Missing Details

Quarters ≡ Dimes ≡ Nickels ≡ Pennies

23 ≡ 29 ≡ 17 ≡ 38

Answer:

$P(Q\ or\ P) = 0.5701$

Step-by-step explanation:

Given

$Quarters = 23$

$Dimes = 29$

$Nickels = 17$

$Pennies = 38$

First, we calculate total number of coins

$Total = 23 + 29 + 17 + 38$

$Total = 107$

The probability of obtaining quarter (Q) of penny (P) is:

$P(Q\ or\ P) = P(Quarters) + P(Pennies)$

$P(Q\ or\ P) = \frac{n(Quarters)}{Total} + \frac{n(Pennies)}{Total}$

Take LCM

$P(Q\ or\ P) = \frac{n(Quarters) + n(Pennies)}{Total}$

$P(Q\ or\ P) = \frac{23 + 38}{107}$

$P(Q\ or\ P) = \frac{61}{107}$

$P(Q\ or\ P) = 0.5701$

The given figure is a solid object formed by a cylinder and a hemisphere. If the total length of that solid object is 64 cm and

VARVARA [1.3K]

The total surface area of the solid object is 2660.925 square cm the answer is 2660.925 square cm.

<h3>What is a cylinder?</h3>

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

$\rm V = \pi r^2 h$

The surface area of the

= surface area of half sphere + surface area of the cylinder - surface area

of one circular base

The radius r = (64-50)/2 = 7 cm

= (1/2)[4π(7)²] + 2π(7)(50) + 2π(7)² - π(7)²

= (1/2)[615.75] + 2506.99 - 153.94

= 307.875 + 2506.99 - 153.94

= 2660.925 square cm

Thus, the total surface area of the solid object is 2660.925 square cm the answer is 2660.925 square cm.
