Answer 2

Answer: A

Step-by-step explanation:

Let the length side of the TV = a

The width of the TV = b

The diagonal of a TV = c

In a 30-60-90 right triangle,

We have cos(30°) = [tex]\frac{\sqrt{3}}{2}[/tex] and sin(30°) = [tex]\frac{1}{2}[/tex]

Given that c = 28 inches:

sin(30°) = [tex]\frac{b}{c}[/tex]

[tex]\frac{1}{2} = \frac{b}{c}[/tex]

[tex]b = \frac{1}{2} \times 28 = 14[/tex]

That is, the width of the TV = 14 inches

cos(30°) = [tex]\frac{a}{c}[/tex]

[tex]\frac{\sqrt{3}}{2} = \frac{a}{c}[/tex]

[tex]a = \frac{\sqrt{3}}{2} \times 28 = 14\sqrt{3}[/tex]

That is, the length of the TV = 14√3 inches

So the exact width and length of the TV are 14 inches and 14√3 inches.

Therefore, option A is the correct answer

Arlington High School recently installed a new black-box theatre for local productions. They only had
room for 14 rows of seats, where the number of seats in each row constitutes an arithmetic sequence starting
with eight seats and increasing by two seats per row thereafter. How many seats are in the new black-box
theatre? Show the calculations that lead to your answer.

Answers

Answer: ANSWER*0.15 (15% is 15/100 or 0.15)

Step-by-step explanation:

An arithmetic sequence is a sequence where the difference between each consecutive term is the same.

The number of seats in the new black box is 294.

What is an arithmetic sequence?

It is a sequence where the difference between each consecutive term is the same.

Example:

2, 4, 6, 8 is an arithmetic sequence.

We have,

Number of rows = 14

n = 14

a = 8.

d = 2

So,

The number of seats in the 14 rows is,

8, 10, 12, 14,.........

Now,

The sum of the arithmetic sequence.

= n/2 [2a + (n - 1)d ]

The number of seats in the new black box.

= 14/2 [ 2x8 + (14 - 1)2 ]

= 7 [ 16 + 26 ]

= 7 x 42

= 294

Thus,

The number of seats in the new black box is 294.

a bus travelled 63 km in first hour 60 km in second hour and 57 km in third hour what was te Average distance covered in one hour​

Answers

The average speed is the ratio of the total distance to the total time. Then the average distance covered in one hour​ by the bus is 60 kilometers.

What is speed?

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{Distace }{Time }[/tex]

A bus traveled 63 km in the first hour 60 km in the second hour and 57 km in the third hour.

Then the average speed will be

[tex]\rm Average \ speed = \dfrac{Total \ distace }{Total \ time }\\\\\\Average \ speed = \dfrac{63 + 60 +57}{1+1+1}\\\\\\ Average \ speed = \dfrac{180}{3}\\\\Average \ speed = 60 \ km/h[/tex]

The average distance covered in one hour​ by the bus is 60 kilometers.

b. At the circus, three adult tickets and five child tickets cost $51, and five adult tickets
and two child tickets cost $47. Which system of linear equations below can be used to
determine the price of each ticket?
Let x represent the cost of an adult ticket, and let y represent the cost of a child ticket.

Answers

Answer: x = $7, y = $6

Step-by-step explanation:

Let x be the cost of an adult ticket

Let y be the cost of a children's ticket

Translate these sentences to algebra:

At the circus, three adult tickets and five child tickets cost $51: 3x + 5y = 51

Five adult tickets and two child tickets cost $47: 5x + 2y = 47

Now we have two equations. Let's use substitution to solve.

3x + 5y = 51

3x = 51 - 5y

.: x = 17 - 5y/3

Now substitute this value of x into the second equation to find the numerical value of y:

5(17 - 5y/3) + 2y = 47

85 - 25y/3 + 2y = 47

-19y/3 = -38

-19y = -114

.: y = 6

Now find x:

x = 17 - 5y/3

x = 17 - 10

.: x = 7

So an adult ticket costs $7, and a child ticket costs $6 :)
