Theo used 2250 milliliters of water to water the garden.

Theo filled a watering can with 3 liters of water to water the garden. After using some of the water, he has 750 milliliters left in the can.

The amount of water used by Theo can be calculated by subtracting the remaining water from the total amount of water filled in the watering can.

For this, we first need to equate the unit of water present in the can initially with the amount of water left in the can.

We know, 1 liter = 1000 milliliters

Therefore, 3 liters = 3000 milliliters

This means that he used a total of 3000 milliliters - 750 milliliters = 2250 milliliters of water to water the garden.

Although certain functions have discontinuities, it is feasible to redefine the function so that it becomes continuous at that point.

A continuous function in mathematics is a function without discontinuities, or any sudden changes in value. If we can guarantee arbitrarily small changes in the input of a function by limiting small enough changes, then the function is continuous.

We only need to change the function's value at this point to make f(x) continuous at x=0. To satisfy the concept of continuous functions and resolve the example issue, make the necessary adjustment to make the one-sided limits equal. We therefore set f(0)=4 f(0) = 4

For the probability values - P(A) = 0.5, P(B) = 0.6, and P(A∩B) = 0.4, the values are -

a) P(A∪B) = 0.7

b) P(A∩B') = 0.2

c) P(A'∪B') = 0.6

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The given probability values are -

P(A) = 0.5

P(B) = 0.6

P(A∩B) = 0.4

a) The formula for finding P(A∪B) is -

P(A∪B) = P(A) + P(B) - P(A∩B)

Substitute the values into the equation -

P(A∪B) = 0.5 + 0.6 - 0.4

P(A∪B) = 0.11 - 0.4

P(A∪B) = 0.7

b) To find P(A∩B') use the formula -

P(A∩B') = P(B) - P(A∩B)

Substitute the values into the equation -

P(A∩B') = 0.6 - 0.4

P(A∩B') = 0.2

c) To find P(A'∪B') first find P(A'), P(B') and P(A'∩B').

P(A') = 1 - P(A)

Substitute the value -

P(A') = 1 - 0.5

P(A') = 0.5

Now, find P(B') -

P(B') = 1 - P(B)

Substitute the value -

P(B') = 1 - 0.6

P(B') = 0.4

Now, find P(A'∩B')

P(A'∩B') = 1 - P(A∩B)

Substitute the value -

P(A'∩B') = 1 - 0.7

P(A'∩B') = 0.3

The formula for finding P(A'∪B') is -

P(A'∪B') = P(A') + P(B') - P(A'∩B')

Substitute the values into the equation -

P(A'∪B') = 0.5 + 0.4 - 0.3

P(A'∪B') = 0.9 - 0.3

P(A'∪B') = 0.6

Therefore, the values are P(A∪B) = 0.7, P(A∩B') = 0.2 and P(A'∪B') = 0.6.

Using the concept of ratio in the similar triangles, the length scale factor is 1:25

Similar triangles are triangles that have the same shape but may be scaled differently. Two triangles are considered similar if and only if their corresponding angles are congruent (equal in measure) and the ratio of their corresponding sides is the same. This property is known as the "AA Similarity Postulate" or "Angle-Angle Similarity".

In other words, similar triangles have the same shape and proportional sides. This means that if two triangles are similar, corresponding sides are in proportion and corresponding angles are equal in measure.

In the given figures, the two triangles have areas of 3m² and 75m²

The formula of area of a triangle is given as ;

A = 1/2 (b * h)

Assuming the side lengths are equal, we can apply heron's formula which is given as;

S = [a + b + c / 2]

A = √s(s - a)(s - b)(s - c)

But a = b = c

Using the two triangles to find the ratio between the ratios;

Q : R = 3 : 75 = 1 : 25

The length will be given as;

Area = 1/2 b * h

b = h

75 = 1/2 * a * a

a² = 75 * 2

a² = 150

a = √150

In the second triangle;

3 = 1/2(b²)

6 = b²

b = √6

The ratio between Q to R = √6 : √150 = 1 : 25

We will have 0.44 or 44% of original money after 8 quarters. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

Four fundamental mathematical operations can be used to represent any real number, and they are as follows:

1. The sum of the numbers is calculated using the addition operator ('+').

2. Subtraction with the "-" sign, which results in the difference between the numbers.

3. Multiply ('×') the result when it is the product of the numbers.

4. Division ('÷'), which yields the numbers' quotient.

We are given that we started the company with $5,000,000 and we lose 7% of that start up cash every quarter.

So,

Amount lost every quarter = $5,000,000 * 7% = $350,000

Now,

Amount lost in 8 quarters = $350,000 * 8 = $2,800,000

Therefore,

Money left = $5,000,000 - $2,800,000 = $2,200,000

Thus,

Percentage left of original money = $2,200,000/$5,000,000 * 100 = 44%

Hence, we will have 0.44 or 44% of original money after 8 quarters.

The minimum of y = f(x) occurs at (x,y) = (3,1). Hence y= f(x) >=1 for all other x in its domain of definition.

What is Quadratic equation ?

Quadratic equation can be defined as equation in which it is in the form of ax^2 + bx + c = 0

where c is a constant.

y = f(x) + 3 merely increases the value y by 3 for any x, or just raises its graph up 3. The x-value for its minimum remains at x=3 and y = f(3) + 3 = 1 + 3 = 4.  Hence, new minimum = (3,4)

y = f(x-2) just shifts or translates the graph of f to the right by 2.  So what occurred at x=3 (the minimum y) now occurs at x=5  without changing y = 1.  Hence, new minimum = (5,1).

y = f(1.5x) compresses the x-scale without changing y.  So what happened at x=3 before now happens at x'=2 on the new scale.

Therefore, the minimum point now becomes  (2,1).

After his football game malik drinks 1/2 Liter of water and the 1/3 liter of juice did malik drink more juice draw an estimate to partition explain your answer

After his football game, Malik drank 1/2 liter of water and 1/3 liter of juice. To compare the amounts, we can draw an estimate by partitioning the 1 liter unit into equal parts. For example, we can divide 1 liter into 6 parts, each representing 1/6 of a liter.

If 1/2 liter of water is represented by 3 parts, then 1/3 liter of juice is represented by 2 parts. We can see that Malik drank more water than juice. This is because the partition representing 1/2 liter of water is longer than the partition representing 1/3 liter of juice.

Therefore, the answer is that Malik drank more water than juice.

If the cyclist rode for 1 hour at the same average speed, she would have ridden 17.4 miles.

To find the average speed of a cyclist, you can divide the total distance covered by the total time taken. In this case, the cyclist rode for 3.5 hours and completed a distance of 60.9 miles, giving an average speed of 60.9 miles ÷ 3.5 hours = 17.4 miles per hour. This average speed is constant, meaning that the cyclist would have traveled the same distance in 1 hour as she did in 3.5 hours if she kept the same pace.

Therefore, if the cyclist rode for 1 hour at the same average speed, she would have ridden 17.4 miles. This calculation is important for cyclists and other athletes as it helps them to determine their speed and track their progress over time.

Answer:

Step-by-step explanation:

y = 34  ==> y doesn't equal 34 billion as y is already measured in billions

Since y=10.5x:

34 = 10.5x  ==> solve for x

x = 34 / 10.5   ==> divide both sides by 10.5

x = 3.2  ==> x is approximately 3.2 years

2004 + 3.2 = 2007.2

2007.2 rounded to the nearest year is 2007

Hence, businesses will spend more than $34 billion in the year 2007 and beyond.
