The amount of seed a landscaper uses and the area

zepelin [54]

Answer/Step-by-step explanation:

Since there is a proportional relationship between amount of seed a landscaper uses and the area of lawn covered, therefore: constant of proportionality = area covered / seed.

The constant of proportionality would be same for all pairs of values given in the table.

Thus:

$\frac{75}{3} = \frac{25}{1} = 25$

$\frac{100}{4} = \frac{25}{1} = 25$

8.4.49 A cow is tethered to one corner of a square barn, 19 feet by 19 feet, with a rope 160 feet long. (See the illustration

SashulF [63]

Answer:

$20096 ft^2$

Step-by-step explanation:

We are given that

Length of rope=l=160 feet

Radius of quadrant of circle=r=160 feet

We have to find the maximum grazing area of the cow.

We know that

Area of quadrant of circle= $\frac{1}{4}\pi r^2$

Where $\pi=3.14$

Using the formula

Area grazed by cow= $\frac{1}{4}\times 3.14(160)^2$

Area grazed by cow= $20096 ft^2$

Suppose M varies directly with S. If M is 900 when S is 500, which equation relates M to S

julsineya [31]

Answer: M = ⁹/₅S

Step-by-step explanation:

M ∞ S -------------------------------- 1

M = KS ------------------------------ 2

K is a constant and need to be calculated

substitute for M and S in 2 to find K

900 = K500

K = ⁹⁰⁰/₅₀₀

= ⁹/₅

Therefore , the equation that connect / relates M to S will be

M = KS

M = ⁹/₅S
