Step-by-step explanation:
By Pythagoras' Theorem, 6^2 + 8^2 = x^2.
x^2 = 36 + 64 = 100, x = 10.
I'm not sure what the ray exactly is but some examples of ray names are ray RT or ray TR. You basically switch the letters.
These two have different denominators, so you find the least common multiple. This problem goes to be 2/8+5/8, which equals 7/8。
Answer:
125,000 * 1.0625^t years
Step-by-step explanation:
compound interest = increase in amount
100 + 6.25 = 106.25
106.25/100 = 1.0625
therefore, 125,000 * 1.0625^years
Answer:
20 adults and 10 children
Step-by-step explanation:
We need to find the total amount of adults and children for 30 total people (adults + children) and only 100$ for them. 30 adults is 120$. We need to take off double the amount of money that would bring it to 100$ because the cost for each child is half of an adult. That way, we have 80$ of adults, and when we fill in the rest with children, we get to 100$ total and 30 total people.
