At the local art exhibit, childrens tickets cost $3 each and adult tickets cost $4 each. On a certain day, the exhibit sold 56 tickets and earned $203 in revenue. How many childrens tickets and how many adult tickets were sold?

Answers

Answer:

Children=21 Adult=35

Step-by-step explanation:

[using c for children tickets and a for adult tickets]

56=c+a and 203=3c+4a [starting system of equations]

a=56-c ---> 203=3c+4(56-c) [plugging the first eq. into the second]

203=3c+224-4c [simplify]

-21=-c [simplify 2.0]

c=21 [simplify 3.0]

56=21+a [plugging back into org. eq.]

so a=35

A TV has a listed price of $751.98 before tax. If the sales tax rate is 8.75%, find the total cost of the TV with sales tax included.
Round your answer to the nearest cent, as necessary.

Answers

Answer:

$817.78

Step-by-step explanation:

To find the tax you must do the equation:

751.98 x 0.0875

(Btw, 0.0875 is decimal form of 8.75%. Always turn the percentage into a decimal before finding the tax or sale amount)

751.98 x 0.0875 = 65.80.

Now, add the sale tax amount and the original price:

751.98 + 65.80 = 817.78

Therefore, the answer is 817.78.

A train moving at 40km/h applies brakes so that there is a constant 0.5m/s².find the time taken before the train stops.

Answers

Answer:

t = 22.22 s

Step-by-step explanation:

Given that,

The initial speed of the train, u = 40 km/h

Acceleration of the train, a = 0.5 m/s²

Finally, it stops, v = 0

We need to find the time taken by it to stop. using first equation of motion to find it such that,

[tex]v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{0-40\times \dfrac{5}{18}}{-0.5}\\\\t=22.22\ s[/tex]

So, it will take 22.22 seconds to stop.

The total area is 45 square inches.

Area of Compound Shapes

This question requires your knowledge about the area of compound shapes. For solving this, you should:

Identify the basic shapes;Calculate your individual areas; Sum each area found.

STEP 1 - Identify the basic shapes.

The figure is composed of:

two squares whose sides are equal to 3 in. 1 rectangle whose sides are: 9 in and 3 in

Therefore, you should sum the area of these geometric figures for determining the given area.

STEP 2 - Find the area of the squares.

Area of each square = a², where a=the length of the side.

Like, the length of the side is equal to 3 in, the area will be:

A_square= 3²=9 in².

You have two squares in the figure. Then, the total area for the squares is 9 + 9 =18 in²

STEP 3 - Find the area of the rectangle.

Area of the rectangle = bh . The figure shows that: the base = 9 in and the 3=8 in

Thus, A_rectangle=bh= 9*3=27in²

STEP 4 - Find an expression for the total area of the figure.

A_total= A_squares+ A_rectangle

A_total= 18+27=45 in²

A_total= 45in²

A sports marketing company is interested in how many hours teenagers in a town spend watching sports. They randomly select 40 teenagers in this town and ask how many hours per week they spend watching sports. The mean amount is 6.25 hours with a standard deviation of 4.33 hours. Which of the following is the 90% confidence interval for the true mean amount of time teenagers from this town watch sports?

Find the t-table here.

(4.396, 8.104)
(4.865, 7.635)
(5.097, 7.404)
(5.245, 7.256)

Answers

Answer:

(5.097, 7.404)

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 40 - 1 = 39

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 39 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.6849

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.6849\frac{4.33}{\sqrt{40}} = 1.154[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 6.25 - 1.154 = 5.096 hours

The upper end of the interval is the sample mean added to M. So it is 6.25 + 1.154 = 7.404 hours.

The answer is (5.097, 7.404)

First, rewrite
7/9 and 16/21
so that they have a common denominator.
