Answer:
2.0491 watt per meter square
Step-by-step explanation:
We are given the following in the question:
The intensity of light is given by:

where W is the wattage of the light bulb and r is the distance to the light bulb.
We have to evaluate the intensity of bulb with W = 100 watts and r = 2 meters.
Putting values, we get,

Thus, the intensity of light bulb is 2.0491 watt per meter square.
Answer:
Perimeter = 21 units
Volume = 110 cubic units
Step-by-step explanation:
Let the center of circle be (x,y).

4x - 18y = - 45

4x + 8y = 4
x + 2y = 1
Solving these 2 equations,
4 - 26y = -45
y = 
x = 
radius = 3.35
Perimeter = 2
= 21 units
Volume of cylinder = 
We have to add the volumes of the cylinders.
Volume of smaller cylinder =
= 8
Volume of larger cylinder = 27 
Total volume = 35
= 110 cubic feet
Answer:
3.7
Step-by-step explanation:
To change a fraction to a decimal, just divide the numerator with the denominator. Instead of placing the remainder over the divisor, continue to solve until it is answered (unless it's a repeating decimal.)
Divide 7 with 10:
7/10 = 0.7
Remember that there is a whole number, 3. Add that to the decimal you have gotten:
3 + 0.7 = 3.7
3.7 is your answer.

128.34
= 128+ 0.34
= 128+ 34/100
= 128+ (34/2) / (100/2)
= 128+ 17/50
= 128 17/50
128.34 written as a mixed number is 128 17/50~
