Subtract 5 (Cameron) and 2 (Karlee) from 49.
Why: Denise's age is basically the basic number. Karlee would be 2 years older, so subtract 2 from 49. You get 47. Cameron is 5 years older than Denise, so subtract 5. You get 42 and divide that by 3 since there are 3 people.
49 - 7 = 42
42 divide by 3 = 14
Check:
14 + 5 = 19
14 + 2 = 16
14 + 0 = 14
19 + 16 + 14 = 49
19 (Cameron) - 16 (Karlee) = 3 years older
16 (Karlee) - 14 (Denise) = 2 years older
19 (Cameron) - 14 (Denise) = 5 years older
Hopes this helps!
Answer: 80
Step-by-step explanation:
We can use the formula
, where
are the lengths of the diagonals.
By the distance formula,
![AC=\sqrt{(-2-2)^{2}+(-1-7)^{2}}=\sqrt{16+64}=4\sqrt{5}\\BD=\sqrt{(-8-8)^{2}+(-1-7)^{2}}=\sqrt{256+64}=8\sqrt{5}](https://tex.z-dn.net/?f=AC%3D%5Csqrt%7B%28-2-2%29%5E%7B2%7D%2B%28-1-7%29%5E%7B2%7D%7D%3D%5Csqrt%7B16%2B64%7D%3D4%5Csqrt%7B5%7D%5C%5CBD%3D%5Csqrt%7B%28-8-8%29%5E%7B2%7D%2B%28-1-7%29%5E%7B2%7D%7D%3D%5Csqrt%7B256%2B64%7D%3D8%5Csqrt%7B5%7D)
So, the area is ![\frac{(4\sqrt{5})(8\sqrt{5})}{2}=\boxed{80}](https://tex.z-dn.net/?f=%5Cfrac%7B%284%5Csqrt%7B5%7D%29%288%5Csqrt%7B5%7D%29%7D%7B2%7D%3D%5Cboxed%7B80%7D)
Answer:
430 + 16h
Step-by-step explanation:
They are staying for a week ($430)
They are renting both a kayak ($7 per hour) and paddle board ($9 per hour), without defining the amount of hours. Create a variable, for example H for hours.
To create the expression, take the $430, the $7 per hour and $9 per hour, or 430 + 16h.
