Carlos, Julio and Ricky were born in consecutive years Carlos was the oldest of the three and Ricky was the youngest. In 1990, after their birthday, the sum of their ages was 129. In what years were they born?
Answer:
Carlos born in 1944
Julio born in 1945
Ricky born in 1946
Step-by-step explanation:
x = Carlos age
x+1 = Julio age
x+2 = Ricky age
x + x+1 + x+2 = 129
3x + 3 = 129
3x = 126
x = 42 (Carlos age)
x+1 = 43 (Julio age)
x+2 = 44 (Ricky age)
1990 - 42 = 1944 (year Carlos born)
1990 - 43 = 1945 (year Julio born)
1990 - 44 = 1946 (year Ricky born)

Step-by-step explanation:
Tony's Tires has shown growth over the last month that follows the
equation Sales = 4(Day of the month) +16. On what day of the month will
Tony's Tires double its first day sales?
Answer:
Step-by-step explanation:
The sales will double on the 6th day of the month
The equation sales for last month = 4(day of the month) + 16
let
x = day of the month
The day of the month could be 1, 2, 3, 4, 5, 6, 7, 8...…31. The numbers represents the first, second, third ,...… thirty first day.
Sales = 4x + 16
From the equation, on the first day his sales will be :
sales = 4(1) + 16 = 20 units
The double of 20 units is 40 units. Therefore, the day of the month which the sales will double can be calculated below
40 = 4x + 16
40 - 16 = 4x
4x = 24
x = 24 / 4
x = 6
it will double on the 6th day.

Answer: 43 ft = 14.333333 yd/and/or/43 ft = 14 yd 1 ft
Step-by-step explanation:
To convert a foot measurement to a yard measurement, divide the length by the conversion ratio.Since one yard is equal to 3 feet, you can use this simple formula to convert:
yards = feet ÷ 3
The length in yards is equal to the feet divided by 3.
Answer:14.3333 yards equals 43 feet 1 foot is equivalent to .333 yards

4a. In a book store, for every 9 books sold, 13 magazines were sold. If they had a 572 sales, how many of the sales were for books?
Answer:
234 books.
Step-by-step explanation:
You need to set up a proportion. Be careful to note what it looks like and the explanation that follows.
9 books 13 magazines
======= = ===========
x 572 - x Cross multiply
What you want is the number of book sales from the proportion.
However all you have is the ratio of books to magazines. So you have to set up the total sales to magazines, which is a bit awkward. 572 - x is the number of magazine sales.
9*(572 - x) = 13x Remove the brackets on the left.
5148- 9x = 13x Add 9x to both sides.
5148 = 13x + 9x Transpose and add the right.
22x = 5148 Divide by 22
x = 5148/22
x = 234
234 books were sold.

Private colleges and universities rely on money contributed by individuals and corporations for their operating expenses. Much of this money is put into a fund called an endowment, and the college spends only the interest earned by the fund. A recent survey of 8 private colleges in the United States revealed the following endowments (in millions of dollars): 60.2, 47.0, 235.1, 490.0, 122.6, 177.5, 95.4, and 220.0. What value will be used as the point estimate for the mean endowment of all private colleges in the United States?
Answer:
The value will be used as the point estimate for the mean endowment of all private colleges in the United States is of 180.975 millions of dollars.
Step-by-step explanation:
When we have a sample, the mean of the sample is used as the point estimate for the mean of the entire population.
What value will be used as the point estimate for the mean endowment of all private colleges in the United States?
We have to find the mean of the 8 colleges. So
[tex]M = \frac{60.2 + 47.0 + 235.1 + 490.0 + 122.6 + 177.5 + 95.4 + 220.0}{8} = 180.975[/tex]

The total profit function, P(x), for a company producing x thousand units is given by P(x)=−2x²+38x−120. Find the values of x for which the company makes a profit. [Hint: The company makes a profit when P(x)>0.] Explain and justify your answer.
Answer:
4 < x < 15.
Step-by-step explanation:
Solve -2x^2 + 38x -120 = 0 This gives x = 4 and x = 15. So the company makes a profit when the range of x is greater than 4 and less than 15. The graph of function is a flipped U which pass through x axis at 4 and x = 15. Above the x-axis is the area of profit.

Using the same triangle as above, provide a value for the measure of angle A. Use this value, along with the values you have provided in question 3, to calculate the length of side c and the measure of angle B. The value of A should be between 20 and 70 and cannot be the same as angle C.
Answer:
Step-by-step explanation:
Since the triangle is a right triangle, we know angle B is 90
Then, we know A and C have to make 90 to
so if A has to be between 20 and 70, we can pick 21
as long as A and C make 90, if A is 21, then C is 69
since 21 + 69 = 90
Since it's a right triangle, we can use pythagoran theorem to find c
a² + b² = c²
c = [tex]\sqrt{a^{2} + b^{2} }[/tex]
then you put in the numbers from question 3 (you didn't say what numbers those have to be) and you can find out whats c
What is the value of 2a-b
Answer:
The answer is 13.
Step-by-step explanation:
(b) Find the value of 2a + b: Remember that 2a means 2 × a. Replacing a by 4 and b by 7 gives 2×4 + 7.
Two possible values for 2a - b are 4i√2 and -4i√2, where 'i' is the imaginary unit.
To find the value of 2a - b, we need to eliminate 'b' from the two equations given.
Given equations:
1. 2a + b = 4
2. ab = -3
Let's solve for 'a' and 'b' using these equations.
Step 1: Solve for 'b' in terms of 'a' from equation (1).
2a + b = 4
b = 4 - 2a
Step 2: Substitute the value of 'b' from step 1 into equation (2).
a(4 - 2a) = -3
[tex]4a - 2a^2 = -3[/tex]
Step 3: Rearrange the equation to a quadratic form:
[tex]2a^2 - 4a + 3 = 0[/tex]
Step 4: Solve the quadratic equation for 'a'. You can use the quadratic formula:
a = [ -(-4) ± √([tex](-4)^2[/tex] - 4*2*3) ] / (2*2)
a = [ 4 ± √(16 - 24) ] / 4
a = [ 4 ± √(-8) ] / 4
a = [ 4 ± 2i√2 ] / 4
a = 1 ± i√2
Now we have two possible values for 'a': a = 1 + i√2 and a = 1 - i√2, where 'i' is the imaginary unit (√(-1)).
Step 5: Find the corresponding values of 'b' using the equation b = 4 - 2a.
For a = 1 + i√2:
b = 4 - 2(1 + i√2) = 4 - 2 - 2i√2 = 2 - 2i√2
For a = 1 - i√2:
b = 4 - 2(1 - i√2) = 4 - 2 + 2i√2 = 2 + 2i√2
Now we have two sets of values for 'a' and 'b':
1. a = 1 + i√2, b = 2 - 2i√2
2. a = 1 - i√2, b = 2 + 2i√2
Step 6: Calculate the value of 2a - b for each set of values:
For a = 1 + i√2, b = 2 - 2i√2:
2a - b = 2(1 + i√2) - (2 - 2i√2)
= 2 + 2i√2 - 2 + 2i√2
= 4i√2
For a = 1 - i√2, b = 2 + 2i√2:
2a - b = 2(1 - i√2) - (2 + 2i√2)
= 2 - 2i√2 - 2 - 2i√2
= -4i√2
So, the two possible values for 2a - b are 4i√2 and -4i√2, where 'i' is the imaginary unit.

Rationalize the denominator 18/3root2+1
Answer:
[tex]\dfrac{18(3\sqrt2-1)}{17}[/tex]
Step-by-step explanation:
The given expression is :
[tex]x=\dfrac{18}{3\sqrt2+1}[/tex]
We need to rationalize the denominator.
Multiplying and dividing both sides by [tex]3\sqrt2+1[/tex] as follows :
[tex]x=\dfrac{18}{3\sqrt2+1}\times \dfrac{3\sqrt2-1}{3\sqrt2-1}\\\\=\dfrac{18(3\sqrt2-1)}{(3\sqrt2)^2-1}\\\\=\dfrac{18(3\sqrt2-1)}{(18-1}\\\\=\dfrac{18(3\sqrt2-1)}{17}[/tex]
So, the answer is [tex]\dfrac{18(3\sqrt2-1)}{17}[/tex].

Triangle Inequalities help please
Answer:
No, you can't
Step-by-step explanation:
Given
[tex]Side\ 1 =4[/tex]
[tex]Side\ 2 =9[/tex]
Required
Is a perimeter of 26 possible?
First, calculate the possible side 3
[tex]Side\ 3 = Perimeter - Side\ 1 - Side\ 2[/tex]
[tex]Side\ 3 = 26 - 4 - 9[/tex]
[tex]Side\ 3 = 13[/tex]
Triangle inequalities states that:
Sum of two sides > the third side
So:
[tex]4 + 9 > 13[/tex] --- False
[tex]13 + 9 > 4[/tex] --- True
[tex]4 + 13>9[/tex] ---- True
Since one of the inequalities is false, then a perimeter of 16 is not possible
