use symbols to compare the numbers 512 and 521. write the comparison to ways. then explain your thinking
Morgarella [4.7K]

Solution:-  Given numbers to compare are 512 and 521 .

As they are 3 digit numbers

So, we have to compare hundreds place.

But hundreds are equal in both the numbers with digit 5.

Next we have to compare tens place.

Case 1 :- 1 ten is smaller in 512 than 2 tens in 521 .

So we get the result that,

512 is smaller than 521

or <em>  512 < 521</em>

Case 2:-2 tens is greater in 521 than 1 ten in 512 .

So we get the result that,

521 is greater than 512

or  <em> 521 > 512</em>

Javier's parents set an amount of money aside when he was born. They earned 4.5% simple interest on that money each year. When J
solmaris [256]

Answer:

Javier's parents set aside $1500 when he was born

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question, we have that:

E = 1012.50, t = 15, I = 0.045

We have to find P. So

E = P*I*t

1012.50 = P*15*0.045

P = \frac{1012.50}{15*0.045}

P = 1500

PLZ Answer ASAP!!!
Sliva [168]

Answer:

D. x = 3

Step-by-step explanation:

The only way we could get a line of symmetry through this figure is to use a vertical line.  The only way to get symmetry would be to put the vertical line though the point x = 3.  When we do that, we can see that the end points of the base are both one unit away from the line of symmetry.  The end points I'm talking about are the points at the coordinates (2, 4), and (4, 4)
