Hey there! I'm happy to help!
Since this mural is a square, all the sides are the same. This means that you square on of the sides to get the area (multiply it by itself). If we have the area and want to find a side, we just go backwards and use something called the square root!
If we plug this into our calculators...
√138≈11.74734
We see that is closest to B. 12 ft.
You could also figure this out without a calculator. 138 is very close to 144, which is 12². All the other answer options are way too big.
Have a wonderful day! :D
Answer:
- $5.60 sales tax
- $75.60 total cost
Step-by-step explanation:
You have correctly found the sales tax to be ...
$70.00 × 0.08 = $5.60 . . . sales tax
The total cost of the item is the selling price with the tax added:
$70.00 +5.60 = $75.60 . . . total cost

Explanation:
Given that we have the slope and a point on the graph we can use the point slope formula to find the equation of the line.
Point-Slope Formula:
y

y
1
=
m
(
x
−
x
1
)
, where
m
is the slope of the line and
x
1
and
y
1
are x and y coordinates of a given point.
We can summarize the information already given:
m
=

y

Using this information, we can substitute these values onto the point-slope formula:
y

The equation above is the equation of the line in point-slope form. If we wanted to have the equation in
y
