The rodriguez family dined at a restaurant. Their bill came up to $119, but they also have to pay a 9% tax and they plan to leav

ladessa [460]

Answer:

The amount is $155.89

Step-by-step explanation:

To find the cost of the meal, find the tax and tip. You can find each by multiplying the amount of the meal by the percentages.

$119 * 9% = 10.71

$119 * 22% = 26.18

Now we can add all three together.

119 + 10.71 + 26.18 = 155.89

A bacteria culture starts with 100 bacteria and doubles in size every half hour.

taurus [48]

Answer:

y=25600

y=100(2)^{2t}

y=252

Step-by-step explanation:

A bacteria culture starts with 100 bacteria and doubles in size every half hour.

$y=100(2)^{2x}$

where x represents the number of hours

(a) t= 4 hours

Plug in 4 for t and find out the number of bacteria y

$y=100(2)^{2 \cdot 4}\\y=25600$

25600 bacteria

$y=100(2)^{2t}$

convert 40 seconds into hour

40 divide by 60 =2/3

$y=100(2)^{2\frac{2}{3} }\\y=100(2)^{\frac{4}{3} }\\\\y=252$

The graph is attached below
