Answer:
0.104 is 10.4%
Step-by-step explanation:
Answer:
$140.48
Step-by-step explanation:
Let x represent dialed units.
We have been given that a quarterly telephone bill consist of $79.15 rental plus 4.7 cents for each dialed unit.
4.7 cents = $0.047
Cost of dialing x units would be .
Total cost of dialing x units would be .
Let us find cost of dialing 915 units by substituting in above expression.
Now, we will find 15% of sales tax as:
Total bill:
Therefore, Mrs. Jonas's bill would be $140.48.
Answer:
length is 39ft
width is 9ft
Step-by-step explanation:
let 6x - 15 be the length and x be the width
the perimeter of a rectangle is 2(L+W)
96 = 2(6x - 15 + x)
96 = 2(7x - 15)
96 = 14x - 30
126 = 14x
x = 9
Length is 6x - 15
6(9) - 15
54 - 15 = 39
x2 + 3x + 9
3x - 11
x2 + 3x - 4
Answer:
x^2+3x-4
Step-by-step explanation:
Answer:
Step-by-step explanation:
s = n(a + 1)
n(a + 1) = s
a + 1 = s/n
a = s/n - 1
5 to the power of 1 over 6
5 to the power of 2 over 3
5 to the power of 7 over 6
Answer:
5 to the power of 5 over 6 =
Step-by-step explanation:
1)Let's define some properties about exponent:
For example :
2)Another property of exponent is :
For example :
This means that when we have two exponential functions with the same base that are multiplying between them, we can sum the exponents in order to make a new exponential function with the same base.
Using this two properties we can solve the problem.
Now,
Therefore, the final expression is
⇒
The correct answer is :
5 to the power of 5 over 6.
