Two integers, a and b have product of -48 what is the greatest possible sum of a and b.

Answers

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.

29 - 7g = 3g + 9 =

PLEASE HELP!

Answers

Answer:

g=2

Step-by-step explanation:

29 - 7g = 3g + 9  

move all the terms to the left, that means subtract it and set it equal to zero

29-7g-(3g+9)=0

Get rid of the parenthesis by grouping like terms together.

-7g-3g-9+29=0

Add all the numbers and variables.

-10g=-20

Divide by -10 on both sides

-10g/-10=-20/-10

Which gives you g=2

If you have lived for a million seconds, how many birthdays have you had?

Answers


A million seconds is not that long.  My next birthday is in  1,296,000  seconds
from now, and I have already lived more than  2.3 billion seconds !

(1,000,000 seconds) x (1 day / 86,400 seconds) =

                 11days 13hours 46minutes 40seconds .

It's possible that you might have one birthday within that length of time,
but it's not guaranteed.  It would have to be the RIGHT million seconds.

If that's been your whole life so far ... you are 1 million seconds old ..,
then you have not had your first birthday yet.
You will only be 11.57 days old. 
Arguably, however old we are, we only have one 'birthday' which is the day of our birth. What is referred to as our first birthday is actually the the first anniversary of our birth and subsequent ones are the relevant anniversaries our birth.

You have 2 triangles and 3 rectangles. 
Start with a triangle:
area is base side * height / 2 ->  4 * 3 / 2 = 6
The other triangle has the same area: 6

First rectangle: side * other side -> 7 * 5 = 35
Second rectangle: 7 * 4 = 28
Third rectangle: 7 * 3 = 21

Now simply add all this together: 6+6+35+28+21 = 96
