Answer:
2
Step-by-step explanation:
Factors for 14: 1, 2, 7, and 14. Factors for 16: 1, 2, 4, 8, and 16.
The greatest common factor being 2, as they both have it.
Sorry if wrong but here I go
so basically
you need to find the scale factor so
14/10=1.4 and 21/15=1.4
so I take the scale factor 1.4 and divide by 20
20/1.4= about 14.25 or to be exact 14.2857142857
Part a.
The function f(x) = sqrt(x-1) has the domain [1, infinity). We would solve x-1 >= 0 for x to get x >= 1 to ensure that the (x-1) expression is never negative. So the smallest x value we can plug in is x = 1. Recall that applying the square root to a negative number is not defined (assuming you are ignoring complex or imaginary numbers).
--------------------------------------------------------
Part b.
Pick any number you want. Then add on some other number. Let's say we pick 7 as our first number. Then let's say we add on 4. That gets us to 11. Add on 4 again and we jump up to 15. Do it again twice more and you have this sequence
7, 11, 15, 19, 23
which is arithmetic since we increase by the same amount (4) each time. The first term is 7 and the common difference is 4.
--------------------------------------------------------
Part c.
There are lot of options here. All we need to do is ensure that the slopes of each line are different. This will guarantee that the lines are not parallel. Non-parallel lines will always cross each other one time and one time only.
So one system we could have is
the slopes 2 and 6 are different so the system will have exactly one solution.
A ratio equivalent to 3:11 will be multiplying each term by a common term. Eg 3 x 2 : 11 x 2 = 6:22
Answer:
56 pieces of candies at maximum.
Step-by-step explanation: What you want to do is just divide both numbers, giving you 56.2105263158. The decimals will give you the wrong answers, so taking them out, would be the best, and also the decimals aren't divisible to the 19 kids. When you take the decimals out, you should get 56. To prove my point, doing 56 x 19 = 1064 candies, and the 4 other is not able to be split to 19 kids. So there 56 is your answer!
