She has 445 left after the bear ate some so
21 × 12 = 252
252 + 445 = 697 acorns
she should maybe bother the bear so he can't hibernate, or steal his food so he knows what it's like
(3782 - 192) : 2 = 1795 (first number)
1795 + 192 = 1987 ( second number)
--------------------------
1987 - 1795 = 192
1987 + 1795 = 3782
Answer:
$360. (I believe so, anyways.)
Step-by-step explanation:
Original Price x Discount % / 100
Discount = 600 × 40/100
24000/100
$600 - $240
Final Price = $360

ANSWER
The length of the altitude is
units
<u>EXPLANATION</u>
The altitude of a triangle is the vertical height of the triangle.
From the diagram the altitude is ![a](https://tex.z-dn.net/?f=a)
Method 1: We can use Pythagoras theorem to find ![a](https://tex.z-dn.net/?f=a)
![6^2=a^2+3^2](https://tex.z-dn.net/?f=6%5E2%3Da%5E2%2B3%5E2)
![6^2-3^2=a^2](https://tex.z-dn.net/?f=6%5E2-3%5E2%3Da%5E2)
![36-9=a^2](https://tex.z-dn.net/?f=36-9%3Da%5E2)
![27=a^2](https://tex.z-dn.net/?f=27%3Da%5E2)
We take the square root of both sides,
![\sqrt{27}=a](https://tex.z-dn.net/?f=%5Csqrt%7B27%7D%3Da)
![\sqrt{9\times3}=a](https://tex.z-dn.net/?f=%5Csqrt%7B9%5Ctimes3%7D%3Da)
![\sqrt{9} \times \sqrt{3}=a](https://tex.z-dn.net/?f=%5Csqrt%7B9%7D%20%5Ctimes%20%5Csqrt%7B3%7D%3Da)
![3\sqrt{3}=a](https://tex.z-dn.net/?f=3%5Csqrt%7B3%7D%3Da)
Method 2 Using Trigonometry
![sin(60\degree)=\frac{a}{6}](https://tex.z-dn.net/?f=sin%2860%5Cdegree%29%3D%5Cfrac%7Ba%7D%7B6%7D)
![6sin(60\degree)=a](https://tex.z-dn.net/?f=6sin%2860%5Cdegree%29%3Da)
![a=6\times \frac{\sqrt{3}} {2}](https://tex.z-dn.net/?f=a%3D6%5Ctimes%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%20%7B2%7D)
![a=3\sqrt{3}](https://tex.z-dn.net/?f=a%3D3%5Csqrt%7B3%7D)
