Rami is sketching drawings for his friends. He creates 5 sketches each hour. Write a ratio, in lowest terms, that compares the number of sketches Rami makes to the amount of time, in minutes

1:12

Step-by-step explanation:

Rami creates 5 Sketches each hour.

Now using the standard time conversion unit,

1 hour = 60 Minutes

We want to write a ratio that compares the number of sketches made by Rami to her time in Minutes.

This is given as:

5 Sketches : 60 Minutes.

To reduce it to its lowest form, divide both sides of the ratio by 5.

:

1:12

The ratio is 1:12

The interpretation of this is that Rami makes 1 Sketch for every 12 Minutes.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
