Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
Answer:
0.0111 grams with the one repeating
Step-by-step explanation:
yeet
first brand quantity is x
2nd brand quantity is y
x+y=30
0.3x+0.55y=0.35(30) or 0.3x+0.55y=10.5
solve for x and y
multiply first equation by -0.3
-0.3x-0.3y=-9
add to 2nd equation
0.3x-0.3y=-9
<u>0.3x+0.55y=10.5 +</u>
0x+0.25y=1.5
0.25y=1.5
divide both sides by 0.25
y=6
sub back
x+y=30
x+6=30
x=24
you need 24 gallons of the first brand and 6 gallons of the 2nd brand
I'll assume the ODE is actually

Look for a series solution centered at
, with



with
and
.
Substituting the series into the ODE gives





- If
for integers
, then




and so on, with

- If
, we have
for all
because
causes every odd-indexed coefficient to vanish.
So we have

Recall that

The solution we found can then be written as


First, you need to find the area of the room.
299×34=10166
Once you found the area of the room, you need to find the cose of the tile.
10166×11=111826
It will cost $111,826 to cover 10166 square feet.
