There are 900000000 nine-digits numbers and exactly half of them have an even sum of digits (because every number can be paired with another of the opposite parity by changing the last digit).
Answer: 200,000,000.
we have 9 spaces we need to fill in
There are 10 total numbers(0–9)
There are 5 even numbers(0,2,4,6,8)
fill from left to right
u cannot start with 0 so pick another number 2,4,6,8 any of those
4*10^7*5= 20*10^7 = 2*10^8
200,000,000.

What is the equation of the line that passes through the point(6,4) and has a slope of -2/3
Answer:
y=-2/3x+8
Step-by-step explanation:
first, find the y intercept, or b.
write your equation so far: y = -2/3x + b
Now substitute in your given point (6,4)
so now we got: 4 = -2/3(6) + b
which gives you: 4 = -4 + b
Now, we find b.
4 = -4 + b
+4 +4 < isolating b...
8 = b
now put it back in..
y=-2/3x+b
hope this helped luv <3
D») 5. Carlos opens a savings account with a deposit of $1,000. The account earns
interest at a rate of 2% per year. Let A(1) denote the amount of money (in
dollars) that is in the account tyears after the account is opened. The
equation below displays the relationship between A(t) and t.
A(1) = 1,000 + 20+
Carlos will not close his account before $1,500 is present. Which of the
following intervals contains all the possible number of years after opening his
account that Carlos could close it?
Answer: After 25 years
Step-by-step explanation:
You included no intervals as options.
Question however states that Carlos will not close his account before $1,500 is present which means that he will only close this account after the interest has accumulated to $500.
Given that the account makes $20 a year, the number of years it would take to get to $500 is;
= 500/20
= 25 years
Carlos can close the account at any interval after 25 years.

In a chest there are some gold coins. Captain takes half the
coins. Sally takes a fourth of the coins. There are 3 coins left.
How many coins were in the chest at the start?
Answer:
7
Step-by-step explanation:
4+3=7
Answer:
There were 12 gold coins in the chest at the start.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
x = Number of gold coins in a chest
1/2x = Number of gold coins taken by the captain
1/4x = Number of gold coins taken by Sally
3 = Number of gold coins left
2. How many coins were in the chest at the start?
Let's write the following equation to solve for x:
1/2x + 1/4x + 3 = x
2x + x + 12 = 4x (Lowest Common Denominator is 4)
4x - 2x - x = 12 (Like terms)
x = 12
There were 12 gold coins in the chest at the start.
Hope this helps :D

Which equation represents a line that is parallel to the x-axis, is perpendicular to the y-axis, and has a slope of 0?
A.
[tex]y = \frac{4}{5} x + \frac{5}{4} [/tex]
B.
[tex]y = \frac{5}{4} x[/tex]
C.
[tex]y = \frac{4}{5} [/tex]
D.
[tex]x = \frac{5}{4} [/tex]
Answer:
C
Step-by-step explanation:
The equation of a line parallel to the x- axis ( slope of 0 ) and perpendicular to the y- axis has equation
y = c
where c is the value of the y- coordinates the line passes through.
The only equation in this form is
y = [tex]\frac{4}{5}[/tex] → C

Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Answer:
The points (0, 0) and (1, 20) can be used to create the line that represents the situation.
If t is the x-coordinate and r is the y-coordinate, then any point that satisfies the equation r = 20t for t > 0 can be used to graph the line. So, any two points that satisfy the equation, such as (0, 0), (1, 20), (2, 40), (3, 60), (4, 80), (5, 100), and so on, can be used to create the line that represents the situation. The line is the same in each case.

Find the simple interest earned, to the nearest cent, for the principal, interest rate, and time.
$530, 6%, 1 year
The simple interest earned on $530 at 5.5% rate for 1 years is $31.80.
How to calculate simple interest?The formula for simple interest is expressed mathematically as;
I = P × r × t
Where I is interest, P is principal, r is interest rate and t is time period.
Given the data in the question;
Principal P = $530Interest rate r = 6%Time period t = 1 yearInterest I = ?First, convert the rate from percent to a decimal form
Rate r = 6%
Rate r = 6/100
Rate r = 0.06
To determine the simple interest earned, plug the given values into the simple interest formula and solve for I.
I = P × r × t
I = $530 × 0.06 × 1
I = $530 × 0.06
I = $31.80
Therefore, the simple interest accumulated after 1 years is $31.80.
