Answer:
0.48
Step-by-step explanation:
The range of a data set is the largest quantity subtracted by the smallest quantity. In this case 1.61 is the smallest. 2.09 is the largest. So we need to do 2.09-1.61 and get the range of 0.48! Stay safe!
2 3/8 x 1/3 I believe? First you need to change 2 into a 16 then add that into 3 which is 19/8. You multiply across with 1/3 like with numerator with numerator and denominator with denominator. That then equals:19/24. You can't estimate it because 19 is a prime number.
An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
Isolate the x. First, multiply 2 to both sides
-x/2(2) < 4(2)
-x < 4(2)
-x < 8
Isolate the x. Divide - 1 to both sides (because you are dividing a negative number, flip the sign).
-x/ -1 < 8/-1
x > -8 is your answer
hope this helps
