Leno4ka [110]

Answer:

Option 4. Perimeter = 30 units

Step-by-step explanation:

Since the volume of a pentagonal prism is 840 cubic units.

Perpendicular distance between the bases = 14 units

We know volume of a pentagonal prism = Area of base × distance between the bases

840 = Area × 14

Area = 840/14 = 60 square units

Now area of a pentagon

A=\frac{a^{2}}{4}\times\sqrt{5(5+2\sqrt{5})}

1.72a^{2}=60

a^{2}=\frac{60}{1.72}=34.90

a=\sqrt{34.9}=5.91

Therefore perimeter of the pentagon = 5×a = 5×5.91 = 29.54 ≈ 30 units

horsena [70]

Answer: \dfrac{1}{4}

Step-by-step explanation:

Given : The number of children in a family is 1, 2, 3, or 4.

Little Joe (a boy) has no brothers. But he may have sisters.

The sample space for the number of child in Joe's family : {B, BG, BGG, BGGG}, where G represents girl and B represents boys.

Then , for the probability that he is an only child, favorable outcome = B

Thus, the probability that he is an only child is given by :-

=\dfrac{\text{Favorable outcome}}{\text{Total outcomes}}=\dfrac{1}{4}

Hence, the probability that he is an only child = \dfrac{1}{4}
