Answer:

-11

Step-by-step explanation:

$|-4b-8|+|-1-b^2|+2b^3$

Given the value of b=-2

Plug in the value of -2 for b and evaluate

$|-4b-8|+|-1-b^2|+2b^3$

$|-4(-2)-8|+|-1-(-2)^2|+2(-2)^3$

$|8-8|+|-1-4|+2(-8)$

$|0|+|-5|-16$

$0+5-16=-11$

Final answer is -11

Consider the expression 35.86 divided by 2.2 .

Anastasy [175]

Answer:

a = 100, b = 100
16.3

Step-by-step explanation:

a = 100 will convert the number on the numerator to whole number
b = 10 will convert the number on the denominator to whole number

But we need a = b in order not to change the value of the fraction, therefore we choose

a = b = 100

Multiplying both numerator and denominator by 100 will make the fraction:

35.86*100/2.2*100 =
3586/220 =
16 66/220 =
16 3/10
16.3

A coconut is a fruit that is made up of a hard outer shell that is spherical. Inside, there is a thick layer of coconut meat tha

Dvinal [7]

Answer:

V = 18816.57 in^3

Step-by-step explanation:

So we need to find the volume of the inner sphere. Try to picture the coconut as a circle with another circle inside of it. We know that the bigger circle is 55 inches wide, and the distance between the circumferences of the circles is 11 inches. that means the inner circle is 55 - 2(11) inches wide. This is because we have 11 inches of coconut meat on either side of the inner circle.

55 - 2(11) = 33 inches

The radius is half of the diameter, so r = 16.5 inches.

Now just use the formaula V = $\frac{4}{3}\pi r^{3}$

V = (4/3) * 3.14 * (16.5)^3

V = 18816.57 in^3

<em>Also, just a side note.. this is one big coconut..</em>
