Answer:
y = 12
Step-by-step explanation:
Looking at the large triangle
tan 30 = opposite / adjacent
tan 30 = 4 sqrt(3)/ y
Multiply each side by y
y tan 30 = 4 sqrt (3)
We know tan 30 = sqrt(3)/3
y * sqrt(3)/3 = 4 sqrt(3)
Multiply each side by 3/ sqrt(3) to isolate y
y * sqrt(3)/3 * 3/ sqrt(3) = 4 sqrt(3) * 3 /sqrt(3)
y = 12
Answer:
Step-by-step explanation:
We are given the following in the question:
Population D:
30% of the turtles have a shell length greater than 2 feet.
Sample size,
Number of turtles that had shell length greater than 2 feet,
Sample proportion:
Population E:
20% of the turtles have a shell length greater than 2 feet.
Sample size,
Number of turtles that had shell length greater than 2 feet,
Sample proportion:
We have to find the difference between the sample proportion.
Difference in sample proportion =
3/4 of 2/3 will pass
3/4 of 2/3 = (3/4) * (2/3) = 6/12 = 1/2
Half of them will pass.
Answer:
HL
Step-by-step explanation:
It's a right triangle.
Part 1:
Proportion: 1/2 per foot.
Solve: The tree is 10 feet tall.
Solution in a sentence: To solve this, you take the shadows length, and double it to get objects actual height.
Part 2:
Proportion: 2 male horses to 3 female horses
Solve: There are 18 Female Horses.
Soulution in a Sentence: To solve this, you take the amount of male horses, divide it in half, then multiply it by 3 to get the answer.
Part 3:
Proportion: 3 drops to every 4 pints of water.
Solve: There are twelve drops in the 16 pints of water.
Solution: Every four pints of water, there is three drops. So you take the sixteen pints, divide it by four. Then, multiply it by three to get you answer.
