Answer:

188 children and 145 adults were admitted in the park.

Step-by-step explanation:

Given:

The admission fee at an amusement park is $1.50 for children and $4 for adults.

Total $862 collected on a certain day when 333 people enter the park.

Now, to find the children and adults admitted in the park.

Let the number of children admitted be [tex]x.[/tex]

And the the number of adults admitted be [tex]y.[/tex]

So, the total people enter the park:

[tex]x+y=333\\\\x=333-y\ \ \ ...(1)[/tex]

Thus, the total amount collected of the admission fee:

[tex]1.50(x)+4(y)=862\\\\[/tex]

Substituting the value of [tex]x[/tex] from equation (1):

[tex]1.50(333-y)+4(y)=862\\\\499.50-1.50y+4y=862\\\\499.50+2.50y=862\\\\Subtracting\ both\ sides\ by\ 499.50\ we\ get:\\\\2.50y=362.50\\\\Dividing\ both\ sides\ by\ 2.50\ we\ get:\\\\y=145.[/tex]

Thus, the number of adults = 145.

Now, to get the number of children by substituting the value of [tex]y[/tex] in equation (1) we get:

[tex]x=333-y\\\\x=333-145\\\\x=188.[/tex]

Hence, the number of children = 188.

Therefore, 188 children and 145 adults were admitted in the park.

The price of the cookbook is $40, and the price of the science fiction novel is $15. This was determined by setting up and solving a system of equations based on the sales data provided for two different days.

The student has asked to determine the price of each book based on the sales data for two days. This is a system of equations problem in which we have two equations with two unknowns, representing the prices of two different books. Let's denote C as the price of the cookbook and S as the price of the science fiction novel. From the information given:

4C + 5S = 235 (sales on the first day).

3C + 4S = 180 (sales on the second day).

By solving these two equations simultaneously, we can find the exact prices for both books.

Step 1: Multiply the second equation by 4/3 to align the coefficient of C with the first equation:

([tex]\frac{4}{3}[/tex])(3C + 4S = 180)

4C + ([tex]\frac{16}{3}[/tex])S = 240

Step 2: Subtract the first equation from this new equation:

[([tex]\frac{16}{3}[/tex])S - 5S] = [240 - 235]

[tex]S = \frac{5 }{ \frac{16}{3} - \frac{15}{3}}[/tex]

[tex]S = \frac{5 }{ \frac{1}{3}}[/tex]

S = $15 (price of the science fiction novel)

Step 3: Substitute the value of S in one of the original equations to find C:

3C + 4(15) = 180

3C + 60 = 180

3C = 120

C = $40 (price of the cookbook)

Step-by-step explanation:

x + y = 6 ...................equation 1

x - y = 10 ..................equation 2

Solving equation 1 and 2

x + y = 6

x - y = 10

2x = 16

x = 16 /2

Therefore x = 8

Now

putting x = 8 in equation 1

8 + y = 6

y = 6 -8

y = -2

hope it was helpful :)

Answer:

x=8 and y= -2

Step-by-step explanation:

x+y=6

x-y=10      +              ( add them together)

-----------------

2x=16                          ( substitute/ plug x back in )

x=8

8+y=6

8-y=10

The measure of angle CBD in a regular pentagon with perimeter 60 cm is 108°. This conclusion assumes that CBD refers to an internal angle of the pentagon and is based on the formula for internal angles of a regular polygon.

The subject of the question is related to a regular pentagon which is a polygon with 5 equal sides and equal angles. If the perimeter of the regular pentagon is 60 cm, it means each side measures 60/5 = 12 cm.

The question is asking for the measure of angle CBD. In a regular pentagon, angles are not directly named but it's likely referring to an internal angle of the pentagon. Based on this assumption, we can calculate the measure of an internal angle of a regular polygon using the formula: (n-2) x 180° / n where 'n' is the number of sides. Substituting '5' in place of 'n' because a pentagon has 5 sides, we get (5-2) x 180° / 5, which results in 108°. Therefore, if CBD is an internal angle then it measures 108 degrees.

Answer: the value us 2.064

Step-by-step explanation:

To determine the t value, we would need the t distribution table. Since degree of freedom is known as 24, we would determine alpha/2

A 95% confidence level is 95/100 = 0.95

1 - alpha = 0.95

alpha = 1 - 0.95

alpha = 0.05

alpha/2 = 0.05/2 = 0.025

this is the area to the left. The area to the right 1 - 0.025 = 0.975

alpha/2 = 0.975

Looking at the t distribution table, the t value is

The surface area of the cereal box is 2600 square centimeters. Volume of the cereal box is 7500 cubic centimeters.

The surface area of the cereal box in the image is 2600 square centimeters. The volume of the cereal box is 7500 cubic centimeters.

To calculate the surface area, we need to find the area of each of the six faces of the box and add them all up. The two largest faces have dimensions 25 cm by 30 cm, so their area is 25 * 30 = 750 square centimeters each. The two next-largest faces have dimensions 10 cm by 30 cm, so their area is 10 * 30 = 300 square centimeters each. The two smallest faces have dimensions 25 cm by 10 cm, so their area is 25 * 10 = 250 square centimeters each. Therefore, the total surface area of the box is 750 + 750 + 300 + 300 + 250 + 250 = 2600 square centimeters.

To calculate the volume, we simply multiply the length, width, and height of the box together. The length is 25 cm, the width is 10 cm, and the height is 30 cm, so the volume is 25 * 10 * 30 = 7500 cubic centimeters.

Here is a table summarizing the surface area and volume of the cereal box:

Step-by-step explanation:

Given:-

- The material cost per square foot, C = $1.25

- The two boxes have the dimensions:

         Box 1 : ( 9 x 9 x 10 ) in

         Box 2: ( 11 x 7 x 10 ) in

Find:-

so how much does a company save by choosing to make 50 of Box 2 instead of Box 1?

Solution:-

- We will first determine the surface areas of the two boxes Box 1 ( A1 ) & Box 2 (A2).

               A1 : 2*( 9*9) + 4*( 9*10) = 522 in^2 = 43.5 ft^2

               A2 : 2*(11*7) + 2*(11*10) + 2*(7*10) = 514 in^2 = 42.833 ft^2

- Determine the cost for each box:

               Cost of box 1 = A1*C = 43.5*$1.25 = $54.375

               Cost of box 2 = A2*C = 42.833*$1.25 = $53.5413

- The amount saved by the company by choosing to make 50 Box 2 as compared to 50 Box 1:

               Amount saved = 50*(Cost of box 1 - Cost of box 2)

                                         = 50*( 54.375 - 53.5413 )

Question:

An aquarium tank can hold 6600 liters of water. There are two pipes that can be used to fill the tank. The first pipe alone can fill the tank in 55 minutes. The second pipe can fill the tank in 66 minutes by itself. When both pipes are working together, how long does it take them to fill the tank?

Given Information:

Time to fill tank by first pipe = 55 minutes

Time to fill tank by first pipe = 66 minutes

Total capacity  of tank = 6600 liters

Required Information:

Time required to fill tank when both pipes are working together = ?

Answer:

Time required to fill tank when both pipes are working together = 30 mins

Step-by-step explanation:

The rate of filling the tank of the first pipe is,

first pipe = [tex]\frac{6600}{55} = 120[/tex] [tex]L/m[/tex]

The rate of filling the tank of the second pipe is,

second pipe = [tex]\frac{6600}{66}= 100[/tex] [tex]L/m[/tex]

Let x is the time to fill the tank when both pipes are used so the equation becomes,

[tex]120 + 100 = \frac{6600}{x}[/tex]

[tex]120x + 100x = 6600[/tex]

[tex]220x = 6600[/tex]

[tex]x = \frac{6600}{220}[/tex]

[tex]x = 30[/tex] [tex]mins[/tex]

Therefore, it would take 30 minutes to fill the entire tank when both pipes are used to fill the tank.
