yes the length of the strawberry patch can be greater than 1 yard.

A rectangle is a quadrilateral with four sides and four right angles.

Given that Danah wants the area of her rectangular strawberry patch to be exactly 1 square yard.

We have to find out whether the length of the rectangular strawberry patch can have a value greater than 1.

Area of a rectangle = Length x Width.

The area of the rectangular strawberry patch is exactly 1 square yard.

Area  = 1 square yard

Length x Width = 1 square yard

To have the area of the rectangular strawberry patch be exactly 1 square yard.

We can have the following cases :

Case 1.

Length = 2 and Width = 0.5

Area = Length x Width = 2 x 0.5 = 1 square yard.

Case 2.

Length = 4 and width = 0.25

Area = Length x Width = 4 x 0.25 = 1 square yard.

Case 3.

Length = 8 and width = 0.125

Area = Length x Width = 8 x 0.125 = 1 square yard.

Case 4.

Length = 10 and width = 0.1

Area = Length x Width = 10 x 0.1 = 1 square yard.

We see that we can have the length as 2, 4, 8, and 20 in order to have an area of the rectangle as 1 square yard.

Hence, yes the length of the strawberry patch can be greater than 1 yard.

If the price of Stock A at 9 A.M. was ​15.69$. The number of hours the prices of the two stocks be the​ same is: 3.125  hours.

Stock A = 15.69 + 0.05h

Stock B = 16.19 - 0.11

So equate Stock A and Stock B

15.69 + 0.05h = 16.19h - 0.11h

Combine like terms

0.11h + 0.05h = 16.19 -15.69

0.16h = 0.5

Divide both side by 0.16h

h = 0.5/0.16

Step-by-step explanation:

No because the bike order does not meet the restrictions of[tex]4c+6a \le 120 \ \text{ and } \ 4c+4a \le 100\\\\[/tex]

===================================================

Explanation:

c = number of child bikes

a = number of adult bikes

Each child bike takes 4 hours to build. This means 4c represents the total time spent building all c number of child bikes. Eg: if c = 2, then 4c = 4*2 = 8 hours is spent total building these two child bikes.

Meanwhile, each adult bike takes 6 hours to build. That means 6a represents the total time spent building these subset of bikes.

The expression 4c+6a is the total time spent building all of the bikes, child and adult.

The company has 120 hours of building time. The total time (4c+6a) cannot exceed this 120 hour ceiling.

This is how we arrive at [tex]4c+6a \le 120[/tex] which is one of the constraints or restrictions.

------------------------------

Now onto the testing side of things.

Each child bike takes 4 hours to test. That gives us 4c.

Each adult bike takes 4 hours to test. We get 4a.

4c+4a = total testing time for all of the bikes

[tex]4c+4a \le 100[/tex] is the second restriction we place, since we have at most 100 hours of testing time total. We cannot exceed this.

------------------------------

To summarize so far:

Let's see if we can build c = 20 child bikes and a = 6 adult bikes

Plug this pair of values into the first inequality

[tex]4c+6a \le 120\\\\4*20+6*6 \le 120\\\\80+36 \le 120\\\\116 \le 120[/tex]

The last inequality is true, which means the inequality [tex]4c+6a \le 120[/tex] is also true for the values c = 20 and a = 6.

So far it looks like we can build these number of bikes.

But we need to check the other inequality.

[tex]4c+4a \le 100\\\\4*20+4*6 \le 100\\\\80+24 \le 100\\\\104 \le 100\\\\[/tex]

We run into a problem. The last inequality is false, which means [tex]4c+4a \le 100[/tex] is false when c = 20 and a = 6 are plugged into it.

Meaning it is impossible to test 20 child bikes and 6 adult bikes in a week.

This is why   choice  A   is the final answer.

Using the concept of solving equation, (a) after four months, the total cost would be the same and (b) total cost for each club A and B are: 105.

Equations simultaneously, or a system of equations Multiple equations in algebra must be solved simultaneously. There must be an equal number of equations and unknowns for a system to have a singular solution. When two or more equations use the same variables, they are said to be in a system of equations. Graphing, substitution, and elimination are the three techniques used to solve systems of equations.

Let, x be the number of months of membership

y be the total cost

Club A : y = 20x + 25 ......... (i)

Club B : y = 23x + 13 ........... (ii)

Because we know that the prices, y would be equal, we can set the two equations equal to each other.

20x + 25 = 23x + 13

or, 3x = 12

or, x = 4

So, after four months, the total cost would be the same.

Total cost for each club A and B are: 105.

The perimeter of the triangle is  40.42 cm

The height of the triangle is 14 cm

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

The length of the base is 9.5 cm

The total area of the triangle is 66.5 cm²

We know,

Area = (1/2)*base * height

⇒ 66.5 = (1/2)*9.5* h

⇒h = 14 cm

The height is 14 cm

By using Pythagoras theorem  

hypotenuse = √{(base)² + (height)²} = √{(9.5)² + (14)²}  = 16.92 cm

The hypotenuse is 16.92 cm

The perimeter of the triangle is height + base + hypotenuse = 14 + 9.5 + 16.92 = 40.42 cm

a) The amount of the monthly mortgage payment is 843.86

b) The total amount of interest Ato Liku that will pay over the life of the mortgage is 104,000

c) The amount of the mortgage Ato Liku will have paid after 10 years is 101,263.20

a) To determine the amount of the monthly mortgage payment, we need to use the formula for the monthly mortgage payment (also known as the loan payment formula):

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]

where M is the monthly mortgage payment, P is the principal (the remaining balance after the down payment), i is the monthly interest rate (12%/12 = 1%), n is the number of payments (30 years x 12 months/year = 360 payments), and ^ denotes exponentiation.

P = 250,000 x (1-.20) = 200,000

n = 30 x 12 = 360

i = 0.12/12 = 0.01

M = 200,000 [ 0.01(1 + 0.01)^360 ] / [ (1 + 0.01)^360 - 1]

M = 843.86

b) To determine the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount (200,000) from the total amount of the payments over the life of the loan:

total interest = total payments - original loan amount

total payments = M x n = 843.86 x 360 = 304,000

total interest = 304,000 - 200,000 = 104,000

c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we need to multiply the monthly mortgage payment by the number of payments made after 10 years.

10 years x 12 months/year = 120 months

Mortgage paid after 10 years = 843.86 x 120 = 101,263.20

A pair of functions that are inverses of each other include the following: B. f(x) = 4x³ + 5 and g(x) = ∛[(x - 5)/4].

In order to determine the inverse of this function f(x) = -1 - 1/5x, we would interchange both the input value (x) and output value (y) as follows:

f(x) = y = ∛(x + 3) - 5

x = ∛(y + 3) - 5

x + 5 = ∛(y + 3)

Taking the cube of both sides of the function, we have:

(x + 5)³ = y + 3

g(x) = y = (x + 5)³ - 3 (Not an inverse of f(x)).

From the second answer option, we have the following:

f(x) = y = 4x³ + 5

x = 4y³ + 5

x - 5 = 4y³

Dividing both sides of the function by 4, we have the following:

y³ = (x - 5)/4
