Answers

The money borrowed by Alonzo at a simple interest rate of 8% for a time period of 2 years is $7000.

What is simple interest?

In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed). It is not the same as a fee that the borrower might pay to the lender or another entity.

Borrowers must pay lenders simple interest as a fee in exchange for a loan. For simple interest calculation, compounding interest is excluded from the calculation and just the original principal is used. Simple interest applies to all loans, not just specific ones. Additionally, it refers to the kind of interest that banks give their customers on their savings accounts.

Given,

 Time period = 2 years

Rate of interest = 8%

The simple interest paid at the end of 2 years = $ 1120

The money borrowed or the principal amount is

Simple interest = (Principal amount *  rate * time)

1120                  = P * 0.08 * 2

P = 1120/0.16 = $7000

Therefore the money borrowed by Alonzo at a simple interest rate of 8% for a time period of 2 years is $7000.

If the prism is surrounded by a fluid, what is the maximum index of refraction of the fluid that will still cause total internal reflection within the prism?.

Answers

The maximum index of refraction of the fluid that will still cause total internal reflection within the prism is nf = n/sinΘc.

Total internal reflection is a phenomenon in which light passes through a medium with a higher index of refraction and bounces back into the same medium instead of exiting it. This is possible when the angle of incidence is greater than the critical angle of the material.

In the case of a prism surrounded by a fluid, the maximum index of refraction of the fluid that will still cause total internal reflection within the prism can be calculated using Snell's law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the indices of refraction of the two materials.

The critical angle of the prism can be calculated as the angle at which the sine of the angle of refraction becomes equal to 1. The critical angle can be calculated using the equation:

sinΘc = 1/n

where n is the index of refraction of the prism.

The maximum index of refraction of the fluid can then be found by rearranging Snell's law and substituting the critical angle into the equation:

nf = n/sinΘc

Do the equations 1/5 + 2= 6 and 1/5(x +2)= 6 represent the same situation? Explain

Answers

No, the equations 1/5 + 2 = 6 and 1/5(x + 2) = 6 do not represent the same situation.

About the equationThe first equation, 1/5 + 2 = 6, is a simple arithmetic equation that can be solved to find the value of the variable. The second equation, 1/5(x + 2) = 6, is an algebraic equation that can be solved to find the value of the variable x.

To solve the first equation, we can subtract 2 from both sides to get 1/5 = 4, and then multiply both sides by 5 to get 1 = 20.

This equation is not true, so there is no solution. To solve the second equation, we can multiply both sides by 5 to get x + 2 = 30, and then subtract 2 from both sides to get x = 28.

which terms are used to describe events that have no outcomes in​ common?

Answers

The term used to describe events that have no outcomes in common is called "Mutually Exclusive."

Probability is a measure of how likely an event is to occur. The probability of an event ranges from 0 to 1, where 0 means that an event will not occur, and 1 means that an event will certainly occur.

In Mutually Exclusive events, the probability of both events happening at the same time is 0, which means that the outcome of one event completely eliminates the possibility of the outcome of the other event. The probability of getting heads and tails at the same time is 0, as it is impossible for the coin to show both heads and tails at the same time.

In mathematical terms, Mutually Exclusive events are represented by

=> P(A) + P(B) = P(A or B),

where P(A) represents the probability of event A, P(B) represents the probability of event B, and P(A or B) represents the probability of either event A or B occurring.

To summarize, Mutually Exclusive events are events that have no outcomes in common and have a probability of 0 of occurring simultaneously.

The base of s is the triangular region with vertices (0, 0), (8, 0), and (0, 4). Cross-sections perpendicular to the y-axis are equilateral triangles.

Answers

The volume of the triangular solid is 128/3 cubic units.

The cross-sections of the triangular solid along the y-axis are equilateral triangles with side length equal to the width of the triangular base at that y-coordinate. The width of the triangular base at y = h is equal to 8 - 4h/4. So, the side length of the equilateral triangle at y = h is 8 - 4h/4.

Let's call the height of the equilateral triangle at y = h as "x". Then, using the Pythagorean theorem, we can find the relationship between x and the side length:

x^2 = (8 - 4h/4)^2 - (x/2)^2

Expanding and simplifying the right-hand side:

x^2 = 64 - 16h + h^2/16 - x^2/4

Multiplying both sides by 4:

4x^2 = 256 - 64h + h^2 - x^2

Solving for x^2:

3x^2 = 256 - 64h + h^2

Taking the square root of both sides:

x = √(256 - 64h + h^2)/√3

So, the height of the equilateral triangle at y = h is equal to x = √(256 - 64h + h^2)/√3.

The volume of the triangular solid can be found by integrating the cross-sectional area over the height of the triangular base:

V = (1/3) ∫[0, 4] x^2(y) dy

= (1/3) ∫[0, 4] (√(256 - 64h + h^2)/√3)^2 dh

= (1/3) ∫[0, 4] (256 - 64h + h^2)/3 dh

Evaluating the definite integral:

V = (1/3) * [(256h/3 - 32h^2/2 + h^3/3) |_0^4]

= (1/3) * [(256/3 * 4 - 32/2 * 4^2 + 4^3/3) - (256/3 * 0 - 32/2 * 0^2 + 0^3/3)]

= (1/3) * (256 - 128 + 64/3)

B. 5/12

Answer: B

Step-by-step explanation:

Here's how to subtract 3/12 from 4/6:

4/6−3/12

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 4 by 12, and get 48.

Then we multiply 3 by 6, and get 18.

Next we give both terms new denominators -- 6 × 12 = 72.

So now our fractions look like this:

48/72−18/72

Step 2

Since our denominators match, we can subtract the numerators.

48 − 18 = 30

So the answer is:

30/72

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

30/72÷ 2 =15/36

Let's try dividing by 2 again...

Nope! So now we try the next greatest prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

15/36÷ 3 =5/12

Let's try dividing by 3 again...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

No good. 7 is larger than 5. So we're done reducing.

There you have it! The final answer is:4.6−3/12=5/12

What is Compound Interest?

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

(a) The final amount in a compound interest is,

A = P(1 + [tex]\frac{r}{n}[/tex] )^ (nt), where,

A : Final amount

P : Principal amount

r : Rate of interest

t : Time in years

n : number of times compounded in a year

Given A = $1500, P = $1000, r = 0.05, n = 1

The equation is,

1500 = 1000 (1 + 0.05)^t

(b) 1500 = 1000 (1 + 0.05)^t

1500 / 1000 = (1.05)^t

1.5 = (1.05)^t

Taking logarithm on both sides,

㏒ (1.5) = t ㏒ (1.05)         [since ㏒ (a)ᵇ = b ㏒ (a)]

solve for x 3x-6 x-2

Answers

Answer:

x=46

Step-by-step explanation:

this is how you set up the problem

3x-6+x-2=180

then you combine like terms

4x-6-6=180

then combine like terms again

4x-4=180

then you have to get 4 to the other side

4x-4=180

+4 +4

which leaves you with 4x=184

which you then divide both sides by 4

which leaves you with

x=46

I hope this helps you!!!

Graph the angle -4pi/3 in standard position

Answers

The angle -4π/3 in its standard position is added as an attachment

How to plot the angle in its standard position

From the question, we have the following parameters that can be used in our computation:

Angle = -4π/3

The coordinates of this point can be found by using the formula for converting from polar to rectangular coordinates:

x = cos(-4π/3)

y = sin(-4π/3)

So, we have

x = -0.5

y = 0.86

As an ordered pair, we have

(0.86, -0.5)

This means that we plot (0.86, -0.5)

The residents of a city voted on whether to raise property taxes. the ratio of yes votes to no votes was 5to 6. if there were 10,604total votes, how many yes votes were there?

Answers

The number of yes votes would be 4,836.

Solution:

Given,

The ratio of yes votes to no votes is 5:6. So, assuming the actual values of yes votes and no votes be 5x and 6x respectively. We can frame an equation as follows,

5x + 6x = 10,640

=> 11x = 10,640

=> x = 967.27272727

So, the number of yes votes would come out to be,

5*967.272727 = 4836.3636

Since the answer can not be a fractional integer,

therefore, we will round it up to 4,836.

Sam drive 965 mile from city A to city b ,Rita drive 1,041 mile from city C To city B

Answers

Sam travels on the highway for approximately 1.4 hours.

We know that Sam's total travel time is 1.5 hours plus the time he spends on the highway, which we'll call "x" hours. So his total travel time can be represented as:

Total travel time = 1.5 + x

We also know that the total distance he travels is 140 miles. We can use the formula:

distance = rate x time

to set up two equations, one for his travel on city roads and one for his travel on the highway. Let's start with the city roads:

distance = rate x time

distance = 35 mph x 1.5 hours

distance = 52.5 miles

So Sam travels 52.5 miles on city roads, which means he still has to travel:

140 miles - 52.5 miles = 87.5 miles

on the highway. Now we can set up an equation for his travel on the highway:

distance = rate x time

87.5 miles = 65 mph x x hours

Solving for x, we get:

x = 87.5 miles / (65 mph)

x ≈ 1.35 hours
