Answer:
a repeating decimal can be written as a fraction using algebraic methods, so any repeating decimal is a rational number.
u = 10.4 and v = 12
Solution:
In the given 2 sides of a triangle are 60°, 60°.
Sum of all the angles of a triangle = 180°
60° + 60° + third angle = 180°
⇒ third angle = 180° – 60° – 60°
⇒ third angle = 60°
All angles are equal, therefore the given triangle is an equilateral triangle.
⇒ All sides are equal in length.
⇒ v = 12
The line drawn from the top angle divides the triangle into two equal parts
and the line is perpendicular.
12 ÷ 2 = 6
Using Pythagoras theorem,
⇒
⇒
⇒
⇒
⇒ u = 10.4
Hence, u = 10.4 and v = 12.
Answer:
C
Step-by-step explanation:
A can be from 2- 9 ( 8 digits)
B can be 0 to 9 (10 digits)
C can be 0 to 9 (10 digits)
Each of the X's can be 0 to 9 (10 digits)
To get the number of possibilities, we multiply them to get:
8 * 10 * 10 * 10 * 10 * 10 * 10 = 8,000,000
But now, 1 number (867-5309) is restricted, so the number of possibilities decrease by 1:
8,000,000 - 1= 7, 999, 999
Correct answer is C
Answer:
y=7/3x+8
Step-by-step explanation:
You have to start at the 3and rise all the way to the 8 which is 7 and then run which is 3 so the slope mx is 7/3x. To find b which is the y intercept find the point where the line hits the y-axis.
