Answer:

7.5 liters of a 40% sugat solution

Step-by-step explanation:

Let

x------> liters of a 40% sugar solution

remember that

40% = 40/100 = 0.40

60% = 60/100 = 0.60

56% = 56/100 = 0.56

we know that the amount of liters of a 40% sugar solution (x) multiplied by 0.40 plus the amount of liters of a 60% sugar solution (30 L) multiplied by 0.60 must be equal to the total amount of liters mixed (x+30) multiplied by 0.56

0.40x + 0.60(30) = 0.56 (x+30)

solve for x

0.40x + 18 = 0.56x +16.8

0.56x - 0.40x = 18 -16.8

Your answer would be
7.5 liters of 40%

They have also noticed that some of their friends seem to be disappering. bob wonders if the two are related...

A). 20% C). 2%
B). 25% D). 5%

The answer would be 20%
If you subtract 450 and 360 you would get 90. So basically you do 90 divided by 450 and move the decimal point twice

Chris has finished 30% of an art project that has taken him a total of 9 hours so far. If he continues to work at the same rate, how many hours will it take for him to complete the entire project?

Answers

there was already a question like this on here so i’m going off the answer already given: 30 hours, i hope it’s right

If Chris has finished 30% of an art project in 9 hours then he will take 30 hours to complete the whole work if he will work at same rate.

What is rate?

A measure, quantity, or frequency, typically one measured against some other quantity or measure.

How to calculate time?

Let the project contains 100 questions in total.

Chris finished 30% questions so he may finish 30 questions in 9 hours.

So in order to complete the 1 question he took =9/30 hours

In order to complete 100 questions he will take 9/30*100 hours which is equal to 30 hours.

Hence Chris will take 30 hours to complete the project.

Keisha has 45 coins in her piggy bank, consisting of only nickels, dimes and quarters. She has one fewer nickel than she has dimes, and one fewer quarter than three times her number of nickels. How many nickels does she have?

Answers

Answer:

20 nickels, 40 dimes, and 8 quarters

Step-by-step explanation:

This is a system of three equations with three unknowns. Let x = # of nickels, y = # of dimes, and z = # of quarters.

x + y + z = 68 (since there are 68 total coins)

.05x + .10y + .25z = 7

.10x + .05y + .25z = 6 (if the nickels were dimes and the dimes were nickels)

Multiply both sides of the last two equations by 100 to simplify, giving us:

5x + 10y + 25z = 700 or x + 2y + 5z = 140 if you divide both sides by 5.

10x + 5y + 25z = 600 OR 2x + y + 5z = 120 if you divide both sides by 5.

Let's solve the first equation for x. That gives us x = 68 - y - z. We can substitute this result into each of the final two equations to create a system of two equations with two unknowns, which is easier to solve. For the first equation:

(68 - y - z) + 2y + 5z = 140

68 + y + 4z = 140 or y + 4z = 72

For the second equation, we have:

2(68 - y - z) + y + 5z = 120

136 - 2y - 2z + y + 5z = 120

136 - y + 3z = 120

-y + 3z = -16

Now we have our system of two linear equations:

y + 4z = 72

-y + 3z = -16

If we add those two equations together, then we get 7z = 56 or z = 8. If z = 8, we can substitute this into either of the two previous equations. Let's choose the first. This gives us:

y + 4(8) = 72 or y + 32 = 72.

So y = 40. If y = 40 and z = 8, then we know:

x = 68 - y - z = 68 - 40 - 8 = 28 - 8 = 20.

Consequently, there were 20 nickels, 40 dimes, and 8 quarters in the piggy bank.

Choose the best answer to fill in the blanks. When writing for business, it is important to be _______ and make sure that you always use ______ emphasis. Have you ever thought about how the media might influence our opinions about ourselves? Images in magazines and on television create an idealized picture of what a beautiful woman should look like in our society. Young women are bombarded by these images every day. As a result, they grow from adolescence into adulthood with an unrealistic picture of beauty in their minds. This distorted view of reality is extremely dangerous for the female psyche. The average woman in the United States is a size 1214; however, runway and fashion models are often a size zero. The unrealistically thin portrayal of women is concerning. Some models and actresses are even speaking out about their frustrations with the portrayal of women in magazines. Actress Kate Winslet, famous for her role in the movie Titanic, complained about an image of her published in a magazine in which her body was digitally stretched to look thinner. She stated, "The retouching is excessive. I don't desire to look like that." Winslet went on to express her concerns about the unrealistic and unhealthy message that digital altering of images creates in the female mind. The images in magazines are the result of the effects of special lighting, makeup, and even image editing tools like Photoshop. Even the images of the world's most beautiful supermodels are altered to make the models appear taller, thinner, or otherwise, different from their original pictures. If even the models' images are altered, how is the average woman supposed to feel about her own beauty?1Select ALL the correct answers.Which two sentences should be added to the end of paragraph 3 to support the idea that photo editing in magazines can affect readers' self-esteem? The unrealistic images could lead young, impressionable readers to make unhealthy choices in pursuit of physical beauty that is not even real. More actresses should speak out and let their fans know when pictures of them have been digitally altered by image-conscious magazines. Knowing that magazines edit photos of models helps magazine readers understand that they could also look that way if their photos are retouched. Models and their agents should know better than to allow magazines to digitally retouch images, which inaccurately portrays individuals. Magazine publishers consistently claim they are simply keeping up with the latest advancements in digital photo technology. Constantly seeing these flawless pictures makes normal people feel like they do not measure up to the current standard of beauty.
