June and stella can each create six floral arrangements in one hour. if they take in 372 valentineâs day orders, how many hours will they need to fulfill them?

31 hours

Step-by-step explanation:

June and Stella can create 6 floral arrangements in one hour.

They take in 372 Valentine's Day order

No of hours = orders / (June's rate + Stella's rate)

June's rate = 6 arrangements / hour

Stella's rate = 6 arrangements / hour

June's rate + Stella's rate = 2(6 arrangements /hour)

= 12 arrangements / hour

No of hours = 372 arrangements / 12 arrangements / hour

= 31 hours

June and Stella have 31 hours to fulfill the 372 Valentine's Day order

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
