As per the problem
The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.
we have been asked to find
Which ratio shows the number of chlorine tablets needed for 42 days?
Since for each 14 days the number of tablets required is 5
So if you multiply the number of days by some number then, we will have to multiply the number of tablets required by the same number.
So When number of days
Then the number of tablets required for 42 days is
Answer:
fraction of geese = 2/5
Step-by-step explanation:
To find the fraction of geese, take the number of geese over the total number of birds
fraction of geese = 2/5
Answer:
n= 26, so the answer would be 'B'.
Step-by-step explanation:
n-8=18
n=18+8
n=26
Answer:
slope (m) = -50 or -50x
Step-by-step Explanation
I'm assuming that the x-axis is divided by 1 minute segments.
The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"
Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute
Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for
Answer:
If log x = 2
x = 100
Step-by-step explanation:
Logarithm always has a base and an index. It can be I many forms.
It can be in base 2, 3, 4, 5, and so on.
It is a property of logarithm that if
logarithm of 'a' to base 'b' equals 'x', we write:
log_b (a) = x
Then,
a = b^x.
Usually, when a logarithm is written without a base, it tells us that it is in base 10. Instead of writing a logarithm of x to base 10,we can just write 'log x', it is sufficient to say that it is in base 10.
It can also be in the form of the Napierian Logarithm, 'ln'.
'ln x' is logarithm to base 'e'.
if ln x = 5
Then
x = e^5.
So,
log x = 2
Means logarithm of 'x' to base 10 equals 2.
x = 10^2
= 100
x = 100
