Median MH is 6 units longer than median KP triangle GHI is similar to triangle JKL. If GH:JK=7:5, find the length of KP
Answers
Then HM/KP = 7/5.But we are given that HM = KP+6, so:
(KP+6)/KP =7/5. Now cross multiplication:
5(KP+6) = 7KP
5KP + 30 = 7KP
30 = 2KP and KP = 15
Answer: KP=15
Step-by-step explanation:
HM/KP = 7/5.
HM = KP+6, so:
(KP+6)/KP =7/5.
cross multiply
5(KP+6) = 7KP
5KP + 30 = 7KP
30 = 2KP and KP = 15

Charlie cannot remember how much he financed to buy his car. He does remember that his monthly payment is $200. His add-on interest rate was 9% and he made a total of 30 payments. Find the amount of his loan to the nearest penny.
Answers
Total paid
200×30=6,000 (this is the future value)
Second use the formula of the future value of annuity ordinary to find the monthly payment.
The formula is
Fv=pmt [(1+r/k)^(n)-1)÷(r/k)]
We need to solve for pmt
PMT=Fv÷[(1+r/k)^(n)-1)÷(r/k)]
PMT monthly payment?
Fv future value 6000
R interest rate 0.09
K compounded monthly 12
N=kt=12×(30months/12months)=30
PMT=6000÷(((1+0.09÷12)^(30)
−1)÷(0.09÷12))
=179.09 (this is the monthly payment)
Now use the formula of the present value of annuity ordinary to find the amount of his loan.
The formula is
Pv=pmt [(1-(1+r/k)^(-n))÷(r/k)]
Pv present value or the amount of his loan?
PMT monthly payment 179.09
R interest rate 0.09
N 30
K compounded monthly 12
Pv=179.09×((1−(1+0.09÷12)^(
−30))÷(0.09÷12))
=4,795.15
The answer is 4795.15
The initial amount that Charlie financed to buy his car is approximately $5,364.93. This was calculated using the add-on interest loan formula with the provided monthly payments, interest rates, and number of payments.
Explanation:The question is asking us to find out the initial amount that Charlie financed to buy his car, given that he made monthly payments of $200 at an interest rate of 9% over a total of 30 payments. This is a simple interest loan problem in mathematics, specifically dealing with add-on interest. To determine the original loan amount, we will use the formula for calculating the loan amount in an add-on interest loan. It is calculated by dividing the amount paid in total by the sum of one plus the product of the rate and time: Loan Amount = Total Payment / (1 + (Interest Rate * Time)) .
In this case, the total repayment made by Charlie is $200 * 30 = $6,000. The interest rate is 9% per year, but since he is making monthly payments we need to divide this by 12 to get the monthly interest rate, which is 0.0075. The time is 30 months. Substituting these values into our formula gives: Loan Amount = 6,000 / (1 + (0.0075 * 30)).
Hence, after calculations, the initial amount that Charlie financed to buy his car is approximately $5,364.93.

An amount of $3000 is deposited for one year at an interest rate of 5.5% per annum. How much interest will be earned?
Answers
Answer:
$165
Step-by-step explanation:
In 1 years, you will have $165.00 of simple interest.
Calculations: The Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods. Where r is in decimal form; r=R/100; r and t are in the same units of time.
The accrued amount of an investment is the original principal P plus the accumulated simple interest, I = Prt, therefore we have:
A = P + I = P + (Prt), and finally A = P(1 + rt)
Calculate Total Amount Accrued (Principal + Interest), solve for A
A = P(1 + rt)
Calculate Principal Amount, solve for P
P = A / (1 + rt)
Calculate rate of interest in decimal, solve for r
r = (1/t)(A/P - 1)
Calculate rate of interest in percent
R = r * 100
Calculate time, solve for t
t = (1/r)(A/P - 1)
Final answer:
The simple interest earned on a $3000 deposit at a 5.5% annual interest rate for one year is $165. This is found using the simple interest formula: Interest = Principal x Rate x Time.
Explanation:
To calculate the amount of simple interest earned on a $3000 deposit at an interest rate of 5.5% per annum for one year, we use the simple interest formula: Interest = Principal x Rate x Time.
In this case:
Principal (P) is $3000,
Rate (R) is 5.5% per annum, or 0.055 when expressed as a decimal,
Time (T) is 1 year.
So, the interest earned can be calculated as follows:
Interest = $3000 x 0.055 x 1
Interest = $165
Therefore, the amount of simple interest earned on the $3000 deposit after one year is $165.

Answers
The annual compounding rate is r = 5.13% = 0.0513.
The duration is n = 6 years.
The target amount is A = $24,388.
Use the formula
[tex]A=P(1+ \frac{r}{n} )^{nt} [/tex]
The value of the account after 6 years is
[tex]A=P(1+ \frac{0.0513}{12} )^{12\times6}=P(1.00428^{72})=1.3595P[/tex]
Therefore,
1.3595P = 24388

At the pie eating contest, Max ate 2⁄5 of a pie and Jen ate 6⁄8 of a pie. How many pies did they eat all together?
Answers
Max and Jen ate a total of 1 3/20 pies together.
Explanation:To find out how many pies Max and Jen ate all together, we need to add the fractions of the pies that each of them ate.
Max ate 2/5 of a pie and Jen ate 6/8 of a pie. To add these fractions, we need to find a common denominator. The common denominator of 5 and 8 is 40.
Multiplying the numerator and denominator of 2/5 by 8, we get 16/40. Multiplying the numerator and denominator of 6/8 by 5, we get 30/40.
Now we can add the fractions: 16/40 + 30/40 = 46/40.
Since 46/40 is an improper fraction, we can simplify it to a mixed number by dividing the numerator by the denominator. 46 divided by 40 is 1 with a remainder of 6, so the mixed number is 1 6/40.
However, we can simplify the fractional part of the mixed number further. Both 6 and 40 are divisible by 2, so we can divide both the numerator and denominator by 2: 6 divided by 2 is 3, and 40 divided by 2 is 20. Therefore, the simplified mixed number is 1 3/20.
Therefore, Max and Jen ate a total of 1 3/20 pies together.
Final answer:
Max ate 2/5 of a pie and Jen ate 6/8 of a pie. The total is 1 and 6/40 pies.
Explanation:
To find out how many pies Max and Jen ate all together, we need to add the fractions of pies they each ate. Max ate 2/5 of a pie and Jen ate 6/8 of a pie. To add these fractions, we need to have a common denominator.
To find the common denominator, we can multiply the denominators together. In this case, the common denominator would be 5 * 8 = 40.
Now, we can convert both fractions to have a denominator of 40.
Max's fraction becomes 16/40 and Jen's fraction becomes 30/40.
Finally, we add the two fractions together:
16/40 + 30/40 = 46/40.
So, Max and Jen ate a total of 46/40 or 1 and 6/40 pies all together.
Combinations- how to show that 10C2=10C8
Answers
The most effective way to show that 10C2 = 10C8 is to solve for the values of each combination. To solve for the values, we have to make use of the combination formula:
nCr = n! / r! (n – r)!
where n is the total sample size and r is the selected sample size
Calculating the value of 10C2:
10C2 = 10! / [2! (10 – 2)!]
10C2 = 10! / (2! * 8!)
10C2 = 45
Calculating the value of 10C8:
10C8 = 10! / [8! (10 – 8)!]
10C8 = 10! / (8! * 2!)
10C8 = 45
Therefore,
10C2 = 10C8

On a baseball field, the pitcher’s mound is 60.5 feet from home plate. During practice, a batter hits a ball 195 feet at an angle of 32° to the right of the pitcher’s mound. An outfielder catches the ball and throws it to the pitcher. Approximately how far does the outfielder throw the ball?
Answers
The outfielder throws the ball approximately 168 ft to the pitcher.
Explanation:The outfielder throws the ball to the pitcher at an angle of 32° to the right of the pitcher's mound. To find the distance the outfielder throws the ball, we need to break down the component of the throw in the direction perpendicular to the path of the ball. This can be done by finding the horizontal component of the throw.
To find the horizontal component, we can use the equation:
horizontal component of throw = distance * cos(angle)
Substituting the given values, we have:
horizontal component of throw = 195 ft * cos(32°)
Calculating this, we find that the horizontal component of the throw is approximately 168 ft.

A roulette wheel contains the integers 1 through 36, 0, and 00. suppose that you spin the wheel 6 times and that each time you bet on a single number. what is the probability (rounded to the nearest hundredth) that you win on at least one bet?
Answers
The probability of not wining on any bet is independent of winning or not winning on any of the bets, so the combined probability is calculated as the product of each individual probability.
Each indivitual probability of not winning the is:
(number of not winning outcomes) / (number of possible outcomes) = 37 / 38.
Then, the combined probability of not winning the six times is: (1/38)*(37/38)*(37/38)*(37/38)*(37/38)*(37/38) =(37/38)^6
Therefore, the probability of winning at least one bet is:
