2/10 because 0.7/7 is equal to one tenth, so 1.4/7 is equal to 2/10
Answer:
90:180, 135:270, 180:360
Step-by-step explanation:
Answer:
Step-by-step explanation:
Suppose that the side length is s. Imagine that one side is level. Draw a vertical line through the top vertex perpendicular to the base (level side). Label this vertical line "h." Then h and s are related as follows:
√3 h
sin 60 degrees = ------- = --------
2 s
s√3
and so h = the height of the triangle = -----------
2
The area of this triangle is (1/2)(base)(height), which here is:
(1/2)(s/2)( s√3 /2), or
(s^2)√3
A = ---------------
8
The angle is 90° degrees.
Answer:
C. 300=60+30w
Step-by-step explanation:
Given:
Price of television-$300
Initial Payment-$60
Weekly payments-$30
Let weekly payments be w:
The initial payment plus the weekly installments should be equivalent to the television price:
The number of weekly payments is 8 weeks and the equation to solve for w is
300=60+30w
