To have a total mass of 1 googol kilograms, 1.674480911 × 10 ⁷⁵ earths are needed
How to determine how many earths are needed to have a total mass of 1 googol kilograms?
Given that:
1 googol = 10¹⁰⁰
Earth's mass is 5.972×10²⁴ kilograms
In order to find how many earths are needed to have a total mass of 1 googol kilograms, you need to divide 1 googol kilograms by Earth's mass (5.972×10²⁴ kilograms). Thus:
Number of earths needed = 10¹⁰⁰ / 5.972×10²⁴
Number of earths needed = 1.674480911 × 10 ⁷⁵ earths
Therefore, 1.674480911 × 10 ⁷⁵ earths are needed to have a total mass of 1 googol kilograms

Take sq. root on both sides
√y² = √169
y = ±13So,
y = 13 OR y = -13
[tex]\rule[225]{225}{2}[/tex]
Answer:
b) y = + 13
Step-by-step explanation:
Now we have to,
→ find the required value of y.
The problem is,
→ y² = 169
Let's solve the problem,
→ y² = 169
→ y = √(169)
→ [ y = + 13 ]
Hence, the answer is + 13.

The half-life of Radium-223 is 11.43 years. What is the annual decay rate? Express the result to four decimal places.
Express the annual decay rate as a percentage to two decimal places.
%
Answer:
Below
Step-by-step explanation:
e^(-kt) = 1/2 when t = 11.43
so k = .060642797
e^ (- .060642797 * 1) = .9411 <==== is left after one year
which means the decay in one year is
1 - .9411 = .05884 = 5.88% per year

The stereo normally priced at $299 is on sale for 15%off. Find the discount and the sale price.
Answer: Sale price: $254.15 , Discount: $44.85
Step-by-step explanation:
15% off indicates that the stereo will now cost 85% of what it did originally:
$299(100% – 15%) = $299(85%)

The Range of the length of a rectangle having fixed width and area increasing linearly is = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers,
What is a rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.
Given:
The width of the rectangle is fixed, and the length is changing.
The line is formed when connected through the graph.
The area of the rectangle = [tex]length\times width[/tex]
So when the width is fixed, the area would increase linearly and directly proportional to length.

If Two signs that scores are significantly different then (a) the error bars of group will not overlap
Error bars are graphical representations of data variability that are used to indicate the error or uncertainty in a reported measurement on graphs.
The estimated error in a measurement is indicated by error bars. In other words, an error bar represents the degree of uncertainty in a value.
When the standard deviation error bars overlap significantly, it is an indication that the difference is not statistically significant. To reach a conclusion, you must conduct a statistical test.
When the standard deviation error bars overlap even less, it indicates that the difference is unlikely to be statistically significant.
