a) Sammie earns
£320×4% = £12.80
each year.
Joel earns
£420×3% = £12.60
each year.
Sammie earns the most interest.
b) Joel's interest after 5 years is
£12.60×5 = £63
so the total amount of money Joel will have is
£420 +63 = £483
Answer: The slope is 80.75.
Step-by-step explanation: You just use the formula for rise over run.
Answer:
See below.
Step-by-step explanation:
Using the Rational Roots Theorem:
Factors of 3: 1, 3 ( = p).
Factors of 6: 1,2,3,6 ( = q).
Possible real roots are a 1 or 3 from p / q = +/- 1/1, +/- 3/1 , +/-1/2, +/- 1/3 , +/- 1/6, +/- 3/2.
To solve this find the common number that can be divided by both and use that number.
In this case, 4 is divisible by both 4 and 12, and thus the final expression would be
4(d + 3e).
Answer:
D
Step-by-step explanation:
It turns out from similar triangles, that 7/BD = BD / 18. Use triangles ABD and BDC to show this relationship. Solving this equation will give you BD
BD^2 = 7*18
BD^2 = 126 Just leave it in this form. Do your rounding at the end.
Because triangle BDC is a right angle triangle, use the Pythagorean Theorem to solve for m
m^2 = BD^2 + 7^2
m^2 = 126 + 49
m^2 = 175 Take the square root of both sides.
sqrt(m^2) = sqrt(175)
m = 13.22
so the answer is D
