You invest $8,000 in 3 investment accounts. The accounts are: paper, metal, and glass. Paper returns 2% income, metal returns 4% income, and glass returns 5% income. The amount invested in the glass account was double the amount invested in the metal account. The yield was a total of $280 at the end of one year. How much was invested in each account?

Answers

Answer 1

Using simple interest, the amounts invested into each account are given as follows:

Paper returns: $3,500.Metal returns: $1,500.Glass returns: $3,000.

Simple Interest

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

A(t) = P(1 + rt)

In which:

P is the initial amount.r is the interest rate, as a decimal.

The amount of interest after t years is given by:

I(t) = Prt

You invest $8,000 in 3 investment accounts, hence:

[tex]P_1 + P_2 + P_3 = 8000[/tex]

From the rates of the account, we have that:

[tex]I_1 = 0.02P_1[/tex][tex]I_2 = 0.04P_2[/tex][tex]I_3 = 0.05P_3[/tex]

The amount invested in the glass account was double the amount invested in the metal account, hence:

[tex]P_3 = 2P_2[/tex]

The yield was a total of $280 at the end of one year, hence:

[tex]I_1 + I_2 + I_3 = 280[/tex]

[tex]0.02P_1 + 0.04P_2 + 0.05P_3 = 280[/tex]

From the first and the third equations, we have that:

[tex]P_1 + P_2 + P_3 = 8000[/tex]

[tex]P_1 + 3P_2 = 8000[/tex]

[tex]P_1 = 8000 - 3P_2[/tex]

Hence the amount of the metal investment can be found as follows:

[tex]0.02P_1 + 0.04P_2 + 0.05P_3 = 280[/tex]

[tex]0.02(8000 - 3P_2) + 0.04P_2 + 0.05(2P_2) = 280[/tex]

[tex]0.08P_2 = 120[/tex]

[tex]P_2 = \frac{120}{0.08}[/tex]

[tex]P_2 = 1500[/tex]

Hence the other investments are given as follows:

Paper: 8000 - 3 x 1500 = $3,500.Glass: 2 x 1500 = $3,000.

a) As per the given percentage, the number of registered voters in the town who cast the votes are 155,952.

b) Reese claim is incorrect. The number he mentioned as registered voters is greater than the actual number of registered voters..

Percentage:

A percentage is a number or ratio which can be expressed as a fraction of 100.

For example, 57% can be written as 57/100.

Given,

The register voters and other in the town cast their vote on the election day.

a. In that particular town, 273,600 votes were cast in an election. And there are 57% of those who were registered voted.

Here we need to find how many registered voters are there in the town.

b. Reese claims that there are 60% of the registered voters cast 273,600 votes, there would be fewer registered voters than above.

Now we have also need to find whether his statement is correct or not with the reason.

Let x be the total number of registered voter who cast the vote.

From the given details, we know that, there are 273,600 voters are cast.

And 57% of them are registered voters.

So, it can be calculated as follows,

=> x  = 273600 of 57%

=> x = 273600 x 57%

=> x = 273600 x 57/100

=> x = 2736 x 57

=> x = 155, 952

Therefore, there are 155,952 registered voter in the town who cast the vote.

Based on these calculation we know that, Reese claims is incorrect because there the number of registered voters is 155, 952 which is not equal to the number he mentioned.

A car with an initial speed of 36 km/h accelerates at a uniform rate of 2.4 m/s^2 for 2.5 seconds. What are the final speed and displacement of the car during this time?

Answers

If a car with an initial speed of 36 km/h accelerates at a uniform rate of 2.4 m/s^2 for 2.5 seconds. The final speed is 16m/s and displacement of the car during this time is 32.5m.

Speed and displacement

23.7 km/h = 10 m/s

Using this formula to find the speed  vf = vi + a(Dt) for the final speed

Where:

Initial speed = 10 m/s

Acceleration = 2.4 m/s2

Time = 2.5 s

Let plug in the formula

vf = (10 m/s) + (2.4 m/s2)(2.5 s)

vf = 16m/s  fast car

Now, let's find or determine  the displacement

Using this  formula  Dx = vi(Dt) + 1/2a(Dt)2

Let plug in the formula

Dx = (10 m/s)(2.5 s) + 1/2(2.4 m/s2)(2.5 s)²

Dx = 32.5 m

Therefore we can conclude that the speed is 16m/s and the displacement is  32.5 m.

Answers

with the ticket price at $11 the average attendance has been 28000. when the price dropped to $10, the average attendance rose to 34000. Then the equation is y= -6000x+94000

We need to write expression of the attendance in terms of the price of the tickets.  We can determine the percentage increase of the attendance by decreasing the tickets price. We can have two points:

(11,28000) and (10,34000)

We have calculate the slope:

m= ( 34000 - 28000)/ (10-11)

m= - 6000

Substitute point into:

y= mx  +c

28000= -6000*11+c

28000+66000=c

94000=c

The equation is:

y= -6000x+94000

where x is the ticket price and y is the attendance.

Answers

The probability that none of the solar panels are defective is 0.97.

What is probability?The probability is the likelihood that something will happen, to put it simply. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.The study of events that fit into a probability distribution is known as statistics.The foundation for the modern mathematical theory of probability was built by Gerolamo Cardano, Pierre de Fermat, and Blaise Pascal in their analysis of games of chance in the sixteenth and seventeenth centuries, respectively.

So, the faulty solar panel percentage, p = 1/200 = 0.005.

q = 1 - p = 1 - 0.005 q = 0.995 is the percentage of solar panels that are in good condition.

Sample size, n = 6 likelihood that there are no damaged solar panels:

P(X=0)P = 0.97

So, the probability: 0.97

Therefore, the probability that none of the solar panels are defective is 0.97.

The quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.

According to the question,

We have the following information:

0.03 is divided by 0.148

And it can be simply expressed as 0.03/0.148

Now, we have the quotient as:

0.2027

Now, when rounding off the numbers we know that the digits from where we are rounding off we look at the right next to that digit and when that digit is greater than 5 then the digit should be increased by 1 and when that digit is less than 5 then the digit should be the same.

So, we will round it off by taking the underlined digit to be next to first 2:

So, the digit is 0.

Butt if we are taking the underlined digit as 2 to be the next 2 then the digit next to it is 7 which is greater than 5.

whats the gcf and distributive property of 15+36​

Answers

The gcf of 15 and 36 is 3 and   15 + 36 by distributive property is 51.

What is gcf?

The gcf(greatest common factor) is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

What is distributive property?

According to the distributive property, multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together.                         A (B + C) = AB + AC.

Given that, 15 and 36

Factor of 15 = 3 × 5

Factor of 36 = 2 × 2 × 3 × 3

gcf of 15 and 35 is 3 because 3 only one 3 is common in both the number.

Applying distributive property on 15 an 35 = 15 + 36

                                                                      = 3×5 + 3×12

                                                                      = 3(5 + 12)

                                                                      = 3(17) = 51

Therefore, the gcf of 15 and 36 is 3 and   15 + 36 by distributive property is 51.

Show that the two triangles are congruent. PLs help

Answers

Ignore the angles of triangle DEF. They complicate things when they don't need to be like that.

The distance from E to F is 3 units since there are 3 spaces between the points. Or you could subtract the x coordinates of each point, so 7-4 = 3.

So far we have one pair of congruent sides

EF = BC = 3

----------------------

Let's use the distance formula to find the distance from D to E

[tex]D = (x_1,y_1) = (3,-1) \text{ and } E = (x_2, y_2) = (7,-4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-7)^2 + (-1-(-4))^2}\\\\d = \sqrt{(3-7)^2 + (-1+4)^2}\\\\d = \sqrt{(-4)^2 + (3)^2}\\\\d = \sqrt{16 + 9}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]

Segment DE is exactly 5 units long.

We have another pair of congruent sides between the two triangles

AB = DE = 5

----------------------

We'll use the distance formula one last time to find the length of side FD.

[tex]D = (x_1,y_1) = (3,-1) \text{ and } F = (x_2, y_2) = (4,-4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-4)^2 + (-1-(-4))^2}\\\\d = \sqrt{(3-4)^2 + (-1+4)^2}\\\\d = \sqrt{(-1)^2 + (3)^2}\\\\d = \sqrt{1 + 9}\\\\d = \sqrt{10}\\\\\sqrt{10} \approx 3.162278 \approx 3.2\\\\[/tex]

Side FD is approximately 3.2 units long, which matches with AC = 3.2

--------------------

Here are the three paired sides that are congruent to one another

AB = DE = 5BC = EF = 3AC = FD = 3.2 approximately

Since we have three pairs of congruent sides, we can use the SSS (side side side) congruence theorem to prove the triangles are congruent.

Congruent triangles are identical copies or clones of one another. One triangle is just a reflected and translated version of the other.

This means they have the same corresponding angle measures, and the same corresponding side lengths.

Is 7 a factor of 49t + 30?

Answers

Number 7 is not a factor of the number 49t + 30.

What is defined as the factor?

A factor is a number which divides another number by itself and leaves no remainder.

In other sayings, if multiplying 2 whole numbers yields a product, the numbers being multiplied are factors of a product because of product is divisible by them.

Every integer has a limited number of factors.The factor of a number is often less than or equal to that number; it can never be greater than the number.With the exception of 0 and 1, each integer has at least two factors: 1 as well as the number itself.Division and multiplication are used to find factors.

For the given problem,

The equation is given as 49t + 30

For any value of t the number (49t will get completely divide by 7  leaving no remainder behind).

But 30 is not the factor of 7 as it will leave the remainder 2.

Thus, adding number 30 with 49t will result in a number which is not completely divisible by 7.

Thus, 7 is not a factor of number 49t + 30.
