Answer:

8 hours

Step-by-step explanation:

$216 → 12 hours

$1 → \frac{12}{216} hours

$144 → ( \frac{12}{216} *144) → 8 hours

First, you divide $216 by 12 hours to find the $ per hour.
216/12=18
This means you earn $18 per hour. Now, you divide $144 by 18 to find how many hours to get to $144.
The answer is 8 hours.

Suppose that there are two types of tickets to a show: advance and same-day. Advance tickets cost $30 and same-day tickets cost
Andre45 [30]

The number of advance tickets sold is 25 and same day tickets sold is 30.

Data Given;

  • Advance Ticket = $30
  • Same-day Ticket = $25
  • Total Ticket = $60
  • Total Cost of Ticket = $1625

<h3>System of Equations</h3>

Let the number of advance ticket be represented by x

Let the number of same-day ticket be represented by y

x + y = 60\\&#10;30x + 25y = 1625

From the system of equations above, we can easily pick any to start our calculation.

Using equation (i),

x + y = 60

x = 60 - y ...equation(iii)

Put equation (iii) into equation (ii)

30x + 25y = 1625\\&#10;x = 60 - y\\&#10;30(60 - y) + 25y = 1625\\&#10;1800 - 30y + 25y = 1625\\&#10;1800 -5y = 1625\\&#10;5y = 1800 - 1625\\&#10;5y = 175\\&#10;5y/5 = 175/5\\&#10;y = 35

Put the value of y into equation (i)

x+y = 60\\&#10;x + 35 = 60\\&#10;x = 60 - 35\\&#10;x = 25

From the calculation above, the number of advance tickets sold is 25 and same-day tickets is 30.

julian want to buy a new ipod that costs $220. he goes into a store and sees that it is on sale and has a 35% discount. he will
tigry1 [53]

Answer:

The final cost for him is;

\text{ \$154.44}

Explanation:

Given that the ipod costs $220;

C=\text{ \$220}

The store gives a 35% discount, which means he will only pay 65% of the original cost;

100\text{\%- 35\% = 65\%}

The store price is;

\begin{gathered} P=\text{ 65\% of \$220} \\ P=\frac{65}{100}\times\text{ \$220} \\ P=\text{ \$143} \end{gathered}

Also he will need to pay additional 8% sales tax on the discounted price P;

\begin{gathered} t=8\text{\% of P} \\ t=8\text{\% of \$143} \\ t=\frac{8}{100}\times\text{ \$143} \\ t=\text{ \$11.44} \end{gathered}

The final cost he need to pay is the sum of the discounted price and the sales tax;

\begin{gathered} F=P+t \\ F=\text{ \$143 + \$11.44} \\ F=\text{ \$154.44} \end{gathered}

Therefore, the final cost for him is;

\text{ \$154.44}

Is Figure B a scale copy of Figure A?
r-ruslan [8.4K]

Answer:

No.

Step-by-step explanation:

A scale copy would see that both the x and y amount would be scaled proportionally. In this case, the x goes across 5 for figure A, and does the same for Figure B. On the other hand, the scaling for y is 2 for figure A, while it is 5 for figure B.

If it is a scale copy then.

If Figure A have the scaling of: 3, 5, 5, x, then Figure B, if given one scale of 5, should have

3:5

5:8.33

5:8.33

x:(x * ~1.67)

Therefore, the scaling is off.
