Answer:
15%
Step-by-step explanation:
9/60 = 0.15
The percentage of the club members voted for Teresa of approximately 15% of the chess club members voted for Teresa.
To calculate the percentage of club members who voted for Teresa, we can use the following formula:
Percentage = (Number of votes for Teresa / Total number of club members) × 100
Given that Teresa received 9 votes and the chess club has 60 members, we can plug these values into the formula:
Percentage = (9 / 60) × 100
Now, let's calculate the percentage:
Percentage = (0.15) × 100
Percentage ≈ 15%

In the figure below, if C is the center of the circle and 30 < C < 60, then which of the following expresses all possible values of a?
Select one:
A. 50 < a < 70
B. 60 < a < 70
C. 60 < a < 75
D. 75 < a < 90
E. 100 < a < 115
Answer:
Option C.
Step-by-step explanation:
In the given figure C is the center of the circle.
Let A and B are two points on the circle, such that
[tex]\angle A=a^{\circ},\angle B=b^{\circ}[/tex]
Since CA and CB are radius of the circle, therefore ABC is an isosceles triangle.
[tex]\angle A=\angle B=a^{\circ}[/tex]
Using angle sum property,
[tex]\angle A+\angle B+\angle C=180^{\circ}[/tex]
[tex]a^{\circ}+a^{\circ}+\angle C=180^{\circ}[/tex]
[tex]2a^{\circ}=180^{\circ}-\angle C[/tex]
Divide both sides by 2.
[tex]a^{\circ}=\dfrac{180^{\circ}-\angle C}{2}[/tex]
It is given that
[tex]30<C<60[/tex]
[tex]\Rightarrow 180-30>180-C>180-60[/tex] (Subtract from 180)
[tex]\Rightarrow 150>180-C>120[/tex]
[tex]\Rightarrow \dfrac{150}{2}>\dfrac{180-C}{2}>\dfrac{120}{2}[/tex] (Divide by 2)
[tex]\Rightarrow 75>a>60[/tex]
[tex]\Rightarrow 60<a<75[/tex]
Hence, the correct option is C.

Tia had a garden that was 2 meters long. Her brother used 458 millimeters of the length at one end as a worm farm.
How long is the part of the garden Tia can use for plants now?
1,542 centimeters
154 centimeters
1.642 centimeters
2.542 centimeters
Answer:
1542 millimeters or 15.42.42 centimeters
Step-by-step explanation:
The initial length being 2m converted to millimeters will mean we multiply by 1000 since
1m=1000mm
Therefore, 2m will be 2*1000=2000 mm
Part used was 458mm hence to get the remaining part we get the difference as follows
2000 mm -458 mm=1542 mm
Therefore, the length that can be used now is 1542 mm or 15.42 cm

Jada sells ground paprika
Her weekly profit (in dollars) as a function of the amount of paprika she sold that week (in kilograms) is
graphed
What is Jada's profit if she sells 60 kilograms of paprika?
Answer:
If Jada sells 60 kilograms of paprika, her profit would be $200.
Step-by-step explanation:
Note: The missing graph is attached below.
From the graph,
Taking two points
(35, 0) (60, 200)[tex]\mathrm{Slope\:between\:two\:points}:\:\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(35,\:0\right),\:\left(x_2,\:y_2\right)=\left(60,\:200\right)[/tex]
[tex]m=\frac{200-0}{60-35}[/tex]
[tex]m=8[/tex]
The equation of line in slope-intercept form is
[tex]y=mx+b[/tex]
Putting (60, 200) and m = 8 in the slope-intercept form
[tex]200=\left(60\right)\left(8\right)+b[/tex]
[tex]\left(60\right)\left(8\right)+b=200[/tex]
[tex]480+b=200[/tex]
[tex]\mathrm{Subtract\:}480\mathrm{\:from\:both\:sides}[/tex]
[tex]480+b-480=200-480[/tex]
[tex]b=-280[/tex]
Thus
[tex]y=mx+b[/tex]
[tex]y=8x+\left(-280\right)[/tex]
[tex]y=8x-280[/tex]
Putting x = 60
[tex]y=8\left(60\right)-280[/tex]
[tex]y=200[/tex]
Therefore, if Jada sells 60 kilograms of paprika, her profit would be $200.

If three unbiased coins are tossed, then what is the probability of getting one or more heads is
The odds would be 7/8 that at least one would be a heads.
Step-by-step explanation:To find your answer, see each coin flip as unrelated to the last one.
For the first coin flip, you can either get heads or tails. So, there's only 2 possible outcomes.
Flip 1 (Outcome 1): H or T
Flip 1 (Outcome 2): H or T
But when it comes to the second flip, now each outcome has two possible "sub-outcomes" of their own. So there's now four total outcomes.
Flip 2 (Outcome 1) : H, H
Flip 2 (Outcome 2) : H, T
Flip 2 (Outcome 3) : T, H
Flip 2 (Outcome 4) : T, T
On the third flip, there would now be 8 outcomes. As each "sub-outcome" has own of their own.
Flip 3 (Outcome 1) : H, H, H
Flip 3 (Outcome 2) : H, H, T
Flip 3 (Outcome 3) : H, T, H
Flip 3 (Outcome 4 : H, T, T
Flip 3 (Outcome 5) : T, H, H
Flip 3 (Outcome 6) : T, H, T
Flip 3 (Outcome 7) : T, T, H
Flip 3 (Outcome 8): T, T, T
So all but one of the eight outcomes have at least one heads drawn. Due to this, the odds of an heads happening would be 7/8 within all of the possible outcomes.
8 books cost \$19.60$19.60dollar sign, 19, point, 60.
Which equation would help determine the cost of 101010 books?
Final answer:
The cost of 10 books can be found by dividing the total cost for 8 books ($19.60) by 8 to get the cost per book ($2.45), and then multiplying that by 10 to get the total cost ($24.50).
Explanation:
To determine the cost of 10 books if 8 books cost $19.60, we need to establish the price per book and then multiply that by 10. First, let's calculate the cost per book by dividing the total cost by the number of books:
Cost per book = Total cost ÷ Number of books = $19.60 ÷ 8 books = $2.45 per book
Now, using the cost per book, we can find the total cost for 10 books:
Total cost for 10 books = Cost per book × 10 = $2.45 × 10 = $24.50
Therefore, the equation that would help determine the cost of 10 books is:
Cost = $2.45 × Number of books
In this case, for 10 books, the cost would be:
Cost = $2.45 × 10

The function f(x)f(x) is a quartic function and the zeros of f(x)f(x) are -6−6, -5−5, -2−2 and 11. Assume the leading coefficient of f(x)f(x) is 11. Write the equation of the quartic polynomial in standard form.
[tex]\boxed{f(x) = 11x^4 + 22x^3 - 1001x^2 - 5632x - 7260}[/tex]
Explanation:A quartic function is a function given by the the following equation in standard form:
[tex]f(x)=a_{4}x^4+a_{3}x^3+a_{2}x^2+a_{1}x+a_{0} \\ \\ \\ Where: \\ \\ a_{4},a_{3},a_{2},a_{1},a_{0} \ \text{are constant} \\ \\ \text{and} \ a_{4} \ \text{is the leading coefficient}[/tex]
From the statement we must assume the leading coefficient of f(x) is 11, so:
[tex]a_{4}=11[/tex]
The zeros are:
[tex]x=-6 \\ \\ x=-5 \\ \\ x=-2 \\ \\ x=11[/tex]
So, we can write:
[tex]f(x)=11(x-(-6))(x-(-5))(x-(-2))(x-11) \\ \\ \\ So: \\ \\ \mathrm{Rule}:-\left(-a\right)=a \\ \\ \\ Then: \\ \\ f(x)=11\left(x+6\right)\left(x+5\right)\left(x+2\right)\left(x-11\right)[/tex]
[tex]Expand:\left(x+6\right)\left(x+5\right):\ x^2+11x+30: \ \text{Distributive Property} \\ \\ \\ Then: \\ \\ f(x)=11\left(x^2+11x+30\right)\left(x+2\right)\left(x-11\right) \\ \\ \\ Expand:\left(x^2+11x+30\right)\left(x+2\right):\ x^3+13x^2+52x+60: \ \text{Distributive Property} \\ \\ \\ Then: \\ \\ f(x)=11\left(x^3+13x^2+52x+60\right)\left(x-11\right)[/tex]
[tex]Expand: \left(x^3+13x^2+52x+60\right)\left(x-11\right):\ x^4+2x^3-91x^2-512x-660 \\ (Distributive \ property)[/tex]
Finally:
[tex]f(x) = 11(x^4 + 2x^3 - 91x^2 - 512x - 660) \\ \\ \boxed{f(x) = 11x^4 + 22x^3 - 1001x^2 - 5632x - 7260}[/tex]

Lara is putting lace trim around the border of a circular tablecloth. The tablecloth has a diameter of 1.2 meters. What is the length of the lace she needs? Round to the nearest tenth of a meter.
Answer:
3.8m
Step-by-step explanation:
Since Lara is putting lace trim around the border of a circular tablecloth, by the time she finishes she has covered the circumference.
The circumference of a circle is calculated using:
[tex]C=\pi \: d[/tex]
where d is the diameter of the circle.
It was given that the diameter of the circular table cloth is 1.2 meters.
[tex]C=3.14 \times 1.2[/tex]
[tex]C=3.768[/tex]
Therefore the length of the lace she needed is 3.8m
Final answer:
Lara will need 3.8 meters of lace trim for the border of her circular tablecloth, after rounding to the nearest tenth.
Explanation:
The student is asking about the circumference of a circle, which is the total length around the circle. Given the diameter of the tablecloth as 1.2 meters, the circumference can be found using the formula C = πd, where C is the circumference and d is the diameter. The value of π (pi) is approximately 3.14. So the length of lace Lara needs is C = 3.14 × 1.2 meters = 3.768 meters. After rounding to the nearest tenth of a meter, Lara would need 3.8 meters of lace trim.
solve -2 | 3x - 6 | + 5 = 1
Answer:
x = [tex]\frac{4}{3}[/tex], x = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Given
- 2 | 3x - 6 | + 5 = 1 ( subtract 5 from both sides )
- 2 | 3x - 6 | = - 4 ( divide both sides by - 2 )
| 3x - 6 | = 2
The absolute value function always returns a positive solution, however, the expression inside can be positive or negative, that is
3x - 6 = 2 ( add 6 to both sides )
3x = 8 ( divide both sides by 3 )
x = [tex]\frac{8}{3}[/tex]
OR
- (3x - 6) = 2, that is
- 3x + 6 = 2 ( subtract 6 from both sides )
- 3x = - 4 ( divide both sides by - 3 )
x = [tex]\frac{4}{3}[/tex]
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.
x = [tex]\frac{8}{3}[/tex] : - 2| 8 - 6 | + 5 = - 2| 2| + 5 = -2(2) + 5 = - 4 + 5 = 1 = right side
x = [tex]\frac{4}{3}[/tex] : - 2 | 4 - 6| + 5 = - 2| - 2| + 5 = - 2(2) + 5 = - 4 + 5 = 1 = right side
Thus the solutions are x = [tex]\frac{4}{3}[/tex] and x = [tex]\frac{8}{3}[/tex]
Answer:
x = 1⅓, 2⅔
Step-by-step explanation:
-2 | 3x - 6 | + 5 = 1

-2 | 3x - 6 | = -4
| 3x - 6 | = 2
3x - 6 = 2
3x = 8
x = 8/3 = 2⅔
3x - 6 = -2
3x = 4
x = 4/3 = 1⅓

A researcher measured the shoe size and math ability of a large group of children. She found that having a larger shoe size does not
indicate that a child has more or less math ability. What does her analysis show
There is no correlation between shoe size and math abity.
There is a correlation between shoe size and math ability. There may or may not be causation. Further studies would have to be done to determine
this.
There is a correlation between shoe size and math ability. There is probably also causation. This is because there is likely an increase in math
ability with an increase in shoe size
Answer:
There is no correlation between shoe size and math abity.
Step-by-step explanation:
The researcher's examination showed that there's no correlation between a child's shoe size and math ability. Hence, a larger shoe size doesn't inherently relate to better or worse math skills. The concepts of correlation and causation are critical in such evaluations.
Explanation:The researcher's analysis indicates that there is no correlation between a child's shoe size and their math abilities. In other words, having a larger shoe size does not necessarily mean that a child would be better or worse at mathematics. The subjects of correlation and causation are important in studies like these. Correlation refers to a mutual relationship or connection between two or more things. In this case, there is no evident correlation between shoe size and math ability. On the other hand, causation would mean that one event (a larger shoe size) is the result of the occurrence of the other event (higher math ability), which in this scenario is not the case.

What parts of the American System are still in effect today
Answer:
Many of the policy tools used by these earlier American systems are obsolete today. But the idea is not. Now, as in the nineteenth and twentieth centuries, national economic development rests on a mutually reinforcing triad of policies to encourage American industry, national infrastructure, and adequate finance.
The principles of economic nationalism, financial stability, and infrastructure development remain influential in modern economic policy.
The American System, also known as the National System or Henry Clay's American System, was an economic plan devised by American statesman Henry Clay in the early 19th century. The plan aimed to promote economic growth and national unity by focusing on three key areas:
Tariff Protection: Clay advocated for high tariffs on imported goods to protect American industries from foreign competition. This policy is still reflected in modern trade agreements, where tariffs are used to balance trade and protect domestic industries.
National Bank: Clay supported the establishment of a strong national bank to regulate the money supply, stabilize the economy, and facilitate commerce. While the specific form of the Second Bank of the United States, which Clay supported, is no longer in existence, the concept of a central bank remains central to modern economic policy.
Internal Improvements: Clay believed in investing in infrastructure projects such as roads, canals, and railroads to improve transportation and connect different regions of the country. This concept is still relevant today, as governments continue to invest in infrastructure to support economic growth and mobility.

The maximum diameter of a bowling ball is 8.6 inches. What is the volume to the nearest tenth of a bowling ball with this diameter?
Answer:
333 cubic inches
Step-by-step explanation:
Hello, I can help you with this.
according to the question the maximum diameter of a bowling ball is 8.6 inches.
[tex]D_{max}=8.6 inches\\[/tex]
Step one
using this equation find the radius of the ball
remember
Diameter=2*radius
diameter/2= radius
put the value into the equation
8.6 inches/2= radius
radius=4.3 inches
Step two
using the known radius , find the volume
the volume of a sphere is given by
[tex]V=\frac{4}{3}\pi *radius^{3}[/tex]
put the value of radius into the equation
[tex]V=\frac{4}{3}\pi *(4.3\ in) ^{3} \\\\V=\frac{4}{3}\pi *79.507\ in ^{3}\\V=333.03 in ^{3}[/tex]
so, the volume to the nearest tenth of a bowling ball with this diameter is 333 cubic inches.
I hope it helps, have a good day.
Answer:
The volume of the bowling ball to the nearest tenth is v ≈ 106.0π in³ in terms of π or v≈332.9 in³
Step-by-step explanation:
To find the volume of the bowling ball, we will follow the steps below;
First write down the formula for calculating the volume of a sphere
v=[tex]\frac{4}{3}[/tex]πr³
where v = volume of the ball and r = radius of the ball
From the equation given, the diameter of the ball is 8.6 inches but radius is half of diameter, this implies that r= d/2 = 8.6/2 = 4.3, that is; radius=4.3 inches.
Let substitutes the value into the equation
v=[tex]\frac{4}{3}[/tex]×π×(4.3)³
v = [tex]\frac{4}{3}[/tex]×π×79.507
v =106.009π
v ≈ 106.0π in³
we can take π=3.14
v = 106.009×3.14
v =332.86826
v≈332.9 in³
The volume of the bowling ball to the nearest tenth is v ≈ 106.0π in³ in terms of π or v≈332.9 in³
