You sold a total of 56 student and adult tickets for a total of $328. Student tickets cost $5 and adult tickets cost $8. How many student tickets were sold?
Answer:
The number of student ticket sold is 40
Step-by-step explanation:
Given;
total number of tickets sold,= 56 tickets
total amount the tickets were sold, = $328.
cost of student tickets, = $5
cost of adult ticket, = $8
Let the number of student ticket sold = x
Let the number of adult ticket sold = y
To determine the number of student tickets sold, we will have the following equations;
x + y = 56 ------ equation (1)
5x + 8y = 328 -----equation (2)
from equation (1), y = 56 - x
Substitute the value of y in equation (2);
5x + 8y = 328
5x + 8(56 - x) = 328
5x + 448 - 8x = 328
5x - 8x = 328 - 448
- 3x = - 120
x = 120 / 3
x = 40
Therefore, the number of student ticket sold is 40

Answer:
C. y = -x
Step-by-step explanation:
the slope is -1 so in the formula y= mx + b
b is 0 and m is -1
so plug it in and you get y = -x
The value of y varies directly with x. When y= 75,x= 1.5 What is the value of y when x is 2.25
Answer:answer y = 337.5
Step-by-step explanation:
y varies directly with x, so y = kx , where k is some constant.
y = kx When y = 75 , x = 1/2 . So
75 = k(1/2) Multiply both sides by 2 .
150 = k
y = 150x
To find y when x = 2 , plug in 2 for x .
y = 150( 2 ) 1/4 = 0.25 , so 2 + 1/4 = 2.25
y = 150( 2.25 )
y = 337.5

What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?
Answer:
15.75 milesStep-by-step explanation:
Step one:
given
time= 2.5 hours
speed= 6.3mph
Step two:
Required
Distance
we are given the speed in miles per hour, hence the distance will be in miles
we also know that the expression relating speed, distance and time is given as
speed= distance/time
thus
distance= speed*time
distance= 6.3*2.5
distance= 15.75 miles
By using expression for the speed, distance traveled by me in 2.5 hours will be
Given in the question,
Speed = 6.3 mphTime for travelling = 2.4 hoursExpression for the speed of an object is given by,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Therefore, Distance = Speed × Time
By substituting the values of speed and the time in the expression,
Distance traveled = 6.3 × 2.5
= 15.75 miles
Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.

Nate tosses a ball up a hill for his dog to chase. The path of the ball is modeled by the function y = –14x2 + 335x, where x is the ball’s horizontal distance from Nate in feet and y is the ball’s height in feet. The hill is modeled by the line y = 15x. How far does the ball travel horizontally before it hits the ground?
Answer:
The horizontal distance the ball travels before it hits the ground is 22.[tex]\overline{857142}[/tex] feet
Step-by-step explanation:
The given parameter are;
The function modelling the path of the ball tossed by Nate y = -14·x² + 335·x
x = The horizontal distance the ball travels from Nate in feet
y = The height of the ball in feet
The line equation modelling the hill is y = 15·x
The point where the ball hits the ground is given by the point the graph of the equation for the path of the ball and the path of the model of the line of the hill meet as follows;
Ball path is y = -14·x² + 335·x
Hill path is y = 15·x
The point both paths meet and the ball hits the ground is -14·x² + 335·x = 15·x
Which gives;
-14·x² + 335·x - 15·x = 0
-14·x² + 320·x = 0
320·x - 14·x² = 0
x × (320 - 14·x) = 0
x = 0, or x = 320/14 = 22 6/7 = 22.[tex]\overline{857142}[/tex] feet
Therefore;
The horizontal distance the ball travels before it hits the ground = x = 22.[tex]\overline{857142}[/tex] feet.
The path of ball will be parabolic in nature .Parabolic path is defined as the angle of trajectory of a projectile.
Ball travel 22.86 feet horizontally before it hits the ground.
Since, The path of the ball is modeled by the function [tex]y = -14x^{2} + 335x[/tex]
where x is the ball’s horizontal distance from Nate in feet and y is the ball’s height in feet.
And hill is modeled by equation, [tex]y=15x[/tex]
To find out how much ball will travel horizontally before it hits ground , we have to find intersection of given two model equation.
[tex]y = -14x^{2} + 335x[/tex]
[tex]y=15x[/tex]
So, [tex]-14x^{2} + 335x=15x\\\\-14x^{2} + 335x - 15x = 0\\\\320x - 14x^{2} = 0\\\\x(320-14x)=0\\\\x=0, x=320/14=22.86[/tex]
Thus, Ball travel 22.86 feet horizontally before it hits the ground.

Pierre inherited S269,100 from his uncle and decided to invest the money. He put part of the
money in a money market account that earns 3.1% simple interest. The remaining money was
invested in a stock that returned 4% in the first year and a mutual fund that lost 2% in the first
year. He invested $10,000 more in the stock than in the mutual fund, and his net gain for 1 yr
was $3180. Determine the amount invested in each account.
Answer:
Pierre invested:
$9,000 in money market account$135,050 in stocks$125,050 in the mutual fundStep-by-step explanation:
A = money market account
B = stocks
C = mutual fund
A + B + C = 269,100
0.031A + 0.04B - 0.02C = 3,180
B = 10,000 + C (we will first replace B)
A + 10,000 + C + C = 269,100
A + 2C = 259,100
0.031A + 0.04(10,000 + C) - 0.02C = 3,180
0.031A + 400 + 0.04C - 0.02C = 3,180
0.031A + 0.02C = 2,780
A + 2C = 259,100
-100(0.031A + 0.02C) = -100 · 2,780
A + 2C = 259,100
-3.1A - 2C = -278,000
-2.1A = -18,900
A = -18,900 / -2.1 = $9,000
C = (259,100 - 9,000) / 2 = $125,050
B = $125,050 + $10,000 = $135,050

Using the graph, determine the coordinates of the roots of the parabola.
The roots are located at (2,0) and (4,0)
In short, the roots are x = 2 and x = 4
The term "x intercept" is another way of saying "root". Both describe the location where the graph crosses the x axis.
Answer:
(2,0) and (4,0)
Step-by-step explanation:
Hello!
The roots of the parabola are the coordinates where the graph intersects the x-axis (y = 0).
As you can see, the vertex of the graph is above the x-axis, and opens down, meaning that there are two roots for the graph.
Points of intersection:
(2,0)(4,0)Therefore, the coordinates of the roots are (2,0) and (4,0).

Triangle ABC is an oblique triangle. If angle A equals 57°, angle B equals 73°, and AB equals 24 in, what is the length of side AC?
a.) 30 in
b.) 32 in
c.) 34 in
d.) 36 in
Answer:
Answer is A hope it helps
Step-by-step explanation:
I meant A by my mistake Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
The length of side AC will be 30 inches. Then the correct option is A.
What is law of sines?Let the triangle ABC, with side measures |BC| = a. |AC| = b. |AB| = c.
Then by the sine law, we have
[tex]\rm \dfrac{\sin\angle A}{a} = \dfrac{\sin\angle B}{b} = \dfrac{\sin\angle C}{c}[/tex]
Then angle ∠C will be
We know the sum of angle of the triangle is 180°.
∠C + 57° + 73° = 180°
∠C = 180° – 130°
∠C = 50°
Then the length of side AC will be
sin B / AC = sin C / AB
sin 73° / AC = sin 50° / 24
AC = 29.96 ≈ 30 inches
Then the correct option is A.
