Answer:
$74.67
Step-by-step explanation:
Let p represent the original price. Then the relation is ...
$56 = p - 0.25×p
$56 = 0.75p
$56/0.75 = p ≈ $74.67
The original price was $74.67.
Answer:
P = 61.70 feets
Step-by-step explanation:
Based on the information given :
For fencing , We need to calculate the perimeter of the semicircle ;
Perimeter of a semicircle is given as :
P = πr + 2r
P = perimeter ; r = Radius = 12 feets
P = 12π + 2*12
P = 12π + 24
P = 61.699111 feets
P = 61.70 feets
To. Obtain how much.
We multiply the perimeter by the cost per feet.
6x = 4y - 8
4y = 6x + 8
y = (3/2) x + 2
Answer: Slope 3/2, y intercept 2
There are 8 black chips and 6 white chips, 14 chips in total. In this situation the probability to pick a black chip is 8/14=4/7.
When one white chip was removed, then only 5 white chips left and the total number of chips became 13. In this situation the probability to pick a black chip is 8/14=4/7.
When second white chip was removed, then ther left 4 white chips and the total number of chips became 12. Now the probability to pick a black chip is 8/12=2/3 as needed.
Answer: Must be removed 2 white chips. Correct choice is B.
