Step-by-step explanation:

⇒ [tex]\frac{4x^{2}- 9 }{x^{2}-4x-5 }[/tex] ÷ [tex]\frac{4x - 6}{x^{2} - 1}[/tex]

⇒ [tex]\frac{4x^{2}- 9 }{x^{2}-4x-5 }[/tex] × [tex]\frac{x^{2}-1 }{4x-6}[/tex]

⇒ [tex]\frac{(2x+3)(2x-3)}{(x-5)(x+1)}[/tex] × [tex]\frac{(x+1)(x-1)}{2(2x-3)}[/tex]

⇒ [tex]\frac{(2x+3)(x-1)}{2(x-5)}[/tex] [∴ → Final Answer]

Answer:

68

Step-by-step explanation:

The 22-degree angle plus angle x is equal to the right angle opposite of it. A right angle is equal to 90 degrees. Therefore, we know that 22 + x = 90.

22 + x (- 22) = 90 (- 22)

x = 68

Therefore, angle x equals 68 degrees.

I hope this helps! Have a lovely day!! :)

Frequency for the interval 86 - 88 in the given histogram is equals to 10.

" Frequency is defined as the representation of occurrence of any particular event repeatedly in fixed time interval."

According to the question,

Given histogram shows,

Students with weight between 80 - 82 = frequency 2

Students with weight between 83 - 85 = frequency 6

Students with weight between 86 - 88 = frequency 10

10 students are there having weight between 86 - 88 pounds.

Hence, Option(C) is the correct answer.

Answer:

I believe your answer would be 1794

Step-by-step explanation:

2600 - 806 = 1794

To check:

1796 (St) + 806 (chairs left) = 2600 (total chairs)

So I would think the answer is 1794

The 69% of the seats in the theatre were filled by the 6th graders on the trip if a theatre that has 2600 seats.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Total seats = 2600

The students left 806 seats vacant.

Number of students(occupied seats = 2600 – 806 = 1794

A percentage of the seats in the theatre were filled by the 6th graders on the trip:

= (1794/2600)×100

= 0.69×100

= 69%

Thus, the 69% of the seats in the theatre were filled by the 6th graders on the trip if a theatre that has 2600 seats.

Answer:

Your answer to your question is 80

Answer:

72 cm³

Step-by-step explanation:

We can use the formula for a triangle prism's volume to solve.

V = [tex]\frac{B*H*L}{2}[/tex]

-> B is the base, H is the height, L is the length

-> Think of the area of a triangle. It is the same formula, but we also multiply by the length.

V = [tex]\frac{B*H*L}{2}[/tex]

V = [tex]\frac{3*4*12}{2}[/tex]

V = [tex]\frac{144}{2}[/tex]

V = 72

Answer:

125

Step-by-step explanation:

If it takes 25 minutes for 1/6 to be filled, then 25 minutes = 1/6 of the pool

To fill the pool then we need to find 6/6

25 x 6 = 150 so that is how much water is in the pool when it is full

150 - 25 minutes, because 1/6 is already full, means it takes 125 minutes longer.
