Answer:

(i) 22.5

(ii) 7.2

Step-by-step explanation:

(i)

AB:PQ = 2:5 = 1:2.5

So PQ is 2.5 times longer than AB.

PQ=2.5AB=(2.5)9=22.5

(ii):

Since the triangles are similar, their sides are in ratio to each other. So if PQ was 2.5 times longer than AB, QR must also be 2.5 times longer than BC:

QR=2.5BC

BC=QR/2.5=18/2.5=7.2

In Las Vegas, Nevada, stores charge a 4.6% state sales tax and a 3.65% county sales tax. Keven is buying a handbag priced at 220
marshall27 [118]

Keven paid a sales tax of $ 18.15 for handbag purchase

<em><u>Solution:</u></em>

Given that stores charge a 4.6% state sales tax and a 3.65% county sales tax

Keven is buying a handbag priced at 220 before tax

To find: Sales tax paid by Keven

Sales tax amount = state sales tax amount + country sales tax amount

<em><u>Finding state sales tax amount:</u></em>

stores charge a 4.6% state sales tax which means 4.6 % of $ 220

state sales tax amount = 4.6 % of 220

\text{ state sales tax amount }= \frac{4.6}{100} \times 220

\text{ state sales tax amount }= 0.046 \times 220 = 10.12

Thus state sales tax amount is $ 10.12

<em><u>Finding country sales tax amount:</u></em>

Store charges a 3.65% of country sales tax which means 3.65% of $ 220

Country sales tax = 3.65 % of 220

\text{ Country sales tax } = \frac{3.65}{100} \times 220\\\\\text{ Country sales tax } = 0.0365 \times 220 = 8.03

Thus country sales tax = $ 8.03

<em><u>Now let us add both amount to get total tax paid by Keven</u></em>

Sales tax amount = state sales tax amount + country sales tax amount

Sales tax amount = $ 10.12 + $ 8.03 = $ 18.15

Therefore Keven paid a sales tax of $ 18.15 for handbag purchase
