The sides of a triangle are 9,11,13.The largest side of a triangle like this is 39.The other two sides of the second triangle are?
A) 18;22 B)27;33 C)3;11 3 D)48;50

Length of other two sides is 27:33

Option B

Step-by-step explanation:

Here we have , The sides of a triangle are in ratio 9:11:13.The largest side of a triangle like this is 39. Let's calculate other two sides of the second triangle:

is the ratio  ,largest ratio value is 13 which represents largest side ratio whose length is 39 :

⇒

⇒

⇒

Now, other two sides are 9 x and 11 x

i.e.

So, lengths of all the three sides are 27:33:39 . And, Length of other two sides is 27:33`

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
