A water sample shows 0.073 grams of some trace element for every cubic centimeter
of water. Anthony uses a container in the shape of a right cylinder with a diameter of
11.4 cm and a height of 16.5 cm to collect a second sample, filling the container all the
way. Assuming the sample contains the same proportion of the trace element,
approximately how much trace element has Anthony collected? Round your answer
to the nearest tenth.
The amount of trace element has Anthony collected, assuming the sample contains the same proportion of the trace element, is 114.6 grams.
What is of volume of cylinder?Volume of cylinder is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
The volume of cylinder can be given as,
[tex]V=\dfrac{\pi r^2h}{4}[/tex]
Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.
A water sample shows 0.073 grams of some trace element for every cubic centimeter of water. The proportion of element with water is,
[tex]p=\dfrac{0.073}{1}[/tex]
Anthony uses a container in the shape of a right cylinder with a diameter of 11.4 cm and a height of 16.5 cm to collect a second sample, filling the container all the way.
The total volume of the container is,
[tex]V=\dfrac{\pi (11.4)^2\times16.5}{4}\\V\approx1684 \rm\; cm^3[/tex]
The sample contains the same proportion of the trace element. Let the trace element has Anthony collected is x. Thus,
[tex]\dfrac{x}{1684-x}=\dfrac{0.073}{1}\\x=122.932-0.073x\\x+0.073x=122.932\\x=\dfrac{122.932}{1.073}\\x\approx114.6\rm\; gram[/tex]
Thus, the amount of trace element has Anthony collected, assuming the sample contains the same proportion of the trace element, is 114.6 grams.

If you spin the spinner 36 times, what is the best prediction possible for the number of times it will not land on yellow?
The best prediction for the number of times it will not land on yellow would be 29 times.
We have,
Assuming the spinner has an equal probability of landing on each color, The probability of it not landing on yellow is 4/5.
So,
If you spin the spinner 36 times, the expected number of times it will not land on yellow is:
= (4/5) x 36
= 28.8
Since you can't have a fraction of a spin,
= 28
Thus,
The best prediction for the number of times it will not land on yellow would be 29 times.

Write f(x)=|x-2| as a piecewise function.
Answer:
Hi! A piecewise function is a function defined by multiple sub-functions, or pieces of different functions over different intervals. Piecewise definition is a way of expressing the function and is not actually integral to the function itself.
f(x) = |x - 2| is an absolute value function. As a piecewise function, it's written like this:
f(x) = {x - 2, x ≥ 2
{-x + 2, x < 2
Hope this helps! Have a great day.
The population of a bacteria colony doubles every 6 hours. For example, starting with a sample of 10 bacteria, after 6 hours there would be 20 bacteria and so on. After 12 hours there would be 40, and so on. Now consider a scientist who has collected a colony of 25 bacteria. Create an expression and approximate the number of bacteria after 3 hours.
Answer:
If the bacteria grow for six hours, each bacterium will divide 3 times per hour × 6 hours = 18 times.
Every time the bacteria reproduce, the number doubles.

The area of a parallelogram is given by the formula A=bh. The area of the parallelogram is 85 sq. Units. Find it’s base and height.
Answer:
the height is 5 and the base is 17.
Step-by-step explanation:
X + 1 is the height and 4x + 1 is the base, so we can substitute this into an equation:
( x + 1 ) (4x + 1) = 85
{apply the distributive law}
4x² + x + 4x + 1 =
4x² + 5x + 1 = 85
Take 85 to the other side by -85 each side:
4x² + 5x + 1 - 85 = 85 - 85
4x² + 5x - 84 = 0
{Now we have a quadratic equation}
The roots are either -5.25 or 4. X must be 4 since it must be positive as it is a side length.
Substitute x into the base and height to get the answers.
X + 1 = 4 + 1 = 5
4x + 1 = 16 + 1 = 17
Therefore the height is 5 and the base is 17.

43.98 ft
hope it helps...!!!
Answer:

Step-by-step explanation:
We are given that the diameter is 14 ft.
The radius is half the diameter, so the radius is 7 ft.
Now, the formula for circumference is: 2πr
So: 2 * π * (7) = 43.98
Round: 43.98 >> 44.0

midnight
the temperature had dropped
18°, What was the temperature
at
midnight?
A. 1°F
C.-37°F
B.-1°F
D.37°F
Answer:
C.
Step-by-step explanation:
Since you are subtracting a positive from a negative, your absolute value will get greater. With negative numbers, the less they become in value, the higher their absolute value will get. So, since we are subtracting a positive from a negative, we add them together. However, we need to add them as if they were both positive signs.
Once you do this:
19
+18
You should get 37. Since -19 has a greater absolute value than 18, you keep the negative sign and apply it to 37, getting you -37.
