Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
Answer:
2/9
Step-by-step explanation:
Since there are 18 total eggs (cracked, white, brown) we can say that the denominator will be 18.
There are 8 white eggs, and when half of those are cracked there will be 4 uncracked and 4 cracked, so 4/18.
Simplify 4/18 to 2/9 and there is your answer.
Answer:74.55 beat per minute
Step-by-step explanation:
Given
Heart beat is 52 beat per minute
i.e.
beat per sec
If heart rate is increases 1.25 % each sec
suppose B is the heart beat at first second therefore heat beat at 2 nd second
![B_2=B+1.25 \% B](https://tex.z-dn.net/?f=B_2%3DB%2B1.25%20%5C%25%20B)
![B_2=B(1+1.25 \% )](https://tex.z-dn.net/?f=B_2%3DB%281%2B1.25%20%5C%25%20%29)
For 3 rd sec
![B_3=B(1+1.25\%)+1.25\%B(1+1.25\%)](https://tex.z-dn.net/?f=B_3%3DB%281%2B1.25%5C%25%29%2B1.25%5C%25B%281%2B1.25%5C%25%29)
![B_3=B(1+1.25\%)^2](https://tex.z-dn.net/?f=B_3%3DB%281%2B1.25%5C%25%29%5E2)
similarly for 3 sec
![B_{30}=B(1+1.25\%)^{29}](https://tex.z-dn.net/?f=B_%7B30%7D%3DB%281%2B1.25%5C%25%29%5E%7B29%7D)
![B_{30}=1.433B](https://tex.z-dn.net/?f=B_%7B30%7D%3D1.433B)
![B_{30}=1.242\ \text{beat per second }](https://tex.z-dn.net/?f=B_%7B30%7D%3D1.242%5C%20%5Ctext%7Bbeat%20per%20second%20%7D)
![B_{30}=74.55\ \text{beat per minute}](https://tex.z-dn.net/?f=B_%7B30%7D%3D74.55%5C%20%5Ctext%7Bbeat%20per%20minute%7D)
Answer: (3, 18)
Step-by-step explanation: Where the lines corss the x does not go over 10 so the only other option is a 3. If you cut the box hori in half in you mind, the top half being 15-20 and the bottom half bring 10-14, then you can see the lines cross on the top half. Meaning it’s at 18 not 12.
