Answer:

49,000

Step-by-step explanation:

The divisor is 4.084. When it is rounded to the nearest whole number, it is 4.

Then the division problem becomes ...

196,900/4 ≈ 49,000 . . . . . . showing just 2 significant digits for the estimate

The point of an estimate is to obtain an approximate answer that is within a few percent of the actual answer. Here, rounding 4.084 to 4.000 gives an error on the order of .084/4 ≈ 2.1%. Because we're using a smaller divisor, the value we obtain for our estimate will be too large by about that amount.

Often, an estimate that has 1 or 2 significant digits is "close enough" for the purpose. Because a change in our estimated value of 1 in the least significant digit is a change of about 2%, we judge this estimate to be "close enough", given the rounding we did to start. Keeping 3 significant digits in our estimate would claim an accuracy that it does not have.

Answer:

m + m/4 + 3m/2 > 22
m > 8 . . . . m restricted to multiples of 4, perhaps

Step-by-step explanation:

Let m represent the number of articles Mustafa has written. Then the total number of articles written must satisfy the inequality ...

m +m/4 +3m/2 > 22

This has solution ...

(11/4)m > 22

m > (4/11)22

m > 8 . . . . . . . . the solution to the inequality

If all the numbers are integers, and the ratios are exact, then we must have m be a multiple of 4 (that is, 4 times the number of articles Heloise wrote).

The solution set will be ...

m ∈ {12, 16, 20, 24, ...} (multiples of 4 greater than 8)

Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles hold.

g100num [7]

Step-by-step explanation:

Part 1

To find out the amount of water ten big water bottles can hold, we have to find out how much water is in each water bottle. To do this, we divide the amount we are looking for by the number of items.

8 ÷ 4 = 2

Part 1 answer: Each water bottle can hold 2 gallons of water.

Part 2

Now that we know the amount of water in each water bottle, we can find out how much water 10 water bottles can hold. To do so, we multiply our previous answer, 2, by the number of items (10).

2 • 10 = 20

Part 2 answer: 10 water bottles can hold 20 gallons of water.

Our final answer: 20 gallons

I actually have 5 questions on the same thing, just different setups. But how would I go about solving them? .-.

Ivanshal [37]

1) 2p = -2.
 4p [ y - k ] = [ x - h) ]² --- > - 4 [ y + 5 ] = [ x + 5 ]²
2) 4p * (y - k) = (x - h)^2 

(h , k) is the vertex 

The vertex is halfway between the focus and the directrix (when they're at their closest) 
p is that distance 

2 - 1 = 1 
4p = 1 
p = 1/4 

(1/4) * (y - k) = (x - h)^2 
y - k = 4 * (x - h)^2 

The vertex is at (6 , 3/2), since that's midway between (6 , 1) and (6 , 2) 

y - 3/2 = 4 * (x - 6)^2 
y = (3/2) + 4 * (x - 6)^2

4) f(x) = (-1/16)*(x²)

5) f(x) = −1/4 x2 − x + 5
