Answer:
36.89°
Step-by-step explanation:
tan x = 15/20=3/4
x = 36.89
Answer:
10.5
Step-by-step explanation:
sin29
k
=
sin124
18
Plug in. Opposite sides go together.
k=\frac{18\sin 29}{\sin 124} \approx 10.526 \approx 10.5
k=
sin124
18sin29
≈10.526≈10.5
Answer:
The deep of the water would be 20 cm
Step-by-step explanation:
step 1
Find the volume of the water
The volume of the water is equal to
we have
substitute
step 2
Find the deep of the water, if the tank is returned to its horizontal position
(resting on its 60 cm × 100 cm base)
Now we have
substitute the given values
solve for H
therefore
The deep of the water would be 20 cm
It takes Selma 1/6 of a hour to run 3/4 miles.
Just multiply 3/4 by 6 to get 18/4 which is 4.5 miles or 4 1/2 mile
<em>x = 9</em>
<em>y = 0</em>
- Step-by-step explanation:
<em>y = -2x + 18 </em>
<em>4y - x + 9 = 0</em>
<em />
<em>4(-2x + 18) - x + 9 = 0</em>
<em>- 8x + 72 - x + 9 = 0</em>
<em>- 9x + 81 = 0</em>
<em>81 = 9x</em>
<em>x = 81 : 9</em>
<em>x = 9</em>
<em />
<em>y = - 2×9 + 18</em>
<em>y = - 18 + 18</em>
<em>y = 0</em>
