Answer:

The scale factor for dilation can be worked out from the ratio of sides.

Here, for i.e, I'H'/IH = (8 + 4)/(4 + 2) = 12/6 = 2

Hope this helps!

:)

The scale factor for this dilation is 2

The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger. The initial figure is referred to as the pre-image, and the new figure that results from dilatation is known as the image.

As per the given data:

We are given a diagram having 2 triangles, we need to find the scale factor for this dilation.

For finding the scale factor, we can find the ratio of the corresponding sides of the two triangles.

Scale factor for ΔG'H'I' and ΔGHI :

= [tex]\frac{H'I'}{HI}[/tex]

From the given graph, we can clearly observe that

H'I' = 8 + 4 = 12

HI = 4 + 2 = 6

[tex]\frac{H'I'}{HI}[/tex] =  [tex]\frac{12}{6}[/tex] = 2

Hence, The scale factor for this dilation is 2.

Answer:

Naomi used 15 red tiles in her design.

Step-by-step explanation:

We need to add the total number of tiles that we know to find out the unknown value of red tiles. The blue tiles make up 1/2 of the design, or 50 tiles. Next we will add the green tiles, which Naomi used  15 of, as stated.

So far, we have figured out how many blue and green tiles we have. (50 blue, and 15 green, which is a total of 65).

Now we need to calculate the number of yellow tiles, which equal 1/5 of the design. 1/5 of 100 is 20.

Now we add all of our tiles that we already know. We have 50 red + 15 green + 20 yellow which = 85.

Now to find the unknown value of red tiles, we subtract our 85 other tiles from the 100 total tiles, and the ends us up with 15 red tiles.

the answer is v=113040

Step-by-step explanation:

Answer:

v=113040

Step-by-step explanation:

The value 1500 in the expression represents option A. The original number of grams of the radioactive isotope present.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given an exponential expression,

The number of grams of a radioactive isotope present after t years is 1,500(1/2)^t.

Here t is the number of years.

1/2 is the rate of decay of the isotope.

1500 is the initial amount.

We can say that the expression equals 1500 when t = 0.

But it is given that t > 0.

That is, 1500 is the amount which is equal to the original number of  grams of isotope.

Hence the number 1500 represents the original number of grams of the radioactive isotope present.

where s is the edge length of the cube-shaped box

Step-by-step explanation:

Let the edge length of the cube-shaped box=s

The edge length of a cube-shaped crate is the square of the edge length of a cube-shaped box.

To determine the number of boxes that can fit in the crate, we first find the volume of the crate and the box.

Therefore, the number of boxes that can fit in the crate

=Volume of Crate divided by Volume of Box

[tex]=\frac{s^6}{s^3}\\=s^{6-3}\\=s^3$ boxes[/tex]

Therefore, an expression for the number of boxes that can fit in the crate is [tex]s^3[/tex].

Answer:

212.5 cm² and 120 in²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

(4)

Here b = 25 and h = 17, thus

A = 0.5 × 25 × 17 = 212.5 cm²

(5)

Here b = 12 and h = 20, thus

A = 0.5 × 12 × 20 = 6 × 20 = 120 in²

Answer:

G) 60 m2

Step-by-step explanation:

1) Cut off the triangles and solve for the area of the rectangle.

    12 m x 4 m = 48m

2) Now that we have the big area of the rectangle, we just have to solve for the 2 triangles on the ends. Of the 18 m at the top, we uses 12 m to make the rectangle. That means there are 6 m that was not incorporated in the rectangle. Since there are 2 triangles, we can conclude that the base of each triangle is 3. Now we just have to use the equation for a triangle to find the area.

    4 m x 3 m x 1/2 = 6m (each triangle = 6m)

3) Add up all of the values to get the complete area

    48m + 6m + 6m = 60 m2

Answer:

A. y = 3sin(x-2) + 1

Step-by-step explanation:

The function whose graph is y= 3 sin (x-2)+1.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

As, From the graph that is provided to us we observe that,

when x=2 then f(x)=1.

1. y= 3 sin (x-2)+1

When x=2 gives y= 1

So, the equation satisfied.

2. y = 3 sin (x-2)+2

When x= 2 gives y= 2

So, the equation not satisfied.

3. y = 3 cos (x-2)+1

When x= 2 gives y > 1

So, the equation not satisfied.

Thus, the required function is y= 3 sin (x-2)+1.

Answer:

Let's denote:

x: number of bicycles

y: number of  skateboards

Then, we have:

x + y = 20

2x + 4y = 52

=> 2(20 - y) + 4y = 52

=> 2y = 12

=> y = 6 (number of skateboards)

=> x = 14(number of bicycles)
