a total of 360 tickets were sold for the school play. they were either adults tickets or student tickets. the number of student tickets sold was two times the number of adult tickets sold. how many adult tickets were sold?
Answer by chibabykalu1 (Show Source): You can put this solution on YOUR website!
x, =student tickets
y, =adult tickets
-----
=> x + y = 360 --------(1) x = 2y. ----------(2)exact translation of the description into a system of equations. Solve for the value of y.
The process can be, solve for x in terms of y, already seen as THE second equation of the system; substitute into the other equation, and solve the result for y, and compute.
=> {2y} + y = 360=> 2y + y = 360=> 3y = 360=> (3y)/3 = +360)/4=> y = 120 ----------adult tickets sold.Substitute y = 120 into equation 2
=> x = 2y=> x = 2(120)=> x = 240 (children tickets sold)what is the missing factor in x2−x−42=()(x−7)

A sample contains 16.75 g of the radioisotope u-236 and 50.25 g of its daughter isotope, th-232. how long did it take for decay to take place if one half-life of u-236 is 23 million years? 46 million years 69 million years 92 million years 115 million years
If one half-life of U-236 is 23 million years then it will take 45.5 or approximately 46 million years to decay. Then the correct option is A.
What is half-life?Half-life is the time interval that is needed to decay the atomic nuclei of a radioactive sample.
A sample contains 16.75 g of the radioisotope U-236 and 50.25 g of its daughter isotope, Th-232.
Initially, the whole sample is consisting the radioisotope. Then the initial total mass will be
m₀ = 16.75 + 50.25
m₀ = 67 g
Now we also know that the half-life is 23 million years. Then we have
[tex]m = m_oe^{- \lambda t}[/tex]
Then put the value
[tex]\begin{aligned} 16.75 &= 67 e^{- \lambda t}\\\\0.254 &= e^{- \lambda t}\\\\\lambda t &= 1.37\\\\\dfrac{ln2}{23 \rm \ million \ years } \times t &= 1.37\\\\t &= 45.5 \ \rm million\ years \end{aligned}[/tex]
If one half-life of U-236 is 23 million years then it will take 45.5 or approximately 46 million years to decay. Then the correct option is A.

Answer:
x = 30
Step-by-step explanation:
Supplementary angles sum to 180° , then
2x + 10 + 3x + 20 = 180 , that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30

Help guys asap this is due today. Find the volume of the cylinder. Find the volume of a cylinder with the same radius and double the height.
The volume of the cylinder in^3?
The volume of with the same radius and double the height is ?
Answer:
226.2 in³ and 452.4 in³
Step-by-step explanation:
Volume of original shape:
Volume = base area x height
Volume = πr² x 2
Volume = π(6)² x 2
Volume = 113.10 x 2
Volume = 226.2 in³
Volume with same radius but double the height:
Volume = base area x height
Volume = πr² x 2(2) ----------> multiplied by 2 because height is being doubled
Volume = 113.10 x 4
Volume = 452.4 in³

A candy distributor needs to mix a 40% fat-content chocolate with a 50% fat-content chocolate to create 100 kilograms of a 41% fat-content chocolate. How many kilograms of each kind of chocolate must they use? A) Write an equation that uses the information as it is given above that can be used to solve this problem. Use x as your variable to represent the quantity of 40% fat-content chocolate. Equation: B) Answer: They must mix ?Kilograms of the 40% chocolate and ?Kilograms of the 50% chocolate.
Answer:
The kilograms of chocolate for the 40% fat content (1st chocolate) = 90kg
The kilograms of chocolate for the 50% fat content (2nd chocolate) = 10kg
Step-by-step explanation:
A candy distributor needs to mix a 40% fat-content chocolate with a 50% fat-content chocolate to create 100 kilograms of a 41% fat-content chocolate. How many kilograms of each kind of chocolate must they use?
Let us represent
Kilograms of first chocolate = x
Kilograms of second chocolate = y
A candy distributor needs to mix a 40% fat-content chocolate with a 50% fat-content chocolate to create 100 kilograms of a 41% fat-content chocolate.
Hence:
40% × x + 50% × y = 41% × 100
0.40x + 0.50y = 0.41× 100
0.40x + 0.50y = 41.......Equation 1
x + y = 100kg ......Equation 2
x = 100 - y
Substitute 100 - y for x
0.40(100 - y) + 0.50y = 41
40 - 0.40y + 0.50y = 41
Collect like terms
- 0.40y + 0.50y = 41 - 40
0.10y = 1
y = 1/0.1
y = 10.
Therefore, the kilograms of chocolate for the 50% fat content (2nd chocolate) = 10kg
Remember:
x = 100 - y
x = 100kg - 10kg
x = 90kg
The kilograms of chocolate for the 40% fat content (1st chocolate) = 90kg

Marcy is putting a wallpaper border at the top of the walls of her baby's rectangular room. The width of the room is 2 feet less than the length. If she needs 52 feet of border, what are the dimensions of the room?
Answer:
The baby's rectangular room is 14 feet long and 12 feet wide
Step-by-step explanation:
Assume we set:
x=width of the room
y=length of the room
The width of the room is 2 feet less than the length:
[tex]x=y-2\qquad\qquad [1][/tex]
The total length of the wallpaper needed is the perimeter of the room. The formula for the perimeter of a rectangle is:
P=2x+2y
And the perimeter is equal to 52 feet:
2x+2y=52
Dividing by 2:
[tex]x+y=26\qquad\qquad [2][/tex]
Substituting x from [1]:
y-2+y=26
Simplifying:
2y-2=26
Adding 2:
2y=28
Solving:
y=28/2=14
y=14
Find x:
x=y-2=14-2=12

A server makes $200 a week working at a local restaurant. The server saves 35% of the $200 weekly earnings each week for 4 weeks.
If the server saves 7/8 of the 5th week’s $200 earnings, how much money will the server have saved in total after the 5 weeks?
.$245
.$305
.$315
.$455
The total amount of money the server would have saved after 5 weeks is $455.
What is the total amount saved?The first step is to determine the total amount of money saved for the first four weeks.
Total amount of money saved in the first four weeks = 35% x (200 x 4) = $280
Amount saved on the 5th week = 7/8 x $200 = $175
Total savings = $175 + $280 = $455
