Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount of money borrowed.
P represents the principal or amount of money borrowed.
R represents interest rate
T represents the duration in years.
From the given information,
P = $450
R = 5%
T = 1 year
I = (450 × 5 × 1)/100
I = $22.5
the total amount that she pays for the Soundsystem is
450 + 22.5 = $472.5

Step-by-step explanation:
Answer:
circumference of the base
Step-by-step explanation:
Given that
The height of the cylinder is 10 inches
And, the 8 inches show the circumference of the base or the circumference of the circle
So,
C = 2r π
or
8 = 2r π
So, the 8 inches represent the same as shown above
Hence, the last option is correct
Note 1: A constant number (A number without an exponent) will have the degree of 0. Always.Note 2: A variable without a visible exponent obtains an exponent of 1. Ex. x = Note 3: The operation sign before a coefficient/constant indicates if it's positive or negative. If no subtraction (or even addition) sign is in front of a value, it's positive. If a subtraction sign stands in front of a value, the value is negative. If an addition sign stands in front of the value, the value is negative.Note 4: When a number is not standing in front of a variable, it translates to 1 times that variable. Ex. x = 1xNote 5: coefficients contain a number and a variable.

Step 1: Remove the parentheses. [we do this by distributing what's in the parentheses by 1. For the first part (-7ab + 7a-1), you can simply just remove the parentheses because it doesn't affect what's in the parentheses whatsoever. For the second one, (ab +8) however, you distribute -1 which gets us, essentially, different number signs.
