Answer:
7 years
Step-by-step explanation:
Simple interest is given by
I = PRT where I is the interest, P is the principle r is the rate and t is time
If we have 249 in the account and started with 200,
the interest is 249-200 = 49
The principle is 200 and the rate is 3.5% or in decimal form .035
Putting into the equation
49 = 200 (.035) t
49 =7t
Divide each side by 7
49/7 = 7t/7
7 =t
It will take 7 years
Answer:
Length of the garden = 69.28 meters.
Step-by-step explanation:
See the attached diagram.
Let CD is the pole with a height of 30 m and the elevation of the top of the pole from the endpoints of the length A and B are 60° and 30° respectively.
So, ∠ DAC = 60° and ∠ DBC = 30°
Now, Δ ACD is a right triangle and
⇒
meters.
Now, from Δ BCD which is a right triangle,
⇒
meters.
Hence, AB = AC + CB = 17.32 + 51.96 = 69.28 meters. (Answer)
Answer:
The number is 4.
Step-by-step explanation:
The difference of twice a number and 12 is 2x - 12.
Multiplying by 5 gives 5(2x - 12)
So 5(2x - 12) = -20
Solving for x
10x - 60 = -20
10x = -20 + 60 = 40
x = 40/10
x = 4.
