(1/2) / (1/4) = 1 / x......1/2 wall to 1/4 hr = 1 whole wall to x hrs
cross multiply
(1/2)(x) = (1/4)(1)
1/2x = 1/4
x = 1/4 * 2
x = 2/4 reduces to 1/2....so it will take 1/2 hr (or 30 minutes) to paint the whole wall.
When the exponent is negative, you have to make the number a fraction(1 over the number).
For example:
This gets rid of the negative, but it leaves the exponent
When an exponent is a fraction, it is the square root.
For example:
![x^{\frac{1}{3}} = \sqrt[3]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%20%3D%20%20%5Csqrt%5B3%5D%7Bx%7D)
![x^{\frac{1}{4}}=\sqrt[4]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7Bx%7D)
So...
He will need 6 tenth size strips because if you put 3/5 vertically with another fraction beside of it that had the numerator blank and the bottom 10. You do this because Jeff uses fifth size strips so 5 represents the strips and you need tenth size strips so you find our numerator for the tenth size strips. You find out how many times 5 can go into 10 or 5 times what equals 10 and it's 2. So whatever you do to the bottom you do to the top. You times 5 by 2 at the bottom and get 10 for the tenth size strips and 3 times 2 at the top yoi get 6 and that is 6/10 is your answer
Answer:
he can make 8 piles before he runs out and has 2 cards leftover
Step-by-step explanation:
False however a one to one function has to be represented by a straight line the way to test a function is the vertical line test
