12345 [234]

Answer: 96 ways

In this case, the freshman must take one class each from Science(6 courses), Humanities(4 courses) and Mathematics( 4 courses).
Then to know how many ways she can arrange you just need to multiply the each course count (it would different if she has to take more than one class).
The calculation would be: 6 x 4 x 4= 96 ways.

The reciprocal of 2/3 is 3/2. If the reciprocal of 4x/5 is 1/20, what is x?

Black_prince [1.1K]

Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation $\frac{4x}{5}=20$ . From there we can solve for x.

Firstly, multiply both sides by 5: $4x=100$

Next, divide both sides by 4 and your answer will be $x=25$

Help. I’m stuck on this one skskksks

VMariaS [17]

I'm pretty sure the answer is: h = 9

Reason:

The question tells us that to complete the equation that represents the relationship between d and h, so for "d", its d = 1, for h, it is 9 per each "days"

from the hours.
