What is the length of DE
The length of DE is 6 inches.
I can see that from the image, DE is a horizontal line segment that is 6 units long. This is because the x-axis is labeled in units, and DE spans 6 units on the x-axis.
we know that
The triangle XYZ and DEF are similar triangles
therefore
The ratio of their corresponding sides is equal
12/8 = 9/x
x = 8 * 9/12
x = 6 Units.
Therefore the length of DE is 6 inches.

Bob wants to distribute his fish and plants without any left over. 5 tanks 18 plants 24 fish
The problem is that Bob cannot evenly distribute his 24 fish and 18 plants across 5 tanks due to left over quantities when the numbers are divided.
Explanation:The problem presented is a math problem requiring the use of division and balance. It involves Bob trying to evenly distribute his 24 fish and 18 plants across 5 tanks. An effective way is to divide the quantities of fish and plants by the number of tanks. Therefore, if there are 5 tanks, 24 fish would be divided by 5, giving 4 fish with 4 left over, and 18 plants divided by 5 gives 3 plants each with 3 left over. This indicates that an even distribution is not possible with these numbers, because there would always be a excess quantity of fish and plants beyond what can be put in the 5 tanks.

To distribute the fish and plants without any leftover, divide the total number of fish and plants by the number of tanks.
Explanation:To distribute the fish and plants without any leftover, Bob needs to divide them equally among the tanks. To find out how many fish and plants should be in each tank, we need to divide the total number of fish and plants by the number of tanks.
Number of fish in each tank = 24 fish / 5 tanks = 4 fish per tank.
Number of plants in each tank = 18 plants / 5 tanks = 3.6 plants per tank. Since we can't have a fraction of a plant, we can round it up to 4 plants per tank or distribute the leftover plant evenly among the tanks.

Amir drove from Jerusalem to the lowest place on earth, the Dead Sea.
The statement is true. Amir did indeed drive from Jerusalem to the Dead Sea, which holds the distinction of being the lowest point on Earth in terms of land elevation.
True. Amir drove from Jerusalem to the Dead Sea, which is indeed the lowest place on Earth in terms of land elevation. The Dead Sea is a remarkable geographical feature located in the Jordan Rift Valley and is renowned for its extreme salinity, making it one of the saltiest bodies of water on Earth. The surface of the Dead Sea lies approximately 430 meters (1,410 feet) below sea level, and its shores border both Jordan to the east and Israel and the West Bank to the west.
Jerusalem, on the other hand, is situated on a plateau in the Judaean Mountains, and the drive from Jerusalem to the Dead Sea involves descending from higher elevations down to the low-lying area where the Dead Sea is located. This journey provides travelers with a striking transition from the elevated terrain around Jerusalem to the uniquely low and buoyant waters of the Dead Sea.
The Dead Sea's remarkable location and its high salinity levels have made it a popular destination for tourists seeking the therapeutic benefits of its mineral-rich mud and the sensation of effortlessly floating on its surface. This natural wonder's status as the lowest place on Earth is well-documented and contributes to its global renown.

-x+3y=12 and y=6x+21 system of substitution
Answer:
(x, y) = (- 3, 3)
Step-by-step explanation:
given the 2 equations
- x + 3y = 12 → (1)
y = 6x + 21 → (2)
Substitute y = 6x + 21 into (1)
- x + 3(6x + 21) = 12 ← distribute
- x + 18x + 63 = 12
17x + 63 = 12 ( subtract 63 from both sides )
17x = - 51 ( divide both sides by 17 )
x = - 3
Substitute x = - 3 into (2) for y
y = (6 × - 3 ) + 21 = - 18 + 21 = 3
solution is (- 3, 3 )

A 15 ft ladder leans against the side of a house. The top of the ladder is 13 ft off the ground. Find x, the angle of elevation of the ladder. Round your answer to the nearest tenth of a degree.
Answer:
x= 60.1 degrees
Step-by-step explanation:
The triangle forms a right angle triangle
Opposite side of angle x = 13 ft
Hypotenuse of the triangle = 15
We know the opposite side and the hypotenuse
So we use trigonometric formula sin(x)
[tex]sin(x) = \frac{opposite}{hypotenuse}[/tex]
[tex]sin(x) = \frac{13}{15}[/tex]

A line has a slope of -5 and passes through the point (2, 2). An equation for this line is
A) y = 2x + 2
B) y = 2x - 5
C) y = -5x - 2
D) y = -5x + 12
Answer:
The equation of the line has a slope of -5 and passes through the point (2, 2) is y = -5x + 12 .
Option (D) is correct.
Step-by-step explanation
The equation of the line
y = mx + c
where m is the slope and c is the y - intercept .
As given
A line has a slope of -5 and passes through the point (2, 2).
The slope of the line is -5.
m = -5
Put in the equation of the line
y = -5x + c
Put x = 2 and y = 2
2 = -5 × 2 + c
2 = - 10 + c
2 + 10 = c
12 = c
Put the value of c in the y = -5x + c
y = -5x + 12
Therefore the equation of the line has a slope of -5 and passes through the point (2, 2) is y = -5x + 12 .
Option (D) is correct.
To find the equation of the line with slope -5 passing through (2, 2), use the point-slope form and simplify to get y = -5x + 12. Therefore, the correct answer is option D.
To find the equation of the line with a slope of -5 that passes through the point (2, 2), we can use the point-slope form of the equation of a line:
y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passes through.
Substituting the given values:
y - 2 = -5(x - 2)
Simplify this equation:
Distribute the -5: y - 2 = -5x + 10Add 2 to both sides to solve for y: y = -5x + 12Therefore, the equation of the line is y = -5x + 12, so the correct answer is option D.

Step-by-step explanation:
julie was looking at the architect's blueprint of her house.The scale drawing on the blueprint was 1/4 in = 1 ft.On the blueprint what are the dimensions of her bedroom if the actual dimension of her bedroom are 12 ft by 16ft
Using the scale factor 1/4 inch equals 1 foot to convert Julie's actual bedroom dimensions to the blueprint scale, the bedroom measures 3 inches by 4 inches on the blueprint.
Explanation:To find the dimensions of Julie's bedroom on the architect's blueprint when the scale drawing is 1/4 inch equals 1 foot, we first need to establish the unit scale as a ratio. Given that the actual dimensions of her bedroom are 12 feet by 16 feet, we convert these measurements to inches on the blueprint using the provided scale.
We use the ratios:
By cross-multiplying and dividing, we can find the blueprint measurements:
For length:
For the width:
Therefore, the dimensions of her bedroom on the blueprint are 3 inches by 4 inches.
To find the blueprint dimensions of Julie's bedroom using the scale 1/4 inch = 1 foot, the actual dimensions of 12 ft by 16 ft are converted to 48 inches by 64 inches respectively by multiplying each dimension by the inverse of the scale ratio (4 feet / 1 inch).
To find the dimensions of Julie's bedroom on the blueprint, we must use the scale given which is 1/4 inch = 1 foot. This means that for every foot in actual size, it is represented by 1/4 inch on the blueprint. To convert Julie's actual bedroom dimensions, 12 feet by 16 feet, to blueprint dimensions, we multiply each by the inverse of the given scale.
Calculation steps for the length:
Write the scale as a ratio: 1/4 inch / 1 foot.Calculate the inverse of this ratio for the conversion: (1 foot / 1/4 inch) = 4 feet / 1 inch.Then multiply the actual length (12 feet) by the inverse ratio: 12 feet * (4 feet / 1 inch).It gives us 48 inches when we multiply 12 by 4.For the width, follow the same steps:
The actual width is 16 feet.Multiply by the inverse ratio: 16 feet * (4 feet / 1 inch).It results in 64 inches when we multiply 16 by 4.Therefore, the dimensions of Julie's bedroom on the blueprint should be 48 inches by 64 inches.

In Iowa, the format for license plates is 2 numbers followed by 4 letters. However the letters I, O, W, A are not allowed and also the use of repeats is not allowed either. How many license plates are available?
Answer:
32291999
Step-by-step explanation:
Step 1
We will use the fundamental counting principle to work out the total number of possible plates. The fundamental principle of counting states that if a process can be completed in k steps, and that there are [tex]n_1[/tex] steps to complete the first step, [tex]n_2[/tex] steps to complete the second step and [tex]n_k[/tex] stepts to finish the kth step, then there are [tex]n_1\times n_2 \times ....\times n_k[/tex] ways to complete the steps.
Step 2
In this step we figure out the number of ways to complete each step given that no repetitions are allowed. Note that this will include the plate that has I,O,W,A.
The first step can be carried out in 10 ways because there are 10 digits.
The second step can be carried out in 9 ways because we are not allowed to repeat any digits.
The third step can be carried out in 26 ways as there are 26 letters of the alphabet.
The fourth step can be carried out in 25 ways because no repeats are allowed.
the fifth step can be carried out in 24 ways because two of the letters will already have been used.
The sixth step can be carried out in in 23 ways because three letters have been used already.
Step 3
The third step is to use the fundamental counting principle with the values listed in step 3. We will also subtract 1 from whatever value we get because we would have counted the combination with I,O,W,A in it. This calculation is shown below,
[tex]10\times 9\times 26\times 25\times 24\times 23-1=32291999[/tex]
To calculate the total number of available license plates in Iowa based on specific formats and restrictions.
License Plate Combination Calculation:
Since the format is 2 numbers followed by 4 letters, with restrictions on certain letters and repeat use, we calculate the possibilities step by step:
For numbers: 10 choices for each position, so 10×10 = 100 possibilities.
For letters: After considering the restrictions, we have 22 choices for the first letter, 21 for the second, 20 for the third, and 19 for the fourth, resulting in 22×21×20×19 = 155,760 possibilities.
Finally, multiplying the possibilities for numbers and letters gives us the total number of available license plates: 100 × 155,760 = 15,576,000.
