Answer:

b. 55°

Step-by-step explanation:

Complementary angles have a sum of 90°.

∠ABC +∠CBD = 90° . . . . . . the given relation

∠ABC + 35° = 90° . . . . . . . . . substitute the given value

∠ABC = 55° . . . . . . . . . . . . . . subtract 35° from both sides

∠ABC = ∠EBF = 55° . . . . . . vertical angles are congruent

Answer:

answer is 27 degrees

Step-by-step explanation:

first of all complementary angles add up to 90 degrees and you were given one angle

A manager found that 4 out of 36 parts manufactured in one day were defective.
Approximately, what percentage of the parts was NOT defective?

Answers

Answer: Percentage of not defective parts =88.88% which can be rounded up to 89%

Step-by-step explanation:

Total part manufactured= 36

defective parts = 4

Non defective parts = 36-4 = 32.

Percentage of not defective parts = Number of not defective parts / Total parts manufactured x 100

= 32/36 x 100= 88.88%

Solve the equation below for X
1/3(-x + 3) = -x - 4

Answers

Solve the equation below for X

1/3(-x + 3) = -x - 4

Answer: x = -15/2 = -7.500

Work~~

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

1/3*(-x+3)-(-x-4)=0

Step by step solution :

STEP

Simplify —

Equation at the end of step

(— • (3 - x)) - (-x - 4) = 0

STEP

Equation at the end of step 2

(3 - x)

——————— - (-x - 4) = 0

STEP

Rewriting the whole as an Equivalent Fraction

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 3 as the denominator :

-x - 4 (-x - 4) • 3

-x - 4 = —————— = ————————————

1 3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

STEP

Pulling out like terms

4.1 Pull out like factors :

-x - 4 = -1 • (x + 4)

Adding fractions that have a common denominator :

4.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(3-x) - ((-x-4) • 3) 2x + 15

———————————————————— = ———————

3 3

Equation at the end of step

2x + 15

——————— = 0

STEP

When a fraction equals zero :

5.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

2x+15

————— • 3 = 0 • 3

Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

2x+15 = 0

Solving a Single Variable Equation:

5.2 Solve : 2x+15 = 0

Subtract 15 from both sides of the equation :

2x = -15

Divide both sides of the equation by 2:

x = -15/2 = -7.500

One solution was found :

x = -15/2 = -7.500

This is the opening extract of the novel, The Woman In Black. In this extract, the narrator discusses what his life is like now, long after a traumatic ordeal with a ghostly woman who stole the life of his only son.CHRISTMAS EVEIt was nine-thirty on Christmas Eve. As I crossed the long entrance hall of Monks Piece on my way home from the dining room, where we had just enjoyed the first of the happy, festive meals, towards the drawing room and the fire around which my family were now assembled, I paused and then, as I often do in the course of an evening, went to the front door, opened it and stepped outside.I have always liked to take a breath of the evening, to smell the air, whether it is sweetly scented and balmy with the flowers of midsummer, pungent with the bonfires and leaf-mould of autumn, or crackling cold from frost and snow. I like to look about me at the sky above my head, whether there are moon or stars or utter blackness, and into the darkness ahead of me; I like to listen for the cries of nocturnal creatures and the moaning rise and fall of the wind, or the pattering of rain in the orchard trees, I enjoy the rush of air towards me up the hill from the flat pastures of the river valley.Tonight, I smelled at once, and with a lightning heart, that there had been a change in the weather. All the previous week, we had had rain, chilling rain and a mist that lay low about the house and over the countryside. From the windows, the view stretched not farther than a yard or two down the garden. It was wretched weather, never seeming to come fully light, and raw, too. There had been no pleasure in walking, the visibility was too poor for any shouting and the dogs were permanently morose and muddy. Inside the house, the lamps were lit throughout the day and the walls of larder outhouse and cellar oozed damp and smelled sour, the fires sputtered and smoked, burning dismally low.My spirits have for many years now been excessively affected by the ways of the weather, and I confess that, had it not been for the air of cheerfulness and bustle that prevailed in the rest of the house, I should have been quite cast down in gloom and lethargy, unable to enjoy the flavour of life as I should like and irritated by my own susceptibility. But Esme is merely stung by inclement weather into a spirited defiance, and so the preparations four our Christmas holiday had this year been more than usually extensive and vigorous.I took a step or two out from under the shadow of the house so that I could see around me in the moonlight. Monks piece stands at the summit of land that rises gently up for some four hundred feet from where the little River Nee traces its winding way in a north to south direction across this fertile, and sheltered, part of the century. Below us are pastures, interspersed with small clumps of mixed, broadleaf woodland. But at our backs for several square miles it is quite a different area of rough scrub and a heathland, a patch of wildness in the midst of a well-farmed country. We are but two miles from a good-sized village, seven from the principal market town, yet there is an air of remoteness and isolation which makes us feel ourselves to be much further from civilization.
