shepuryov [24]

Answer:

\frac{3}{2}

Step-by-step explanation:

Given the expression:

\frac{n+3}{2n-6} \div \frac{n+3}{3n-9}

We are to find the quotient as shown:

= \frac{n+3}{2n-6} \div \frac{n+3}{3n-9}  \\\\= \frac{n+3}{2n-6} \times \frac{3n-9}{n+3} \\\\=  \frac{n+3}{n+3} \times \frac{3n-9}{2n-6}\\\\= 1  \times \frac{3(n-3)}{2(n-3)}\\\\= 1 \times  \frac{3}{2} \\\\= \frac{3}{2}

Hence the correct answer is \frac{3}{2}

Someone please pass the answers to this
arsen [322]

Answer/Step-by-step explanation:

1. The figure is composed of a triangle and a rectangle.

Area of the triangle = ½*base*height

base = 4 ft

height = 12 - 8 = 4ft

Area of triangle = ½*4*4 = 8 ft²

Area of rectangle = length * width

Length = 8 ft

Width = 4 ft

Area of rectangle = 8*4 = 32 ft²

✔️Area of the figure = 8 + 32 = 40 ft²

2. The figure is composed of a semicircle and a triangle

Area of the semicircle = ½(πr²)

radius (r) = 3 cm

π = 3

Area = ½(3*3²) = 13.5 cm²

Area of triangle = ½*base*height

base = 3*2 = 6 cm

height = 6 cm

Area = ½*6*6 = 6 cm²

✔️Area of the figure = 13.5 + 6 = 19.5 cm²

Seven men make 21 toys in 30 minutes. How long would it take 21 men?
konstantin123 [22]

Answer:

  10 minutes

Step-by-step explanation:

Assuming men and minutes are interchangeable, 3 times as many men can be assumed to assemble the toys in 1/3 as much time.

21 men can make 21 toys in 30/3 = 10 minutes.

_____

<em>Additional comment</em>

We have to assume there are no rate-limiting steps in the process. This assumption is not always valid.
