Answer:
75
Step-by-step explanation:
By "composite" we mean "numbers that can be factored further."
The numbers between 10 and 20 but not including 10 or 20 are:
12, 14, 15, 16, 18
12, 14, 15, 16 and 18 are all composite numbers (all can be factored).
Their sum is 75.
Answer:
65°
Step-by-step explanation:
Sum of interior angles of a triangle = 180°
⇒ m∠EAB = 180 - 90 - 70 = 20°
⇒ m∠DAG = 90 - 45 - 20 = 25°
⇒ m∠AGD = 180 - 90 - 25 = 65°
ΔADG ≅ ΔAFG
⇒ m∠AGD = m∠AGF = 65°
ΔABE ≅ ΔAFE
⇒ m∠AEB = m∠AEF = 70°
Answer:
x = 12.1
Step-by-step explanation:
20 − (z + 7) = 0.9
Distribute the minus sign
20 -x -7 = .9
Combine like terms
13 -x = .9
Subtract 13 from each side
-x = -12.1
x = 12.1
Answer:
20 years
Step-by-step explanation:
<u>Continuous Compounding Formula</u>

where:
- A = Final amount
- P = Principal amount
- e = Euler's number (constant)
- r = annual interest rate (in decimal form)
- t = time (in years)
Given:
- A = $10,000
- P = $5,000
- r = 3.5% = 0.035
Substitute the given values into the formula and solve for t:









Therefore, it will take 20 years (to the nearest year) for the initial investment to double.
