For the given triangle, the tan of angle A equals C. \frac{5}{12}.

Step-by-step explanation:

Step 1; In the given triangle, the opposite side has a length of 15 units, the adjacent side has a length of 36 units while the hypotenuse of the triangle measures 39 units. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

cos A = \frac{oppositeside}{adjacentside}.

Step 2; The opposite side's length = 15 units,

The adjacent side's length = 36 units.

cos A = \frac{15}{36}, dividing the numerator and the denominator by 3, we get

cos A = \frac{5}{12}, which is option C.

Answer:

for #1 its the 1st and 4th box

for # 2 it's 13.5 and 20.25

Step-by-step explanation:

1st box - 10 ÷ 5 = 2 and 25 ÷ 5 = 5

4th box - 10 x 2 = 20 and 25 x 2 = 50

you have to make sure that you do the same thing for both sides of the equation

6 x 2.25 = 13.5

9 x 2.25 = 20.25

Solve: –3x – 24 ≤ –36 what is x equal to?
Kay [80]

Answer:

X <= 4

Step-by-step explanation:

-3x - 24<= -36

Make -3x the subject, by carrying -24 to the other side

Note: Moving -24 to the other side changes to + 24

-3x <= -36 + 24

-3x <= - 12

Minus cancels minus

3x <= 12

Divide both sides by 3,to get the value of x

3x/3 <= 12/3

x <= 12/3

x <= 4

Therefore, x equals to 4

<em><u>Problem One</u></em>

Remark

You don't pay a sales tax until cash is exchanged for goods or services.

So what is 70% off

Solution

Sale price = given price * (100% - 70%)

Sale Price = 72 * 30%

Sale Price = 72 * 30/100

Sale Price = 72 * 0.3

Sale Price = 21.6 dollars.

The sales tax is 5% of this amount

21.6 * 5/100 = 1.08

The total cost is = 21.6 + 1.08 = 22.68

Problem Two

If they marked up 100%, effectively they doubled the price.

New Price = old price + 100% of old price.

New Price = 48.50 + 48.50 = 97 dollars.

The sales tax is 6% * 97 = 6/100 * 97 = 5.82

Total Cost = Cost of item + Tax

Total Cost =97 + 5.82

Total Cost = 102.82 Answer <<<<
