A camera company routinely ships cameras that have 4 defective cameras for every 800 cameras shipped. Bradley works at a photo shop that sells the cameras to consumers. If Bradley sells 200 cameras, how many can Bradley expect to be defective?

A.50 cameras

B.8 cameras

C.4 cameras

D.1 camera

Answers

D. 1 cuz think of it like this 8 divided by 4 = 2 and if that 2 is 200 hundred in every 200 hundred camera there’s 1 defective camera tell me if I’m wrong

The number of cameras Bradley expects to be defective if he sells 200 cameras is 1, so option D is correct.

What is ratio?

Comparing one quantity to another is what it is. For instance, the weight ratio is 1:3 if you weigh 30 kg and your father weighs 90 kg.

Given:

4 defective cameras for every 800 cameras shipped,

Bradley sells 200 cameras,

The ratio of the defective piece to cameras shipped = cameras shipped / defective cameras,

Ratio = 800 / 4 = 200

So for 200 cameras to be shipped, there is one defective piece.

Therefore, the number of cameras Bradley expects to be defective if he sells 200 cameras is 1.

Step-by-step explanation:

Because there are three semi-circles and three squares that are missing semi-circle chunks, you can just consider the shape three squares. Area of this square would be 16, so three would be 48. The perimeter is the outside so it would be 4 as well. In total, the full shape would be 40.

How many 1/4 inch cubes does it take to fill a box with width 2 3/4 inches, length 3 1/2 inches, and height 1 1/4 inches

Answers

Answer:

125 cubes brooooo gl

Step-by-step explanation:

In each side first layer for the width, 11 cubes can fit. Sine 1/4 can fit in one 4 times, 4 * 3 = 12. 12 plus 2 (2/4=1/2) is 14. So,

11 + 14 = 25.

25 is one layer. Since the height is 1 1/4 inches, multiply 25 by 5.

125 cubes bro.

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3

Answers

Ccccccccccccccccccccc

The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.

What is the equation?

More than one variable may be present inside a linear equation.

An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given equation,

13 = -3 + z

Since, A + B = B + A

Thus, -3 + z can be written as z - 3

So, 13 = z - 3

Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".

Which of these graphs is the solution set for the equation y = -3x - 2?

Answers

A because y=-3x-2 has these transformations
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation

Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2

P.S. wouldn't mind getting brainliest

I loved being a little girl, or rather I loved being a fairy princess, for that was who I thought I was.As I passed through a stormy adolescence to a stormy maturity, femininity increasingly became an exasperation, a brilliant subtle esthetic that was bafflingly inconsistent at the same time that it was minutely, demandingly concrete, a rigid code of appearance and behavior defined by dos and dont-dos that went against my rebellious grain. Femininity was a challenge thrown down to the female sex, a challenge no proud, self-respecting young woman could afford to ignore, particularly one with enormous ambition that she nursed in secret, alternately feeding or starving its inchoate life in tremendous confusion.Dont lose your femininity and Isnt it remarkable how she manages to retain her femininity? had terrifying implications. They spoke of a bottom-line failure so irreversible that nothing else mattered. The pinball machine was registered tilt, the game had been called. Disqualification was marked on the forehead of a woman whose femininity was lost. No records would be entered in her name, for she had destroyed her birthright in her wretched, ungainly effort to imitate a man. She walked in limbo, this hapless creature, and it occurred to me that one day I might see her when I looked in the mirror. If the danger was so palpable that warning notices were freely posted, wasnt it possible that the small bundle of resentments I carried around in secret might spill out and place the mark on my own forehead? Whatever quarrels with femininity I had I kept to myself; whatever handicaps femininity imposed, they were mine to deal with alone, for there was no womens movement to ask the tough questions, or so brazenly disregard the rules.Femininity, in essence, is a romantic sentiment, a nostalgic tradition of imposed limitations. Even as it hurries forward in the 1980s, putting on lipstick and high heels to appear well dressed, it trips on the ruffled petticoats and hoopskirts of an era gone by. Invariably and necessarily, femininity is something that women had more of in the past, not only in the historic past of prior generations, but in each womans personal past as wellin the virginal innocence that is replaced by knowledge, in the dewy cheek that is coarsened by age, in the inherent nature that a woman seems to misplace so forgetfully whenever she steps out of bounds. Why should this be so? The XX chromosomal message has not been scrambled, the estrogen-dominated hormonal balance is generally as biology intended, the reproductive organs, whatever use one has made of them, are usually in place, the breasts of whatever size are most often where they should be. But clearly, biological femaleness is not enough.Femininity always demands more. It must constantly reassure its audience by a willing demonstration of difference, even when one does not exist in nature, or it must seize and embrace a natural variation and compose a rhapsodic symphony upon the notes. Suppose one doesnt care to, has other things on her mind, is clumsy or tone-deaf despite the best instruction and training? To fail at the feminine difference is to appear not to care about men, and to risk the loss of their attention and approval. To be insufficiently feminine is viewed as a failure in core sexual identity, or as a failure to care sufficiently about oneself, for a woman found wanting will be appraised (and will appraise herself) as mannish or neutered or simply unattractive, as men have defined these terms.We are talking, admittedly, about an exquisite esthetic. Enormous pleasure can be extracted from feminine pursuits as a creative outlet or purely as relaxation; indeed, indulgence for the sake of fun, or art, or attention, is among femininitys great joys. But the chief attraction (and the central paradox, as well) is the competitive edge that femininity seems to promise in the unending struggle to survive, and perhaps to triumph.In the first two paragraphs, the author describes experiences from her girlhood and early adulthood primarily toA.
