Janet can make 1/2 of a necklace in 20 minutes. At this rate, how many necklaces can Janet make in 2 hours?

Answers

Answer:

3 necklaces

Step-by-step explanation:

2 hours = 120 minutes

1 necklace in 40 minutes

120/40 = 3

3 necklaces

Answer:

3 necklaces

Step-by-step explanation:

2 hours needs to be in the same units as the 20 minutes

2 hours = 2 * 60 minute = 120 minutes

Now we can use ratios to solve

1/2 necklace           x necklaces

-------------------- = ----------------

20 minutes              120 minutes

Using cross products

1/2 * 120 = 20x

60 = 20x

Divide by 20

60/20 = 20x/20

3= x

i believe it is 231 yd squared

Step-by-step explanation:

Answer:

1. 231 yd²

2. 78 ft²

3. 28 inches

4. 57.5 centimeters

5. 258 cm²

Step-by-step explanation:

That is not geometry, but here are your answers.

A = bh

A = 13.2 × 17.5

A = 231 yd²

[tex]A=\frac{bh}{2}[/tex]

[tex]A=\frac{(13)(12)}{2}[/tex]

[tex]A=\frac{156}{2}[/tex]

A = 78

[tex]b=2\frac{A}{h}[/tex]

[tex]b=2\frac{364}{28}[/tex]

b = 28

[tex]h=2\frac{A}{a+b}[/tex]

[tex]h=2\frac{5405}{65+123}[/tex]

[tex]h=2\frac{5405}{188}[/tex]

[tex]h=2(28.75)[/tex]

h = 57.5

A = a²

A = 12²

A = 144 cm²

12 ÷ 2 = 6

[tex]A=\frac{(h)(b)}{2}[/tex]

[tex]A=\frac{114}{2}[/tex]

A = 57

57 cm² + 57 cm² = 114 cm²

114 cm² + 144 cm² = 258 cm²
