1.) You are the crew chief of the Algebra 2 formula racing team. Your current task is to
determine fuel consumption of both cars. Car A travel x² + 3x miles and Car B travels 2x + 8 miles. Based upon tire wear (x), the cars will use x² + 4x gallons of fuel.
a.) What is the mileage

Car A:
Car B:
b.) What is the total mileage for both cars in simplified form? (3 points)

The mileage of Car A, Car B, and the average of is (x+3)/(x+4), 2/x and [tex]\frac{x^{2} +5x +8 }{x^{2} +4x}[/tex]
It is given that the distance traveled by the car A = x² + 3x
And the distance traveled by car B = 2x + 8
The mileage is given by mile/gallon.
So, the mileage of Car A = distance traveled by car A/gallons of fuel used.
Then,
Mileage of Car A = [tex]\frac{x^{2} +3x }{x^{2} +4x} =\frac{x(x +3)}{x(x+4)} = \frac{x+3}{x+4}[/tex] miles /gallons
Similarly, the mileage of Car B = distance traveled by car B/gallons of fuel used.
Then,
Mileage of Car B = [tex]\frac{2x+8}{x^{2} +4x} = \frac{2(x+4)}{x(x+4)} =\frac{2}{x}[/tex] miles/gallons
Now, the total mileage of A and B is the average of car A and car B,
Mileage of Car A + Mileage of Car B = [tex]\frac{x^{2} +3x }{x^{2} +4x} + \frac{2x+8}{x^{2} +4x} = \frac{x^{2} +5x +8 }{x^{2} +4x}[/tex]

What percentage of 3436 is 20
Let x percent of 3436 be 20.
Recall, percentage is expressed in terms of 100. This means that
x/100 * 3436 = 20
34.36x = 20
Dividing both sides of the equation by 34.36, we have
34.36x/34.36 = 20/34.36
x = 0.582%
Thus, 0.582% of 3436 is 20
Jupiter's orbital speed is approximately 52 kilometers in 4 seconds. At this rate, how many kilometers will Jupiter travel in 5 seconds?
Jupiter's orbital speed is approximately 52 kilometers in 4 seconds.
In 4 seconds, she travel = 52km
i.e. in 1 minute she travel = 52/4
In one minutes she travel = 13 km
Distance travel in 5 seconds =
5 x 13 km = 65 km
At this rate Jupitar will travel 65 km in 5 seconds
Answer : Jupitar will travel 65 km in 5 seconds
Graph the equationy = 6
Since the equation has only the variable y and it is a constant value, that means this equation is represented by a horizontal line (the line contains all values of x and always the value of y is 6).
In order to graph this equation, we can graph two points that are on the line (for example, (0, 6) and (1, 6)) and then draw the line that passes through both of them.
So we have:

a. If Links printing store will make a 150 copies for the cost of $15.00, then what is theunit rate of price per copy?
ANSWER
$0.10
EXPLANATION
We have that 150 copies are made for a total cost of $15.00
The unit rate of price per copy is the price of each copy of the printing.
To find the unit rate of price per copy, we have to divide the total price by the total number of copies.
So, we have:
[tex]\frac{15}{150}\text{ = \$0.10}[/tex]This means that the unit rate of price per copy is $0.10
Hello! I need help with this questionTriangle DOG was rotated to create triangle D'O'G''. Describe the transformation using details and degrees.
Answer:
180 degrees rotation about the origin
Explanation:
First, we need to identify the coordinates of DOG and D'O'G' as follows
D(-2, 1) ---> D'(2, -1)
O(-3, 3) ---> O'(3, -3)
G(1, 1) ---> G'(-1, -1)
Therefore, the rule for the transformation is
(x, y) ---> (-x, -y)
This rule is the rule for a 180 degrees rotation about the origin. So, the transformation is a 180 degrees rotation about the origin.
In the quadrilateral below. “Angle WXZ is congruent to Angle YZX." If Ricardo's conjecture is true, which of the following must be true for Quadrilateral WXYZ to be a parallelogram?
Answer:
∠YXZ ≅ ∠WZX
Explanation:
Given that “Angle WXZ is congruent to Angle YZX."
The angles are shown in the diagram below.
This means that angles WXZ and YZX are alternate angles and thus,
• WX is parallel to ZY.
Consider the diagram below:
Angles YXZ and WZX are congruent by alternate angles, and thus:
• WZ is parallel to XY.
So, we have shown that the opposite sides of the quadrilateral are parallel.
Therefore, in order for quadrilateral WXYZ to be a parallelogram, Angles YXZ and WZX must be congruent.
The first option (∠YXZ ≅ ∠WZX ) is correct.
The main printer in the Ivy Tech library can produce an average of 639copies every hour. For every 36 pages, it costs the college $0.06 forelectricity and supplies. If the library is open from 9AM to 9PM, howmuch money does the college use on printing each day?

if a pound of almonds cost eight dollars how many ounces can be bought for $3.80
Proportions
A pound of almonds is said to cost 8 dollars.
But one pound is equivalent to 16 ounces, therefore:
16 ounces cost 8 dollars
Dividing by 8 we get that
2 ounces of almonds cost 1 dollar
Thus, for $3.80 we can buy 2*3.80 = 7.60 ounces of almonds

The equation of the parabola in the vertex form with vertex (6,-6) and passing through (8,6) is y = 3(x - 6)² - 6 , the correct option is (b) .
In the question ,
it is given that ,
the parabola passes through the point (8,6) .
the vertex of the parabola = (6,-6) .
We know that the equation of parabola in the vertex form with vertex (h,k) is
(y - k) = C.(x - h)²
we substitute the vertex and the point passing ,
we get ,
6 - (-6) = C.(8 - 6)²
6 + 6 = C(2)²
12 = 4C
C = 12/4
C = 3
So , the equation is (y - (-6)) = 3.(x - 6)²
y + 6 = 3(x - 6)²
y = 3(x - 6)² - 6
Therefore , The equation of the parabola in the vertex form with vertex (6,-6) and passing through (8,6) is y = 3(x - 6)² - 6 , the correct option is (b) .

What does congruence of triangle mean?Triangles are said to be congruent if the three angles and three sides of a triangle are equal to the corresponding angles and sides of another triangle.
To be congruent, two triangles must have the same size and shape. The two triangles under consideration must overlap. If you rotate, flip, and/or move the triangle, its position and appearance will look different. In this case, we need to identify the six parts of one triangle and the corresponding parts of the other triangle.
For the triangles ΔAXD and ΔCXD
AD = DC ( congruent sides)
∠XDA = ∠XDC = 90° ( XD is perpendicular to AC)
XD is the common side.
This proves that triangles ΔAXD and ΔCXD are congruent
So it concludes, that XD = XC
