Two complementary angles sum is 90 degrees.
Angle 1 = x
Angle 2 = 2x ( two times angle 1)
Equation: x + 2x = 90
Solve:
Combine like terms:
3x = 90
Divide both sides by 3:
X = 90/3
X = 30
Angle 1= 30
Angle 2 = 60

Answer:
297.01 In
Step-by-step explanation:
Answer: A (t) = 24500 (1+0.03)^t
Step-by-step explanation:
Hi, to answer this question we have to write a growth function:
A = P (1+r) ^t
Where:
A = amount after growth
P = initial amount
r = growth rate (in this case is yearly, since she gets a 3% raise each year)
t = years
Replacing with the values given:
The growth rate must be in decimal form (divided by 100)
A (t) = 24500 (1+3/100)^t
A (t) = 24500 (1+0.03)^t

.
The formula is length x width x height / 3 or V = lwh/3.
So for the first one: 13 * 14 * 6 = 1,092
1092 / 3 = 364 cm^3 (cubic centimeters). That formula works for all the examples on that page.
