How much time will it take to earn $760.00 in interest if you deposit $3,200.00 into a simple interest account earning 4.5% annum Simple interest
Using the formula of simple interest, the time it will take to accumulate to $3200 at a rate of 4.5% is 71.35 years
What is Simple InterestSimple interest is a method of calculating the interest charge on a loan or deposit. It is based on the principle of earning interest only on the initial amount (principal) that was borrowed or deposited.
The formula for simple interest is:
I = P * r * t
where:
I is the interest amount
P is the principal amount
r is the interest rate (expressed as a decimal)
t is the time period (in years)
Substituting the values into the formula;
A = P(1 + rt)
3200 = 760(1 + 0.045(t))
3200 = 760 + 34.2t
34.2t = 3200 - 760
34.2t = 2440
t = 2440 / 34.2

Answer:
Step-by-step explanation:
Here's a step by step explanation of how to calculate the number of cakes baked if the bakery baked 96 loaves of bread:
First, determine the number of sets of 12 loaves of bread that were baked:
96 loaves of bread ÷ 12 loaves per set = 8 sets of 12 loaves
Next, determine the number of cakes baked for each set of 12 loaves of bread:
For every set of 12 loaves, 5 cakes are baked.
Finally, multiply the number of sets by the number of cakes baked per set to find the total number of cakes baked:

1. An arithmetic sequence is given using the recursive definition: b₁ = 8 and b₁ =b₁-₁-3. Which of the
n-1
following is the value of b,? Show the work that leads to your answer.
(1) 14
(2) 2
(3) 6
(4) 4
Answer:
To find the value of b_n in an arithmetic sequence given by the recursive definition b_1 = 8 and b_n = b_{n-1} - 3, we can use the formula for the nth term in an arithmetic sequence:
b_n = b_1 + (n-1)d
where d is the common difference. In this case, d = -3.
So, we can plug in the values for b_1 and d to find b_n:
b_n = 8 + (n-1)(-3)
b_n = 8 - 3(n-1)
Now, to find the value of b_n for a specific n, we just need to substitute the value of n into the equation for b_n. For example, if we want to find b_14, we would substitute n = 14:
b_14 = 8 - 3(14-1)
b_14 = 8 - 3(13)
b_14 = 8 - 39
b_14 = -31
So, the value of b_14 is -31, and the answer is (1) 14.
B) The area of a triangle = ½ the base the

What is the area of an equilateral triangle where
every side measures 10 cm?
The area of the equilateral triangle with side length 10 cm is 25 cm².
What is triangle ?
Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.
To find the area of an equilateral triangle, we need to find the height first. The height of an equilateral triangle is equal to the length of the perpendicular line from the center of the triangle to one of its sides.
To find the height, we can divide the equilateral triangle into two 30-60-90 triangles. The height is equal to half of the hypotenuse of one of these triangles, which can be calculated as:
10 cm / 2 = 5 cm
Now that we have the height, we can find the area of the equilateral triangle as follows:
Area = ½ * base * height
Area = ½ * 10 cm * 5 cm
Area = 25 cm²
Hence, The area of the equilateral triangle with side length 10 cm is 25 cm².

Find the present value of an annuity due with a monthly payment of $300 at 6% interest compounded monthly for 10 years.
Answer: The present value of an annuity due with a monthly payment of $300 at 6% interest compounded monthly for 10 years can be calculated using the formula:
PV = PMT * [ (1 - (1 + r)^-n) / r ] * (1 + r)
where:
PMT = $300 (the monthly payment)
r = 0.06/12 (the monthly interest rate)
n = 10*12 (the number of periods over 10 years, with 12 months in a year)
Plugging in the values into the formula, we get:
PV = $300 * [ (1 - (1 + 0.06/12)^-n) / (0.06/12) ] * (1 + 0.06/12)
PV = $300 * [ (1 - (1 + 0.06/12)^-(10*12)) / (0.06/12) ] * (1 + 0.06/12)
PV = $300 * [ (1 - 1.06^-120) / (0.06/12) ] * (1 + 0.06/12)
PV = $300 * [ (1 - 0.379362539) / (0.06/12) ] * (1 + 0.06/12)
PV = $300 * [ (0.620637561) / (0.06/12) ] * (1 + 0.06/12)
PV = $300 * 10.34300138
PV = $31,029.
So the present value of the annuity due is $31,029. This means that if you were to invest $31,029 today, you would receive a monthly payment of $300 for 10 years at 6% interest compounded monthly.

An angle measures 64.2° more than the measure of its complementary angle. What is the measure of each angle?
On solving the provided question, we can say that first angle is 37.9° . second angle will be 52.1°.
What are angles?An angle is a fοrm in Euclidean geometry made composed of two rays, called the angle's sides, that meet at a pοint in the middle known as the angle's vertex. In the plane where the rays are placed, twο rays can produce an angle.
An angle is alsο produced when two planes intersect. They're knοwn as dihedral angles. In plane geοmetry, an angle is the form that two rays or lines with a commοn termination might take. The Latin word "angulus," which means "hοrn," is where the English word "angle" comes from. The two rays, also knοwn as the sides of the angle, have a common termination knοwn as the vertex.
x = first angle
Complementary angle is 14.2 degrees more than the cοmplementary angle.
First angle = x
Second angle = x + 14.2°
Complementary angle
x+x+14.2=90
2x+14.290
2x 90 14.2
2x = 75.8 x = 37.9
First angle is 37.9°.
Second angle will be:

The exact perimeter of the segment is 54.13 inches, and the exact area of the segment is 301.44 square inches.
What is perimeter and area enclosed in circle?
A circle is also defined by two properties: area and perimeter. The formulas for both the measures of the circle are given by; Area of a circle = πr². The perimeter of a circle = 2πr.
Let's call the center of the circle O and the endpoint of the arc A. Let's also call the endpoint of the chord that defines the segment B. Then we have an isosceles triangle OAB, where OA = OB = 24 inches.
1) The perimeter of the segment is equal to the length of the arc plus the length of the chord. To find the length of the arc, we can use the formula:
Arc length = (Ф / 360) * 2πr,
where Ф is the measure of the angle in degrees, r is the radius (which is 24 inches in this case), and π is pi.
In this case, the measure of the angle is 60°, so the length of the arc is:
Arc length = (60 / 360) * 2π * 24 inches
Arc length = (1/6) * 2π * 24 inches
Arc length = 4π inches
To find the length of the chord, we can use the formula:
Chord length = 2r * sin(Ф/2), where r is the radius and Ф is the measure of the angle in radians.
First, we need to convert the angle measure from degrees to radians:
60° = 60 * (π / 180) radians = π / 3 radians
Now, we can find the length of the chord:
Chord length = 2 * 24 * sin(π / 6)
Chord length = 24 * 2 * sin(π / 6)
Chord length = 24 * √3 inches
Finally, we can add the length of the arc and the chord to find the perimeter:
Perimeter = 4π + 24 * √3
Perimeter = 4π+41.57
Perimeter = 54.13 inches
2) To find the area of the segment, we can use the formula:
Area = (Ф/ 360) * πr², where Ф is the measure of the angle in degrees and r is the radius.
In this case, the measure of the angle is 60°, so the area of the segment is:
Area = (60 / 360) * π * 24² square inches
Area = (1/6) * π * 576 square inches
Area = 96π square inches
Area = 301.44 square inches
So, The exact perimeter of the segment is 54.13 inches, and the exact area of the segment is301.44 square inches.

16% of the cows have already had calves. 32 have not had calves yet. How many are in the herd?
Answer:
There are approximately 38 cows in the herd.
Step-by-step explanation:
In this problem, we are asked to find the number of cows in a herd, given that 16% of the cows have already given birth to calves and 32 have not yet done so.
Assuming there are no other types of cows in the herd, we can determine that the 32 cows that have not had calves make up 84% of the herd, since they are what is left over when 16% is subtracted from 100% (the whole herd).
[tex]100\%-16\% = 84\%[/tex]
We can now create a equation that shows that 84% of the herd is 32 cows, representing the total number of cows in the herd as x.
[tex]32 \text{ cows} = 84\% \cdot x[/tex]
Finally, to solve for the number of cows in the herd, we can multiply both sides by 100/84.
[tex]\dfrac{100}{84}(32 \text{ cows}) = (84\% \cdot x)\dfrac{100}{84}[/tex]
[tex]x \approx 38 \text{ cows}[/tex]
So, there are approximately 38 cows in the herd.
