Answers

Answer:

the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

Step-by-step explanation:

Using, the formula y1+y2/x1-x2,

Choosing any two points, make the expression:

1-2/125-155

simplify:

-1/-30

the slope of the equation is -1/-30.

to find y intercept, using the function y=mx+b, plug in the slope and one of the two points that you used:

y would be 2

x would be 155

b is the y intercept

2= -1/-30•155 + b

2=5⅙+b

b = - 3⅙

the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

How are the rules for dividing two negative fractions related to the rules for multiplying
two negative fractions? Will the answer be positive or negative? Explain.

Answers

The answer will be negative, the rules are a negative plus a negative equals a positive and a positive plus a positive equals a negative

The relation between multiplying and dividing two negative fractions is needed.

When multiplying and dividing two negative fractions the answer will be always positive.

Let [tex]-\dfrac{a}{b}[/tex] be one fraction

and [tex]-\dfrac{c}{d}[/tex] be another fraction

Let us multiply them

[tex]-\dfrac{a}{b}\times -\dfrac{c}{d}=+\dfrac{ac}{bd}[/tex]

Let us divide them

[tex]\dfrac{-\dfrac{a}{b}}{-\dfrac{c}{d}}[/tex]

This can also be written as

[tex]-\dfrac{a}{b}\times -\dfrac{d}{c}=+\dfrac{ad}{bc}[/tex]

Since, multiplication and division are the inverse of each other the negative signs cancel each other and the sign is positive.

Hence, when multiplying and dividing two negative fractions the answer will be always positive.

Henry makes $12.50 per hour for the first 40 hours he works in a week. For 5 points
each additional hour he makes $18 per hour. How much did he make if he
worked 44 1/2 hours last week? *

Answers

Answer:

He made $581 if he worked 44 1/2 hours last week

Step-by-step explanation:

Let us solve the question

∵ Henry makes $12.50 per hour for the first 40 hours

∵ For each additional hour, he makes $18 per hour

→ We need to find how much he made if he worked 44 1/2 hours

→ At first, find his earning for the first 40 hours

∵ His earning in the first 40 hours = 40 × 12.50

∴  His earning in the first 40 hours = $500

→ Find how many hours he worked after the first 40 hours

∵ 44 1/2 - 40 = 4 1/2 hours

∴ He worked 4 1/2 hours over the first 40 hours

→ Find his earning from them

∵ His earning in 4 1/2 hours = 4 1/2 × 18

∴ His earning in 4 1/2 hours = $81

→ Now add the two amounts to find his total earning

∵ His total earning = 500 + 81

∴ His total earning = $581

∴ He made $581 if he worked 44 1/2 hours last week

3x + 8 = 2x + 21

Answers

Answer:

Step-by-step explanation:Simplifying

3x + 8 = 2x + -21

Reorder the terms:

8 + 3x = 2x + -21

Reorder the terms:

8 + 3x = -21 + 2x

Solving

8 + 3x = -21 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

8 + 3x + -2x = -21 + 2x + -2x

Combine like terms: 3x + -2x = 1x

8 + 1x = -21 + 2x + -2x

Combine like terms: 2x + -2x = 0

8 + 1x = -21 + 0

8 + 1x = -21

Add '-8' to each side of the equation.

8 + -8 + 1x = -21 + -8

Combine like terms: 8 + -8 = 0

0 + 1x = -21 + -8

1x = -21 + -8

Combine like terms: -21 + -8 = -29

1x = -29

Divide each side by '1'.

x = -29

Simplifying

x = -29

3x + 8 = 2x + 21

3x - 2x + 8 = 21

x + 8 = 21

x = 21 - 8

x = 13

[tex]\angle AFY=140^\circ[/tex]

[tex]\angle LIM=117^\circ[/tex]

Step-by-step explanation:

The sum of interior angles of a polygon of n sides is:

[tex]S=180^\circ (n-2)[/tex]

The image shows a 6-side polygon. The sum of the interior angles is:

[tex]S=180^\circ (6-2)=720^\circ[/tex]

The sum of all the shown interior angles must equal 900°:

[tex]125+100+y+117+121+y+23=720[/tex]

Simplifying:

[tex]486+2y=720[/tex]

Solving:

[tex]2y=720-486[/tex]

[tex]2y=234[/tex]

[tex]y=234 / 2=117[/tex]

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.What was the main problem with relying on nature to start a flame? (5 points)Fire could only be collected with "sticks of wood" that were hard to find.Fire had to be "carefully guarded," requiring someone to stay behind from hunting.Fire had to be "carried to the home," which could be dangerous and awkward.Fire was likely hard to find, requiring a "long journey and a deal of trouble."
