A train traveled 1/4 of the distance between two cities in 2/3 of an hour. at this rate, what fraction of the distance can the train travel in one hour

Answers

Answer 1
Answer:   3/8

====================================================

Explanation:

A = fraction of the distance traveled in 2/3 of an hourB = time value that pairs up with AC = fraction of the distance traveled in 1 hourD = time value that pairs with C

In this case,

A = 1/4B = 2/3C = unknownD = 1

We can set up the proportion

A/B = C/D

Which cross multiplies to

A*D = B*C

Let's plug in the known values and solve for C

A*D = B*C

(1/4)*(1) = (2/3)*C

1/4 = (2/3)*C

(2/3)*C = 1/4

3*(2/3)*C = 3*(1/4) ..... multiply both sides by 3

2C = 3/4

(1/2)*2C = (1/2)*(3/4) .... multiply both sides by 1/2

C = (1*3)/(2*4)

C = 3/8

The train travels 3/8 of the distance in 1 hour.

The population of deer in a forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 percent per year.

Based on this prediction, about how many years will it take for the population to double in size?

Use the equation P = P.(1 + r)

in which Po represents the initial population size, rrepresents the growth rate, trepresents the number

of years, and Prepresents the final population size.

A.

5.0 years

B.

1.8 years

OC. 0.3 year

OD.

3.8 years

Answers

Answer:

35 years

Step-by-step explanation:

Given that:

Current deer population, P0 = 800

Growth rate = 20% yearly

For the population to double in size, P = 2 * P0 = 2 * 800 = 1600

t = number of years

Using the relation :

P =P0(1 + r)^t

1600 = 800(1 + 0.2)^t

1600 / 800 = (1.02)^t

2 = (1.02)^t

t = log2 / log(1.02)

t = (0.3010299 / 0.0086001)

t = 35.003069

t = 35 years

A washer and dryer cost $711 combined the washer cost $61 more than the dryer what is the cost of the dryer

Answers

Answer:

$325

Step-by-step explanation:

Let  the dryer be x and the washer be y

x+y= 711---------1

y= x+61-----------2

put y= x+61 in 1

x+x+61= 711

2x+61= 711

2x= 711-61

2x=650

x= 650/2

x=325

Hence the dryer cost $325

3x+16=7x


answer please

Answers

Answer:

x = 4

Step-by-step explanation:

We have the algebraic expression 3x + 16 = 7x and are asked to solve.

When we need to solve for x, we need to get x alone always.

So 3x + 16 = 7x.

Subtract 3x from both sides :

16 = 4x

Divide 4 from both sides :

x = 4

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]3x + 16 = 7x[/tex]

Step 1

Combine like terms. We move 3x to subtract 7x since we can't add with a constant with a variable.

[tex]16 = 7x - 3x \\ 16 = 4x[/tex]

Step 2

Move 4 to divide 16 because we need to make x-term as the subject of equation.

[tex] \frac{16}{4} = x \\ 4 = x[/tex]

Step 3

If you are not sure that the answer is correct, we can check the answer by substituting x = 4 in the equation.

[tex]3x + 16 = 7x \longrightarrow 3(4) + 16 = 7(4) \\ 12 + 16 = 28 \\ 28 = 28[/tex]

The equation is true for x = 4. Hence, the solution is x = 4

Samantha wants to buy a house and plans to rent the apartment located in the basement for extra income. The house has a purchase price of $200,000 and she will make a 10% down payment. Samantha has qualified for a 30 year mortgage with a fixed rate of 5.875%. Approximately how much rent should she charge for the apartment in order to cover her monthly mortgage payment if she only wants to spend $500 a month of her own money?

Answers

Answer:

$567.07

Step-by-step explanation:

Given that :

Purchase price = $200,000

Number of years = 30

Rate = 5.875%

Down payment = 10%

Hence, mortgage amount :

Purchase price - down payment

200,000 - (0.1 * 200000)

200,000 - 20,000

= $180,000

Using a mortgage calculator :

Mortgage amount = 180,000

Mortgage term = 30 years

Interest = 5.875%

Monthly payment will be : $1067.07

Hence, if she only wants to $500 from her own money, A rent of ($1067.07 - $500) = $567.07 will need to be charged

What is the solution for an equation?

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.

We need to find the solutions of the equation 2(x + $3.00)= $34.00 ;

Now solving for x;

2(x + $3.00)= $34.00

Open the bracket;

2x + 6 = 34

Combine the like terms;

2x = 34 - 6

2x = 28

x = 14

Therefore, the equation 2(x + $3.00)= $34.00 has only one solution which is 14.

2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team. What percentage of people attending supported the home team?

Answers

Answer:

0.29 or 29 percent I put it on god

Step-by-step explanation:

The percentage of people attending supported the home team is 29%.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, 2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team.

From the general formula of percentage:

percentage = value/ total value * 100

Since, Out  of 2400 only 696 supported the home team

thus,

Percentage = 696/2400*100

Percentage = 29%

Therefore, 29% percentage of people attending supported the home team.
