A farmer created a crop circle that is a square inside a circle. The square contains the crop of wheat, and the part outside the square is flat. The circle has a radius of 25meters, and the square has a side length of 35 meters. What is the area of the flat region within this crop circle? Use 3.14.
Answer:
738.75m^2Step-by-step explanation:
this problem is on the mensuration of flat shapes.
first, we need to solve for the area of the circle
area of circle= πr^2
area of circle= 3.142*25^2
area of circle= 3.142*625
area of circle= 1963.75m^2
the area of the square
area of square= l^2
area of square= 35^2
area of square= 1225m^2
the area of the flat region within this crop circle is
area of circle-area of square
= 1963.75-1225
=738.75m^2
Account A and Account B both have a principal of $2,000 and an annual interest rate of 2%. No additional deposits or withdrawals are made. Account A earns simple interest. Account B earns interest compounded annually. Compare the amounts in the two accounts after 20 years. Which earns more interest? How much more?
After 20 years, account (A or B) will have earned $____ more.
Answer:
Account B earns more interest.
After 20 years, account B will have earned $171.89 more.
Step-by-step explanation:
Let's calculate the total for each account.
Account A:
Account A earns simple interest. We know that the principal value is $2000 and the interest rate is 2% or 0.02. We can use the simple interest formula:
[tex]A=P(1+rt)[/tex]
Where A is the future value, P is the principal, r is the rate, and t is the time in years.
So, let's substitute 2000 for P, 0.02 for r, and 20 for t. This yields:
[tex]A=2000(1+0.02(20))[/tex]
Multiply and add:
[tex]A=2000(1+0.4)=2000(1.4)[/tex]
Multiply. So, the total amount of money in Account A after 20 years is:
[tex]A=\$2800[/tex]
Since we initially deposited $2000 and our total is now $2800, this means that we earned an interest of [tex]2800-2000=\$ 800[/tex]
Account B:
Account B earns compound interest. Like Account A, Account B has a principal value of $2000 and the interest rate is 2% or 0.02. We also know that it's compounded annually, so once per year. We can use the compound interest formula:
[tex]B=P(1+\frac{r}{n}})^{nt}[/tex]
Where B is the future value, P is the principal, r is the rate, n is the times compounded per year, and t is the time in years.
So, let's substitute 2000 for P, 0.02 for r, n for 1 (since it's compounded annually), and t for 20. This yields:
[tex]B=2000(1+\frac{0.02}{1})^{(1)(20)}[/tex]
Simplify this to acquire:
[tex]B=2000(1.02)^{20}[/tex]
Evaluate. Use a calculator. So, after 20 years, the amount of money in Account B is:
[tex]B\approx\$2971.89[/tex]
Since our principal was $2000, this means that we earned an interest of approximately [tex]2971.89-2000=\$ 971.89[/tex].
So, Account A earned an interest of $800 and Account B earned an approximate interest of $971.89.
So, Account B earned more interest.
And it earned [tex]971.89-800=\$ 171.89[/tex] more than Account A.
And we're done!

The explicit rule for a sequence and one of the specific terms is given. Find the position of the given
term.
f(n) = 1.25n+ 12.5; 25
25 is the BLANK th term
Answer:
10.2
Step-by-step explanation:
F(n) is basically a fancy substitute for y
25= 1.25n + 12.25
subtract 12.25 from both sides
12.75=1.25n
n=10.2
plug back in to double check
1.25(10.2) + 12.25
it equals 25, therefore the answer is
10.2

Answer:
x = 6 , − 6
Step-by-step explanation:
Answer:
x = 4x = -2Step-by-step explanation:
Solving for x
|2x-2|=61. 2x - 2 ≥ 0 ⇒ 2x ≥ 2 ⇒ x ≥ 1
2x - 2 = 62x = 8x = 42. 2x - 2 < 0 ⇒ 2x < 2 ⇒ x < 1
2x - 2 = -62x = -4x = -2Alicia watched a drone take off from a bridge. The height of the drone (in meters above the ground) t minutes
after takeoff is modeled by
h(t) = -3t2 + 12t +96
Alicia wants to know when the drone will land on the ground.
1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the
equation
h(t) =
2) How many minutes after takeoff does the drone land on the ground?
minutes
Answer:
h(t) = -3(t-8)(t+4). and 8 minutes
Step-by-step explanation:
The function can be written as: h(t) = - 3(t² - 4t - 32). As per quadratic equation, after take off, the drone will land on the ground after 8 minutes.
What is a quadratic equation?A quadratic equation is an equation that contains a variable with highest degree of 2.
Given, the height of the drone t minutes after take off is modeled by
h(t) = - 3t² + 12t + 96 = - 3(t² - 4t - 32)
Therefore, the function can be written as: h(t) = - 3(t² - 4t - 32)
Therefore, we can write the equation as:
t² - 4t - 32 = 0
⇒ t²- 8t + 4t - 32 = 0
⇒ t(t - 8) + 4(t - 8) = 0
⇒ (t + 4)(t - 8) = 0
Hence, (t + 4) = 0 and (t - 8) = 0
Therefore, t = -4, 8.
As 't' can't be negative, therefore, t = 8.
Therefore, after take off, the drone will land on the ground after 8 minutes.

Three quarts of a latex enamel paint will cover about 120 square feet of wall surface. How many quarts are needed to cover 161 square feet of kitchen wall and 119 square feet of bathroom wall? Nothing quarts of a latex enamel paint are required
Answer:
7 quarts
Step-by-step explanation:
We can solve this problem by using the rule of three. As seen in the picture below we need to find the X. We do this by multiplying 161 sq. ft. diagonally by 3 quarts and then dividing by 120 sq. ft. This will give us the number of quarts needed for the kitchen wall. Then we simply repeat the process for the bathroom wall and we are done. Like so ...
[tex]\frac{161 sq. ft. * 3 quarts}{120 sq. ft.} = x[/tex]
[tex]4.025 quarts = x[/tex]
[tex]\frac{119sq. ft. * 3 quarts}{120 sq. ft} = x[/tex]
[tex]2.975 quarts = x[/tex]
Therefore we need 4.025 quarts for the kitchen wall and 2.975 quarts for the bathroom wall ... making that a total of 7 quarts.
