Which expression represents the shaded length of the number line below? Choose 1 answer: Choose 1 answer: (Choice A) A 34×32\dfr

Anit [1.1K]

Answer:

$Expression = \frac{2}{3} * \frac{5}{4}$

Step-by-step explanation:

<em>See attachment for number line</em>

From the attachment, we have the following details:

The first shade of blue covered 10 blocks

The second shade of blue covered 5 further blocks which totaled to 15

So, the fraction of the blue blocks is:

$Blue = \frac{10}{15}$

Divide fraction by 5/5

$Blue = \frac{10/5}{15/5}$

$Blue = \frac{2}{3}$

Also from the attachment:

The shaded block stopped at the fraction:

$Shaded = \frac{5}{4}$

So, the expression that represents this scenario is:

$Expression = Blue * Shaded$

$Expression = \frac{2}{3} * \frac{5}{4}$

The cost of a computer is $849. The store is offering a 20% discount, and then a sales tax of 6% is added after the discount. WH

Alex_Xolod [135]

Answer:

$719.95

Step-by-step explanation:

To find the purchase total, multiply the price by the percent paid and add the percent of tax.

The store offers a 20% discount. This means you pay 80% of the price. So the discounted price is 0.80(849) = 679.2.

Find the tax to be paid by multiplying 0.06(679.2) = 40.752.

Add the tax for the final total.

679.2 + 40.752 = 719.95
