Final answer:

By adding the fractions of votes for the museum (5/12) and zoo (5/24), converting them to a common denominator, and subtracting from the whole, we find that 3/8 of the class voted for the nature park.

Explanation:

To determine what fraction of the class voted for the nature park, we first need to add up the fractions of the class that voted for the museum and the zoo, and then subtract that sum from the whole class, which is represented as 1 (or 12/12). Since 5/12 of the class voted for the museum and 5/24 of the class voted for the zoo, we need to find a common denominator to add these fractions together. The lowest common denominator for 12 and 24 is 24.

First, we convert 5/12 to a fraction with a denominator of 24, which would be 10/24 (since 5 × 2 = 10 and 12 × 2 = 24). Now we can add the two fractions:

10/24 (votes for the museum)

5/24 (votes for the zoo)

Therefore, 10/24 + 5/24 = 15/24. After that, we subtract the sum from the whole to find out what fraction voted for the nature park:

12/12 - 15/24 = 24/24 - 15/24 = 9/24.

Hence, 9/24 of the class voted for the nature park. However, we can simplify 9/24 by dividing the numerator and the denominator by their greatest common divisor, which is 3, giving us 3/8.

Therefore, 3/8 of the class voted for the nature park.

Answer: Yes ΔRWS≈ΔQWT.

Step-by-step explanation:

We know that when two chords intersect each other inside a circle, the products of their segments are equal.

Therefore, [tex]QW\times WS=TW\times RW\\\Rightarrow\frac{QW}{RW}=\frac{TW}{WS}[/tex]

Now in triangle QWT and triangle RWS

∠QWT=∠RWS     [Vertically opposite angles]

[tex]\frac{QW}{RW}=\frac{TW}{WS}[/tex]

Therefore, By SAS similarity rule

ΔRWS≈ΔQWT

Therefore, yes ΔRWS≈ΔQWT.

After a 270-degree counterclockwise rotation, the first car on the ferris wheel originally located at (0, 40) will be at (40, 0).

If the first car of a ferris wheel is located at the point (0, 40) on a coordinate plane and undergoes a rotation of 270 degrees counterclockwise about the origin, the new coordinates of the first car can be determined by applying a rotation transformation. To perform a 270-degree counterclockwise rotation, we rotate the point 90 degrees clockwise. This equivalent action simplifies the calculation, as rotating (0, 40) 90 degrees clockwise results in the point moving to (40, 0). Therefore, after a 270-degree counterclockwise rotation (which is equivalent to a 90-degree clockwise rotation), the new coordinates of the first car on the ferris wheel are (40, 0).

Final answer:

It will take 4 years for the balance of an account to grow from $5000 to $6500 at a 7.5% simple interest rate. The formula for simple interest I = P × r × t is used, and after rearranging to solve for t, we find t = 4 years.

Explanation:

To calculate how long it will take for the balance of an account to reach a certain amount with simple interest, we can use the formula for simple interest: I = P × r × t, where I is the interest earned, P is the principal amount (initial deposit), r is the annual interest rate, and t is the time in years. In this case, we want to find out when the account balance will be $6500 after depositing $5000. The total interest earned to reach $6500 will be $6500 - $5000 = $1500.

The given annual interest rate is 7.5% (or 0.075 when converted to decimal form). We will rearrange the simple interest formula to solve for t:

t = I / (P × r)

Now, substituting the given values:

t = $1500 / ($5000 × 0.075)
t = $1500 / $375
t = 4 years

Therefore, it will take 4 years for the balance of the account to be $6500 at a 7.5% simple interest rate.

The eccentricity of a completely flat ellipse ranges from one (1) to zero (0).

Eccentricity of an ellipse is the measure of how 'out of round' an ellipse is.  

The eccentricity of an ellipse ranges from 0 to 1.

If the eccentricity is 0, it is not squashed at all and it will remain a circle.

However, if the eccentricity is 1, it is completely squashed and looks like a straight line.

Thus, the eccentricity of a completely flat ellipse ranges from one (1) to zero (0).

Answer : The given polynomial equation can have 0,2 or 4 complex roots.

Explanation:-

Given polynomial equation is [tex]3x^5-2x+1=0[/tex] which is a polynomial of degree 5.

We know that the complex roots always occur in pair ,therefore the number of complex roots in any polynomial must be an even number but less than equal  to the degree of polynomial.

Thus, the given polynomial equation has 4 complex roots.

Answer:

The polynomial equation have 4 complex roots.

Step-by-step explanation:

We are given a polynomial equation as:

[tex]3x^5-2x+1=0[/tex]

clearly the polynomial equation is a equation of degree 5 hence, the polynomial equation has atmost 5 roots.

Now we find the roots of the equation by it's graph.

we could clearly see that the graph ofthe function passes through the point (-1,0). hence -1 is the root of the polynomial equation, other than this point the graph does not touches or pass through the x-axis.

Hence, the other four roots of the polynomial equation are complex.

Hence, the polynomial equation has 4 complex roots.

The number of ways the golfer can make his choices is 4 hats times 3 gloves times 2 shoes, resulting in 24 different combinations.

The student is asking about the number of different ways a golfer can choose from 4 hats, 3 gloves, and 2 pairs of shoes. To find the total number of combinations, we multiply the number of choices for each category. Thus, the number of ways the golfer can make his choices is:

4 (hats) × 3 (gloves) × 2 (shoes) = 24 combinations.

This is not an instance where factorial calculation (4!) is necessary, since the golfer does not need to select one of each item in a specific order but simply needs to choose one from each category.

To calculate the number of ways the golfer can make his choices, we can use the concept of permutations.

For the hats, there are 4 choices. For the gloves, there are 3 choices. And for the shoes, there are 2 choices.

To find the total number of combinations, we multiply the number of choices for each category together: 4 hats * 3 gloves * 2 pairs of shoes = 24 different ways the golfer can make his choices.

Final answer:

The golfer can choose his accessories in 24 different ways by selecting 1 out of 4 hats, 1 out of 3 gloves, and 1 out of 2 pairs of shoes, and multiplying the choices together (4 × 3 × 2).

Explanation:

The question asks us to calculate the total number of ways the golfer can choose his outfit accessories assuming he chooses one of each type. To do this, we need to consider each type of accessory independently and multiply the number of choices for each type.

The golfer has 4 different hats, 3 pairs of gloves, and 2 pairs of shoes to choose from. Since these choices are independent of each other, we simply multiply the number of options for each type of accessory:

Thus, the total number of combinations is 4 hats × 3 gloves × 2 shoes = 24 different ways the golfer can choose his accessories for the round of golf.

This is an example of a fundamental counting principle problem, where we multiply the number of choices in each step to get the total number of combinations.

Answer:

The length of A'B' is 4 unit.

Step-by-step explanation:

Translation is a rigid transformation in which a figure or a line segment is shifted or moved without changing its shape and size,

That is, if the measurement of segment AB is 4 unit then after translation by any factor its measurement will not change,

So, the measurement of segment A'B' would be 4 unit.

Verification :

Let the coordinates of A and B are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] respectively,

Also, the rule of translation 1 unit right is,

[tex](x,y)\rightarrow (x+1, y)[/tex]

By the distance formula,

The measure of segment AB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Thus, if A'B' is the transformed segment of segment AB,

Then, coordinates of A' and B' are [tex](x_1+1, y_1)[/tex] and [tex](x_2+1, y_2)[/tex]

So, the measure of segment A'B' = [tex]\sqrt{(x_2+1-x_1-1)^2+(y_2-y_1)^2}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Hence, the measure of AB = measure of A'B'

42 received an A
 so 40-42 = 38 did not

the fraction would be 38/80, divide both numbers by 2

38/80 reduces to 19/40 did not receive an A

Out of 80 students, 38 did not receive an A, resulting in the fraction who did not receive an A being 19/40 after simplifying.

In a class of 80 students, if 42 received a grade of A, then the number of students who did not receive an A is the total number of students minus the number who did receive an A. So, 80 students − 42 students = 38 students. The fraction of the class that did not receive an A is 38 out of 80, which can be simplified by dividing both the numerator and the denominator by their greatest common factor, which is 2.

Therefore, the reduced fraction is 19/40.

The fraction of the class that did not receive an A is 19/40 which, if we converted into a percentage, would be 47.5%.
