PLEASE HELP ASAP! A mountain climber is at an altitude of 2.9 mi above the earth’s surface.

shutvik [7]

You can use Pythagorean theorm to solve.

$a^2 + b^2 = c^2$
C = 3959 + 2.9 = 3961.9

x = ???? = a
b = 3959
Plugin our data.
$a^2 + b^2 = c^2$
$a^2 + 3959^2 = 3961.9^2$
$a^2 + 15673681 = 15696651.61$
$a^2 = 22970.61$
$\sqrt{a^2} = sqrt{22970.61}$
$a = 151.560$
$x = 151.560$
$x = 151.6$

3/7 of which is 2 1/14

mash [69]

Answer:

4 and 5/6; 29/6.

Step-by-step explanation:

3/7 of x is 2-1/14.

(3/7)x = 29/14

x = (29/14) * (7/3)

x = (29/2) * (1/3)

x = 29/6

3/7 of 4 and 5/6 is 2 1/14.

Hope this helps!
