Geometry help please

Answer:

CED = 117

Step-by-step explanation:

21x +21 = 7x +49

21x - 7x = 49 - 21

14x = 28

x = 28/14

x = 2

7x + 49

=7(2) + 49

=14 + 49

=63

180 -63 = 117

CED= 117

What is the equation simplified

Lilit [14]

$\bf \cfrac{2}{7}(2s+3)\implies \stackrel{\textit{distributing}}{\cfrac{2}{7}\cdot 2s+\cfrac{2}{7}\cdot 3}\implies \cfrac{2\cdot 2}{7}s+\cfrac{2\cdot 3}{7}\implies \cfrac{4}{7}s+\cfrac{6}{7}$

F=9/5(k-273.15)+32 what is F?

Delvig [45]

I believe you convert from Kelvin to Degree Fahrenheit
Kelvin is 293 so
F=9/5 (293-273.15)+32
F=9x5 (19.85)+32
F=45-19.85+32
F=57.15

A ball rolls over the edge of a platform with only a horizontal velocity. The height of the platform is 1.6 m and the horizontal

Sever21 [200]

Answer:

35 m/s

Step-by-step explanation:

Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m

$1.6 = 9.8t^2/2$

$t^2 = 2*1.6/9.8 = 0.327$

$t = \sqrt{0.327} = 0.571s$

This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s

v = 20 / 0.571 = 35 m/s
