Answer:
the required ratio is 7 : 232
Step-by-step explanation:
by solving both sides we get ,
=》7 - ( 7-7 ) : 8 × 29
=》7 - 0 : 232
=》 7 : 232
it's the required ratio ,
i hope you got it .
3x-4y=10
or,4y=3x-10
or,y=(3x-10)/4
so,y=3/4 x-5/2
Write and solve an equation of ratios:
6 inches 1 inch
-------------- = ------------
60 inches x
Cross-multiplying, 6x = 60, so x = 10 inches (answer)
Step-by-step explanation:
This event that's taking place is happening twice. The event is the mail getting delivered. It's happening two times. Luckily, you already know the probability of it happening once. Because it happens twice, you just square it. (0.9)^2. 0.81 chance of it happening in two consecutive days.
Answer:
(2)
Step-by-step explanation:
Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)
Thus,
=> -x³ - 9 = y
=> - y - 9 = x³
=> (-y - 9)^(1/3) = x
=> f(y) = x
Inverse is (-y-9)^(1/3)
Replacing the variable, inverse is (-x-9)^(1/3)
