When a number is decreased by 4%, the result is 93. What is the original number
romanna [79]

Answer:

<u>The original number is 96.875</u>

Step-by-step explanation:

Let's find the original number using the Direct Rule of Three, this way:

       Percentage          Number

              100                       x

               96                       93

***********************************************

96x = 93 * 100

96x = 9,300

x = 9,300/96

x = 96.875

<u>The original number is 96.875</u>

Consider the series 4 + 12 + 36 ... Find the sum of the first 9 terms.​
jeyben [28]

Answer:

39364

Step-by-step explanation:

You can simplify the equation to make 4(1+3+9...) The nth term is therefore 3^{n-1} so u can substitute that into the equation so 4(3^{n-1}+ 3^{n}  + 3^{n+1}..). This would simplify to 4(3^0 +3+3^2+3^3+3^4+3^5+3^6+3^7+3^8). By simplifying this, you can make it so 4(2^2+6^2+18^2+42^2+81^2) = 4(4+36+324+2916+6561) =39364

If the circumference of a circle is 12, and the angle measure of an arc is 60o, which is the length of the arc?
Kaylis [27]
We can get the measurement of the arc by determining first the radius of the circle. The circumference of a circle is equal to 2 * pi * radius. Hence from a 12 unit2 circumferenced circle, the radius is 1.91 units.Length of the arc is equal to radius times the angle in radians. 60 deg is equal to pi over 3. The length of the arc is equal to 2 units.
