Ruth found 37 tickets for $7. Please help Ruth by figuring out the ratio. (round to 2 decimal places)

Amanda [17]

Answer:

Ratio of ticket to its price is 1 : 0.189.

Step-by-step explanation:

Here, the cost of 37 tickets = $7

Let us find the unit cost of the ticket.

$\textrm{Unit Price } = \frac{\textrm{Total Price of n units}}{\textrm{n}}$

$\implies U = \frac{7}{37}=0.189$

So, the unit price of each ticket = $0.189

Now, ratio of Each Ticket: Unit Price = 1 : 0.189

Hence, the ratio of ticket to its price is 1 : 0.189.

Douglas bought a $20 game card at a

satela [25.4K]

Answer:

Douglas can race the go-karts at least 3 times.

Step-by-step explanation:

Given that:

Worth of game card = $20

Cost of go-kart = $3.50 each time

Amount Douglas wants to left = $7.75

Let,

x be the times Douglas can ride go-kart.

20 - 3.50x ≤ 7.75

-3.50x ≤ 7.75 - 20

-3.50x ≤ -12.25

3.50x ≤ 12.25

Dividing both sides by 3.50

$\frac{3.50x}{3.50}\leq \frac{12.25}{3.50}\\x\leq 3.5$

Hence,

Douglas can race the go-karts at least 3 times.

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, David has s

jasenka [17]

Answer:

The answer in interval notation is ( 73 , 100 )

Step-by-step explanation:

If we call x and y the lower and upper values for David to get an average of 80 and 89 respectively, we can calculate these two values solving a pair of equations:

(81 + 92 + 74 + x ) / 4 = 80 ⇒ (247 + x )/4 = 80

247 + x = 320 ⇒ x = 320 - 247

x = 73

And

(81 + 92 + 74 + y ) / 4 = 89 ⇒ ( 247 + y ) / 4 = 89

247 + y = 356

y = 356 - 247

y = 109

But tests are a 100-point test

Then the answer in interval notation is ( 73 , 100 )

The perimeter of a rectangle is 215 feet. The short sides are each 24 feet long, but the lengths of the long sides are unknown.

Nataly_w [17]

Answer:

2 ( 24 ) + 2 a = 215

Step-by-step explanation:

Perimeter of the rectangle is 215 feet, the short sides are 24 feet long and we need to work out the long sides (we will call a long side 'a') so,

24 + 24 + a + a = 215
