#27 Using Pythagorean theorem, the length of side ZY is given by
(ZY)^2 = (x - 1)^2 + (x + 1)^2 = (x^2 -2x + 1) + (x^2 + 2x + 1)
= 2x^2 + 2
Taking the square root,
[tex]zy = \sqrt{2 {x}^{2} + 2} [/tex]
#28 There are two shapes that make up this figure: a square of side x and a rectangle with sides (x + 6) and (2x - 3 - x) or (x - 3). Therefore, the area of this figure is
A = area of square + area of rectangle
= (x^2) + (x + 6)(x - 3)
= x^2 + (x^2 + 3x - 18)
= 2x^2 + 3x - 18

The stadium vending company finds that sales of hot dogs average 35,000 hot dogs per game when the hot dogs sell for $2.50 each. For each 25 cent increase in the price, the sales per game drop by 2000 hot dogs. Determine a function R x that models the total revenue per game, where x is the number of $0.25 increases in the price of a hot dog.
Answers
Answer:
A function R x that models the total revenue per game is as follows:
Rx = 87,5000 + 3,750x – 500x^2.
Step-by-step explanation:
Based on the information in the question, we have:
Rx = Total revenue per game
x = Number of $0.25 increases in the price of a hot dog
Average sales of hot dogs = 35,000
Effect of each 25 cent increase in the price on average sales = 35,000 - 2000x
Effect of each 25 cent increase in the price on selling price = 2.5 + 0.25x
Therefore, we have:
Rx = (35,000 - 2000x)(2.5 + 0.25x)
This can be solved further by opening the brackets as follows:
Rx = 87,5000 + 8,750x - 5,000x - 500x^2
Rx = 87,5000 + 3,750x – 500x^2
Therefore, a function R x that models the total revenue per game is Rx = 87,5000 + 3,750x – 500x^2.

The requried simplified value of x in the intersection of two lines is 6.
What are opposite angles?Opposite angles are a pair of angles that are formed when two lines intersect. The two angles are located on opposite sides of the point where the two lines intersect.
Opposite angles are also called vertical angles, and they have equal measures. This means that if we know the measure of one opposite angle, we can find the measure of the other opposite angle by setting them equal to each other.
Here,
When two lines intersect, opposite angles are equal. So, we can set the two opposite angles equal to each other and solve for x.
Given that the opposite angles are 3x + 2 and 20 degrees, we have:
3x + 2 = 20
Subtracting 2 from both sides, we get:
3x = 18
Dividing both sides by 3, we get:
x = 6
Therefore, the value of x is 6.

A trapezoid has an area of 60 square inches. The height of the trapezoid is 5 inches. What is the length of the longer base if the longer base is three times the length of the shorter base?
Answers
Answer:
Step-by-step explanation:
Remark
Let the shorter base = x
Let the longer base = 3x
h = 5
Area = 60
Formula
Area = (b1 + b2)*h /2
Solution
60 = (x + 3x)*5 / 2 Multiply both sides by 2
2*60 = (x + 3x)*5 Combine like terms
120 = 4x *5
120 = 20x Divide by 20
120/20 = x
x = 6
Therefore the two bases are
x = 6
3x = 18

Find the average rate of change of rainfall between years 3 and 6. You must explain and show all of your work.

Answer:
[tex] \displaystyle 702[/tex]
Step-by-step explanation:
we are given a exponential function
[tex] \displaystyle f(x) = {3}^{x + 1} - 22[/tex]
where x represents the number and f(x) represents the amount
we are also given that when x is 3 then f(x) is 59 likewise when x is 6 then f(x) is 2165
to figure out the average rate of change between 3 and 6 we can consider the average rate of change formula given by
[tex] \displaystyle m = \frac{ f(x)_ {2} - f(x)_{1} }{ x_{2} - x_{1} } [/tex]
substitute what we have:
[tex] \displaystyle m = \frac{ 2165 - 59 }{6 - 3 } [/tex]
simplify substitution:
[tex] \displaystyle m = \frac{2106 }{3 } [/tex]
simplify division:
[tex] \displaystyle m = 702[/tex]
hence, the average rate of change between 3 and 6 is 702

A used car dealer sells SUVs and cars. Of all the vehicles, 60% are cars. Of all the vehicles, 15% are red cars. What is the probability that a car chosen at random is not red?
Answers
Answer:
The probability that a car chosen at random is not red is 75%.
Step-by-step explanation:
Given that a used car dealer sells SUVs and cars, and of all the vehicles, 60% are cars, and of all the vehicles, 15% are red cars, to determine what is the probability that a car chosen at random is not red you must perform the following calculation:
60 = 100
15 = X
15 x 100/60 = X
25 = X
100 - 25 = 75
Therefore, the probability that a car chosen at random is not red is 75%.

Answer:
(5,3)
Step-by-step explanation:
add the equations to eliminate to x's and get 8y=24
divide both sides by 8 to get y=3
then substitute in -2x+3(3)=-1 to solve for x
so x=5 so the solution is (5,3)
Answer:
[tex]x=5 \\y=3[/tex]
Step-by-step explanation:
[tex]-2x+3y=-1\\2x+5y=25[/tex]
Add these equations to eliminate x:
[tex]8y=24[/tex]
Then, solve [tex]8y=24[/tex] for y:
[tex]8y=24[/tex]
[tex]\frac{8y}{8} =\frac{24}{8}[/tex] (divide both sides by 8)
[tex]y=3[/tex]
Now let's find the value of x:
Substitute 3 for y in [tex]-2x+3y=-1[/tex]
[tex]-2x+(3)(3)=-1[/tex]
[tex]-2x+9=-1[/tex] (simplify both sides of the equation)
[tex]-2x+9+-9=-1+-9[/tex] (add both sides by -9)
[tex]-2x=-10[/tex]
[tex]\frac{-2x}{-2} =\frac{-10}{-2}[/tex] (divide both sides by -2)
[tex]x=5[/tex]
Therefore, the value of x = 5 and y = 3
A baseball player has a batting average of 0.250, which means he gets a hit 25% of the time he is at bat. If he bats 450 times during the season, how many hits should he expect to get
Answers
Answer:
112.5
Step-by-step explanation:
He should expect 112.5 hits if he bats 450 times during the season.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
A baseball player's batting average is 0.250, which implies he hits 25% of the time he bats.
Here,
batting average = 0.250
number of times batting = 450
According to the given situation, the required solution would be as follows:
The number of hits = batting average × number of times batting
The number of hits = 0.250 × 450
Apply the multiplication operation, and we get
The number of hits = 112.5
Therefore, he should expect 112.5 hits to get.
