The cost of 3 notebooks and 2 pencils is $5.10. At the same prices, the cost of 2 notebooks and 3 pencils is $4.65. What is the
Pepsi [2]

Answer:

$1.95

Step-by-step explanation:

notebook = n

pencil = p

3n + 2p = 5.10

2n + 3p = 4.65

multiply top equation by 2 and bottom by 3

6n + 4p = 10.20

6n +9p = 13.95

subtract bottom equation from the top equation

-5p = -3.75

divide by 5, negatives cancel out

p  = 0.75

sub p into either equation, I chose the original top equation

3n + 2(0.75) = 5.10

3n + 1.50 = 5.10

subtract 1.50 from both sides

3n = 3.60

divide both sides by 3

n = 1.20

p = 0.75

n + p = 1.95 (the fourth option)

Given a sphere with a diameter of 6 cm, find its volume to the nearest whole<br> number.
mezya [45]

Answer:

Volume of the sphere is 1.13\times 10^{-4}m^3

Step-by-step explanation:

It is given diameter of the sphere d = 6 cm = 0.06 m

Radius of the sphere

r=\frac{d}{2}=\frac{0.06}{2}=0.03m

We know that volume of the sphere is given by

V=\frac{4}{3}\pi r^3

Therefore ,

V=\frac{4}{3}\times 3.14\times  0.03^3

=1.13\times 10^{-4}m^3

Therefore volume of the sphere is 1.13\times 10^{-4}m^3
