Step-by-step explanation:

If 15 carpenters can build 3 houses in 3 hours, it means that each house takes 1 hour to complete with their combined effort. Therefore, it would take 5 carpenters the same amount of time, 1 hour, to build 1 house.

Given that 15 carpenters can build 3 houses in 3 hours, we can determine their collective rate of work. Since 3 houses are built in 3 hours, it means each house takes 1 hour to complete with the combined effort of the 15 carpenters. Now, if we reduce the number of carpenters to 5 while keeping the rate of work constant, it stands to reason that 5 carpenters would take the same amount of time, 1 hour, to build 1 house. The number of carpenters is inversely proportional to the time taken to complete a task, assuming the rate of work remains constant. Therefore, by reducing the number of carpenters from 15 to 5, we can still maintain the same rate of work and complete 1 house in 1 hour.

The average acceleration of Train A over the interval 2 ≤ t ≤ 8 is -40 meters per minute squared.

Explanation:

The average acceleration of a body over a given time interval is defined as the change in velocity divided by the time interval. In this case, we are given the velocity function vA(t) for Train A, and we want to find its average acceleration over the interval 2 ≤ t ≤ 8.

To find the change in velocity over this interval, we can subtract the velocity at t=2 from the velocity at t=8:

Δv = vA(8) - vA(2) = (-120) - 100 = -220 meters per minute

To find the time interval, we can subtract 2 from 8:

Δt = 8 - 2 = 6 minutes

Now we can use the formula for average acceleration:

a = Δv/Δt = (-220)/6 = -40 meters per minute squared

Therefore, the average acceleration of Train A over the interval 2 ≤ t ≤ 8 is -40 meters per minute squared.

The estimated cost of the new 3000-ft2 heat exchange system for the plant retrofit can be calculated using the power-sizing exponent and the price index. Based on the given information, the rough estimate for the cost of the new heat exchanger system is approximately $108,984.

To estimate the cost of the new heat exchange system, we need to consider the price index and the power-sizing exponent. The price index provides a measure of the change in prices over time. In this case, the price index 7 years ago was 1360, and the current price index is 1478.

To calculate the cost estimate, we can use the following formula:

Cost estimate = (Cost of previous heat exchanger) × (Current price index / Previous price index) × (New size / Previous size) ^ power-sizing exponent

Using the given information, the cost of the previous heat exchanger was $75,000, the previous size was 1200 ft2, and the new size is 3000 ft2.

Plugging in these values into the formula, we get:

Cost estimate = ($75,000) × (1478 / 1360) × (3000 / 1200) ^ 0.55

Simplifying the calculation, we find:

Cost estimate ≈ $108,984

Therefore, a rough estimate for the cost of the new 3000-ft2 heat exchanger system for the plant retrofit is approximately $108,984. It's important to note that this is just an estimate and the actual cost may vary based on specific factors and market conditions.

The probability that the number of residents that recognize the brand is not 4 is 0.86 , the probability that at least 7 people will recognize the brand is 0.29 and the probability that at most 5 people will recognize the coffee shop is 0.39.

Given Recognition rate of brand in town of Coffleton is 57% and sample size is 10.

We have to use binomial distribution:

P(X=x)=\(C_{n,x} p^{x} (1-p)^{n-x}\)

\(C_{n,x} =C!/r!(C-r)!\)

A) The parameters are as under:

x is the number of successes.

n is the number of trials which is 10 in this question.

p is the probability.

In this problem :

The brand name of a certain chain of coffee shops has 57% recognition rate in the town of coffleton , hence p=0.53.

There is a sample of 10 residents, n=10.

Probability that the no. of people that recognize the brand name is not 4 is as  under:

P(X≠4)=1-P(X=4)

P(X=4)=\(C_{10,4}(0.53)^{4} (0.43)^{6}\)

=0.1395

P(X≠4)=1-0.1395

=0.8605

B) P(X>=7)=\(C_{10,7} (0.57)^{7} (0.43)^{3} +C_{10,8} (0.57)^{8} (0.43)^{2} +C_{10,9} (0.57)^{9} (0.43)^{1} +C_{10,10} (0.57)^{10} (0.43)^{0}\)

=0.18012+0.081+0.0258+0.0036

=0.29

C)P(X<=5)=\(C_{10,1} (0.57)^{1} (0.43)^{9} +C_{10,2} (0.57)^{2} (0.43)^{8} +C_{10,3} (0.57)^{3} (0.43)^{7} +C_{10,4} (0.57)^{4} (0.43)^{6} +C_{10,5} (0.57)^{5} (0.43)^{5}\)

=0.00285+0.0146205+0.0432+0.126+0.21168

=0.3983.

Hence the probability that the number of residents that recognize the brand is not 4 is 0.86 , the probability that at least 7 people will recognize the brand is 0.29 and the probability that at most 5 people will recognize the coffee shop is 0.39.

1) The length of the side DE by similar triangle theorem is; Option C: 20

3) If RY = b + 4 and SE =20, then the value of b is; 6

Similar triangles are defined as triangles that have the same shape, but their sizes may vary. Thus, we can say that equilateral triangles, squares of any side lengths are as well examples of similar objects. This means that, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

1) ΔABC ~ ΔDEF

We are given the similar triangles ABC and DEF.

We are also told that ΔABC ~ ΔDEF.

Now, If AB = 10, AC = 8 and DF = 16

Thus, by similar triangle theorem, we can apply it to the attached triangle to get;

AB/DE = AC/DF

DE = (AB * DF)/AC

DE = (10 * 16)/8

DE = 20

3) Now, by using the concept of similar triangles, since we are given that;

R is the midpoint of line SH.

Y is the midpoint of line EH

RY = b + 4

SE =20

(b + 4)/20 = 1/2

Cross multiply to get;

2(b + 4) = 20

2b + 8 = 20

2b = 20 - 8

b = 12/2

b = 6

The parking lot is actually 49 meters.

Answer:

Rise: 200.25

Descent 300.2

Minutes

Step-by-step explanation:

A)        We are using the Pythagorean theorem for the climb and descent. (a^2 + b^2 = c^2)

For climb a = 200, b = 10 c = ?

200^2 + 10^2 = c^2 = 40000 + 100 = c^2 = 40100 = c^2

c = about 200.25

For the descent: a = 300, b = 10

300²+10² = c²

90000 + 100 = c²

90100 = c²

c = about 300.2

B) If a plane is going 600 km/h and it goes about 10 km that means the plane is only going for 10/600 of an hour.

Answer:

Option: A is the correct answer A.

Begin with a line segment on the paper and fold the paper so that the segment's endpoints lie on top of each other.

Step-by-step explanation:

We know that a perpendicular line segment is formed with the help of paper folding in following steps: Draw a line segment on a paper. Fold the paper so that the endpoints of the line segment are on each other. The crease that is formed on the paper and pass through the line segment is the perpendicular line to the given line segment. The point on the line segment is the mid point of the line segment. Hence, option: A is the correct answer.

Option: B is the correct answer i.e. "Begin with a line segment on the paper and fold the paper so that the segment's endpoints lie on top of each other."

We can rewrite the linear equation as:

-5y = 4 - 3x

y =  (3/5)x - 4/5

Now let's apply the dilation:

y = (5/3)*[ (3/5)x - 4/5]

y = x - 4/3

To find a length of a right triangle, we can use Pythagorean theory:

            leg² + leg² = hypotenuse²

The linear cost function of the computer shop in this scenario will be C(x) = 649x + 1500.

From the information, the linear cost function is C(x) = 649x + 1500 and the linear revenue function will be R(x) = 899x.

The cost of selling 37 computers will be:

C(x) = 649x + 1500

C(x) = 649(37) + 1500

C = 25513

The revenue from selling 37 computers will be:

R(x) = 899x.

R = 899(37)

R = 33263
