I need help. Someone please give me a explanation of how to do this.
Answer:
You take 6% of a number and the resulting number is 27.
To do this you need to change the percent into a fraction.
6% = 6/100
This is the number you need to multiply to the number you need to find, A.
6/100 A = 27
Solve for x
6 A = 27x100
A= 2700/6
A = 450
Check your answer:
6/100 (A) = 27
6/100 (450) = 27
(6x450) /100 = 27
2700 / 100 = 27
27 = 27

D. 5040
The value of ₇P₇ or P(7, 7) is 5040 after using the permutation formula option (D) 5040 is correct.
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
= ₇P₇
Here P represents the permutation:
We can calculate the value of ₇P₇ using the formula:
P(n, r) = n!/(n - r)!
n = 7
r = 7
Plug the above values in the formula:
₇P₇= P(7, 7) = 7!/(7 - 7)!
₇P₇ = 7!/(0)!
₇P₇ = 7!
₇P₇ = 7×6×5×4×3×2×1
The above represents a mathematical operation, Now multiply all the numbers.
₇P₇ = 5040
Thus, the value of ₇P₇ or P(7, 7) is 5040 after using the permutation formula option (D) 5040 is correct.

each. What is the maximum number of donuts
Amber can buy with $37? Write an inequality to
represent this situation who's the
Inequality
A: 1.75c + 1.50d 5 37t Go to #9
B: (1.75 +1.50) 3 < 37 Go to 10
C: 1.75 +1.500 > 37 Go to #1
D: 1.75 + 1.50d < 37 Go to #12
pls give me the answer
Answer:
d
Step-by-step explanation:
1.75 ( would be the coffee) + 1.50d (donuts each but an unknown quantity)
total amount must be less than $37 dollars
Your answer would be 37.00 - 1.75 = 35.25 cents
35.25 / 1.50 = 23.5 donuts - you can not purchase a half of a donut so you can buy 1 coffee and 23 donuts for $36.25
