Answer:

2/7

Step-by-step explanation:

This is a very simple question worded very weirdly.

There are seven days in a week and only one Sunday in a week.

So the chance that one friend was born on the same week of the day is 1/7.

However, there are 2 friends and we are looking for the probability that at least one of these friends was also born on a Sunday, so we just add 1/7 + 1/7.

1/7 + 1/7 = 2/7, so the chance that at least one of the friends was also born on a Sunday is 2/7.

Elias has decided to fence in a garden that is in the shape of a parallelogram. If one side measures 76 ft and 250 ft of fencing
Leni [432]

The length of side of garden are 76 feet and 49 feet

<em><u>Solution:</u></em>

Given that, Elias has decided to fence in a garden that is in the shape of a parallelogram

Measure of one side = 76 feet

250 ft of fencing is needed to enclose the garden

Therefore, perimeter = 250

<em><u>The perimeter of parallelogram is given by:</u></em>

Perimeter = 2(a + b)

Where, a and b are the length of sides

Here, a = 76

b = ?

<em><u>Substituting in formula, we get</u></em>

250 = 2(76 + b)

250 = 152 + b

2b = 250 - 152

2b = 98

b = 49

Thus the length of side of garden is 49 feet
