A movie theater charges $11 for each adult and $6 for each ticket. one day, they sold 163 tickets and made $1578. How many of each ticket did they sell?
Answers
The movie theater sold 117 adult tickets and 46 child tickets.
Explanation:To solve this problem, we can set up a system of equations. Let's say the number of adult tickets sold is x and the number of child tickets sold is y. We can then write two equations based on the given information:
x + y = 163 (equation 1, representing the total number of tickets sold)11x + 6y = 1578 (equation 2, representing the total amount earned)We can solve this system of equations by either substitution or elimination. Let's use elimination:
Multiply equation 1 by 6 to make the coefficients of y in both equations equal:6x + 6y = 978
Subtract equation 1 from equation 2 to eliminate y:(6x + 6y) - (11x + 6y) = 978 - 163
-5x = -585
Divide by -5:
x = 117
Substitute x back into equation 1 to find y:117 + y = 163
y = 163 - 117
y = 46
Therefore, 117 adult tickets and 46 child tickets were sold.

If martha earns $3.25 per hour for baby-sitting, how much will she earn in: 2.5 hours? 4.0 hours? 5.5 hours?
Answers
In 4.0 hours: $3.25 * (4) = $13.00
In 5.5 hours: $3.25 * (5.5) = $ 17.875 → Round to: $17.88 .
____________________________________________
Answer: Martha will earns for 2.5 hours of baby sitting [tex]\approx\$8.13[/tex]
She will earns for 4.0 hours of baby sitting =[tex]\$13[/tex]
She will earns for 5.5 hours of baby sitting =[tex]\approx\$17.88[/tex]
Step-by-step explanation:
Given: Martha earns for each hour of baby sitting = $3.25
Then, Martha will earns for 2.5 hours of baby sitting =[tex]2.5\times3.25=\$8.125\approx\$8.13[/tex]
She will earns for 4.0 hours of baby sitting =[tex]4.0\times3.25=\$13[/tex]
She will earns for 5.5 hours of baby sitting =[tex]5.5\times3.25=\$17.875\approx\$17.88[/tex]

The total cost in dollars to produce q units of a product is C(q). Fixed costs are $13000 . The marginal cost is C'(q)=0.006q^2-q+50.
Estimate C(170) , the total cost to produce 170 units.Find the value of C'(170). Then combine these to find C(171).
Answers
C(170) = 0.002(170)^3 - 1/2(170)^2 + 50(170) + 13000 = 9826 - 14450 + 8500 + 13000 = $16,876
C'(170) = 0.006(170)^2 - 170 + 50 = 173.4 - 120 = $53.40
Therefore, C(171) = C(170) + C'(170) = $16,876 + $53.40 = $16929.40
To find the cost of production for 170 units, consider both fixed costs and variable costs (the integral of the marginal cost function). The cost of producing 171 units can be estimated by adding the marginal cost for the additional unit.
Explanation:The quantity of interest is C(170), the total cost to produce 170 units. To estimate this value, you can calculate the fixed costs plus the integral of the marginal cost from 1 to 170 (the number of items produced).
So, first, calculate the fixed costs which is given as $13000.
Next, estimate the total variable costs, which is the integral of the marginal cost function over the range from 1 to 170 units. Given marginal cost function is C'(q) = 0.006q^2-q+50. Use the power rule to integrate the function, then evaluate it at q=1 and q=170 and subtract.
The value of C'(170) is simply the value of the marginal cost function at q=170.
After finding the value of C(170) and C'(170), the total cost to produce 171 units, C(171), is approximately the total cost to produce 170 units plus the marginal cost to produce the 171st unit.

Renna pushed the button for the elevator to go up, but it would not move. The weight limit for the elevator is 450 kilograms, but the current group of passengers weighs a total of 750 kilograms. Renna wants to determine how many 70-kilogram passengers need to get off the elevator.
Let p represent the number of excess passengers. Write an inequality to determine the number of passengers who need to get off the elevator to meet the weight requirement.
Answers
Passengers weight: 750 kg
Excess weight: 300 kg
Number of 70 kg - passengers: p
Inequality:
70p ≥ 300 kg
Solution of the inequality:
p ≥ 300/70
p ≥ 4.3
Given that p is integer, p ≥ 5
Of course, p must also be less than the initial number of passengers.

Answer:
Range : 0° < x < 17°
Step-by-step explanation:
In any triangle, the smallest angle is opposite to the smallest side.
So, In ΔABD , the side which faces ∠ABD is AD whose length is 22 units.....(1)
And, in ΔCBD, the side which faces ∠CBD is CD whose length is 30 units....(2)
Now, from equations (1) and (2) We get,
∠ABD < ∠CBD
So, ∠ABD lies between 0° to 34°
[tex]\Rightarrow 0 < 2\cdot x<34\\\Rightarrow 0<x<\frac{34}{2}\\\Rightarrow0<x<17[/tex]

What is the leg length of an isosceles right triangle with a hypotenuse of 32 inches?
Answers
that means that those are the legs
a^2+b^2=c^2
a and b are legs and c is the hypotonuse
a=b
2a^2=c^2
c=32
2a^2=32^2
2a^2=1024
divide both sides by 2
a^2=512
sqrt both sides
a=16√2
the legnth of each leg is 16√2 or aprox 22.63 inches
