Answer:

Step-by-step explanation:

You would have know to how much accuracy you want to know. Estimates are about ball parking a number into some other idea about an easy way to understand what a number represents. 5,000 might be a good estimation for a distance that you're going to walk, if the exact distance is 5,004. You get a pretty good idea of how far , time wise, energy required ect ect.. when you say 5,000 So estimation is really about making the numbers easier to use and understand. Numbers are "abstract" they only represent ideas.

Faucet A flows at a rate of 100 liters per 5 minutes and Faucet B flows at a rate of 100 liters per 4 minutes into an empty pool

Dmitriy789 [7]

Answer:

It will take both faucets 200 minutes to fill a pool with 9,000 liters of water

Step-by-step explanation:

Here, we want to know the time it will take for both faucets to fill a pool with 9,000 liters of water

What we need here is to have a joint rate for both faucets;

For the first faucet, we have a rate of 100 liters per 5 minutes so this means in a minute;

100/5 = 20 liters per minute

For the second faucet, the per minute rate will be 100/4 = 25 liters per minute

So therefore, the joint rate will be;

25 liters per minute + 20 liters per minute = 45 liters per minute

So the time needed to fill 9,000 liters of water in a pool will be ;

9000 liters/ 45 liters per minute = 200 minutes

Can someone please help me with this, I'm having trouble

dexar [7]

This is another one for my "impossible math question" file. All of the answer choices are wrong. (None applies.)

According to the problem statement, the length you have marked "x" in the diagram is 15 inches. If the side length of one of the pavers is "s", then the Pythagorean theorem tells us
s² + (2s)² = 15²
5s² = 225
s² = 225/5 = 45 . . . . . . the area of one square is 45 in² (not 225 in²)

Then
s = √45 = 3√5 . . . . . . . the length of one side is not 5√3
so the perimeter is
p = 4s = 4·3√5 in = 12√5 in ≈ 26.83 in . . . . not 75 inches.

The area of the 6-block L-shaped path is
total area = 6s² = 6·45 in² = 270 in² . . . . not 450 in²

And the total perimeter is 14 sides, so is
total perimeter = 14s = 14·3√5 in = 42√5 in . . . . not 60√3 in

In cases like this where the answer key is incorrect, you might try asking your teacher show the class how to work the problem.

Why does 3^4 x 3^6 simplify to 3^10 instead of 9^10

k0ka [10]

Answer:

3^10

Step-by-step explanation:

Because the rules of index

3^4 = 3*3*3*3

3^6 = 3*3*3*3*3*3

(3^4)(3^6)=

3*3*3*3*3*3*3*3*3*3 = 3^10
