Answer:
There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.
There are a lot of differences between these two.
Step-by-step explanation:Firstly, strategy are all in mind and not on paper while written methods are solid proofs that are written on paper. Strategies may or may not work out with respect to the situation, while Written method will always work. They are actually written after testing their reliability. As far as you multiply decimal numbers these will go in vain and you have to use your mind to solve these
Answer:
Step-by-step explanation:
<u>Compounded interest amount formula:</u>
<u>Given</u>:
- P = $956
- r = 6% = 0.06
- t = 12 years
- n = 4 and n = 1
1. <u>Compounded quarterly</u>
- A = 956(1 + 0.06/4)^(4*12) = 956(1.015)^48 = 1953.57
2. <u>Compounded annually</u>
- A = 956(1 + 0.06)^12 = 1923.66
Answer:
35
Step-by-step explanation:
You take 3 times 7 and that's 21. Then 2 times 7 and that's 14. So, 21+14=35
