Answer:
Step-by-step explanation:
Law of Cosines
x = √(40²+12² - 2·40·12·cos(37°)) ≅ 31.3 units
Answer:
the single decimal multiplier is 1.0058
Step-by-step explanation:
Let us have 100
Decreasing by 6% will be
100 - 0.06(100)
= 94
Increasing by 7%
= 94 + 0.07(94)
= 100.58
So
to get the single decimal multiplier,
we have 100.58/100 = 1.0058
Answer: 90
Step-by-step explanation:
15% of 90 = 13.5
