You invest $500 into an account that collects 1% interest each month. If you add an additional $50 each week, what will the balance of the account be after 5 months?
Answers
Answer:
$1555.91
Step-by-step explanation:
First Month:
You start out with $500.
You add $200 in the first month, and have 700.
Multiply 700 by 1.01, to add the interest and you get 707.
Second Month:
707 + 200 = 907
907 x 1.01 = 916.07
Third Month:
916.07 + 200 = 1116.07
1116.07 x 1.01 = 1127.2307
Fourth Month:
1127.2307 + 200 = 1327.2307
1327.2307 x 1.01 = 1340.503007 (round to .50)
Fifth Month:
1340.50 + 200 = 1540.50
1540.50 x 1.01 = 1555.905
Round to 1555.905 1555.91, and there's your answer. Hope this helps!
The access code for a company's security system consists of four digits. Each digit can be 0 through 9. The company want to issue a different security code to each of its 200 employees. The company also has to re-issue new codes to each employee every month for security purposes. How many access codes are possible if..
Each digit can be used only once and NOT repeated?
Please help someone :(
Answers
Answer:
2 codes are possible
Step-by-step explanation:
4 6
2571
0389
There are only 10 digits and you can only use the digits onces so the answer would be 2 codes are possible.
The number of possible codes will be 5,040.
How to get the possible codes?If each digit can be used only once, then the number of possible access codes is calculated as follows:
The first digit can be any of the 10 digits (0 through 9).
The second digit can be any of the remaining 9 digits (since one digit has already been used).
The third digit can be any of the remaining 8 digits.
The fourth digit can be any of the remaining 7 digits.
Therefore, the total number of possible access codes is:
10 x 9 x 8 x 7 = 5,040
So, there are 5,040 possible access codes if each digit can be used only once and not repeated.
Since there are 200 employees, the company has enough unique codes for each employee for 25 months. After that, the codes will have to be repeated, which may compromise the security of the system.

There are 5 blue blocks, 7 red blocks, 2 yellow blocks, and 12 green blocks. What is the ratio of yellow blocks to total blocks?
Answers
Answer:
2:26.
Step-by-step explanation:
There are 26 blocks total, and compared to the yellow blocks, there are only two. So that would be 2:26.
Answer:
2:26
Step-by-step explanation:
A ratio is just a mathematical way to show a relationship between things. I wrote it with a colon (:), but you can write it as a fraction or words "x to b."
Most of the time in math, the order of how the question is asked doesn't matter. When it's a ratio, it does matter. Because they ask about the yellow blocks first, that has to be the first part of the ratio.
There are 2 yellow blocks.
Next, it asks for the total. That will be the other part. Add all the total blocks together: 5+7+2+12= 26.
There are 26 total blocks.
Technically, we can simplify this down to 1:13, but it's not asking to simplify it, so let's just leave it as 2:26.

Solve the following system:

Answers
Answer:
infinitely many solutions
Step-by-step explanation:
The system of equations :
3x + 2y = 7-4.5x - 3y = -10.5Multiplying Equation 1 times 3 and Equation 2 times 2 :
9x + 6y = 21-9x - 6y = -21Putting the equations in standard form after simplifying :
6y = -9x + 21 ⇒ y = -1.5x + 3.5-6y = 9x - 21 ⇒ y = -1.5x + 3.5As both equations are the same, the system will have infinitely many solutions.

The angle k will be 100 in the triangle KJL and the side HI will be 4.
What is triangle?
A triangle is a plane figure formed by the three sides having sum of the angles 180 degree.
Here in triangle KJL we can see that it is a isosceles triangle So the angle j and angle L will be 40.
Now we can solve
[tex]\angle L + \angle J + \angle K=180\\\\\\40+40+\angle K=180\\\\\\\angle k=180-80\\\\\\\angle k=100[/tex]
Now the side HI in the triangle HGI
We can see that the triangle HGI is the equilateral triangle so the all sides will be equal so
[tex]HI=IG=GH=4\[/tex]
