natulia [17]

Answer: 2.5%

Step-by-step explanation:

Let's use the rule of 3 here.

If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.

Let's put money on one side and percentages on the other.

$\frac{275000}{6875}=\frac{100}{x}$

Solve for x;

$x=\frac{6875*100}{275000}$

$x=2.5$

vitfil [10]

Answer:

$c = 16.392\,\frac{USD}{ft^{2}}$

Step-by-step explanation:

The surface area of the cone shaped roof is:

$A_{s} = \pi\cdot (10\,ft)\cdot (6\,ft)$

$A_{s} \approx 188.496\,ft^{2}$

The cost of roofing per square feet is: (USD stands for US dollar)

$c = \frac{3089.76\,USD}{188.496\,ft^{2}}$

$c = 16.392\,\frac{USD}{ft^{2}}$

Maggie's brother is 6 years younger than four times her age. The sum of their ages is 39. How old is Maggie?

poizon [28]

We can set Maggie's age to x

If her brother is six years younger than four times her age, than her brother must be equal to: 4x-6

Since the sum of their ages is 39, we can set up an equation.

(Sum of Maggie's age) + (sum of Maggie's brother's age) = 39

x + (4x -6) = 39

5x -6 = 39

5x = 45

x = 9 , Maggie's age is 9
