The left and right page numbers of an open book are two consecutive integers whose sum is 335 find these page numbers.

The cost of the croissant before the increase was $0.60 and the cost of the cup of coffee was $1.65.

Let's assume the original price of a croissant is C dollars, the original price of a cup of coffee is F dollars, and the original price of a fruit bowl is B dollars.

From the given information, we can set up the following equations:

C + F + B = 5.25 (equation 1) - Total cost of the three items before the increase is $5.25.

1.25C + 1.4F + B = 4.80 (equation 2) - Total cost of the three items after the increase is $4.80.

B = 3C (equation 3) - The cost of a fruit bowl is 3 times the cost of a croissant.

Now, let's solve the equations:

Substituting equation 3 into equation 1, we get:

C + F + 3C = 5.25

4C + F = 5.25 (equation 4)

Substituting equation 3 into equation 2, we get:

1.25C + 1.4F + 3C = 4.80

4.25C + 1.4F = 4.80 (equation 5)

We now have a system of two equations (equations 4 and 5) with two variables (C and F). Solving this system of equations will give us the values of C and F, which represent the original costs of the croissant and the cup of coffee, respectively.

By solving equations 4 and 5 simultaneously, we can find that C ≈ 0.60 and F ≈ 1.65.

Therefore, the cost of the croissant before the increase was approximately $0.60 and the cost of the cup of coffee was approximately $1.65.

The required answer is Jocelyn travels approximately 0.83 miles in 5 minutes.

Jocelyn's car tires are spinning at a rate of 120 revolutions per minute. If her car's tires are 28 inches in diameter, we can calculate the distance traveled in one revolution by finding the circumference of the tire:

Circumference = π x diameter
Circumference = 3.14 x 28 inches
Circumference ≈ 87.92 inches

So in one revolution, the car travels approximately 87.92 inches. To find out how many miles Jocelyn travels in 5 minutes, we need to multiply the number of revolutions in 5 minutes (which is 120 revolutions per minute x 5 minutes = 600 revolutions) by the distance traveled in one revolution (87.92 inches).

Distance traveled in 5 minutes = 600 revolutions x 87.92 inches/revolution

Distance traveled in 5 minutes = 52,752 inches

To convert inches to miles, we can use the conversion factor given: 1 mile = 63,360 inches.

Distance traveled in 5 minutes = 52,752 inches ÷ 63,360 inches/mile

Distance traveled in 5 minutes ≈ 0.83 miles

Therefore, Jocelyn travels approximately 0.83 miles in 5 minutes with her car tires spinning at a rate of 120 revolutions per minute. Rounded to the nearest hundredth, the answer is 0.83 miles.
To find out how many miles Jocelyn travels in 5 minutes, follow these steps:

1. Calculate the circumference of one tire: Circumference = Diameter × π.
Circumference = 28 inches × π ≈ 87.96 inches.

2. Determine the distance traveled in one revolution: One revolution covers the circumference of the tire, which is 87.96 inches.

3. Calculate the distance traveled in one minute: 120 revolutions per minute × 87.96 inches per revolution ≈ 10,555.2 inches per minute.

4. Determine the distance traveled in 5 minutes: 10,555.2 inches per minute × 5 minutes = 52,776 inches.

5. Convert the distance from inches to miles: 52,776 inches ÷ 63,360 inches per mile ≈ 0.83 miles.

So, Jocelyn travels approximately 0.83 miles in 5 minutes.

A ratio of 5:7 means out of 12 books, 5 are in one category and 7 are in another. (The “category” isn’t specified in this problem.)

So here we’re STARTING with 36 books; we want to find a ratio that is equal to 5:7 and adds up to 36. Well 36 = 3(12), and so if we multiply each number in the ratio by 3 as well, we might get what we want. Doing that gives us 15:21, which adds up to 36 and is equal to 5:7. Boom, that’s the answer.

P.S. Here’s a question you can think about: why do ratios stay the same when you multiply each number by the same amount? (For example, why is 3:1 the same as 6:2?)

None of the given vectors belong to the span{V1, V2}.

To determine which vector does not belong to the span of V1 and V2, we need to check if the vector can be written as a linear combination of V1 and V2. Let's analyze each vector:

Vector 1: [2, 0, -5]

Vector 2: [6, 4, -15]

Vector 3: [2, -5, 6]

Vector 4: [14, -10, -15]

We want to determine if any of these vectors can be written as a linear combination of V1 and V2.

Assuming V1 = [2, 0, -5] and V2 = [6, 4, -15], we can write the following system of equations:

a * V1 + b * V2 = [2, 0, -5]

Solving this system of equations, we obtain:

2a + 6b = 2      (Equation 1)

4b = 0           (Equation 2)

-5a - 15b = -5   (Equation 3)

From Equation 2, we can see that b = 0. Substituting this into Equation 1 and Equation 3, we have:

2a = 2           (Equation 1')

-5a = -5         (Equation 3')

From Equation 1', we get a = 1. From Equation 3', we also get a = 1.

Therefore, we have a unique solution for a and b, which means that every vector in the span of V1 and V2 can be written as a linear combination of V1 and V2.

Hence, none of the given vectors, Vector 1, Vector 2, Vector 3, and Vector 4, does not belong to the span{V1, V2}.

In summary, when the two new children (ages four and twelve) are added to the existing group, the mean age increases from 8 to 8, and the standard deviation changes from its original value to approximately 3.74.

To determine the effect of adding two children (ages four and twelve) to the existing group of five children (ages five, six, eight, nine, and twelve) on the mean and standard deviation of ages, we need to calculate the new values.

Let's calculate the mean first:

Calculate the sum of the ages of the initial five children:

5 + 6 + 8 + 9 + 12 = 40

Add the ages of the two new children:

40 + 4 + 12 = 56

Calculate the new mean by dividing the sum by the total number of children (5 initial + 2 new):

56 / 7 = 8

Therefore, the new mean age is 8.

Now let's calculate the standard deviation:

Calculate the squared difference between each age and the mean for the initial five children:

\((5 - 8)^2 + (6 - 8)^2 + (8 - 8)^2 + (9 - 8)^2 + (12 - 8)^2 = 54\)

Calculate the squared difference between each new age and the new mean:

\((4 - 8)^2 + (12 - 8)^2 = 80\)

Calculate the sum of the squared differences for the initial five children and the new children:

54 + 80 = 134

Divide the sum of squared differences by the total number of children (5 initial + 2 new) and take the square root:

√(134 / 7) ≈ 3.74

Therefore, the new standard deviation is approximately 3.74.

  a) A = 73°, C = 59°, a = 16.7

  b) A = 11°, C = 121°, a = 3.3

Step-by-step explanation:

The Law of Sines can be used to find angle C. Then the sum of angles in the triangle can be used to find angle A. The length of 'a' can be found either from the Law of Sines or the Law of Cosines at that point.

The given angle is opposite the shorter of the two given sides, so there are two possible solutions.

Acute triangle solution

The Law of Sines gives the relation ...

  sin(C)/c = sin(B)/b

  sin(C) = (c/b)sin(B)

  C = arcsin(c/b·sin(B)) = arcsin(15/13·sin(48°)) ≈ 59°

Then angle A is 132° -59° = 73°, and side 'a' is ...

  a = 13·sin(A)/sin(B) = 13·sin(73°)/sin(48°) ≈ 16.7

__

Obtuse triangle solution

The other value of arcsin(15/13·sin(48°)) is used:

  C ≈ 121°   ⇒   A = 11°

  a = 13·sin(11°)/sin(48°) ≈ 3.3

__

The two solutions are ...

  A = 73°, C = 59°, a = 16.7

  A = 11°, C = 121°, a = 3.3

We note that the drawing is of an acute triangle, so that solution may be the one that is preferred.

Step-by-step explanation:

The total cost of power generation for a specific load demand can be calculated by optimally allocating the load demand to each unit based on their power output limits. The allocation is done in a way that minimizes the overall cost while meeting the load demand.

In the given power system depicted in Figure 1, there are three units that are always running. Each unit has specific characteristics regarding their minimum power output (Pmin), maximum power output (Pmax), and incremental cost (Ci). Let's discuss the characteristics of each unit and calculate the total cost of power generation for a given load demand.

Unit 1:

Pmin = 200 MW

Pmax = 500 MW

Ci = $50/MWh

Unit 2:

Pmin = 150 MW

Pmax = 400 MW

Ci = $40/MWh

Unit 3:

Pmin = 100 MW

Pmax = 300 MW

Ci = $30/MWh

To calculate the total cost of power generation for a given load demand, we need to determine the optimal power output for each unit. We start by considering the units with the lowest incremental cost first.

Suppose the load demand is D MW. We allocate the load demand to the units as follows:

Step 1: Check if Unit 1 can meet the load demand within its power range. If yes, allocate the load demand to Unit 1 and calculate the cost:

Cost1 = Ci * P1, where P1 is the power output of Unit 1.

Step 2: If there is still remaining load demand, allocate it to Unit 2:

Cost2 = Ci * P2, where P2 is the power output of Unit 2.

Step 3: If there is still remaining load demand, allocate it to Unit 3:

Cost3 = Ci * P3, where P3 is the power output of Unit 3.

Finally, the total cost of power generation, Cost_total, is the sum of Cost1, Cost2, and Cost3:

Cost_total = Cost1 + Cost2 + Cost3

To find the optimal power output for each unit, we consider the load demand and compare it to the minimum and maximum power output limits for each unit. The power allocation is based on meeting the load demand while minimizing the overall cost of power generation.

In summary, given the characteristics of the three units in the power system (Pmin, Pmax, and Ci), the total cost of power generation for a specific load demand can be calculated by optimally allocating the load demand to each unit based on their power output limits. The allocation is done in a way that minimizes the overall cost while meeting the load demand.
