Answer:
The answer to this question is option B which is $42.55.
The above statement shows that Muriel has kept track of her income and also expenses for the week in the spreadsheet.
By using the spreadsheet, you can easily calculate the restaurant bill of Muriel. The Muriel’s restaurant bill is calculated as $42.55
Answer:
$5
Step-by-step explanation:
so 4 dollars is the discount
100-20=80 so
4 dollars =80%
1 dollar=20%
80+20=100
4+1=5
original price=$5
By dropping a perpendicular from the top of the isosceles triangle to the base and using the Pythagorean Theorem we quickly determine that the height of the triangle is 4.
Therefore the area of the isosceles triangle is
6•4/2=12
However, we can split the isosceles triangle into three separate triangles indicated by the red lines in the diagram below. Because the radius always meets a tangent at a right angle the area of each triangle will be the length of the side multiplied by the radius of the circle. So the total area of the isosceles triangle is given by
6r/2+2•5r/2=8r=12
8r=12
r=12/8
r=3/2
Answer:
The slope of FG is -1
Step-by-step explanation:
Given
Square EFGH
EF: 
Required
Determine the slope of FG
First, we calculate the slope of EF
Make y the subject
The general equation has the form: 
Where
Compare to
<em>From the name of the square EFGH, we can conclude that EF and FG are perpendicular</em>
<em />
The relationship between perpendicular lines is:
Where
-- Slope of EF
and
m2 = slope of FG
Substitute 1 for m1 in
<em>Hence, the slope of FG is -1</em>
