A 90-kg astronaut biologist searches for microbial life on Mars where the gravitational acceleration is g = 3.71 m/s2. What is t
Yuki888 [10]
M = 90 kg,
On Mars:  g = 3.71 m/s² 
Weight = m · g = 90 kg · 3.71 m/s² = 333.9 N
1 N = 0.2248 lbf
333.9 · 0.2248 = 75.06072 lbf ≈ 75 lbf

A tent forms an equilateral triangular prism, with both triangular faces exposed. each side of the triangular face has a length
Soloha48 [4]
Given:
Equilateral Triangular Prism
Each side of the triangular face has a length of 196cm
The tent is 250cm long

I have attached an image of the tent. Since the height of the tent is also the height of the triangle, I will solve for the height of the triangle using Pythagorean theorem.

I divided the equilateral triangle into 2 right triangle. The height then becomes the long leg of the triangle. The hypotenuse is 196cm and the short leg is 98cm, half of one side of the triangle.

a² + b² = c²
a² = c² - b²
a² = (196cm)² - (98cm)²
a² = 38,416cm² - 9,604cm²
a² = 28,812cm²
a = √28,812cm² 
a = 169.74cm

The height of the tent is 169.74 centimeters.

The figure below shows square ABCD inscribed on square PQRM on a coordinate plane. Which of the following expressions represents
vova2212 [387]
The hypotenuse of the triangle is given by:
 CB ^ 2 = RC ^ 2 + RB ^ 2

 Substituting values:
 CB ^ 2 = 2 ^ 2 + 4 ^ 2

 Clearing CB we have:
 CB = \sqrt{ 2 ^ 2 + 4 ^ 2}  

 CB = \sqrt{ 4 + 16}  

 CB = \sqrt{20}  

 CB = \sqrt{4*5}  

 CB = 2\sqrt{5}  




 Then, the perimeter of the triangle is:
 P = RB + RC + CB

 Substituting values:
 P = 4 + 2 + 2 \sqrt{5} 

 P = 6 + 2 \sqrt{5}
 Answer:
 the perimeter of triangle BRC in units is:
 D.6 + 2√5

Answer:

I got 20

Step-by-step explanation:
