Answer:
To start off, this fraction needs to be rationalized; you can't have a radical in the denominator. So, you multiply both the numerator & denominator by the same number (so as to not mess up the proportion of numerator:denominator; it's like multiplying by 1) & get the radical out of the denominator. What number would that be? sqrt5.
So we have (sqrt6/sqrt5)•(sqrt5/sqrt5).
To simplify that, we get (sqrt6•sqrt5)/(sqrt5•sqrt5).
This can be rewritten as:
sqrt(6•5)/sqrt(5•5)
= sqrt30/sqrt25
Now, sqrt25 = 5, so that problem is solved as such:
sqrt30/5
I'm thinking sqrt30 can't be simplified any further. If it can, do so.
Hope this helps!
Step-by-step explanation:
x=t-yz
x = Amount down
y = Money each month
z = Number of months
t = Total price
Rewrite the formula to solve for the amount of money Jeremy must pay each month.
Answer:
Step-by-step explanation:
Given: A formula that describes this scenario:
where, x = Amount down
y = Money each month
z = Number of months
t = Total price
To solve the formula for the amount of money Jeremy must pay each month i.e. y, first subtract t on both sides of the equation, we get,
Now, divide z on both sides, we get
The correct answer is:
Explanation:
We want to solve for the amount of money he pays each month. This is represented by y in the equation. This means we want to isolate y in the equation:
x = t - yz
We first want to subtract t from each side:
x - t = t - yz - t
x - t = -yz
Now we want to cancel the negative sign and z. We can isolate both of these at the same time; divide both sides by -z:
We can divide the numerator by the negative sign; this gives us
WKOD 13%
WANR 22%
WCLM 24%
WWCN 41%
write a ratio to express the number of people who preferred WANR to those who preferred WCLM
A. 11 : 12
B. 23 : 100
C. 46 : 100
D. 3 : 50
Answer:
Option A is right
Step-by-step explanation:
The graph represents the results of a survey where 400 people were asked to identify the preferred TV channcel.
Of those the data collected gave
WKOD 13%
WANR 22%
WCLM 24%
WWCN 41%
Ratio of people who preferred WANR to those who preferred WCLM
= 22%/24%
=11:12
Hence answer is 11:12
