Answer:
80%
Step-by-step explanation:
24 devided by 30 = 0.8
0.8 times 100 = 80%
Answer:
The equation of the line is x = 2
Step-by-step explanation:
* It is a coordinate geometry problem.
We need to find the equation of a line with undefined slope.
* The slope is undefined
The line passing through point (2 , 5)
* The rule to find the slope is 
The slope is undefined if 
That means the line passing through points have same x-coordinate
That means the line is vertical
* ∵ The line passing through point (2 , 5)
∵ The slope of the line is undefined
∴ All the points on the line have x-coordinate = 2
∴ The equation of the line is ⇒ x = 2
* The answer is x=2
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°.
Answer:
C. 8x+80.
Step-by-step explanation:
To make this a simple expression, we need to distribute the 8 into x+10. We do this by multiplication. 8*x=8x. 8*10=80. Our new equation is 8x+80.
Answer:
7.6 cm²
Step-by-step explanation:
Area of rectangle= l x w
3 x 4 = 12 cm
Area of circle= πr²
π x 2.5²= 19.625
Area of shaded= Area of circle - area of rec
19.625- 12= 7.625 cm²
≈7.6
