Answer:
50000 m
Step-by-step explanation:
50km/h
It means that 1 hour can travelling 50 km
1km=1000m
50km=50000m
So 1hour can travel 50000m
25 divided by 23 will not come out as a whole number. 23 goes into 25 1 time so the answer would be 1..... But I guess the answer would be A since that's the closest answer choice.
Answer:
System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}
Answer:
(a) No; rainfall amounts are positive
Step-by-step explanation:
Rainfall amounts are measured using a gauge that reports the amount as zero when the gauge is empty. Any rainfall adds to the amount in the gauge, so is reported as a positive number. There is no way to remove more rainfall than is in the gauge, so there is no way to have a negative rainfall amount
A prediction of a negative rainfall amount makes no sense, because you can't have a negative amount of rainfall.
