Answer:

I can only help with 5 and 6 which both are A.

Explanation:

that's because Cosine is adjacent to the angle (the angle being 30 degrees and the side next to it is 43mm) divided by the hypotenuse (longest side of a right triangle. The 50 mm). A way you can remember the sin, cosine and tangent is SOH CAH TOA. Sine=opposite over hypotenuse, Cosine = adjacent over hypotenuse, Tangent = opposite over adjacent. For the next one, it is the same principal. X is adjacent to 22 degrees and the other number is the hypotenuse so it has to be Cosine.

koban [17]

Answer: 32 paving stones

Step-by-step explanation:

Hi, to answer this question, first we have to convert the measures of the paving stones into meters.

Since: 1m = 100 cm

50 cm /100 = 0.5m

Now, we have to calculate the area of each paving stone:

Area of a square: s^2 = 0.5^2 = 0.25m2

Next, the area of the path.

Area of a rectangle = width x length = 1 x 8 = 8 m2

Finally, we have to divide the area of the path by the area of each paving stone:

8/0.25 = 32 paving stones

Feel free to ask for more if needed or if you did not understand something.

juin [17]

Answer:

z = 3

Step-by-step explanation:

we use the method

(q^4)^z = q^(4*z)

now

4*z = 12

z = 12 / 4

Say that australia has a working population of 11,565,470 people, and that the average salary is $26,450 annually. how much tax

Archy [21]

The tax revenue Australia would generate each year is $96,054,697,991.

<h3>What is the percentage?</h3>

The percentage is the value per hundred.

Working population of Australia = 11,565,470 people

Annual average salary = $26,450

Income tax rate = 31.4%

Tax revenue generated by each resident = 26450*(31.4/100)

Tax revenue generated by each resident =$8305.3

So, Tax revenue generated by 11,565,470 residents = 11,565,470*8305.3

Tax revenue generated by 11,565,470 residents = $96,054,697,991

Therefore, the tax revenue Australia would generate each year is $96,054,697,991.
