Answer:
Step-by-step explanation:
we know that
The surface area of the cube is equal to the area of its six square faces
so
where
b is the length side of the cube
we have
substitute
To make this a bit easier we can convert the fractions to decimals, then add them up to find out how much flour they originally had. Rashan bought 3 7/10 pounds of flour, which becomes 3.7 pounds. Diego bought 2 3/4 pounds of flour, which becomes 2.75 pounds of flour. In total they both had 3.7 + 2.75 = 6.45 pounds of flour.
Now they used 4 3/5 pounds to bake some bread, which becomes 4.6 pounds. To find out how much flour they have left, we subtract the 4.6 from 6.45, which equals 1.85 pounds of flour left.
Hello,
The two lights flash at the same time every 18 min
at 8:00 h=480 min =480+0*36
at 8:36 h=516 min =480+1*36
...
54 is not divisible by 36
60+12=72 = 2*36 yes
60+24=84 not
120+24=4*36 yes
180+18=198 not
So 2 times are correct 9:12 and 10:24
Answer G
475% = .475 = 475/100
19/4 (simplified)
therefor the answer in 4 3/4
The formula is right there in the question. Just write '16' in place of 'b' and write '5' in place of 'h', then do the multiplication and you have the area. / / / If you don't get 40 square mm then you have a mistake somewhere.
