Estimation is never an effective way to get the answer. But it's always an effective way to determine whether the answer you calculated is reasonable, or from orbit by way of left field.

The <em><u>correct answer</u></em> is:

Estimation is an effective way to determine an answer if we do not need an exact answer.

Explanation:

Estimation does not give us an exact answer. It gets us close to the exact answer, but it is not precise. This means we should use estimation to either check our work, or when we do not need a precise answer.

If a soccer team won 7 of its 13 games, what was their ratio of wins to losses? Assume that there were no tie games.

Yuri [45]

Answer:

Answer : A. 7 to 6

A soccer team won 7 of its 13 game

Total games played by soccer team = 13

Games won by the team = 7

Games lost = total games played - games won

So games lost = 13 - 7 = 6

Now we find the ratio of win to losses

game won = 7

games lost = 6

So the ratio of won to losses is 7 to 6

I thought of a number, I added 1 3 4 to it, then I multiplied the result by 2 2 11 and I got 8. What was my number?

Valentin [98]

Given:

In a number, adding $1\dfrac{3}{4}$ , then multiplying the result by $2\dfrac{2}{11}$ we get 8.

To find:

The unknown number.

Solution:

Let the unknown number be x.

According to the question,

$(x+1\dfrac{3}{4})\times 2\dfrac{2}{11}=8$

$(x+\dfrac{1\times 4+3}{4})\times \dfrac{2\times 11+2}{11}=8$

$(x+\dfrac{4+3}{4})\times \dfrac{22+2}{11}=8$

$(x+\dfrac{7}{4})\times \dfrac{24}{11}=8$

Multiply both sides by $\dfrac{11}{24}$ .

$x+\dfrac{7}{4}=8\times \dfrac{11}{24}$

$x+\dfrac{7}{4}=\dfrac{11}{3}$

Subtract $\dfrac{7}{4}$ from both sides.

$x=\dfrac{11}{3}-\dfrac{7}{4}$

$x=\dfrac{44-21}{12}$

$x=\dfrac{23}{12}$

$x=1\dfrac{11}{12}$

Therefore, the required number is $1\dfrac{11}{12}$ .

A 6-pack of toilet paper costs $5.40. A 12-pack of toilet paper costs $11. Which package offers the best price per roll?

igomit [66]

Answer: 6-pack.

Step-by-step explanation:

assuming there’s no tax, the 6-pack would offer the best price per roll.

for 12 rolls w/ the 6 pack it’d be 10.80 which divided by 12 is .9(0)a roll. Where as the 12 for 11 is roughly .91 . So the 6-pack is a better offer.
