A regular triangular pyramid has a base area of 31.5 mm2 and a surface area of
Virty [35]

Answer:

A) 220.5 mm^2

Step-by-step explanation:

<u>Explanation</u>:-

Given A regular triangular pyramid has a base of area is 31.5mm^2

and also given surface area of triangular pyramid is 252 mm ^2

by using formula

surface area of  regular triangular pyramid = base of area + half of lateral surface.

surface area = area of the pyramid X \frac{1}{2} lateral surface

252 = 31.5 + \frac{1}{2} lateral surface

252-31.5= \frac{1}{2} lateral surface

220.5 = lateral area of triangular pyramid

lateral area of triangular pyramid = 220.5 mm^2

Formulate the situation as a system of inequalities. (Let x represent the number of goats the farmer can raise and y represent t
Firdavs [7]

Answer: He can raise up to 40 goats and 100 llamas.

Step-by-step explanation:

Hi, to answer this question we have to write system of equations with the information given:

The space each goat needs (4) multiplied by the number of goats (x); plus The space each llama needs (10) multiplied by the number of llamas must be less or equal to the acre land available (800)

4x +10y ≤ 800 (acres)

The amount of veterinary care (in $) each  goat needs (110) multiplied by the number of goats (x); plus The  amount of veterinary care   each llama needs (88) multiplied by the number of llamas (y)must be less or equal to the Rancher's budget.(14520)

110x +88y ≤ 14,520 (cost)

Multiplying the first equation by 27.5, and subtracting the second equation to the first one:

110x + 275y ≤22,000

-

110x +88y ≤ 14,520

____________

187y ≤ 7480

y ≤ 7480/187

y ≤ 40

Replacing y in the first equation

4x +10(40) ≤ 800

4x +400 ≤ 800

4x ≤ 800-400

4x ≤ 400

x ≤ 400/4

x ≤ 100
