Hi there there's several ways this could be proven one way us to consider the allied angle theory where two angles formed between parallel lines are supplementary which in this case can be proven by

2(45)+90=180⁰ ✔

or 3(45)+45=180⁰✔

this would not be the case if it wasn't parallel

Consequently, you can also use the alternate angle theory where you essentially extend one of the lines and you'll see two equal alternate angles

Big Bob’s Pizza is having a special on pizza and is offering two different choices:
Anna71 [15]

Answer:

The Choice N#1 will give more pizza for your money

Step-by-step explanation:

step 1

Find the area of one slice Choice #1

The area of the circle is equal to

A=\pi r^{2}

we have

r=22/2=11\ in ----> the radius is half the diameter

assume

\pi =3.14

The area of one slice is equal to

A=(1/8)\pi r^{2}

substitute

A=(1/8)(3.14)(11)^{2}

A=47.4925\ in^{2}

Divide the cost by the area

4.95/47.4925=0.10\frac{\$}{in^{2}}

step 2

Find the area of the entire personal pizza Choice # 2

The area of the circle is equal to

A=\pi r^{2}

we have

r=6/2=3\ in ----> the radius is half the diameter

assume

\pi =3.14

substitute

A=(3.14)(3)^{2}

A=28.26\ in^{2}

Divide the cost by the area

3.75/28.26=0.13\frac{\$}{in^{2}}

therefore

The Choice N#1 will give more pizza for your money

An electrician charges $40 to come to your house she also charges $55 for each hour that she works the electrician charges you a
s2008m [1.1K]
First lets remove the initial fee
190 - 40 = 150
150 is how much she is charging you per hour.
If each hour is 55, lets divide 150 by 55.
150 \div 55 = 2.7
She charged you for 2.7 hours (almost 3) of service
