HELP.....to support the high school the local business will donate five dollars for every ticket sold at the homecoming game. If 121 students, 158 home, and 47 visitors tickets were sold, how much money did they donate?
Answer:
2130 but see the note below
Step-by-step explanation:
Remark
It does not matter whether the home team or the visiting team got the support. All that matters is the total number of tickets. Just eye balling it looks like about 1500 dollars.
Equation
Total Donation = 5 * (121 students + 158 + 47)
Solution
Total Donation = 5(426)
Total Donation = 2130
Note:
There is a problem with with. 121 students cannot be included in the 158 or in the 47. If they are, there is no way to be sure what the answer is. I have solved it as though there were 3 separate categories. If that isn't so, you will get it wrong.
Write an equation of the circle with center (-2, 6) and radius 7.
Answer:
( x + 2 )² + ( y - 6 )² = 49
Step-by-step explanation:
→ Write the form of an equation of a circle
( x - a )² + ( y - b )² = r²
→ Substitute in the centre remembering to switch the signs
( x + 2 )² + ( y - 6 )² = r²
→ Substitute in radius
( x + 2 )² + ( y - 6 )² = 49

The table of values shows the height of a buoy compared to the sea floor over time as the tide goes in and out. This can be modeled by a sinusoidal function.
Which statements are true?
Select EACH correct answer
The maximum value of the function is 5.8
The amplitude of the function is 5.8
The period of the function is 24
The frequency of the function is 24
Answer:
1st statement is true
2nd is false (amplitude is (max - min) ÷ 2 so (5.8 - 4.6) ÷ 2 = 0.6)
3rd is true
4th is false (frequency is the reciprocal of period, they can't be the same)

A family had 1/3 of pizza left over. Later 3 people shared the remaining 1/3 equally. What fractional part of the whole pizza did each get
Answer: 1/9 pizza portions
Step-by-step explanation:
The pizza was left with only 1/3 of it and 3 people shared this.
The fractional part of the whole pizza that each of the three people ate is therefore:
= Percentage of who pizza left / Number of people
= 1/3 ÷ 3
= 1/3 * 1/3
= 1/9 pizza portions

Steve earned $7.40 per hour working his paper route. The first week, he worked 16 hours. After getting paid, he put $105 in the bank and spent the rest on rides at the carnival. Each ride cost $0.75. How many rides did Steve ride at the carnival?
Answer:17
Step-by-step explanation: Multiply Steve’s hourly wage ($7.40) by the hours he worked in a week (16 Hours) that would give you your weekly earnings which would be (7.40x16=$118.40) Then subtract what he saved in the bank from your total (118.40-105=$13.40) then you would divide $13.40 (his leftover money) by $0.75 to find the total number of carnival rides he could ride (13.40/0.75=17.86 rides and because he cannot ride 17 and 86 hundredths of a ride he would be able to ride 17 carnival rides.
A parabola has its minimum point at (3,-5) and the y coordinate of the y-intercept is -2.
What is the equation of the parabola?
Answer:
y = [tex]\frac{1}{3}[/tex] x² - 2x - 2
Step-by-step explanation:
x-coordinate of the vertex of a parabola is ( [tex]- \frac{b}{2a}[/tex] )
y = f(x) = ax² + bx + c
(x, y) ∈ f(x)
~~~~~~~~~
{ (0, - 2), (3, - 5) } ⊂ { (x, y): y = ax² + bx + c }
a(0)² + b(0) + c = - 2 ⇒ c = - 2
a(3)² + b(3) + ( - 2) = - 5
9a + 3b - 2 = - 5 ⇒ 3a + b = - 1
[tex]- \frac{b}{2a}[/tex] = 3 ⇒ b = - 6a
[tex]\left \{ {{3a+b=-1} \atop {b=-6a}} \right.[/tex]
3a + ( - 6a) = - 1
a = [tex]\frac{1}{3}[/tex]
b = - 2
y = [tex]\frac{1}{3}[/tex] x² - 2x - 2
The equation of the parabola for the given values is y = x²/3 - 2x - 2.
What is a parabola?A parabola is the part of the conic section of which the points are equidistant from a fixed line called as directrix and a fixed point known as focus.
The general equation for the parabola is given as,
y = ax² + bx + c
Where c is the y-intercept.
Substitute c = -2 as per the question to obtain,
y = ax² + bx - 2
At (3,-5) the parabola has minimum value which implies y' = 0 as below,
y' = 2ax + b = 0
Substitute x = 3 to obtain,
2a × 3 + b = 0
=> -6a = b
And, y = -5 at x = 3 which gives,
-5 = 3²a + 3b - 2
=> 9a + 3b = -3
Substitute b = -6a to get,
9a - 18a = -3
=> a = 1/3
Which implies b = -6 × 1/3 = -2
Now, the equation for the parabola becomes as below,
y = x²/3 - 2x - 2
Hence, the required equation of the parabola is obtained as y = x²/3 - 2x - 2.

After 5 years, Marcel's account earned $900 in interest. If the interest rate (in decimal form) is 0.06, how much did Marcel initially invest?
Answer:
$3000
Step-by-step explanation:
I= PRT÷100
where,
I = interest = 900
T= 5
R/100 = 0.06
P = ?
I= PRT/100
900= P × 5 × 0.06

Answer:
18.38Explanation:
since this triangle is a right-angled triangle and one its angles equals 45° then it's an isosceles right triangle which means that the side opposite 45° (the side to the left) is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
note: in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!
