Answer:
a
Step-by-step explanation:
sec (thita) = squrt (5)
squaring on both sides:
sec^2 (thita) = 5 - equation 1
1 + tan^2 (thita) = 5
tan^2 (thita) = 4
tan (thita) = 2.
= tan (thita) - squrt(5)sin(thita)
= 2 - squrt(5) x 2/ squrt(5)
= 0
from eqn - 1
sec(thita) = squrt(5)
cos(thita) = 1/ squrt(5)
sin(thita) = squrt ( 1- 1/(squrt (5))^2)
sin(thita) = 2/ squrt(5) .
So acting, eh?
you can walk 10 steps in 5 seconds
how many steps can you walk in 25 seconds?
(walk to test this thingie)
reasoning is 25 is 5 times 5 so 10 times 5=50 so 50 steps
Make the denominators the same number. Then do the problem as you would regularly without fractions
Answer:
0.8
Step-by-step explanation:
Given,
Price of an item = X dollars
Discount = 20%
Amount of discount = 20% of Price of item
Amount of discount = \frac{20}{100}*X=0.2X10020∗X=0.2X
Price of item after discount = Price of item - Amount of discount
Price of item after discount = X-0.2X = 0.8X dollars
The discount price will be 0.8x dollars
