A spherical water tank holds 7500 feet^3 of water. what is the diameter?

Mathematics

Rzqust [24]3 years ago
6 0
Vsphere=4/3pir^3
7500=4/3pir^3
times both sides by 3
22500=4pir^3
divide both sides by 4
5625=pir^3
divide bot sides by pi
1790.4931=r^3
cube root both sides
12.142950=r

2r=d
d=24.28590063 ft

Chang will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an add
oksano4ka [1.4K]

Answer:

  • 450 miles
  • $117.50

Step-by-step explanation:

The difference in fixed cost is $9; the difference in per-mile cost is $0.02. The difference in per-mile cost will equal the difference in fixed cost for a distance of ...

   $9.00/($0.02/mi) = 450 mi

At that distance, the rental cost is ...

  $50 +450×$0.15 = $50 +67.50 = $117.50

Both plans will cost $117.50 for 450 miles of driving.

Need help fastppz help me.
Papessa [141]

a)

Using 2 points (6,9) and (10, 13)


b)

Slope = (13 - 9) / (10 - 6) = 4/4 = 1

Slope = 1


c)

Point slope form

y - 9 = 1(x - 6)

or

y - 13 = 1(x - 10)

Hope it helps

First, let's see if the measuring tools work for you. what is the angle of refraction corresponding to the angle of incidence eq
Dafna1 [17]
The concept to answer this question can be bought from physics. 
The Snell's law of refraction says that, the ration of sine of angle of incidence to the the sine of angle of refraction is constant for a given media.

This means; 
(sinθ1)/(sinθ2) = k
Where θ1 = angle of incidence and
            θ2 = angle of refraction 
            k = constant

(sinθ1)/(sinθ2) = k
sinθ2 = k/sinθ1
         = k/sin25
         = k/0.422618261
         = 2.366k

The angle of refraction, θ2 = anti-sin(2.366k)
