Answer:

Common ratio for the sequence is 3

Step-by-step explanation:

Given sequence is

5, 15, 45, 135,.....

To find out common ratio, divide the second number by the first number

$\frac{15}{5} =3$

$\frac{45}{15} =3$

$\frac{135}{45} =3$

we got 3 that is our common ratio 3

Common ratio for the sequence is 3

Sarah walks to school, 1.5 miles in 30 minutes. what is the snswer to this

nevsk [136]

Answer: 3 mi/h

Step-by-step explanation:

Here we have to find the speed $V$ at which Sarah walks to school, knowing the distance $d$ she has walked and the time $t$ she expends.

So, in this case we can use the following equation:

$V=\frac{d}{t}$

Where:

$d=1.5 mi$

$t=30 min \frac{1 h}{60 min}=0.5 h$

Solving:

$V=\frac{1.5 mi}{0.5 h}$

$V=3 mi/h$ This is Sarah's speed

Round 1.3981 to 3 significant figures

Scorpion4ik [409]

The answer would be 1.40. The 3 significant figure are 1.39 and it wants us to round so we look at the 8 in 1.3981 and since 8 > 5 we know to round up.
