Answer:
1/2 of her allowance
Step-by-step explanation:
Multiply 3/4 by 1/2
The equivalent expression of the expression given as 1/x/x+3 is 1/x(x+3)
<h3>How to determine the
equivalent expression?</h3>
The expression is given as:
1/x/x+3
Rewrite as:
1/x/x+3 = (1/x)/x+3
Express the quotient as product
1/x/x+3 = 1/x * 1/x+3
Evaluate the product
1/x/x+3 = 1/x(x+3)
Hence, the equivalent expression of the expression given as 1/x/x+3 is 1/x(x+3)

Step-by-step explanation:
If you know, the sine. You must find the cos ratio, using the Pythagorean trig theorem.
Next, you use the half angle identity for sin

Example.

We must find

First, use the Pythagorean identity





Now use the half angle identiy




So the answer for our example is 1/2
A triangle has 3 sides so, to find the perimeter times 0.75 by 3
You get 2.25
Step-by-step explanation:
Just expand it:
