We know, a number is divisible by 9 if the sum of digits is also divisible by 9.
Also, since A is an digit, so A is in between 0 to 9.
2+A+5+A+0+A+2 = 3A + 9
3A + 9 should be divisible by 9.
3A + 9 = 9n
A = (9n -9)/3
For n= 1 :
A = 0
For n=2 :
A = 3
For n= 3 :
A = 9
After this A > 9 which is not accepted.
Therefore, the digit A can be 0, 3 and 9 .
Hence, this is the required solution.
The digit A that makes 2A5A0A2 to be divisible by 99 is;
A = 3
From study of divisibility of single digit numbers, it was discovered that a number can be divisible by 9 or a multiple of 9 provided the sum of digits is also divisible by 9.We are given the number 2A5A0A2
A is a single digit and as such will be between 0 and 9.
Thus, using the principle above;
2 + A + 5 + A + 0 + A + 2 = 3A + 9
Applying the principle;3A + 9 must be divisible by 9.
Thus;
3A + 9 = 9x
A = (9x - 9)/3
When x = 1;
A = 0
When x = 2;
A = 3
When x = 3;
A = 9
Since A is a single digit, then it means that x cannot be more than 4 as any value of x more than 4 will yield a value of A that is not a single digit.Now, when we place either the value of 0, 3 or 9 for A into the given number, the only one that yields a number that is divisible by 99 is A = 3

An object is moving at a speed of 230 feet per week. Express this speed in inches per
minute. Round your answer to the nearest hundredth.
Answer:
Step-by-step explanation:
0.27 inches per minute....
An object is moving at a speed of 230 feet per week. This speed in inches per minute will be 0.27.
We know ,
1 feet = 12 inches and
1 week= 7days = 24×7 hours = 24×7×60 min.
= 10080 min.
Now, we just need to be careful with our multiplication and division. So we are going to have 230 times 12 on top divided by 24 times 7 times 60 i.e., 10,080 on bottom.
230 feet per week in inches per min = 230×12/10,080.
After evaluating and rounding up to 2 decimal places or the hundredth place , we will get our answer i.e., 0.27 inches/min.

Function n has an x-intercept at (4,0), which statement must be true about D, the discriminant of function h?
OA. D< 0
OB. DO
OC. DO
OD. D = 0
The statement which must be true about D, the discriminant of function h is D =0 hence, option (D) must be correct.
What is the discriminant of function?When working with quadratic equations, the discriminant is commonly calculated to investigate the kind of roots. Even though it is difficult to ascertain a discriminant for any polynomial, there exist methods for collecting the discriminant of cubic and quadratic equations that reduce our approach.
The discriminant function gives us an idea about the nature of the solution whether it is real or not if real then how much will be the solution?
If D > 0 then there will be 2 real solutions.
If D = 0 then there will be 1 real solution.
If D < 0 then there will be 2 imaginary solutions.
Given that function, h has an interception it means there will be a real solution. Hence, D = 0 will be the correct answer.

This table shows the input and output values for a linear function f(x).
What is the difference of outputs for any two inputs that are one value apart?
−30
−25
1
20
Answer:
-25
Step-by-step explanation:
The following are x-values (inputs) and their y-values (outputs) that are one value apart:
(Input, output)
✅(-2, 20) and (-1, -5)
Difference between their outputs = -5 - 20 = -25
✅(-1, -5) and (0, -30)
Difference between their outputs = -30 -(-5) = -25
✅(0, -30) and (1, -55)
Difference between their outputs = -55 -(-30) = -25
✅(1, -55) and (2, -80)
Difference between their outputs = -80 -(-55) = -25
As we can see the difference of outputs for any two inputs that are one value apart = -25

Ken has an investment account which compounds interest continuously at a rate of 3.4%. After 4 years, he has $4400 in the account. How much money did he initially place in the account? Round your answer to the nearest dollar. Do NOT round until you have calculated the final answer.
Answer:
$6617
Step-by-step explanation:
Use the formula for calculating compound interest A=P0ert where A is the unknown, P0=4400, r=0.034, and t=12. Substitute the values into the formula and simplify.
A=4400e0.034⋅12
A=4400e0.408
A=4400(1.503...)

While negotiating to have a new facility built in Sheboygan, Wisconsin, a company promises to hire 700 workers initially, and then hire an additional 50 workers every four months. Write a linear equation that describes the number of employees (y) in terms of
the number of years after the initial hires are made (x).
What is the correct equation?
Answer:
y= 700 + 150x
Step-by-step explanation:
Since they hire 50 employees every 4 months, that's 150 new employees per year, plus the initial 700. So, you multiply 150 by the number of years, add 700 to that, and it equals y.
