Mr. Fitch needs to get a loan to replace the air-conditioning system in his home. The cost of the replacement, including installation, is $4,348.00. He can apply for a 5- year loan or a 3-year loan. Both loans involve simple interest with an annual interest rate of 6.5%. If Mr. Fitch applies for the 5-year loan, how much more will he pay in interest than with the 3-year loan? F. $704.98 G. $565.24 H. $2,260.96 J. $56,524.00
Answer: g
Step-by-step explanation:
4348x.065=282.62
282.62x5=1413.1
282.62x3=847.86
1413.1-847.86=565.24
Compared to a 3-year loan he has to pay G. $565.24 more for a 5-year loan.
What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, Mr. Fitch needs to get a loan to replace the air-conditioning system.
He can apply for a 5- year loan or a 3-year loan. Both loans involve simple interest with an annual interest rate of 6.5%.
Here, p = $4,348.00, r = 6.5%, t₃ = 3 and t₅ = 5.
For, t₃.
SI₃ = (4348×6.5×3)/100.
SI₃ = $847.86.
For, t₅.
SI₅ = (4348×6.5×5)/100.
SI₅ = $1,413.1.
So, the amount of interest he will have to pay more is (SI₅ - SI₃).
= $(1,413.1 - 847.86).
= $565.24.

GOODLUCKKKKKK3x^2 – 10x = 8
(it’s to the 2nd power btw)
Answer:
x = 4, (-2/3)
Step-by-step explanation:
3(x^2) – 10x = 8
3(x^2) – 10x - 8 = 0
(3x + 2)(x - 4) = 0
(3x + 2) = 0
3x = -2
x = (-2/3)
(x - 4) = 0
x = 4
Answer:
x = -2/3, 4
Step-by-step explanation:
move all terms to one side
3x^2 - 10x - 8 = 0
split the terms in 3x^2-10x-8 into two terms
3x^2+2x-12x-8=0
factor out common terms in first to and last to
x(3+2)-4(3x+2) =0
factor out common term 3x+2
(3x+2) (x-4)=0
solve for x
x=-2/3,4

Answer:
the three vertices are (1, 1), (2, 0), (-1, -3).
The vertices of the triangles are the coordinates of the point of
intersection of the graph of the equation of the three lines.
Correct response:
The coordinates of the three vertices of the triangles are;
E. [tex]\underline{(2, 0), \ (1, -1), \ and \ (-1, -3)}[/tex]
How are the coordinates of the vertices obtained?The equation of the given lines are;
y = -x + 2, y = 2·x - 1, y = x - 2
The point of the intersection of the two lines, gives the vertices, and are
the solution of the two linear equations of the lines.
At the points where the lines intersect, we have;
-x + 2 = 2·x - 1
Which gives;
3·x = 3
x = 1
y = -1 + 2 = -1
A vertex is at the point (1, -1)
The coordinate of the second vertex is given as follows;
2·x - 1 = x - 2
2·x - x = -2 + 1 = -1
x = -1
y = -1 - 2 = -3
The second vertex is; (-1, -3)
The coordinates of the third vertex is given as follows;
-x + 2 = x - 2
2·x = 4
x = 2
y = 2 - 2 = 0

To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below. StartFraction 6 Over 8 EndFraction divided by 6 = StartFraction (6 divided by 6) Over 8 EndFraction = one-eighth He concluded that each person received One-eighth of the whole pizza. Are Hernando's calculations correct? Explain why or why not. Yes, they are correct. Hernando divided 6 by 6. Yes, they are correct. Hernando divided Two-eighths by 6. No, they are not correct. Hernando should have multiplied by 6, not divided by 6. No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.
Answer:
Step-by-step explanation:
Hernando = 2/8
His 6 friends = 6/8
Total pizza = 2/8 + 6/8
= 8/8
Hernando's calculation
6/8 ÷ 6
= (6÷6) / 8

Answer:
1Step-by-step explanation:
Given the expression [tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1}[/tex]
According to indices:
[tex]a^{-1} = \frac{1}{a}[/tex]
Applying this to the question:
[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{1}\left\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right}[/tex]

A bag contains 15 marbles. The probability of randomly selecting a green marble is One-third. The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is StartFraction 1 over 15 EndFraction. What is the probability of randomly selecting a red marble
Answer:
1/5
Step-by-step explanation:
Total Number of Marbles in the bag = 15
The probability of randomly selecting a green marble is 1/3
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble = 1/15
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is calculated as
The probability of randomly selecting a green marble × The probability of randomly selecting a red marble
Hence:
1/15 = 1/3 × R
1/15 = R/3
Cross Multiply
R × 15 = 1 × 3
R= 3/15
R= 1/5
Hence, the probability of randomly selecting a red marble is 1/5

Step-by-step explanation:
A truck can be rented from Company A for $130 a day plus $0.60 per mile. Company B charges $70 a day plus $0.90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
200 miles
Step-by-step explanation:
Let's say that our variable is x, where x equals the amount of miles
Company A: a(x)=0.6x+130
Company B: b(x)=0.9x+70
For the first equation, you are charged 130 dollars, in addition to the 0.60 cents that you are charged per mile.
For the second equation, you are charged 70 dollars, in addition to the 0.90 cents that you are charged per mile.
You want to find how many miles it takes to make the two equations equal:
0.6x+130 = 0.9x+70 (Set them equal to each other because you are trying to find when the miles are equal and the cost is equal)
130=0.3x+70 (Subtract 0.6x from both sides)
60=0.3x (Subtract 70 from both sides)
x=200 (Divide both sides by 0.3 to find x)
Remember that x is the amount of miles, so, Company A and B would charge the same if you drove 200 miles.
Answer:I believe it’s 200 miles
Step-by-step explanation: let x represent the mileage you are trying to find and set the two equations equal to one another to find the mileage and which the rental cost would be the same.
130 + 0.60x = 70 + 0.90x
130-70 = 0.90x - 0.60x
60 = 0.30x
X= 60/0.03
X= 200 miles
