Answer:

<u>x = √10</u>

Step-by-step explanation:

x² - 10 = 0

x² = 10

<u>x = √10</u>

so x^2-10=0

we add 10 to both sides of the equation  x^2 = 10

then take the square root of both sides of the equation to eliminate the exponent on the left side  x = ± √10

The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10

the result can be shown in multiple forms

Exact Form :x=√10,−√10x=10,-10

Decimal Form: x=3.16227766…,−3.16227766

The aspect ratio​ (length to​ width) of an lcd computer monitor is 5​ : 4. the lcd monitor of a toshiba laptop computer has a pe
jeka57 [31]

Solution:

Formula of perimeter = 2(W+H)

So, 2W + 2H = 32.4         ... (1)

Ratio = 5:4

So, \frac{W}{H} =\frac{5}{4}

4W - 5H = 0         ... (2)

Solve equation (1) and (2).

W = 9.0 and H = 7.2

Use the Pythagorean theorem,

W^{2} + H^{2} = D^{2}

D^{2} = (9.0)^{2}  + (7.2)^{2}

D^{2} = 132.84

D = 11.52

D = 11.5

Hence, the measure of diagonal is 11.5 inches.

Mei Mei invested $1700 in an account that pays 3% interest compounded annually.
algol [13]

Answer:

$2728

Step-by-step explanation:

Use compound interest formula:

A = P(1 + \frac{r}{n})^{nt}

P = 1700, r = 0.03, n = 1, t = 16

Plug in numbers:

A = 1700(1 + \frac{0.03}{1})^{(1)(16)}

Simplify:

A = 1700(1.3)^{16

Use calculator:

A = 2728

The development of the personal budget that convinces parents that one can maintain an independent living is detailed as follows using the 50: 30: 20 rule:

50% for necessities (housing, food, transportation, utilities) $740

30% for luxuries, savings, vacations, entertainment, etc. $461

20% for Emergency Funds and Retirement $335

<h3>What is a personal budget?</h3>

A personal budget is the household budget for a single person for a period.

The personal budget shows an estimate of the person's revenue and expenses over the period.

<h3>Data and Calculations:</h3>

Hourly rate of earnings = $12

Working hours per week = 40 hours

Working hours per month = 160 hours (40 x 4 weeks)

Total monthly earnings = $1,920 ($12 x 160)

Assumed tax rate = 20%

After-tax take-home pay = $1,536 ($1,920 x 1 - 20%)

<h3>Monthly Necessities:</h3>

Rent of apartment = $300

Heating = $40

Water cost = $20

Sewage bill = $10

Food = $300

Transportation = $50

Other costs = $20

Total cost for necessities = $740

Thus, the development of the personal budget shows that one can maintain an independent living from the parents as a single person.
