Answer:

Step-by-step explanation:

Formula

C = 5/9*(F - 32)

Givens

F = 86 deg F

Solution

C = 5/9* (86 - 32)         Combine the right

C = 5/9* (54)                 Divide by 9

C = 5 * 6

C = 30 deg C

A cash register contains $5 bills and $50 bills with a total value of $1060. If there are 32 bills total, then how many of each
kozerog [31]

Answer:

12 5 dollar bills

20 50 dollar bills

Step-by-step explanation:

Let x = number of five dollar bills

Let y = number of fifty dollar bills

We have a total of 32 bills

x+y = 32

The total amount is 1060

5x+50y = 1060

We have 2 equations and 2 unknowns

x+y = 32

5x+50y = 1060

Multiply the first equation by -5 so we can eliminate x

-5x -5y = -5*32

-5x -5y =-160

Add this to the second equation

5x+50y = 1060

-5x -5y =-160

------------------------

45 y    = 900

Divide each side by 45

45y/45 = 900/45

y = 20

There are 20 50 dollar bills

x+y = 32

x+20 = 32

Subtract 20 from each side

x+20-20 = 32-20

x = 12

There are 12 5 dollar bills

rodikova [14]

Answer:

<h2>19,600 J</h2>

Step-by-step explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

We have

PE = 500 × 9.8 × 4

We have the final answer as

<h3>19,600 J</h3>
