Answer:
To find the inverse equation, switch the x and y variables then solve for y.
Original equation: .
y = 100 - x²
Inverse:
x = 100 - y²
y² = 100 - x
y = + √(100 - x) or the first option
Step-by-step explanation:
Answer:
To find the LCM you must find all factors of the numbers, and then multiply all the factors together including the ones that are not shared among the numbers.
For example,
Factors of 10: 2×5
Factors of 30: 2×3×5
LCM of 10 and 30: 2×3×5 = 30
However do note not to multiply a factor more than once if it is shared among two numbers.
<u>Answer:
</u>
An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs
<u>Solution:
</u>
Let x = time it will take to fill the pool
= work rate of inlet pipe
= work rate of drain pipe
Using the formulae
Volume of flow=work rate time
Let us assume complete time of pool to fill = 1
Remaining fraction of pool to be filled =
Time it will take to fill the pool = 748 hrs
Answer: 1/2
Explanation: 5 out of 10 numbers are odd and the probability for picking it would be 5/10 and reduced is 1/2
Answer:
Step-by-step explanation:
1/3p=34h
p=102h
h=p/102
h=1/102p
Hence she can write 1/102 part of the paper in an hour
