Answer:
48.75$
Step-by-step explanation:
Since the original price is 65$ and you are getting 25% off, you would now be paying 75% of the original price.
65*75%=48.75
_______________________________________________________
You could also take the amount of discount you're getting...
65*25%
and then subtract the amount of discount your getting from the original price
65-(65*25%) = 48.75

Answer:
1/6 of the third workers time
Step-by-step explanation:
one of the people is budgeted for 1 /2 of his time to the project and a second person for 1/3 of her time
Let x be the third workers time
Let the completed job time = 1
Time taken for 3 workers to complete the job = 1
now we solve for x
LCD = 2*3 = 6
We multiply the whole equation by 6
3 + 2 +6x = 6
5 + 6x = 6
subtract 5 on both sides
6x = 1
divide both sides by 6
Answer:
theta = 60
Step-by-step explanation:
let the radius BE R
and angle be theta
formula
theta/360 x pi r2= 1/6 x pi r2
pi r2 gets canceled on both sides
theta/360 = 1/6
theta = 360/6
= 60
