Quadrilateral ABCD is dilated by a scale factor of 1 over 3 centered around (1, 2). Which statement is true about the dilation?
Sonbull [250]

<em>Note: Since you missed to add the figure. So, after a little research I am kind of able to find the figure and hence, assuming it as a reference. Hence, I am attaching the figure and solution of that figure is also visible in the same figure.</em> Please check the attached figure (a)

Answer:

Segment B'D' will be parallel to segment BD and will be shorter than segment BD. Please see the attached figure (a) for better understanding.

Step-by-step explanation:

As we know that there are certain rules when a quadrilateral is dilated by a certain scale centered around a certain point.

So,

Let suppose P(a, b) is the point.

The dilation rule by a scale factor of 1 over 3 or (1/3) centered around (1, 2) is

P(a, b) → P(\frac{x+2}{3}, \frac{y+4}{3})

Hence,

            A(1, 2) → A'(1, 2)

            B(2, 3) → B'(4/3, 7/3)

            C(4, 2) → C'(2, 2)

             D(2, 1) → D'(4/3, 5/3)

The attached figure show that if we draw the all these points in the coordinate plan i.e. A(1, 2), B(2, 3), C(4, 2), D(2, 1) and A'(1, 2), B'(4/3, 7/3), C'(2, 2), D'(4/3, 5/3), we can determine that Segment B'D' will be parallel to segment BD and will be shorter than segment BD.

Jonathan fills 2/5 of a toffe box in 15 seconds. How many boxes can he fill in 10 minutes?
Zina [86]

Answer:

16 boxes in 10 minutes

Step-by-step explanation:

2/5 = 15 sec

15 ÷ 2=7.5              1/5 = 7.5 seconds

7.5 × 5 = 37.5            37.5 = 1 box

60 × 10 = 600 secs

600 ÷ 37.5 = 16

16 boxes of toffee were made in 10 minutes

I have a problem -3x-7=-13. When isolating x I divide x by -3 then divide -13 by -3 correct?
rosijanka [135]

Hello!

no, that is not the correct way to isolate x. you were somewhat on the right track however.

here's the correct way:

add 7 to both sides to get -3x = -6

then divide both sides by -3 to get x = 2

I hope this helps, and have a nice day!

Three ounces of broiled ground beef contains 245 calories. Is this the number of calories directly or inversely proportional to
aalyn [17]

Answer:

The number of calories are directly proportional to the number of ounces.

Step-by-step explanation:

We can relate these values as:

Let x be the calories in 4 ounces of broiled hamburger.

\frac{3}{245} =\frac{4}{x}

=> 3x=4\times245

=> 3x=980

Dividing by 3 on both sides;

x = 327 approx

We can see that 4 ounces contain 327 calories.

Per ounce will have 327/4=81.75 calories.

As the quantity of hamburger increases, the calories count also increases.
