To find how many stacks of quarters there are we must divide 7,560 by 4.

7,560 / 4 = 1,890

There are 1,890 4-inch stacks. To find how many quarters are in all the stacks, we multiple 1,890 by 58.

1,890 * 58 = 102,060

The arch is 102,060 quarters high

Sum of 2 numbers is 42, and their difference is 8. What are the numbers?​
Tems11 [23]

Answer:

25 , 17

Step-by-step explanation:

Let the unknown two numbers be x & y.

According to the question,

Sum of 2 numbers is 42.

x + y = 42  ⇒ ( 1 )

Their difference is 8.

x - y = 8 ⇒ ( 2 )

First let us find the value of x.

( 1 ) + ( 2 )

x + y + x - y = 42 + 8

2x = 50

Divide both sides by 2.

x = 25

And now let us find the value of y.

x + y = 42

25 + y = 42

y = 42 - 25

y = 17

Therefore, the two numbers are 25 , 17

Hope this helps you :-)

Let me know if you have any other questions :-)

The formula I = PRT is used to calculate the amount of simple Teresa earned. Solve this formula for T
Dmitrij [34]

To solve this formula for T, divide both sides of the original equation by PR:

  I         PRT

------ = ---------   =>    T = I / (PR)

PR        PR

Please note:  Because the formula I = PRT involves neither addition nor subtraction, the final formula for T cannot involve either addition nor subtraction.  That leaves:

T = I P/R

T= IPR

The second formula here is incorrect; we cannot solve I = PRT for T simply by rearranging the order of the variables.  This leaves T = I P/R as a possible answer, but this answer does not agree with my   T = I / (PR).  Please double check to ensure that you have copied down the four possible answers correctly.
