Answer:
10.5
Step-by-step explanation:
1/2 as a decimal is 0.5
so 10 is a whole number so i dont have to change it.
then answer is 10.5
Answer: m ⇒ e ∨ p
Step-by-step explanation:
First look at the statement and locate the connectives ( these are words which connect sentences such as: and, or, implies, is equivalent and not.) Each of these connectives have a symbol/ variable.
- In this case the connectives are "only if" and "or" these are important because we will not attach propositional variables to them, where:
⇒ = " only if"
∨ = "or"
- Convert the phrases into variables where:
m = " You can see the movie"
e = "You are over 18 years old"
p = " you have the permission of a parent"
- Construct the statement sequentially.
You can see the movie (m) only if (⇒) you are over 18 years old (e) or (∨) you have the permission of a parent (p)
- Remove the phrases and you'll have your answer:
m ⇒ e ∨ p
3x-7=-2-6
3x=-2-6+7
3x=-1
X=-3
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for B
B = 180° - (90 + 47)° = 180° - 137° = 43°
-------------------------------------------------------------
tan47° = 
= 
Multiply both sides by 14
14 × tan47° = a, thus
a ≈ 15.0 (to the nearest tenth )
---------------------------------------------------------------
cos47° = 
= 
Multiply both sides by c
c × cos47° = 14 ( divide both sides by cos47° )
c = 
≈ 20.5 ( to the nearest tenth )
Solve the exponents first:
Add the results together:
The answer is
35.
