Christina has 50 coins consisting of quarters and dimes. The coins combined value is $9.50. Write a system of equation to determine how many quarters and dimes Christina has.

Answers

Answer:

Christina has 30 quarters and 20 dimes.

Step-by-step explanation:

Given that a quarter is worth 0.25 dollars and a dime is worth 0.10 dollars, if Christina has 50 coins and these add up to a total of $ 9.50, to determine the number of quarters and dimes that she has in her possession, the following calculation must be carried out, taking into account that the difference between a quarter and a dime is 0.15 dollars:

50 x 0.25 = 12.5

12.5 - 9.5 = 3

Thus, the difference between the value that Christina has and the value that she would have if all of her coins were quarters is 3 dollars. Thus, since 0.15 x 20 equals 3, of the 50 coins Christina has, 30 are quarters and 20 are dimes.

This is confirmed through the following equation:

30 x 0.25 + 20 x 0.1 = X

7.5 + 2 = X

9.5 = X

Genna purchased a pair of shoes on a web site.The original price of the shoes was $120. She used the coupon code to receive a 20% discount. The web applied a 15% service fee to the discounted price. Genna's shoes were less than the original price by what percent

Answers

Answer:

$116

Step-by-step explanation:

the total discount is 20-15 = 5%

the dicount = (5*120)/100 = $4

So she bought it with price = 120 - 4 = $116

Answer: 8%

Step-by-step explanation:

1. Apply the discount to the original price

20% of 120 (0.2*120) is 24, thus Genna saves 24 dollars

120-24 = 96 (the new price of the shoes, with the coupon applied)

2. Apply the service fee to the discounted price

15% of 96 (0.15*96) = 14.4

This number is the amount of money being added to the discounted price, as it is an additional fee

96 + 14.4 = 110.4

3. Find the percent discount Genna's shoes are using the new price.

1 - (New price/Old price) = Percent discount

110.4/120 = 0.92

1 - 0.92 = 0.08

The shoes are 92% of the original price. Thus, the shoes are 8% less than the original price.

Step-by-step explanation:

the letters of the word independent are written on individual card and the cards are put into a box a card is selected and then replaced and then a second card is selected find the probality of obtaining​ the letter p twice

Answers

Answer:

The probability of obtaining the letter p twice is 1/121

Step-by-step explanation:

Probability of Recurring Events

There are 11 letters in the word 'independent', one of which is the letter 'p'.

When those letters are written on individual cards and they are put into a box, there are 11 different choices to pick at random.

This means the individual probability of getting a 'p' is:

[tex]\displaystyle P_1=\frac{1}{11}[/tex]

The card is reinserted into the box, leaving the sample space unaltered, thus the second card has the same probability:

[tex]\displaystyle P_2=\frac{1}{11}[/tex]

We'll use the multiplication rule. Just multiply the probability of the first event by the second.

[tex]\displaystyle P=P_1*P_2=\frac{1}{11}*\frac{1}{11}[/tex]

[tex]\displaystyle P=\frac{1}{121}[/tex]

The probability of obtaining the letter p twice is 1/121

3.78÷15=? Show the work please.

Answers

Answer:

how would you show work?

the answer is 0.252

Step-by-step explanation:

Answer:

0.252

__________________________________________________________

We have to evaluate the expression:

3.78/15

Evaluation:

We can multiply both the numerator and the denominator with the same number and that won't change the actual number since the number would cancel out

So, multiplying numerator and the denominator by 100

[tex]\frac{3.78 * 100}{15 * 100}[/tex]

[tex]\frac{378}{15 * 100}[/tex]

Since 15*25 is 375, we will rewrite the numerator as:

[tex]\frac{375 + 3}{15 * 100}[/tex]

Now, we can split it into 2 separate fractions:

[tex]\frac{375}{15 * 100}+\frac{3}{15 * 100}[/tex]

This new equation is the same as the one before as it can easily be changed to that

Since 15*25 is 375 and 3*5 is 15:

[tex]\frac{25}{100}+\frac{1}{5 * 100}[/tex]

Since 25*4 is 100:

[tex]\frac{1}{4}+\frac{1}{500}[/tex]

0.25 + 0.002

0.252

Hence, 3.78/15 is 0.252

Item 5Read the passage.The Ride of His LifeWhen Jesse Senko was 12 years old, he had an experience that literally changed his life. Senko was snorkeling while on vacation in the Cayman Islands with his family when a large sea turtle swam near him. Senko naturally did what any 12-year-old boy would do and decided to grab the turtle and go for a ride. That turtle ride, in some ways, has never ended. People find their passions in many different ways. Senko found his passion while riding on the back of a turtle when he was just 12 years old.Today, Senko is a conservation scientist at Arizona State University. He focuses his research and lifes work on marine resource sustainability. Can you guess what that includes? If you guessed sea turtles, you would be correct. In college, Senko majored in fisheries and wildlife science, and he also received a Master of Science degree in wildlife ecology. Much of the focus of his work is on saving endangered sea turtles.Sea turtles help keep the ocean healthy, and thus their well-being affects the entire ecosystem. They provide a natural regulatory system for the environment. For example, sea turtles eat seagrass, which helps it grow properly, and their unhatched eggs provide nutrients for plant life to keep beaches healthy. Sea turtles also provide a home for small animals that attach to their shells.Sea turtles are endangered because fishermen inadvertently catch them in their nets, which can cause the turtles irreparable harm. Senko came up with the idea to create solar-powered fishing nets so fishermen can readily see when they accidentally catch a sea turtle. Because the lights are solar powered, the fishermen do not have to maintain the lights or change the batteries. This technology has resulted in a 65 percent reduction in sea turtle catches thus far. Senkos goal is a 100 percent reduction.In "The Ride of His Life," what viewpoint is the author trying to communicate about Senko?Senko always knew his career would involve the ocean.Senko has a passion for working with sea turtles.Senko is an avid fisherman who wants to help save wildlife.Senko longs to be on the cutting edge of modern technology.
