6 0

Answer:

Step-by-step explanation:

Round 6.1 down to 6. If you divide 18 by 3 you get 6.

Therefore, 6 is one third of 18.

It takes 1 yard 2 feet of material to make a pillow. How much material is required to make 8 pillows?

Monica [59]

40 feet or 13 yards and 1 foot

using the conversion

1 yard = 3 feet then 1 yard 2 feet = 5 feet ← material for 1 pillow, hence

8 pillows require 8 × 5 = 40 feet

The mass of a cylinder made of barium with a height of 2 inches depends on the radius of the cylinder as defined by the function

svp [43]

Answer:

$r=22.07\ in$

Step-by-step explanation:

<em><u>The correct function is</u></em>

$m(r)=7.188\pi r^{2}$

we have

System of equations

$m=7.188\pi r^{2}$ -----> equation A

$m=11,000$ -----> equation B

Solve by substitution method

substitute equation B in equation A

$11,000=7.188\pi r^{2}$

Solve for r

Divide by 7.188π both sides

$r^{2}=\frac{11,000}{7.188\pi}$

square root both sides

$r=22.07\ in$

The line is parallel to

tino4ka555 [31]

Recall that parallel lines have the same slope.

A line parallel to y= (-3/5)x + 8 would have the same equation EXCEPT for a different constant, C, replacing that '8.'

This new line passes thru (-5,-3). In y= (-3/5)x + C, replace x with -5 and replace y with -3. Then:

-3 = (-3/5)(-5) + C. Find C:

-3 = 3 + C. Thus, C = 6

Thus, the equation of the new line is y= -(3/5)x - 6

Check: Let x = -5 and y = -3. Is the above equation true?

-3 = (-3/5)(-5) - 6

-3 = 3 - 6, or -3 = -3.

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.
