Check the picture below.
so the lateral area of the pyramid is really just the area of four triangles whose base is 10 and height is also 10, now, we're excluding the bottom because that's not lateral area.
![\stackrel{\textit{area of four triangles}}{4\left[\cfrac{1}{2}(\stackrel{b}{10})(\stackrel{h}{10}) \right]}\implies 2(100)\implies \text{\LARGE 200}~ft^2](https://tex.z-dn.net/?f=%5Cstackrel%7B%5Ctextit%7Barea%20of%20four%20triangles%7D%7D%7B4%5Cleft%5B%5Ccfrac%7B1%7D%7B2%7D%28%5Cstackrel%7Bb%7D%7B10%7D%29%28%5Cstackrel%7Bh%7D%7B10%7D%29%20%5Cright%5D%7D%5Cimplies%202%28100%29%5Cimplies%20%5Ctext%7B%5CLARGE%20200%7D~ft%5E2)
Answer:
The student's mean score in the class is 80.6
Step-by-step explanation:
we know that
To find out the student's mean score in the class, multiply each score by its worth and adds the numbers

therefore
The student's mean score in the class is 80.6
0.7 divided by 0.35 = 2 is the correct answer :))
Answer:
y = 3
Step-by-step explanation:
Let's start with the left side of the equation.
5(y-2)-2= 2(y+1)-5
5y-10-2= 2(y+1)-5
Now let's solve the right side
5y-10-2= 2y+2-5
5y-12= 2y-3
-2y -2y
3y-12=-3
+12 +12
3y = 9
3y/3 = 9/3
y = 3
hope this helps!
