Answer:
y=6/5x+13
Step-by-step explanation:
6y=-5x+16
Divide by 6
y=-5/6x + 8/3
Slope: 6/5 (opposite reciprocal)
7=-5(6/5)+b
7=-6+b
b=13
Answer:
see below
Step-by-step explanation:
4 quarts for 12 square yards means the constant of proportionality is 3 square yards per quart.
y = 3x
Fill in x=5 to find the square yards for 5 quarts:
y = 3·5 = 15
Mona can clean 15 square yards with 5 quarts.
Each day, 30 cents are added onto the fee.
-3 days would mean -3 * 30 cents on the fee, which is -90 cents, or -0.90.
and -2.5 charges of 30 cents would be -75 cents!
...but you can't have negative days or fees, so A and B are out of the question.
4.5 charges of 30 cents IS $1.35...
...but the library charges by day, of course.
8 charges of 30 cents would be $2.40, and both of these are realistic possible numbers.
Height = 9 ft
Radius = Diameter/2 = 12/2 = 6 ft
Volume of a cone = 1/3πr²h
= 2/3 × 3.14 × 6 × 6 × 9
= 339.12 ≈ 339.1 cubic foot.
