Answer: 27x^5/250

Step-by-step explanation:

I assume that's a fraction on a fraction.

12x^3/25×40/9x^2 = (12x^3 × 9x^2)/1000

= 108x^5/100

= 27x^5/250

The ribbon was 3 1/4 inches wide and had an area of 19 1/2 square inches. What is the length of the ribbon? Please Help Will Giv
miv72 [106K]
Hello!

The formula for finding area is l × w

If the area is 19 ½ inches and it was 3 ¼ inches wide, then the length will be 19 ½ ÷ 3 ¼ (Area ÷ Width)

19  \frac{1}{2} \div 3  \frac{1}{4}

Change both to improper fraction

19  \frac{1}{2} =   \frac{39}{2}

3  \frac{1}{4} =  \frac{13}{4}

\frac{39}{2} \div  \frac{13}{4}

Keep 39/2
Change ÷ to ×
Flip 13/4 = 4/13

\frac{39}{2} \times  \frac{4}{13} =  \frac{156}{26} = 6

The lakeside marina charges a $35 rental fee for a boat in addition to charging $15 per hour. Part D:what information does the i
STALIN [3.7K]

Answer: B.The cost of rental fee only

Step-by-step explanation:

The $35 is the cost of the rental fee only. The person would then have to pay a further $15 for every hour they use the boat.

Essentially, the $35 is the fixed cost associated with the rental and the $15 is the variable cost to do so. If this were in a linear equation format it would take the form: y = 15x + 35.
