Answer:
b. never
Explanation:
A fraction is always in the form p/q, where q is not 0; or can be converted in that form (in case of mixed fraction).
A number is said to be irrational, if it cannot be expressed in the form p/q, where q is not 0.
Answer:
$49
Step-by-step explanation:
<u><em>Method 1</em></u><u><em>:</em></u>
100% - 65% = 35%
y · 100 = 35 · 140
100y = 4900
100y ÷ 100 = 4900 ÷ 100
y = 49
<u><em>Method 2</em></u><u><em>:</em></u>
y · 100 = 65 · 140
100y = 9100
100y ÷ 100 = 9100 ÷ 100
y = 91
$140 - $91 = $49
Answer:
D
Step-by-step explanation:
I like to do it by adding 4 and 3 to get 7. then divide 35 by 7. that would be 5. take 5*4 to get 20 boys and 5*3 to get 15 girls.
Answer:
Step-by-step explanation:
The inverse is found by interchanging the x and y values and solve the result for y.
I will use y for f(x)
y = 4x^2
Inverse
x = 4y^2 Divide by 4
x/4 = 4y^2 /4
x/4 = y^2 Take the square root of both sides.
sqrt(x/4) = sqrt(y^2)
y = sqrt(x/4)
g(x) = sqrt(x/4) If you have a very fussy teacher, the inverse function could be written as
g(x) = +/- sqrt(x)/2
I expect that if the question is computer marked, I would try g(x) = sqrt(x)/2 first.
