WITCHER [35]

Answer: B

Step-by-step explanation:

S = An/1 - r

A1 = 6

6/1 - (-1/4)

6/1 + (1/4)

6/1.25

S = 4.8 or 24/5

One year, the population of a city was 330,000. Several years later it was

goblinko [34]

Answer:

18%

Step-by-step explanation:

Express the ending population as a percentage of the starting population:

270000 divided by 330000=0.82

0.82 *100=82

subtract from the 100% we started with to get the percent decrease:

100% - 82% = 18

Your sock drawer has six white socks, six brown socks, and four black socks. you randomly pick two socks and get a matching pair

Helen [10]

Total socks in the drawers = 6 + 6 + 4 = 16

Probability of picking the first black sock = 4/16
Probability of picking the second black sock = 3/15

Probability of picking two black socks = 4/16 × 3/15 = 1/20

A pyramid has a regular hexagonal base with side lengths of 4 and a slant height of 6. Find the total area of the pyramid.

Tanzania [10]

The total area of pyramid is 113.569 square units

The equation to find the total area of the pyramid is Total area = base area + lateral area.

Solution:

Given, A pyramid has a regular hexagonal base with side lengths of 4 and a slant height of 6.

The total area of pyramid is given by:

$A=A_{b}+A_{l}$ ---- eqn 1

Where,

$A_{b} \text { is the base area and } A_{l} \text { is the lateral area }$

The area of base is given as:

$A_{b}=\frac{3 \sqrt{3}}{2} l^{2}$

Where "l" is the side of hexagon.

Substituting we get,

$\begin{array}{l}{A_{b}=\frac{3 \sqrt{3}}{2}(4)^{2}} \\\\ {=\frac{3 \sqrt{3}}{2} \times 16=3 \sqrt{3} \times 8} \\\\ {A_{b}=24 \sqrt{3}}\end{array}$

The lateral area is given as:

$A_{l}=3 b h$

Where,

b: base of the triangle

h: height of the triangle

Substituting we get,

$\begin{array}{l}{A_{l}=3 \times(4) \times(6)} \\\\ {A_{l}=72}\end{array}$

Plugging in the values we found in eqn 1 we get,

$A=24 \sqrt{3}+72$

A = 113.569 square units

Summarizing the results:

The total area of pyramid is 113.569 square units approximately

The equation used to find total area of pyramid is Total area = base area + lateral area.
