As It takes Sara 1/2 day to make a birdhouse, the number of birdhouse which will be built after 2/5 day is 4/5 of a birdhouse.

Since it takes Sara 1/2 day to make a birdhouse, we can say that she can make 2 birdhouses in one day.

So, after 1/2 day, Sara will complete 1 birdhouse.

Now, let's see how much of the birdhouse Sara can build after 2/5 day:

2/5 day is equivalent to (2/5) x (1/2) = 1/5 day.

Since Sara can build 1 birdhouse in 1/2 day, she can build 1/2 of a birdhouse in 1/4 day (half of 1/2 day).

Therefore, in 1/5 day, she can build:

= (1/5) / (1/4)

= (1/5) x (4/1)

= 4/5 of a birdhouse.

Step-by-step explanation:

The company will need 3,583.2 square inches of paper to make 15 labels.

What is cylinder?

Traditionally, a cylinder was a three-dimensional solid, one of the most fundamental curvilinear geometric shapes. It is a prism with a circle as its base in elementary geometry.

The formula for circumference is:

Circumference = π × diameter

Circumference = 3.14 × 8in

Circumference = 25.12in

So the label will need to be 25.12 inches long.

The height of the label will be the same as the height of the can, which is 9 inches.

To find the total area of the paper needed for 15 labels, we need to multiply the length of each label by its height and then multiply that by the number of labels:

Total area = length × height × number of labels

Total area = 25.12in × 9in × 15

Total area = 3,583.2 square inches

Thus, the answer is 3,583.2 square inches.

Variable words are commonly used in complex algorithms to show consistency between two contradictory claims. Academic expressions called equations are used to show the equality of various academic numbers. Instead of another algorithm that can analyze data given by y + 7, split 12 to two parts, and produce y + 7, leveling produces b + 7 in this instance.

Here,

First, let's construct the solution utilizing the distance formula:

Walking distance plus cycling distance equals total distance.

Distance equals speed times time.

=> [(x+2)(x-3)] + [(3x+5)(x)] = 74

Simplifying and finding x's value:

=> x² - 4x - 9 + 3x² + 5x = 74

=> 4x² + x - 83 = 0

Making use of the quadratic formula:

=> x = [-1 + √(1 - 4(4)(-83))] / 8

=> x = [-1 ± √(1337)] / 8

=> x ≈ 4.11 or x ≈ -5.11

We can disregard the bad outcome because time cannot be negative.

Consequently,

=> x = 4.11.

Now that we know how long the full journey took, we can:

=> Time taken = x + (x-3)

=> Time spent = 2x - 3

=> Using x instead of 4.11:

=> Duration: 5.22 hours

The length of a rectangle cannot be negative, hence the length of the rectangle is 7 units.

Based on the question given, the width (W) is the length (L) minus 3 units, which can be expressed as:

W = L - 3

The formula for the area (A) of a rectangle is:

A = Length × Width

We are given that the area is 28 square units, so:

A = 28

Now, we can substitute the expressions for width (W) and area (A) into the area formula:

28 = L × (L - 3)

Now, we need to solve this quadratic equation for L. First, expand the equation:

28 = L^2 - 3L

Now, rearrange the equation in standard quadratic form

L^2 - 3L - 28 = 0

To solve this quadratic equation, you can factor it:

(L - 7)(L + 4) = 0

Now, set each factor equal to zero and solve for L:

L - 7 = 0

L = 7

L + 4 = 0

L = -4

Since the length of a rectangle cannot be negative, hence the length of the rectangle is 7 units.

Step-by-step explanation:

The shape in the picture is an isosceles triangle. This is determined because two sides share the same length. This will mean that two angles will also share the same measurement, helping us to find our answer.

Step 2: Write an equation

Now that we have identified the type of triangle, we can write an equation to solve. Two angles will be equal to 70, so subtract 70 twice from 180. It will be taken away from 180, since in a triangle the three angles are equal to 180 degrees. Now we can write the equation!

X= 180-70-70

Step 3: Solve for ∠x

The final step will be to solve using the equation we have created before.

X= 180-70-70

X= 110-70

X= 40

To find how long it will take for Francine's money to grow to $7,500, we can set up the equation:

7500 = 5000(1.005)^(12t)

where t is the number of years. We want to solve for t.

First, divide both sides by 5000:

1.5 = (1.005)^(12t)

Next, take the natural logarithm of both sides:

ln(1.5) = ln(1.005)^(12t)

Using the rule of logarithms that ln(a^b) = b ln(a), we can simplify the right side:

ln(1.5) = 12t ln(1.005)

Finally, divide both sides by 12 ln(1.005):

t = ln(1.5)/(12 ln(1.005))

Using a calculator, we get:

t ≈ 14.6 years

Therefore, it will take about 14.6 years for Francine's money to grow to $7,500.

Anna needs to pay N$8,500 + N$1,062.50 = N$9,562.50 in two and a half years from now to meet her obligation.

What is Simple interest?

Simple interest is a type of interest that is calculated based only on the principal amount of a loan or investment. It is a fixed percentage of the principal that is charged for the use of money over a specified period of time.

First, let's calculate the interest on the loan for three and a half years.

Interest = Principal * Rate * Time

where the principal is N$20,000, the rate is 5%, and the time is 3.5 years.

Interest = 20,000 * 0.05 * 3.5 = N$3,500

So Anna owes N$20,000 + N$3,500 = N$23,500 in total at maturity.

Next, let's subtract the payments Anna plans to make from the total amount she owes to find out how much she still needs to pay:

N$23,500 - N$8,000 (planned payment) - N$2,000 (planned payment) - N$5,000 (planned payment) = N$8,500

So Anna still needs to pay N$8,500 to meet her obligation.

Finally, we need to calculate how much she should pay in two and a half years from now. We can use the simple interest formula again, this time with a principal of N$8,500, a rate of 5%, and a time of 2.5 years.

Interest = Principal * Rate * Time

Interest = 8,500 * 0.05 * 2.5 = N$1,062.50

So Anna needs to pay N$8,500 + N$1,062.50 = N$9,562.50 in two and a half years from now to meet her obligation.

Answer:

a) The surface area of a cuboid is given by the formula:

SA = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the cuboid, respectively.

In this case, we are given that:

h = xem

w = 2h = 2xem

l = 3h = 3xem

Substituting these values into the formula for the surface area of a cuboid, we get:

SA = 2(3xem)(2xem) + 2(3xem)(xem) + 2(2xem)(xem)

= 12xem^2

Therefore, the formula for the surface area of this cuboid is SA = 12xem^2.

b) Using the formula SA = 12xem^2, we can calculate the surface area of each cuboid and then add them to find the total surface area.

For cuboid A, x = 3, so the surface area is:

SA(A) = 12(3em)^2

= 108em^2

For cuboid B, x = 5, so the surface area is:

SA(B) = 12(5em)^2

= 300em^2

Therefore, the total surface area of the two cuboids is:

SA(A+B) = SA(A) + SA(B)

= 108em^2 + 300em^2

= 408em^2

So the total surface area of the two cuboids is 408em^2.

Answer:

Step-by-step explanation:

Alan made an error in assuming that the distance between -8 and 3 on the x-axis is the same as the distance between -8 and the y-axis, and between 3 and the y-axis. This is not necessarily true, as the distance between two points on a coordinate plane is given by the Pythagorean theorem:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Using this formula, we can find the actual distance between points A and B:

distance = sqrt((3 - (-8))^2 + (-4 - (-4))^2)

distance = sqrt(11^2 + 0^2)

distance = sqrt(121)

distance = 11

So the actual distance between points A and B is 11 units.

Therefore, Alan's error was assuming that the distance between A and B is simply the difference in the x-coordinates, which is not the case.

The sum of the first 19 terms of the arithmetic sequence 2, 3, 4, 5, ... is 209.

To find the sum of the first 19 terms of the arithmetic sequence 2, 3, 4, 5, ..., we need to use the formula for the sum of an arithmetic sequence:

Sₙ = n/2 (a₁ + aₙ)

where Sₙ is the sum of the first n terms of the sequence, a₁ is the first term of the sequence, aₙ is the nth term of the sequence, and n is the number of terms we want to sum.

In this case, a₁ = 2 (the first term of the sequence), aₙ = 2 + (n - 1) = n + 1 (the nth term of the sequence), and n = 19 (we want to sum the first 19 terms of the sequence).

Therefore, we can plug these values into the formula and get:

S₁₉ = 19/2 ˣ (2 + 19 + 1)

     Now, we will find change in y over change in x (the slope).

               [tex]\displaystyle \frac{-12-0}{0-8}=\frac{-12}{-8} =\frac{3}{2}[/tex]

     Lastly, we can write our equation using the slope and y-intercept.

               y = [tex]\frac{3}{2}[/tex]x - 12

Answer:

y = 3/2x - 12

Step-by-step explanation:

X-intercept located at (8,0)

Y-intercept located at (0, -12)

The equation is y = mx + b

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

2 points (8,0) (0, -12)

We see the y decrease by 12 and the x decrease by 8, so the slope is

m = -12 / -8 = 3/2

Y-intercept is = -12

So, the equation is y = 3/2x - 12
