Answer:

81 cars

756 trucks

63 wheelers

Step-by-step explanation:

1 mile = 5280 feet

So the jam is 10 miles = 52800 feet

Cars' length = 2 % of the 52800 = 1056 feet

Trucks' length = 29% of the 52800= 15312 feet

Wheelers' length = 9%of the 52800= 4752 feet

Average car is 13 feet in length

The number of cars = 1056 feet/13= 81.23 almost 81 cars

The average truck is 20 feet in length

Number of trucks in 15312 feet=15312 feet/20= 765.6= 756 trucks

The average 18 wheeler is 75 feet in length.

Number of wheelers in 4752 feet= 4752 feet/75= 63.36= 63 wheelers

A zookeeper weighed an African elephant to be 9x10^3 pounds and an African lion to be 4x10^2 pounds. How many times greater is t

maria [59]

Answer: 22.5 . The weight of the elephant is "22.5 times greater" than the weight of the lion.
_________________________________________________________
Explanation:
_________________________________________________________

(weight of lion) * (x) = (eight of the elephant) ; Solve for "x" .
_____________________________________________________
→ Divide each side of the equation by "(weight of lion)" ;
to isolate "x" on one side of the equation ; and to solve for "x" ;
_________________________________________________________

→ (weight of lion)*(x) / (weight of lion) = (weight of the elephant) /
(weight of lion) ;
________________________________________________________
→ x = (weight of the elephant) / (weight of lion) ;
__________________________________________________________
→ Plug in our "given values" ; and solve for "x" ;
__________________________________________________________
→ x = (<span>9*10</span>³) / (4*10²) = (9*10⁽³⁻²⁾) / 4 = (9*10¹) / 4 ;
__________________________________________________________
→ x = 90 /4 = 25/2 = 22.5 ; which is our answer.

Find the surface area of a smooth golf ball with the minimum diameter allowed by the United States golf association

meriva

Surface area o fthe ball = 4 * 3.14 * radius^2

if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84

so surface area = 4 * 3.14 * 0.84^2 = 8.862
