A regular hexagon has sides that are all congruent and angles that all measure 120 degrees. This means the angles of a regular hexagon add up to 720 degrees. ... An irregular hexagon has sides that are not the same measurement and can have points facing inward as well as outward.

What is the volume of this cone?

Andrej [43]

Answer:

Option A $41.9\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

In this problem we have

$r=4/2=2\ ft, h=10\ ft$

substitute the values

$V=\frac{1}{3}\pi (2)^{2}(10)$

$V=41.9\ ft^{3}$

A rectangular tank measures 16 cm by 9 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many lite

trapecia [35]

Answer:

1,440 cubic centimeter = 1,440 milliliters

1,440 cubic centimeter= 1.44 liters

Step-by-step explanation:

Volume of the rectangular tank = length × width × height

Length = 16 cm

Width = 9 cm

Height = 10 cm

Volume of the rectangular tank = length × width × height

= 16 cm × 9 cm × 10 cm

= 1,440 cm³

Volume of the rectangular tank = 1,440 cm³

How many milliliters of water are in the tank when it is full?

1 cubic centimeter = 1 milliliter

1,440 cubic centimeter = 1,440 milliliters

How many liters?

1 cubic centimeter = 0.001 liters

1,440 cubic centimeter= 1.44 liters

Find the missing angle measure A=51°, B=82°, C=5x+2

Shalnov [3]

I'm assuming you mean triangle angles?
If so, all angles add up to 180 so combine them and set them equal to 180.
51+82+5x+2=180
135+5x=180
5x=45
x=9

A pond has 150 fish and the population decreases by 8% each day. How many days before there are 30 fish

nlexa [21]

Answer:

19 days

Step-by-step explanation:

Given

$a = 150$ --- initial

$r = 8\%$ -- rate

Required

Days when the fish gets to 30

The function is exponential and as such it follows;

$y = ab^x$

Where x represents the number of days and y the number of fishes

Because the fishes decreases;

$b = 1 - r$

So, we have:

$b = 1 - 8\%$

Express as decimal

$b = 1 - 0.08$

$b = 0.92$

In $y = ab^x$

$a =150$

$y = 30$

$b = 0.92$

So, we have:

$30 = 150 * 0.92^x$

Divide both sides by 150

$0.2 = 0.92^x$

Take log of both sides

$log(0.2) = log(0.92^x)$

Apply law of logarithm

$log(0.2) = x\ log(0.92)$

Make x the subject

$x = \frac{log(0.2)}{log(0.92)}$

$x = \frac{-0.6990}{-0.0362}$

$x = 19.309$

$x \approx 19$

<em>Hence, it takes approximately 19 days</em>
