<h2>Hello!</h2>

The answer is:

\frac{14}{12}=\frac{7}{12}*2\\\\\\\frac{21}{12}=\frac{7}{12}*3\\\\\\\\\frac{28}{12}=\frac{7}{12}*4\\\\\\\\\frac{35}{12}=\frac{7}{12}*5

<h2>Why?</h2>

A multiple of a number is the repeated sum of itself, for example:

Multiple of the number 1 are: 1, 2, 3, 4, 5 and so...

Multiple of the number 3 are: 3, 6, 9, 12, 15 and so...

From the example we have:

Multiple of the number 3 are: Itself, (3+3), (3+3+3), (3+3+3+3), (3+3+3+3+3) and so...

So,

Multiple of \frac{7}{12} are:

\frac{14}{12}=\frac{7}{12}*2=\frac{7}{12}+\frac{7}{12}\\\\\\\frac{21}{12}=\frac{7}{12}*3=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}\\\\\\\\\frac{28}{12}=\frac{7}{12}*4=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}\\\\\\\\\frac{35}{12}=\frac{7}{12}*5=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}

Have a nice day!

A fertilizer covers 3 4 square foot in 1 2 hour. The unit rate is square feet per hour.
Alenkasestr [34]

Answer:

2\frac{5}{6} square foot per hour

Step-by-step explanation:

The total area covered = 34 square foot

Time taken = 12 hours

This implies that it takes 12 hours to cover 34 square foot.

Using proportionality,

12 hours ---------------------------------------> 34 square foot

Dividing both sides by 12

\frac{12}{12} hours ---------------------------> \frac{34}{12} square foot

1 hour ---------------------------------------> 2\frac{5}{6} square foot per hour

The unit rate in square feet per hour is 2\frac{5}{6} square foot per hour

Martin bought a flower vase from a florist. The box in which the vase was packed was shaped like a rectangular prism.
34kurt

Answer:

the answer is C: 1932 sq. cm

Step-by-step explanation:

You want to break down the sections (which is double for each)

there are 6 rectangles but you will only need to calculate for 3

1st rectangle

a = (25) (12)

a = 300 sq. cm

**then multiply by 2 = 600 sq. cm**

2nd rectangle

a = (12) (18)

a = 216 sq. cm

then 216 * 2 = 432 sq. cm

3rd rectangle

a = (25) (18)

a = 450 sq. cm

then 450 * 2 = 900 sq. cm

Total Surface Area

SA = 600 sq. cm + 432 sq. cm + 900 sq. cm

SA = 1932 sq. cm

The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults. On a certain day
GaryK [48]

Answer:

Number of child tickets =  800

Number of adult tickets = 330

Step-by-step explanation:

Let c = number of child tickets

and  a= the number of adult tickets.

We are given:

The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults.

On a certain day, 1,130 enter the festival and 2, 520 is collected.

Making equations:

c+a=1130 (because total people entered are 1130, so adding number of adult and child tickets will give us total number of people)

1.50c+4.00a=2520  (because total money collected is 2520, so adding coat of adult and child tickets will give us total money)

Now, solving these equations simultaneously, we can find values of x and y

Let:

c+a=1130--eq(1)\\1.50c+4.00a=2520--eq(2)

From equation 1 find value of c and put it in eq(2)

c+a=1130\\c=1130-a

Putting value of c in eq(2)

1.50c+4.00a=2520\\Put\:c=1130-a\\1.5(1130-a)+4a=2520\\1695-1.5a+4a=2520\\-1.5a+4a=2520-1695\\2.5a=825\\a=\frac{825}{2.5}\\a=330

So, we get value of a = 330

Now, punting value of a in eq(1) to get value of c

c+a=1130\\c+330=1130\\c=1130-330\\c=800

So, we get value of c = 800

Therefore:

Number of child tickets = c= 800

Number of adult tickets = a = 330
