40 because 15×4 is 60 and there is 60 minutes in an hour
Is it supposed to be a fraction or a whole number or a mixed number?
Answer:
Step-by-step explanation:
V=hb/3, where b=area of base
b=3V/h, since V=30mm^3 and h=5mm then
b=3(30)/5
b=18 mm^2
So the area of the base is 18 square millimeters.
Answer:
3x6 = 729x when ever a number has an exponnet yo have to multiply the main number to itself as many times as it says.
So in this case you had to multiply 3 by itself(3) 6 times would be
(3x) x (3x) x (3x) x (3x) x (3x) x (3x) = 729x. And of course bring the variable.
x2 So when theres a varible that is by itself for example (x) you always add a 1 in front of it. so in this case x2 would be 1x2. 1 times itself(1) 2 times would be. (1x) x (1x) = 1x
729 smaller cubes would fit inside the larger cube.
