Answer:
15.2
Step-by-step explanation:
1) First, add all of the numbers together. 1+5+7+9+11+16+18+20+30+35=152.
2) Then, divide this by the amount of numbers. There are 10, so it is 152÷10=15.2
3) The answer is 15.2
Write the equation of a parabola in factored form if the x-intercepts are (3,0) and (-5,0) with a maximum point at ( -1,8)
Answer:
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)
Step-by-step explanation:
Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are
(x - 3) and (x + 5)
The equation is the the product of the factors, that is
y = a(x - 3)(x + 5) ← a is a multiplier
To find a substitute (- 1, 8) into the equation
8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )
- [tex]\frac{1}{2}[/tex] = a
Then
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form

Match the following expression 12(x-3)+18=4(3x-3) with the number of solutions below.
A.One solution?
B.No solution ?
Or
C.All solution?
Answer:
No Solution.
Step-by-step explanation:
12(x-3)+18=4(3x-3)
12x-36+18=12x-12
12x-12x-18=-12
-18=-12
no solution

Find the value of each variable
Answer:
a° = 41°
b° = 139°
Step-by-step explanation:
a° = ∠DB
a° = 41°
b° + 41° = 180°
b° = 180° - 41°
b° = 139
At the football game, 3 hamburgers and 6 soft drinks cost $27, and 3 hamburgers and 3 soft drinks cost $18. Which two equations can be used to determine the price of a hamburger and the price of a soft drink?
Let x represent the cost of a hamburger and y represent the cost of a soft drink.
Answer:
Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.
The cost of 4 hamburguers can be represented with this expression:
4x4x
And the cost of 6 soft drinks can be represented with this expression:
6y6y
Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:
4x+6y=344x+6y=34 [Equation 1]
The following expression represents the the cost of 3 soft drinks:
3y3y
According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:
4x+3y=254x+3y=25 [Equation 2]
Therefore, the Equation 1 and the Equation 2 can be used to determine the price of a hamburger and the price of a soft drink
Answer:
3x + 6y = 27
3x + 3y = 18
x = $3, y = $3
Step-by-step explanation:
I will solve by using the elimination method.
3x + 6y = 27
3x + 3y = 18
Subtract top equation by bottom.
3x + 6y = 27
- (3x + 3y = 18)
_____________
0 + 3y = 9
3y = 9
y = 3
Plug y in for three
3x + 6*3 = 27
3x + 18 = 27
3x = 9
x = 3
So, your solution is x = $3, y = $3

Ben's Game World is having a sale on video games. The store is offering a sale pack of 4 video games for $43.80. What is the unit price of a video game in the sale pack?
Answer:
Answer:
a) 10.95
b) 76.65
Step-by-step explanation:
To find the unit price of Ben's video games, divide 43.80 by 4, which is equal to 10.95. So, the unit price is 10.95 at Ben's Game World.
Then, using the unit price we found earlier, multiply 10.95 by 7, which will gives us the cost of 7 games at Roberto's Electronics. You'll get 76.65. So, the cost of 7 games at Roberto's Electronics, using the same unit price at Ben's Game World, would be 76.65.
Hope this helps :)

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes. Each small box can hold 25 books and each large box can hold 50 books. There were 3 more large boxes sent than small boxes, which altogether can hold 450 books. Determine the number of small boxes sent and the number of large boxes sent.
There were ____ small boxes sent and ____ large boxes sent.
Answer:
there were 4 small boxes sent and 7 large boxes sent
Step-by-step explanation:
let s= number of small boxes
let y= number of small boxes
each small box can hold 25 books, so s small boxes can hold 25s books. Each large box can hold 50 books, so l large boxes can hold 50lbooks. Therefore, the total number of books 25s+50l equals 450.
Since there were 3 more large boxes sent than small boxes, if we add 3 to the number of small boxes, we will get the number of large boxes, meaning l equals s+3.
system of equations:
25s+50l=450
l=s+3
substitute values

Barnes and Noble pays a publisher $1.50 for a magazine. The magazine is marked-up 12%. Find the new SELLING PRICE of the magazine.
Answer: The selling price will be $1.68
Step-by-step explanation:
If the magazine is marked-up by 12% , then you will multiply 12% by the amount of money then add it to the same amount of money.
1.50 * 12% = 0.18
1.50 + 0.18 = 1.68
you look down at an object on the ground. If your eyes are
55 feet above the ground, and the angle of depression is 50º, how far is the object
from you?
i believe it’s 2,750 feet?
Answer:
We can think of this as a triangle rectangle.
We know that you eyes are 55ft above the ground, this can be one cathetus.
We also know that you see with an angle of depression of 50°, from this angle, our known cathetus would be the opposite cathetus.
Now we want to know how far is the object from you, this would be the hypotenuse of the triangle rectangle.
So we only know one angle and the opposite cathetus to this angle, then we can use the relation:
Sin(θ) = (opposite cathetus)/(hypotenuse)
Then if we use this equation, we will get:
Sin(50°) = 55ft/hypotenuse
hypotenuse = 55ft/sin(50°) = 71.8 ft
This means that the distance between you and the object is 71.8 ft.
