Talja [164]

Answer:

Each person will get 5.34 ounces of soda.

Step-by-step explanation:

In order to find out how many ounces of soda each person gets we need to take the total amount of soda Magalie brought to the party and divide it by the number of people that will drink the soda. In this case we have:

amount per person = 48/9 = 5.34 ounces

Each person will get 5.34 ounces of soda.

Which of the following is equivalent to the polynomial given below?
Marizza181 [45]

Answer:

(x+(3+\sqrt{11}i)) (x+(3-\sqrt{11}i))

Step-by-step explanation:

The first step to this problem is to look at the key features of the initial expression given to us. Namely, the middle term.

Notice that it is just +6x. This indicates that the square root terms cancel out, meaning that their signs need to be opposite, but the threes need to have the same, positive sign. This indicates that our answer is option C, but you should always double check by multiplying the expression out to confirm. Here are the steps:

(x+(3+\sqrt{11}i)) (x+(3-\sqrt{11}i))

x^{2} +(3+\sqrt{11}i)x+(3-\sqrt{11}i)x+(3+\sqrt{11}i)(3-\sqrt{11}i)x^{2}+3x+\sqrt{11}ix+3x-\sqrt{11}ix+9+3\sqrt{11}i-3\sqrt{11}i-(\sqrt{11})^{2}(i^{2})x^{2}+6x+9-(11)(-1)

x^{2}+6x+9+11

x^{2}+6x+20

Therefore as we suspected, the answer is C.

Aaron is staying at a hotel that charges $99.95 per night plus tax for a room. A tax of 7% is applied to the room rate, and an a
Serjik [45]

Answer: $543.7325

Step-by-step explanation:

room rate = $99.95 / night

Tax fee = 7% of room rate

Therefore, tax fee = 7% of $99.95

Tax fee = 0.07 × $99.95

Room charge =[$99.95 + 0.07($99.95)]

Room charge = 1.07($99.95) per night

Additional onetime untaxed fee = $9

Therefore for 5 nights :

Room charge = 5×[1.07($99.95)] +

Total room charge = 5×[1.07($99.95)] + one time untaxed fee

Total room charge = 5×[1.07($99.95)] + $9

= $543.7325
