Answer:

95$

Step-by-step explanation:

Alli sells 5 bars, for each bar she earnd 5$ so she earns 5*5=25$

Janet sells 7 mugs, and for every mug she earns 10$ (twice then Alli), so she earns 7*10=70$

Together: 25+70=95$

Answer:

Step-by-step explanation:

For every bar of soap that Ali sells, she earns $5. For every mug that Janet sells, she earns twice as much as Ali. This means that the amount that Janet earns for each mug she sells is 5 × 2 = $10

Ali sells 5 bars of soap. This means that the total amount that Ali earned is 5 × 5 = $25

Janet sells 7 mugs. This means that the total amount that Janet earned is 7 × 10 = $70

Therefore, the amount that they earned altogether is

25 + 70 = $95

Am I dealing with harmonic stuff (trig)?
pochemuha

You just need to solve for when y=0:

\dfrac{\cos8t-9\sin8t}4=0\implies\cos8t-9\sin8t=0

\implies\cos8t=9\sin8t

\implies\dfrac19=\dfrac{\sin8t}{\cos8t}=\tan8t

\implies8t=\tan^{-1}\dfrac19+n\pi

\implies t=\dfrac18\tan^{-1}\dfrac19+\dfrac{n\pi}8

where n is any integer. We only care about when 0\le t\le1, which happens for n\in\{0,1,2\}.

t=\dfrac18\tan^{-1}\dfrac19\approx0.01

t=\dfrac18\tan^{-1}\dfrac19+\dfrac\pi8\approx0.41

t=\dfrac18\tan^{-1}\dfrac19+\dfrac\pi4\approx0.80

3. The regression equation y = –0.414x + 106.55 approximates the percent of people in an audience who finish watching a document
BartSMP [9]

Answer:

The answer is 78%

Step-by-step explanation:

Step 1: The given regression equation y = -0.414x + 106.55

Step 2: The length of the film  = 70 minutes

Step 3: Plug in x = 70 in the given equation and find the value of y.

y = -0.414 (70) + 106.55

y = -28.98 + 106.55

y = 77.57

Y = 78%

Hope you will understand. :)

A principal of $2900 is invested at 4.25% interest, compounded annually. How much will the investment be worth after 7 years?
olga2289 [7]

Let S = Sum after 13 years

     So = amount invested

     t = time in years

     i = annual interest rate = .0325

The S = So(1+i)t = $2,200(1.0325)13 = $3,334.21
