ANSWER

EXPLANATION
The given line passes through the origin, hence it has equation of the form,

Therefore y varies directly as x.
The line passes through the point (3,1)
This implies that,


Hence the constant of variation is

The equation is

Answer:
706.5 ft²
Step-by-step explanation:
A. Width of the rectangle
The formula for the area of a rectangle is
A = lw
But, l = 3w, so,
A = (3w)w
= 3w² = 12
w² = 4 Divided each side by 3
w = 2 ft Took the square root of each side
B. Length of rectangle
l = 3w = 6 ft
C. Diameter of circle
d = 5l = 5 × 6 = 30 ft
D. Radius of circle
d = 2r
r = d/2 Divided each side by 2
r = 30/2 = 15 ft
E. Area of circle
A = πr² = 3.14 × 15² = 3.14 × 225 = 706.5 ft²
The area of the circle is 706.5 ft².
Answer:
The answer is "sugar= 200g, flour=600g, and butter=400g".
Step-by-step explanation:

Answer choice d (7) would be monomial because it's just one number by itself not attached to anything :)
Answer:
step 1. <2 + 40° = <1
step 2. <1 + 72° = 180°
step 3. <1 = 108°
step 4. <2 = 108° - 40° = 68°.
