The slope of a line between 2 points is given by the formula
m = y2 - y1/x2 - x1
m= 22-6/20-12
m= 16/8= 2
slope is 2
Answer:
90 minutes or 1 hour and 30 minutes
Step-by-step explanation:
If 18 minutes is 20% of the work time then you will have to get the 20% to 100% so i divided 20 by 100 and that got me 5 so I put 5 times 18 then that got me 90.
10% of 10 is 10%*10 which is 1 :)
It took him 1 hour and 30 mins .
He needs to go 15 miles. It takes him 1 hour to get 10 miles. After 1 hour has passed he still needs 5 more miles to go. 5 miles is half of 10 so half of 1 hour is 30 mins. 1 hour + 30 mins is 1 hour and 30 mins. (It took him 1 hour 30 mins)
Answer:
180 teachers
Step-by-step explanation:
In this case, we know the value corresponding to 45% of female teachers which is 81, therefore, to find the total it would be:
% teachers #teachers
45 81
100 x
we apply the rule of three:
x = 100 * 81/45
x = 180
which means that there are a total of 180 teachers at Russell High
