How may more barrels of gasoline than diesel were produced last year? 500,000, 3,000,000, 5,000,000, 300,000,000, 500,000,000?

So Gasoline is - 34%

So Diesel is - 29%

To work out how many more barrels of gasoline to diesel you would do:

34% - 29% = 5%

So you would then convert 5% to a decimal and then multiply it.

0.05 x 60,000,000 = 3,000,000.

There will be 3,000,000 more barrels of gasoline.

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

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
