Answer:

The dimensions of the original picture is 3 inches by 5 inches .

Step-by-step explanation:

Let the length of original picture be x

Let the breadth of original picture be y

A scale drawing is made to enlarge a picture by using a scale factor of 3.

So, Length of enlarged picture = 3x

So, breadth of enlarged picture = 3y

Now we are given that . The enlarged picture is 9 inches by 15 inches.

So, 3x = 9                and       3y=15

      x = \frac{9}{3}                and       y=\frac{15}{3}

       x = 3                 and       y=5

Hence the dimensions of the original picture is 3 inches by 5 inches .

Amanda [17]

Answer:

The probability of making a correct random guess is 0.00053%.

Step-by-step explanation:

Since Clue is a board game in which you must deduce three details surrounding a murder, and in the original game of Clue, the guilty person can be chosen from 66 people, and there are 66 different possible weapons and 99 possible rooms, and at one point in the game, you have narrowed the possibilities down to 44 people, 55 weapons, and 77 rooms, to determine what is the probability of making a random guess of the guilty person, murder weapon, and location from your narrowed-down choices , and the guess being correct, the following calculation must be performed:

(1 / (44x55x77)) x 100 = X

(1 / 186,340) x 100 = X

0.0005366 = X

Therefore, the probability of making a correct random guess is 0.00053%.

A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 190 lb and each bo
vagabundo [1.1K]

Answer:

25 boxes.

Step-by-step explanation:

We have the inequality:

190 + 60x ≤ 1740  where  x = the number of boxes of books.

60x  ≤  1740 - 190

60x   ≤  1550

x ≤ 25.83.

PQ has endpoints P(-3,2) and Q(3,-2). Find the coordinates of the midpoint of PQ
hodyreva [135]

Answer:

(0,0)

Step-by-step explanation:

For this, you need to use the midpoint formula.

(-3) + 3                      2 + (-2)

--------------      ,       ----------------

     2                               2

This leads to:

-3 + 3 = 0 -> 0/2

x = 0

3 + (-3) = 0 -> 0/2

The answer is:

(0, 0)

In equilateral triangle RST, R has coordinates (0, 0) and T has coordinates of (2a, 0). Find the coordinates of S in terms of a.
FromTheMoon [43]
The x  coordinate of S will be 1/2 * 2a = a.
and since  the half triangle is 30-60-90 the y coordinate will be sqrt3 a

so S  is (a , sqrt3a)
