If the area of a pentagonal pyramid has a 440.4 mm² base area, 16 mm. pentagon side
length, and 20 mm. slant height, then determine the surface area of the pyramid.

Step-by-step explanation:

we know that

The surface area of a pentagonal pyramid is given by the formula

where

B is the area of the pentagonal base

LA is the area of  its five congruent lateral triangles

we have

so

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
