I believe that the answer to this question HAS to be C.I say this because my finding the reciprocal of each option,A,B,and D doesn't match the table,So it's C
Hope this helps.
Answer:
96 + 150 + 2x + x = 360⁰
240 + 3x = 360⁰
3x = 120
x = 40⁰ hope it's help you
Which course is this for? I feel like I may need a little more information, but the simplest explanation I can give given the question is:
<em>f(x)</em> is the value of a function <em>f</em> evaluated at the value <em>x</em>. The formal definition of a function is a particular set of rules that associates a particular value with another. For an analogy: you can think of <em>f </em>as a machine that takes in an input, transforms it according to a certain set of rules, and produces an output. <em />In this analogy, <em>x</em> would be the input and <em>f(x)</em> would be the output.
Answer:
20%
Step-by-step explanation:
We can say that 3/15 students usually go to bed at 9 P.M. We can set up a proportion to solve this problem.
3/15=x/100
We cross multiply to find x
15x=300
Divide both sides by 15
x=20
So 20% of the classmates usually sleep at 9 P.M.
x = dimes
y = quarters
We also know:
Dimes: 0.10
Quarters: 0.25
100 = x + y
So, 0.10x + 0.25y = 100
And, y = 100 - x
Let’s use substitution:
0.10x + 0.25( 100 - x ) = 100
= 0.10x + 25 - 0.25x = 100
= 25 - 100 = 0.25x - 0.10x
= (-75) = 0.15x
x = (-75) divide by 0.15
x = (-500)
