Answer:  $1487.50

Step-by-step explanation:

hey there again!

Facts:

Principal (starting amount): $1,400

Annual interest rate: 12.5% of the principal. Whenever you get an annual interest rate as a percentage, its always that percentage of the starting amount.

Time given: 6 months, 1/2 a year

the question asks "total amount due' in 6 months. Basically, we want to know how much they will have in their account after 6 months.

Step 1: Find how much interest he will get in 6 months as a percentage.

6 months is 1/2 of a year, so find 1/2 of 12.5

1/2 of 12.5

1/2 x 12.5

0.5 x 12.5

6.25%

Step 2: Find how much interest he gets, but as a number.

Principal: $1400

6.25% of 1400= $87.50

Step 3: Find the total amount of money he will have after 6 months.

he starts with 1400, and gets an additional $87.50 added to his account after 6 months. How much does he have now?

To answer this, add to find the total:

87.50+1400= $1487.50

Answer: 64$

Day one: 2

Day two: 2 x 2 = 4

Day three: 4 x 2 = 8

Day four: 8 x 2 = 16

Day five: 16 x 2 = 32

Day six: 32 x 2 = 64

Answer:

its 64 i believe. its the same thing as 2 to the 6th power. 2+2, 4+4, 8+8, 16+16, 32+32

either that or add 64 plus 64 to get 128 if 64 isnt correct

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

After giving buttons to his friends, James have left with 4000 buttons.

Given that James has 8000 buttons he distributed 4000 buttons to his friends, we need to find how much he have now,

If James originally has 8,000 buttons and he gives 4,000 buttons to three friends, we can calculate the number of buttons he has left by subtracting the buttons given away from the original number.

Buttons James has left = Original number of buttons - Buttons given away

Buttons James has left = 8,000 - 4,000

Buttons James has left = 4,000

Based on the calculations, it seems that James would have 4,000 buttons left.

Answer:

y=-4/3+3

Step-by-step explanation:

To find this equation in slope-intercept form you must first put it into point-slope form. Remember point-slope is \(y-y_{2}=m(x-x_{2})\) so plugin the points and slope to get \(y-7=-4/3(x+3)\). Then solve the equation for y.

First, distribute the -4/3

y-7= -4/3x-4

Then, add 7 to both sides

y=-4/3+3

Answer:

y=-4/3x+3

Step-by-step explanation:

y-7=-4/3(x-(-3))

y-7=-4/3x-4

y=-4/3x+3

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

Here is an example of how to draw an isosceles trapezoid:

   _______

 /                 \

/_________\

In this trapezoid, the two parallel sides (the top and bottom sides) are of equal length, and the two non-parallel sides (the left and right sides) are also of equal length. The angles between the top and left sides and between the top and right sides are equal, as are the angles between the bottom and left sides and between the bottom and right sides.

An isosceles trapezoid is a type of trapezoid where the two non-parallel sides of the trapezoid are of equal length. This means that the trapezoid has a line of symmetry through its mid-point, which divides the trapezoid into two congruent triangles. The two parallel sides of an isosceles trapezoid are also referred to as bases, and the height of the trapezoid is the perpendicular distance between the two bases.

Because an isosceles trapezoid has two congruent triangles, the angles opposite these sides are also congruent. Therefore, an isosceles trapezoid has two pairs of congruent angles, with each pair containing one acute angle and one obtuse angle. The acute angles are located adjacent to the parallel sides, while the obtuse angles are located adjacent to the non-parallel sides.

Isosceles trapezoids have several interesting properties, including that the diagonals of an isosceles trapezoid are congruent, and that the diagonals bisect each other. Additionally, the length of each diagonal can be found using the Pythagorean theorem, and the area of an isosceles trapezoid can be determined using the formula:

Area = ((a + b) / 2) * h

Where "a" and "b" are the lengths of the two parallel sides (bases) and "h" is the height of the trapezoid.

PART B:

An isosceles trapezoid is a quadrilateral with two parallel sides (the bases) and two non-parallel sides of equal length. A parallelogram is also a quadrilateral with two pairs of parallel sides.

An isosceles trapezoid can be thought of as a special case of a parallelogram where one pair of opposite sides is shorter than the other pair. In fact, if you extend the non-parallel sides of an isosceles trapezoid until they intersect, you will get a parallelogram with the same base and height as the original trapezoid.

Conversely, if you take a parallelogram and draw a line segment parallel to one pair of opposite sides, you will get an isosceles trapezoid. This means that every isosceles trapezoid can be thought of as a parallelogram with a missing piece, and every parallelogram can be thought of as an isosceles trapezoid with extra pieces added on.

So, in summary, isosceles trapezoids and parallelograms are related in that isosceles trapezoids can be thought of as special cases of parallelograms, and parallelograms can be thought of as isosceles trapezoids with extra pieces added on.

PART C:

No, we cannot use the term "isosceles" to describe a rectangle because a rectangle, by definition, has four right angles and opposite sides that are parallel and congruent to each other. An isosceles trapezoid, on the other hand, has only one pair of parallel sides and two non-parallel sides that are congruent to each other.

The term "isosceles" is typically used to describe triangles or trapezoids where two sides are congruent to each other. In an isosceles triangle, two sides are equal in length, while in an isosceles trapezoid, two non-parallel sides are equal in length. However, in a rectangle, all four sides are equal in length, not just two.

Therefore, while we can describe a rectangle as having all sides congruent to each other, we cannot describe it as an isosceles rectangle because "isosceles" implies only two sides are congruent, which is not the case for a rectangle.

Answer:

3x(2x -3)

Step-by-step explanation:

Simplifying the expression:

6x² - 9x

6x² = 2 * 3 * x * x

9x = 3 * 3 *x

Common factor = 3x

Take out the common factor from both the term.

6x² - 9x = (3x * 2x) - (3x * 3)

              = 3x * (2x - 3)

Answer:

it is the third one

Step-by-step explanation:

well, if you can go up down and sideways, I'd say, B, F, G, and D

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Answer:

Not necessarily. If picture is drawn to scale, no.

Step-by-step explanation:

Line segment EF is certainly perpendicular to line segment AC, but we don't know if it bisects or not.

If the picture isn't drawn to scale, there is no way to know if EF is a perpendicular bisector to AC or not because we do not know if AD = CD.

If the picture is drawn to scale, EF is not a perpendicular bisector to AC because we can see that AD ≠ CD and therefore EF cannot be a perpendicular bisector.
