WHAT IS THE CORRECT SCALE FACTOR?

Mathematics
1 answer:
topjm [15]3 years ago
3 0

Answer:

3/7

Step-by-step explanation:

To find the scale factor we have to compare the initial points to the final points, we can do this by observing only one corner of the triangle, as it will apply to the entire triangle.

<u><em>Let's look at C and C'</em></u>

The coordinates of C are (7,-7)

The coordinates of C' are (3,-3)

<u><em>To make things simpler let's find the relationship between our x-coordinates, then test it on our y-coordinates</em></u>

We essentially have to find what 7 is multiplied by to get 3, we'll make an equation

7x=3

Solve for x by dividing both sides by 7

x=3/7     <------- This shows that our scale factor in this case is 3/7

<em><u>Now we will test this on our y-coordinates</u></em>

-7(3/7)=-3

\frac{-7(3)}{7}=-3?

The 7's on the top and bottom simplify to -1

-1(3)=-3?

-3=-3 <------- This is true! So we know this is our scale factor for the entire triangle

Hope I could help!

Thirty elves would like to build a skating ring so they can all use it at the same time. Santa tells them, they need at least 40
Delicious77 [7]

Answer:

The Possible dimension of the ring could be;

20 ft × 60 ft

25 ft × 48 ft

30 ft × 40 ft

60 ft × 20 ft

48 ft × 25 ft

40 ft × 30 ft

Step-by-step explanation:

Given:

Number of skaters = 30

Area for each skater = 40 sq ft

We need to find the dimension of rectangular ring the are going to build.

Now we know that they building the skating ring such that they all can use at same time.

Hence if the all use at same time then we will find the total area first.

Total area can be calculated by multiplying Number of skaters with area required for each skaters.

Framing the equation we get;

Total area = 30\times 40 = 1200 \ ft^2

Hence The total area of the rectangular ring would be 1200 sq. ft.

Now we know that Total area is equal to product of length and width.

length\times width =1200ft^2

1200 can be written as = 20 × 60, 25 × 48, 30 × 40,60 × 20,48 × 25,40 × 30

Hence the Possible dimension of the ring could be;

20 ft × 60 ft

25 ft × 48 ft

30 ft × 40 ft

60 ft × 20 ft

48 ft × 25 ft

40 ft × 30 ft
