Using distribution you do 9*8=72 then 9*(-x)=-9x
72-9x=3x
In both sides +9x
72=12x
Divide by 12
X=6

It takes 18 hours to fill a pool using 8 garden hoses. How long would it take to fill the same pool using 9 garden hoses?
levacccp [35]
Use rates, so 8 garden hoses over 18 hours
then find the how many hours one garden house can fill up by doing this = 18/8 you divide the 8 for both sides which is about 2.25/1
so then you times 9 which is about 20/9 hoses
your answer is 20

A car dealer acquires a used car for $14,000, with terms FOB shipping point. compute total inventory costs assigned to the used
Artyom0805 [142]

Given:

A car dealer acquires a used car for $14,000, with terms FOB shipping point.

Transportation cost = $100

Shipping insurance = $120

Car import duties = $970

To find:

The total inventory costs assigned to the used car.

Solution:

We know that,

Inventory costs = Value of used car + Transportation cost + Shipping insurance + Car import duties

Inventory costs = $14,000 + $100 + $120 + $970

Inventory costs = $15,190

Therefore, total inventory costs assigned to the used car is $15,190.

What is the rectangular form of z= 40(cos(7pi/6)+ i sin(7pi/6))
Anastaziya [24]

Answer:

C. z = -20\sqrt{3}-i\,20

Step-by-step explanation:

The rectangular form of a complex number is represented by the following formula:

z = a+i\,b (1)

Where each coefficient can be determined as function of the polar components:

a = r\cdot \cos \theta (2)

b = r\cdot \sin \theta (3)

Where:

r - Magnitude of the complex number, dimensionless.

\theta - Direction of the complex number, measured in radians.

If we know that r = 40 and \theta = \frac{7\pi}{6}, then the rectangular form of the number is:

a = 40\cdot \cos \frac{7\pi}{6}

a = -20\sqrt{3}

b = 40\cdot \sin \frac{7\pi}{6}

b = -20

The rectangular form of z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right) is z = -20\sqrt{3}-i\,20. The correct answer is C.
