Hello here is a solution :
there is 0.015 kilos in 15 grams. if each can weighs 0.015 and he gets paid 50p per KG. 0.015 X 66 will get you 1 kilogram! so you have 66 cans to get 1 kg worth of cans. so there is 15 dollars and each kg is worth 50p- so 66 cans is = 50p
and there is 2 KG per dollar so 15 X 2 is 30! and then 66 X 30 is 1980!
66 for each KG and 30 represents how many 50p's are needed for 1 dollar!
so that is 1980 cans to get 15 dollars!
Answer:
Both people did the same type of general question, but Jenna's method uses the distributive property to do it mentally.
Step-by-step explanation:
Jenna's Method: Uses distributive property to break it all down and do it mentally.
Mia's Method: She broke the equation down so much that the answer will be more complex to find.
Distance between (2, 5) and (8, 5) = 8 - 2 = 6
Distance between (8, 5) and (8, 3) = 5 - 3 = 2
Distance between (8, 3) and (2, 3) = 8 - 2 = 6
Distance between (2, 3) and (2, 5) = 5 - 3= 2
Total length of border = 6 + 2 + 6 + 2 = 16
Answer:
20 yards
Step-by-step explanation:
The area of a square is calculated by multiplying its height by its base. Because they are the same in a square, the area of a square is obtained by squaring one of its sides. Let's call the sides 'x'. Then we can express the area of the garden as x^2=400.
From here we simply need to square root both sides which gives us:
x=20
Therefore the length of one side of the garden is 20 yards.
Hope this helped!
