Option B model shows the percent of beads that are blue.

Solution:

Fraction of beads blue = \frac{4}{20}

To convert it into percent multiply the fraction by 100.

$\text {Percent of} \ \frac{4}{20}=\frac{4}{20}\times 100\%

                     $=\frac{4\times 100}{20} \%

Cancel the common factors, we get

                    = 20%

                    $=\frac{20}{100}

This means total number of boxes 100 and shaded in blue color 20.

Therefore option 2 represents \frac{20}{100}.

Hence option B model shows the percent of beads that are blue.

Alba worked for 6 hr 45 min at $7.90 per hour. What numbers could she use to estimate how much money she earned? Estimate the am
Svetradugi [14.3K]

Answer:

  • $52
  • this estimate is a little low

Explanation:

a) I might choose 6 1/2 hours and $8 per hour, so the estimated earnings would be ...

  6(8) +(1/2)(8) = 52 dollars . . . . estimated earnings

These values are purposely chosen so that one is a little high and the other is a little low, hopefully producing a closer estimate than if both numbers were high (as 7 hours, $8, for example).

__

b) Using 800 instead of 790 means the pay estimate is about 1/80 = 1.25% high.

Using 6 1/2 instead of 6 3/4 means the hours estimate is about 1/27 ≈ 3.7% low.

So, we expect the product of these values to be slightly low, perhaps by about 2.5%.

_____

<em>Comment on estimating</em>

If you can estimate the error in the estimate with some reasonable accuracy, you can use that to adjust the estimate to a pretty close value.

Student programs = 12,000 x 0.5 = 6000
teacher programs = 12000 x 0.23 = 2760
school supplies = 12000 x 0.17 = 2040
technologies = 12000 x 0.10 = 1200

1. 6000 - 2040 = 3960  this is TRUE
2. 6000 - 1200 = 4800 this is FALSE
3. 6000 + 2760 = 8760 ( approximately 8800)  this is TRUE
4. teacher programs = 2760 this is FALSE
5. FASLE
