The dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is 75 square meters

What is measurement?

Measurement is the process of assigning numerical values to physical quantities, such as length, mass, time, temperature, and volume, in order to describe and quantify the properties of objects and phenomena.

Let's assume that the rock wall is the width of the garden and the wire fencing is used for the length and the other two sides. Let's denote the length of the garden as L and the width as W.

Since we have 30 meters of fencing available, the total length of wire fencing used is:

L + 2W = 30 - W

Simplifying this equation, we get:

L = 30 - 3W

The area of the garden is:

A = LW

Substituting the expression for L from the previous equation, we get:

A = W(30 - 3W)

Expanding the expression, we get:

A = 30W - 3W²

To find the maximum area, we need to take the derivative of A with respect to W and set it equal to zero:

dA/dW = 30 - 6W = 0

Solving for W, we get:

W = 5

Substituting this value back into the expression for L, we get:

L = 15

Therefore, the dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is:

A = 5(15) = 75 square meters

Based on simple interest, the solution to the question is that his friend will ultimately owe Darrel $2,875.

A loan or investment's interest can be calculated using simple interest using the principal, interest rate, and duration of the transaction. Because it just considers the original principal and does not account for any compounded interest, it is known as "simple" interest.

Darrel will be indebted to his friend for the following sum if he lends him $2,500 and receives repayment with 15% simple interest after a year:

Interest = Principal x Rate x Time

Interest = $2,500 x 0.15 x 1

Interest = $375

Thus, the total sum his friend will be required to pay Darrel is:

Total amount = Principal + Interest

Total amount = $2,500 + $375

Total amount = $2,875

Thus, the total amount his friend owes Darrel is $2,875.

Answer:

The height of the block is two-thirds of its width, so we have h = (2/3)x.

The length of the block is 4 times its height, so we have l = 4h = 4(2/3)x = (8/3)x.

The volume of the block is given by V = lwh, so substituting the values we have:

V = (8/3)x * x * (2/3)x = (16/81)x³

Therefore, the volume of the block is (16/81)x³ cubic cm.

Answer:

-3

Step-by-step explanation:

First, -7 minus 8 is -15.

-15 divided by 5 is -3.

therefore, the simplified answer is -3.

We need 30 liters of the 35% acid solution and 40 liters of the 70% acid solution.

The volume of each solution is calculated as follows;

Let x be the number of liters of the 35% acid solution

Let y be the number of liters of the 70% acid solution

x + y = 70 ----- (1)

0.35x + 0.70y = 0.55(70) ----- (2)

The equation is simplified as;

0.35x + 0.70y = 38.5

from (1) x = 70 - y

Substitute x = 70 - y into equation 2:

0.35(70 - y) + 0.70y = 38.5

24.5 - 0.35y + 0.70y = 38.5

0.35y = 14

y = 40

Substitute y = 40 into equation 1 to solve for x:

x + 40 = 70

x = 30

Answer:

The following objects would most likely weigh 2 kilograms:

The actual weight of each object may vary, but based on typical weights, any of these objects could weigh around 2 kilograms.

Answer:

y =27/39x + 7

Step-by-step explanation:

Step 1: Calculating Slope (m).

m = y2-y1/x2-x1

m = (25)-(-2)/(26)-(-13)

m = 25+2/26+13

m = 27/39

m = 0.692

Now putting value of m in equation (i)

y = 0.692x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (-13,-2) for calculating y-intercept:

y = mx + b

-2 = 0.692(-13) + b

-2 = -9.00 + b

7 = b

b = 7

Now putting value of b in equation (ii)

y = 0.692x + 7

Note that the shape with with two parallel sides is called an irregular parallelogram. See the attached image.

The polygon  is an irregular quadrilateral because two sides are parallel lines and the other two sides are not.

Irregular polygons have infinitely many sides because their lengths are not equal. Shapes such as parallelograms, trapeziums, and quadrilaterals are irregular polygons because their neighboring sides and angles are not equal.

To find the equation of a line passing through a given point that is perpendicular to a given line, we need to follow these steps:

Find the slope of the given line by rearranging the equation into slope-intercept form y = mx + b, where m is the slope.

Find the slope of a line perpendicular to the given line by taking the negative reciprocal of the slope found in step 1.

Use the point-slope form y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope found in step 2, to write the equation of the perpendicular line.

Step 1: Find the slope of the given line 5x - 3y = 10

We can rearrange the equation into slope-intercept form by solving for y:

5x - 3y = 10

-3y = -5x + 10

y = (5/3)x - (10/3)

The slope of this line is 5/3.

Step 2: Find the slope of a line perpendicular to the given line

The slope of a line perpendicular to the given line is the negative reciprocal of 5/3:

m_perp = -3/5

Step 3: Use the point-slope form to write the equation of the perpendicular line passing through (-3, -7).

We plug in the values we found for the slope and the given point into the point-slope form:

y - y1 = m_perp(x - x1)

y - (-7) = (-3/5)(x - (-3))

Simplifying this equation, we get:

y + 7 = (-3/5)x - 9/5

Now we can rearrange this equation into slope-intercept form y = mx + b, where m is the slope and b is the y-intercept:

y = (-3/5)x - 44/5

Therefore, the equation of the line passing through the point (-3, -7) and perpendicular to the line 5x - 3y = 10 is y = (-3/5)x - 44/5.

Let's call the number of minutes of calls "x".

For the first plan, the cost will be:

Cost = $18 + $0.15x

For the second plan, the cost will be:

Cost = $12 + $0.20x

To find the point at which the costs of the two plans are equal, we can set the two equations equal to each other and solve for x:

$18 + $0.15x = $12 + $0.20x

Subtracting $12 from both sides, we get:

$6 + $0.15x = $0.20x

Subtracting $0.15x from both sides, we get:

$6 = $0.05x

Dividing both sides by $0.05, we get:

x = 120

Therefore, if a customer makes more than 120 minutes of calls per month, the first plan with the $18 monthly fee and $0.15 per minute charge will be more cost-effective. If a customer makes less than 120 minutes of calls per month, the second plan with the $12 monthly fee and $0.20 per minute charge will be more cost-effective.

Answer:

120 minutes

Step-by-step explanation:

Let x be the number of minutes of calls made in a month.

For the first plan, the monthly cost is $18 + $0.15x.

For the second plan, the monthly cost is $12 + $0.20x.

To find the point where the costs are equal, we need to solve the equation:

18 + 0.15x = 12 + 0.20x

Subtracting 0.15x from both sides gives:

18 = 12 + 0.05x

Subtracting 12 from both sides gives:

6 = 0.05xDividing both sides by 0.05 gives:

x = 120

Therefore, the costs of the two plans will be equal for 120 minutes of calls.

The value of the side x is 4. 36

a)she need 3.68 negative point , The new APR for Moira will be 3.25% + (3.68 x 0.135%) = 3.7452% because each negative point raises the APR by 0.135%.and the breakeven time for Moira's loan is 10 months

Breakeven time refers to the amount of time it takes for the savings from a particular action to equal the costs associated with that action. It is the point at which the benefits and costs are equal, and after which the benefits will begin to exceed the costs.

a. Moira has to buy 14,000/380,000 = 0.0368 or 3.68% in negative points to offset $14,000 in closing fees. The closing expenses are reduced by 1% of the principle for every negative point, therefore Moira has to buy 3.68/1 = 3.68 negative points.

b. The new APR for Moira will be 3.25% + (3.68 x 0.135%) = 3.7452% because each negative point raises the APR by 0.135%.

c.When the savings from buying the negative points equal the additional interest paid because of the higher APR, that is the breakeven point for Moira's loan. 3.68 x 380,000 x 1% = $14,040 is the savings from buying 3.68 negative points. The difference between the interest paid at the original APR of 3.25% and the interest paid at the new APR of 3.7452% represents the additional interest paid as a result of the higher APR. A 10-year, $380,000 mortgage at 3.25% would have a monthly payment of $3,680.97 according to an online mortgage calculator. During a period of ten years, interest payments total $73,276.23. A 10-year, $380,000 mortgage at 3.7452% has a $3,918.23 monthly payment. Throughout a ten-year period, interest was paid a total of $88,668.83. The additional interest paid as a result of the higher APR equals $15,392.60 ($88,668.83 x $73,276.23). The breakeven point is therefore $14,040/$15,392.60 = 0.910 or roughly 10 months.
