Mr. Ramirez purchased 50 concert tickets for a total of $575. The concert tickets cost $15 for adults and $10 for children under the age of 12.
Write and solve a system of equations to represent the given scenario. Use the variables "a" for adults and "c" for children.
Answers
Explanation:
a = adult tickets
c = child tickets
a + c = 50
15a + 10c = 575
The first equation can be rearranged and substituted into the second equation.
a = 50 - c
15(50 - c) + 10c = 575
750 - 15c + 10c = 575
750 - 5c = 575
-5c = -175
c = 35
The value of c can be substituted into either one of the original equations to find a.
a + c = 50
a + 35 = 50
a = 15
Check:
a + c = 50
15 + 35 = 50
50 = 50
15a + 10c = 575
15*15 + 10*35 = 575
225 + 350 = 575
575 = 575

An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?
3.23%
3.33%
37.2%
35.5%
Answers
Answer:3.33%
easy
Step-by-step explanation:
A = true value = 60
B = estimated or measured value = 62
C = percent error
C = ( |A-B|/A ) * 100%
C = ( |60-62|/60 ) * 100%
C = (2/60)*100%
C = 0.0333*100%
C = 3.33%

the cost of plastering the wall of a room which is 4m high and breadth is one third of its length is Rs 640 at the rate of Rs 5/ meter square. What will be the cost of carpeting its floor at rate of rs 250/ meter square.
Answers
Answer:
Step-by-step explanation:
Please refer to the attachement. I defined the height (H), width (W), and length (L) and set:
H = 4m and W = (1/3)L. The total cost of 640 Rs/m^2 is divided by the rate cost of Rs 5/m^2 to give 128 m^2 that was plastered. The total area of the walls must be 128 m^2, so then calculate the total wall area: The walls for the length are 2*LH and for the width are 2*WH. Substituting, we have a total of 8*L + (4/3)L = 128 m^2. Solve for L to obtain L = 12m. W is 1/3L, or 4m. The room is (W,L,H) 4, 12, and 4 meters. The floor is W*L, or 48m^2. At Rs 250/m^2, the rug will cost Rs 12000. Ouch.

A physicist working in a large laboratory has found that light particles traveling in a particle accelerator increase velocity in a manner that can be described by the linear function -4x+y=15, where x is time and y is velocity ion kilometers per hour. Use this function to determine when a certain particle will reach 30 km/hr.
Answers
Answer:
it will take the certain particle 15/4 (unit of time) to reach 30 km/hr
Input 30 as for y and solve the equation.
Step-by-step explanation:
Since y is kilometers per hour and the question is asking for how long it takes for a certain particle to reach 30 km/hr, you input 30 for y and solve for x.
-4x + y = 15
-4x + (30) = 15
subtract 30 from both sides
-4x = -15
divide -4 from both sides
x = 15/4
it will take the certain particle 15/4 (unit of time) to reach 30 km/hr

Answers
Answer:
Both of them are correct.
Step-by-step explanation:
Both of them are correct.
EQ. 1) y = -2x + 3
EQ. 2) 6x + 3y = 9
Transform EQ. 2 into its slope-intercept form, y = mx + b:
6x + 3y = 9
6x - 6x + 3y = -6x + 9
3y = -6x + 9
3y/3 = (-6x + 9)/3
y = -2x + 3 (As you can see, Equation 2 is equivalent to Equation 1's).
Given that Equations 1 and 2 are equivalent, their lines will coincide on top of each other (as if they're the same line) once graphed.
Therefore, the systems of linear equations will have infinitely many solutions.
Let's see why Charles and Destiny are both correct with their claims.
If you plug in Charles' coordinates (3, -3) in both equations,
EQ. 1) y = -2x + 3
-3 = -2(3) + 3
-3 = -6 + 3
-3 = -3 (True statement)
EQ. 2) 6x + 3y = 9
6(3) + 3(-3) = 9
18 - 9 = 9
9 = 9 (True statement)
Do the same thing for Destiny's coordinates: (-1, 5)
EQ. 1) y = -2x + 3
5 = -2(-1) + 3
5 = 2 + 3
5 = 5 (True statement)
EQ. 2) 6x + 3y = 9
6(-1) + 3(5) = 9
-6 + 15 = 9
9 = 9 (True statement)
With these calculations, it shows that both of their coordinates are solutions to the given systems of linear equations.

Given M ,N find the value of x
Answers
Answer:
x = 59 , y = 44
Step-by-step explanation:
(2x + 18) and (x - 15) are adjacent angles on a straight line and sum to 180°
2x + 18 + x - 15 = 180 , collect like terms
3x + 3 = 180 ( subtract 3 from both sides )
3x = 177 ( divide both sides by 3 )
x = 59
Then
x - 15 = 59 - 15 = 44
y and (x - 15) are corresponding angles and are congruent , then
y = 44
Justify each step and simplify the equation.
