A student allows 1/10 of her monthly income for books and 1/8 of her monthly income for clothing. If she budgets a total of $300 per month for books and clothing, what is her monthly income, x?
Answers
Answer: 1333.(3)
Step-by-step explanation:
Let her monthly income be x. Then,
(1/10)x + (1/8)x = 300
(4/40)x + (5/40)x = 300
(9/40)x = 300
x = 300 / (9/40)
x = 300*40/9
x = 12000/9
x = 1333 1/3 = 1333.(3)

in which number does the digit 5 have a value that is 10 times as great as the value of the digit 5 in 253,829
Answers
Moving 5 one digit to the left, one number in which the value of digit 5 is 10 times as great as in 253,829 is in 538,290.
What does it mean to move a digit one position to the left?It means that the value of the digit is multiplied by 10.
Hence, moving the digit 5 one position to the left, and appending a zero at the end, generating the number 538,290, the value of digit 5 is 10 times as great as in 253,829.

Answer:

Step-by-step explanation:
open the bracket
1 - 6i - 3 + 4i
1 - 3 + 4i - 6i
-2 - 2i
Answer:
-2 - 2i
Step-by-step explanation:
Complex numberAdd the real numbers (1 and (-3) ) and add the complex numbers [ 4i and (-6i) ]
(1 - 6i) - ( 3 - 4i) = 1 - 6i - 3 + 4i
= 1 -3 - 6i + 4i
= -2 - 2i
We have to open the brackets. To do that Multiply (-1) with (-3) & 4i. Now, complex numbers are (-6i) and 4i. So combine them. 6i and 4i have different signs. So, subtract and the result will have bigger number sign. Here the bigger number sign is negative. So, -6i + 4 i = -2iNow combine real numbers. 1 - 3 = -2based on a survey of 425 master’s programs in business administration, the u. s. news & world report ranked the indiana university kelley business school as the 20th best business program in the country (america’s best graduate schools, 2009). the ranking was based in part on surveys of business school deans and corporate recruiters. each survey respondent was asked to rate the overall academic quality of the master’s program on a scale from 1 “marginal” to 5 “outstanding.” use the sample of responses shown below to compute the weighted mean score for the business school deans and the corporate recruiters. discuss.quality business school corporate assessment deans recruiters 5 44 31 4 66 34 3 60 43 2 10 12 1 0 0
Answers
The deans have a higher weighted mean score for business schools which is 3.8.
What is weighed mean?The weighted arithmetic mean is similar to the conventional arithmetic mean in that certain data points contribute more than others to the final average.
Weighed mean = (weightage x parameter)/no of parameters
The Weighted mean score for deans
= [(5×44)+(4×66)+(3×60)+(2×10)]/(44+66+60+10)
= 684/180
= 3.8
The Mean weigted score of recruiters
= [(5×31)+(4×34)+(3×43)+(2×12)]/(31+34+43+12)
= 444/120
= 3.7
Hence, The deans have a higher weighted mean score for business schools which is 3.8.

Determine the equation of the line passing through the points (-1, 1) and (1, 7).
Write the line in standard form Ax+By=C
Answers
Answer:
[tex]3x + y = -4[/tex]
Step-by-step explanation:
We were given to points on the line we are trying to find, hence we are able to determine the slope/gradient.
[tex]( - 1, \: 1) \: and \: (1, \: 7) \\ slope = \frac{ {y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} } \\ \\ s = \frac{7 - 1}{1 - ( - 1)} \\ s = \frac{6}{2} [/tex]
Slope is equal to 3.
Since we have the value for the slope, we can now use one of the points on the line to determine the equation of the line.
note that the coefficient of x is the slope. In this case the A from the standard form (Ax + By= C) is the slope.
[tex] \\ let \: us \: use \: the \: point \: ( - 1, \: 1) \\ a = 3 \: \: \: \: y = 1 \: \: \: x = - 1\\ ax + by = c \\ 3( - 1) + 1 = c \\ - 3 + 1 = c [/tex]
[tex] - 2 = c \\ therefore \: the \: equation \: of \: the \\ \: line \: is \\ ax + by = c \\ 3x + y = - 4[/tex]

You invested money in two funds. Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $858. This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $867. How much money did you invest in each fund?
Answers
The amount that was invested in the first fund is $8300.
The amount that was invested in the second fund is 3700.
What are the linear equations that represent the question?0.09a + 0.03b = $858 equation 1
0.1a + 0.01b = $867 equation 2
Where:
a = amount invested in the first fund b = amount invested in the second fund How much was invested in the second fund?Multiply equation 2 by 0.9:
0.09a + 0.009b = 780.30 equation 3
Subtract equation 1 from equation 3
0.021b = 77.70
Divide both sides by 0.021
b = $3700
How much was invested in the first fund?
Substitute for b in equation 1: 0.09a + 0.03(3700) = $858
0.09a + 111 = 858
a = (858 - 111) / 0.09
a = $8300
