Answer:

0.825 inches per hour

Step-by-step explanation:

Invasive weed species can grow quickly. One variety grows up to 1.65 ft per day. How fast in inches per minute can this weed grow?

FACTS:

the weed grows up to 1.65 feet per day

there are 12 inches in 1 foot

there are 24 hours in 1 day

First, lets figure how many inches the weed can grow in one day:

= daily growth in feet per day * inches in 1 foot

= 1.65 feet * 12 inches

= 19.8 inches a day

If the weed can grown 19.8 inches a day, and there are 24 hours in a day:

= growth in inches per day/24 hours in 1 day

=19.8/24

= 0.825 inches per hour

The placement results provided, the student should start with Math 100.

The placement results indicate that the student has placements for Math 111, Math 100, and Math 102+. Math 111 typically corresponds to a higher-level course than Math 100, and Math 102+ implies a placement beyond Math 102.

To progress towards Math 103E, it is essential to follow the recommended course sequence. Usually, Math courses are designed to build upon previously learned concepts and skills. Starting with Math 100 would provide the foundational knowledge necessary to succeed in subsequent courses.

Therefore, the student should first start with Math 100, and upon successful completion, they can proceed to Math 103E. It is important for the student to consult with their academic advisor or the mathematics department at their institution for specific course placement and sequencing information to ensure they are following the appropriate path.

dy/dx = (y-3)(y+3) is the autonomous differential equation that satisfies all of the given properties.

The autonomous differential equation that satisfies all of the given properties is dy/dx = (y-3)(y+3). This equation has two equilibrium solutions at y = 0 and y = 3, and is positive for -inf < y < 0, and negative for 0 < y < 3, and positive for 3 < y < inf.

To demonstrate this, let's consider the equation at y=-3. Since y=-3 is less than 0, the equation can be simplified to dy/dx = 6. Since 6 is positive, y' is also positive, meaning that y is increasing. Similarly, if y=3, dy/dx = 0 which is neither positive nor negative, so y remains constant. Finally, for y>3, dy/dx = -6, which is negative, so y is decreasing.

Therefore, dy/dx = (y-3)(y+3) is the autonomous differential equation that satisfies all of the given properties.

Division is one of the four fundamental arithmetic operations. The amount of money the school needs to spend on computers is $95,522.32.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

The number of students in a class is 24, while the number of classes is 17. Therefore, the number of students in the classes should be,

\(\text{Total number of students} = 24 \times 17 = 408\)

Now, since, there should be a computer for every 3 students, therefore, the number of computers that will be needed are,

\(\text{Number of computer} = \dfrac{\text{Number of students}}{3} = \dfrac{408}{3} = 136\)

The cost of a single computer is $702.37, therefore, the cost of 136 computers will be,

\(\rm Total\ cost= (\text{Cost of a single computer}) \times 136\\\\ Total\ cost= (\$702.37) \times 136\\\\ Total\ cost= \$95,522.32\)

The point group of a substituted cyclobutene can be determined by examining its symmetry elements.

In group theory, point groups are used to describe the symmetry of a molecule. The point group of a molecule can be determined by examining its symmetry elements, such as rotation axes, reflection planes, and inversion centers.

In the case of substituted cyclobutene, we can assume that the four-membered ring is flat and that replacing hydrogen atoms with other substituents, such as X or Y, does not affect any other structural parameters.

Now, let's consider the point groups for two substituted cyclobutene: 1,1-dimethylcyclobutane and 1,2-dimethylcyclobutane.

1,1-dimethylcyclobutane has two methyl groups attached to the same carbon atom. The symmetry elements of this molecule include a C2 axis that passes through the two methyl groups and perpendicular to the plane of the ring. There are also two perpendicular mirror planes that bisect the ring and pass through the carbon atom with the two methyl groups.

Using the point group flowchart, we can determine that the point group for 1,1-dimethylcyclobutane is C2v.

On the other hand, 1,2-dimethylcyclobutane has two methyl groups attached to adjacent carbon atoms. This molecule has a C2 axis that passes through the two methyl groups and the ring, as well as two perpendicular mirror planes that bisect the ring and pass through the carbon atoms with the methyl groups.

Using the point group flowchart, we can determine that the point group for 1,2-dimethylcyclobutane is Cs.

The total cost to run Val’s AC costs for a summer month of 30 days will be $67.5.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Quantity of electricity used in kilowatts is;

1000 watts = 1 kilowatts

2,500 watts = 2.5 kilowatts

Given that Number of hours Val runs AC per day = 5 hours

Number of days = 30 days

Cost of electricity = $0.18 kilowatts per hour

The Cost of Val’s AC to run for a summer month of 30 days can be calculated as;

= Quantity of electricity used × Number of hours Val runs AC per day × Number of days × Cost of electricity

= 2.5 × 5 × 30 × 0.18

Hence 262 adults and 88chidren are in the audience

Step-by-step explanation:

Let the number adults be x

Let the number of children be y

If there are 350seats in the theatre then;

x+y =350 .... 1

Also if $10.50was charged for adults and $7.50 for children with total amount of $3411, then;

10.50x + 7.50 y = 3411..... 2

Solve simultaneously

From 1, x = 350-y

Substitute into 2:

10.50(350-y) +7.50y = 3411

3675-10.5y+7.50y = 3412

3675-3y = 3411

-3y = 3411-3675

-3y = -264

y = 264/3

y = 88

From 3: x = 350-y

x = 350-88

x = 262

To answer this question, we need to compare the ratios of miles traveled to gallons of gas used for car A and car B when they both use 1 gallon of gas.

For car A, we can see from the graph that 50 miles are traveled for every 2 gallons of gas used, or in other words, 25 miles are traveled for every 1 gallon of gas used. Therefore, car A can travel 25 times the distance for 1 gallon of gas.

For car B, we can see from the table that 40 miles are traveled for every 2 gallons of gas used, or in other words, 20 miles are traveled for every 1 gallon of gas used. Therefore, car B can travel 20 times the distance for 1 gallon of gas.

To compare the two ratios, we can divide the ratio of miles traveled to gallons of gas used for car A by the ratio for car B:

25/20 = 1.25

Therefore, car A can travel 1.25 times the distance car B can travel when both cars use 1 gallon of gas.

A truth table is a table that displays all possible combinations of truth values for the propositional variables in a logical expression and the resulting truth value of the expression.

It is an important tool in logic as it enables us to determine the validity of arguments, identify tautologies and contradictions, and simplify complex expressions. Truth tables provide a systematic and rigorous method of evaluating logical expressions and reasoning about their truth values.

With respect to the table, since there is at least one row where all premises are true but the conclusion is false (the fifth row in this case), the argument is invalid

Step-by-step explanation:

The 68-95-99.7 rule states that:

• 68% of the data is expected to be within one standard deviation from the mean.

• 95% of the data is expected to be within two standard deviations from the mean.

• 99.7% of the data is expected to be within three standard deviations from the mean.

Then, when the mean is $19,000 and the standard deviation is $500, we can estimate how many standard deviations we are from the mean for the values $17500 and $19000 calculating the z-score:

Then, we have three standard deviations to the left and no standard deviation from the mean for the right boundary.

We can picture this in the normal distribution curve as:

This is half the amount of data that if we have 3 standard deviations to each side of the mean, so we can expect to have 99.7% / 2 = 49.85% of the data within these limits.
