Answer:

The answer would be x=7.3 cm

Step-by-step explanation:

Since you are using the angle of 20 degrees and you have the measure of 10 cm for its adjacent side, solving for x would mean you would use tan.

20=x/10

10*20tan=x

200tan=x

7.279404......=x

But when you do 200 tan on the calculator, you have to make sure you press the equal sign after.

A line passes through the point (6,-2) and has a slope of -3/2

natita [175]

Answer:

-1.5x - y + 7 = 0

Step-by-step explanation:

The formula for point slope form is y-yA = m(x - xA).

y - (-2) = -1.5(x + 6)

y + 2 = -1.5x + 9

y = -1.5x + 9 - 2

y = -1.5x + 7

-1.5x - y + 7 = 0 is the point slope form.

Please help me with this math problem I don’t know it I need to pass this class !!!!!!

Alisiya [41]

The correct option is Option 4: $2a^2b^3 + 10ab^4$

Step-by-step explanation:

Given

Length of box = l = ab

Width of box = w = a+5b

Height of box = h = 2b^2

The volume of a box is given by:

$V = Length*Width*Height\\V = l*w*h$

Putting the values

$V = (ab)(a+5b)(2b^2)\\ = (ab)(2b^2)(a+5b)\\=(2ab^3)(a+5b)\\Distributive property\\=(2ab^3*a) + (2ab^3*5b)\\=2a^2b^3 + 10ab^4$

Hence,

The correct option is Option 4: $2a^2b^3 + 10ab^4$

A car dealership pays you 4% commission on your first $8,000 in car sales and 8% commission on additional sales over the $8,000.

Zigmanuir [339]

Answer:

Total Commission = $400

Step-by-step explanation:

Since total is $9000 (in sales) -- commision is 4% on the first $8000 and 8% in the additional part over $8000 (9000-8000=1000). So 8% on $1000.

<u>Total commission</u> = 4% of 8000 + 8% of 1000

= (0.04)(8000) + (0.08)(1000)

= 400

Total Commission is $400

How do I do this please help

Umnica [9.8K]

Answer:

wrong as his calculation was incorrect at initial level itself when he found the result of the division

Step-by-step explanation:

Andre said

3 ÷ $\frac{2}{3}$

$=3 \times \frac{3}{2}$

$=\frac{3 \times 3}{2}$

$=\frac{9}{2}$

but andre calculated it as

$=4\tfrac{1}{3}$

$=\frac{4 \times 3 + 1}{3}$

$=\frac{13}{3}$

Hence his calculation was incorrect at initial level itself
