Answer:
Builder is right.
Step-by-step explanation:
circumference, C = 10 feet
Let the radius of circular window is r.
Use the formula for circumference.
C = 2 x π x r = 10 .... (1)
10 = 2 x π x r
r = 1.59 ft
The formula for the area of circular window
A = π r²
Differentiate with respect to r.
dA/dr = 2 x π x r
Differentiate again with respect to r.
d²A/dr² = 2 π
It is positive for any value of r so the area of minimum.
So, minimum area is
A = 3.14 x 1.59 x 1.59 = 8 ft
So, the minimum area id 8 ft². The builder is right.
A straight line is 180°, so you add these two angles together because they make a straight line:
3x° + 75° = 180°
To find "x", isolate/get the variable "x" by itself in the equation. Subtract 75° on both sides
3x° + 75° - 75° = 180° - 75°
3x° = 105° Divide 3 on both sides to get "x" by itself
x = 35°
PROOF
3x° + 75° = 180° Substitute/plug in 35 into "x" since x = 35°
3(35)° + 75° = 180°
105° + 75° = 180°
180° = 180°
it should be 1.6 hope that helps you
Answer:
x= 27
Step-by-step explanation:
a triangle always has 180 degrees, therefore:
(3x-17)+(x+40)+(2x-5)= 180
6x+18=180
6x=162
x=162/6
x=27
The equation with (x) in dogs and (y) in dollars is 
First, you must set up your equation.
Then, you must add like terms to simplify the equation
