Find the simple interest.
Principal:$6000
Interest Rates: 5%
Time: 6 months

Is it $1500 or $150?

Answers

Answer:

Given,

P = ₹5,000

R = 5%

T = 6 months

= 1/2 years

S.I = P×R×T/100

= 5,000 × 5 / 2×100

= 250 / 2

= ₹125

Step-by-step explanation:

The simple interest of principal of $ 6000 at an interest rate of 5% for a period of 6 months is $ 150

What is Simple Interest?

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the total amount be Principal P = $ 6000

Let the interest rate be R = 5 %

Let the number of periods be T = 6 months

So , the value of T = 1/2

Now , the simple interest is given by the formula

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

Simple Interest = ( 6000 x 5 x ( 1 / 2 ) ) / 100

Simple Interest = ( 60 x 5 ) / 2

Simple Interest = $ 150

Therefore , the value of simple interest is $ 150

Hence , The simple interest of principal of $ 6000 at an interest rate of 5% for a period of 6 months is $ 150

Step-by-step explanation:

If x = 3 (y + 2) minus 1 what is the value of w in terms of x and y? w = StartFraction x minus 3 y Over 3 EndFraction w = StartFraction x minus 3 y + 1 Over 3 EndFraction w = x minus 3 y + 1 w = StartFraction x + 1 Over 9 y EndFraction

Answers

Answer:

B.

Step-by-step explanation:

To find the value of w in terms of x and y, we need to substitute the given values of x and y into the equation for w. First, we are given the equation [tex]x = 3(y + 2) - 1[/tex].

Let's simplify this equation before substituting it into the equation for w. Expanding the equation, we have: [tex]x = 3y + 6 - 1 x = 3y + 5[/tex] Now we can substitute the value of x into the equation for w. w [tex]= (x - 3y + 1) / 3[/tex] Substituting the value of x from the earlier equation: w [tex]= (3y + 5 - 3y + 1) / 3 w = (6y + 6) / 3[/tex]

At this point, we can further simplify the equation by dividing both the numerator and denominator by 3: w[tex]= 2y + 2[/tex]Therefore, the value of w in terms of x and y is w[tex]= 2y + 2. I[/tex]n summary: Starting with x [tex]= 3(y + 2) - 1,[/tex]we substituted the value of x into the equation for w and simplified to obtain w [tex]= 2y + 2.[/tex]

Step-by-step explanation:

Step 1: Define Systems

1/2y = 4

x - 1/2y = 2

Step 2: Solve for y

Define equation:                    1/2y = 4Isolate y:                                 y = 8

Step 3: Solve for x

Define equation:                    x - 1/2y = 2Substitute in y:                       x - 1/2(8) = 2Multiply:                                  x - 4 = 2Isolate x:                                 x = 6

Answer: (6,8)

Step-by-step explanation:

1/2y = 4          

x - 1/2y = 2    

First  solve for y in the first equation.

1/2y = 4      Divide both sides by 1/2

y  =  8  

NOw substitute the value of y into the second equation and solve for x.

x

x - 1/2(8) = 2

x - 4 = 2

Answer:

Fill in the blank with 14

Step-by-step explanation:

Given

The attached table

Required

Fill in the gap

Since, the table represents a linear function.

The first step is to calculate the slope of the table

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (1,2)[/tex]

[tex](x_2,y_2) = (2,6)[/tex]

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{6 - 2}{2 - 1}[/tex]

[tex]m = \frac{4}{1}[/tex]

[tex]m=4[/tex]

The equation of the table is calculated next as:

[tex]y - y_1 = m(x - x_1)[/tex]

This becomes

[tex]y - 2 = 4(x - 1)[/tex]

[tex]y - 2 = 4x - 4[/tex]

Solve for y

[tex]y = 4x - 4+2[/tex]

[tex]y = 4x -2[/tex]

To fill in the blank;

The value of x is 4

So, substitute 4 for x in [tex]y = 4x -2[/tex]

[tex]y = 4 * 4 - 2[/tex]

[tex]y = 16 - 2[/tex]

[tex]y = 14[/tex]

katie collets stamp she has stamps from canada, United Staes,ands Rest of the world in a ratio of 1:1.2:1.5 she has 135 stamps from rest of the world

Answers

Answer:

90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World

Step-by-step explanation:

Since this is a problem of proportion we can use the Rule of three to solve this. We do this by multiplying the diagonal available values and dividing by the third value in order to get the missing variable, which in this case would be the number of stamps in the other country. Like so...

1.5  <=====>  135 stamps

1.2  <=====>  x  stamps (United States)

(1.2 * 135) / 1.5 = 108 stamps (United States)

1.5  <=====>  135 stamps

1  <=====>  x  stamps (Canada)

(1 * 135) / 1.5 = 90 stamps (Canada)

Finally, we can see that Katie had 90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World. All creating a ratio or 1:1.2:1.5

Answer:

Step-by-step explanation:

jane and her friends are diving to explore a wreckage from a ship that is 40 meters below sea level the platform they dive from is 10 meters above sea level.

Below sea level means = -40 m

Above sea level means = +10 m

It means,

-40 m + 10 m

= -30 m

Hence, they have to go 30 m below sea level to reach wreckage.

An advanced biology student wants to test the effects of a chemical fertilizer versus natural fertilizer, so she plans to divide a rectangular garden in half by running a fence parallel to two of the exterior sides. She has a fixed amount of fencing (36m) and she wants to have fencing around the entire garden in addition to the fence down the middle. Find the maximum area of the natural fertilizer garden.

Answers

Answer:

[tex]108\ \text{m}^2[/tex]

Step-by-step explanation:

The sides are rectangle is shown in the diagram

The perimeter of the fence will be

[tex]3x+2y=36\\\Rightarrow x=\dfrac{36-2y}{3}[/tex]

Area of the smaller section of the garden

[tex]A=xy\\\Rightarrow A=\dfrac{36-2y}{3}y\\\Rightarrow A=\dfrac{36y-2y^2}{3}[/tex]

Differentiating with respect to y we get

[tex]\dfrac{dA}{dy}=\dfrac{1}{3}(36-4y)[/tex]

Equating with zero we get

[tex]\dfrac{1}{3}(36-4y)=0\\\Rightarrow 36-4y=0\\\Rightarrow y=\dfrac{36}{4}\\\Rightarrow y=9[/tex]

Double derivative of area

[tex]\dfrac{d^2A}{dy^2}=-4<0[/tex]

at y = 9 the area is maximum

[tex]x=\dfrac{36-2y}{3}=\dfrac{36-2\times 9}{3}\\\Rightarrow x=6[/tex]

The sides of the entire garden are [tex]2y=2\times 9=18\ \text{m}[/tex] and [tex]6\ \text{m}[/tex]

The maximum area of the natural fertilizer garden is [tex]18\times 6=108\ \text{m}^2[/tex]

Answers

Answer:

Step-by-step expla

To find the volume of a cone, use the equation: V = 1/3Bh.

In this equation, V is the volume, B is the base, and h is the height.

We are given that the base is 12 inches, and the height is 18 inches. With those necessary values, we can substitute those values, and calculate it.

V = 1/3(12)(18)

V = 4(18)

V = 72.0

Therefore, the volume of this glass is 72.0 cubic inches.

y = 13 - 2x

2x + y = 14
x = 13-2y
2x + y = 17
-6x = 3y - 51
Reset
Next

Answers

Answer:

2x + y = 17

-6x = 3y - 51

Step-by-step explanation:

You get an infinite number of solutions when two equations are really just the same. This means you can convert one into the other simply by multiplying one to get the other.

In the above answer, if you multiply the above by -3 you get:

-6x -3y = -51

which is of course -6x = 3y - 51

So that is an example of a pair that has infinite solutions.

To find all of them, you'd carefully have to compare each 2 and see if there is a multiplier to convert one into the other. You can do that!
