The list of two-digit numbers whose digits add up to 10 would be:
19
28
37
46
55
64
73
82
91
Now the numbers have the same digits only reversed and the difference between the two numbers is 18 - the only pair that fits this description is 46 and 64, thus those are the two numbers
That is your answer and can you please answer mine
Answer:
d = 240 - 44t
Step-by-step explanation:
Distance of the raft to the waterfall
The raft is heading for the waterfall, therefore, the distance between the raft and the waterfall is diminishing.
Waterfall=240 ft from the tunnel
Speed of the raft =44 ft per second
Therefore the equation of a function rule that represent the distance of the raft to the waterfall is:
d = 240 - 44t
Where t=time in seconds
Answer:
$12, 14%
Step-by-step explanation:
Find the amount of discount:
84 - 72 = 12
Find the amount of discount as a percentage
12 / 84 = 0.1428
A+b=-7
ab=-15
a=-7-b
b(-7-b)=-15
a=-7-b
-b^2-7b+15=0
a=-7-b
b^2+7b-15=0
a=-7-b
b=(-7±sqrt(109))/2
1)
a=-7-b
b=(-7+sqrt(109))/2
b=(-7+sqrt(109))/2
a=-7+3.5-sqrt(109)/2
b=(-7+sqrt(109))/2
a=-3.5-sqrt(109)/2
2)
a=-7-b
b=(-7-sqrt(109))/2
b=(-7-sqrt(109))/2
a=-7+3.5+sqrt(109)/2
b=(-7-sqrt(109))/2
a=-3.5+sqrt(109)/2
