 [Total probability =1]
Probability that Birch tree grow small = 0.4
⇒ Probability that Birch tree grow large= 1-0.4 = 0.6
The probability that both trees will grow to the same size = P(Both large)+P(Both small)
= 0.2 x 0.4 + 0.8 x 0.6 [Events are independent]
= 0.08+0.48
=0.56
Hence, the probability that both trees will grow to the same size = 0.56

Answer:
The area of a triangle is: A = 23.2 cm²
Step-by-step explanation:
Given
a = 10 cm
b = 9 cm
The angle ∠C = 31°
To determine
Area of the triangle
Using the formula to determine the area of the triangle
Area = 1/2bc sin C
substituting a = 10, b = 9, and m∠C = 31°
Area = 1/2 × 9 × 10 × sin 31°
Area = 1/2(90) sin 31°
Area = 45 × sin 31°
Area = 23.2 cm²
Therefore, the area of a triangle is: A = 23.2 cm²
The rope that can fence out the square garden of length 250m can fence another circular garden twice. What is the area and perimeter of the circular garden?
(Wrong answers will be reported)
Answer:
Perimeter of circular garden=500m
Area=19,894 sq m
Step-by-step explanation:
250x4=1000
1000/2=500m circle perimeter
Pi x Dia=Circumference
3.14159 x Dia=500m
Dia=159.16m
Rad=159.16/2=79.58m
Area=Pi x Rad^2=2.14159 x 79.58^2=19,894 m^2
Answer: The circumference of the circular garden is 500 meters.
The area is approximately 19891 square meters.
If you use a Rounded value of 80m for the radius, the Area works out to about 20106 square meters.
Step-by-step explanation:
The total length of the rope is 1000m. 4×250=1000
That is enough to fence the circular garden twice, so the "perimeter" of that garden-- the circumference-- is 500m
To find the area, first find the diameter:
500÷π = 159.15
Area of a circle is A=πr²
The radius is half the diameter.
79.57 so r² is about 6331.4
Multiply by π to get the area:
about 19890.6 m²
Information For The Question:
Maya makes trail mix by combining 1\4 cup of mixed nuts, 1\3 cup of dried fruit, and 1\6 cup of chocolate morsels.
Question:
What is the total amount of ingredients in her trail mix using 12 as the Denominator?
Answer:
3/4
Step-by-step explanation:
1/3 + 1/4 + 1/6=3/4 of a cup-total amount of ingredients in her trail mix.
Simplify the following:
1/3+1/4+1/6
Put 1/3+1/4+1/6 over the common denominator 12. 1/3+1/4+1/6 = 4/12+3/12+2/12:
4/12+3/12+2/12
4/12+3/12+2/12 = (4+3+2)/12:
(4+3+2)/12
4+3+2 = 9:
9/12
The gcd of 9 and 12 is 3, so 9/12 = (3×3)/(3×4) = 3/3×3/4 = 3/4:

At the start of the napkin aisle, you see
a list of the different package options,
shown in the table below.
Are the price of napkins and the
number of napkins in each package
proportional to each other? Why or
why not?
Answer:
D
Step-by-step explanation:
Proportional mean the same but 100 napkins is cheaper then 50 so it is not proportional
Answer:
The answer is D.
No, the ration found by dividing the price of napkins by the number of napkins is not the same for each pack.
Step-by-step explanation:
The prices and the number of napkins in each package are not proportional to each other because they all not equal to each other when the number of napkins is divided by the price
