No, a line plot does not show individual data. It shows two things...for example how many months and the interest rate rising

Solve the quadratic equation by completing the square x^2+5x-3=0

PIT_PIT [208]

${\tt{x = \frac{ -b± \sqrt{ {b}^{2} - 4ac } }{2a} }}$

${\tt{ x = \frac{ - 5±\sqrt{{5}^{2} - 4 \times 1 \times ( - 3)} }{2 \times 1} }}$

${\tt{x = \frac{ - 5±\sqrt{25 + 12} }{2} }}$

${\tt{x = \frac{ - 5 ±\sqrt{37} }{2} }}$

${\tt{x = \frac{ - 5 + \sqrt{37} }{2} }}$

${\tt{x = \frac{ - 5 - \sqrt{37} }{2} }}$

Answer:

Therefore he invested $60,000 at 9% per year and $(210,000-60,000)=$150,000 at 4% per year.

Step-by-step explanation:

Given John plans to invest $210,000 in two different funds. He projects that the moderately high risk investments should return, overtime 9% per year,while low risk investments should return about 4% per year.

He wants a supplemental income of$11,400 a year.

Let , he invested $x at 9% per year and $(210,000-x) at 4% per year.

$interest=\frac{prt}{100}$ p = principle , r = rate of interest and t = time

The interest earns at 9% per year= $\frac{x\times 9\times 1}{100}$

The interest earns at 4% per year= $\frac{(210,00-x)\times 4 \times 1}{100}$

According to the problem,

$\frac{x\times 9\times 1}{100}+\frac{(210,00-x)\times 4 \times 1}{100}= 11400$

$\Leftrightarrow 9x+840000-4x=11400 \times 100$

$\Leftrightarrow 5x=1140000-840000$

$\Leftrightarrow x=\frac{300000}{5}$

$\Leftrightarrow x=60,000$

Therefore he invested $60,000 at 9% per year and $(210,000-60,000)=$150,000 at 4% per year.

What is five and five eighths plus 11 and five eighths

mihalych1998 [28]

To add mixed numbers like you have here, you first have to convert them into fractions.

To do this, multiply the whole number part of the mixed number by the denominator, and add that value to the numerator.

So, 5 5/8 would become 45/8, because 5 x 8 = 40, and 40 + 5 = 45.
Likewise, 11 5/8 would become 93/8, because 11 x 8 = 88, and 88 + 5 = 93.
This gives us 45/8 + 93/8.

Now, to add the fractions. The two fractions have the same denominator already, so it is easy to add them. Simply add the numerators and keep the denominator the same.
The result of this is 143/8.

To simplify this to mixed number form, divide the numerator by the denominator. This results in 17.875. This means that 17 is your whole number part of the mixed number.
To find out how many eighths you'll have, multiply the 17 you just got by the denominator (8), and subtract the result from your large numerator. 17 x 8 = 136, and 143 - 136 = 7.

Your final result is 17 and 7/8.
