If you mean fraction,
Tom: 2/3
Sam: 1/4
Now we change the denominator.
Tom: 6/12
Sam: 3/12
6/12 + 3/12 = 9/12
9/12 can be simplified, so 3/4 of the pie was eaten.
4/4 - 3/4 = 1/4
The answer is 1/4.
Answer:
6 hours
Step-by-step explanation:
The equation for this would be
c=3h+12
It costs $3 per hour, and there is a $12 cost no matter how many hours the bike is rented for
We know,c, or the cost is $30, so we can substitute that in
30=3h+12
Solve, by isolating the variable,h
First, subtract 12 on both sides
30=3h+12
18=3h
Divide by 3 on both sides
h=6
So, she rented the bike for 6 hours
<u>44%</u>
Sample space is 36C4
Now, we want to know all of the combinations that have 1 digit in it.
So, we can have one here:
1XXX
X1XX
XX1X
XXX1
But we have 10 different digits to choose from. So, we need to introduce the combination term, nCr, where n is a list of all digits and r is how many we want.
Since we only want one, we will need 10C1 for the number of digits. But we need to choose three lowercases, so it becomes 10C1 × 26C3
Since it's a probability question, we need to divide that by our sample space, 36C4, and our percentage becomes 44%
The value of the differential with respect to x is -xy/x²+ay
<h3>Implicit differentiation</h3>
Given the following function
x²y +ay² = b
We are to differentiate implicitly with respect to x
x²dy/dx + 2xy + 2aydy/dx = 0
(2x²+2ay)dy/dx = -2xy
dy/dx = -xy/x²+ay
Hence the value of the differential with respect to x is -xy/x²+ay
