Need help please, thanks! A map has a scale of 1 inch:18 kilometers.

Three distances on the map are listed in the chart below. Drag an actual distance into each box to match the corresponding distance on the map.

0.8 in.___________________

1.4 in.____________________

2.1 in.____________________


I don't know, please explain! :(

Answers

Given:
1 inch : 18 kilometers

Let us use the ratio and proportion method:

a:b = c:d where ad = bc

0.8 inches is 14.4 kilometers

1 : 18 = 0.8 : x
x = 0.8 * 18
x = 14.4 km

1.4 inches is 25.2 kilometers

1: 18 = 1.4 : x
x = 18 * 1.4
x = 25.2 km

2.1 inches is 37.8 kilometers

1 : 18 = 2.1 : x
x = 18 * 2.1
x = 37.8 km

Peter celebrates his birthday on the 5th and his twin sisters celebrate theirs on the 9th. Each person will have their own cake. What is the MOST appropriate word model for this problem?


A. Peter’s Age × One Twin’s Age = Total Candles Needed


B. Peter’s Age + One Twin’s Age = Total Candles Needed


C. Number of Candles in a Typical Box – Peter’s Age = Candles Needed


D. Peter’s Age + Two Times One Twin’s Age = Total Candles Needed

Answers

The answer is D because you are adding how many candles for whatever peters age is and since the twins are both the same age and get their own cake and the same amount of candles you multiply it by two

Answer:

D. Peter’s Age + Two Times One Twin’s Age = Total Candles Needed
