Answer:
$12.00
Step-by-step explanation:
To find the sales tax, we take the price and multiply by the tax rate
tax = price * tax rate
.72 = price * 6%
Changing the percent to a decimal
.72 = price *.06
Dividing each side by .06
.72/.06 = price*.06/.06
12 = price
The price is $12.00
Hello! Here is your answer!
Mean: the mean is the number's all added up and then divided by the number of number's in the equation,
Example:
24 58 93 44 56 Now first we add 24 = 58 = 82 82 + 93 = 257 257 + 44 =
301 301 + 56 = 357 Now we divide our number by the amount of number's
listed "24 58 93 44 56" 357 ÷ 5 = 71.4! And that is the mean,
Mode: Now the mode is the most used number we need to find that to get our answer,
Example: 28 34 58 28 34 53 24 28 Now as you can see there is two 34's one 58 one 53 one 24 and three 28's so the mode is 28!,
Median: The median is the middle number if there is none it would be the half of the two middle number's,
Example: 0 10 20 30 40 50 60 70 80 90 100 The median is 50 to get it simply divide 100 by 2 so the median is once again 50,
Further example: To get the median when there is no middle number 20 35 45 60 80 you would simply get the number between 35 and 45 so the median would be 40,
Range: To find the range you must subtract the highest number by the lowest number
Example: 41 56 58 55 23 63 now we find the highest and lowest number 23 and 63 so we subtract 63 by 23 63 - 23 = 40 so the range is 40. Hope this helps you! :)
Answer:
B. The system has no solution.
Step-by-step explanation:
[12x + 7y] = (20)
[12x + 7y] = (11)
The numbers in (parentheses) are both different while the numbers in the [brackets] are the same.
Answer: Y = 4, X=4 (4,4)
Step-by-step explanation: You must multiply both equations so the leading coefficient cancels out. I’m multiplying both equations by both coefficients so I multiply the entire first equation by -2 so the first equation will be the negative coefficient and the second equation will be multiplied by positive 9 so the negative and positive equations cancel out.
STEPS IN MATH:
1. (9x-8y=4) -2 = -18x + 16y = -8
(2x-3y=-4)9 = 18x-27y= -36
2. ADD THESE EQUATIONS TOGETHER NOW
-18x+16y=-8
+ 18x-27y=-36
0-11y= -44
-11y=-44
DIVIDE -44 by -11y
The final answer is Y= 4
NOW pick an equation to plug in y to, any equation works
I chose the first one, so 9x-8(4)=4
9x-32=4
9x=36
x=4
Answer:
The correct option is;
C. The rate at which the account is increasing
Step-by-step explanation:
The given parameters are;
The rate at which the compound interest on the savings account is compounded = quarterly
The expression given by her banker to find the amount in the account after t years = 4,200(1.05)^(4t)
Therefore, the 1.05 = The rate at which the account is increasing
