13.5/3 = 4.5
He hiked for 4.5 hours.
Angle 3 is 78 degrees. same as angle 5.
Answer:
Step-by-step explanation:
BD=BL(given)
so ∠BLD=∠BDL=3x
90+∠GBD+30=180
∠GBD=180-120=60°
Also ∠GBD=∠BLD (given)
so ∠BDL=60°
3x=60
x=20°
After 1 year, the initial investment increases by 7%, i.e. multiplied by 1.07. So after 1 year the investment has a value of $800 × 1.07 = $856.
After another year, that amount increases again by 7% to $856 × 1.07 = $915.92.
And so on. After t years, the investment would have a value of 
.
We want the find the number of years n such that
Solve for n :
The amount invested in the first account is $9,300 while the amount invested in the second account is $8,800.
<h3>
How do we calculate the amount invested?</h3>
Let x represents the amount invested in the first account.
Therefore, we have:
Amount invested in the second account = x - 500
Interest income from first account = 3% * x = 0.03x
Interest income from second account = 5% * (x - 500) = 0.05x - 25
Total interest income = 0.03x + 0.05x - 25 = 719
Solving for x, we have:
0.08x = 719 + 25
x = 744 / 0.08
x = $9,300
Substituting for x, we have:
Amount invested in the second account = $9,300 - $500 = $8,800
