Alicia's mp3 player contains 1260 songs. Given that 35% of the songs are rock songs and 20% are rap songs, how many of the songs are other type of songs?

Answers

Answer:

 There are 567 of the songs are other.

Step-by-step explanation:

Since 55% of the songs are rock and rap, 45% of the songs are other.

To find 45% of 1260 we multiply by the decimal:

1260 x 0.45 = 567

The answer is 567

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: Rock and rap songs make 55% of the songs then the rest of the songs should make 45% of the total songs.

Thus we have 45% of 1260=567

Hence, The answer is 567

7/8 students own a bike . 72 is the difference between the ones that own a bike and ones that do not. how many were surveyed?

Answers

x + y is the number of students who were surveyed. x is the number who own a bike. y is the number who don't. the ratio of the ones who own a bike and the ones who were surveyed is x / (x + y) that ratio is 7/8. you get x / (x + y) = 7/8 multiply both sides of this equation by (x + y) to get x = (x + y) * 7/8 simplify to get x = 7/8 * x + 7/8 * y subtract 7/8 * x from both sides of this equation to get: 1/8 * x = 7/8 * y solve for x to get x = 7 * y this means that the number of students who own a bike is 7 times the number of students who don't. divide both sides of that equation by y to get x/y = 7/1. that means that the ratio of students who own a bike to the number of students who don't is equal to 7/1. the problem states that the difference between the number who own a bike and the number who don't is 72. this means that x - y = 72 from the equation of x = 7 * y, replace x with 7 * y in the equation of x - y = 72 to get: 7 * y - y = 72 simplify to get 6 * y = 72 divide both sides of that equation by 6 to get y = 72/6 = 12 this means that the number of students who do not own a bike is 12. since x = 7 * y, then x = 7 * 12 = 84. this means that the number of students who own a bike is 84. since the number of students is x + y, this means that the number of students who were surveyed is 84 + 12 = 96. let's see if this is right. 96 students were surveyed. 84 own a bike and 12 don't. the difference between the ones who own a bike and the ones who don't is 84 - 12 = 72. the ratio of the ones who own a bike and the number surveyed is 84/96 = 7/8. solution is 96 students were surveyed.
The answer is 96 students were surveyed

A spider traveled 20 feet in 12 minutes. At this rate, how far could it travel in 3 minutes Distance ( ft ) 20 | | | Time (min) 12 | | 3|

Answers

It could travel 5 feet in 3 minutes because 12minutes/4 is three minutes and 20feet/4 is 5 feet.

The spider's average speed is 5/3 feet per minute, so in 3 minutes it could travel 5 feet.

To solve how far a spider could travel in 3 minutes based on its rate of 20 feet in 12 minutes, we use the concept of proportional relationships. The average speed of the spider can be calculated first.

The average speed is found by dividing the total distance by the total time. So, the spider's average speed is:

20 feet / 12 minutes = 5/3 feet per minute.

To find out how far the spider could travel in 3 minutes at this speed, we multiply the average speed by the time:

(5/3 feet per minute) x 3 minutes = 5 feet.

Thus, the spider could travel 5 feet in 3 minutes at the same rate.

One number is 4 less than eleven times another. The sum of the two numbers is 92. Find the numbers.

Answers

The numbers are 8 and 84

8 x 11 = 88
88 - 4 = 84
84 + 8 = 92
Final answer:

The problem is an algebraic one involving two linear equations. By setting up correct equations, solving them step-by-step, we find that the two numbers are 8 and 84.

Explanation:

This problem falls under algebra and specifically it involves solving linear equations. Let's denote the two unknown numbers as x and y. Given that 'One number is 4 less than eleven times another' we can formulate the first equation like this: y = 11x - 4. The second piece of information given is 'The sum of the two numbers is 92', so the second equation is x + y = 92.

We can substitute y from the first equation to the second equation which gives us: x + 11x - 4 = 92. Simplifying this gives us: 12x - 4 = 92. Solving for x we add 4 to both sides to get 12x = 96, and then divide both sides by 12 to find that x = 8.

Now that we have found x, we can substitute it back to one of the initial equations to find y. Substiting x = 8 into the equation y = 11x - 4 we find that y = 84. So the two numbers we are looking for are 8 and 84.

The family members going are 4 mothers, 4 grand-mothers and 4 daughters. What will be the minimum number of tickets required?

Answers

Final answer:

The minimum number of tickets required for the family members is four because the individuals can be counted in multiple categories—each person can be a daughter, mother, and grandmother.

Explanation:

The question is asking for the minimum number of tickets required for a group consisting of 4 mothers, 4 grandmothers, and 4 daughters. To solve this problem, we need to consider how these individuals could be related to each other and overlap in these categories. In a possible scenario, each grandmother is also a mother, and each mother is also a daughter. Therefore, the minimum number of individuals who could cover all these roles is four: one individual who is a daughter, her mother (who is also a daughter to the next in line), her grandmother (who is the mother of the previous person), and her great-grandmother (who fills the role of the fourth grandmother).

Final answer:

To determine the minimum number of tickets required for a group consisting of 4 mothers, 4 grandmothers, and 4 daughters, we have to identify overlapping roles within a three-generation family structure. By recognizing that each person can hold multiple roles, we find that a minimum of 3 tickets is required for this group.

Explanation:

The question asks to calculate the minimum number of tickets required for a group including 4 mothers, 4 grandmothers, and 4 daughters. We need to figure out the possible relationships and overlaps in this family structure.

Let's consider a scenario where each grandmother is also a mother, and each mother is also a daughter. This is possible if we are speaking about a family consisting of three generations: the oldest generation (the grandmothers who are also mothers to the middle generation), the middle generation (the mothers who are also daughters to the oldest generation and mothers to the youngest generation), and the youngest generation (the daughters). If we set it up this way, we can have the smallest number of individuals who meet all the necessary conditions.

Here is the step-by-step explanation of the generational setup:

First generation: 1 grandmother who is also a mother.Second generation: Her daughter, who is also a mother.Third generation: Her daughter, who is not a mother.

Thus, the three women in this family structure account for all 4 grandmothers, 4 mothers, and 4 daughters. Therefore, the minimum number of tickets required for this group would be 3.

how can you identify a linear nonproportional relationship from a table, a graph, and an equation?

Answers

Final answer:

A linear nonproportional relationship can be identified from a table by a consistent change in the dependent variable with a non-zero y-intercept, in a graph as a straight line with a constant slope that does not pass through the origin, and in an equation by the form y = mx + b or y = a + bx with a non-zero y-intercept.

Explanation:

To identify a linear nonproportional relationship from a table, a graph, and an equation, one must understand the characteristics of such a relationship. A linear nonproportional relationship is defined as a relationship where the rate of change between the variables is constant, but the ratio of the dependent variable to the independent variable is not constant.

From a table, a linear nonproportional relationship is identified by a consistent change in the dependent variable as the independent variable changes, but the starting value is not through the origin (0,0); there is a non-zero y-intercept.

In terms of a graph, it would appear as a straight line that does not pass through the origin but has a consistent slope. The slope of the line represents the rate of change, while the point where the line crosses the y-axis represents the y-intercept, which is not zero.

A linear nonproportional equation typically takes the form y = mx + b or y = a + bx, where m or b is the slope and b or a is the y-intercept. To recognize nonproportionality, check if the y-intercept (b or a) is not zero.

The depth of the dig of a tree that is 17 feet high will be 10.20 feet.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Jack was establishing a tree. He needed to dig an opening that was 3 feet deep for every 5 feet of tree height.

The ratio of the length of the tree and the depth of the dig will remain constant.

Let 'd' be the depth of the dig for 17 feet tree. Then the equation is given as,

5 / 3 = 17 / d

d = (17 x 3) / 5

d = 51 / 5

d = 10.2 feet

24.2 / 0.2 can someone explain please?

Answers

When dividing decimals, you move them over until the denominator is a whole number, so 0.2 to 2. The divisor's decimal is also moved over, so 24.2 to 242.

Now we have 242/2. I think you can take it from there. 

To calculate 24.2 divided by 0.2, convert the division into a multiplication by recognizing that dividing by 0.2 is the same as multiplying by 5. Thus, 24.2 times 5 gives the result of 121.

To calculate the quotient of 24.2 divided by 0.2, you can follow these steps:

First, recognize that dividing by 0.2 is the same as multiplying by 5. This is because 1 divided by 0.2 equals 5 (since 0.2 is the same as 1/5).Therefore, you can convert the division problem into a multiplication one: 24.2 × 5.Finally, when you multiply 24.2 by 5, you get 121. This is your answer.

Bonita deposited $1300 into a bank account that earned 5.75% simple interest each year. She earned $299 in interest before closing the account.
If no money was deposited into or withdrawn from the account, for how many years was the money in the account?
Round your answer to the nearest whole year.

Answers

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

where

I is the amount in interest

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=?\ years\\ P=\$1,300\\ I=\$299\\r=0.0575[/tex]

substitute in the formula above  and solve for t

[tex]299=1,300(0.0575)(t)[/tex]

[tex]t=299/[1,300(0.0575)][/tex]

[tex]t=4\ years[/tex]

therefore

the answer is

[tex]4\ years[/tex]


Bonita's money was in the account for approximately 5 years.

Step 1: Define Variables and Formula

Let:

P represent the principal amount deposited (initial amount - $1300).r represent the annual interest rate (5.75% - we can convert this into a decimal by dividing by 100: 0.0575).t represent the number of years the money was in the account (unknown).I represent the total interest earned ($299).

The formula for simple interest is:

I = P × r × t

Step 2: Apply the Formula to Known Values

We are given the values for I, r, and P (we can solve for P using the given information). Let's plug these values into the formula:

$299 = P × 0.0575 × t

Step 3: Solve for the Unknown (t - Number of Years)

To isolate t (the number of years), we can divide both sides by the product of P and r. However, we don't have the value of P yet.P needs to be the initial principal amount before any interest is earned. Since the question states Bonita deposited $1300, and we're calculating the interest earned, P represents the principal amount before interest.

Step 4: Find the Principal Amount (P)

The total amount Bonita received when closing the account is the principal amount (P) plus the interest earned (I). We can represent this as:

P + I = $1300 (deposit amount) + $299 (interest)P = $1300 + $299P = $1599 (This is the principal amount before interest)

Step 5: Solve for the Number of Years (t)

Now that we know P, we can plug it back into the equation along with the interest rate (r) to solve for t:

$299 = $1599 × 0.0575 × tt ≈ 5.49 (We haven't rounded yet)

Step 6: Round the Answer (Nearest Whole Year)

The question asks for the number of years rounded to the nearest whole year. Since the decimal part (0.49) is closer to 0 than 1, we round down.
