Answer:
1. -9x+by=1 Answer : x=- 1/9 + by/9.
2. For 3x=2y=2, the answer is...
Exact form : x=29/3
Decimal for : x=9.666666666666666...
Mixed Number form : x=9 2/3
Step-by-step explanation:
1. Isolate the variable by dividing each side by factors that don't contain the variable.
2. Move all terms that do not contain x to the right side and then solve.

Answer:
The volume of the cylinder is 2520.64ft³
Step-by-step explanation:
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 19ft
π = 3.14
r = radius = 6.5ft
v = (π * r²) * h
we replace with the known values
v = (3.14 * (6.5ft
)²) * 19ft
v = (3.14 * 42.25ft²) * 19ft
v = 132.665ft² * 19ft
v = 2520.64ft³
The volume of the cylinder is 2520.64ft³
Solution:
<u>Note that:</u>
- Area of triangle = 6 3/8 yd²
- Height of triangle = 2 1/2
- Area of triangle = 1/2 x base x altitude
<u>Use the formula to find the base of the triangle.</u>
- 1/2 x base x altitude = 6 3/8 yd²
- => 1/2 x base x 2 1/2 = 6 3/8 yd²
- => 1/2 x base x 5/2 = 6 3/8 yd²
- => 5/4 x base = 6 3/8 yd²
- => base = 6 3/8 ÷ 5/4 yd
- => base = 51/8 x 4/5 yd
- => base = 51/2 x 1/5 yd
- => base = 51/10 yd
The length of the base is 51/10 yards.
Answer:
Step-by-step explanation:
Domain of a cosine is all real numbers.
Therefore the domain of F(x) = 2cos(3x - 1) is the set of all real numbers.
The answer is 32 because 25 +6 is 31 and 1000÷31 is 32
