To solve this exercise you must follow the proccedure shown below:
1. You have the the lengths of the sides of equilateral triangle which is inscribed inside a similar triangle are 10 cm. Therefore, the area is:
A1=bxh/2
A1=10 cmx10 cm/2
A1=50 cm²
2. <span>The larger triangle is dilated with a scale factor of 3 from the smaller triangle. Using the ratio of the area:
(1/3)</span>²<span>=50/A2
1/9=50/A2
A2=450 cm</span>²
<span>
3. The area of the shaded region is:
At=A2-A1
At=400 cm</span>²
Answer:
A. -6.5
B. 31
C.-25
Step-by-step explanation:
A. -78/12 = -6.5 ( A negative number divided by a positive number should result as a negative)
B. 31 (A negative divided by a positive should result as a positive)
C. -25 ( A positive divided by a negative should result as a negative)
A very helpful way to divided numbers is to first ignore the negative signs and do the division first. Then you should add the negative or positive sign in the end.
Answer:
What's the question?
Step-by-step explanation:
I hope you have a good night btw!!!
3/4 + 4 1/2 = 5 1/4
If you mean that the dictionary is 41/2 then the answer = 3/4 + 20 1/2 = 21 1/4. That's a big diction though and not likely measured correctly.
Given:
The table of values is
x y
-4 2
-3 5
-2 8
-1 11
To find:
The slope of the line that contains these points.
Solution:
From the given table consider any two point.
Let the line passes through the points (-4,2) and (-3,5). So, the equation of the line is
Using distributive property, we get
Therefore, the required equation of line is .
