How does a scale factor change the size of a figure?

Mathematics

The scale factor can change how big or small a figure is, though it will still be similar. For example, a triangle with two sides measuring 3 & 3 (isosceles) are scaled in a factor of 6 (becoming larger).

3 x 6 = 18

The new triangle will have the sides measuring 18. Even though the triangles are not congruent, they are similar.

Hello!

The scale factor shows how much a figure is dilated. For example, if you have a square that has an area of 4, and it is dilated by a scale factor of 2, its area will become 8, or with a scale factor of 1/2, it will become 2/

Maggie has 4 3/5 of icing to decorate cakes for a bake sale. Each container will cover 20 1/4 in2. How many square inches will i
ExtremeBDS [4]

Answer:

93\frac{3}{20} \ square \ inches.

Step-by-step explanation:

Given:

Maggie has 4 3/5 container of icing to decorate cakes for a bake sale.

Each container will cover 20 1/4 square inches.

Question asked:

How many square inches will it cover if she uses all of her icing ?

Solution:

Total number of container Maggie has = 4\frac{3}{5}

Each container will cover = 20\frac{1}{4} square inches.

Now, we can find easily that how many square inches it will cover by using all of her icing by unitary method:

Each container will cover = 20\frac{1}{4}

4\frac{3}{5} container will cover = 20\frac{1}{4}\times4\frac{3}{5} =\frac{20\times4+1}{4} \times\frac{5\times4+3}{5} \

                                                        =\frac{81}{4} \times\frac{23}{5} =\frac{1863}{20} =93\frac{3}{20}\ square\ inches

Thus,  it will cover 93\frac{3}{20} \ square \ inches ,if she uses all of her icing.

A boat that is 2 miles offshore from a lighthouse is moving parallel to the coast. The light on the lighthouse is turning at the
Papessa [141]

Answer:

speed of light movement when boat is 1 mile from light house is 0.029  miles/sec

Step-by-step explanation:

Given data:

distance of boat from light house is 2 miles

rate of turning of light is 100 degree per minute

w = 100 degree/min

w = 100 \times \frac{\pi}{180} rad/min

w = 1.745 rad/min

w = 0.0290 rad/sec

speed of movement of light v = w\times r

v = 0.029 \times 1 = 0.029 mile/sec

thus speed of light movement when boat is 1 mile from light house is 0.029  miles/sec

What is the awnser to this The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same numbe
Rudiy27

The two true statements are the second statement (both lines contain the point (0,0)) and the fourth statement (If the Wilson family buys 3 pizzas, they will get more slices than the Hernandez family).

<h3>Which is the correct statement?</h3>

First, we know that the Hernandez family orders 3 large pizzas, such that they cut each pizza in the same number of slices, getting a total of 24 slices.

Then the number of slices that they get for each pizza is:

24/3 = 8

So from each large pizza, they get 8 slices.

So the relation between the number of pizzas bought (x) and the number of slices (y) is:

y = 8*x

In the other hand for the Wilson family we have the relation:

y = 10*x

Where y and x are the same ones as the defined above.

Then the true statements are:

<em>"If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices."</em>

This is true because Wilson family cuts each pizza in 10 slices, while the Hernandez family cuts each pizza in 8 slices.

<em>"For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line."</em>

The point (0, 0) means that if they buy 0 pizzas, they get 0 slices, which is true, so both relations contain this point.
