Answer:

10 students would spend $30.

Step-by-step explanation:

In order to find this, start by looking for the cost per student. We can do this by dividing the overall cost by the number of students.

$12/4 students = $3 per student.

Now we take that unit rate and multiply by the new number of students.

$3 * 10 students = $30 total spent.

f(x)=tan 90º=indeterminated   or   ∞

Answer: y-value=indeterminated or ∞.

2)
Law of sines:
a/sin A=b/ sinB
In this case:
24 /sin 92º=7/sin Z
sin Z=(7*sin 92º)/24=0.29148...≈0.29

Z=arc sin (0.29)=16.95º

Answer: Z=16.95º.

3)
Law of cousines:
a²=b²+c²-2bc(cos A)
In this case:
12²=22²+19²-2(22)(19)cos T
144=484+361-836 cos T
-836 cos T=144-484-361
-836 cos T=-701
cos T=-701/-836
cos T=0.83851...≈0.84
T=arc cos (0.84)=33.02

Answer: T=33.02º

4)

What is 3 log Subscript 2 Baseline x minus (log Subscript 2 Baseline 3 minus log Subscript 2 Baseline (x + 4)) written as a sing
Serhud [2]

Answer:

\log_{2} [\frac{x^{3}(x + 4)}{3}]

Step-by-step explanation:

We have to write the following logarithmic expression as a single logarithm.

The given expression is

3\log_{2} x - [\log_{2} 3 - \log_{2}(x + 4)]

= 3\log_{2} x - \log_{2} (\frac{3}{x + 4})

{Since, \log A - \log B = \log \frac{A}{B}, from the properties of logarithmic function }

= \log_{2} x^{3}  - \log_{2} (\frac{3}{x + 4})

{Since, a\log b = \log b^{a}, which also a logarithmic property}

= \log_{2} [\frac{x^{3}}{\frac{3}{x + 4}}]

= \log_{2} [\frac{x^{3}(x + 4)}{3}] (Answer)

6 - 3/4x + 1/3 = 1/2x + 5 <br><br> help
andre [41]

Answer:

x=15/16

Step-by-step explanation:

Let's solve your equation step-by-step.

6−34x+13=12x+5

6+−34x+13=12x+5

Multiply all terms by x and cancel:

6x+−34+1x3=12+5x

193x+−34=5x+12(Simplify both sides of the equation)

193x+−34−5x=5x+12−5x(Subtract 5x from both sides)

43x+−34=12

43x+−34+34=12+34(Add 3/4 to both sides)

43x=54

(34)*(43x)=(34)*(54)(Multiply both sides by 3/4)

x=1516

Check answers. (Plug them in to make sure they work.)

x=1516(Works in original equation)
