Aloiza [94]

Answer:

62 pages

Step-by-step explanation:

The total cost function is given as below:

C= 0.06p + 12.75

C=total cost for printing= $16.47

0.06= variable printing cost per page

p=number of pages prinited=the unknown

12.75=monthly fixed printing cost

16.47=0.06p+12.75

16.47-12.75=0.06p

3.72=0.06p

0.06p=3.72

p=3.72/0.06

p=62 pages

0: Jimmy is installing a gravel path along the diagonal of a rectangular garden. The garden measures 24 feet wide by 32 feet lon
murzikaleks [220]

Answer: it will cost $280

Step-by-step explanation:

The diagonal of the rectangular garden divides it into two equal right angle triangles. The diagonal represents the hypotenuse of each right angle triangle. The length and width of the rectangle represents the adjacent and opposite sides of the right angle triangle. To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore

d² = 24² + 32²

d² = 576 + 1024 = 1600

d = √1600

d = 40 feet

If the path is 2 feet wide, then the area of the path is

Area = 40 × 2 = 80 ft²

If gravel costs $3.50 a square foot, then the cost to install the gravel path is

3.5 × 80 = $280
