I need help on this one.
Flura [38]

Answer:

1) 180 is a straight line, so 180 - 118 = <em>62</em>

2) 180 degrees are in a triangle, so 180 - (62) - 73 = <em>45</em>

3) 180 is a straight line, so 180 - 73 = 107. There are 180 degrees in a triangle, so 180 - 49 - 45 = <em>86</em>

A rectangular parking lot is 120 feet long and 75 feet wide. Diego made another scale drawing of the parking lot at a scale of 1
andrew11 [14]

Answer:

We kindly invite you to read carefully the explanation detailed below for further details.

Step-by-step explanation:

At first we understand that Diego converted length and wide units from feet to inches (1\,ft = 12\,in) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:

Step 1 - Unit conversion:

l = 120\,ft (l - Length)

l = 120\,ft\times \frac{12\,in}{1\,ft}

l = 1440\,in

w = 75\,ft (w - Width)

w = 75\,ft\times \frac{12\,in}{1\,ft}

w = 900\,in

Step 2 - Applying scaling:

l' = \frac{l}{180} (l' - Scaled length)

l' = \frac{1440\,in}{180}

l' = 8\,in

w' = \frac{w}{180} (w' - Scaled width)

w' = \frac{900\,in}{180}

w' = 5\,in

Simplify each expression.
Elina [12.6K]

Step-by-step explanation:

remember that x^-n means 1/(x^n).

x^a × x^b = x^(a+b)

x^a / x^b = x^(a-b)

(x^a)^b = x^(a×b)

(x×y)^n = x^n × y^n

so,

a^2 / a^-2 = a^(2 - -2) = a^4

and

b^-3 / b^2 = b^(-3 - 2) = b^-5 = 1/(b^5)

that means we have then :

(a^4 × b^-5)^2 = (a^4)^2 × (b^-5)^2 = a^8 × b^-10 =

= a^8 / b^10 = a⁸/b¹⁰
