Why does dividing 5 by a decimal less than 1 give a quotient greater than 5

5 x 0.2 = 25

Or to put it a different way

25 / 0.2 = 5

Dividing something by a number greater than 1 gives you a smaller number
Dividing something by 1 gives the same number
Dividing something a number smaller than 1 gives you a larger number

This is because when you divide any number by 1, it is itself. when you divide a number by anything by anything more than 1, the answer is less than the starting number. ex: 5/1 =5. 5/2 =2.5. So, because of reasoning and what the calculator will tell is that if you divide by anything less than one, it has to be greater. For example 5/.5=10. this can be easy if you know porportions. what you do with those is try to make the denominator an easier number to understand or the same as another fraction/mixed number. So, to take 5/.5=10, you can multiply the top and bottom numbers by 2 to get 10/1, which we know for a fact, will always equal 10.

Find the equation of the exponential function represented by the table below
Gennadij [26K]

Answer:

y = 3^(1 + x)

Step-by-step explanation:

Notice that each time x increases by 1, y increases by a factor of 3.

Thus, the required equation  has the form y = 3^x.

Check:  If x = 0, do we get 3?  No.  Therefore we must modify the exponent:

y = 3^(1 + x)

Check:  If x = 0, do we get 3?  3^(1 + 0) = 3 (correct)

If x = 2, do we get 27?  3(1 + 2) = 3^3 + 27 (correct)

Emilio bought an ant farm that had 15 ants in it already. He read somewhere that
Nina [5.8K]

The number of ants in his farm after 12 weeks is 218.

Step-by-step explanation:

Step 1:

It is given that there are 15 ants initially and the ant population increases by 25% each week.

This is an exponential rate of increase that can be modeled by the following equation:

Number of ants after n weeks = Initial number of ants * (1 + rate of increase) ^{n}

Step 2:

Rate of increase = 25% = 25 / 100 = 0.25

Number of weeks = 12

Number of ants  after 12 weeks = 15* (1 + 0.25 )^{12} = 218.27 (rounded off to 218)

Step 3:

Answer:

The number of ants in his farm after 12 weeks is 218.

vfiekz [6]

Answer:

4

Step-by-step explanation:

Step 1:

6x - 8 = 4x        Equation

Step 2:

6x = 4x + 8        Add 8 on both sides

Step 3:

2x = 8     Subtract 4x on both sides

Step 4:

x = 8 ÷ 2      Divide

Answer:

x = 4
