66!

Surprised I got that.
360 - 42 - 42 - 72 - 72 = 132
132 / 2 = 66
If you look opposite from where the angles are given they are the same angles.

\textit{equal slopes}\\
\textit{different y-intercepts}

for example, let's look at the first set

y+3x =5   or  y = -3x+ 5
and               y = -3x + 2
                    y =  m  + b

the slopes are equal, the y-intercepts differ
that means, they're just parallel lines, no solution

finlep [7]

Answer:

C) English

Step-by-step explanation:

I don't really know how to explain it, so I'll show you instead.

For science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

So,

0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.016

For English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

So,

0.25 x 0.25 x 0.25 x 0.25 = 0.004

They will have to study English (0.004) because it is lower than science (0.016).

3. The cost of the city permits needed to build this building is 150,000 no matter how many floors with
natima [27]

Answer:

P(x) = 150000

Slope = 0

Step-by-step explanation:

Given

Cost = 150000

Solving (a): The cost function:

From the given parameter, it shows that the number of floor has no effect on the floors.

So, represent the floors with x.

The cost function is:

P(x) = 150000

Solving (b): The slope and its interpretation

A function is represented as:

f(x) = b + mx

Where:

m=slope

By comparing: f(x) = b + mx to P(x) = 150000

m = 0

So:

Slope = 0

<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
