Answer: 8

The point E in the parallelogram is located at the crossing point of the diagonal line. It can be concluded that the distance of AE is equal to CE, or equal to 1/2 AC. Then you can get three equation like this:
AE=CE
<span>AE=x^2−8
CE=2x .

Using these equation you can find the value of x
AE= CE
</span>x^2−8 = 2x
x^2−2x-8 = 0
(x- 4)     (x+2)
x1= 4     x2= -2

Excluding the minus result, you can get that AE= CE= 4
Then AC would be: 
AC= AE+CE
AC= 4 + 4= 8

Can someone help me for this question?​
Taya2010 [7]

Answer:

2x + 1y =< 300

x + y =>150 units

y <= 2x

Step-by-step explanation:

Let x and y be the numbers of corndogs and shakes that will be sold.

<u>1.</u>  The total cost of making these items is given by the sum of:

(x)(RM2) + (y)(RM1)

A total of RM300 is allocated for the cost of these items, so:

2x + 1y =< 300   [Units are RM)

<u>2.</u> Sales are expected to exceed 150 units, in total.  This means:

x + y =>150 units

<u>3.</u>  Sales for the shakes is less than 2 times that of the corndogs:

y <= 2x

Find the coordinates of the points of intersection of the graph of y=13−x with the axes and compute the area of the right triang
Ymorist [56]

the coordinates of the points of intersection of the graph of y=13−x with the axes

Given equation is y=13-x

x axis is x=0

y axis is y=0

Plug in the value of x =0 and find out y

y = 13 - x

y = 13 - 0 = 13

Plug in the value of y=0 and find out x

0 = 13 - x

x= 13

So coordinate axis

x= (13,0)

y= (0,13)

Base of the triangle is x=13

Height of the triangle is y= 13

Area of the triangle = \frac{1}{2} * base * height

= \frac{1}{2} * 13 * 13 = 84.5

Area of the triangle = 84.5

A swimming pool holds 540,000 liters of water. The pool has two drain pipes. When the pool is completely full, the first pipe al
tankabanditka [31]

Answer: 72 minutes

Step-by-step explanation:

Pipe A can empty the water in 180 minutes = (180/60) =3 hours

Pipe A does 1/ 3 of the job in 1 hour.

Pipe B can empty the water in 120 minutes = (120/60) = 2 hours.

Pipe B does 1/ 2 of thejob in 1 hour.

Together they will do:

1/ 3 + 1/ 2 = 5/6

Together, both pipes will do 5/ 6 of the job in one hour.

To get the total time to completely drain the water will be:

= 60 ÷ 5/6

= 60 × 6/5

= 12 × 6

= 72 minutes

It takes 72 minutes to empty the pool.
