Kim's school is selling tickets to a play. On the first day of ticket sales the school sold 5 senior citizen tickets and 6 child tickets for a total of $148. The school took in $189 on the second day by selling 7 senior citizen tickets and 7 child tickets. Find the price of a senior citizen ticket andthe price of a child ticket.
Answers
Answer:
Child $13 and Adult $14
Step-by-Step
x=cost of child tix
y=cost of adult tix
first day: 5y+6x=148
2nd day: 7y+7x=189
series of equations so solve for one variable
7y=189-7x
y=27-x
then plug into other equation
5(27-x)+6x=148
135-5x+6x=148
x=148-135
x=13
then plug into y equation
y=27-13
y=14

Mrs. Womack wants to make 22 mini pizzas for her favorite math class party. She
has 18 cups of flour and each mini pizza takes 4 cup of flour. Does she have enough
flour? If not, how much more flour does she need? If so, how much flour will she
have left over?
Answers
Answer:
She can only make 4 whole mini pizzas and needs 70 more cups of flour and will not have any leftover after that.
Step-by-step explanation:
18/4= 4.5
22*4=88
88-18= 70
Answer:
No
Step-by-step explanation:
Mrs. Womack need 22 mini pizzas and each requires 4 cups and when you do the math 22 times 4 is 88, and she only has 18 cups so she would only have enough to make 4 full pizzas. So in total she needs 88 cups meaning she needs 70 more.
22x4=88
88-18=70
18÷4= 4.5
Answer:70 more cups are needed
X-4/2 = 4x-9/3
A x=-6
B x=-3/5
C x=6/5
D x =6/11
Answers
Answer:
x = 6/5
Step-by-step explanation:
x-4 4x-9
------ = ----------
2 3
Using cross products
3 * (x-4) = 2 ( 4x-9)
Distribute
3x-12 = 8x-18
Subtract 3x from each side
3x-12-3x = 8x-18-3x
-12 = 5x-18
Add 18 to each side
-12+18 =5x-18+18
6 = 5x
Divide by 5
6/5 = 5x/5
6/5 =x
how do you find the vertex of a quadratic equation in standard form?
Answers
Answer:
Step-by-step explanation:
The standard form of a quadratic equation is ax² + bx + c, where a ≠ 0.
Given that the axis of symmetry occurs at x = h, then we can assume that the h coordinate of the vertex is the same as the x-coordinate in an ordered pair, (x, y).
In order to find the vertex, (h, k), use the following formula to solve for the value of h:
[tex]h = \frac{-b}{2a}[/tex].
Example:To demonstrate this concept, let's say that we're given the following quadratic equation: 2x² + 8x + 8, where a = 2, b = 8, and c = 8. Substitute the values of a and b into the given equation for solving the x-coordinate (h) of the vertex:
[tex]h = \frac{-b}{2a}[/tex]
[tex]h = \frac{-8}{2(2)} = \frac{-8}{4} = -2[/tex]
Therefore, h = -2.
Next, substitute the value of h = -2 into the given quadratic equation in order to solve for its corresponding y-coordinate (k ) of the vertex:
k = 2x² + 8x + 8
where: a = 2, b = 8, and c = 8
k = 2(-2)² + 8(-2) + 8
k = 2(4) - 16 + 8
k = 8 - 16 + 8
k = 0
Therefore, the vertex of the quadratic equation, 2x² + 8x + 8 is (-2, 0).

Need Help?
Read It
Answers
If x terminates in the fourth quadrant, then we know that sin(x) < 0 and cos(x) > 0. Given that sec(x) = 8, we immediately have
cos(x) = 1/sec(x) = 1/8
Recall the Pythagorean identity,
cos²(x) + sin²(x) = 1
Then it follows that
sin(x) = -√(1 - cos²(x)) = -3√7/8
Now recall the double angle identities,
sin(2x) = 2 sin(x) cos(x)
cos(2x) = cos²(x) - sin²(x)
Then
sin(2x) = 2 (-3√7/8) (1/8) = -6√7/64 = -3√7/32
cos(2x) = (1/8)² - (-3√7/8)² = -62/64 = -31/32
By definition of tangent,
tan(x) = sin(x)/cos(x)
Then
tan(2x) = sin(2x)/cos(2x) = (=3√7/32) / (-31/32) = 3√7/31

Answers
Answer:
36.67%
Step-by-step explanation:
So if 600 kids in total and 10% participate, then we have 60 kids to work with. Panthers plus beavers plus jaguars = 2 + 15 + 21 = 38. 38 + 22 = the total 60 kids. 22 is 36.67% percent of 60 because that's what 22/60 equals.
