You are traveling at 75 miles per hour on a straight stretch of highway in Nevada. It is noon now. When will you arrive at the n
Levart [38]
Right now it is noon..... you are traveling 75 miles per hour meaning you'll move 75 miles... every hour. so you're 120 miles away so now we need to figure out the time.... to do this we already know 1 hour is 75 miles so now you can subtract one hour 120-75= 45 so 75 per hour, what would 45 be?..... so we can set up a fraction to figure out how long it takes to travel one minute.... so 60/75(the 60 is for minutes in an hour). which is .8 of a second to travel one mile so.... now you can multiply to check your work. .8*75=60 mins.... so now multiply.8*45(miles left)=36 so you'd get there at 1:36 it would take an hour and 36 mins to get to your destination going 75mph

The scale drawing of a rectangular room measures 10cm long by 6cm wide. The actual width of the room is 9 metres. What is the ac
Snezhnost [94]

Answer:

48 meters

Step-by-step explanation:

The first thing is to calculate the scale, since we know both widths it is possible:

we pass the 9 meters to centimeters = 900 cm

900/6 = 150

So the scale would be 1: 150

Which means that the length is 150 times bigger.

10 * 150 = 1500cm or what equals 15m

the perimeter is the sum of all the sides, therefore:

P = 15 + 15 + 9 + 9

P = 48

Which means that the perimeter of the room is 48 meters
