Step-by-step explanation:

check the pic. I just sent

the answer is $1500

The originally invested price will be;

⇒ $1,500

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Money is invested in a saving account at 12% simple interest.

And, After  one year there is $1680 in the account.

Now,

Let the original invested amount = x

So, We can formulate;

⇒ x + 12% of x = 1680

⇒ x + 12x/100 = 1680

⇒ 112x = 1680 × 100

⇒ 112x = 1,68,000

⇒ x = 1,68,000/112

⇒ x = $1,500

Thus, The original invested amount = $1,500

Answer:

5 inches tall i think

Step-by-step explanation:

sorry if its wrong

It's physics, right?

A. will have box 2.

B. will have box 1

C. will have box 3

Answer:

Part A will be the 2nd line

Part B will be the 1st line

Part C will be the 5th line

*note* I don't know if these lines move as you move them so I getting these answers as if they do not move.

Step-by-step explanation:

Let's start with part A.

It says he rides quickly. This means that as the distance increases, the time will increase slower.

So we are looking for a steep line. The steepest lines are line 2, 3 and 4

We know it can not be the 4th line because these line shows that time is no longer moving, just the distance.

Since it is impossible to freeze time, line 4 does not make any sense. So let's look at line 2 and 3

This can be confusing because it says down hill. So you may think it is line 3. When Cole goes down the hill, he is getting further from home. This means the line has to go up.

So that means part A has to be line 2.

Now let's start with part B

When graphing distance and time, if someone stops, their line stops moving in one direction too.

If you stop moving, you are not gaining any distance but time still moves.

This means we are looking for a line that moves in only 1 direction. These lines are lines 1 and 4.

On line 1, only time is moving

On line 4, only distance is moving

So like I said before, it is impossible to move while time is not moving. So line 4 makes no sense again. Leaving us with line 1.

So part B is line 1

Now we will do part C

It says that Cole rides slowly.

This means the line will not be steep. He is also still moving so it can not be line 1.

So we have line 5 and 6.

Since he is still moving away from the house, the line has to go up in distance and time. So this eliminates line 6

This leaves us with line 5

So the answer to part C is line 5

Hope this helps and have a great day!

Answer:

3

Step-by-step explanation:

First, we can start by multiplying the equation 2x - 3y = 12 by six to see where that gets us,

2x - 3y = 12 --> 12x - 18y = 72

12x - 18y = 72

5x + 6y = 18 (other equation)

We can notice that eliminating the y term would be the easiest to go about, so we want to find the number that we can multiply 6 by to get 18. That number is 3, so the factor is 3.

You can use the fact that non of 2 times 6 doesn't include 5 as factor.

There are two possible values of the factor by which if Yumiko multiplies the first equation and add the equations, a variable is eliminated.

Those values of the factor are [tex]3[/tex]   (for elimination of y) or [tex]-\dfrac{12}{5}[/tex] (for elimination of x)

Our aim in doing so is to make the coefficients of same variable equal and with opposite signs so that when we add the equations, that variable gets eliminated because of coefficient becoming zero.

For example, take the given equations and the factor by which Yumiko multiplied the second equation.

5x + 6y = 18

2x – 3y = 12 => 12x - 18y = 72   (since she multiplied this with 6)

Let she multiply the first equation with factor "p"

Then we will have the system as;

[tex]p \times 5x + p \times 6y = p \times 18\\12x - 18y = 72[/tex]

Adding both the equations, we get:

[tex](5p + 12)x + (6p - 18)y = 18p + 72[/tex]

Since there are two variables and since any one of them can be eliminated depending on the value of p, thus we have two cases:

Then we have coefficient of x = 0

or

[tex]5p + 12 = 0\\5p = -12\\p = -\dfrac{12}{5}\\[/tex]

Then we have coefficient of y = 0

or

[tex]6p - 18 = 0\\6p = 18\\p = \dfrac{18}{6} = 3[/tex]

Thus, there are two possible values of the factor by which if Yumiko multiplies the first equation and add the equations, a variable is eliminated.

Those values of the factor are [tex]3[/tex]  or [tex]-\dfrac{12}{5}[/tex]

Answer:

I agree with daniel

Step-by-step explanation:

Given the area of a rectangle expressed as;

A(x) = 2x²+10x+12

On factorizing;

A(x) = 2x²+6x+4x+12

A(x) = 2x(x+3)+4(x+3)

A(x) = (x+3)(2x+4)

since A(x) = l(x)w(x)

Hence the legnth and width of the rectangle are 2x+4 and x+3.

Also A(x) = 2x²+6x+4x+12 can be factorized as;

A(x) = 2x²+4x+6x+12

A(x) = 2x(x+2) + 6(x+2)

A(x) = 2x+6(x+2)

Therefore I agree with Daniel. The factor differs due to the difference in arrangement of 4x and 6x in the expression. Precedence of values affects the final factors

Step-by-step explanation:

The volume of a pyramid is given by the formula ...

  V = 1/3Bh

where B is the area of the base, and h is the height of the pyramid. Here, h=8 in.

__

Here, the base is a triangle. The formula for its area is ...

  A = 1/2bh

where b is the base segment of the triangle, and h is the height of the triangle perpendicular to the base segment. Here, b=10 in, and h = 6 in.

The triangular base area is ...

  A = 1/2(10 in)(6 in) = 30 in^2 . . . . base area "B"

__

Using the above base area and pyramid height, we find the volume of the pyramid is ...

  V = 1/3(30 in^2)(8 in) = 80 in^3

The volume of the pyramid is 80 cubic inches.

Answer:

y = 5/4 x + 9

y = -5x+4

Step-by-step explanation:

a)The equation of the line in slope intercept form is expressed as y = mx+b

m is the slope

b is the intercept

Given

Slope m = 5/4

y-intercpet = 9

Substitute

y = mx+b

y = 5/4 x + 9

b) Given the coordinates (0,4) and (2, -6)

Slope m = -6-4/2-0

m = -10/2

m = -5

Since the y intercept of the line is (0, 4), hence b = 4

Get the equation

Recall

y = mx+b

y = -5x +4

This gives the required equation

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

Mathematically, the mean is the sum of the numbers divided by the count of the numbers

The count of the numbers is 5

Thus;

( 4 + 8 + 9 + x + 2x)/5 = 6

(21 + 3x)/5 = 6

21 + 3x = 6(5)

21 + 3x = 30

3x = 30-21

3x = 9

x = 9/3

x = 3
