If a block is moving at a constant speed of 4 m/a and travels for 15.43 s, what is the distance did it travel in km, show all wo

Alik [6]

Answer: It traveled 0.06172 km.

Step-by-step explanation:

Given: Speed of block = 4 m/s

Time taken by block = 15.43 s

To calculate: Distance covered by it in km.

We know that,

$Distance = speed \times time$

So distance covered by block = $4\times15.43$

= $61.72\ m$

Since 1 kilometer = 1000 meters.

So,

$61.72\ m=\dfrac{61.72}{1000}\ km=0.06172\ km$

Hence, it traveled 0.06172 km.

1. If you wish to calculate the interest on an investment with an interest rate

maksim [4K]

<h3>Answer: Choice D) 0.0285</h3>

=========================================

Explanation:

You move the decimal point two spots to the left to go from 2.85% to 0.0285

Or you can think of it like this:

2.85% = (2.85)/100 = 0.0285

since "percent" means "per 100"

Help please thank uuuu

zaharov [31]

Answer:

B. x = 7; AB = 9, AC = 12

Step-by-step explanation:

12/4 = (x + 2)/(x - 4) (similar triangles theorem)

3 = (x + 2)/(x - 4)

Cross multiply

3(x - 4) = (x + 2)

3x - 12 = x + 2

Collect like terms

3x - x = 12 + 2

2x = 14

x = 14/2

x = 7

✔️AB = x + 2 = 7 + 2

AB = 9

✔️AC = (x + 2) + (x - 4) = (7 + 2) + (7 - 4)

AC = 9 + 3

AC = 12
