Answer: 648</h3>
Explanation:
For the first slot, we have 9 digits to choose from (1 through 9).
Whatever we pick for the first choice, we have 9 choices left for the second slot. Say we picked 2 for the first slot. That means we have {0,1,X,3,4,5,6,7,8,9} to choose from. I used X to indicate we can't pick that digit any more. You'll see there are 9 items in that list.
Then for the third slot, we had 8 choices to pick from
Overall we have 9*9*8 = 81*8 = 648 different area codes possible where the first digit cannot be zero.
Answer:
82.49 percent were at least high school graduates.
Step-by-step explanation:
We have been given that at 1950 x=0
and at 1960 x=10
And following this pattern at 2000 x=50
So, we have coordinates:
(0,34.7) and (50,87.8) for two point form we will find a function:
Using:
Substituting the values in the formula we get:
y=1.062 x+34.7 is the linear function
(b) Now, we need to find the value at x= 1995 which will be equal to 45 according to the pattern followed
Put x=1995 in the function above we get:
y =1.062(45)+34.7
y=82.49 percent were at least high school graduates.

Answer:
Step-by-step explanation:
This means that we just subtract the exponents with identical bases so
2⁷/2³=2⁴ (7-3)
3⁶/3³=3³ (6-3)
5⁸/5⁷=5 (8-7) put them together and you get the answer
Answer:
Expenses for purchasing is $245 ,Revenue $479 and Total profit $ 234
Step-by-step explanation:
Cost of two blouses = 2× 25 = $50
Revenue from blouses = 2× 38 = $76
Profit of blouses = 76- 50 = $26
Similarly cost of 3 skirts = 3×15 = $45
Revenue from Skirts = 3×26 =$78
Profit from skirts = 78-45 =$33
Now cost price of pants = 5×30 =$150
Revenue from Pants = 5×65 =$325
Profit from pants = 325-150 = $175
So Jayla's expenses for purchasing = 50+45+150
= $245
Revenue = 76+78+325
= $479
Total Profit = 479 -245
= $234
