A customer enrolled in a 1 year product purchase plan that cost $60 per month after 6 months the customer received a monthly dis

kolbaska11 [484]

Answer:

The total amount customer will pay for the 1 year plan is $ 648.

Step-by-step explanation:

Product Plan = $60 per month

⇒ Money he pay for 1 month = $ 60

Money He pay for first 6 month = 6 × 60 = $ 360

after 6 month he receives 20% discount monthly,

So, Now he pay for 1 month = 60 - 20% × 60 = $60-\frac{20}{100}\times60$

= 60 - 12 = $ 48

Money he pay for last 6 month = 6 × 48 = 288

Total Money he pay in a year = 360 + 288 = $ 648

Therefore, The total amount customer will pay for the 1 year plan is $ 648.

Find the coordinates of the intersection of the diagonals of parallelogram HJKL with the given vertices: H(-1, 4), J(3, 3), K(3,

lakkis [162]

Answer:

(1, 1)

Step-by-step explanation:

Given vertices of the parallelogram:

H = (-1, 4)
J = (3, 3)
K = (3, -2)
L = (-1, -1)

Therefore the parallel sides are:

$\sf \overline{HJ} \parallel \overline{LK}\:\: \textsf{ and }\:\: \overline{LK} \parallel \overline{HL}$

Therefore, the diagonals of the parallelogram are:

$\sf \overline{LJ} \:\: \textsf{ and }\:\:\overline{HK}$

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

draw a diagram (see attached) and determine the point of intersection of the diagonals from the diagram, or
determine the midpoint of either diagonal (as the diagonals of a parallelogram bisect each other, i.e. divide into 2 equal parts).

Midpoint between two points

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

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

$(x_1,y_1)=L=(-1, -1)$
$(x_2,y_2)=J=(3,3)$

Substitute the defined endpoints into the formula and solve:

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

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

Please I need help now

All you have to do in order to solve for the length of the square, simply take the expression and divide each term in the equation by 4, since the perimeter equation is the result of the length of the side equation multiplied by 4.

The final solution would be C.

Answer:

2.73 8.75

Step-by-step explanation:

n = 1

1 (DOUBLE) = 1+1 = 2

2 +3/4 = 1.5

1.5 +2 = 3.5

3.5 x 0.22 = 0.77

3.5 - 0.77 = 2.73

n = 1

1 + 3/4 = 1 + 0.75 = 1.75

1.75 (DOUBLE) = 3.5

3.5 x 2 1/2 = 8.75
