I should have payed more attention but can someone please guide me through this and build me up an answer.
Klio2033 [76]

Answer:

arc QM = 38°

Step-by-step explanation:

the inscribed angle NQM is half the measure of its intercepted arc NM , so

arc NM = 2 × 90° = 180°

the sum of the arcs in a circle = 360° , then

QN + NM + MQ = 360° , that is

142° + 180° + QM = 360°

322° + QM = 360° ( subtract 322° from both sides )

QM = 38°

Given a feedlot of about 2500 cows, if an individual cow produces about 40 liters of manure per day, how many kiloliters of manu
Grace [21]

9514 1404 393

Answer:

  3000 kL

Step-by-step explanation:

  (2500 cows)(40 L/day/cow)(30 day/mo)(1 kL/(1000 L)) = 2.5×40×30 kL/mo

  = 3000 kL/mo

About 3000 kL of manure would be produced in one month.

___

That's about 3 cubic meters.

A young Witch flew her broom 48 miles form her home to a witch festival. Flying with the wind, the trip took 3 hours. Her flight
vekshin1

Using the relation between velocity, distance and time, it is found that:

  • The speed of the wind is of 2 mph.
  • The speed of the broom is of 14 mph.

<h3>What is the relation between velocity, distance and time?</h3>


Velocity is <u>distance divided by time</u>, hence:

v = \frac{d}{t}

Flying with the wind, in which v = v_b + v_w the 48-mile trip took 3 hours, hence:

v = \frac{d}{t}

v_b + v_w = \frac{48}{3}

v_b + v_w = 16

Her flight home against the wind took 4 fours, hence:

v = \frac{d}{t}

v_b - v_w = \frac{48}{4}

v_b - v_w = 12

Adding the two equations:

2v_b = 28

v_b = 14

v_b + v_w = 16 \rightarrow v_w = 2

Hence:

  • The speed of the wind is of 2 mph.
  • The speed of the broom is of 14 mph.
