Answer:
$ 117.36
Step-by-step explanation:
On the drawing, the rectangular room measures 3 inches by 2 inches, we can convert to feet (using a scale of Inch - 2 feet )
(3 inches ×2) by (2 inches ×2)
= 6 feet by 4 feet
The Area of the room can now be calculated as
Area=( 6 feet × 4 feet)
= 24 ft^2
how much will the new carpet cost?
we know that the carpet costs $4.89 per square foot, then the cost by the area of the room= (Area× $4.89 per square foot)
=24 ft^2 x $4.89
=$ 117.36
Hence, the new carpet cost is $ 117.36
Straight line equation has a general form of
Where m is the slope
and c is the y intercepted part.
So now, you need to find the value of the slope (m) and the y intercept (c).
As you can notice the line intercepts with y axis in (0,1) So c=1.
And then you want to find 2 points along that line to found the slope from, we found on already (0,1) and the other one can be any point along the line, let's take (2,3).
Then use them to find the slope.
So now
m=1 and c=1.
The equation of this line is y=x+1
Hope this helps!

Answer:
Step-by-step explanation:
Answer:
Diameter = 19.33
Step-by-step explanation:
Imaging a radius line from O to the endpoints of the 7. call this line R.
Label the part of the vertical line from O to the 90 degree intersection y.
Now you have a right triangle.
Using the Pythagorean theorem:
R² = 7² + y²
also
y = R - 3
substitute for y:
R² = 49 + (R-3)²
R² = 49 + R² - 6R + 9
simplify:
0 = 58 - 6R
6R = 58
R = 9.6667
Diameter = 2(9.6667) = 19.33
