A farmer has a 420 acre farm. He planted 7/12 of it with corn, but later found that 3/14 of the crop was diseases. How many acres of healthy corn did the farmer have
Answer:
192.5 acres.
Step-by-step explanation:
Total area of farm the farmer had = 420 acre.
Of these he did not plant full but only 7/12th of the total acres.
Planted area with corn = 7/12(420) = 245 acres
Of these 245 acres, 3/14th was affected by crop and the remaining part would be healthy
crop affected by disease = 3/14 (245) = 52.5 acres
Hence healthy corns = area planted for corn-diseased part of area
=245-52.5
= 192.5 acres
paralell to y=4x-6 through (12,10)
ANSWER
The line that is parallel to [tex]y=4x-6[/tex] through [tex](12,10)[/tex] is [tex]y=2x-14[/tex].
EXPLANATION
The equation that is parallel to the line [tex]y=4x-6[/tex] has a slope that is equal to the slope of this line.
By comparing this equation to the general slope intercept form,
[tex]y=mx+c[/tex],this line has slope [tex]m=2[/tex].
Hence the line parallel to this line also has slope [tex]m=2[/tex].
Let [tex]y=mx+b[/tex] be the equation of the line parallel to the line
[tex]y=4x-6[/tex]
We can substitute [tex]m=2[/tex] to obtain;
[tex]y=2x+b[/tex]
If the line passes through the point [tex](12,10)[/tex],then this point must satisfy its equation.
We substitute [tex]x=12[/tex] and [tex]y=10[/tex] to obtain;
[tex]10=2(12)+b[/tex]
We this equation for [tex]b[/tex].
[tex]\Rightarrow 10=24+b[/tex]
[tex]\Rightarrow 10-24=b[/tex]
[tex]\Rightarrow -14=b[/tex]
We substitute this value of [tex]b=-14[/tex] in to [tex]y=2x+b[/tex] to get;
[tex]y=2x+-14[/tex].
Hence the equation of the line that is parallel to [tex]y=4x-6[/tex] through [tex](12,10)[/tex] is [tex]y=2x-14[/tex].

A prism's volume is given by the expression
6k2 – 13k + 5. The area of the base of the
prism is 2k – 1.
Which expression represents the height of the prism?
k + 4
3k – 5
3k – 8 +
4k – 7 –
The volume of any prisma no matter wich one side it have got the following formula:
V=Ab*h where Ab is the base area and h is called height.
From our data we know the volume (6k^2-13K+5) and we know the base area (2k-1). Inserting this data in the general formula we got:
6k^2-13K+5=(2k-1)*h, solving for our unknown variable the height h
h=6k^2-13K+5/2k-1
factoring numerator :
h=(3k-5)(2k-1)/2k-1 simplifying
h=3k-5
The answer is 3k-5
Remark
The Volume = B * h
V = 6k^2 - 13k + 5
B = 2k - 1
h = ??
The volume will factor into (2k - 1)(3k - 5)
You can tell that one of the factors is 2k - 1 because that is the given amount for the base. You need only find the other factor. 3k is needed to multiply 2k to 6k^2.
- 1 needs - 5 to get the answer to 5
So the other factor is 3k - 5
Solution
V/b = h
(6k^2 - 13k + 5)/(2k - 1)
(3k - 5)(2k - 1) / (2k - 1) The (2k - 1)s Cancel out
Answer
B = 3k - 5 Second one down.
Domain of the function of a graph with coordinates (-3,-2)
Answer:
Domain is -3
Step-by-step explanation:
Given that coordinate of a graph is (-3, -2)
We have to find out the domain.
We know that if A and B are two sets, a mapping from A to B is the subset of cartesian product AxB.
Domain is the set of values of A which have images in B.
Use the above definition.
We have A = {-3,...} and B = {-2,....}
The mapping is from -3 to -2
Hence domain is -3

a new PlayStation costs $358.20 plus VAT. VAT is charged at 17.5% how much is paid for the new PlayStation?
$358.20 + $358.20 * 17.5% = $420.89
$358 -- Original Price
$358.20 * 17.5% -- Price of Tax
$358.20 + $358.20 * 17.5% -- Both added together
The total cost of the new PlayStation is calculated by adding the initial price ($358.20) and the VAT amount at a rate of 17.5%. The VAT amounts to $62.68. Hence, the total amount paid for the new PlayStation is $420.88.
Explanation:The total cost of the new PlayStation includes the initial cost and the additional charge due to VAT (Value Added Tax). Here, the initial cost is $358.20 and the VAT is charged at 17.5%. First, we need to calculate the VAT amount.
The VAT amount can be calculated using the formula:
VAT Amount = (VAT rate/100) x Cost without VAT
So, VAT Amount = (17.5/100) x 358.20 = $62.68
Now, we can calculate the total cost including VAT. The total cost including VAT is the sum of the initial cost and the VAT amount, which in this case is:
Total cost = Initial cost + VAT Amount
So, Total cost = 358.20 + 62.68 = $420.88
Therefore, the amount paid for the new PlayStation, taking into account the VAT, is $420.88.

In an arithmetic sequence, find a6 when a1 = 13 and d = 4
[tex]a_{6}[/tex] = 33
the n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1 )d, hence
[tex]a_{6}[/tex] = 13 + (5 × 4 ) = 13 + 20 = 33
The sixth term (a₆) is 33 in the arithmetic sequence.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
The formula to find the general term of an arithmetic sequence is,
aₙ = a₁ + (n-1)d
In arithmetic, sequence d represents the common difference.
Where aₙ is the nth term of the sequence and a₁ is the first term
We have been given that a₁ = 13 and d = 4 in an arithmetic sequence,
Substitute the values in the formula,
⇒ a₆ = 13 + (5 × 4)
⇒ a₆ = 13 + 20
⇒ a₆ = 33
Therefore, the sixth term is 33 in the arithmetic sequence.

The perimeter of a square is 3 4/5 meters.what is the area?
3 4/5 = 4l
A = l^2
Divide 3 4/5 by 4.
l = 0.95
0.95^2 = 0.9025
The area of the square is 0.9025 meters.
To find the area of a square with a perimeter of 3 4/5 meters, we first convert the perimeter to an improper fraction, divide by 4 to find the length of one side, and then square this length to get the area, resulting in 361/400 square meters.
Explanation:The question is asking us to find the area of a square when the perimeter is given as 3 4/5 meters. First, we convert the mixed number to an improper fraction which is (3 × 5 + 4)/5 = 19/5 meters. Since the perimeter of a square is the sum of all its sides (P = 4a), we can find the length of one side (a) by dividing the perimeter by 4.
a = P / 4 = (19/5) / 4 = 19/20 meters.
Now that we have the length of a side, we can find the area by squaring this length:
Area = a · a = (19/20) · (19/20) = 361/400 square meters.
Therefore, the area of the square is 361/400 square meters.

The cost of driving a car includes both fixed costs and mileage cost. Assume that a costs $176.10 per month for insurance and car payments and $0.25 per mile for gasoline, oil, and routine maintenance.
$176.10 per month for insurance and car payments and $0.25 per mile for gasoline, oil, and routine maintenance.
(a) find values for m and b so that y=mx+b Modells the monthly cost of driving the car X miles
(B) what does the value of b represents ?
Y=.25x+176.10 Y is the monthly cost and B would be the cost of the insurance every month. X is the amount of miles driven since the .25 stays constant but the amount of miles you drive in a month is different every month, Hence, needs to be a variable that can be adjusted,
A - The value of b, $176.10, represents the fixed costs like insurance and car payments, which remain constant regardless of the number of miles driven. B - It serves as the baseline monthly cost for driving the car.
(a) To model the monthly cost of driving the car (y) in terms of the number of miles driven (x), you can use the equation y = mx + b, where:
y represents the monthly cost of driving the car.
x represents the number of miles driven.
m represents the cost per mile for gasoline, oil, and routine maintenance, which is $0.25 in this case.
b represents the fixed costs, including insurance and car payments, which are $176.10 per month.
So, the values for m and b in this scenario are:
m = 0.25 (the cost per mile)
b = 176.10 (the fixed monthly costs)
Therefore, the equation to model the monthly cost of driving the car is:
y = 0.25x + 176.10
(b) The value of b, which is 176.10 in this equation, represents the fixed costs associated with driving the car. In this case, it includes the monthly insurance and car payment expenses. These are costs that do not depend on how many miles you drive.
Instead, they remain constant every month. So, b represents the baseline or starting point for the monthly cost of driving the car. Even if you were to drive zero miles in a month, you would still have to pay these fixed costs.

A honeydew melon costs four times as much as a peach. Together they cost $1.50. How much does each cost
Answer:
Cost of peach = 0.30$
Cost of honeydew melon = 1.20$
Explanation:
Let us assume that cost of peach to be x.
So we have cost for the honeydew melon = Four times of the cost of peach
= 4x
Total cost = Cost of honeydew melon + Cost of peach
= 4x+x = 5x
We also have total cost = $1.50
So equating both
5x = $1.50
x = 1.50/5 =0.30$
So cost of peach = 0.30$
Cost of honeydew melon = 4x = 4*0.30 = 1.20$
im thinking of a number. My number is 5 more then one-half my number. Create an equation based on this situation to find my number.
The equation which represent the number you are thinking x = (1/2)x + 5 your number is 10.
Let's represent the number you are thinking of as "x."
According to the given information, your number is 5 more than one-half of your number. Mathematically, this can be written as:
x = (1/2)x + 5
The equation x = (1/2)x + 5 represents the situation where your number is 5 more than one-half of your number. To find the value of your number (x), you can solve this equation:
Subtract (1/2)x from both sides to isolate x:
x - (1/2)x = (1/2)x + 5 - (1/2)x
(1/2)x = 5
Now, multiply both sides by 2 to get rid of the fraction:
2 * (1/2)x = 2 * 5
x = 10
