Answer:

Probability chosen student received A in one or both = 0.191 (Approx.)

Step-by-step explanation:

Given:

Total number of student = 490

66 = received A in general chemistry

58 = received A in calculus

30 = received A in both general chemistry and calculus

Find:

Probability chosen student received A in one or both.

Computation:

Probability chosen student received A in one or both = 66/490 + 58/490 - 30/490

Probability chosen student received A in one or both = 94/490

Probability chosen student received A in one or both = 0.191 (Approx.)

Answer:

V=97.6\ in^3

Step-by-step explanation:

step 1

Find the volume of the cylinder

The volume of the cylinder is equal to

V=\pi r^{2}h

we have

r=4/2=2\ in ---> the radius is half the diameter

h=8\ in

substitute

V=\pi (2)^{2}(8)\\\\V=32\pi\ in^3

step 2

Find the volume of the cone

The volume of the cone is equal to

V=\frac{1}{3}\pi r^{2} h

we have

we have

r=2\ in ---> the radius is the same that the radius of the cylinder

h=0.70\ in

substitute

V=\frac{1}{3}\pi (2)^{2} (0.70)\\\\V=0.93\pi\ in^3

step 3

Find the volume of the plastic object

we know that

The volume of the plastic object is equal to the volume of the cylinder minus the volume of the cone

so

V=32\pi-0.93\pi=31.07\pi\ in^3

assume

\pi=3.1416

V=31.07(3.1416)=97.6\ in^3

A water tank is 1/8 full the tank is 3/4 full when 42 gallons are added to the tank how much water was originally in the tank
masha68 [24]
<span>A water tank is 1/8 full. The tank is 3/4 full when 42 gallons are added to the tank. How much water was originally in the tank? (I rewrote it, your wording was messed up)

3/4 = 6/8 
1/8 + 6/8 = 7/8 = 42 gallons
42 divided by 8 = 5 1/4

So, the answer is 5 1/4. The tank originally 5.25 gallons of water.</span>
