Answer:
A.)=24.78
B.)=26
C.)=7.33
D.)=25.44
Step-by-step explanation:
A.)11.40+13.38=24.78
B.)11+15=26
C.)4.18+3.15=7.33
D.)10.92+14.52=25.44
To find the surface are youd have to multiply 6 1/2 by 6, because a cube has 6 total sides. so the answer would be 6•6.5 which equals 39
Answer:
12km/h
Step-by-step explana:
Let's call the total distance 2a from which we can calculate t1 equivalent to the first half of the distance a/10 similar to t2 is a/15 from which the total time is a/6 . We have the average speed equal to the total distance dduowcngf divided by the total inferred time by 2a/(a/6) which equals 12km/h
there should be a cross multiplication
3(8x)=2
expanding bracket
24x=2
multiple both sides by 24
x=1/12
You said that (1/2) / N = 1/3
Multiply each side by 'N' : (1/2) = 1/3 N
Multiply each side by 3 : 3/2 = N
or 1-1/2 = N .
