X=is the number.
50% of x=8
(50/100)x=8
x=(8*100)/50=16

'is' in mathematics means equal
'of' in mathematics means multiplication

Translating 8 is 50% of what number into an equation, we get:

8 = 50% * x

50%, or 50 percent, is nothing but 50 over 100 or 50/100, which is the same as 1/2.

8 = 1/2 * x

Multiply 2 on both sides.

8 * 2 = 1/2 * 2 * x

16 = x

x = 16

8 is 50% of 16.

Which of the following is a valid exclusion for the algebraic fraction:
erastova [34]
We have the following expression:
 (27a ^ 3-1) / (9a ^ 2-6a + 1)
 Rewriting we have:
 (27a ^ 3-1) / (9a ^ 2-6a + 1)
 (27a ^ 3-1) / ((3a-1) * (3a-1))
 We exclude the values that make the denominator zero:
 3a-1 = 0
 a = 1/3
 Answer:
 
a valid exclusion for the algebraic fraction is:
 
c. a ≠ 1/3

Can someone please help me, I don’t understand this
Nady [450]

Answer:

To find the circumference

diameter x 3.14 = circumference

We can undo the multiplication and divide to get the diameter

37.68 /3.14 = 12

diameter / 2= radius

12 / 2 = 6

the radius is 6

radius x radius x pi = area

6 x 6 x 3.14 = 113.04

113.04 is the answer

Hope this helps

Pls help! evaluate the sine of the real number, pls give exact answers
solong [7]

Answer:

 -\frac{\sqrt2}{2} \\  or exact is −0.70710678...

Step-by-step explanation:

Getting the point!

  1. If we look at the unit circle and we find -\frac{3\pi }{4} we see it is in the 3rd quadrant.
  2. We know that all points in the 3rd quadrant have both negative x and negative y values.
  3. We know that all radians with the base of 4 on the unit circle have the points of (\frac{\sqrt{2}}{2} ,\frac{\sqrt{2}}{2})
  4. Because we are in the 3rd quadrant and both x and y are negative we know the point of -\frac{3\pi }{4}  is (-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2})

Finding the sin!

  1. Because we know that sin is asking us for the y value
  2. We can just look at the point and find the y value!
  3. the y value is -\frac{\sqrt2}{2} \\
  4. Because this fraction does not need to be rationalized we are good!
  5. Use a calculator to find the exact value and you get -0.70710678...
  6. The final answer is  -\frac{\sqrt2}{2} \\ or exact is −0.70710678...

What is the value of x?<br><br> Enter your answer in the box
Natalija [7]
In similar triangles the ratio of the corresponding sides is equal.
Therefore in this case; the two triangles are similar;
 hence;
  5 in/ 15 in = 8 in / x
Where  x is the unknown side
 x= (8 × 15)/5
   = 120/5
   = 24 in
Therefore, the value of x is 24 inches
