Answer:
x= 6.25
Step-by-step explanation:
The hypotenuse of triangle JKL is taken as 96, in the similar way the hypotenuse of triangle JTU is 36. So x can be found by first finding the value of JU, using the Pythagoras theorem.
[tex]a^{2} = b^{2} + c^{2}[/tex]
In this shape the formula will be:
[tex]TU^{2} = JT^{2} + JU^{2}[/tex]
Substitute the given values in the shape into the formula.
TU = 34
JT = 27
TU = Lets take 'y'
[tex]34^{2} = 27^{2} + y^{2}[/tex]
1156 = 729 + [tex]y^{2}[/tex]
[tex]y^{2}[/tex] = 1156 - 729
[tex]y^{2}[/tex] = 427
y = [tex]\sqrt{427}[/tex] = 20.7 ( rounded to 1 decimal place) = 21 (rounded to whole number).
So the original value of JU is '21', but we have to find the value of 'x'. So the expression '-4 + 4x' is equal to 21. This can be written as:
-4 + 4x = 21
4x = 21 + 4
4x = 25
∴ x = [tex]\frac{25}{4}[/tex] = 6.25
x= 6.25

what is the decimal multiplier to increase by 75%
Answers
Answer:
1.75
Step-by-step explanation:
Let the number to be increased be x
If x is to be increased by 75% then the result after the increase T may be expressed as
T = x + 75% * x
T = x + 0.75x
T = 1.75x
As such when x is increased by 75%, the result is the product of x and 1.75 (the multiplier).

Answer:
f = 2Step-by-step explanation:
f(x) = x2 ... when 'x' is equal to 5
So...
1.) Plug in 5 for the variable 'x'
f(5) = (5) * (2)
2.) Simplify both sides of the equation
5f = 10
3.) Divide both sides by 5
5f /5 = 10/5
f = 2
