Answer:
We use scientific notation as sometimes numbers are so so big, that it becomes inconvenient for us to write the actual number.
Step-by-step explanation:
For example, if you have 9 billion of something, you wouldn't want to write those 9 zeroes all the time.
When writing in scientific notation we count the number of decimal places to when we have one non-zero integer to the right of the decimal place. We then write that number and multiply it by ten to the number of decimal places you counted earlier.
e.g. 4.8 X 10^7
96 ---> 100%
60 ----> x
x=(60*100%)/96=62.5%
Answer:
B) y=3x
Step-by-step explanation:
2 x 3 = 6
3 x 3 = 9
4 x 3 = 12
You can find y by multiplying the x by 3. The relationship between the x and y is proportional. For example, lets say my x is 20, my y would be 60. 20 x 3 = 60.
If you are still unsure, remember constant of proportionality is k=y/x, so your constant is 3.
Answer:
B=30mm
Step-by-step explanation:
According to the Question,
we have, A parallelogram that has one side(A) 5 millimeters and the other side(C) 10 millimeters. A larger parallelogram has side one side(D) 15 millimeters.
The Enlargement Parallelogram And Original Parallelogram Sides Ratio Remain the same.
Therefore, A/C = D/B
5/10 = 15/B
B=150/5
B=30mm
