Answer:
the right answer might be C = 2 π r
Step-by-step explanation:
yeah
The average temperature would be -2°Celsius
You just add up all the numbers, and the average of the numbers is the sum of all the numbers divided by the amount of numbers.
1+-6+14+-9+-15+8+-7=-14
-14/7=-2
Answer:
Its already in simplest form.
Answer:
b
Step-by-step explanation:
The non-fillee dots stop at the 98 row and the 0.2 column.
98 + 0.2 = 98.2
I might be wrong, but I think you could solve this using algebra (if you haven't studied algebra you probably won't understand this answer). First I would try to let Henry's age equal X (it's the unknown) and let his sister's age equal his age (X) minus three, since she's three years younger. So:
Henry's age = X
Sister's age = X - 3
Total = 180
If you knew there two ages adding them together would get 180. That's what they mean by the "product" of their ages. Since we're letting the variables represent there ages we'll add those instead.
X + X - 3 = 180. Next add the X's
2X - 3 = 180. Add 3 to both sides
2X = 183. Divide 2 into 183
X = 91.5
X - 3 = 88.5
So Henry is roughly 91 and his sister is roughly 88. They only asked for Henry's age so depending on the context you can give them his exact age or his rough age. I think I did this right, so hopefully this helps!
