Answer:
1) 3/4
2) 15 days
Step-by-step explanation:
A has completed 3/12 = 1/4 of the work
3/4 of the work is left to be done
B can do the work in 20 days.
Since 3/4 of the work is left,
He needs (3/4)×20 = 15 days to complete the remaining work
Answer:
A and C
Step-by-step explanation:
Perpendicular lines have reciprocal and opposite slopes.
First slope =3,
Second = -3
Third slope = -1/3 (which is opposite and reciprocal to the first)
Last slope = -3
Answer:
(–10, –2), (6, 6)
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
<u><em>Verify each case</em></u>
case 1) (5, –4), (–2, 1)
substitute in the formula
----> the slope is negative
case 2) (6, –10), (2, 10)
substitute in the formula
----> the slope is negative
case 3) (–10, –2), (6, 6)
substitute in the formula
----> the slope is positive
case 4) (5, –1), (–6, 6)
substitute in the formula
----> the slope is negative
It’s 2/10 there you go since there’s no 0 infort of the 2 it’s always a 10
