How to work out math problem %of 50 shirts is 35 shirts
2 answers:
"of' is multiplication.
"is" is equal.
So x% of 50 is 35 could be written as
x%
50 = 35
The first step is to divide by 50 on both sides.
x% times 50 divided by 50 is x%.
35 divided by 50 is .7
So x% = .7.
The next step is to get rid of the percent sign to find the value of x (our answer). To do this, we multiply by 100 on both sides.
x% times 100 is x.
.7 times 100 is 70%.
So x = 70%.
The answer:
70% of 50 shirts is 35 shirts.
"is" is equal.
So x% of 50 is 35 could be written as

The equation of the hyperbola is :
The center of a hyperbola is located at the origin that means at (0, 0) and one of the focus is at (-50, 0)
As both center and the focus are lying on the x-axis, so the hyperbola is a horizontal hyperbola and the standard equation of horizontal hyperbola when center is at origin:
The distance from center to focus is 'c' and here focus is at (-50,0)
So, c= 50
Now if the distance from center to the directrix line is 'd', then
Here the directrix line is given as : x= 2304/50
Thus,
⇒
⇒ a² = 2304
⇒ a = √2304 = 48
For hyperbola, b² = c² - a²
⇒ b² = 50² - 48² (By plugging c=50 and a = 48)
⇒ b² = 2500 - 2304
⇒ b² = 196
⇒ b = √196 = 14
So, the equation of the hyperbola is :
