49
Because 7x7 is 49 & 4+9=13
Answer:
4•8 feet
Step-by-step explanation:
Distance= first floor × second ÷ escalator
Distance= 12feet × 12feet ÷ 30 feet
= 12×12÷30
= 4•8 feet
Answer:
The Answer is 22.5
Step-by-step explanation:
because 3/4 is 45 minutes.'
and 3/8 is 22.5 minutes.
45-22.5=22.5 minutes different.
Answer:
5y - 6x = 8 or y = 6x/5 + 8/5
Step-by-step explanation:
let M1= gradient of line AB and M2= gradient of the second line
When two lines are perpendicular, the product of their gradients is -1
i.e, M1M2= -1
M2= -1/M1
A(2,9) and B(8,4)
gradient= (y2-y1)/(x2-x1)
M1= (4-9)/(8-2)
= -5/6
M2= -1÷ -5/6
-1 × -6/5= 6/5
Equation of the line passing through C(-3,-2)
[y-(-2)]/[x-(-3)= 6/5
(y+2)/(x+3)= 6/5
5(y+2)= 6(x+3)
5y+10=6x+18
5y= 6x + 8
y= 6x/5 + 8/5
