The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8

Step-by-step explanation:
i took the test
f(x) = 57 (19)^(x-4)
The domain is the input or x values
what are the allowed x values
we can put in any values of x we want and the function still works
Domain: all real values
The range is the output or the y values
It will always be greater than 0
Range: y> 0 or all positive real numbers
Answer: $0.95
Step-by-step explanation:
Hi, to answer this question we simply have to add all amounts raised by the government, the manufacturer, and the retailer.
Mathematically speaking:
$0.20+$0.60+$0.15 = $0.95
So, a consumer pays $0.95 more per bottle of soda.
Feel free to ask for more if needed or if you did not understand something.
Answer:
36
Step-by-step explanation:
171/(4+0.75) =36
you want it to be in minutes, so calculate the 45 seconds over 60 seconds, which is 0.75. Add that to the 4 minutes, and divide the total number of copies over the time used, and you have speed/minute.
