Danesh is incorrect as the multiplication of 1.496 × 1011 and 6.68 × 109 results in a value with 1020, not 1099. Moreover, 1 googol equals 1 × 10100, which is much larger.
Explanation:No, Danesh is incorrect. According to the laws of exponents, when you multiply two powers with the same base, you add the exponents. Therefore, the multiplication of 1.496 × 1011 and 6.68 × 109 will result in a value that is multiplied by 1020 and not 1099. Also, 1 googol is significantly larger than the result of this multiplication because it is equal to 1 × 10100. Thus, the statement made by Danesh is inaccurate.

if the area of the circle measures 9/4 Pi sq cm square what is the circumference of the circle in the terms of Pi
Answer:
c = 3πcm
Step-by-step explanation:
from the question area of the circle is given to b 9/4 πcm²
circumference of the circle in terms of π = ?
the formula for finding the Area of a circle = πr²
Since the area was given to be
(9/4)π = πr²
divide both sides by π
we have
9/4 = r²
we apply the cross multiplication rule
so we have,
4r² = 9
divide both sides by 4
r² = 9/4
r = √9/4
r = 3/2
now to find the circumference of the circle , we apply the formula for finding the circumference of a circle which is
c = 2πr
from our calculations radius r = 3/2
c = 2 ( π × 3/2) [ 2 cancels 2]
c = 3πcm
4- x2 =-32
The equation above is true for what value of x, where
x>0?
Answer:
x= -6
Step-by-step explanation:
first you want to get rid of the 4 so on both sides you subtract 4
4-x²=-32
-4 -4 that will then make the problem
-x²= -36 to get rid of the square you must do the opposite, square root ([tex]\sqrt{36}[/tex]) so it will get rid of the ²
-x= 6 then you have to get rid of the neggative on x so you will add a negative to 6
x=-6

Step-by-step explanation:
A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degrees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored. What is a strong counterargument?
Even 0.08 degrees is a lot and thus should be considered.
The margin of error is just extra information and thus can be ignored.
The difference with any previous decade is much greater than the margin of error.
0.15 - 0.08 is 0.07, which is still an increase and thus should be considered
The difference with any previous decade is much greater than the margin of error.
In statistics, the margin of error refers to half the confidence interval. It measures how much of a random sample does not fall within the confidence interval as the number of samples taken increases indefinitely. Because the margin of error depends on the level of confidence, multiple margins of error are available from the same data set.
Thus, although year after year the temperature difference is within the margin of error contemplated in the study, the truth is that the sum of several years shows differences that are not included within this margin, which proves that climate change is real and its negative effects are too.

Final answer:
Long-term data analysis shows a clear warming trend in global temperatures over the past century, significantly exceeding the margin of error. The increased frequency of warm temperatures and the scientific consensus among multiple groups validate the occurrence of anthropogenic global warming.
Explanation:
A strong counterargument to the media personality's claim that global temperatures are not rising because the yearly increase is within the margin of error is to emphasize the long-term trend and robustness of the data. Examination of global temperature trends over longer periods clearly shows that, even with margins of error considered, there has been a significant increase in global temperatures.
For instance, averaged over land and ocean, Earth's temperature over the past century has increased by approximately 0.7°C, a result that multiple groups worldwide have corroborated using various analytical methods. This consensus adds strength to the argument. When comparing temperature differences with previous decades or even centuries, the change significantly exceeds the margin of error, revealing a clear warming trend.
Moreover, the probability of warm and extreme warm temperatures has increased, while the probability of cold and extreme cold temperatures has decreased, supporting the conclusion that anthropogenic global warming is occurring and substantiating its impact beyond the bounds of statistical uncertainty.

In 2000, the total amount of a certain bird population (species of bird of paradise) was recorded at 47,000 in a city. In 2005, the same survey was made and the same bird population was estimated at 59,000. If the trend continues, in what year will the bird population reach 100,000? (Round to the nearest year)
Exponential growth is the process through which quantity rises over time. The population of the birds will reach 100,000 in 16.6 years from 2001.
What is exponential growth?Exponential growth is the process through which quantity rises over time. It happens when the instantaneous rate of change of a quantity with respect to time is proportionate to the amount itself.
In 2000, the total amount of a certain bird population (species of bird of paradise) was recorded at 47,000 in a city. In 2005, the same survey was made and the same bird population was estimated at 59,000.
As per the given information the population of the bird changed from 47,000 to 59,000 in five years, therefore, we can write,
59,000 = 47,000(1+r)⁵
(59/47) = (1+r)⁵
1.046528 = 1+r
r = 0.046528
Now, the time it will take for the population to reach 100,000 will be,
100,000 = 47,000(1+0.046528)ⁿ
[tex]\dfrac{\log(\frac{100}{47})}{\log{1.046528}} = n\\\\n = 16.6019[/tex]
Thus, the population of the birds will reach 100,000 in 16.6 years from 2001.

Final answer:
Using the given data, the bird population is increasing at a rate of 2,400 birds per year. If this rate continues, the population is expected to reach 100,000 by the year 2022.
Explanation:
The question involves calculating the year when the bird population will reach a certain number, assuming a consistent growth pattern. Based on the data provided:
Population in 2000: 47,000Population in 2005: 59,000First, determine the annual growth rate over the 5-year period from 2000 to 2005:
Growth = 59,000 - 47,000 = 12,000 birds
Annual growth rate = Growth / 5 years = 12,000 / 5 = 2,400 birds/year
Next, calculate the number of years needed for the population to grow from 59,000 (in 2005) to 100,000:
Number of years = (Target population - Population in 2005) / Annual growth rate
= (100,000 - 59,000) / 2,400
≈ 17.08 years
To find the target year, add the number of years to 2005 and round to the nearest year:
Target year = 2005 + 17.08 ≈ 2022
Therefore, if the trend continues, the bird population is predicted to reach 100,000 in 2022

Crude Oil Production Breakdown for Last Year
Kerosene: 14%
Lubricating Oil: 5%
Gasoline: 34%
Other Products: 18%
Diesel: 29%
Total production from Crude oil - 60 million barrels
Question 1 of 3
What was the total production of Gasoline and Kerosene combined (in
barrels)?
288,000 480,000 26.4 million * 28.8 million
48 million
Answer:
28.8 million barrels.
Step-by-step explanation:
The percentage of production of Gasoline and Kerosene from Crude oil are 34% and 14%.
So, the Gasoline and Kerosene is totally produced by (34 + 14) = 48%.
If the production of Crude oil is 60 million barrels, then the production of Gasoline and Kerosene combined from this amount of Crude oil will be
[tex]60 \times \frac{48}{100} = 28.8[/tex] million barrels. (Answer)
By taking the sum of the percentages of Gasoline and Kerosene from the total crude oil production, we find that 48% of the 60 million barrels produced was Gasoline and Kerosene, which equates to 28.8 million barrels.
Explanation:The total production from Crude oil is given as 60 million barrels. The total percentage of Gasoline and Kerosene is obtained by adding the individual percentages. Gasoline is 34% and Kerosene is 14%, so the total is 48%.
To find the total production of Gasoline and Kerosene, we must multiply this percentage by the total production.
Calculation: 48/100 * 60 million = 28.8 million barrels
So, the total production of Gasoline and Kerosene combined was 28.8 million barrels.

Answer:
The height is 5 in
Step-by-step explanation:
V = l*w*h
Substitute in what we know
360 = 24 *3*h
360 = 72h
Divide each side by 72
360/72 = 72h/72
5 = h
The height is 5 in
Answer:
The height is 5 inches
Step-by-step explanation:
Knowing that he volume of a rectangular prism is V = L*W*H, it is given that V = 360, L = 24, and W = 3. Substitute these values into the equation and get 360 = 24*3*H. This can simplify to 360 = 72*H and by dividing both sides by 72, you get H = 5. This means that he height is 5 inches.

a total of 9 apples and bananas altogether. Determine the number of apples and the
number of bananas that Alexandra bought.
Answer:
[tex]\large \boxed{\text{3 apples and 6 bananas}}[/tex]
Step-by-step explanation:
Let a = the number of apples
And b = the number of bananas. Then,
[tex]\begin{array}{rcll}(1) \, 1.75a + 0.40 b & = & 7.65&\\(2)\, \, \, \, \quad \qquad a + b & = &9&\\(3) \, 0.40a + 0.40b & = &3.60&\text{Multiplied (2) by 0.40}\\1.35a & =&4.05\\(4) \, \, \quad \qquad \qquad a & =& \mathbf{3}&\text{Divided each side by 1.35}\\3 + b & = &9& \text{Substituted(4) into (2)}\\b &=& \mathbf{6}&\text{Subtracted 3 from each side}\\\end{array}\\\text{They bought $\large \boxed{\textbf{3 apples and 6 bananas}}$}[/tex]
Check:
[tex]\begin{array}{cccl}3(1.75) + 6(0.40) = 7.65 & \qquad & 3 + 6 = 9\\5.25 + 2.40 = 7.65 & \qquad & 9 = 9\\7.65 = 7.65 & \qquad & \\\end{array}[/tex]
OK.
Alexandra bought 3 apples and 6 bananas
Number of apples = a
Number of bananas = b
From the information given, the equation to use will be:
a + b = 9 ....... i
1.75a + 0.40b = 7.65 ...... ii
From equation i, a = 9 - b ...... iii
Put equation iii into ii
1.75a + 0.40b = 7.65
1.75(9 - b) + 0.4b = 7.65
15.75 - 1.75b + 0.4b = 7.65
Collect like terms
-1.75b + 0.4b = 7.65 - 15.75
-1.35b = -8.1
b = 8.1/1.35
b = 6
She bought 6 bananas
Number of apples bought = 9 - 6 = 3 apples.
Therefore, Alexandra bought 3 apples and 6 bananas
