The value of x is 8 from the diagram given.
How do you calculate the sides of similar triangles?The corresponding sides of a similar triangle are said to be in proportion if and only if the corresponding angle are also equal.
To calculate the side of line x (|x|), we have to determine the ratios of the corresponding sides as:
[tex]\mathbf{\dfrac{BC}{DC} = \dfrac{AC}{EC}}[/tex]
[tex]\mathbf{\dfrac{x}{10} = \dfrac{12}{15}}[/tex]
x = 120/15
x = 8
Therefore, we can conclude that the value of x is 8.

The weather that is most likely to occur where Richard is is rain shower.
What type of weather is most likely to occur?
Weather is the state of the atmosphere of a particular place over a short period of time. There is low atmospheric pressure, so it is likely that it would rain. This is because when the atmospheric pressure is low, it is likely that it would rain.

Answer:
Rain shower is most likely to occur where Richard is. (Option c)
• The air pressure is lower than the normal and that's why it suggests that the rainfall will happen in that place because rainfall generally occurs in the place where the low pressure is formed.
• And,the temperature is above than the freezing point of the water so there are no chances of the snowfall in that place.
• That's why rainfall is the most probable thing that will happen in that place.

Trigonometry ruleThis rule is applied to triangles to determine the unknown sides and angles.
Given the following parameter
Opposite = 5m
Adjacent = x
angle = 23 degrees
According to the theorem of tangents
tan23 = opposite/adjacent
tan23 = 5/x
x = 5/tan23
x = 11.78m

The average speed, in km/minute, of the train is 2.79 km/minute
Calculating average speedFrom the question, we are to calculate the average speed in km/minute
From the given information,
Distance travelled = 503 km
Time taken = 3 hours = 3 × 60 minutes = 180 minutes
Using the average speed formula,
Average speed = Distance / Time
∴ Average speed of the train = 503 / 180
Average speed of the train = 2.79 km/minute
Hence, the average speed, in km/minute, of the train is 2.79 km/minute

Answers
Answer:
x(27 +24) or 3x(9 +8)0.5(n +5) or 2.5(n/5 +1)Step-by-step explanation:
The distributive property of multiplication over addition tells us that the product of a value and a sum will be the same as the sum of products of the value and the sum's addends. This property can be used to add or remove parentheses from an arithmetic expression.
a(b +c) = ab +ac . . . . expression of the distributive property
__
When applying the distributive property to a sum, the first step is to look for a factor common to the terms of the sum. That factor need not be the greatest common factor, though it is often useful if it is.
Below, we have written each expression using two different common factors.
a)27x +24x = x(27 +24) = 3x(9 +8)
__
b)0.5n +2.5 = 0.5(n +5) = 2.5(n/5 +1)
_____
Additional comment
Finding a common factor can make use of knowledge of multiplication tables, rules of exponents, and identities involving various functions used in algebraic expressions. It is sometimes useful to list the prime factors of each of the terms as an aid to finding a common one. Where fractions are involved, it is sometimes helpful to express them all using a common denominator.
The Euclidean Algorithm can also be useful for finding common factors.

Based on the transformations that occurred, the preimage is most likely the topmost right image.
Where is the preimage?The transformations list shows that the first transformation was the reflection across the horizontal line drawn.
When a reflection is done, the shape looks like the inverse of itself. The only shape that looks like an inverse and is therefore a reflection is the bottom right shape which means the preimage must be the top right image.

Option D ---> y=5x

When a line is directly proportional it means it crosses the origin so has a y- and x-intercept of 0.
So if we use the format y=mx+c, it will work but our c value will be 0 as I explained above .
To work out the gradient we simply take 2 points (0,0) and (1,5)) on the graph and use the gradient formula :
m = change in y ÷ change in x
m = 5÷1
m = 5
Therefore our direct proportion equation will be y=5x

The domain and range of the given function are equal to (0, 3.85) and (0, 18.75) respectively.
How to calculate the domain of the function?In this exercise, you're given the following function h(t) = -4.87t² + 18.75t. Next, we would equate the function to zero (0) to determine its domain as follows:
0= -4.87t² + 18.75t.
4.87t(-t + 3.85) = 0
t = 0 or t = 3.85.
Therefore, the domain is 0 ≤ t ≤ 3.85 or (0, 3.85).
How to calculate the range of the function?h(t) = -4.87t² + 18.75t
h(t) = -4.87(t² - 3.85t + 3.85 - 3.85)
h(t) = -4.87(t - 1.925)² + 18.05
Therefore, the range is 0 ≤ h ≤ 18.05 or (0, 18.75).
