Answer:

v=2144.66

Step-by-step explanation:

formula: 4/2 (pi) (r)³

................

Answer:

V = 2143.573333333333.... in³

Step-by-step explanation:

Formula for volume -> V = 4/3 πr³

We know the circumverence now we need to et the radius.

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

Divide the diameter by 2.

There you go, you found the circle's radius.

16pi/pi = 16/2 = 8

V=4/3πr³

V=4/3π8³ = 2143.5733333333333333333333333333333333333333333333333333333333333...

Answer:

  a) -3p +4q

  b) -6x +3y

Step-by-step explanation:

Use the distributive property to eliminate parentheses. Use the properties of arithmetic to combine the numbers.

__

The order of operations tells you to start with the inner parentheses and work outward.

  [tex]-\dfrac{1}{3}(6(p+q)-3(p-2(p-3q)))=-\dfrac{1}{3}(6(p+q)-3(p+(-2)(p) +(-2)(-3q)))\\\\=-\dfrac{1}{3}(6(p+q)-3(p-2p+6q))=-\dfrac{1}{3}(6(p+q)-3(-p+6q))\\\\=-\dfrac{1}{3}((6)(p)+(6)(q)+(-3)(-p)+(-3)(6q))=-\dfrac{1}{3}(6p+6q+3p-18q)\\\\=-\dfrac{1}{3}(9p -12q)=(-\dfrac{9p}{3})+(-\dfrac{-12q}{3})=\boxed{-3p+4q}[/tex]

__

Same deal for the second expression: use the distributive property and combine like terms.

  [tex]y-\dfrac{2}{3}(9x-3y)=y+(-\dfrac{2\cdot9x}{3})+(-\dfrac{2(-3y)}{3})\\\\=y-6x+2y=\boxed{-6x+3y}[/tex]

Answer:

2cis(20°)

Step-by-step explanation:

we are given that

[tex] \displaystyle \rm z = 10cis ({30}^{ \circ} )[/tex]

[tex] \displaystyle \rm w = 5cis ({10}^{ \circ} )[/tex]

We want to find z/w . To do so, divide 10cis(30°) by w = 5cis(10°) which yields:

[tex] \displaystyle \rm \frac{ z}{w} = \frac{10cis ({30}^{ \circ} )}{5cis( {10}^{ \circ} )}[/tex]

recall that,

[tex] \displaystyle \rm \frac{ r_{1} cis ({ { \theta}_{1}} )}{ r_{2}cis( { \theta}_{2})} = \frac{ r_{1} }{ r_{2} } cis({ \theta}_{1} - { \theta}_{2})[/tex]

consider,

Therefore, utilizing the formula yields:

[tex] \displaystyle \rm \frac{ z}{w} = \frac{10cis ({30}^{ \circ} )}{5cis( {10}^{ \circ} )} \\ \implies \rm\frac{ z}{w} = \dfrac{10}{5} cis( {30}^{ \circ} - {10}^{ \circ} ) \\ \implies \rm \dfrac{z}{w} = \boxed{ \rm2cis( {20}^{ \circ} )}[/tex]

and we're done!

NB: cis(x) is also known as cos(x)+i×sin(x)

Answer:

Think about the following situations: speed limits on the highway, minimum payments on credit card bills, number of text messages you can send each month from your cell phone, and the amount of time it will take to get from home to school.

Answer:

2: 125

4: 55

7: 125

3: 125

Step-by-step explanation:

Since the top and bottom lines are parallel, 2 is equal to 6.

since angles 4+2 sums up to a straight line, its 180 degrees

125+55 is 180

same with 3, 3+4 is 180

7 is same as 3

Answer:

1,044cm

Step-by-step explanation:

46-21=25cm (the length of the top line)

30-14=16cm (the length of the other line on the left of the 21)

Split it into three rectangles, 25×16, 21×14 and 25×14

25×16 = 400cm

21×14 = 294cm

25×14 = 350cm

Add to together: 400+350+294= 1044cm

the other commenter is right

Answer:

176/317

Step-by-step explanation:

The formula for slope is [tex]\frac{y2 - y1}{x2 - x1}[/tex], which means you have to subtract the second point's y coordinate (286) minus the first point's y coordinate (110).

Now you have [tex]\frac{286-110}{x2 - x1}[/tex] or [tex]\frac{176}{x2 - x1}[/tex].

Now you have to do the same for x.

446 - 129 = 317, which gives you the final answer of

[tex]\frac{176}{317}[/tex], or about 0.555.

Answer: Right triangle

Step-by-step explanation:

QR is perpendicular to line n, so the indicated angle is a right angle. Thus, QRS is a right triangle because a triangle with a right angle is a right triangle.

Answer:

b=3

Step-by-step explanation:

i subtracted 11 with the 26 and got 15 and then I divided the 5b with the 15 and got 3

Hope i helps<33

Answer:

b=3

Step-by-step explanation:

move the constant to the right-hand side and change its sign 5b = 26 - 11

subtract the numbers 5b = 15

divide both sides of the equation by 5 b = 3

Answer:

19+4i

Step-by-step explanation:

Multiply using the FOIL method, then combine the real and imaginary parts of the expression.

FOIL

A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial, Outer means multiply the outermost terms in the product, Inner means multiply the innermost terms, and Last means multiply the terms which occur last in each binomial.

Result of multiplication of complex numbers will be 19 + 4i

Given,

(3 + 2i)(5 – 2i)

Here,

Complex numbers standard form : x ± iy

Here,

x = real part

y = complex part.

i = iota = [tex]\sqrt{-1}[/tex]

So,

Multiplication :  (3 + 2i)(5 – 2i)

⇒15 -6i + 10i -4i²

Here,

i = √-1

i² = -1

So,

15 -6i + 10i -4i²

15 -6i + 10i - 4(-1)

⇒19 + 4i

Answer:

B = 21.4°

Step-by-step explanation:

Using the Law of Sines.

[tex]sin(42)/22=sin(B)/12[/tex]

Cross Multiply

[tex]12*sin(42)=22sin(B)[/tex]

Get Sin(B) by itself.

sin(B)= 12*sin(42°) / 22

B° = sin^-1((12*sin(42°))/22)

B = 21.4°

Answer:

-1

Step-by-step explanation:

The slope is the change in the Y value divided by the change in the X value. Therefore, the slope of this line is:

(-17-[-18])/(-7-[-6) = (-17+18)/(-7+6) = (1)/(-1) = -1

Answer:

-2/3

Step-by-step explanation:

To find the slope, you can pick two points on the graph and plug them into the slope formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]\frac{0-2}{6-3}[/tex]

[tex]\frac{-2}{3}[/tex]  is the same as [tex]-\frac{2}{3}[/tex]
