Step-by-step explanation:

To find the number of baseball cards each person received we must first find the total parts

That's

2 + 3 = 5

<u>For</u><u> </u><u>Dawn</u>

Dawn's part is 2

We have

2/5 × 60

<h3>= 24 baseball cards</h3>

<u>For Jackson</u>

Jackson's part is 3

That's

3/5 × 60

<h3>= 36 baseball cards</h3>

Hope this helps you

krok68 [10]
Population growth is generally given by an exponential function,

<em>f</em>(<em>x</em>) = <em>a</em>*<em>b</em>^<em>x</em>, where <em>a</em> is the original population, <em>b</em> = 1 + the rate of growth (written as a decimal number), and <em>x</em> is the amount of time.  In our case we have

<em>p</em>(1 + 0.065)<em>^</em>1<em>
</em>= <em>p</em>(1.065) = 1.065<em>p</em>

Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin
Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470       Eqn 1

x = y+14                Eqn 2

Putting value of x from Eqn 2 in Eqn 1

10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330

Dividing both sides by 30

\frac{30y}{30}=\frac{330}{30}\\y=11

Putting y=11 in Eqn 2

x=11+14\\x=25

There are 25 $10 bills and 11 $20 bills.
