Answer:
26.37
Step-by-step explanation:
To find the % of something simply turn 5.5% to a decimal (.055) then times it by the number you want .055 * 25 = 1.37 so add the tax too your total and youll get <u>26.37</u>
<h3>(a) The square</h3>
For all rectangles, the area is the length multiplied by the height. For squares (a special type of rectangle), the length and height are the same, so you just use 
, where 
is the side length.
<h3>(b) The circle</h3>
The formula for the area of the circle is 
, where 
is pi, a constant, and 
is the radius of the circle, or the length from the center point to the edge.
We're given the side length of the square, which is the same as the diameter of the circle (length from edge to edge going through the center point). Divide the diameter by 
to get the radius of 
kilometers.
<h3>(c) The blue section</h3>
The area of the blue section is simply the area of the square minus the area of the circle since we just want what's left over.
You can keep the answer exact (the boxed expression) or use the approximate value of 54.9, depending on the instructions for the assignment.
Answers:
- Angle Y = 75 degrees
- Angle YVX = 39 degrees
- x = 4
=====================================================
Explanations:
For any parallelogram, the opposite angles are always congruent. The upper left corner shows angle W = 75 degrees. The angle opposite this is angle Y in the bottom right corner, so angle Y must also be 75 degrees.
-------------
The opposite sides of a parallelogram are parallel. Because WX is parallel to VY, this means the alternate interior angles WXV and YVX are the same measure. The diagram shows angle WXV = 39. Therefore, angle YVX is also 39 degrees.
--------------
The opposite sides of a parallelogram are also the same length (in addition to being parallel). The opposite sides WV = 3x and XY = 12 are the same length, meaning....
WV = XY
3x = 12
x = 12/3
x = 4
Answer:
∠ PQR = 143°
Step-by-step explanation:
∠ PQR and ∠ SQR are adjacent angles and are supplementary, thus
∠ PQR = 180° - 37° = 143°
