12 pi inches is the circumference
Answer:
The length is <u>8</u> ft.
The width is <u>2</u> ft.
Step-by-step explanation:
A = l*w
l = w + 6
16 = w(w + 6)
16 = w^2 + 6w
w^2 + 6w - 16 = 0
(w + 8)(w - 2) = 0
w = -8ft or 2ft
Since lengths cannot be negative in reality, <u>w = 2ft</u>.
l*2 = 16
<u>l = 8ft</u>
Answer:
The approximate temperature of the preheated oven is 204 °C.
Step-by-step explanation:
Here, the given temperature in Fahrenheit = 400 °F
Let us assume the given temperature in Celsius = C
Now, the relation between the two measure of temperature is given as:
According to the question:
Or, C = 204.4°C
Hence, the approximate temperature of the preheated oven is 204 °C.
1 - 7x = -20 |subtract 1 from both sides
-7x = -21 |divide both sides by (-7)
x = 3
The types of validity that were not established in this study is internal validity and the Reasonably not met are: external, construct, statistical.
<h3>What is Internal Validity? </h3>
Internal validity can be described as the extent that a particular study can bring about the establishment of a trustworthy cause-and-effect relationship which can be set between the treatment as well as the outcome.
In conclusion, Internal validity let us understand that a study can makes it possible to eliminate alternative explanations as regards finding, hence The types of validity that were not established in this study is internal validity and the Reasonably not met are: external, construct, statistical.
