Answer:

1 day equals 400 times 10 = 4,000 meters so which = 4 kilometers

1 day = 4,000 m = 4 km

2nd day = 8,000 m = 8 km

3rd day = 12,000 m = 12 km

Answer: It will take 3 days.

Step-by-step explanation:

1 km = 1000m

12 km = 12,000m

10 * 400m = 4000m

12,000m / 1000m = 3

So, It will take 3 Days.

I hope I helped you with this I-Ready. Have a Great day!

Factor this expression completely.<br> 36y2 - 1

shtirl [24]

Answer:

(6y - 1)(6y + 1)

Step-by-step explanation:

To factorize completely, we may adopt the difference of 2 squares approach. The theory states that difference of two square is the product of the difference of the number and the sum of the numbers.

Such that

a² - b² = (a - b) (a + b)

Hence 36y² - 1

= 6²y² - 1²

= (6y)² - 1²

= (6y - 1)(6y + 1)

A number m is more than -7 2/3 or at most -10

frutty [35]

This situation is represented by the following disjoint inequality:

$m > -\frac{23}{3} \cup m \leq -10$

---------------------------

The format of a <u>disjoint inequality</u> is:

$x > a \cup x \leq b$

Which is read as: x is more than a or at most b.

---------------------------

In this question, we have number m more than $-7\frac{2}{3} = -7 - \frac{2}{3} = -\frac{21}{3} - \frac{2}{3} = -\frac{23}{3}$ and at most -10, thus, the disjoint inequality that represents this situation is:
