1 answer

Let's go through each question one by one and provide the answers where possible.

Question 1

Using the values provided (y=24, z=5, p=10), we'll find segment x. The solution depends on how these segments are related, but without the visual or formula, I cannot provide an accurate calculation. Please clarify or provide details.

Question 2

Using the secant-tangent theorem: \[ \frac{SR}{ST} = \frac{TU}{SQ} \] Given:

  • \(SR = 12\)
  • \(SQ = 30\)
  • \(ST = 9\)
  • \(TU = 5x - 24\)

We can set it up as: \[ \frac{12}{9} = \frac{5x - 24}{30} \] Cross-multiplying gives: \[ 12 \cdot 30 = 9(5x - 24) \] \[ 360 = 45x - 216 \] Now, solving for \(x\): \[ 45x = 576 \] \[ x = \frac{576}{45} \] To simplify: \[ x = 12.8 \] This value isn't among the given options. Please check the input values.

Question 3

To find the length of AO: \[ BO + AO = BA \] So: \[ AO = BA - BO = 108 - 45 = 63 \] Therefore, \( AO = 63 \) in.

Question 4

The measure of arc JK corresponds to angle JMK: Arc \(JK = m \angle JMK\) should follow the relation: \[ \text{Arc} = 2 \times \text{Angle at circle} \] So, \[ 5x - 59 = 2(4x - 32) \]

Solving will give you \( x \) and subsequently help determine \( m\angle JLK \). Please provide further details if needed.

Question 5

If arc KJ = 13x - 10 and arc JI = 7x - 10, assume: \[ m \angle KIJ = \frac{Arc_{KJ} + Arc_{JI}}{2} \] You can sum and solve for \(x\), allowing you to calculate \(m <KIJ\).

Question 6

This question appears incomplete. Please provide relevant values or context.

Question 7

Given the angles:

  • m<B = 93 degrees
  • mBC = 58 degrees
  • mCD = 106 degrees

Using triangle sum properties: \[ m∠A + m∠B + m∠C + m∠D = 360° \]

Simplifying will provide each angle measure, but a more precise setup is needed.

Question 8

To calculate the distance around the circular path given the diameter (the length of the sidewalk) being half a mile: The circumference \(C = \pi \times d\) where \(d = 1\) mile (diameter). Thus, \[ C = \pi \times 1 \approx 3.14 \text{ miles} \] To one decimal point, \(C \approx 3.1\) miles.

Question 9

If the area \(A = 674 m^2\), then using: \[ A = \pi r^2 \] Solve for the diameter \(d = 2r\): \[ 674 = \pi r^2 \] \[ r^2 = \frac{674}{\pi} \] Calculating \(d\) will yield the nearest value.

Question 10

With a diameter of 10 feet, the circumference \(C = \pi \times d = 10\pi\). The measure of a central angle can be determined: \[ \Theta = \frac{arc \ length}{C} \times 360° \]

Question 11

To find the arc length, we use: \[ Arc \ Length = r \cdot \Theta \] Substituting the radius and angle.

Question 12

This question requires finding the ratios of circumferences which can be done easily.

Question 13

To find the area of the sector: \[ Area = \frac{\theta}{360} \times \pi r^2 \]

Question 14

For the cookie cake, calculate: \[ Area = \pi r^2\] And then determine the area related to the angle eaten.
