The blue lake trail is 11 3/8 miles long. Gemma has hiked 2 1/2 miles each hour for 3 hours. How far is she from the end of the
melomori [17]
In the question it is given that the length of the blue lake trail is 11 3/8 miles. In the question it is also given that Gemma has hiked for a total time of 3 hours and each hour she has hiked 2 1/2 miles.
Now coming to solving the problem we get:
Total length of blue lake trail = 11 3/8 miles
                                             = 91/8 miles
Distance hiked by Gemma in 1 hour = 2 1/2 miles
                                                           = 5/2 miles
Then the total distance hiked by Gemma in 3 hours = (5/2) * 3
                                                                                   = 15/2 miles
The distance left to cover the full trail = (91/8) - (15/2) miles
                                                            = (91 - 60)/8 miles
                                                             = 31/8 miles
                                                             = 3 7/8 miles.
So Gemma is 31/8 miles or 3 7/8 miles from the end of the trail.

Isolate the variable to find the solution of the equation. 6. 2w = 18. 6 w = 3 w = 12. 4 w = 24. 8 w = 115. 32.
Anarel [89]

An equation is formed of two equal expressions. The solution of the equation is w=3.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

In order to solve the equation, we need to isolate the variable in the following manner, therefore, the solution of the equation can be written as,

6.2w=18.6

Divide both sides of the equation by 6.2,

6.2w=18.6\\\\\dfrac{6.2w}{6.2}=\dfrac{18.6}{6.2}\\\\w = 3

Hence, the solution of the equation is w=3.

A university's freshman class has 5000 students. 90% of those
exis [7]

Answer:

4,500

Step-by-step explanation:

To find the number of students majoring in economics, you must turn 90% into a decimal making it .9.

Then you multiply the decimal to how many students there are (5000x.9) and that gives you 4,500.

Y=f(x)=x^2+x <br> find the slope of the secant line joining (-3,f(-3)) and (0,f(0))
Sergeeva-Olga [200]

Answer:

-2

The problem:

y=f(x)=x^2+x

find the slope of the secant line joining (-3,f(-3)) and (0,f(0))

Step-by-step explanation:

We need to first find the values that correspond to f(-3) and f(0).

f(-3) can be found by replacing the x's in f(x)=x^2+x with (-3):

f(-3)=(-3)^2+(-3)

f(-3)=9+-3

f(-3)=6

f(0) can be found by replacing the x's in f(x)=x^2+x with (0):

f(0)=(0)^2+(0)

f(0)=0+0

f(0)=0

So we want to find the slope of the line going through the points:

(-3,6) and (0,0)

Line them up-doesn't matter which point goes on top:

(-3,6)

(0,0)

---------Now subtract!

-3 , 6

The rise goes over the run so the slope is 6/-3 which simplifies to -2.
