An ant walk about 3 inches per second how many miles per day could an ant travel if it walked without a break?

erastovalidia [21]

Answer:

Step-by-step explanation:

45/11 miles per day or ~4.091 miles per day

Step-by-step explanation:

3 inches per second

24 hours in a day

60 minutes in 1 hour

60 seconds in 1 minute

Amount of inches per minute: 3 x 60 = 180 inches

Amount of inches per hour: 180 x 60 = 10,800 inches

Amount of inches per day 10,800 x 24 = 259,200 inches

To find the number of feet that 259,200 inches is, divide by 12.

259,200/12 = 21,600 feet per day

To find the number of miles that 21,600 feet is, divide by 5280.

21,600/5280 = 45/11 = 4.09090909091 = ~ 4.091

So, an ant could walk 45/11 miles per day or ~4.091 miles per day if it walked without taking a break.

Please help me out please ..

Answer:

x = 466.7 ft

Step-by-step explanation:

The lower angle in the right triangle = 31° ( alternate angle )

Using the cosine ratio in the right triangle, with hypotenuse x

cos31° = $\frac{adjacent}{hypotenuse}$ = $\frac{400}{x}$

Multiply both sides by x

x × cos31° = 400 ( divide both sides by cos31° )

x = $\frac{400}{cos31}$ ≈ 466.7

I picked up 15 shells and my brother picked up 3 more shells than I did. How many shells did my brother pick up?

Artist 52 [7]

Let you = y
Let your brother = b

y = 15
b = y + 3

Plug in 15 for y

b = 15 + 3
b = 18

Your brother picked up 18 shells.

Hope this helps
