N + (n+1) + (n+2) + (n+3) = 90
if n is the first number, then the next number is 1 more than n, the next number is 2 more than n, etc.
Simplify the above expression:
4n + 6 = 90
4n = 84
n = 21
n+1= 22
n+2 = 23
n+3 = 24
Answer:
Step-by-step explanation:
A = P[1 + (r/n)]^(nt)
Look the formula up online to find out what each variable represents if needed.
We are solving for P, which is the principal amount 5 years back.
Substitute 11,000 for A (total amount), 4.5% for r(rate), 2 for n(number of times -- in this case, semiannually), and 5 for t(time -- 5 years).
11000 = P[1+(0.045/2)]^(2x5)
11000 = P (1.0225)^10
11000 = P (1.2492) approx.
Divide both sides by 1.2492 to find P.
P = $8805.64 (approx)

Answer:
25% or 1:4
Step-by-step explanation:
When it says 1 in 4, that can be expressed as a 25% chance or as a ratio of 1:4. Since you are taking 4 people at random, and the chance is one in four, you have a 1/4th chance, therefore a 25% chance or a 1:4.
Answer:
The hypotenuse is 25 inches.
Step-by-step explanation:
This is a right triangle, so the Pythagorean Theorem applies.
I will assume you know about the Pythagorean Theorem, therefore I will not define it.
Here, I am solving for the hypotenuse.
