The sales tax is $3.2 and total cost is $ 43.2

Solution:

Given, An item sells for 40$  

And sales tax on the item is 8 %  

We have to find what is the sales tax and total cost

Now, we know that, sales tax = 8% of selling price  

\begin{array}{l}{\text { Sales tax }=\frac{8}{100} \times \text { selling price }} \\\\ {\text { Sales tax }=\frac{8}{100} \times 40} \\\\ {\text { Sales tax }= 3.2}\end{array}

Now, sales tax = $ 3.2, then,

<em>Total final cost = selling price + sales tax </em>

Total cost = 40 + 3.2

Total cost = $ 43.2

Hence, sales tax and total cost are $3.2 and $43.2 respectively.

Answer:

(i) The name of the part of the circle, OQ is a radius

(ii) The radius of the sector QOR is 21 cm

Step-by-step explanation:

The given figure is a sector of the circle O

∵ Any sector of a circle formed from 2 radii and an arc

∴ OQ is a radius

(i) The name of the part of the circle, OQ is a radius

The rule of the length of an arc of a circle is L = \frac{\alpha }{360} × 2 π r, where

  • α is the angle of the sector
  • r is the radius of the circle

∵ The length of the arc QR is 22 cm

∴ L = 22

∵ The measure of the angle of the arc is 60°

∴ α = 60°

∵ π = \frac{22}{7}

→ Substitute them in the rule above

∵ 22 = \frac{60}{360} × 2 × \frac{22}{7} × r

∴ 22 = \frac{22}{21} r

→ Divide both sides by  \frac{22}{21}

∴ 21 = r

(ii) The radius of the sector QOR is 21 cm

Whats 1/5 - 1/7 please can you tell me how to work it out<br> thanks
Andrej [43]
Convert the fractions so they both have the same denominator (bottom part of the fraction)

1/5 = 7/35

This is because 5*7=35, so 1*7=7

1/7 = 5/35

This is because 7*5=35, so 1*5 =5

Then subtract the top numbers to get the answer:

\frac{7}{35}-\frac{5}{35} = \frac{2}{35}

Bogdan [553]

Answer: 7 hr

Step-by-step explanation:

Given

Distance between Emily and Kylie is 140\ \text{miles}

Speed of Emily v_e=12\ mph

Speed of Kylie v_k=8\ mph

Distance traveled by Emily \Rightarrow d_e=12t

Distance traveled by Kylie \Rightarrow d_k=8t

\Rightarrow 12t+8t=140\\\Rightarrow 20t=140\\\Rightarrow t=7\ hr

They will meet after 7 hour.
