The "rule of 72" says that the doubling time in years is approximately 72 divided by the interest rate in percent. To make the money grow by a factor of 4 requires that it double twice, so will take twice as long as the period to double once.
2×72/11.3 ≈ 12.7 . . . . years
_____
The "rule of 72" is an approximation. The actual quadrupling time for this interest rate and compounding is about 12.6 years. (The actual product of doubling time and nominal interest rate is about 71.25.)
Answer:
Based on the converse of the Pythagorean Theorem, the triangle is not a right triangle, because 
Step-by-step explanation:
The complete question in the attached figure
we know that
If the length sides of a triangle, satisfy the Pythagorean Theorem, then is a right triangle

where
c is the hypotenuse (the greater side)
a and b are the legs
In this problem
The length sides squared of the triangle are equal to the areas of the squares
so


substitute

----> is not true
so
The length sides not satisfy the Pythagorean Theorem
therefore
Based on the converse of the Pythagorean Theorem, the triangle is not a right triangle, because 
Answer:
Option B. 
Step-by-step explanation:
we have

Solve for w
That means ----> isolate the variable w
Multiply by 5 both sides to remove the fraction

subtract 8 both sides


Rewrite

We have been given that Davis has 141 figures in his action figure collection. One-third of the figures are sports related.
To find the number of figures that are not sports related we will find 2/3 of 141 as 2/3 of the figures will be not related to sports.



Therefore, 94 figures in Davis’ collection are not sports related.
