Tell me, what are you doing?
Área, perimeter? Basically what kind of operation is it asking for?!
Answer: m<1 is 60, m<2 is 60, and m<3 is 120
Step-by-step explanation:
M<1 is 60 and m<2 is also 60 because the interior triangle angles have to equal 180 so M<1 + m<2 + 60 = 180 so m<1 and m<2 are both sixty.
m<3 is 120 because m<2 and m<3 are supplementary so if a supplementary angle is equal to 180 then m<2 + m<3 = 180 and m<2 is 60 so m<3 is 120.
Answer:
x^2 +y^2 -40x -24y -81 =0
Step-by-step explanation:
We can write the equation of a circle in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
Assuming that Pamela's cabin is the center
( x-20)^2 + (y- 12)^2 = 25^2
We want to get to general form
x^2 + y^2 + Dx + Ey + F = 0,
Distributing
x^2 -40x +400 + y^2 -24y +144 = 625
x^2 +y^2 -40x -24y +544 -625 =0
x^2 +y^2 -40x -24y -81 =0
Answer:
Upstream = 0.5 hour.
Downstream = 0.366 hour.
Step-by-step explanation:
Speed of fram in still water (u) = 2.6 mph.
Speed of water (v) = 0.4 mph .
<h3>Time taken by fran to swim 1.1 mi upstream.</h3>
Speed upstream = u - v = (2.6 - 0.4) mph = 2.2 mph
So the time taken = 
= 0.5 hour.
<h3>Time taken by fran to swim 1.1 mi downstream.</h3>
Speed downstream = u + v = (2.6 + 0.4) mph = 3 mph .
So the time taken = 
= 0.366 hour .
