Subtract:<br> 7' 5" – 2' 8" =
yKpoI14uk [10]

Answer:

4'9"

Method 1:

First, convert both numbers into inches. Remember that 1' = 12", and the rest is like a remainder.

7'5" = (7*12)+5 = 84+5 = 89

2'8" = (2*12)+8 = 24+8 = 32

Next, subtract the two numbers.

89 - 32 = ?

89 - 32 = 57

There's your answer! You can change it back into feet by dividing it by 12.

57 / 12 = 4.75 = 4'9"

Method 2:

Another way of solving this problem is to borrow from the "feet" place.

7'5" - 2'8"

You can't take 8 away from 5, so you borrow from the "feet" place. Remember that unlike normal borrowing, you need to add 12 instead of adding 10.

6'17" - 2'8" = 4'9"

Whichever method you choose, you should get the same answer!

What property does the following expression demonstrate? -10+6=6+(-10)
rusak2 [61]

<u>ANSWER</u>

Commutative property of addition.

<u>EXPLANATION</u>

Let a,b be real numbers. The commutative property of addition states that,

a + b = b + a

If we let a=-10 and b=6, then

-10+6=6+(-10)

Therefore the given expression demonstrates the commutative property of addition.

The commutative property of addition tells us that, the order in which we add two real numbers does not affect the result.

A ball is thrown from an initial height of 6 feet with an initial upward velocity of 23ft/s . The ball's height h (in feet) afte
Diano4ka-milaya [45]
There's a lot of extra information here. All you are really concerned with is solving the polynomial for roots. You want t when h = 14. So let's do it:

14 = 6+23t-16t^2
8=23t-16t^2

Rearranging to make it simpler to put into a quadratic form:
0 = -16t^2+23t-8

Now, let's plug it into the quadratic equation:
\frac{-23+ \sqrt{(23)^2-4(-16)(-8)} }{2(-16)}
and
\frac{-23- \sqrt{(23)^2-4(-16)(-8)} }{2(-16)}

Solving the quadratic gives us:
0.5899 and 0.8476

So, your answer is: h = 14 when t = 0.5899 or t = 0.8476
