Answer:

I don't know the question you are asking but her's how to find the answer...

Step-by-step explanation:

First, you have 20$ per hour. Next you would need the total number of hours they worked. Then, you would multiply 20 by the hours worked and then your answer would be the money that was earned.

Heres an example:

Ernesto worked 8 hours today and earns 20$ for each hour he works. How much did he make?

20*8= 160

$160 would be the answer

Hope this helps!!!

insens350 [35]

Answer:

19.3795 m

Step-by-step explanation:

If sound travels at 343 m/s and it took Karen 0.113 s to hear the echo from the wall, the distance travelled by the sound is:

$D=343\frac{m}{s} *0.113\ s\\D= 38.759\ m$

Note that the distance calculated above is the distance travelled from Karen to the wall and then back from the wall to Karen. Therefore, the distance between Karen and the wall is:

$d=\frac{38.759}{2}\\d=19.3795\ m$

The wall is 19.3795 m away from Karen.

Answer:

In the figure below :

d = 2.08, e = 5, c = 5.42 , a = 22.78°, b = 67.22°

Step-by-step explanation:

Side lengths :

$2\cdot e=10\\ \Rightarrow e=5 feet\\\frac{d}{e}=\frac{5}{12}\\\Rightarrow d=\frac{25}{12}\approx 2.08 feet$

By pythagoras theorem,

$c^2=d^2+e^2\\c^2=29.33\\c\approx 5.42 feet$

Now to find angles,

$a+b+90^{\circ}=180^{\circ}\\\Rightarrow a+b=90^{\circ}\\\tan a=\frac{d}{e}\\\Rightarrow \tan a =0.42\\\Rightarrow a=22.78^{\circ}\\\Rightarrow b=67.22^{\circ}$

Find the measure of c. A. 40 B. 70 C. 90 D. 50

Juliette [100K]

Answer:

D. 50

Step-by-step explanation:

a = 90° (angle subtended in semicircle)

a + c + 40° = 180° (by angle sum postulate of a triangle)

90° + c + 40° = 180°

c + 130° = 180°

c = 180° - 130°

c = 50°

Can you answer this, please?

Answer:

one of the red things

Step-by-step explanation:

if you subtract two red things from each side, you are left with two red things on one side and two E-tanks on the other. Then you can square root each side to find that one red thing equals one E-tank. Sence we don’t know the value of the red thing, this is as far as we can go
