<span>Harold worked 27 hours at a rate of $13.25 per hour.
27 * $13.25 = $357.75 so line 2 is the answer.

Sped 2.4 mile sin 10 minutes. THat means in 1 hour 2.4 x6=14.4 miles per hour. 1 hour=60 minutes. Explanation: So in 1.5 hours it will be 14.4 x1.5= 21.6 miles. Was this helpful? Let the contributor ...
Step-by-step explanation:
All of these terms have a common factor of 2, and when we take that out we get 2(x² + x - 6). To factor the polynomial in the parentheses, we have to find 2 numbers with a product of -6 and a sum of 1, and these are 3 and -2. Therefore, the final answer is 2(x + 3)(x - 2).
Hope this helps!
R=12cm
circumference=2×pi×r
=2×3.14×12
=75.36cm
area = pi×r^2
=3.14×12×12
=3.14×144
=452.16cm^2
<span>Exponent
is a number used to express shorter equation; it is a number that says how many
times you are going to multiply the base number.

Exponents have several laws, here are
some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n
And since we were asked to write an
expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½
