Answer:
13
Step-by-step explanation:
subtract 1 on both sides
then divide by 3
to get 13
Surface area of a square pyramid is the area of the base + 4 times the area of one of the slanted sides.
Area of base = side length * side length
Area of side = (1/2) * side length * slant height
Don't forget that you have to multiply the area of the side by 4!
Step 1: 12 x 12 = 144
Step 2: 12 x 20 = 240 divided by 2 = 120
Step 3: 144 + 120 x 4
2^3=2*2*2
2*2*2+4*8
8+32
=> 40
Answer:
d = 3 meters
Step-by-step explanation:
d = rt where d is the distance t is the time and r is the constant of proportionality
d = 18t
Changing 10 minutes to hours
10 minutes * 1 hours / 60 minute = 1/6 hour
d = 18 * 1/6 hour
d = 3 meters
There isn't any choices given in this problem but I can give you a tip to answer these kinds of problem. When you say independent, it means that the equation cannot be algebraically altered to result to 3x + 4y = 8. So the equation 6x + 8y = 16 is not an independent equation since when you divide each side by 2 it will result to 3x + 4y =8. You get the idea. <span />
