Frank rented a truck for one day. There was a base fee of $16.99, and there was an additional charge of 76 cents for each mile driven Frank had to pay
$228.27 when he returned the truck. For how many miles did he drive the truck?
miles

Answers

Answer:

267

Step-by-step explanation:

Answer: He drove the truck for 278 miles.

Step-by-step explanation:

We can represent the situation by the equation,  16.99 + 0.76x = 228.27  where x is the number of miles.  16.99 is the base fee an 0.76 is the same as 76 cents .  

Solve for x in the equation to find out how many miles was driven.

16.99 + 0.76x = 228.27

-16.99                -16.99

0.76x = 211.28

x= 278

Presuming the distribution is normal, what is the yield strength exceeded by 99 percent of the population

Answers

Answer:

Step-by-step explanation:

Given the following :

Midpoint (S)____F

S y 93 95 97 99 101 103 105 107 109 111 f 19 25 38 17 12 10 5 4 4 2

Calculating the mean and standard deviation using a calculator :

The mean(m) of the data above = 98.12

Standard deviation (sd) = 4.02

Proportion = 99% of population

From z table = 2.33

Using :

Zscore =(x - m) / sd

2.33 = (x - 98.12) / 4.02

2.33 * 4.02 = x - 98.12

9.3666 = x - 98.12

9.3666 + 98.12= x

x = 107.4866

X = 107.50

Two goals post are 8m apart. A footballer is 34m from one and 38m from the other. Within what angle must he kick the ball if he is to score a goal?​

Answers

Answer:

  11.06°

Step-by-step explanation:

The law of cosines can be used to find the angle. The sides adjacent to that angle are a=34, b=38, and the side opposite is c=8. Then the angle is found from ...

  c² = a² +b² -2ab·cos(C)

  cos(C) = (a² +b² -c²)/(2ab)

  C = arccos((a² +b² -c²)/(2ab))

  C = arccos((34² +38² -8²)/(2·34·38)) = arccos(317/323)

  C ≈ 11.06°

From the footballer's viewpoint, the goal posts are 11.06° apart.

200 bottles of equal capacity hold 350 liters of water .How much does each hold?​

Answers

Answer:

SECRET HAHAHAHHA

Step-by-step explanation:

Answer:

1.75 liters

Step-by-step explanation:

We know that all 200 bottles can hold 350 liters of water.

Suppose each bottle holds b liters of water. Then we can model the situation in terms of b:

200b = 350

Divide both sides by 200:

b = 350/200 = 35/20 = 1.75

The answer is thus 1.75 liters.

Write the three forms of the line parallel to the line represented by the equation, 8x+3y=11 such that it passes through the point (9, -5).

Answers

Answer:

8x + 3y = 57y = -8/3x + 19y + 5 = -8/3(x - 9)

Step-by-step explanation:

Given function

8x+3y=11

Line parallel to the given has the same slope and passes through the point

(9, -5)

Determining the equation

8x + 3y = c8*9 + 3*(-5) = cc=72 - 15c = 57

So the function is in standard form

8x + 3y = 57

Converting to slope-intercept form

y = mx + b3y = -8x + 57y = -8/3x + 573y = -8/3x + 19

Point-slope form, using the given point

y - y1 = m(x - x1)y - (-5) = -8/3(x - 9)y + 5 = -8/3(x - 9)

A motorcyclist is riding along a mountain trail that runs parallel to a road below. In fact the trail is 6 meters above the road. The motorcyclist then notices a flat bed truck directly below moving at the same speed and decides to drive off the trail, without changing speed. Fortunately, the motorcycle safely lands on the flatbed of the truck. What would the outcome have been if the trail was 12 meters above the road, but all other parameters remain the same?

Answers

Answer:

The motorcycle would still land on the truck FLATBED just the way it landed when the trail was 6 meters above the road.

Step-by-step explanation:

Based on the information given about the motorcyclist we were told that the trail was 6 meters above the road in which despite that the motorcyclist drive off the trail without changing his motorcycle speed which made the motorcycle to land on the truck FLATBED which means that if the trail was 12 meters above the road while all other parameters remain the same what the outcome could have been is that the motorcycle would still land on the truck FLATBED just the way it safely landed when the trail was 6 meters above the road.

Therefore FLATBED truck can simply be defined as truck which does not have any thing covering both the right side and left side of truck and as well does not have roof making the truck to have a FLATBED or flatbody which is why most of this type of truck are mostly used to transport goods or loads that are heavy.

E. Forman1911THE MATCHThere 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.Which line from the bolded paragraph shows the value of the match?
