An object has a mass of 175 g and a volume of 25 cm3.
Find the density of the object in g/cm3.

Answer:0.04

Step-by-step explanation:

The United States has a population of about 320 million, so if homicides were proportional to Honduras' rate of homicide, we would expect about 12,800 deaths due to homicides in the United States.

This is calculated by taking the population of the United States (320 million) and multiplying it by the Honduras' homicide rate of 40 per 100,000 people.


To calculate this, we first need to find Honduras' homicide rate. The World Bank has this information, which states that the rate is 40 per 100,000 people. We then need to take the population of the United States (320 million) and multiply it by the rate.

This equals 128 million homicides per 100,000 people in the United States. This comes out to 12,800 deaths due to homicides in the United States. Round this to the nearest person, and you get 12,800.

The scale of the map is 1:2, the distance from Averton to Charlbrough is 12 kilometers, and the distance in the map is 6.25 cm.

We know that 25 kilometers are represented in the map using only 12.5 centimeters. Now, let's simplify this:

25 kilometers / 12. 5 cm = 2

This can be expressed as a scale of 1:2 in which each centimeter represents 2 kilometers.

We know the distance on the map is 6 cm, let's now convert this to kilometers:

6cm x 2 = 12 kilometers

The solution of the system of linear equations determines if the system has no solution, one solution, or an infinite number of solutions

2·x - 3·y = 3 and -4·x + 6·y = 6

3·x - 2·y = 3 and x + 2·y = 5

-8·x + 12·y = -12 and 2·x - 3·y = 3

y = -x + 2 and y = 3·x - 2

A system of equations is a set of two or more equations that are formed by the same variable.

Each of the equations are solved as follows to determine whether it has no solution, one solution, or an infinite number of solutions

1. 2·x - 3·y = 3 and -4·x + 6·y = 6

Multiplying the first equation by 2, we get; 4·x - 6·y = 6.

Adding the above equation to the second equation,we get;

4·x - 6·y + (-4·x + 6·y) = 6 + 6 = 12

0 = 12 (False)

Therefore, the system has no solution

2. 3·x - 2·y = 3 and x + 2·y = 5

Adding the two equations, we get;

3·x - 2·y + (x + 2·y) = 3 + 5 = 8

4·x = 8

x = 8/4 = 2

Substituting x = 2 into the second equation, we get;

x + 2·y = 5

2 + 2·y = 5

2·y = 5 - 2 = 3

y = 3/2 = 1.5

y = 1.5

Therefore, the system has one solution

3. -8·x + 12·y = -12 and 2·x - 3·y = 3

Multiplying the second equation by 4, we get; 8·x - 12·y = 12

Adding the product of the second equation and 4 to the first equation we get;

8·x - 12·y + (-8·x + 12·y) = 12 + (-12) = 0

0 = 0

Therefore, the system has infinite number of solutions

4. y = -x + 2 and y = 3·x - 2

Substituting y = -x + 2 into the second equation, we get;

-x + 2 = 3·x - 2

3·x - 2 = -x + 2

3·x + x = 2 + 2 = 4

4·x = 4

x = 4/4 = 1

x = 1

y = -x + 2

y = -1 + 2 = 1

y = 1

Therefore, the system has one solution.

Therefore, the first system has no solution, the second system has one solution, the third system has an infinite number of solutions, and the fourth system has one solution.

Therefore, Dylan's initial investment was £1200.

Simple interest is a type of interest that is calculated on the principal amount of a loan or investment. It is a fixed percentage of the original amount borrowed or invested that is added to the principal at regular intervals, usually monthly, quarterly or annually. The interest rate remains constant throughout the loan or investment term, and the interest earned or paid is calculated solely on the initial principal amount. Simple interest is commonly used for short-term loans or investments, and the formula for calculating it is straightforward:

by the question.

we can start by using the formula for simple interest:

Simple interest = Principal x Rate x Time

Where the Principal is the initial investment, the Rate is the annual interest rate, and the Time is the number of years.

We know that the Rate is 3% per annum and the Time is 2 years, so we can write:

Simple interest = Principal x 0.03 x 2

Since we are given that the value of the investment increased by £72 at the end of the 2-year period, we can set up an equation:

Value of investment - Initial investment = Simple interest

£72 = Principal x 0.03 x 2

£72 = Principal x 0.06

Principal = £72 / 0.06

Principal = £1200

There can be 78,364,164,096 different license plates created if there are 7 numbers or letters on the plate, determined using the product rule.

We can use the product rule to determine the number of different license plates that can be created if there are 7 numbers or letters on the plate.

Assuming that each position on the license plate can be filled with any number or letter, we can use the multiplication principle to find the total number of possibilities. For each position, there are 26 letters and 10 digits to choose from (assuming the use of the English alphabet), so there are 36 choices for each position.

Therefore, the total number of different license plates that can be created is:

36 x 36 x 36 x 36 x 36 x 36 x 36 = 36^7

This simplifies to:

If there are total 160 girl students in the total number of students in the college and ratio of boys to girls is 8: 5. Then total number of students in college is equals to the 416.

In a college, the ratio of the number of boys to girls = 8 : 5, so, total ratio is 13.

Number of girl students in the total number of students in the college = 160

We have a goal here to determine the total number of students in the college.

First of all, assume x be any number such that the number of girls and boys are

Number of girls= 5x

Number of boys = 8x

Total number of students in college= 13x

But total girls in college = 160 , so 5x= 160

solve the above expression (dividing by 5)=> x = 160/5 = 32

So, total boys students in college = 8x

= 8 × 32

b. For y2 ≤ y1 ≤ 10 of y2 is the conditional density f(y1|y2) is defined

(a) To find the marginal density function for Y2, we integrate the joint pdf over all possible values of Y1:

fY2(y2) = ∫fY1,Y2(y1,y2) dy1, where the integral is taken over the range where 0 ≤ y2 ≤ y1 ≤ 10, otherwise 0.

fY2(y2) = ∫₀¹⁰3y1 dy1 = 1.5y² |₀y2 = 1.5y2², where 0 ≤ y2 ≤ 10.

So the marginal density function for Y2 is:

fY2(y2) = 3y2², where 0 ≤ y2 ≤ 10.

(b) The conditional density f(y1|y2) is defined as:

f(y1|y2) = fY1,Y2(y1,y2) / fY2(y2), where fY2(y2) > 0.

The inequality that describes the problem when coach Yamada is organizing community volleyball teams is x ≤ 9.

Why is x ≤ 9 the correct inequality that describes the problem when coach Yamada is organizing community volleyball teams? Here is why: We know that coach Yamada wants each team to have 8 players but he can't make as many full teams as he wanted to because fewer than 80 people signed up.

Let x represent the number of full teams coach Yamada can make. We know that 1 team can have 8 players. Therefore, the number of players needed for x full teams = 8xWe also know that fewer than 80 people signed up. So, 8x < 80, if more than 80 people signed up then coach Yamada would be able to make more than x full teams.

Since coach Yamada can't make a fraction of a team so x should be an integer. Therefore, the solution for 8x < 80 is x ≤ 9.Therefore, x ≤ 9 is the inequality that describes the problem when coach Yamada is organizing community volleyball teams.

Part A

The volume of solution A is represented as a fraction, so we need to convert it to a decimal number. To do this, we set up a long division problem with the numerator (the top number in the fraction) as the dividend and the denominator (the bottom number in the fraction) as the divisor. So the dividend is 1, and the divisor is the volume of solution A.

Part B

No, we cannot divide 2 by 9 evenly because they are not divisible without a remainder.

Part C

Since we cannot divide 2 by 9 evenly, the first digit of the quotient will be 0.

Part D

We set up the long division problem as follows:

The decimal equivalent of 2/9 is 0.27777... (repeating). We can see that the division process continues indefinitely with the same repeating pattern, so we use an ellipsis to indicate that the pattern continues infinitely.

Part E

If we keep repeating the long division process for 2/9, we will continue to get the same repeating decimal pattern of 0.27777..., with no end in sight.

Part F

The volume of solution B is represented as the fraction 3/8, so we need to convert it to a decimal number. To do this, we set up a long division problem with the numerator (3) as the dividend and the denominator (8) as the divisor.

Part G

No, we cannot divide 3 by 8 evenly because they are not divisible without a remainder.

Part H

Since we cannot divide 3 by 8 evenly, the first digit of the quotient will be 0.

Part I

We set up the long division problem as follows:

 0.3 7 5

The decimal equivalent of 3/8 is 0.375. We can see that the division process terminates after a finite number of decimal places.

Part J

If we keep repeating the division process for 0.375, we will always get the same decimal number because the process terminates and doesn't involve any repeating pattern.

Part K

The volume of solution C is represented as the fraction 1/5, so we need to convert it to a decimal number. To do this, we set up a long division problem with the numerator (1) as the dividend and the denominator (5) as the divisor.

Part L

No, we cannot divide 1 by 5 evenly because they are not divisible without a remainder.

Part M

Since we cannot divide 1 by 5 evenly, the first digit of the quotient will be 0.

A function's range can be used to describe one of two related ideas: The function's codomain a representation of the action A binary relation f between two sets X and Y is a function if there is exactly one y in Y such that f connects x to y for every x in X.

Here, we have

Given: A graph with the x-axis labeled Temperature in Degrees, with intervals 60 to 69, 70 to 79, 80 to 89, 90 to 99, 100 to 109, 110 to 119. The y-axis is labeled Frequency and begins at 0 with tick marks for every unit up to 14.

We have to determine which measure of variability should be used for both sets of data to determine the location with the most consistent temperature.

We concluded that Range because it measures the difference between the highest and lowest values in a dataset, provides a clear measure of variability for both sets of data. It is not affected by skewness or symmetry, which makes it a useful measure of variability for comparing the temperature consistency between Beach Town and Sunny Town.
