Find the area of the figure at the right. Justify your
procedure.(brainliest included for correct answer)

Answers

Answer:

9 inches

Step-by-step explanation:

the top 6.1 inches - the bottom 3.1 inches where it cuts off so its 3x3

First, find the lengths of the missing sides. 6.1 - 3.1 = 3, and 6.9 - 3 = 3.9. Now split the figure (I will be splitting vertically, or where the line is). Now solve for the square. length * width = Area, so 3 * 3 = 9. Now solve for the rectangle. Again, length * width =Area so, 3.1 * 6.9 = 21.39. Now add both of the areas together. 21.39 + 9 = 30.39. Therefore, the area of the figure is
30.39 in. sq

2(2x - 8) > 4(3x - 12) Solve the inequality (Just like my previous problem) Make sure to show work!!

Answers

2(2x-8)
2•2x=4x
2•-8= -16
So now 4x-16
Now divide both sides by 4
4x/4=x
-16/4=-4
X=-4

Answer:

x < 8

Step-by-step explanation:

This is a special case, so at the end of the equation we'll flip the sign.

Distribute:

2 * 2x = 4x

2 * -8 = -16

4x - 16

4 * 3x = 12x

4 * -12 = -48

12x - 48

4x - 16 > 12x - 48.

Subtract 12 from both sides.

12 - 12 = 0

4x - 12x = -8x

-8x - 16 > -48

The additive inverse of subtraction is addition so do -16 + -48, which equals -64

-8x/-8 = x

-64/-8 = 8

Now this is where we flip our sign so here we go :)

x < 8

There.

A. passing bills and resolutions B. appointing judges C. appropriating state funds D. overseeing state agencies Please help me!!!adapted from Submarinesfrom The Story of Great Inventionsby Elmer Ellsworth Burns Successful navigation beneath the surface of the water, though not carried to the extent imagined by Jules Verne, was a reality at the beginning of the twentieth century. Instead of twenty thousand leagues under the sea, less than a hundred leagues had been accomplished, but no one can foretell what the future may have in store. The submarine is primarily utilized in wars. The weapon used by the submarine is the torpedo. The torpedo is itself a small submarine able to propel itself, and if started in the water toward a certain object, to go under water straight to the mark. It carries a heavy charge, either of guncotton or dynamite, which explodes when the torpedo strikes a solid object, such as a battle-ship. It would be very difficult for one submarine to fight another submarine, for the submarine when completely submerged is blind. It could not see in the water to find its enemy. The torpedo-boat-destroyer is able to destroy a submarine by torpedoes, shells full of high explosives, or quick-firing guns. Advantage must be taken of the moment when the submarine comes to the surface to get a view of her enemy. One of the great enemies of the submarine will probably be the air-ship, for while the submarine when under water cannot be seen from a ship on the surface, it can, under favorable conditions, be seen from a certain height in the air. The rising and sinking of the submarine depend on the principle of Archimedes. The upward push of the water is just equal to the weight of the water displaced. If the water displaced weighs more than the boat, then the upward push of the water is greater than the weight of the boat and the boat rises. However, the boat can be made to dive when its weight is just a little less than the weight of the water displaced. This is done by means of horizontal rudders which may be inclined so as to cause the boat to glide downward as its propeller drives it forward. There is one submarine built for peaceful pursuits. It is the Argonaut, invented by Simon Lake. This remarkable boat crawls along the bottom of the sea, but not at an immense depth. It is equipped with divers' appliances, and is used in saving wreckage. Divers can go out through the bottom of the boat, walk about on the sea bottom, and when through with their work re-enter the boat; all the while boat and men are, perhaps, a hundred feet below the surface. The divers' compartment, from which the divers go out into the water, is separated by an air-tight partition from the rest of the boat. Compressed air is forced into this compartment until the pressure of the air equals the pressure of the water outside. Then the door in the bottom is opened, and the air keeps the water out. The men in their diving-suits can then go out and in as they please. For every boat, there is a depth beyond which it must not go. The penalty for going beyond this depth is a battered vessel, for the pressure increases with the depth. Every time the depth is increased thirty-two feet, the pressure is increased fifteen pounds on every square inch. Beyond a certain depth, the vessel cannot resist the pressure. Submarines have been made strong enough to withstand the pressure at a depth of five thousand feet, or nearly a mile. Most submarines, however, cannot go deeper than a hundred and fifty feet. Air is supplied to the occupants of the boat either from reservoirs containing compressed air or oxygen, or by means of chemicals which absorb the carbon dioxide produced in breathing and restore the needed quantity of oxygen to the air.Select all the correct answers.Read the sentence from the passage.The submarine is primarily utilized in wars.Which two words have a similar denotation to the word utilized as it is used in the passage?A tiltedB.
