What is the best estimate of the sum of the fractions?

StartFraction 31 over 4 EndFraction + StartFraction 17 over 3 EndFraction + StartFraction 8 over 18 EndFraction

Answers

Answer 1

Answer:

Let's add the fractions first and then we can estimate the sum.

= 31/4 + 17/3 + 8/18

change to common denominators

= 279/36 + 204/36 + 16/36

add numerators only

= 499/36 or 13 31/36 or 13.86

ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.

Answers

Answer: Actually the answer up there is wrong here is your answer:

The x -coordinate of the reflection is -4. and The reflection is in Quadrant II.

Step-by-step explanation: there you go have a great day.=D

The correct description for when (4, 6) is reflected across the y-axis,

⇒ The x-coordinate of the reflection is -4.

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

Point (4, 6) is reflected across the y-axis.

We know that;

The rule of reflection about the y - axis is,

⇒ (x, y) → (- x, y)

So, Point (4, 6) is reflected across the y-axis, the point is,

⇒ (4, 6) → (- 4, 6)

Thus, The correct statement is,

⇒ The x-coordinate of the reflection is -4.

The maximum speed that an 888-foot boat can reach is___kilometers per hour.
A 16-foot sailboat at top speed is_____as fast as a 4-foot sailboat at top speed.

Answers

Answer:

The longer the sailboat is, the faster it can go.

For a boat to reach the speed of 10 kilometers per hour, it needs to be at least 16 feet long.

The maximum speed that an 8-foot boat can reach is 7 kilometers per hour.

A 16-foot sailboat at top speed is 2 times as fast as a 4-foot sailboat at top speed.

Step-by-step explanation:

I did it on Khan Academy and I got it right!

The correct fill in the blanks are as follows;

The longer the sailboat is, the faster it can go.

For a boat to reach the speed of 10 kilometers per hour, it needs to be at least 16 feet long.

The maximum speed that an 8-foot boat can reach is 7.1 kilometers per hour.

A 16-foot sailboat at top speed is 2 times as fast as a 4-foot sailboat at top speed.

Given;

The maximum speed that a sailboat can reach depends on the size of the boat.

The graph below shows the maximum speed, v, that a sailboat can reach as a function of its length, L.

The steps are used to solve the problem given below;

1. In the question given the maximum speed that a sailboat can reach depends on the size of the boat.

Therefore, The longer the sailboat is, the faster it can go.

The longer the sailboat is, the faster it can go.

2. In the graph a boat reaches the speed of 10 kilometers per hour, the slope of the graph at 16 feet.

For a boat to reach the speed of 10 kilometers per hour, it needs to be at least 16 feet long.

3. The maximum speed at which the 8-foot boat can reach the slope of the graph is 7.1 kilometers per hour.

The maximum speed that an 8-foot boat can reach is 7.1 kilometers per hour.

4. The top speed of a 16-foot boat is 10 kilometers per hour and of a 4-foot boat is 5 kilometers per hour.

       Then, The ratio is,

       [tex]= \dfrac{10}{5}\\\\= 2[/tex]

Answers

Answer:  The sun shines directly on the equator region.

Step-by-step explanation: Ultimately, the temperature in an area depends on the amount of the Sun's energy reaching the surface in that area. The amount of solar energy in a given area is greater at the equator than in an equal area at the poles, which is why the equator temperature is warmer than the polar temperatures. Therefore it is B

There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.How does the author develop the idea that humanity's early fire-starting tools may have been dangerous?
