Given:
In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.
To find:
The measure of ∠P to the nearest degree.
Solution:
According to the law of cosine:
Using law of cosine in triangle NOP, we get
Putting the given values, we get
Taking cos inverse on both sides, we get
Therefore, the measure of ∠P is 33°.
Answer:
Step-by-step explanation:
we know that
The formula of an arithmetic sequence is
where
is the first term
is the nth term
n is the number of terms
d is the common difference
we have
substitute the given values
Answer:
-9, -8
Step-by-step explanation:
x+(x+1)=7+3(x+1)
x+x+1=7+3(x+1)
2x+1=7+3(x+1)
2x+1=7+3x+3
2x+1=3x+10
2x+1-1=3x+10-1
2x-3x=3x-3x+9
-1x/-1=9/-1
x=-9/-8
Answer: The answer for this question would be answer choice B "(0, 10) and (1, 15)". (0, 10) represents her starting amount and week saved, and (1, 15) would represent her saving for one week and having $15 total.
Hope this helps!
