ale4655 [162]

Answer:

B. 3.19b + 4.59m = 137.24

3.49b + 4.39m = $140.04

Step-by-step explanation:

A B

Bread $3.19 $3.49

Milk $4.59 $4.39

Sue paid $137.24 in supermarket A

Sue paid $140.04 in supermarket B

Let

Price of bread A=$3.19

Price of bread B=$3.49

Price of milk A=$4.59

Price of milk B=$4.39

Quantity of Bread=b

Quantity of Milk=m

Pb=price of bread

Pm=price of milk

Qb=Quantity of bread

Qm=Quantity of milk

For each supermarket

Supermarket A Equation

PbQb + PmQm =$137.24

3.19b+ 4.59m = 137.24

Supermarket B Equation

PbQb + PmQm=$140.04

3.49b + 4.39m = $140.04

Combining both equations

3.19b + 4.59m = 137.24

3.49b + 4.39m = $140.04

Answer:

B. Doubled

Step-by-step explanation:

The formula to find the circumference of the circle is

$C=2\pi r$

Now our problem says that the radius is doubled. Hence the new radius is 2r

Hence the new circumference will be

$C'=2 \pi 2r$

$= 2 \times 2\pi r$

$=2C$

Hence our circumference gets doubled.

levacccp [35]

Answer: <em>Tax rate per dollar = .06536</em>

Given:

Amount needed from property tax = $915000

Value of assessed property = $14000000

Therefore, we'll compute tax rate per dollar as:

Tax rate per dollar = $\frac{Property\ tax\ amount}{Value\ of assessed\ property}$

= $\frac{915000}{14000000}$

= .06536
