To solve the problem, let us note that the calcium percentage no longer considers the moisture content of the canned dog food. Taking the 75% of the sample 681 grams results in a moisture content of 510.75. This is "removed" from consideration and we're left with 170.25 grams which we multiply with the given (dry basis) percentage of calcium to get 2.043 grams of Calcium.
Answer:
253.585 square inches
Explanation:
The figure can be decomposed into 2 rectangles and a quarter circle.
Area of the figure = area of rectangle 1 + area of rectangle 2 + area of ¼(circle)
✔️Area of rectangle 1 = Length × width
Length = 10 in
Width = 6 in
Area of rectangle 1 = 10*6 = 60 in²
✔️Area of rectangle 2 = Length × width
Length = 10 in
Width = 6 + 7 = 13 in
Area of rectangle 2 = 10*13 = 130 in²
✔️Area of ¼(circle) = ¼(πr²)
r = 9 in
π = 3.14
Area of ¼(circle) = ¼(3.14*9²) = 63.585 in²
✅Area of the figure = 60 + 130 + 63.585 = 253.585 square inches
In a Biology scientific report there will always be factors that change even if its by a little bit. In order to increase the “Reliability” of your conclusion or experiment you are required to do your experiment multiple times. Obviously in this case things such as the scale sensitivity will change according to the scale you use as well as if it is accurately set to scale but usually you will get a change in answer. The other thing you need to remember is that when the apple was originally measured they used another measuring tool to you therefore altering your answer ❤️

Basically the experiment has to be done with proper reasoning to make the scientific explanation satisfactory for all concerned. Scientific method is a process that is ongoing. Based on the observations via properly done experiments, a scientist can come to a proper conclusion. Although the procedures followed during experiment may vary, but the final result should always be the same. </span>
