<u>Given</u>:
The radius of the circle is 10 cm
The central angle of the circle is (360 - 90)° = 270°
We need to determine the area of the composite figure.
<u>Area of the composite figure:</u>
The area of the figure can be determined using the area of the sector formula.
Thus, we have;
Substituting and in the above formula, we get;
Simplifying, we get;
Multiplying, we get;
Dividing the terms, we get;
Thus, the area of the composite figure is 235.5 cm²
Hence, Option C is the correct answer.
Could be A Hexagon, Hoped i help.
The problem should be 7.5=3k. So that means that you have to divide both sides by 3. Once you do that you should get 2.5 as your answer.
Given:
The length of a rectangle is 3 inches less than three times its width.
The perimeter of the rectangle is 34 inches.
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then, the length of a rectangle is 3 inches less than three times its width.
Length of the rectangle = 3x-3
Now, perimeter of the rectangle is
The perimeter of the rectangle is 34 inches.
Divide both sides by 8.
The value of x is 5. So, width of the rectangle is 5 inches.
Therefore, the length of the rectangle is 12 inches and the width of the rectangle is 5 inches.
Answer:
y > 4x - 2
Step-by-step explanation:
The basic format of a line in slope-intercept form is,
This format undergoes no change when one implements it for the use of a two-variable inequality.
The parameter (m) represents the slope of a line, this can be found by using the formula (). Traditionally, one would use a formula to find the slope of a line that is the following, (). However, in the given situation, one can simply count the number of boxes from one point with respect to the x-axis to another, and thus get (4).
The parameter (b) represents the point in which the graph intersects the y-axis, one can see that this point is (-2).
Since the line is dotted, one would only use the greater than symbol, not the greater than or equal-too-symbol.
Finally, since the area above the line is shaded, therefore one knows that it is (y) is greater than.
