It cost $36.75 for 3 tickets to visit the science center. It cost $51 for tickets for 4 tickets to visit the zoo. Which attracti

jonny [76]

Answer:

It would cost more to go to the zoo by $6

Step-by-step explanation:

The total amount that each attraction costs can be given by;

<em>Science center</em>

Total cost at the science center=cost per ticket×number of tickets

where;

Total cost at the science center=$36.75

Cost per ticket=c

Number of tickets=3 tickets

Substituting;

36.75=c×3

c=(36.75/3)=12.25 per ticket to go to the science ticket

For 12 students, total cost at the science center=(12.25×12)=$147

Total cost at the zoo=cost per ticket×number of tickets

where;

Total cost at the zoo=$51

Cost per ticket=d

Number of tickets=4 tickets

Substituting;

51=d×4

d=(51/4)=12.75 per ticket to go to the zoo

For 12 students, total cost at the zoo=(12×12.75)=$153

Total zoo cost-Total science center cost=(153-147)=$6

It would cost more to go to the zoo by $6

Consider this scaled figure of a swimming pool. The dimensions of the original pool are 24 feet wide by 36 feet long. A rectangl

kozerog [31]

The scale factor used for scaling the actual rectangular pool was 4/15 and the length of the scaled rectangle is 9.6 feet.

<h3>How to calculate the scale factor?</h3>

Suppose the initial measurement of a figure was x units.

And let the figure is scaled and new measurement is of y units.

Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.

Then we have:

$s \times x = y\\s = \dfrac{y}{x}$

Thus, scale factor is the ratio of the new measurement to the old measurement.

For this case, we're specified that:

Dimensions of the original pool = 24 feet wide by 36 feet long

The scaled rectangle's dimension: 6.4 feet width and L feet length (we assume the length be L units).

So, in scale drawing, 24 feet was converted to 6.4 feet. Let the scale factor be 's', then:

$6.4 = s \times 24\\\\s = \dfrac{6.4}{24} = \dfrac{4}{15}$

Thus, since length is also scaled by same factor(as the whole figure is scaled by constant scale factor assumingly), we get:

Scaled length = s times original length

$L = \dfrac{4}{15} \times 36 = 9.6 \: \rm feet$

Thus, the scale factor used for scaling the actual rectangular pool was 4/15 and the length of the scaled rectangle is 9.6 feet.

Craig has $1850 dollars in a bank account that he uses to make automatic payments of $400.73 on his car loan. If Craig stops mak

Ivenika [448]

Given:

Amount in the bank account = $1850

Monthly payment of can loan = $400.73

To find:

When would automatic payments make the value of the account zero?

Solution:

Craig stops making deposits to that account. So, amount $1850 in the bank account is used to make monthly payment of can loan.

On dividing the amount by monthly payment, we get

$\dfrac{1850}{400.73}=4.61657$

It means, the amount is sufficient for 4 payment but for the 5th payment the amount is not sufficient.

Therefore, the 5th automatic payments make the value of the account zero.
