Answer:
Step-by-step explanation:
Let's break it down. There is..
-----------------------------------------------------
A square root of a number: (assuming "the number" is ).
And they say that 9 is less than that, so we subtract 9 from , which gives us .
I hope that helps! :)
Answer:
7
Step-by-step explanation:
1 hour = 118 guests
826 / 118 = 7 hours
Answer: Nancy needs 26 minutes to driving to work.
Explanation:
Since we have given that
Time taken in eating breakfast = 10 minutes
Time taken in making her bed = 5 minutes
Let the total time taken by her in doing routine activities be x
Time taken in getting dressed is given by
So, According to question,
Now, we need to find the time taken in driving to work which is given by
Hence, Nancy needs 26 minutes to driving to work.
Answer:
The table not represent a proportional relationship
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
we have
For x=3, y=17
Find the value of k
----->
For x=5, y=27
Find the value of k
----->
For x=8, y=42
Find the value of k
----->
For x=9, y=47
Find the value of k
----->
The values of k are different
therefore
The table not represent a proportional relationship
<u><em>Find the slope of the line</em></u>
(3,17) and (9,47)
m=(47-17)/(9-3)=30/6=5
Find the equation of the line with m=5 and point (3,17)
y-y1=m(x-x1)
substitute
y-17=5(x-3)
y=5x-15+17
y=5x+2
This is the linear equation that represent the points in the table, but this equation not represent a proportional relationship (The line not passes through the origin)
