Given:
m = -8 degrees/hour, the rate of change of temperature

Let x =  hours 
Let y = temperature, °F
Then y = -8x + b
where b = constant

When x = 0, then y = b.
Therefore b = initial temperature

If the temperature drops by at least 36 °F in the next x hours, then
b - y(6) ≥ 36
b - (-8x + b) ≥ 36
8x ≥ 36
x ≥ 4.5 hours

Answer:  At least 4.5 hours

LiRa [457]

Answer:

0.33127

1. Because there's 100,000 centimeters in 1 kilometer, we have to divide the number of centimeters by 100,000.

  • 33,127/100,000
  • 0.33127

Therefore, the answer is 0.33127.

Find measure.<br> m ∠ 5
jeka57 [31]

Measure of angle 5 i.e. m∠5 = 50°

<h3>What is measurement of an angle ?</h3>

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

<h3>How to  find angle measurement ?</h3>

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Thus, m∠5 = 50°

Jane’s mobile phone plan charges $0.05 per minute at daytime rates before 8 p.m. and $0.03 per minute at nighttime rates after 8
Sonja [21]

Answer:

minutes at daytime rate: 3.00

minutes at nighttime rate: $2.70

total cost of call: $8.55

Step-by-step explanation:

split up the hours so you have the 5 cent charge per minute for 1 hour and you have the 3 cents a minute for an hour and a half after 8.

multiply 5 cents a minute by 60 to get the amount of money for the first hour($3.00),

next multiply 3cents a minute by an hour and a half (90 minutes) to get $2.70

next add the money together to get $5.70 and multiply that by 1.5 to get $8.55
