A can do 1 job in 10 min. means 1/10 job per min.
B can do 1/15 job per min.
together A&B can do 1/10+1/15 =1/6 job per min.
1/6 job they spend 1 min
1 spend 1x1/(1/6) = 6 min
For the shaded bit all you need to do is 8.5 × 6.
if you are to get the other bit then do 8.5 × 8
if it is to be both then just do that and add them together
Answer:
If you are looking for the other quordinate the answer is (4,2)
Step-by-step explanation:
so you will have to start from the giving coordinate to find the next.
So, you go up to 6 and then since the 1 is positive you will turn right one time
1. perimeter = 4 and area = 1
2. permeter = 8 and area = 4
3. perimeter = 12 and area = 9
4. perimeter = 16 and area = 16
5. perimeter = 20 and area = 25
The question isn't correctly given, a possible format is in the comment below, however, the explanation will cover then concept which can be applied to different but similar
Answer:
10048576 ways
Step-by-step explanation:
We are given a question, from which we can choose aby of 4 options, this gives ua 4 possible choices for 1.
This will also apply if we have more than 1 question with the same number of options.
This can be called the product rule, as each possibility is the same of each question given :
Therefore, given 10 questions:
. We have
4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 = 4^10 = 10048576 ways
