Andy is buying a car. He negotiated a 7% on a £6500 car. He will pay the full balance in 12 equal monthly payments.
Calculate the amount paid each month.
9514 1404 393
Answer:
£562.42
Step-by-step explanation:
Payments on a loan of P at rate r for n months can be found from ...
A = P(r/12)/(1 -(1 +r/12)^-n)
For r = .07 and n = 12, the payments on a £6500 loan will be ...
A = £6500(.07/12)/(1 -(1 +.07/12)^-12) = £562.42
Andy will pay £562.42 each month.

Convert 0.04 to a fraction in lowest terms. *
Answer:
1/25
Step-by-step explanation:
0.04 = 4/100 = 1/25
Answer:
[tex]\frac{1}{25}[/tex]
Step-by-step explanation:
0.04 is equal to [tex]\frac{4}{100}[/tex]. You can simplify this when both the numerator (the top number of the fraction) and the denominator (the bottom number of the fraction) can be divided by the same number. In this case, both numbers can be divided by 4, which would simplify it to its lowest form: [tex]\frac{1}{25}[/tex].

the area of a circle is 144 π cm2 what is the diameter of the circle
Step-by-step explanation:
Area = pi × r²
144 pi cm² = pi × r²
144 pi ÷ pi = r 2
root 144 = r
12 cm = r
diameter = 2r = 2(12) = 24 cm

Clare made an error when solving – 4x + 3 < 23.
Describe the error that she made.
- 4x + 3 =23
- 4x < 20
Step-by-step explanation:
-4x + 3 < 23
-4x < 20
x > -5
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating.
we can just keep the question as it is and calculate.
The error Clare made in solving the inequality -4x + 3 < 23 is in the last step. The correct solution should be x > -5, not x < -5.
When dividing or multiplying both sides of an inequality by a negative number, the direction of the inequality symbol should be flipped. In this case, since we are dividing by -4, which is negative, the inequality should be reversed.
The correct steps to solve the inequality are as follows:
-4x + 3 < 23
Subtract 3 from both sides:
-4x < 20
Divide both sides by -4 (remembering to flip the inequality symbol):
x > -5
Therefore, the correct solution is x > -5, indicating that x is greater than -5, not less than -5 as Clare mistakenly wrote.

John is mixing paint so that he can update his apartment. He combines 7L of white paint with 3300 milliliters of blue paint. He uses 1 ½ L of paint to paint a hallway. a) What is the total combined paint? b) How much paint was left after painting? 4.
Answer:
(a) The total combined paint is 10.3L
(b) 8.8L paint was left after painting
Step-by-step explanation:
From the question, John combines 7L of white paint with 3300 milliliters of blue paint.
First, convert to the same unit, say liters, L.
Now, we will convert 3300 milliliters to liters (L)
{NOTE: 1000 milliliters (mL) = 1 liter (L)}
Since 1000 milliliters = 1 liter
∴ 3300 milliliters = 3300/1000 liters = 3.3 liters
Hence, 3300 milliliters = 3.3 L
Therefore, he combines 7L of white paint with 3.3L of blue paint.
(a) The total combined paint is 7L + 3.3L = 10.3L
∴ The total combined paint is 10.3L
(b) To determine how much paint was left after painting,
From the question, he uses 1 ½ L of paint to paint a hallway, that is, he uses 1.5 L of paint to paint a hallway;
The paint left will be 10.3L - 1.5L
10.3L - 1.5L = 8.8L
Hence, 8.8L paint was left after painting
Which is true of the slopes of parallel lines
Answer: slopes will be the same!
Step-by-step explanation:
Answer:
In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other. Here is a quick review of the slope/intercept form of a line

Ibai has taken 2/5 out of a barrel of beer, Ane has drawn a third. It expresses in graphic and numerical form: a) The fraction that they have drawn between the two. b) Which of them has gotten the most?
Answer:
7/15
Step-by-step explanation:
2/5 + 1/3 is the same as 2/5 + 5/15.. so we add them together to get 7/15. This can not be simplified further
To know who has gotten most I like to think in percentage terms. 2/5 is the same as 40% (2/5 is the same as 4/10 = 40/100 =40%). 1/3 is 33.33% so Ane got more
Answer:
A. 11/15 B. Ibai.
Step-by-step explanation:
First, find the Least Common Multiple, or LCM, of the denominators, which is 15. Then, multiply each denominator by the number that gets the denominator to 15, which is the LCM. Next, multiply the numerator by the same number you multiplied the denominators, which was 3 for Ibai, and 5 for Ane. Finally, compare the two numbers to see which is higher. In this case, Ibai took out 6/15, while Ane took out 5/15, meaning Ibai took out more than Ane. Also, together, Ibai and Ane both drew out 11/15 together.
Sue wants to put a rectangular garden on her property using 88 meters of fencing. There is a river that runs through her property so she decides to increase the size of the garden by using the river as one side of the rectangle. (Fencing is then needed only on the other three sides.) Let x represent the length of the side of the rectangle along the river. Express the garden's area as a function of x. what is the largest area that can be enclosed?
Answer:
Area = 44x - x²/2
Step-by-step explanation:
Given that:
Meter of fencing = 88m
Length of side of rectangle along the river = x
Only one more length is needed since river as been used as one side length of the fence.
Length = x
Width of rectangle = y = 2y (for both sides)
Hence ;
x + 2y = 88 meters
Expressing in terms of y
2y = 88 - x
y = (88 - x) / 2
y = 44 - x/2
Area of rectangle = Length * width
Area = x * y
Area = x * (44 - x/2)
Area = 44x - x²/2
Maximum. Area :
Perimeter = 4s
88 = 4s
s = 88/4 = 22
x = 2(22) = 44 = Length ; y = 22 = width
Maximum area = (22 * 44) = 968m²
