Jessica has a circular birdbath in her backyard with a radius of 1.25 feet. She wants to place a decorated border around the cir
Alexxandr [17]

Answer:

The total cost is <em>28.26.</em>

Step-by-step explanation:

The radius of the birdbath is <em>1.25 feet.</em>

The cost per foot is <em>3.6</em> .

<em>The formula for perimeter of circle is given by,</em>

<em>= 2πR , where R is the radius of circle.</em>

Inserting the above value of radius in the equation above,

circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85 ft^{2}

Thus the total cost is,

= (7.85)(3.6) = 28.26

Kaya's family spends $105 to rent a boat for 7 days. The total cost, c, of the boat rental is proportional to the number of days
Elza [17]

Answer:

c=15d

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

Let

c ----> the total cost of the boat rental

d ---> is the number of days, the family rents the boat

we know that

Kaya's family spends $105 to rent a boat for 7 days

so

For d=7 days, c=$105

Find the value of the constant of proportionality k

k=\frac{c}{d}

substitute the given values

k=\frac{105}{7}=\$15\ per\ day

therefore

The linear direct equation is equal to

c=15d
