1/2 divided by 4=2

4/4=1

6.5/4=1.625

2) x+1

1/2+1=3/2

4+1=5

Margaret drives 188 miles<br> with 8 gallons of gas. Find the unit rate

8090 [49]

The unit rate will be "23.5 miles/gallon". In the below segment, a further solution to the given question is provided.

Given values in the question are:

Total distance,

= 188 miles

Total gas used,

= 8

Now,

⇒ The rate of gas consumption will be:

= $\frac{Total \ distance}{Total \ gas \ used}$

By putting the given values in the above formula, we get

= $\frac{188}{8}$

= $23.5 \ miles/gallon$

Thus the above is the appropriate solution.

Write a relationship for a function whose k(x) values are 5 more than four times the principal square root of x .

bearhunter [10]

Answer:

$k(x)=5+4\sqrt{x}$

Step-by-step explanation:

Write a function whose k(x) values are 5 more than four times the principal square root of x.

So,

the principal square root of x $=\sqrt{x};$

four times the principal square root of x $=4\sqrt{x};$

5 more than four times the principal square root of x $=5+4\sqrt{x};$

Thus,

$k(x)=5+4\sqrt{x}$
