Answer:
Step-by-step explanation:
First main thing to know is the product and quotient rule of exponents.
Product Rule:
And if this doesn't make sense, you can think of the exponent like this:
and since multiplication is commutative, we can just combine all these x's, and since the total amount on the left is "a", and the right is "b", the total combined x's should be a+b, which can be expressed as:
which can be expressed as an exponent (x^(a+b))
Quotient Rule:
You can use similar reasoning for this, since if you write it out you get
and since you have an x in the numerator and the denominator, you can simply cancel the x's out. In doing this you want to remove the denominator, so you cancel out "b" x's. So there will be (a-b) x's left in the numerator, and a 1 in the denominator, so it's just x^(a-b)
Ok so now let's apply these to solve your question
So let's combine the exponents in the numerator and denominator using the product rule
Now we can divide the 15 by 5, and divide the x^11 by the x^9 using the quotient rule
.5x-20=10 would be the answer for this. Half of a number would be .5x and since you are decreasing by 20, you're subtracting.
Answer:
94%
Step-by-step explanation:
= 60/1000 ×100
= 6%
6% is the value of people did not know how to ride bike.
1000 is equal to 100%
= 100% - 6%
= 94%
94% people know how to ride the bike
Plug in the numbers so it will turn out as 21. Divided by 3(2) . You know that if 2 numbers are close by each other than you are going to multiply so 3 times 2 = 6 , then you do 21 divided by 6 = 3.5
The answer = 3.5
it is 10.63
