6 books at $ 8 = (6 * 8) = 48
if he got a discount of 20%, then he paid 80%
0.80(48) = 38.40 <== what he paid
Given:
A figure of right triangle with terminal angle , base u, perpendicular v and hypotenuse r.
To find:
The value of .
Solution:
In a right angle triangle,
Substituting Perpendicular = v and hypotenuse = r in the above formula, we get
The value of is .
Therefore, the correct option is B.
Answer:
I would think that the answer to this is 3 & 1/2 years old.
Step-by-step explanation:
I think don't hold me to that.
The area of d=8in would be A=50.27 squared inches!
The slope of the given line is 5. The correct answer is the second option<em>- slope = 5</em>
<h3>Slope of a line</h3>
From the question, we are to determine the slope of the line in the diagram
Using the formula,
m = (y₂ - y₁)/(x₂ - x₁)
Where m is the slope
To determine the slope of the line, we will pick two points on the line.
Using the points (1, 0) and (0, -5).
Thus,
x₁ = 1
y₁ = 0
x₂ = 0
y₂ = -5
Putting the values into the equation
m = (y₂ - y₁)/(x₂ - x₁)
m = (-5 - 0)/(0 - 1)
m = -5/ -1
m = 5
Hence, the slope of the given line is 5. The correct answer is the second option<em>- slope = 5</em>
