which of the sentence is true?

Step-by-step explanation:

The graph is shown in the image above.

Answer: Draw a line through the two points (5,-3) and (7,-4)

See the diagram below.

=======================================================

Explanation:

Start at (5,-3). Then move down 1 and to the right 2 units to arrive at (7,-4)

The motion of "down 1, right 2" is from the slope of -1/2

slope = rise/run = -1/2

rise = -1 = go down 1 unit

run = 2 = go 2 units to the right

Two points are the minimum amount needed to draw any line. Plot the two points (5,-3) and (7,-4) and draw a straight line through them as shown in the diagram below. I used GeoGebra to make the graph. Desmos is another tool you could use.

Given vertices of the parallelogram:

Therefore the parallel sides are:

[tex]\sf \overline{HJ} \parallel \overline{LK}\:\: \textsf{ and }\:\: \overline{LK} \parallel \overline{HL}[/tex]

Therefore, the diagonals of the parallelogram are:

[tex]\sf \overline{LJ} \:\: \textsf{ and }\:\:\overline{HK}[/tex]

To find the coordinates of the intersection of the diagonals, either:

Midpoint between two points

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]

To find the midpoint of diagonal LJ, define the endpoints:

Substitute the defined endpoints into the formula and solve:

[tex]\begin{aligned} \implies \textsf{Midpoint of LJ} & =\left(\dfrac{3-1}{2},\dfrac{3-1}{2}\right)\\ & =\left(\dfrac{2}{2},\dfrac{2}{2}\right)\\ & =\left(1,1\right) \end{aligned}[/tex]

Therefore, the coordinates off the intersection of the diagonals of parallelogram HJKL are (1, 1).

Check the order

Means H,J and K,L are adjacent coordinates

Hence HK and JL are diagonals

We know diagonals of a parallelogram bisect each other so midpoint of any diagonal would be the intersection point

(i) Monthly installment is $21.53 approximately.

(ii) Total amount man has to pay is $3716.8

(iii) Extra money he had to pay for buying the computer on hire is $516.8

Given,

Initial price of the computer(p) = $3200

Down payment = $480

Time period = 2 yrs

rate percent = 9.5%

(i) Monthly installment = ?

monthly installment =(capital amount × interest rate)/time in months

down payment to be paid = 3200 ₋ 480

                                         = 2720

therefore, monthly payment = 2720 × 9.5 × 1/ 12

                                            = $21.53

(ii) Total amount man has to pay = ?

                                           = down payment ₊ remaining amount ₊                                                                                                                                                 (remaining amount × t × r)                                          

                                           = 480 ₊ 2720 ₊ 2720 × 9.5 × 2

                                           = $3716.8

(iii) If he buys the computer on hire then how much more he has to pay = ?

= total amount ₋ initial cost

= 3716.8 ₋ 3200

= $516.8

Hence the man has to pay $21.23 as a monthly installment, $3716.8 as a total cost of the computer system and $516.8 as an extra amount if he buys it on hire.

Answer:

[tex]\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given information:

We can assume that 3 pupils play the flute only as we have also been told that 6 pupils play both instruments.

To calculate the probability that a randomly chosen pupil plays neither instrument, first determine how many pupils do not play an instrument by subtracting the number of pupils who do play an instrument from the total number of pupils:

⇒ total number of pupils - pupils who play instruments

⇒ 20 - (3 + 6 + 6)

⇒ 20 - 15

⇒ 5

Therefore, 5 pupils do not play the piano and/or flute.

To calculate probability:

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

Therefore:

[tex]\implies \textsf{Probability of a pupil playing neither instrument} = \dfrac{5}{20}=\dfrac{1}{4}[/tex]

The correct answer from the task content is; Choice C; None of the above.

The equations can be evaluated as follows;

A) -x + (-x) =0

-x -x = -2x......Not True

B) x -(-x) = 0

x + x = 2x .....Not True.

On this note, it follows that none of the equations is true.

Answer:

$5.88

Step-by-step explanation:

3 erasers ⇒ $4,41

4 erasers ⇒ $A

A = 4 erasers * $4.41 / 3 erasers

A = $ 5.88

Answer:

see below

Step-by-step explanation:

Proportion:

4.41 is to 3 erasers as   'x' is to 4 erasers:

4.41 /3     =  x / 4       <======this is your proportion

 or rearrange

      4 *  4.41/3   = x  

(this results in x = $ 5.88  for 4 erasers )

Answer:

[tex]1875m^{3}[/tex]

Step-by-step explanation:

To find [tex]\frac{3}{4}[/tex] of the volume, we first must know the total volume.

The formula to find volume:

[tex]volume = length * width * depth[/tex]

We know the length is 25m, we know the width is 20m and we know the depth is 5m.

So, we can substitute them into the equation:

[tex]volume=25*20*5=2500m^{3}[/tex]

Now we know the total volume, we can find out the volume when it is [tex]\frac{3}{4}[/tex] full:

[tex]\frac{3}{4} * 2500 = 1875m^3[/tex]

Therefore, our final answer is [tex]1875m^{3}[/tex].
