Answer:
64:1
It doubles every 10 minutes, so it multiplies by two 6 times in an hour. 1x2x2x2x2x2x2 = 64
we know that
2pi radians (full circle) has an area of-----------------> 100pi
then
(2pi/5) radians----------------------------> X
X=(2pi/5)*100pi/2pi---------> 20pi units²
the answer is
20pi units²
Answer:
4v^2-25
Step-by-step explanation:
(2v+5)(2v-5)
Using (a-b)(a+b)=a^2-b^2, simplify the product
(2v)^2-5^2
To raise a <u>product to a power</u>, raise each factor to that power.
4v^2-5^2
Evaluate the <u>power.</u>
4v^2-25
5t=v-u (Subtract u on both sides)
t=(v-u)/5 (Divide by 5 in both sides)
75 is 125% of 60. Hope this helps! :)
