A first-time homebuyer is comparing mortgage rates.
Option A offers the homebuyer 5.25% annual simple interest.
Option B offers the homebuyer the same interest rate but compounded semiannually.
If the repayment period is the same length for both loans, which option will result in the least amount of interest added to the loan?
O Option A will have the least amount of interest because simple interest generates earnings from both principal and interest.
O Option A will have the least amount of interest because simple interest generates earnings from principal only.
O Option B will have the least amount of interest because compound interest generates earnings from principal only.
O Option B will have the least amount of interest because compound interest generates earnings from both principal and interest.
If the repayment period is the same length for both loans, the interest option that will result in the least amount of interest added to the loan is B. Option A will have the least amount of interest because simple interest generates earnings from principal only.
What is the simple interest?The simple interest is the interest system that does not compute interest on accumulated interest.
Unlike simple interest, compound interest charges interest on accumulated interest.
Thus, the simple interest system applies the interest rate on the principal only for each period to determine the amount of interest.

You have 10 gallons of lemonade to sell. (1 gal ≈

Number of packs of cups to be purchased = 5 packs and Number of cups remaining if 80% lemonade is sold = 85 cups.
What are the two equations for a cone's volume?The volume of cone is calculated using the formula (1/3)r2h, where "h" stands for the cone's height and "r" for the base radius. As a result, (1/3)r2 is the cone's volume in terms of the slant height "L." (L2 - r2).
Volume of a cone:Volume of a cone is given by the expression,
V = 1/3πr²h
Here,
r = radius of the cone
h = Height of the cone
Radius of the cone = = 4 cm
Height of the cone = 11 cm
Amount of lemonade = 10 gallons
Volume of one cone = 1/3π(4)²× 11
= 184.307 cm³
Covert the gallons into cubic cm,
∵ 1 gallon = 3785 cm³
∴ 10 gallons = 37850 cm³
∵1 cones are represented by a volume of 184.307 cm3.
∴ 1 cm³ will represent the volume = 1/184.307 cup
∴ 37850 cm³ will represent the volume = 37850/184.307 cups
= 205.36 cups
= 205 cups
Therefore, number of packs of cups to be bought = 205/50
= 5 packs
b). If 80% of the lemonade are sold, amount of lemonade sold = 10 × 80/100
= 8 gallons
Volume of 8 gallons lemonade in cm³ = 8 × 3785
= 30280 cm³
Therefore, number of cups to be used = 30280/184.307 cups
= 164.29 cups
≈ 164 cups
Number of cups purchased = 250
And there are 250 cups left after subtracting 164.
= 86 cups
Therefore, number of cups remaining are 86 cups.

Answer:

Step-by-step explanation:
first, you can say that QRP is similar to PRS
with the ratios, you can say that
[tex]\frac{QR}{PR} = \frac{PR}{RS}\\[/tex]
by substituting values, you have
[tex]\frac{6}{PR} = \frac{PR}{18}\\[/tex]

[tex]PR=6\sqrt{3}[/tex]
using pythagorean theorem, you can determine that

Step-by-step explanation:
S.P. (Selling Price) is the price at which a product is sold. C.P. (Cost Price) is the price at which a product is purchased. When S.P. is greater than C.P., it results in a profit. To calculate profit, the formula is simple:
Profit = S.P. - C.P.
In this case, S.P. is Rs. 210 and C.P. is Rs. 190. So, the profit would be calculated as:
Profit = Rs. 210 - Rs. 190 = Rs. 20.

Cosine functions can also be used as the foundation for sinusoidal functions because they are essentially a horizontal shift of sine functions.
We must establish the amplitude, period, and vertical shift of the periodic phenomenon in order to establish a sinusoidal function that models it. Determining whether to utilize a sine or a cosine function and the ensuing phase shift is also necessary.

where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Given data ,
Let the probability be represented as P
The total number of trials n = 5
The probability of getting a success p = 0.70
The probability of getting a failure q = 0.30
Now , the equation will be
a)
The probability that the player makes exactly 3 of the 5 shots = A
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
n = 5
x = 3
Substituting the values in the equation , we get
A = ⁵C₃ ( 0.70 )³ ( 0.30 )²
A = 10 ( 0.343 ) ( 0.09 )
A = 0.3087
So , probability that the player makes exactly 3 of the 5 shots is 0.3087
b)
The probability that the player makes exactly 4 of the 5 shots = B
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
n = 5
x = 4
Substituting the values in the equation , we get
B = ⁵C₄ ( 0.70 )⁴ ( 0.30 )¹
B = 5 ( 0.2401 ) ( 0.3 )
B = 0.36015
So , probability that the player makes exactly 4 of the 5 shots is 0.36015
c)
The probability that the player makes all 5 shots = C
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
n = 5
x = 5
Substituting the values in the equation , we get
C = ⁵C₅ ( 0.70 )⁵ ( 0.30 )⁰
C = 0.16807
So , probability that the player makes all 5 shots is 0.16807
d)
The probability that the player makes 3 or 4 of the shots = D
D = A + B
D = 0.3087 + 0.36015
D = 0.66885
Hence , the probability is solved
