Set up a proportion!

40 minutes / 5 holes = m minutes / 20 holes

Cross multiply.

800 = 5m

m = 160.

It will take him 160 minutes to dig 20 post holes.

Good luck Fabian!

Hope this helps

Find x. Round your answer to the nearest tenth of a degree.<br> Lo<br> 40

asambeis [7]

Answer:

x = 62.3 degrees.

Step-by-step explanation:

We should notice a certain trigonometric function that works here.

tan x = opposite side / adjacent side

tan x = 40/ 21

x = arctan (40/21) = 62.3005 degrees

x = 62.3 degrees.

So 20=2 itmes m2 times 5

5m=5 times m

so
5m=20
5 times m=2 times 2 times 5
divid eboth sides y 5
m=2 times 2
m=4

Graph the line with slope −1/2 and y-intercept −5.

Allushta [10]

First, we can write the equation of the line using the information provided:

$\begin{gathered} y=mx+b \\ where: \\ m=slope=-\frac{1}{2} \\ b=y-intercept=-5 \\ so: \\ y=-\frac{1}{2}x-5 \end{gathered}$

Now, we can create a table:

Finally, we can graph the line:
