[tex]\frac{-13 - 11i}{29}[/tex]
Step-by-step explanation:
You need to multiply the numerator and denominator by the conjugate of
2 + 5i, which is 2 - 5i
So, [tex]\frac{(1 - 3i)(2 - 5i)}{(2 + 5i)(2 - 5i)} = \frac{2 - 11i - 15}{4 +25} = \frac{-13 - 11i}{29}[/tex]
In a test consisting of 12 questions, each student gets a score of +23 for every correct answer and −13 for every incorrect answer. Each question must be answered. Ram gets 7 correct and 5 incorrect answers. What's his score?
Answer:
96 scores
Step-by-step explanation:
Score for each correct answer = +23
Score for each incorrect answer = [tex]-13[/tex]
Each question must be answered such that Ram gets 7 correct and 5 incorrect answers.
Number of correct answers [tex]=7[/tex]
Number of incorrect answers [tex]=5[/tex]
Therefore,
Ram's score [tex]=7(23)+5(-13)=161-65=96[/tex]
John bought a pack of 18 cards for $2.99. About how much did each card cost?
Answer:
0.166
Step-by-step explanation:
Bought 18 cards for $2.99, so you can write it like this:
18 = 2.99
Since you want to find the value of one card, u could write that like this:
1 = x (where x is the unknown value of 1 card)
To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.
So 2.99/18 = 0.166
therefore x = 0.166
So you can say that each card costs about 17 c

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap costs $1.00 and the chicken wrap costs $1.50. Today they made $135.50 from the 117 wraps sold. How many of the wraps sold were vegetarian?
Answer:
Number of vegetarian wraps = 80
Number of chicken wraps = 37
Step-by-step explanation:
Let
Number of vegetarian wraps = x
Number of chicken wraps = y
x + y = 117 (1)
x + 1.5y = 135.50 (2)
Subtract (1) from (2) to eliminate x
1.50y - y = 135.50 - 117
0.50y = 18.50
y = 18.50/0.50
y = 37
Substitute y = 37 into (1)
x + y = 117 (1)
x + 37 = 117
x = 117 - 37
x = 80
Number of vegetarian wraps = 80
Number of chicken wraps = 37

How many gallons of red paint should they mix with 1 gallon of white paint?
Let parts be represented as x
Hence:
Red : white
4 : 5
4/5 = x/ 1
We cross Multiply
5x = 4
x = 4/5
x = 0.8 gallons of red paint or 4/5 gallons of red paint

QUESTION 6 of 10: You expect your expenses to grow non-linearly over time by the following formula: expenses = 4,000 + 20,000 x (1.5)
where t is the number of months in business. What are your estimated expenses after 6 months ?
a) $231,813
b) $242,131
c) $277,961
d) $282,918
Answer:
$231,813
Step-by-step explanation:
The estimated expenses after 6 months is $231,812.5
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
Expense = 4,000 + 20,000 x [tex](1.5)^t[/tex]
Now, for t= 6 months
Expense = 4,000 + 20,000 x [tex](1.5)^6[/tex]
Expense = 4,000 + 20,000 x 11.390625
Expense = 4,000 + 2,27,812.5
Expense = 231,812.5
Hence, The estimated expenses after 6 months is $231,812.5.

You need to have a password with 6 letters followed by 3 odd digits between 0 and 9
, inclusive. If the characters and digits cannot be used more than once, how many choices do you have for your password?
Answer:
9,945,936,000.
Step-by-step explanation:
This is the number of permutations of 6 letters from 26 multiplied by number of permutations of 3 odd digits between 0 and 9.
The total number of odd digits between 0 and 9 are 1,3,5,7,9 = 5.
So the number of choices are
26P6 * 5P3.
= 26!/(26-6)! * 5!/ 2!
= 26!/20! * 5!/2!
= 165765600 * 60
= 9945936000.

What are the coordinates of the x-intercept for the line that goes through points (3, 2) and (3, 6) ?
Answer:
x-intercept for the line is 3Step-by-step explanation:
Given the coordinate points (3, 2) and (3, 6), to get the x intercept, we need to first get the equation of the line passing through the points
Form the coordinate, we can see that the line passes through the points x = 3 on both coordinates. This shows that the line is a horizontal line cutting the x axis at x =3. Hence the x-intercept for the line will be 3

The coldest temperature in New York City was -15 on February 9th 1934, The next day the temperature rose 42 degrees. Write an expression for the temperature on February 10th
Answer:
27°C
Step-by-step explanation:
The temperature on February 9th 1934 = -15°C
The next day the temperature rose 42 degrees.
We need to find an expression for the temperature on February 10th.
February 10th temperature = -15 + 42
= 27°C
So, the temperature on February 10th is 27°C.
