Answer:
r = 0.05 or 5%
Step-by-step explanation:
3450 = 3000 + (3000 · r · 3)
450 = 9000 · r
450/9000 = r
r = 0.05 or 5%
Answer:
x is approximately 48.2.
Step-by-step explanation:
Use the trig function of cosine, or adjacent over hypotenuse.
cos theta = adjacent / hypotenuse
Substitute variables.
cos x = 10 / 15
Apply inverse cosine to both sides.
x = cos^-1(10/15)
Evaluate.
x ≈ 48.2
Answer:
16
Step-by-step explanation:
Since the ratio is constant, you can do divisions here.
4/3 = 4/3
6/8 = 4/3
Etc.
From here, you take 12, and multiple it by 4/3, and get 16.
