Answer:

100°

Step-by-step explanation:

if the entire angle ABC is 130° and angle DBC is 30° (which is part of angle ABC) you subtract the 30° from the entire angle ABC (130°) to get 100° for angle ABD

Answer:

100

Step-by-step explanation:

/_ ABC = /_ ABD + /_ DBC

Given: /_ABC = 130 and /_DBC = 30

* plug in known values *

130 = /_ ABD + 30

Subtract both sides by 30

130 - 30 = 100

30 - 30 cancels out

We're left with /_ABD = 100

Julien's parents want $64,000 at the end of 3 years. They put their money in an account that yields 10% per year compounded mont
Leto [7]

Answer: \$47,471

Step-by-step explanation:

Given

Julien's parents want $64,000 at the end of 3 years

The rate of interest is 10% annually

Suppose they invested P amount initially

So, compound interest, compounded monthly is

\Rightarrow A=P\left( 1+\frac{r}{n}\right)^{nt}\quad [\text{n=Numner of compounding periods}]\\\\\text{Insert the values}\\\Rightarrow 64,000=P\left( 1+\frac{0.10}{12}\right)^{12\times 3}\\\\\Rightarrow 64,000=P\left( 1+\frac{10}{12}\right)^{36}\\\\\Rightarrow P=\dfrac{64000}{1.3481}\\\\\Rightarrow P=\$\ 47,471.37\approx \$ 47,471
