Answer:

15.625

Step-by-step explanation:

(2.5)^3 = 2.5 · 2.5 · 2.5
2.5 · 2.5 · 2.5 = 6.25 · 2.5
6.25 · 2.5 = 15.625

Therefore, (2.5)^3 = 15.625.

Write and graph an equation in two variables that shows the relationship between the time t and the distance d traveled Moves 2

tiny-mole [99]

Answer:

the distance equation is

$d=\frac{2}{3}\times t$

Step-by-step explanation:

Let's assume

time in hours as 't'

distance traveled as 'd' meters

We are given

Moves 2 meters every 3 hours

So, firstly we find speed

$speed=\frac{2}{3}$

$k=\frac{2}{3}$

we know that

distance = (speed)*(time)

now, we can plug values

$d=k\times t$

now, we can plug value

$d=\frac{2}{3}\times t$

So, the distance equation is

$d=\frac{2}{3}\times t$

Talia tossed a penny many times. She got 20 heads and 80 tails. She said the experimental probability of getting heads was 20 80

iragen [17]

Answer:

the experimental probability is 1/5

Step-by-step explanation:

This is because one to calculate the experimental probability one has to divide the favorable events over the possible events, and those that Talia did were the favorable events divided the non-favorable events

20 heads and 80 tails

Faborable events = 20

Possible events = 20 + 80 = 100

20/100 = 1/5
