- 3 = xy + z
xy + z = - 3
subtract z from both sides:
xy +z - z = -3 - z
yx = - 3 - z
Divide both sides by y :
yx / y = - 3 - z / y
x = -3-z / y
y ≠ 0
hope this helps!
Answer:
X=64%
Step-by-step explanation:
The percentage of Cooper in the coin is 64%
How do you come to this conclusion?
252525--100%
161616--X%
Now you can use the cross rule: X=(161616x100)/252525
Check it out now X=64%
Answer:
x = 24.1
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan 15 = x/90
90 tan 15 =x
x=24.11542
To the nearest tenth
x = 24.1
The number of minutes it will take 5 machines to make 15 widgets is 90 minutes
Given that :
The time taken to make a widget is directly proportional to the number of widgets made and inversely proportional to the number of machines utilized.
Using the variation protocol defined :
Let :
n = number of widgets made
n = number of widgets made m = number of machines used
n = number of widgets made m = number of machines used t = time taken
Hence, from joint variation :
t α n α 1/m
t = kn/m
Where k = constant of proportionality :
Solving for k
When t = 10, n = 5, m = 15
10 = (k × 5) / 15
15 × 10 = 5k
150 = 5k
k = 150 / 5
k = 30
Equation becomes :
t = 30n/m
Solve for t ;
When m = 5 ; n = 15
t = (30 × 15) / 5
5t = 450
t = 450 / 5
t = 90
Hence, it will take 90 minutes.
