V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in
V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3

First draw it out. Label the angles at the corners of the triangle 60 (definition of equilateral triangles). Now draw a line from the center of the circle to the corner, splitting the corner in half. Label this line R and a corner as 30 degrees. No to find the height of this triangle, you do rsin(30). The base of this triangle is 2rcos(30). Now find the area of this mini triangle (rsin(30)*2rcos(30)/2=r/2*rsqrt(3)/2=r^2sqrt(3)/4). Now multiply this by 3 because you have 3 mini triangles... to get...

To figure out which sold the most magazines, multiply each number by 200 to find the answer. Let's start with 1/8. 200 * 1/8 = 25. Then 0.065 * 200 = 13.
3/100 * 200 = 6
200 * 0.105 = 21.
Fatima sold the most magazines.
Answer:
62
Step-by-step explanation:
96 divided by 2 = 48
48 - 14 = 34
48 + 14 = 62
34 + 62 = 96 (total cars washed)
You're welcome
