Answer:
a. 3.2 cm
b. 6.25 km
Step-by-step explanation:
a.
(4 km)/(5 km) = 0.8
4 km is 0.8 of 5 km, so in the map it is 0.8 of 4 cm.
0.8 * 4 cm = 3.2 cm
Answer: 3.2 cm
b.
(5 cm)/(4 cm) = 1.25
5 cm is 1.25 times 4 cm, so it represents 1.25 * 5 km.
1.25 * 5 km = 6.25 km
Answer: 6.25 km
32 homes. divide 96 by 3 because the 96 homes each took 3 kittens
William is 17 years old and Charmaine is 14 years old.
Step-by-step explanation:
Let x be the age of William and y be the age of Charmaine
Then
William is 3 years, older than Charmine.
x = y+3 Eqn 1
The sum of 3 times Charmaine's age and 2 times William's age is 76.
2x+3y = 76 Eqn 2
Putting x = y+3 in Eqn 2

Hence,
William is 17 years old and Charmaine is 14 years old.

Answer:
8 green picks
Step-by-step explanation:
Since this problem is a ratio that also gives a total, setting up equivalent ratios in a table with the total would be a good way to find the answer. Since there is 1 orange pick for every 2 green picks and there are a total of 12 picks, we can set up the following:
Orange 1 2 3 4 5
Green 2 4 6 8 10
Total 3 6 9 12 15
You can see from the table, that when there are 12 total picks, 4 of them are orange and 8 of them are green.
