Just find 80% of 60 players: 0.80(60 players) = 48 players are rt. handed.
Well to find out you need to cross multiply, 7 x 6= 42 so thats the denominator now 7x4= 28 so 4/6=28/42, 6x5=30 so 5/7=30/42, which one is bigger? 30/42 a.k.a 5/7.
Answer:
4 hours and 45 minutes
Step-by-step explanation:
The only thing you have to do is subtract 8 by 3:15 which is 4:45. 4:45 means that it its 4 hours and 45 minutes.
Hope this helps
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
