Lauren bought 6 yellow roses, 10 orange roses, and 12 pink roses to make a bouquet. what is the ratio of the number of yellow roses to the total number of roses in lauren’s bouquet?

1/12

Step-by-step explanation:

It asked for 6 yellow roses to 6.

Then it asked for the total so 6+10+12=72

6/72.

Then simplify it 6/6= 1

72/6= 12

So the answer is 1/12

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

b
