Answer:
Betty = $600
Step-by-step explanation:
3/4 of Alice's salary is the same as 1/2 of Betty's salary
(3/4)a = (1/2)b
multiply both sides by 2
(3/2)a = b
Alice earns $200 less than Betty
b - a = 200
Substitute for b
(3/2)a - a = 200
(1/2)a = 200
multiply both sides by 2
a = 400
b = (3/2)400
b = 600
The last one since there are no solutions
Answer:
The ratio that compares the championships won by Australia to the total number won by the United States is equal to 
Step-by-step explanation:
Observing the graph
we know that
The championships won by Australia are 6
The championships won by the United States are 15
To find out the ratio, divide the championships won by Australia by the total number won by the United States.
so

Simplify
Divide by 3 boths (numerator and denominator)

Convert to percentage

that means
For every 2 championships won by Australia the United States won 5
or
The championships won by Australia are 40% of the championships won by the United States
Answer:
<h2>$99.84</h2>
Step-by-step explanation:
Step one:
given data
we are told that before tax the bill is pretax= $78
the tax is 8%
and he left 20% of the pretax for the attendant.
Step two:
let us find the amount he paid for eating with tax
=8/100*78
=0.08*78
=$6.24
with tax the meal cost is
= 78+6.24
=$84.24
let us solve for the tip he left (note: it is 20% of the pretax)
=20/100*78
=0.2*100
=$15.6
the tip is $15.6
Step three:
<u>the total amount he paid after eating plus tax and tip is </u>
78+6.24+15.6
=$99.84
area of rectangle= 8*13=104m^2
base of the Triangle= 13 -(4+4)=5
area of Triangle = 5*6/2=15m^2
area of shaded shape =104-15= 89m^2
