If you do cross multiplication you would get
60x=1800
x=30 to be exact so the answer is choice d
Answer:
441
Step-by-step explanation:
If this is a rectangle, meaning the width and the legnth is different, there is no way in solving this.
However, if it is a square, meaning all the sides are the same,
we can know that every side is 21 inches long.
An area is the width times the length, which is both 21 in this case.
21 times 21 = 441.
441 inches squared.
Answer:
20 days
Step-by-step explanation:
Expected Task duration
= (O + 4 M + P)/6
Where O = best case scenario = 15 days
P = worst case scenario = 25 days
M = Usual scenario = 20 days
Therefore, expected task duration
= [15 + 4 (20) + 25] ÷ 6
= 120 ÷ 6
= 20 days.
Therefore expected task duration is 20 days.
So you start off by seeing how many times 10 can go into 38, it would be 3 times and then your left with 8/10 and if you divide those by 2 you should get 4/5. so your final answer would be 3 4/5
Answer:
Willhelm was solving a problem in which we had to find the answer to 10(6) and then 15(4). This is why he counted 10 6 times, and then 15 4 times. I hope this helps :)
