Answer:
√9 is ____rational______ number *
Step-by-step explanation:
√9 = √(3×3)=3 which is rational
Answer:
if that is supposed be a decimal then round tenths place which is still six
Step-by-step explanation:
34% written in decimal form is .34 (by moving the decimal 2 places left).
.34 written as a fraction is 34/100. Reduce the fraction by dividing numerator and denominator by 2 to get 17/50.
The ratio is 17:50
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.

<em>Additional comment</em>
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.
To reflect over the y axis, the formula is (-x, y). For W, which currently is (-6, -4), the -6 becomes -(-6), which is the same as 6, so the answer is (6, -4).
