Answer:
Multiply by 3 on both sides of the equation.
2.78 × 3 = 8.34, so t = 8.34.
Substitute 8.34 for t to check the solution.
Step-by-step explanation:
To solve the equation = 2.78
we will use the steps below to solve this equation;
First, multiply by 3 on both-side of the equation. That is;
× 3= 2.78 × 3
On the left hand side of the equation 3 will cancel-out 3, leaving us with just t while 3 will be multiply by 2.77 on the right-hand side of the equation to give 8.34
t = 8.34
we can further substitute 8.34 for t to check the correctness of the solution
that is;
= 2.78

Given that a unshaded rectangle is inscribed in a shaded circle, the area of the shaded region is 72.67m².
Given that a unshaded rectangle is inscribed in a shaded circle.
- Diameter of the circle d = 13m
- Radius r = d/2 = 13m/2 = 6.5m
- Dimension of length of the rectangle l = 12m
- Dimension of width of the rectangle w = 5m
- Area of the shaded region As = ?
First we calculate the area of the shaded circle.
A = πr² = π × ( 6.5m )²
A = 132.665m²
Area of the shaded circle is 132.665m².
Area of the unshaded rectangle will be;
A = l × w
A = 12m × 5m
A = 60m²
Area of the unshaded rectangle is 60m².
Now, area of the shaded region will be;
= Area of the shaded circle - Area of the unshaded rectangle
= 132.665m² - 60m²
= 132.665m² - 60m²
= 72.67m²
Given that a unshaded rectangle is inscribed in a shaded circle, the area of the shaded region is 72.67m².

He can drink 2/5 of the 8 3/4 sodas.
The answer is 7/2 or 3 1/2 sodas.
Of course, Fred would be better off is he drank water instead of soda. :-)
Answer:
25.85 years
Step-by-step explanation:
Use the formula for continuous compounding amount:
A = Pe^(r*t), where r is the interest rate as a decimal fraction, P is the initial amount, and t is the time in years.
Here we have:
A = $200e^(0.0425*t) = 3($200) (this is triple the original amount)
Solve this for t. Divide both sides by $200 and then use natural logs:
1e^(0.0425*t) = 3
Then 0.0425*t = ln 3 = 1.0986
Dividing both sides by 0.0425 will isolate t:
1.0986
t = --------------- = 25.85 years
0.0425
