let's first convert the mixed fractions to "improper" and then sum them up.


\bf \stackrel{mixed}{2\frac{2}{3}}\implies \cfrac{2\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{8}{3}} \\\\\\ \stackrel{mixed}{1\frac{1}{2}}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}}\\\\ -------------------------------\\\\ \cfrac{8}{3}+\cfrac{3}{2}\quad \stackrel{LCD~of~6}{\implies }\quad \cfrac{(2)8+(3)3}{6}\implies \cfrac{16+9}{6}\implies \cfrac{25}{6}\implies 4\frac{1}{6}

The speed of light is 3 x 105 kilometers per second. What is that in standard form?
spayn [35]

Answer:

speed of light is 3 x 10^{8} meters per second.

Step-by-step explanation:

Given : The speed of light is 3 x 10^{5} kilometers per second.

To find :  What is that in standard form.

Solution : We have given 3 x 10^{5} kilometers per second.

First we convert it in to meter per sec.

We can write  

3 x 10^{5} = 300000 kilometer per second .

We know that 1 km = 1000 meter.

Then 300000000 meter per second

Now,   3 x 10^{8} meter per second.

Therefore,  speed of light is 3 x 10^{8} meters per second.

2 The points (-15, -3) and (-7, -1) both
hammer [34]

Answer:

The rate of change of f(x) with respect to x is 1/4

Step-by-step explanation:

What this question simply ask is to find the slope of the line that passes through the two points

to find this, we use the slope equation

we have this as;

m= (y2-y1)/(x2-x1)

(x1,y1) = ((-15,-3)

(x2,y2) = (-7,-1)

m = (-1 + 3)/(-7 + 15) = 2/8 = 1/4
