For #13
2squared+6squared=x
4+36=40
The square root of 40 is 6.32 so 6.3 is the length of the missing side :)
Investment at 2% is 22,000
Investment at 3% is 13,000
Two angles are supplementary when they <span>add up to 180 degrees.
x = </span><span>smaller angle
</span>2x+3 =<span> larger angle
x + 2x + 3 = 180
3x = 180 - 3
3x = 177
x = 177/3
x = 59</span>° ← smaller angle
2x + 3 = 2*59 + 3 = 121° ← larger angle
Answer:
$13.5
Step-by-step explanation:
Given data
We are given that the tax per CD is $1.30
Hence for the 3 CDs the total tax = 3*1.3= $3.9
Also, the cost of the three CDs before tax = 44.4-3.9
=$40.5
Hence the cost of each CD before tax is
=40.5/3
=$13.5
