Answer:[tex]330^{\circ}[/tex]

Step-by-step explanation:

Given

Circumference of circle [tex]C=12\ units[/tex]

Arc length [tex]l=11\ units[/tex]

we know arc length is given by

[tex]l=\frac{\theta }{360^{\circ}}\times 2\pi r[/tex]

substituting value we get

[tex]11=\frac{\theta }{360}\times 12[/tex]

[tex]\frac{11}{12}=\frac{\theta }{360}[/tex]

[tex]\therefore \ \theta =330^{\circ}[/tex]

The central angle of the arc is approximately 330 degrees.

The question involves finding the central angle of an arc in degrees when the circumference of the circle is 12 and the arc length is 11. To solve this, it's essential to understand the relationship between the arc length, the central angle, and the circumference of the circle.

The formula we use is (Central Angle in degrees) / 360 = Arc Length / Circumference. Given that the circumference is 12 and the arc length is 11, we can substitute these values into the formula to find the central angle.

Thus, the calculation is as follows: (Central Angle in degrees) / 360 = 11 / 12.

By cross-multiplication, we find that the

Central Angle in degrees = (11 / 12) × 360.

This gives us a central angle of approximately 330 degrees.

Answer:250 N

Step-by-step explanation:

Given

mass of skater on left side [tex]m_l=70\ kg[/tex]

mass of skater on right side [tex]m_r=90\ kg[/tex]

If the skater on the left experience a force of [tex]250\ N[/tex]

If they push against each other then they must experience  an equal force according to newtons third law

Thus [tex]F_l=F_r[/tex]

Thus skater on right experience [tex]250\ N[/tex] force

Using Newton's third law, if the first skater pushes off with a force of 250 N, the second skater will experience an equal but opposite force of 250 N. This occurs irrespective of the skaters' masses.

The subject of this question is physics, specifically Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In this case, the action is the first skater pushing off the second skater, and the reaction is the force experienced by the second skater.

The amount of force experienced by the first skater is 250 N. Because of Newton's third law, this means the second skater is also experiencing a force of 250 N. The direction of the force, however, is in the opposite direction to the force experienced by the first skater.

The force experienced by an object is independent of its mass. Therefore, despite the second skater having a mass of 90.0 kg versus the first skater's 70.0 kg, the force experienced remains the same.

In conclusion, the second skater experiences a force of 250 N.

The dimensions of the rectangle are 9 inches (width) and 16 inches (length) as obtained from solving the quadratic equation derived from the facts provided.

To solve this problem, let's denote the width of the rectangle as x in inches. Since we know that the length of the rectangle is 7 inches longer than its width, we can write it as x + 7 inches. The area of a rectangle is calculated by multiplying its length by its width. Here, it's given as 144 square inches.

Setting up the equation for the area, we get x(x + 7) = 144.

Solving this quadratic equation, we find that x = 9. As a result, the width is 9 inches and the length, being 7 inches longer, is 16 inches. Therefore, the dimensions of the rectangle are 9 inches by 16 inches.

Answer:

Expression A and C are correct because 9x - 3x = 6x and 5x + x = 6x, then -4

After simplification, Expression A (6x - 4) and Expression C (6x - 4) are equivalent to each other, but Expression B (12x - 4) is not equivalent to the other two.

The student's teacher presented a problem to determine the equivalence of three algebraic expressions: Expression A (9x - 3x - 4), Expression B (12x - 4), and Expression C (5x + x - 4).

Brianna incorrectly states that all three expressions are equivalent simply because they all evaluate to -4 when x = 0. However, this is a misinterpretation, as equivalence between algebraic expressions means that they yield the same result for all values of x, not just a single value.

To correct this, we simplify each expression:

Expression A: 9x - 3x - 4 simplifies to 6x - 4.

Expression B: 12x - 4 remains the same.

Expression C: 5x + x - 4 simplifies to 6x - 4.

After simplification, we see that Expression A is equivalent to Expression C, both simplifying to 6x - 4. However, Expression B remains different, with the term 12x - 4.a

Answer:

A) 53

B) 53%

C) 37%

D) 63%

E) Yes.

Step-by-step explanation:

A) 53 people did not get headaches at all.

B) To solve for the percentage of participants that reported they did not get a migraine headache, you will need to divide out of the TOTAL number of people:

53/100= .53 --> Convert to percentage--> .53×100 = 53%.

C) To find this value, you will need to divide out of the amount of people that took MEDICINE and got a headache:

22/60≈0.367--> Convert to percentage --> 0.367×100≈37%

D) This percentage will be found out of who did NOT take the medicine:

25/40= 0.625 --> Convert to percentage --> 0.625×100≈63%

E) The medicine did help prevent migraine headaches because the percentage that got migraines with the medicine is lower than the percentage that got migraines WITHOUT the medicine.

Answer:

  6 bags

Step-by-step explanation:

1 yard is 3 feet, so the area of the cage is ...

  A = LW

  A = (9 ft)(3 ft) = 27 ft^2

At 5 square feet per bag, the number needed is ...

  (27 ft^2)/(5 ft^2/bag) = 5.4 bags

We assume that Amelia can only buy whole bags, so ...

Amelia will have to buy 6 bags to cover the floor of the cage.

An arc is a segment of a circle. An arc measure is the measure of an angle that the arc creates in the center of a circle, while an arc length is the span of the arc. This measure can be given in degrees or radians. We can easily convert between the two using the fact that pi radians = 180 degrees.

Answer:

D) 114

Step-by-step explanation:

got it right on edge

Out of all 252 twelfth graders, the number of students that rode in a car to school is 114.

The first step is to determine the total number of students that rode a bicycle to school

Students that rode a bicycle to school = 815 - (276 + 196 + 314) = 29

The second step is to determine how many twelfth graders rode a bicycle to school: 29 - (8 + 10) = 11

Number of twelfth graders that rode a car to school = 252 - (99 + 11 + 28) = 114

HOW TO DETERMINE SLOPE AND Y-INTERCEPT: Use the instructions below to answer this question.

EQUATION: y=[tex]\frac{-3}{4}[/tex]x-3

-------------------------------------------------

FINDING THE Y-INTERCEPT:

Do this simply by finding the number your graph starts at on the Y-Axis (vertical line)! In this case, it's at -3!

FINDING SLOPE:

Remember that slope is rise over run ([tex]\frac{rise}{run}[/tex])

RISE = How far the line goes up and down.

RUN = How far the line goes left or right.

HOW DO I FIND IT? All you have to do is count both rise and run from one point on the line to another! WARNING: The point must hit at a vertex, it cannot be counted if it is in the center of the box, or anywhere that does not touch the edge. I also suggest starting from the Y-Intercept and counting.

GOING LEFT OR DOWN: This is a positive number

GOING RIGHT OR UP: This is a negative number.

(You will see how this applies, below, yayyyy)

CALCULATING OUR NUMERATOR, AKA RISE:

Starting from the y, to get to the next point on the line, you can see we have to go down three. This means our numerator is -3!

CALCULATING OUR DENOMENATOR, AKA RUN:

Starting from where we just stopped, we must continue getting to the next point, and to do that, you can see we have to go to the right four! This means our denomenator is 4!

Multiply the numerators and the denominators.

Step-by-step explanation:

Problem: [tex]\dfrac{1}{x^2}- \dfrac{2}{y}\div y-2x^2[/tex]

Step 1: [tex]\dfrac{y}{x^2y}- \dfrac{2x^2}{x^2y}\div y-2x^2[/tex]

Step 2: [tex]\dfrac{y-2x^2}{x^2y} \div \dfrac{y-2x^2}{1}[/tex]

Step 3: [tex]\dfrac{y-2x^2}{x^2y} X \dfrac{1}{y-2x^2}[/tex]

The next step would be to multiply the numerators and the denominators.

Step 4: [tex]\dfrac{y-2x^2}{(x^2y)(y-2x^2)}[/tex]

Since [tex]y-2x^2[/tex] is common in the numerator and denominator, it divides itself, thus our result is:

[tex]\dfrac{1}{x^2y}[/tex]

To solve the inequality -3(-3x - 4) < 66, first distribute the -3, then isolate the variable term resulting in 9x < 54 and divide by 9 to find x < 6 as the solution set.

Solving the Inequality

To solve the inequality -3(-3x - 4) < 66, we first distribute the -3 across the terms within the parentheses, which gives us 9x + 12 < 66.

Next, we subtract 12 from both sides to isolate the term with the variable, resulting in 9x < 54. Finally, we divide both sides by 9 to solve for x, which yields x < 6.

Thus, the solution set to the inequality is all real numbers less than 6.
