the Kimball family. is going on a biking trip next they went to bike to Baltimore 27 1/2 mile away from their home they only wan

Juli2301 [7.4K]

Answer:

It takes 1.5 days for the Kimball family to get to Baltimore

Step-by-step explanation:

Given:

Total distance from the home to Baltimore = $27 \frac{1}{2}$

Distance they would travel on each day = $18 \frac{1}{8}$

To Find:

How many days it will take the Kimball family to reach Baltimore = ?

Solution:

Lets first convert mixed fraction into fraction

$27 \frac{1}{2}$ = $\frac{2 \times 27 + 1}{ 2}$ = $\frac{54+1}{2}$ = $\frac{55}{2}$

$18\frac{1}{8}$ = $\frac{18 \times 8 +1 }{8}$ = $\frac{144+1}{8}$ = $\frac{145}{8}$

Now,

In one day = $\frac{145}{8}$

In x day = $\frac{55}{2}$

By Cross multiplication

$\frac{55}{2} = x \times \frac{145}{8}$

$x = \frac{55}{2} \times \frac{8}{145}$

$x = \frac{220}{145}$

$x = \frac{44}{29}$

x = 1.517

x = 1. 5 days

Determine the intervals on which the function is increasing, decreasing, and constant. (3 points)

Cerrena [4.2K]

Answer:

A) increasing x > -1 ; decreasing x <-1

Step-by-step explanation:

We use the given graph to find the intervals where the function is increasing , decreasing and constant

We analyze the graph from the left

From the left the graph starts decreasing and it is decreasing till -1

From the point (-1,0) the graph changes direction and starts increasing

So we can say that the function is decreasing from -infinity to -1

and increasing from -1 to infinity

decreasing from -infinity to -1 means decreasing x <-1

increasing from -1 to infinity means increasing x > -1
