If a shape has triple the dimensions of a similar shape then it has _______ the area *

IrinaK [193]

Answer:

9 times

Step-by-step explanation:

The best way to go about this is to give actual figures

Let us consider rectangular shape

Let us have a rectangle with dimensions 6 m by 12 m

The area will be 6 * 12 = 72 m^2

The shape having a similar dimension would have dimensions 12m by 36 m

So its area will be ;

18 * 36 = 648 m^2

So we finally proceed to make a division

Mathematically, that will be 648/72 = 9

So the area will be in the ratio of 1 to 9

Callie and Madison went to buy concert tickets for themselves and their five friends. The

nika2105 [10]

Answer:

They bought 0 ticket of closest section and 7 tickets of other section

Step-by-step explanation:

- Callie and Madison went to buy concert tickets for themselves and

their five friends

- That mean they are 7

- Tickets for the closest section were $45 each

- Tickets for other section were $30 each

- They ended up spending a total of $210

- Assume that they buy x tickets for closest section and y tickets for

the other section

∵ They want 7 tickets

∴ x + y = 7 ⇒ (1)

∵ The cost of the closest section ticket was $45

∵ The cost of the other section ticket was $30

∵ They spent $210 on them

∴ 45x + 30y = 210

- All terms have common factor 15, then divide them by 15

∴ 3x + 2y = 14 ⇒ (2)

* Now we have a system of equations to solve

- Multiply equation (1) by -2 to eliminate y

∴ -2x - 2y = -14 ⇒ (3)

- Add equations (2) and (3)

∴ x = 0

- substitute the value of x in equation (1) to find y

∴ 0 + y = 7

∴ y = 7

∵ x represents the number of tickets of the closest section and y

represents the number of tickets in the other section

∴ They bought 0 ticket of closest section and 7 tickets of other

section

Professor Liu gave the same quiz to the students in her morning class and in her afternoon class. The average (arithmetic mean)

natka813 [3]

Answer:

Afternoon class has more students.

Step-by-step explanation:

Let m be the number of students in the morning class and n be the number of students in the afternoon class.

The average score for the students in the morning class was 80, then the sum of their scores is $80m.$

The average score for the students in the afternoon class was 86, then the sum of their scores is $86n.$

The sum of the scores of both classes is

$80m+86n$

and the average score is

$\dfrac{80m+86n}{m+n}$

The average (arithmetic mean) score for the two classes combined was 84, then

$\dfrac{80m+86n}{m+n}=84\\ \\ 80m+86n=84m+84n\\ \\86n-84n=84m-80m\\ \\2n=4m\\ \\n=2m$

This means n is greater, so afternoon class has more students.
