Answer:
p = .7
Step-by-step explanation:
3(p+2.55)=9 3/4
Change the fraction to a decimal
3(p+2.55)=9.75
Divide each side by 3
3/3(p+2.55)=9.75/3
(p+2.55)=3.25
Subtract 2.55 from each side
(p+2.55-2.55)=3.25-2.55
p =.7
252=28 x length x 1/2
252=28 x 1/2 x length
252=14 x length
252/14=length
18 inches= length
From the given data in the problem, the longitude is essentially the same, and using the coordinates, the locations are 8° apart. The 8° is 8/360 of the circumference of the circle. The circumference is 2π • 3960. <span>Substituting, </span><span>(8 • 2π • 3960) / 360 = 4π • 44 = 553 miles. Thus, option B is the answer. </span>
