Write the ratio in the simplest form comparing the monetary value of 2 nickels to that os 1 quarter
The ratio of the simplest form of 2 nickels to 1 quarter is 2:5.
What is defined as the ratio?The ratio can be defined as a comparison of two amounts of the same unit to determine that much of one amount is present in the other. Ratios are divided into two types. The first is a part-to-part ratio, and the second is a part-to-whole ratio. The part-to-part ratio expresses the relationship between 2 separate entities or groups. This ratio is represented by the fraction a/b. To simplify a ratio even further, we use the same method we used to simplify a fraction. a:b = a/b.For the given question;
The two monetary values are given as;
2 nickles and 1 quarter.
We know that;
1 nickles = 0.2 quarter.
For 2 nickles multiply both side by 2.
2 nickles = 2×0.2 quarter.
2 nickles = 0.4 quarter.
Find the ratio;
2 nickels to that of 1 quarter
2 nickels/ 1 quarter
Put the value of 2 nickle.
2 nickels/ 1 quarter = 0.4 quarter/1 quarter
2 nickels/ 1 quarter = 2/5
2 nickels: 1 quarter = 2:5
Thus, the ratio of 2 nickels to that of 1 quarter is found as 2:5.

Given that ΔABC is similar to ΔDFE , the value of x = 5.83 (rounded off to hundredth place)
Comparing the given pair of similar triangles,
A ↔ D
B ↔ F
C ↔ E
Now since the ΔABC ~ ΔDFE, the ratio of their sides are equal.
=> [tex]\frac{FE}{BC} = \frac{DF}{CA}[/tex] (by property of similarity of triangles)
=> [tex]\frac{x}{15} = \frac{7}{18}[/tex] (substituting respective values)
=> x = 5.83 (simplifying the algebraic equation to hundredth place)
As per the property of similarity of triangles, the corresponding sides have fixed ratio. Thus the ratio of two sides of a triangle will be numerically equal to the ratio of two corresponding sides of its similar triangle. Moreover, the corresponding angles of two similar triangles are equal in measure.

Given the two rectangles below. Find the area of the shaded region.10, 2, 4, 2
Applying the formula for the area of a rectangle, the area of the shaded region is calculated as: 42 units².
What is a Rectangle?A rectangle has two pairs of opposite sides that are of equal length, one pair is the length, while the other is the width.
How to Find the Area of a Rectangle?The area of a rectangle = the product of its length and its width = (length)(width).
The area of the shaded region = area of the larger rectangle - area of the smaller rectangle
Dimensions of the larger rectangle:
Length of the larger rectangle = 10 + 2 = 12 units
Width of the larger rectangle = 9 + 2 = 11 units
Area of the larger rectangle = (12)(11) = 132 units²
Dimensions of the smaller rectangle:
Length of the smaller rectangle = 10 units
Width of the smaller rectangle = 9 units
Area of the smaller rectangle = (10)(9) = 90 units²
The area of the shaded region = 132 - 90

17. Is the operation of forming Cartesian products commutative? Explain why or why not.
Choose the correct answer below.
OA. The operation of forming Cartesian products is commutative because order does not matter in
the definition of a Cartesian product.
OB. The operation of forming Cartesian products is not commutative because part of the definition of
a Cartesian product is the order of the elements generated by the two sets.
OC.
The operation of forming Cartesian products is commutative because a Cartesian product is
multiplication and multiplication is commutative.
O D. The operation of forming Cartesian products is not commutative because multiplication is not
commutative.
The operation of forming Cartesian products is not commutative because part of the definition of a Cartesian product is the order of the elements generated by the two sets.
==========================================================
Explanation:
Let's go over an example. We'll have these two sets
A = {1,2}
B = {3,4}
The cartesian product is this set of ordered pairs
A x B= {(1,3), (1,4), (2,3), (2,4)}
Each (x,y) pair has x as a value from the first set mentioned (A), and y a value from the second set mentioned (B). It might help to make a 2 by 2 table.
If we swap the order of set A and B then we have
B x A = {(3,1), (4,1), (3,2), (4,2)}
We can see that A x B does not equal B x A in this case. Therefore, the cartesian product operation is not commutative. The order matters.
Side note: Two sets are equal when they are subsets of each other.

SOLUTION
The image below will help in answering the following questions
Now, from the graph, the parts above the horizontal line represents profit, while the part below the horizontal line represents loss.
(a) Maximum profits are earned when there are 4 clerks working.
From the graph, we can see that this statement is CORRECT. The maximum profit is at 400 thousand dollars and takes place at 4 on the horizontal axis, this 4 represents 4 clerks working
(b) The store earns profits when no clerks are working.
No clerks are working when we consider 0 on the horizontal plane. From the picture above, tracing 0, it shows us something below the horizontal line which represents loss. So, this statement is INCORRECT. When no clerks work, there is a loss not profit
(c) Maximum profits are earned when there are 7 clerks working.
Tracing 7 from the graph, it doesn't fall on the top part of the curve which indicates maximum profit. Hence, this statement is INCORRECT.
d) The store earns about $400,000 in profits on its best days.
From the image above, we can see that this is correct.
(e) The store loses money when 8 or more clerks are working.
When we traced 8 from the horizontal line, it fell to the part of the graph which indicated loss.
Hence this is CORRECTstatement .

We need to know about scientific notation to solve this problem. The number of seconds the playlist will play is 3.99 x 10^5.
Expressing a number in scientific notation means writing the number as a multiple of ten with ten raised to some power. We use scientific notation for numbers that are very small or very big. When writing numbers in scientific notation we always have one number other than zero before the decimal point. In this question we know that there are 1900 songs and each song has average time of 3.5 minutes, we need to convert the minutes into seconds and multiply the number of seconds of each song to 1900.
1 min=60 seconds
3.5 mins=3.5 x 60=210 seconds
210 x1900=399000 seconds

The lake is 12,250 feets deep.
The elevation is changing in the downward direction and at a rate of -11ft/s.
So it means that the downward velocity of the probe is 11ft/s.
The value of downward acceleration is 9.8?m/s² which is equal to acceleration due to gravity.
The total time taken to reach down is 50seconds.
We can use the equation of motion because the acceleration is constant,
Using,
S = ut + 1/2at²
Where,
S is the depth of the pool,
U is initial velocity,
U is zero because the probe is dropped.
