If the legs of both triangles are supposed to be proportional then they would be equal in length because that's what proportional means
so if the legs of one triangle are 4.5 and 1.5 then the other triangle "if proportional" would have legs with the same measurements which are 4.5 and 1.5
hope this answers your question
Yes.
4 cups of flour/3 cups of milk= 1.33 flour/milk
2 cups of flour/ 1.5 cups of milk= 1.33 flour/milk
As you can see, these are the same ratios.
Answer:
Leah has 48 marbles.
Step-by-step explanation:
Represent the number of marbles that each person has by L and D.
Leah has 28 more marbles than Dan: L = D + 28.
Then (1/3)L = (4/5)D. Here the LCD is 15, and so multiplying this equation by 15 will remove the fractions: 15(1/3)L = 15(4/5)D.
Therefore, 5L = 12D, and D = 5L/12.
Then, since L = D + 28, L = (5/12)L + 28, or
12L = 5L + 336, or
7L = 336, or
L = 336/7 = 48.
Leah has 48 marbles. That means that Dan has 20 marbles.
Simply multiply the 475.13 miles to the 5.25 hours to get 2,494.43
