Answer:
a = (d-c)/b
Step-by-step explanation:
Let us assume the percentage = x%
Then
75 * x% = 27
75x/100 = 27
3x/4 = 27
3x = 27 * 4
3x = 108
x = 108/3
= 36 percent
So 27 is 36 percent of 75.
I hope the procedure for solving this kind of problems is
absolutely clear to you. You can always use this method for solving similar
problems and hopefully you will not require any help from outside. Just keep a
cool brain while doing the calculation part.
Answer: lock down
Step-by-step explanation: f(x)= 8x2 + 5=21--> f(x)=21
g(x)= -2x5 - 4=-14--> g(x)=-14
The value of the missing length in the image shown using the Pythagoras theorem is x = 65
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.
Let h represent the missing red line. Using Pythagoras:
x² = h² + 25²
h² = x² - 25²
Also:
r² = h² + 144²
r² = x² - 25² + 144²
And:
(144 + 25)² = r² + x²
(144 + 25)² = (x² - 25² + 144²) + x²
x = 65
The value of the missing length in the image shown using the Pythagoras theorem is x = 65
