Answer:

Answer:160 miles


Explanation:

You can work out this type of question by using the 'unitary' method, which means finding out how much for ONE.


If you set out the steps with short sentences it will be clearer.


 

On 15 gallons, a car can travel 400 miles÷15↓

On 1 gallon, a car can travel 400÷15=262


miles


Once you know the distance travelled on 1 gallon of fuel, you can work out the distance travelled for any number of gallons.


 

On 6 gallons the car can travel

26

miles.

(6 times further than on 1 gallon)

×

80

=

160

miles

Which of the following equations is equivalent to log(y)= 3.994 ?
Kisachek [45]

Answer:

The correct answer is option D: y = 10^{3.994}

Step-by-step explanation:

Given:  

log(y)= 3.994

Solution:

A logarithm base b of a positive number x satisfies the following definition:

y =log_b(x) => b^y =x

For x > 0, b >0, b \neq 1

Also if no base  b  is indicated, the base of the logarithm is assumed to be  10 .

Thus, in log(y)= 3.994 base b is not indicated. so its base is assumed to be 10

now

log_{10}(y)= 3.994

Then

y = 10^{3.994}
