Two spheres have volumes of 8π cm3 and 64π cm3. if the surface area of the smaller sphere is 16π cm2, what is the surface area o
klemol [59]

The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

The volume of the larger sphere = 64π cm³

let us take the radius of the larger sphere r

So, 4/3*π*r³ =64π

r³=48

r=2∛6

<h3>What is the surface area of a sphere?</h3>

The surface area of a sphere with radius r is 4πr².

So, the surface area of the larger sphere = 4π(2∛6)²

The surface area of the larger sphere = 16π∛36

Hence, The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

When a machine is adjusted properly, 50% of the items it produces are good and 50% are bad. However, the machine is improperly a
Marta_Voda [28]

Answer:

Step-by-step explanation:

Probability of good given properly adjusted  P(G/P) = .5

Probability of bad given properly adjusted  P(B/P) = .5

Probability of inappropriately adjusted P(I ) = .1

Probability of properly adjusted P(P) = .4

Probability of good given inappropriately adjusted P( G/I ) = .25

Probability of bad given inappropriately adjusted  P(B/I ) = .75

P( G ) = P(G/P) x  P(P) + P( G/I ) x P(I )

P(P/G) = P(G/P) x  P(P)    /     P(G/P) x  P(P) + P( G/I ) x P(I )

=   .5 x .4  / .5 x .4 + .25 x .1

= .20 / .20 + .025

.20 / .225

20 / 22.5

= 4 / 4.5 .

= 8 / 9 .

If 8 cents are needed to buy 10 pebbles, how many dollars are needed to buy 205 pebbles?
stira [4]

Answer:

Hello There!!

Step-by-step explanation:

If 8 cents=10 pebbles then do 205 divided by 10 which is 20.5 . So, 8×20.5=164 dollars.

(8×20.5=164) 8 cents=10 (10×20.5=205)

164 dollars=205

Therefore,the answer is 164 dollars.

hope this helps,have a great day!!
