Answer:

33.22 square inches

Step-by-step explanation:

Diameter to Radius: \frac{1}{2}d = r

Area of Circle: \pi r^2

We are given the diameter of a pancake as 4.6 inches, so the radius is 2.3 inches. Next, we have to apply the area of circle formula with pi as 3.14 and the radius as 2.3

  • 3.14 * 2.3^2
  • 3.14 * 5.29
  • 16.6106

Next, since there's two pancakes, we double 16.6106.

  • 16.6106 * 2
  • 33.2212

Lastly, we round to the nearest hundredth.

  • 33.2212 ≈ 33.22 square inches

Therefore, the answer is 33.22 square inches.

_____ refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.
Setler79 [48]

Answer:

Internal validity

Step-by-step explanation:

Internal validity is a scientific study that emphasize on the fact that there is a proof to validate a specific study. Let's say i'm a forensics scientist for example; and there was a recent crime scene in some nearby sub-urban area which demands our call, when present at the scene, The main task there is to gather information as much as we can  which is required to be investigate in the laboratory for further analysis.The process of information gathering is our independent variables which varies with different causes of the crime, the laboratory analysis that make deductions (which is cause by some manipulation) of the information gathered is our dependent variables.

Therefore, we can conclude that Internal validity refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.

Could someone please explain to me how to determine the answer to this question?
dexar [7]

Concept: Solution of the given attachment is based on the addition of two vectors as given below.

Consider two vectors P and Q, then resultant of these two vectors is given as,

R = P + Q

To find the addition of G & H vectors. That is G + H =?

In the given figure;

Vector A = - Vector G because both are in opposite directions -----(i)

From the figure,

A + H = F --------------- using the given concept ---------(ii)

Now, shall replace the value of A from equation (i) in equation(ii)

- G + H = F

or, G + (- H) = - F

Since the vector addition of G & H is not equal to F.

Hence, the given statement G + H = F is False.

How many times longer is the diameter of a grain of sand than the diameter of the average cell in the human body? Show your work
oee [108]
<span>A grain of sand has a diameter of slightly over 1 mm and the average diameter of a human cell is 8 micrometers. Putting them into common terms (meters) gives: 1.03 * 10^-3 m and 8*10^-6 m, respectively. Dividing the two to give a ratio leads to a value of (1.03*10^-3)/(8*10^-6), or 128.75 times longer for the grain of sand.</span>
