Find the percentage of vacationers from<br> question 10 who spent between $1500<br> and $2000.

mars1129 [50]

Answer:

The percentage change of vacationers is 33.3 %

Step-by-step explanation:

Given as :

The old value of the vacationers = $ 1500

The new value of the vacationers = $ 2000

Let the percentage variation = x %

Or, x % increase = $\dfrac{\tyextrm new value - \textrm old value}{\textrm old value}$ × 100

Or, x % increase = $\dfrac{\tyextrm $ 2000 - \textrm $ 1500}{\textrm $ 1500}$ × 100

Or, x % increase = $\frac{500}{1500}$ × 100

Or, x % increase = $\frac{1}{3}$ × 100

Or, x % increase = $\frac{100}{3}$

∴ x = 33.3 %

So, The percentage increase change is 33.3 %

Hence The percentage change of vacationers is 33.3 % Answer

Milene é doceira e a seguir está uma representação dos bombons que ela fez no dia. Do total dos bombons que fez 2/3 são de coco.

Paha777 [63]

Answer:

16 bombons de coco

4. DECK is a parallelogram. Find the values of x and y.

Darya [45]

Answer:

The value of x = 5 and y = 2.

Step-by-step explanation:

Here, given DECK is a parallelogram.

Also, KT = 2x + y , DT = x + 2y , TE = 12 and TC = 9

Now, in parallelogram:

DIAGONALS IN A PARALLELOGRAM BISECT EACH OTHER

Also, in the parallelogram DECK,

Sides DC and KE are two diagonals.

⇒ T is the mid point of AC and KE.

⇒ KT = TE and DT = TC ( as diagonals are bisected)

⇒ 2 x + y = 12 and x + 2y = 9

So here, the set of two equations are:

2 x + y = 12 ....... (1)

x + 2 y = 9 ....... (2)

Multiply (2) with -2 and add with (1), we get:

2 x + y - 2 x - 4 y = 12 - 18

or, - 3 y = - 6

or, y = 2

If y = 2, then x + 2 (2) = 9 or, x = 5

Hence the values of x = 5, y = 2
