Working together, Maggie and Tom can paint the fence in 5.1 hours

Given that,

Maggie can paint a fence in 9 hours

So in 1 hour maggie paints, [tex]\frac{1}{9}[/tex] of the house

Tom needs 12 hours to paint the same fence

So in 1 hour, tom can paint [tex]\frac{1}{12}[/tex] of the house

To find: time taken to paint the fence if they work together

Let "a" be the time taken to paint the fence if they work together

So working together, in 1 hour, they can paint [tex]\frac{1}{a}[/tex] of the house

We can frame a equation as:

To see how much of the fence they can paint together in one hour, we add these together.

[tex]\frac{1}{9} + \frac{1}{12} = \frac{1}{a}[/tex]

[tex]\frac{1}{a}[/tex] is how much of the fence they can paint together in one hour.  Therefore "a" is the number of hours it will take them both to paint the fence

On solving,

[tex]\frac{12 + 9}{12 \times 9} = \frac{1}{a}\\\\\frac{1}{a} = \frac{21}{108}\\\\a = \frac{108}{21} = 5.1428[/tex]

So working together, Maggie and Tom can paint the fence in 5.1 hours

Ron's speed = 3 miles/hour

Stevie's speed = 2.5 miles/hour

On comparing we see Ron is walking faster than Stevie.

Step-by-step explanation:

Given:

Ron takes 10 minutes to walk on a track to cover a distance of 0.5 miles

Stevie takes 6 minutes to walk on a track to cover a distance of 0.25 miles

To find their unit rates in mile per hour and choose the faster one.

Solution:

Unit rate in miles per hour signifies their speeds. Thus, we will find out their speeds.

Ron:

Distance= 0.5 miles

Time = 10 minutes = [tex]10\ min\times \frac{1\ hr}{60\ min}=\frac{1}{6}[/tex] hours

Speed = [tex]\frac{Distance}{Time}=\frac{0.5}{\frac{1}{6}}=0.5\times6=3\ miles/hour[/tex]

Stevie

Distance = 0.25 miles

Time = 6 minutes = [tex]6\ min\times \frac{1\ hr}{60\ min}=\frac{1}{10}[/tex] hours

Speed = [tex]\frac{Distance}{Time}=\frac{0.25}{\frac{1}{10}}=0.25\times10=2.5\ miles/hour[/tex]

Thus, we have

Ron's speed = 3 miles/hour

Stevie's speed = 2.5 miles/hour

On comparing we see Ron is walking faster than Stevie.

Final answer:

To calculate the percentage of calories from fat, multiply the grams of fat by the calories per gram of fat and divide by the total calories consumed.

Explanation:

To calculate the percentage of calories from fat in Nadia's daily intake, we need to know the total number of calories she consumed. Let's assume it was 2000 calories. First, we calculate the number of calories from fat by multiplying the grams of fat consumed (60g) by the number of calories per gram of fat (9 calories/g). This gives us 540 calories from fat. Then, we calculate the percentage by dividing the calories from fat (540 calories) by the total calories consumed (2000 calories) and multiplying by 100. So, the percentage of calories from fat in Nadia's day's intake is 27%.

Answer:

C(x,y,z)=6*x*y+10*x*z+10*y*z

Step-by-step explanation:

Lets assume that x is width, y is length and z is height. To find the area of the top and bottom surfaces we need to simply multiply length and width.

x*y

There is a 2 surface exist (top and bottom) we need to multiply this value with 2 again.

2*x*y

and the cost is 3$ for per square foot and the cost for top and bottom is:

6*x*y$

Surface areas of side surfaces are multiply of width, height and length, height:

x*z+y*z

There are 4 side surfaces exist. Therefore the are need to be multiply with 2.

2*x*z+2*y*z

and the cost is 5$ for per square foot and the cost for side surfaces is:

10*x*z+10*y*z

Total equality for cost is C(x,y,z)=6*x*y+10*x*z+10*y*z

To calculate the cost of materials for a closed rectangular box, use the formulas C(x,y) = 2 * (3xy) for the top and bottom and C(z,y) = 2 * (5zy) for the sides. Then, find the total cost by adding the costs together.

To calculate the cost of materials for a closed rectangular box, we need to consider the dimensions of the box. Let's assume the dimensions are given as x, y, and z in feet.

The cost for the top and bottom parts of the box can be calculated using the formula C(x,y) = 2 * (3xy), where 3 is the cost per square foot and xy is the area of the top and bottom.

The cost for the side parts of the box can be calculated using the formula C(z,y) = 2 * (5zy), where 5 is the cost per square foot and zy is the area of the sides.

Finally, the total cost of materials for the box can be found by adding the costs for the top and bottom parts to the cost of the side parts: C(x,y,z) = C(x,y) + C(z,y).

Step-by-step explanation:

A rectangular lot whose perimeter is 260 ft is fenced along three sides. An expensive fencing along the​ lot's length cost $ 18per foot. An inexpensive fencing along the two side widths costs only $ 3per foot.

So we have

         l + 2 w = 260 -------------------eqn 1

And total cost is 1800 $

That is

                18 l + 2 x 3 w = 1800

                 3l + w = 300 -------------------eqn 2

eqn 2 x 2

                 6l + 2w = 600 -------------------eqn 3

eqn 3 - eqn 1

              6l + 2w - l - 2w = 600 - 260

                   5l = 340

                     l = 68 ft

Substituting in eqn 1        

                   68 + 2 w = 260    

                     2w = 192

                       w = 96 ft

Lot's dimension is 68 ft x 96 ft    

To calculate the expected number of applications that went to the right college, we need to consider the probability of each application being placed correctly. Since the applications are placed randomly, each application has an equal chance of going to the right college. The expected number of applications that went to the right college is 1.

To calculate the expected number of applications that went to the right college, we need to consider the probability of each application being placed correctly. Since the applications are placed randomly, each application has an equal chance of going to the right college. Let's say there are n applications and n colleges.

The probability of a specific application going to the right college is 1/n. Therefore, the expected number of applications that went to the right college can be calculated as:

Expected number = Total number of applications * Probability of an application going to the right college

Expected number = n * (1/n)

Expected number = 1

The expected number of applications that went to the right college is 1. This means that, on average, one application will go to the right college.

Answer:

C. $1.80

Step-by-step explanation:

Given:

MSRP of a certain item = $60

Percentage of Selling by store A = 20%

Percentage amount will be = [tex]\frac{20}{100}\times 60 = \$12[/tex]

Sales tax = 5% on purchase price

Amount of sales tax = [tex]\frac{5}{100}\times 60 = \$3[/tex]

Total Cost of item at Store A is MSRP of a certain item plus Percentage amount of selling the item plus Amount of Sales tax.

framing in equation form we get;

Total Cost of item at Store A = [tex]60+12+3 =\$75[/tex]

Also Given:

Percentage of Selling by store B = 30%

Percentage amount will be = [tex]\frac{30}{100}\times 60 = \$18[/tex]

Regular price of item at store B = [tex]60+18 = \$78[/tex]

Percentage of discount of item at store B = 10% on regular price

Amount of discounted item at store B = [tex]\frac{10}{100}\times78 = \$7.8[/tex]

Now regular price of item with discount at store B will be equal to Regular price of item at store B minus Amount of discounted item.

regular price of item with discount at store B = [tex]78-7.8 = \$70.2[/tex]

Sales tax = 5% on purchase price

Amount of sales tax = [tex]\frac{5}{100}\times 60 = \$3[/tex]

Total Cost of item at Store B is regular price of item with discount at store B plus Amount of Sales tax.

framing in equation form we get;

Total Cost of item at Store B = [tex]70.2+3 =\$73.2[/tex]

The result when total cost of the item at Store B is subtracted from the total cost of the item at Store A  = $73.2 - $75 = $1.80.

Hence the result is $1.80.

Answer: Compound interest is $36.61

Step-by-step explanation:

Initial amount deposited into the account is $500 This means that the principal,

P = 500

It was compounded annually. This means that it was compounded once in a year. So

n = 1

The rate at which the principal was compounded is 3.5%. So

r = 3.5/100 = 0.035

It was compounded for 2 years. So

t = 2

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. Therefore

A = 500 (1+0.035/1)^1×2

A = 500(1.035)^2 = $535.61

Compound interest = 535.6 - 500 = $35.61

Final answer:

Mathematics question on similar triangles; triangles are similar if they have congruent corresponding angles and proportional sides obtained through AA, SSS, or SAS criterion. A similarity statement describes the correspondence of the vertices.

Explanation:

The question provided falls within the subject of Mathematics, specifically within the study of geometry and the concept of similar triangles. To determine if two triangles are similar, we must check if they have the same shape, which implies that their corresponding angles are equal and their corresponding sides are in proportion. In other words, two triangles are similar if their corresponding angles are congruent and the lengths of their corresponding sides are proportional. This can be verified by angle-angle similarity (AA), side-side-side similarity (SSS), or side-angle-side similarity (SAS). The similarity statement provides the order of correspondence of vertices between similar triangles.

When evaluating if triangles BAO and B1A1O are similar, we must compare their corresponding angles and sides. If the given information indicates that at least two angles of one triangle are congruent to two angles of another triangle (AA criterion), or that the sides are proportional (SSS or SAS criterion), then the triangles are similar. For instance, if ∠BAO ≅ ∠B1A1O and ∠BOA ≅ ∠B1O1A1, then by the AA criterion, the triangles are similar, and we could write the similarity statement as triangle BAO ∼ triangle B1A1O.

Final answer:

To complete the statement describing the expression (a+b)(d+e)(a+b)(d+e), we expand it by multiplying each term. Simplifying the expression, we get a²*d² + 2a²de + 2abde + b²e².

Explanation:

To complete the statement describing the expression (a+b)(d+e)(a+b)(d+e), we need to expand it. This can be done by multiplying each term in the first factor by each term in the second factor and then multiplying the result by the third factor. So the expression becomes:

(a+b)(d+e)(a+b)(d+e) = (a*d + a*e + b*d + b*e)(a*d + a*e + b*d + b*e)

We can simplify this further by combining like terms:

(a*d + a*e + b*d + b*e)(a*d + a*e + b*d + b*e) = a²*d² + 2a²de + 2abde + b²e²

It appears to fly faster than its actual speed.

Step-by-step explanation:

In general, if talking about velocities, the direction of the movement should also be taken into account. For example, if two objects move in opposite directions, a person inside one object observes that the other one moving in the opposite goes faster than its actual speed (because the velocities are summed up). If they are moving in the same direction the opposite phenomenon is true (the velocities are subtracted).

Finally, in this example the planes move in opposite direction, therefore, a plane flying in the opposite direction will appear to fly  faster.

The equivalent annual cost of the machine, considering a 10% return, is approximately $309,535 per year.

First, accumulate the total cost over the lifespan of the machine which is $750,000 (initial cost) + ($12,000 * 3 years) = $786,000. The equivalent annual cost can be calculated using the formula for the present value of an annuity: PV = PMT [(1 - (1 + r)^-n ) / r], where 'PMT' is the payment per period, 'r' is the rate of return, and 'n' is the number of periods. Rearrange to calculate PMT: PMT = PV * r / (1 - (1 + r)^-n). Substituting in given values gives us, PMT = $786,000 * 0.1 / [1 - (1 + 0.1)^-3] = $309,535/year.

Final answer:

To find the value of alpha given that alpha and beta are conjugate complex numbers, and alpha/beta^2 is real, we can use the equation |alpha - beta| = 2√3. We can substitute alpha = a + bi and beta = a - bi, and solve for a and b to find the value of alpha.

Explanation:

Let α and β be conjugate complex numbers such that α/β² is a real number and |α - β| = 2√3. We need to find the value of α.

Since α and β are conjugate complex numbers, they have the form α = a + bi and β = a - bi, where a and b are real numbers. Substituting these values into the given equation, we get:

|α - β| = |(a + bi) - (a - bi)| = |2bi| = 2|b| = 2√3

From this, we can conclude that |b| = √3. Since |b| is the absolute value of b, it is always positive. Therefore, we have two options: b = √3 or b = -√3.

If b = √3, then α = a + √3i. We can substitute this into the equation α/β² to check whether it is a real number.

α/β² = (a + √3i)/(a - √3i)² = (a + √3i)/(a² - 2a√3i - 3) = [(a(a² - 3) + √3i(3a - a²)] / (a² - 2a√3i - 3)

This expression is not a real number, so b ≠ √3.

If b = -√3, then α = a - √3i. We can substitute this into the equation α/β² to check whether it is a real number.

α/β² = (a - √3i)/(a + √3i)² = (a - √3i)/(a² + 2a√3i + 3) = [(a(a² + 3) - √3i(3a + a²)] / (a² + 2a√3i + 3)

This expression simplifies to (a(a² + 3) - √3(3a + a²))/ (a² + 3) = a - √3(2a + 1)/ (a² + 3)

For this expression to be a real number, the imaginary term √3(2a + 1) must be equal to 0. So, we have √3(2a + 1) = 0.

Solving this equation, we get 2a + 1 = 0, which implies a = -0.5.

Therefore, the value of α is α = -0.5 - √3i.
