Answer:
Step-by-step explanation:
3 hours is equivalent to 180 minutes (found by multiplying the number of hours, 3, by the number of minutes in an hour, 60).
Therefore, the fraction of 3 hours that 25 minutes represents is , which can further be simplified to .
Which one is problem number 4?
Answer:
Step-by-step explanation:
Given the equation
4x+12y=72
The equation of a line can written as
y=mx+c
Where m is the slope
And c is the intercept on y axis
Then, we need to write the equation given in the form of equation of a line (y=mx+c), by making y subject of the formula
4x+12y=72
12y=-4x+72
Divide through by 12
y=-4x/12 + 72/12
y=-⅓x+6
Then, comparing with equation of a line shows that
m=-⅓ and c=6
So we need to get another linen that is perpendicular to this line and passes through the point (-9,6)
The slope of the line perpendicular to another line is given as
m1=-1/m2
Then, m1=-1÷-⅓
Then, the slope of the perpendicular line is 3
Then, m=3
So apply this to equation of the line
y=mx+c
Then, y=3x+c
So to know c, we will insert the point given(-9,6), x=-9 and y=6
y=3x+c
6=3(-9)+c
6=-27+c
Then, c=6+27
c=33
Then, the equation of line becomes
y=3x+33
Answer: A
Step-by-step explanation:
3000 impressions
A CTR 2% conversion 25%
2% of 3000 = 2/100 . 3000 = 60 clicks
25% of 60 = 25/100 . 60 = 15
B CTR 4% conversion 10%
4% of 3000 = 4/100 . 3000 = 120 clicks
10% of 60 = 10/100 . 120 = 12
This way, A converted more than B
