Sierra left $4.50 as a tip for a waiter. THis was 18% of the bull before the tip, How much was her total bill before the tip?

andreyandreev [35.5K]

let's say the bill without the tip is "x" amount, so that'd be the 100% of the bill, but we also know that 4.50 is the 18% of "x".

so if 4.50 is the 18% of "x", how much is "x"?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 4.50&18\\ x&100 \end{array}\implies \cfrac{4.5}{x}=\cfrac{18}{100}\implies 450=18x \\\\\\ \cfrac{450}{18}=x\implies 25=x$

Please help on this,

If there are 50 teens in the program and 34% of them have two siblings, then we need to multiply 50 by 0.34 to find 34 percent of 50. 50*0.34 = 17. Therefore, there are 17 teens who have two siblings.

Find the linear approximation for f(x) = 12x3 + 3x2 + x + 2 at x= 1.

Alchen [17]

Answer:

y = 43x − 25

Step-by-step explanation:

Evaluate the function at x=1:

f(x) = 12x³ + 3x² + x + 2

f(1) = 12 + 3 + 1 + 2

f(1) = 18

Find the slope of the tangent line at x=1:

f'(x) = 36x² + 6x + 1

f'(1) = 36 + 6 + 1

f'(1) = 43

Point-slope form:

y − y₀ = m (x − x₀)

y − 18 = 43 (x − 1)

Convert to slope-intercept form:

y − 18 = 43x − 43

y = 43x − 25

Tamara invests $8000 in two different accounts. The first account has a simple interest rate of 3% and the second account has a

34kurt

Let Tamara invests amount $X$ in 3% account. She invests $8000-X$ in 2% account.

The interest after t years is given by

$I=Prt$ . After 1 year the two interests are equal, that is

$X(\frac{3}{100}) (1)=(8000-X)(\frac{2}{100}) (1)\\ 3X=2(8000-X)\\ 5X=16000\\ X=3200$

Thus, Tamara has to invest $\$3200$ in 3% account and $\$8000-\$3200=\$4800$ in 2% account.
