Answer:
C. 25/6 ft²
Step-by-step explanation:
Let's call the dimensions of Rectangle B x and y. Then ...
xy = 5 ft²
and
x² = 6 ft²
We want to find the value of y². Solving the first equation for y, then substituting for x², we have ...
y = (5 ft²)/x
y² = ((5 ft²)/x) = 25 ft⁴/x² = 25 ft⁴/(6 ft²)
y² = (25/6) ft² . . . . . . . matches choice C
Answer:
Very simply divide the 3 months cost, $180, by 3.
180/3 = 60
y = 60x
Answer:
Step-by-step explanation:
Cost price = $n
Mark up price = selling price- cost price
= (20% × $n)
Selling price = $n + (20% × $n)
Sales tax = 5% × ($n + (20% × $n))
Total cost = selling price + sales tax
Total cost = $n + (20% × $n) + 5% × $n + (20% × $n)
= 1.2 × $n + 0.06 × $n
= 1.26 × $n.
Answer: 50 cents
Step-by-step explanation:
Company charges 8 cents per call and the call in question is 3 minutes. Cost is;
= 3 * 8
= 24 cents
Company however stipulates that a call is 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater.
<em>50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.</em>
