Answer:

2000 cm^2/min

Step-by-step explanation:

According to the given question,

12 m^2/h = ? cm^2/min

We know,

1 h = 60 min and 1 m = 100 cm

So, by putting the values we get

  • 12 m^2/h = 12 × (100)^2/60

  • 12 m^2/h = 12×10000/60

  • 12 m^2/h = 2000 cm^2/min

Thus the answer of the given question is 2000 cm^2/min .

Find the equation of the line passing through (1,4) and (-2,-1).
wel

Answer:

y=5/3x+7/3

Step-by-step explanation:

Here are the points: (1,4) and (-2, -1)

let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope)

label the points:

x1=1

y1=4

x2=-2

y2=-1

now subsitute into the equation

m=(-1-4)/(-2-1)

m=-5/-3

m=5/3

the slope of the line 5/3

Here's the equation so far:

y=5/3x+b (b is a place holder)

we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>

let's use (1,4) as an example

4=5/3(1)+b

4=5/3+b

subtract 5/3 from both sides

7/3=b

Now, put it all together:

y=5/3x+7/3

Hope this helps!

Two integers, a and b have product of -48 what is the greatest possible sum of a and b.
dusya [7]
The factors of 48 are:
1 x 48
2 x 24
3 x 16
4 x 12
6 x 8
and visa versa:   48 x 1  etc.

To make the product negative, one of the factors has to be positive and one has to be negative.  To find the greatest sum, make the bigger number the positive factor and the smaller number the negative factor.  So, -1 x 48 = -48 and the sum of -1 + 48 = 47 which would be the greatest possible sum.
