Answer:

Step-by-step explanation:

The diagonals of the parallelogram are AC and BD. The way the diagram is drawn, BD is the long diagonal, said to be 24 inches. AC is the short diagonal, said to be 12 inches.

Since AC bisects BD at point E, point E is the midpoint of BD. That means BE = (24 inches)/2 = 12 inches.

Since BD bisects AC at point E, point E is the midpoint of AC. That means EC = (12 inches)/2 = 6 inches.

Now, we know the lengths of the sides of ΔBEC, so we can find its perimeter. The perimeter of any geometry is the sum of the lengths of its sides.

perimeter ΔBEC = CB +BE +EC

perimeter ΔBEC = 10 in + 12 in + 6 in = 28 in

The perimeter of triangle BEC is 28 inches.

Negative sixteen plus the quotient of a number and -4 is -3

IRINA_888 [86]

The number you are in search of is -52.

To find this, we first have to write the equation that goes along with the sentence. For this, we need to take it one term at a time.

Negative sixteen (-16) plus (+) the quotient of a number and -4 (x/-4) is (=) -3.

Now put the parenthesis together

-16 + x/-4 = -3

Now we can solve this for x.

-16 + x/-4 = 3 ---> add 16 to both sides

x/-4 = 13 ----> multiply both sides by -4

x = -52

Answer:

Answers B and D.

Step-by-step explanation:

The center of the distribution for the leopards is around 50 kg while for the tigers it is around 130 kg, so as far a centers, the leopards have a lower median weight than the tigers (Answer B)

With regards to the spread, the leopards go from 30 to 70 kg, while the tigers go from 110 to 170 kg. Therefore, the tigers spread out more than the leopards (Answer D).
