If it can scan 72 photos in 8 minutes, it can scan 72/8 = 9 photos per minute.
So in 23 minutes, it can scan 9x23 = 207 photos
25% chance because there are 8 total “slices” and there are 2 A’s.
2/8=1/4=25%
58,800.
3600 divided by 9000 is 0.4
147,000 * 0.4 is 58,800
Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9
Hope this helps!
Make a proportion.
Do base over height;

.

h is the height of the second triangle. Solve for h.
Cross multiply.
6h = 168
h = 28
