Answer:

d = 12 and n = 26

Step-by-step explanation:

Given that the fractions are equivalent then

[tex]\frac{2}{3}[/tex] = [tex]\frac{8}{d}[/tex] ( cross- multiply )

2d = 24 ( divide both sides by 2 )

d = 12

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

and

[tex]\frac{2}{3}[/tex] = [tex]\frac{n}{39}[/tex] ( cross- multiply )

3n = 78 ( divide both sides by 3 )

n = 26

The fractions represent the same amount or value given that they are

equivalent.

Reasons:

Equivalent fractions are fractions that have equal values, therefore;

[tex]\displaystyle \frac{2}{3} = \frac{8}{d} =\frac{n}{39}[/tex]

Which by cross multiplying gives;

2 × d = 8 × 3 = 24

Therefore;

[tex]\displaystyle d = \frac{24}{2} = \mathbf{12}[/tex]

d = 12

Similarly, we have;

[tex]\displaystyle \frac{2}{3} =\frac{n}{39}= \frac{8}{d}[/tex]

Which gives;

2 × 39 = 3 × n

Therefore;

[tex]\displaystyle n = \frac{2 \times 39}{3} = \mathbf{26}[/tex]

n = 26

Answer:

b. $1584.52

Step-by-step explanation:

To find the answer, first you have to find the amount that you will have after 9 years using the formula to calculate the future value:

F=P*(1+i)^n, where

F= future value

P= present value= $2874

i= interest rate= 5%

n= number of periods of time= 9

Now, you can replace the values in the formula:

F=2874*(1.05)^9

F= 4458.52

Then, as you know the value that you will have after 9 years, you can subtract the initial balance from this, to find the amount of interest:

$4,458.52-$2,874= $1,584.52

According to this, the answer is that the amount of interest at 5% compounded annually would be $1,584.52.

Answer:

[tex]d+0.5c+2r=8\\\\ c=2d[/tex]

Step-by-step explanation:

Let d= dramas

c= comedies

r= reality shows

Dramas are 1 hour long, comedies are 30  minutes, and reality shows are 2 hours long.

Total time spent on watching = [tex]1 \times(d) + 0.5 \times (c) +2 \times(r)= d+0.5c+2r[/tex]

 [  [tex]30\ minutes=\dfrac{30}{60} \ hours = 0.5 hour \ \ (1 hour = 60\ minutes)[/tex]  ]

Since he spent 8 hours for this, that means

[tex]d+0.5c+2r=8[/tex]     → First equation

He watches twice as many comedies as dramas.

i.e. [tex]c=2d[/tex] → second equation

So, the system of equations could be used to determine how many of each type of show he watches each week:

[tex]d+0.5c+2r=8\\\\ c=2d[/tex]

Answer : The area of the figure composed of a parallelogram, a square and a rectangle is 126 in².

Step-by-step explanation :

Area of composed figure = Area of parallelogram + Area of square + Area of rectangle

First we have to calculate the area of parallelogram.

Area of parallelogram = Base × Height

Given:

Base = 10 in

Height = 3.5 in

Area of parallelogram = 10 in × 3.5 in

Area of parallelogram = 35 in²

Now we have to calculate the area of square.

Area of square = (Side)²

Given:

Side = 4 in

Area of square = (4 in)²

Area of square = 16 in²

Now we have to calculate the area of rectangle.

Area of rectangle = Length × Breadth

Given:

Length = 12.5 in

Breadth = 6 in

Area of rectangle = 12.5 in × 6 in

Area of rectangle = 75 in²

Now we have to calculate the composed figure.

Area of composed figure = Area of parallelogram + Area of square + Area of rectangle

Area of composed figure = 35 in² + 16 in² + 75 in²

Area of composed figure = 126 in²

Therefore, the area of the figure composed of a parallelogram, a square and a rectangle is 126 in².

The area of the given figure is 126in²

The given figure is a composite figure composed of a parallelogram, a square and a rectangle.

Get the area of the square

Area = L²

Area of the square = 4² = 16in²

Area of the rectangle = 6 * 12.5

Area of the rectangle = 75in²

For the parallelogram:

Area of the parallelogram = Base * Height

Area of the parallelogram = 10 * 3.5

Area of the parallelogram  = 35 in²

Area of the figure = 75in² + 35in² + 16in²

Area of the figure = 126in²

Hence the area of the figure is 126in²

Kono divides The numerator and the denominator of 48 over 72 by the greatest common factor to simplify the fraction in one step by what number does he divide

Answer:

2/3

Step-by-step explanation:

Given the number : 48 / 72

Obtain the greatest common factor of 48 and 72

- - - - 48 - - - - 72

- 2-- 24 - - - - 36

- 2 - 12 - - - - - 18

- 2 - 6 - - - - - - 9

- 3 - 2 - - - - - - 3

The greatest common factor of 48 and 72 is hence (2 * 2 * 2 * 3) = 24

Hence, divide both the numerator and denominator by 24 ;

Numerator = 48/24 = 2

Denominator = 72 / 24 = 3

Step-by-step explanation:

|3x| > -12

There are two cases, x is either positive (in which |3x| = 3x) or negative (in which |3x| = -3x). Therefore:

3x > -12 or -3x > -12

x > -4 or x < 4 (Remember, multiplying / dividing an inequality by a negative number flips the sign.)

Answer:

All real numbers.

Step-by-step explanation:

So we have the equation:

[tex]|3x|>-12[/tex]

Remove the absolute value bars. Definition of absolute value:

[tex]3x>(-12)\text{ or } 3x<-(-12)[/tex]

Note that we change the sign on the right because we multiplied by a negative.

Divide both sides by 3:

[tex]x>-4\text{ or }x<4[/tex]

Now, look at this inequality. This says that the solution is all the numbers to the right of -4 and all numbers to the left of 4.

I've provided a number line. The red line represents x>-4 and the blue line represents x<4.

As you can see, every value is covered both towards the left and the right.

In other words, our answer is all real numbers.

Parallel lines are always coplanar. Perpendicular lines are always coplanar and, Distance around an unmarked circle can never be measured.

Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.

1. Parallel lines are always coplanar.

When two lines are parallel to each other it means that the two lines will never intersect each other and their plane is also the same.

2. Perpendicular lines are always coplanar.

From the definition that two lines will be perpendicular to each other their angle should be 90 degrees or they should intersect at 90 degrees angle to each other.

3. Distance around an unmarked circle can never be measured.

We need to have a marked circle to measure the distance. So, the distance from the centre of the circle to one point of it is the radius. Moreover, the distance between two points of the circle taking a line passing through the centre is the diameter of the circle.

Answer:

9 cm

Step-by-step explanation:

First, we need to find the volume of the cylindrical water bottle. The volume of a cylinder is πr²h where r = radius and h = height. In this case, r = diameter / 2 = 6.5 / 2 = 3.25 and h = 21 so the volume is π * 3.25² * 21 = 221.8125π ≈ 696.84. Let's call the length of the cubic container s. The volume of the cube (which is s³) must be at least the volume of the water bottle, therefore:

s³ ≥ 696.84

∛s³ ≥ ∛696.84

s ≥ 8.86566

The smallest integer value that satisfies this is 9 cm.

Answer:

14,100.03 (just finished a test with this question and got it correct)

The car is worth about $14,100.03 after the second year.

The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.

If a car depreciates at a rate of 24.9% annually, then its value at the end of each year is 75.1% of its value at the beginning of the year (100% - 24.9% = 75.1%).

After the first year, the car's value is:

$25,000 × 0.751 = $18,775.00

After the second year, the car's value is:

$18,775.00 × 0.751 = $14,100.03

Therefore, after the second year, the car is worth about $14,100.03.
