A and b are positive integers and a-b=2. Evaluate the following: 9^1/2b/3^a

OlgaM077 [116]

Answer:

$\frac{1}{ 9 }$

Step-by-step explanation:

$\huge \frac{ {9}^{ \frac{1}{2}b } }{ {3}^{a} } \\ \\ = \huge \frac{ {( {3}^{2} )}^{ \frac{1}{2}b } }{ {3}^{a} } \\ \\ = \huge \frac{ { {3}}^{2 \times \frac{1}{2}b } }{ {3}^{a} } \\ \\ \huge = \frac{ {3}^{b} }{ {3}^{a} } \\ \\ \huge = \frac{1}{ {3}^{a - b} } \\ \\ \huge= \frac{1}{ {3}^{2} } \\ ( \because \: a - b = 2)\\ \\ \huge = \frac{1}{ 9 }$

When a number is decreased by 4%, the result is 93. What is the original number

romanna [79]

Answer:

The original number is 96.875

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

The original number is 96.875

How do you find an area of a triangle when you just have two sides and an angle?

Olenka [21]

You have to use sin, cos, tan and find the length of the last side and other angles. Then you have to put an imaginary line down the middle and use the sin, cos, tan to find the height and then do 1/2 base times height.
