Answer:

-77k²m³

Step-by-step explanation:

The variable arrangement is the same for each term, so we simply combine their coefficients:

k²m³ +22k²m³ -100k²m³ = (1 +22 -100)k²m³ = -77k²m³

Put these numbers in order from least to greatest 12%, -1/2, 0, -0.22, 0.56

uysha [10]

Answer: -1/2, -0.22, 0, 12%, 0.56

Step-by-step explanation:

-1/2 is equal to -0.50, making it the number with the least value.

-0.22 is closer to 0 than -0.50, meaning it is greater then -0.50 and less than 0.

0 is between the negative and positive numbers, giving it the spot that it has.

12% is equivalent to 0.12, meaning it is more than 0, and less than 0.56, which is the greatest number.

0.56 has more value than any other number in the problem, meaning it goes last in the order.

Y 45° 30° N 17 I need help pls

melisa1 [442]

Answer:

x=29.4

Step-by-step explanation:

To help find the sides of a triangle, I use SOHCAHTOA.

SOH - CAH - TOA

S=O/H ( $Sine=\frac{opposite}{hypotenuse}$ )

C=A/H ( $Cosine=\frac{adjacent}{hypotenuse}$ )

T=O/A ( $Tangent =\frac{opposite}{adjacent}$ )

Let's find x first. We know 2 parts of the triangle: the adjacent leg, and the angle that is opposite of that.

So it would be tangent (tan).

opposite = 17

adjacent = 30°

Plug these numbers into the calculator and you should get your answer.

$\frac{17}{tan(30)} = 29.44486372...$

x=29.4

Try to do y on your own and let me know if you have any questions!

Also correct me if I'm wrong on anything.

Hope this information helps!

An international company has 27,100 employees in one country. If this represents 22.6% of the company's employees, how many empl

Step2247 [10]

Answer:

The total employee of the company is 11912

Step-by-step explanation:

The employee in one country = 27,100

Let the total population be P

$\frac{ 22.6}{100} *P = 27,100$

P = $\frac{27100*100}{22.6}$

P = 11911.5

P = 11912 (approximately)

So the total employee of the company is 11912
