A tortoise is walking in the desert. It walks at a speed of 7 meters per minute for 8.96 meters. For how many minutes does it walk?

1.28 minutes

Step-by-step explanation:

Given data

Speed= 7 meters per minute

Distance= 8.96 meters

We know that the expression for the Speed, Distance, and time is given as

Speed= Distance/Time

TIme= Distance/Speed

Substitute

Time= 8.96/7

Time= 1.28 minutes

d

step-by-step explanation:

d

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
