Answer:
x ≈ 6.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
( multiply both sides by 10 )
10 × sin40° = x , thus
x ≈ 6.4 ( to the nearest tenth )
2x ! the number would be x and 2x is 2 times x!
The balance in the account after 13 years is $8233.79.
<h3>Compound interest: Calculating balance in an account</h3>
From the question, we are to use the compound interest formula to compute the balance in the account
From the compound interest formula, we have that
A = P(1 + r/n)^nt
Where A is the amount
P is the principal
r is the interest rate
n is the number of times compounded per year
and t is the time.
From the given information,
P = $7000
r = 3.3%= 0.033
n = 1
t = 13
Putting the parameters into the formula
A = P(1 + r/n)^nt
A = 7000(1 + 0.033/1)^(1×5)
A = 7000(1 + 0.033)^5
A = $8233.79
Hence, the balance is $8233.79

Answer:
Answer: C
Step-by-step explanation:
Start with 20.50 then subtract 4.00. then, keep subtracting 2.75
Answer:
C - 7315
Step-by-step explanation:
Using the combination formula.
22! / (4!(22-4)!) = 7315
Combination is like saying I want meat-cheese-lettuce-tomato and this is the same as cheese-meat-tomato-lettuce. (same toppings, different order)
