Answer:
4.50+.75d=7.50+.65d
Step-by-step explanation:
Y=4.50+.75d equation 1
y=7.50+.65d equation 2
4.50+.75d=7.50+.65d sub value of y in equation 2 into equation 1
.10d=3.00 simplify equation
d=30
check answer by subbing 30 for d into each equation.
y=4.50+.75(30)
y=4.50+22.50
y=27
y=7.50+.65(30)
y=7.50+19.50
y=27
both equations equal so 30 is the correct distance for when Fast Rental equals Red Rent
Answer:
Part a)
Exact value 24√3 units
Approximate value 41.6 units
Part b) x=52.1 units
Step-by-step explanation:
Part a)
step 1
Find the exact value
Let
h-------> the blue dotted line
we know that
tan(60°)=h/24
h=tan(60°)*24
Remember that
tan(60°)=√3
substitute
h=24√3 units
step 2
Find the approximate value
h=24√3=41.6 units
Part b)
we know that
sin(53°)=41.6/x
x=41.6/sin(53°)=52.1 units
Answer:
A. yes
Step-by-step explanation:
The contestant has a 60% chance of winning because they could either spin 1, 3, or 5.
However, unless there's another player who can only spin evens, it's not fair, because the contestant who spins odds has a 60% chance, while this player will only have a 40% chance.
Answer:
35
Step-by-step explanation:
A=1/2(b_1+b_2)h
A=1/2(4+10)5
A=1/2*70
A=35
