Answer: The answer is (C) 10 to 25 centimetres.
Step-by-step explanation: We are to select the correct range by which the sea level has risen about over the last 100 years.
Scientists estimates that because of warming of the ocean and increased melting of land-based ice such as glaciers and ice sheets, the level of sea has risen from 10 to 25 centimetres over the last 100 years.
Thus, (C) is the correct option.

Numbers can be written in exponential form with a base of 10. For example, 100 is written as 10^2, 100,000 as 10^5, and 10,000 as 10^4.
Explanation:To write numbers in exponential form, you need to understand the concept of exponential notation which is a way to express a number as a base raised to a power. In each of the given cases, the base is 10.
For 100, there are two zeros following the 1. This means that 100 can be written as 10 to the power of 2, or 10^2.
Similarly, for 100,000, there are five zeros following the 1. This would be written as 10 to the power 5, or 10^5.
Lastly, 10,000, has four zeros following the 1. This would be written as 10 to the power of 4, or 10^4.

The larger of two numbers is one more than four times the smaller number. if the sum of the numbers is 106, find the numbers.
To solve the problem, create two equations based on the information given, then solve these equations step-by-step. After calculation, the two numbers are 21 and 85.
Explanation:Given the problem, we can translate and create two equations which are:
The larger number is one more than four times the smaller number. We can express this as: L = 4S + 1 The sum of the numbers is 106. We can express this as: L + S = 106
Step 1: From the first equation, we know that L = 4S + 1. We can substitute this into the second equation in place of L, giving us 4S + 1 + S = 106.
Step 2: Add up, and we get 5S + 1 = 106. Subtract 1 from both sides and we get 5S = 105.
Step 3: Divide both sides by 5 to solve for S, we get S = 21.
Step 4: Substitute S = 21 into the equation L = 4S + 1, you can calculate and find L = 85.
Therefore, the two numbers are 21 and 85.

B) 21,730 > 22,341
C) 22,341 > 21,730
D) 22,341 < 24,687
The false statement among the given options is B) 21,730 > 22,341. The greater than, less than symbols should be accurately used to compare two numbers. The other given statements are true.
Explanation:The false statement in the given options is B) 21,730 > 22,341. This statement is saying that 21,730 is greater than 22,341, which is false. In mathematics, '<' symbol represents 'less than' and '>' represents 'greater than'. So, the statement B) is false because 21,730 is not greater than 22,341, but less.
Comparing the following two statements A) 21,730 < 22,341 and C) 22,341 > 21,730, we can see they are actually the same statement, restated in a different manner. Both statements are saying that 21,730 is less than 22,341 which is true.
The statement D) 22,341 < 24,687 is also true because 22,341 is less than 24,687.

In the triangles below, ma + md = 90°. using the information given about the triangles below, determine how the triangles can be shown to be similar.
Answer:
The triangles are similar by AA
Step-by-step explanation:
The hypotenuse of a right triangle measures 10 inches and the side opposite to <0 one of the non right angles is 5 inches long
The measure of <0 is
30
45
60
90
?
The measure of angle <0 in the right triangle is approximately 30 degrees.
Explanation:To find the measure of angle <0 in the right triangle, we can use trigonometry. The side opposite to angle <0 is given as 5 inches. The hypotenuse is given as 10 inches. We can use the sine ratio to find the angle:
sin(<0) = opposite/hypotenuse
substituting the given values:
sin(<0) = 5/10 = 0.5
Now, to find the measure of angle <0, we can use the inverse sine function:
<0 = arcsin(0.5)
Using a calculator, we find that the measure of angle <0 is approximately 30 degrees.

At a toy factory, it takes 498.456 seconds to attach the wheels and hoods on 42 toy cars.
We have been given that toy cars are manufactured on an assembly line in a toy factory. Attaching the wheels takes 8.216 seconds. Attaching the hood takes 3.652 seconds.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 12×2 = 24
To determine the time it takes to attach the wheels and hoods on 42 toy cars
According to the given condition, the arithmetic form would be as
⇒ 42 × (8.216 + 3.652)
Calculate the sum of the difference to get,
⇒ 42 × (11.868)
Apply the multiplication operation, and we get
⇒ 498.456
Therefore, it takes 498.456 seconds to attach the wheels and hoods on 42 toy cars.

if a 40-foot tree casts a 12-foot shadow, find the length of the shadow cast by a 28-foot tree
12/40 =0.3
28 *0.3 = 8.4
it will cast a 8.4 foot long shadow
Answer:
The shadow cast by a 28-foot tree is 8.4 foot.
Step-by-step explanation:
The rule of three is a way of solving problems of proportionality between three known values and one unknown, establishing a relationship of proportionality between all of them. In the case of direct proportionality, when one magnitude increases, the other increases ( or if one magnitude decreases, the other will also decrease)
This is an example of application of this rule:
40 foot tree ⇒ 12 foot shadow
28 foot tree ⇒ x foot shadow
Then, to solve and calculate the value of x, which is the value of the shadow cast by the 28-foot tree, perform the count:
x=[tex]\frac{28*12}{40}[/tex]
x=[tex]\frac{336}{40}[/tex]
x=8.4
This means that the shadow cast by a 28-foot tree is 8.4 foot.

which pairs of angles are not always congruent when two parallel lines are cut by a transversal?
A. Vertical lines
B. Alternate exterior angles
C.corresponding angles
D. Consecutive interior angles
When two parallel lines are cut by a transversal vertical lines are not always congruent.
What are transversal?A line that goes through two lines in the same plane at two different points is called a transversal. When determining whether two or more other lines in the Euclidean plane are parallel, transversals play a role. Different kinds of pairs of angles are created when two lines intersect a transversal: alternate angles, corresponding angles, consecutive exterior angles, and consecutive interior angles. If the two lines are parallel, Euclid's parallel postulate states that consecutive interior angles are supplementary, that corresponding angles are equal, and that alternate angles are equal.
Given to find the pairs of angles are not always congruent when two parallel lines are cut by a transversal,
when parallel lines are cut by a transversal some pair of angles are congruent like alternative exterior angle, corresponding angles and
Consecutive interior angles all the pairs are congruent and equal.
but When a transversal line cuts through two parallel lines, vertical lines are not always congruent.

To have an inverse function, a function must be bijective, meaning it is both one-to-one (injective) and onto (surjective). An example is shown with the function f(x) = x^2 which is not injective, hence doesn't have an inverse function.
Explanation:In mathematics, to have an inverse function, the original function, represented as f, must be both injective (one-to-one) and surjective (onto). This dual property is called being bijective. This means every element of the function's domain maps to one distinct element in the function's range (injective) and that every element in the range has a pre-image in the domain (surjective).
For example, consider the function f(x) = x^2. This function is not injective, as both f(-2) and f(2) give the same output, hence it does not have a true inverse function across all real numbers.
