answer:
22 weeks
step-by-step explanation:
- set up a proportion
- use x for how long it would take her
- cross multiply to solve
39 / 2 = 429 / x
429 (2) = 39x
858 = 39x
x = 22
- it would take her 22 weeks
- you can change the units by conversion based on what is asked
This is the concept of scale factors; The length of the larger figure will be calculated as follows;
linear scale factor=[length of larger figure]/[length of smaller figure]
plugging the values in the above formula we get:
let the length of the larger figure be x;
thus;
x/12=4/3
multiplying both sides by 12 to solve for x we get:
12*x/12=4/3x12
x=16
thus the length of the larger figure is x=16
I think its 40ft i hope it helps
Answer:
- 39
Step-by-step explanation:
x³ - 3y
Put x as -3 and y as 4.
-3³ - 3(4)
Solve for power and multiply.
-27 + - 12
Add the terms.
- 39
Answer: 3. Point F.
Step-by-step explanation:
The missing statement is: Point F' corresponds to______
- Point D.
- Point E'.
- Point F.
- Point E.
The missing picture is attached.
By definition, the original figure (The figure before the transformation) is called "Pre-image" and the figure obtained after the transformation is called "Image".
You know that the triangle is obtained by transforming the triangle ; therefore, the triangle is the Pre-Image and the triangle is the Image.
Therefore, given the point (which is a vertex on the triangle ) you can identify that its image is (which is the corresponding vertex on the triangle ).
You can also verify it by seeing the angle and the angle . Notice tthat:
Therefore, based on the explained before, you can conclude that the point corresponds to the point .
