Answer:
Option C) 195 characters per minute
Step-by-step explanation:
We are given the following in the question:
Jude types 1,170 characters in 6 minutes..
We have to find the typing rate in characters per minute.
Thus can be done in the following manner:
Typing rate =
Thus, Jude speed in characters per minute is
Option C) 195 characters per minute
The decimal moves 2 spaces to the left.
For example:
4 / 100 = 0.04
It is: 180(n-2)
For example, the sum of the interior angles of a triangle is 180 degrees.
The quadrilateral can be cut into two triangle so the sum of the interior angles of a quadrilateral is 180*2=180*(4-2)
The pentagon can be cut into three triangle so the sum of the interior angles of a pentagon is: 180*3=180*(5-2)
The hexagon can be cut into four triangle so the sum of the interior angles of a hexagon is: 180*4=180*(6-2)
Answer:
1). angle 3= 48° [by vertically opposite angle]
2). angle 4 = 132° [by linear pair]
3). angle 5 = 50° [angle 6 and angle 5 are complementary angles]
4). angle 8 =36° [angle 7 and angle 8 are complementary angles]
5). angle 6 = 31° [sum of angle on straight line is 180°]
6). angle 8=33° [sum of angles on straight line is 180°]
7). angle 9=40° [sum of angles of triangle is 180°]
8). angle 3= 30°[angle 9 and 12 are linear pair and 9 is part of the triangle. so, sum of all angle of triangle is 180° ]
9). angle 15= 80° [sum of angles of triangle is 180°]
10). angle 8=35° [sum of angles of triangle is 180°]
11). angle 7=66°[sum of angles of triangle is 180°]
12). angle 14=105° [Sum of angles of triangle is 180°]
13). angle 12=130°[by sum of angle is 180°we'll find 9 then by linear pair angle 12= 130°]
14). angle 8=55° [ angle 14 and 16 are equal by vertically opposite angles and angle 14+angle 8+angle 3=180°]
15). angle 15=90°[first find 7 and 9 by sum of 90°and sum 180° then sum of angles of triangle is180°]
16). angle 16=95°[angle 7 and 8 are complementary angles and angle 1 and 3 are equal by vertically opposite angles now we have our two angles of the triangle so we can find third angle because sum of angle of triangle is 180°]
Answer:
See below.
Step-by-step explanation:
The 'ac' method. here's an example:
Factor x^2 - x - 6.
Compare with ax^2 + bx + c:
a = 1 and c = -6 so ac = -6.
b = -1 so we try -6 = -3 * 2:
x^2 - x - 6
= x^2 - 3x + 2x - 6
Factor by grouping.
= x(x - 3) + 2(x - 3)
= (x + 2)(x - 3).
