Answer:

420 $40 tickets.

Step-by-step explanation:

Here is the explanation.

1. As 700 tickets cost a total of $33600, the average cost of each ticket is $48.

2. As there are 700 total tickets with each costing $40 or $60, we can use the total cost ($33600) to define the amount of each ticket.

3. If there were to be 420 $40 tickets, there will be 280 $60 tickets.

4. This means that the cost of each price of tickets ($40 and $60) will be distributed evenly among the total price, each costing $16800.

5. 420 x 40=16800 280x60=16800

6. There are 420 $40 tickets sold at the concert.

Answer:

428 square ft

Step-by-step explanation:

to do this you can break the shape up into multiple pieces

you can do it this way

the top left part of the polygon could be one shape

9 by 10

this is because if the left side is 23 and part of the left side is 13 the leftover part is 10

then the bottom is 13 by 26

then you multiply and add them together

(9 * 10) + (13 * 26) = 90 + 338

then you add

90 + 338 = 428

the answer is 428 square ft

Answer:

f(g(x)) = 9x + 1

Step-by-step explanation:

f(x) is defined as 3x + 1.  To find f(g(x)), substitute g(x) = 3x for x in f(x):

f(g(x)) = 3(g(x)) + 1 = 3(3x) + 1 = 9x + 1

or:

f(g(x)) = 9x + 1

Answer:

110

Step-by-step explanation:

The required result from the encryption of the number $3$ is 110.

Given that,
Carlos wants to send Cecil a message encrypted with RSA. Cecil has published his public encryption exponent $5$ and his public modulus $133$. When Carlos encrypts the number $3$ with this system, what is the result is to be determined.

In mathematics, it deals with numbers of operations according to the statements.

Here,
Encrypt message M = 3
Public key = (133, 5)
When [tex]M^e[/tex] = [tex]3^5[/tex] = 243 divided by 133 gives the remainder of C = 110,

Thus, the required result from the encryption of the number $3$ is 110.

Answer:

3x/2 =6

Step-by-step explanation:

The distance between the dog and cat is 6 miles. Then the equation is 30x = 6 or x = 0.2.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{ Time }[/tex]

Bobby's cat runs at x mph. Bobby's dog runs twice as fast as his cat.

The speed of a cat is x. Then the speed of the dog is 2x.

The distance traveled by the cat in 30 minutes will be

[tex]\rm D_c = 30 \times x\\\\D_c = 30 \ x[/tex]

The distance traveled by the dog in 30 minutes will be

[tex]\rm D_d = 30 \times 2x\\\\D_d = 60 \ x[/tex]

Suppose Bobby's cat and dog were 6 miles apart after 30 minutes.

[tex]\rm D_d - D_c \ \ = 6\\\\60x - 30x = 6\\\\30x = 6[/tex]

Step-by-step explanation:

Answer: m = -⁸⁄₅

PLz mark brsinliest:)

The slope of the line containing the points (5,-8) and (-5,8) is -8/5 after using the concept of the slope of a line.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The line containing the points (5,-8) and (-5,8)

A straight line is a combination of endless points joined on both sides of the point.

As we know from the formula of the slope:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\rm m =\dfrac{8-(-8)}{-5-5}[/tex]

m = (8 + 8)/(-10)

m = -16/10

m = -8/5

Thus, the slope of the line containing the points (5,-8) and (-5,8) is -8/5 after using the concept of the slope of a line.

AM switches to PM at 12 PM.

so, we need to calculate the time from 9:23 am to 12 pm, and then from 12 pm to 2:06 pm, and then add both for the overall answer.

the first full hour after 9:23 am is 10 am. from there it is 2 hours to 12 pm.

how many minutes from 23 minutes to 60 (of the next full hour) ? 60 - 23 = 37 minutes.

so, it is 2 hours and 37 minutes until 12 pm.

and from 12 pm to 2:06 pm it is 2 hours and 6 minutes.

the total time is then

2 hours 37 minutes + 2 hours 6 minutes =

= 2 + 2 hours 37 + 6 minutes = 4 hours 43 minutes

FYI

if the sum of the minutes would have been larger than 60 (like e.g. 53 + 12), then we would have had to add another hour as a carry over, and take the remainder of minutes/60 as minutes.

e.g.

2 hours 53 minutes

3 hours 12 minutes

would sum up to

5 hours 65 minutes = 6 hours 5 minutes

Solving

Before starting to solve the question we can easily identify that we need to divide the total number by the amount of equal pieces.

The reason we are going to divide is because when you divide a number you are distributing it into equal groups.

Surface Area:

A triangular prism is made up of 3 rectangles and 2 triangles.

Area of a rectangle = base x height

Area of a triangle = 1/2 x base x height

Rectangle: 5.6 x 2.7 = 15.12

All 3 rectangles: 15.12 x 3 = 45.36

Triangle: 1/2 x 2.7 x 2.3 = 3.105

Both triangles: 3.105 x 2 = 6.21

Surface Area: 45.36 + 6.21 = 51.57 mm^2

Volume:

Volume of a triangular prism = base area x height

Triangle area = 3.105

Height = 5.6

Volume: 3.105 x 5.6 = 17.88mm^3

The diagonal of the square MISA bisect the angle at the vertices

The values of r, s and t are r  = 2.6, s = 34.6 and t = 6.9

The given parameters are:

MPA = (2s + 3t)º

ISP = (4r + s)°

MIS = (3s – 2t)º

The angle between the diagonal of a square is 90 degrees.

So, we have:

2s + 3t = 90

Multiply by 2

4s + 6t = 180

The angle at the vertices of the square is 90 degrees.

So, we have:

3s - 2t = 90

Multiply by 3

9s - 6t = 270

The diagonal bisect the angle at the vertex.

So, we have:

4r + s = 45

Rewrite the equations

4s + 6t = 180

9s - 6t = 270

4r + s = 45

Add the first and the second equations

4s + 9s + 6t - 6t = 180 + 270

13s= 450

Divide by 13

s = 34.6

Substitute s= 34.6 in 4r + s = 45 and 3s - 2t = 90

4r + 34.6 = 45

Solve for r

r  = 2.6

3 * 34.6 - 2t = 90

Solve for t

t = 6.9

Hence, the values of r, s and t are r  = 2.6, s = 34.6 and t = 6.9
