Explanation:
A collection of quarters, dimes, and nickels is worth $5.00. If the ratio of quarters to dimes is 2:4:7, how many quarters are there ?
Answer:
8 quarters
Explanation:
Let's look at the ratio first off.
2 quarters: 4 dimes: 7 nickels
Let's write it in terms of money
50 cents of quarters: 40 cents of dimes: 35 cents of nickels
If we add up all the cents then we get $1.25
Then, if we divide $5 by $1.25 we get 4.
You should then multiply the original ratio by 4:
8 quarters: 16 dimes: 28 nickels
Let's check this by turning it to money:
$2: $1.60: $1.4
This all adds up to $5
Therefore your answer is 8 quarters.
Hope this helps!

There are $0.769 worth of quarters in the collection.
How do we solve word problems with ratios?Word problems with ratios are being solved by adding the ratios together, then relating that portion we are expected to determine to the sum total of the added ratio.
Mathematically, from the given information, we have:
The total worth of the collection = $5.00In the same order of quarters, dime, and nickels, the ratios are 2:4:7The sum total of these ratios are;
= 2 + 4 + 7
= 13
Now, the number of quarters in the whole collection can be computed as:
[tex]\mathbf{= \dfrac{2}{13}\times \$5}[/tex]
[tex]\mathbf{= \dfrac{2}{13}\times \$5 } \\ \\ \\ = \mathbf{\$0.769}[/tex]

Define the word "incognito"?
Answer:
(Of a person) Having ones true identity concealed
Answer:
When you wish to accomplish something without being seen, become incognito, which means concealing your actual identity. It's ironic that the terms recognize and incognito are both connected to the Latin verb cognoscere, which means "to learn," because you don't want to be recognized while you're doing anything incognito.

Question #2MultipleChoice
must be considered carefully because it controls how information is revealed.
Dialogue
Transitions
Point of view
Word choice
Answer:
The correct answer is C) Point of View
Explanation:
As far as communication is concerned, the Point of View refers to the point of view from which a person delivers their information. The wrong point of view may shortcircuit the process of information transmission.
Effective communication entails deciding what as well as how, when, and to whom it will be communicated. The best forms of communication take very careful consideration of the recipient's point of view or paradigm.
For example, a doctor who has just rushed his sick son to the hospital, in response to a question about his whereabouts, may tell his friend that he is just returning from the hospital.
Now, if he doesn't give the right perception, the friend may think he is just returning from a duty call and may treat the remainder of the evening casually or as usual.
But imagine that he says,
"my son asphyxiated and I had to rush him to the hospital. My colleagues did great work of stabilizing him. I'm just going back home to freshen up. I'll be staying with him for the next 6-9 hours for which he would be under observation."
This would completely change the dynamics of the next questions and comments by the doctor's friend.
In the second response, the doctor has taken into consideration the fact that his friend knows him to be a doctor and takes for granted that he must frequent the hospital every day whilst he is on duty and that sometimes even when he is on leave, and there is a case that requires his urgent attention, he must visit the hospital.
So he has to deliberately communicate the reason why he went to the hospital and that is where the paradigm shifts.

WHY DO CATS PURR ASAP I WILL MARK BRAINLIEST IF YOU DO TEN SENTENCES
50 POINTS
Answer:
Purring is a kind of defence mechanism, and a way for your cat to remain calm when they're stressed . Just as your cat's purring can make you feel calmer, it helps to soothe them too. That's why a lot of cats purr on the vet's table - even when they aren't happy. Purring is more than just a method of non-verbal communication.
Explanation:
Answer:
Although we assume that a cat's purr is an expression of pleasure or is a means of communication with its young, perhaps the reasons for purring can be deciphered from the more stressful moments in a cat's life. Cats often purr while under duress, such as during a visit to the veterinarian or when recovering from injury. Thus, not all purring cats appear to be content or pleased with their current circumstances. This riddle has lead researchers to investigate how cats purr, which is also still under debate. Scientists have demonstrated that cats produce the purr through intermittent signaling of the laryngeal and diaphragmatic muscles. Cats purr during both inhalation and exhalation with a consistent pattern and frequency between 25 and 150 Hertz. Various investigators have shown that sound frequencies in this range can improve bone density and promote healing. Cats have adapted to conserve energy via long periods of rest and sleep, it is possible that purring is a low energy mechanism that stimulates muscles and bones without a lot of energy. Perhaps cats' purring helps alleviate the dysplasia or osteoporotic conditions that are more common in their canid cousins. Although it is tempting to state that cats purr because they are happy, it is more plausible that cat purring is a means of communication and a potential source of self-healing.
Short answer: Cats purr as a way to calm themselves, to communicate, self-heal.
