Theo filled up a 3-liter watering can to water the garden. He has 750 milliliters of water left in the can. How much milliliters of water did theo use?
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.

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

1- If P(A) = 0.5, P(B) = 0.6, and P(ANB) = 0.4, find (a) P(AUB), (b) P(AB'), and (c) P(A'U B').
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.

The equation y=10.5x estimates the amount that businesses will spend, in billions of dollars, on a certain business technology, where x is the number of years after 2004. For what years will the spending be more than $34 billion?
Answer:
2007 and beyond.
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.
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
Answer:
Step-by-step explanation:
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.
In the diagram below, D E ‾ DE is parallel to A B ‾ AB . If D E DE is 5 5 less than D C DC, A C = 56 AC=56, and A B = 48 AB=48, find the length of D C ‾ DC . Figures are not necessarily drawn to scale. State your answer in simplest radical form, if necessary.
The length of line segment Dc is equal to 35 units.
How to determine the length of DC?In Mathematics, two geometric figures are considered to be congruent only when their corresponding side lengths are congruent and the magnitude of their angles are congruent.
Since side length DE is parallel to AB and side DE is 5 less than side length DC, we have the following:
DE = DC - 5
In Geometry, the corresponding side lengths of two similar geometric figures are proportionate and as such, we have the following:
DC/AC = DE/AB
DC/56 = DC - 5/48
48DC = 56(DC - 5)
48DC = 56DC - 280
56DC - 48DC = 280
8DC = 280

Find two numbers whose difference is 303, hcf is 101 and are 4 digits long.
Start by writing down two 4-digit numbers that have a difference of 303. The two numbers should be close together, but not the same number. For example, you could choose 9801 and 9498.
Next, find the factors of each number. For 9801, the factors are 3 x 3 x 11 x 101 and for 9498 the factors are 2 x 7 x 13 x 101.
Now, find the Highest Common Factor (HCF) of the two numbers. To do this, you can look at the factors of both numbers and find which ones are the same. In this case, the HCF is 101.
Finally, check if the difference between the two numbers is still 303. As 9801-9498 = 303, this is correct. Therefore, 9801 and 9498 are the smallest pair of 4-digit numbers with a difference of 303 and an HCF of 101.

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).

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%

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.

Maxwell is taking a trip to an island that is 275
miles away. He'll drive the first part of the trip,
then board a boat that will take him to the island.
Maxwell drives an average speed of 60 miles per
hour. The boat travels at a speed of 40 miles per
hour. If the whole trip takes him 5 hours, how
many miles long is the boat trip?
Answer:Let's call the distance of the boat trip "d".
Since the whole trip took 5 hours, and Maxwell was driving for part of it, we know that:
d/40 + x/60 = 5
where x is the number of hours Maxwell spent driving.
We also know that the distance he drove is equal to the total distance minus the boat trip:
275 - d = x * 60
So we can substitute this into the first equation:
d/40 + (275 - d)/60 = 5
Expanding and simplifying this equation gives us:
6d = 1800
Finally, dividing both sides by 6 gives us:
d = 300
So the boat trip was 300 miles long.

Miles receives $6,000 from his parents. He wants to buy an used car that costs $12,500. If
he invests the money from his parents into an account that pays 7.5% interest compounded
continuously, how long will it take before he has a enough money to buy the car? Round your
answer to the nearest year.
Answer:
10 years
Step-by-step explanation:
principal = 6000
int = 7.5% annual compounding CONTINUOUSLY = everyday
so every day of the year he gets 7.5% / 365
so annual effective rate =7.7876%
so to get to 12500 it'll take t years
12500 = 6000* (1+ 7.7876% )^t
2.0833=1.077876^t
solve for t
approximately 10 years
