The answer is the third choice: -1
So for a straight line the total is 180 degrees, so angle rpq is 180 - 123 which. makes 57 °. and arc length is just circumference of circle x 57/360. so here, it would be 20πx57/360 so the answer is 9.948..... and round it up 9.9 cm
Answer: Equilibrium price would be $13.33 and equilibrium quantity would be 133.3 units.
Step-by-step explanation:
Since we have given that
Demand function is stated as
Supply function is stated as
We need to find the equilibrium price and quantity for this device.
For equilibrium, D(p) = S(p).
so, it becomes,
and when we put the value of p in any function:
Hence, Equilibrium price would be $13.33 and equilibrium quantity would be 133.3 units.
Answer:
Joe's age is 93 years
Aaron's age is 31 years
Christina's age is 25 years
Step-by-step explanation:
Let
x ---->Joe's age
y ----> Aaron's age
z----> Christina's age
we know that
Joe"s Age Is three times Aaron's age
----> equation A
Aaron is six years older than Christina
isolate the variable z
----> equation B
The sum of their ages is 149
----> equation C
solve the system by substitution
substitute equation A and equation B in equation C
solve for y
Combine like terms left side
Adds 6 both sides
Divide by 5 both sides
<em>Find the value of x</em>
---->
<em>Find the value of z</em>
----
therefore
Joe's age is 93 years
Aaron's age is 31 years
Christina's age is 25 years
