10% left handed
90%(9/10) right handed
1:9
Answer:
first off here are the things you need to know:
She parked her car 4 levels below the street
so let's make that 4
and he doctor's office is at the fifth level of the building which makes it 5
so; 4+5=9 meaning she ride the elevator 9 levels
The function is modulus cause the range of function consists of non-negative numbers with the same magnitude.so the second one is the answer
Answer:
6 gallons
Step-by-step explanation:
You can find this using the ration method.
If, 8 gallons : 192 miles
x gallons : 144 miles
We must find the value of x, which is the number of gallons used to travel 144 miles.
Cross multiply the ratios.
192 x = 8 × 144
192 x = 1152
x = 1152 ÷ 192
x = 6
∴ It takes 6 gallons to travel 144 miles.
Hi!
Square roots where the things under the root are multiplied (for example 
) can be split up into 
.
That's what I'm going to do in this case. I'm going to split ![\sqrt[3]{125x^{12}}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B125x%5E%7B12%7D%7D%20%20%20)
into ![\sqrt[3]{125} * \sqrt[3]{x^{12}}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B125%7D%20%2A%20%5Csqrt%5B3%5D%7Bx%5E%7B12%7D%7D%20%20%20%20)
Now, the cube root of 125 is 5, because 5 * 5 * 5 = 125, and that is the definition of a cube root. (What multiplied 3 times by itself is equal to what's under the root)
Now to look at what the cube root of 
is.
A cube root can be rewritten as 
, same as a square root can be rewritten to 
.
So if you take the cube root of x^12, you can change it to:
If you have a case like this, then you can multiply the two powers (in this case 12 and 1/3) to simplify it. 12 * 1/3 = 4, so you get x^4.
Now putting the two together, you get:
5
as your answer.
Hope this helped!
