Reflectional symmetry<span> exists when the figure can be folded over onto itself along a line. This line is called the "line of symmetry". The correct answers for this would be.
</span>-A line of symmetry will connect a vertex and a midpoint of an opposite side
-it has 7-fold symmetry.
Given:
Latasha spends $3.35
Helen spends 4 times as much as Latasha.
Dee spends $7.50 more then Helen.
To find:
The amount Dee spends.
Solution:
It is given that, Latasha spends $3.35.
Helen spends 4 times as much as Latasha.
So, Helen spends = 4 × $3.35
= $13.40
Dee spends $7.50 more then Helen.
Dee spends = $13.40+$7.50
= $20.90
Therefore, dee spends $20.90.
D. P(A x B)
To work out the success of both events you have to multiply them together. I'd seriously reccomend learning this rule as it's very important later on in mathematics as it's basically the foundation of all probability statistics.
Use the substitution method
(9,90) y= 10x
90= 10(9)
90= 90
Answer is yes
