Aroad sign says that there is an exit in 3/4 of a mile. how many metres is this? (use the unit conversions in your formula sheet). answer to the nearest whole number.

common imperial imperial and si si

1 mile = 1760 yd. 1 mile = 1.609 km. 1 km = 1000 metre
1 mile = 5280 ft. 1 yard = 0.9144 m. 1 metre = 100 cm.
1 yard = 3 ft. 1 foot = 30.48 cm. 1 cm = 10 mm.
1 yard = 36 in. 1 inch = 2.54 cm.
1 foot = 12 in.

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
