Miguel Rodriguez borrowed $400 from his brother Julio to pay for books and tuition. He agreed to pay Julio in 6 months with simple annual interest at 6.4%.
a) How much will the interest amount to?
b) What amount must Miguel pay Julio at the end of 6 months?
A. The interest amount will be $12.8.
B. He must pay Annual amount of $412.8 at the end of 6 months.
What is interest?Interest is the idea that one party should be compensated for taking a risk and giving up the chance to use funds, while another party should be punished for using someone else's money.
The person who temporarily part with their money is entitled to compensation, and the person who temporarily uses those funds is frequently required to make this payment.
The simple interest is calculated as :
S.I = P×T×R
where,
S.I is the simple interest
P = Principal
T = Time period in years
R = Annual interest rate
The above problem,
Amount borrowed which would be the principal (P) = $400
Time period = 6 months = 1/2 year
Annual interest rate = 6.8% = 6.8/100 = 0.068
Substitute the details in formula
Simple Interest = 400×1/2×0.068
= 200 ×0.068
= 12.8
Amount to be paid = 400 + 12.8
= 412.8
Thus, the interest will be $12.8 and he must pay $412.8 at the end of 6 months.

To pay for a home improvement project that totals $16,000, Genesis is choosing between taking out a simple interest bank loan at 8% for 3 years or paying with a credit card that compounds monthly at an annual rate of 15% for 7 years. Which plan would give Genesis the lowest monthly payment?
The monthly credit card payment would be $511.11, which is lower than the monthly payment on the bank loan.
The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment.
The monthly payment on a bank loan would be $551.11, which is lower than the monthly credit card payment.
The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.
The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.
What is simple interest?
Simple interest is based on the principal amount of a loan or the first deposit in a savings account. Simple interest doesn't compound, which means a creditor will only pay interest on the principal amount and a borrower would never have to pay more interest on the previously accumulated interest.
The simple interest earned can be calculated by using this formula
A = P(1 + rt)
Where,
A is the future value.
P is the principal value.
r is the interest rate.
t is the time.
Now Substituting the values into the formula, we have,
A = 16,000[1 + (0.08 × 3)]
A = 16,000[1 + 0.24]
A = 16,000× 1.24
Future value, A = $19,840.
Following that, we will compute the monthly payment over a 36-month period as follows:
Monthly payment = Future value/Time
Monthly payment = 19,840/36
Monthly payment = $551.11
Similarly, we will compute the credit card's compound interest:
A = 16000[1 + (0.15/12)]⁽¹² ˣ ⁷⁾
A = 16000[1 + 0.025]⁸⁴
A = 16000× 1.025⁸⁴
A = 9000 × 3.49258954
Future value, A = $45425.80
Following that, we will compute the monthly payment over an 84-month period as follows;
Monthly payment = Future value/Time
Monthly payment = 45425.80/84
Monthly payment = $540.78.
Hence, the monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.

3. An arch in the shape of the upper half of an ellipse is used to support a bridge that is to span a river 20 meters wide. The center of the arch is 6 meters above the center of the river. Write an equation for the ellipse if the x-axis coincides with the water level and the y-axis passes through the center of the arch.
Answer:
the equation for the ellipse that describes the arch is:
(x^2/20^2) + (y^2/6^2) = 1
Step-by-step explanation:
An ellipse can be represented by the equation (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axes of the ellipse, respectively. In this case, the x-axis coincides with the water level and the y-axis passes through the center of the arch, so the center of the ellipse is at the point (0, 6).
For the arch in question, the semi-major axis is 20 meters (since the arch spans a river 20 meters wide) and the semi-minor axis is 6 meters (since the center of the arch is 6 meters above the center of the river).
So the equation for the ellipse that describes the arch is:
(x^2/20^2) + (y^2/6^2) = 1

Volume = 2094.40 ft³ (2 d.p.)

Given:
r = 10h = 20Substitute the given values of r and h into the formula for the volume of a cone and solve for V:
[tex]\implies V=\dfrac{1}{3} \pi \cdot 10^2 \cdot 20[/tex]
[tex]\implies V=\dfrac{1}{3} \pi \cdot 100 \cdot 20[/tex]
[tex]\implies V=\dfrac{1}{3} \pi \cdot 2000[/tex]

What is speed?Speed is the rate of change of position. It is the physical quantity that measures how quickly an object moves from one place to another. It is measured in units such as meters per second, kilometers per hour, or miles per hour. Speed is related to velocity, which is the measurement of how quickly an object moves in a specific direction. Speed is an important concept in physics and is necessary for understanding how the universe works.
Michelle makes a quarter turn to her right and Rebecca makes a three eight turn to her left. By making these turns, they will both end up facing north. A quarter turn to the right is the same as a three eight turn to the left. This is because a full turn is 360 degrees, so a quarter turn is 90 degrees and a three eight turn is also 90 degrees.

Solve the following equation for x 5x+3y=15
Answer:
x=3-3/5y
Step-by-step explanation:
5x+3y=15
5x=15-3y
x=(15-3y)/5
x=3-3/5y
Answer:
x= 3 y=5
Step-by-step explanation:
solving for x
5x + 3y = 15 Zero out the substitute
5x +( 3y * 0) = 15
5x + 0 = 15 Adding by zero can be ommited
5x = 15 Divide both side by 5
x = 3
if solving for y
5x + 3y = 15
(5x*0) + 3y = 15 zero out the substitute
0 + 3y = 15
3y = 15 devide by the number in front of x
y= 5
Brooklyn is trying to pick out an outfit for the first day of school. She can
choose from 6 pairs of pants, 8 t-shirts, 3 sweaters or hoodies, and 5 pairs of
shoes. How many different outfits does Brooklyn have to choose from?
Therefore , the solution to the given problem of combination comes out to be thus, we might deduce that Brooklyn has 720 options from which to choose.
What is the Combination?Combinations are mathematical procedures that count the number of possible configurations from a set of things, where the ordering of the selection of the elements is not important. You can select any set of items in any arrangement. Combinations and permutations are frequently wrong.
Here,
For the predicament,
six pants pairs
8 t-shirts
5 pairs equal 1 pair.
hoodies= 3
The formula to determine how many ways there are in a combination is = C. (n,r)
The number of possible outfit combinations is equal to C(n,r)* C(n,r)* C(n,r)* C (n,r)
=> C(6,1)*C(8,1)* C(5,1)* C(3,1) (3,1)
=> 6*8*5*3
=> 720
Therefore , the solution to the given problem of combination comes out to be thus, we might deduce that Brooklyn has 720 options from which to choose.
