O 6 minutes
O 60 minutes
180 minutes
O 5,400 minutes

Answers

Answer 1
6 minutes per window. Multiply 3(60) and then divide by the number of windows (30)
Answer 2

Answer:

A. 6 minutes

Step-by-step explanation:

6 minutes is 1/10 of an hour.

60 minutes is 1 hour.

5,400 minutes is 90 hours.

3 hours is 180 minutes. You can solve this as a proportion:

[tex]\frac{180}{30} =\frac{x}{1}[/tex]

Cross multiply to get 30x = 180. x = 6.

Hope it helps!

Given m||n, find the value of x and y

Answers

Answer:

x = 8

y = 29

Step-by-step explanation:

8x - 11 = 9x - 19

x - 19 = -11

x = 8

2y - 5 = 9x - 19

2y - 5 = 9(8) - 19

2y - 5 = 72 -19

2y - 5 = 53

2y = 58

y = 29

Use synthetic division to find all the factors of this polynomial

4x^3+5x^2-18x+9

Answers

Answer:

(x-1)(4x-3)(x+3)

Step-by-step explanation:

The factor of the polynomial 4x³ + 5x² – 18x + 9 will be (4x – 3), (x + 3), and (x – 1).

What is a factorization?

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The polynomial is given below.

⇒ 4x³ + 5x² – 18x + 9

Then the factor of the polynomial will be

⇒ 4x³ – 3x² + 8x² – 6x – 12x + 9

⇒ x²(4x – 3) + 2x(4x² – 3) – 3(4x – 3)

⇒ (4x – 3)(x² + 2x– 3)

⇒ (4x – 3)(x² + 3x – x – 3)

⇒ (4x – 3)(x + 3)(x – 1)

More about the factorization link is given below.

None of the sides are parallel.

Step-by-step explanation:

Quadrilaterals are all figures or shapes bounded by four sides. Some common examples are: square, rectangle, trapezium, rhombus, parallelogram etc.

Two or more lines are said to be parallel, if none of the lines meet when extended till infinity. i.e they are at [tex]180^{o}[/tex] to one another.

Step-by-step explanation:

Not sure if there is more to this question but here is what I assume:

We want to find the first 7 terms of this equation given 3n+4

Assuming we are starting at 0 we plug 0 in for n.

3(0) + 4 → 4

So our first answer is 4

We continue by pugging in the next numbers after that to get to the first 7 terms

3(1) + 4 → 7

3(2) + 4 → 10

3(3) + 4 → 13

3(4) + 4 → 16

3(5) + 4 → 19

3(6) + 4 → 22
