Answer:
the answer is B
Step-by-step explanation:
Just estimate ex: 5 x 5 would be 25, so sqrt 22 would be just before the 5.
Answer:
1. x = {1.5, 0.2}
2. x = 1
Step-by-step explanation:
Answer:
Paula get 
and Kawai get 
.
Step-by-step explanation:
Given: Paula and Kawai shared 
in the ratio of 
.
To find: How much money did each person get?
Solution:
We have,
Paula and Kawai shared in the ratio of .
So, let Paula get 
and Kawai get 
.
As per the question,
Therefore, Paula get 
, and Kawai get 
.
Hence, Paula get and Kawai get .
The answer is d because 12c=20 = c=65/12 divide by both sides
I suspect you meant
"How many numbers between 1 and 100 (inclusive) are divisible by 10 or 7?"
• Count the multiples of 10:
⌊100/10⌋ = ⌊10⌋ = 10
• Count the multiples of 7:
⌊100/7⌋ ≈ ⌊14.2857⌋ = 14
• Count the multiples of the LCM of 7 and 10. These numbers are coprime, so LCM(7, 10) = 7•10 = 70, and
⌊100/70⌋ ≈ ⌊1.42857⌋ = 1
(where ⌊<em>x</em>⌋ denotes the "floor" of <em>x</em>, meaning the largest integer that is smaller than <em>x</em>)
Then using the inclusion/exclusion principle, there are
10 + 14 - 1 = 23
numbers in the range 1-100 that are divisible by 10 or 7. In other words, add up the multiples of both 10 and 7, then subtract the common multiples, which are multiples of the LCM.
