Find the area of the regular trapezoid. The figure is not drawn to scale. The top side is 4, the bottom side is 7, and both side
svp [43]
A regular trapezoid is shown in the picture attached.

We know that:
DC = minor base = 4
AB = major base = 7
AD = BC = lateral sides or legs = 5

Since the two legs have the same length, the trapezoid is isosceles and we can calculate AH by the formula:

AH = (AB - DC) ÷ 2
      = (7 - 5) ÷ 2
      = 2 ÷ 2
      = 1

Now, we can apply the Pythagorean theorem in order to calculate DH:
DH = √(AD² - AH²) 
      = √(5² - 1²)
      = √(25 - 1)
      = √24
      = 2√6

Last, we have all the information needed in order to calculate the area by the formula:

A =  \frac{(AB + CD)DH}{2}

A = (7 + 5) × 2√6 ÷ 2
   = 12√6

The area of the regular trapezoid is 12√6 square units.

An experienced cashier at a grocery store takes 2 seconds to scan each item and 40 seconds to process the customer's payment. 1)
grigory [225]

Answer:

The correct option is D) 43 items.

Step-by-step explanation:

As we know that total given time is ,

Y = (60\times2) +6 =126\hspace{0.15cm} sec,

Out of which cashier spends 40 seconds to process the customer's payment.

So the remaining time = (126 - 40) = 86 secs.

And the remaining time is used to scan the item and so that we can calculate here the no items scan is = (86 ÷ 2) = 43.

Therefore we can say that 43 items are being purchased.

4/3+căn5 - 8/1+căn5 +15/căn5
padilas [110]

Answer:

A= \frac{4}{3 +  \sqrt{5} }  -  \frac{8}{1 +  \sqrt{5} }  +  \frac{15}{ \sqrt{5} }

=  \frac{4(3 -  \sqrt{5)} }{4}  -  \frac{8(1 -  \sqrt{5} }{ - 4}  +  \frac{15 \sqrt{5} }{5}  = 3 -  \sqrt{5 + 2 - 2 \sqrt{5 + 3 \sqrt{5 = 5} } }
