Mathematics
1 answer:
zubka84 [21]3 years ago
8 0

Answer:

9 degrees

Step-by-step explanation:

given:

Initial temperature : 17 degrees

temperature change = reduction by 8 degrees (i.e - 8 degrees)

hence the final temperature

= initial temperature + temperature change

= 17 + (-8)

= 17 - 8

= 9 degrees

Consider the following table that describes the mass of a kitten as weeks go by. If you know the kitten grows by 10% each week f
RUDIKE [14]

Answer:

Week                   Mass  (gram)

(start)                    80

   1                         88  

   2                        96.8

   3                         106.48

   4                          117.128

Step-by-step explanation:

From the question we are told that

   The  mass of the kitten at the start week  is  m  =  80 g

   The rate at which the kitten grows is  r  =  0.10

Generally the mass of the kitten at the first  week is mathematically represented as  

    m_1 = ( r *  m)  + m

=>m_1 = ( 0.10 *  80 )  + 80      

=>m_1 = 88 \ g      

Generally the mass of the kitten at the second week is mathematically represented as  

     m_2 = ( r *  m_1)  + m_1

=>m_2 = ( 0.10 *  88 )  + 88      

=>m_2 = 96.8 \ g      

Generally the mass of the kitten at the third  week is mathematically represented as  

     m_3 = ( r *  m_2)  + m_2

=>m_3 = ( 0.10 *  96.8)  + 96.8      

=>m_3 = 106.48  \ g      

Generally the mass of the kitten at the fourth  week is mathematically represented as  

     m_4 = ( r *  m_3)  + m_2

=>m_4 = ( 0.10 *  106.48)  + 106.48      

=>m_4 = 117.128  \ g              

Week                   Mass  (gram)

(start)                    80

   1                        88  

    2                      96.8

    3                      106.48

   4                        117.128

On a particular day, the wind added 5 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 5 miles
sattari [20]

speed with no wind = s

speed with wind = s + 5

speed against wind = s - 5

time = t

speed = distance/time

distance = speed * time

With wind, time = t, speed = s + 5, distance = 50

50 = (s + 5)t

Against wind, time = t, speed = s - 5, distance = 30

30 = (s - 5)t

t = 30/(s - 5)

50 = (s + 5) * 30/(s - 5)

50(s - 5) = (s + 5) * 30

50s - 250 = 30s + 150

20s = 400

s = 20

Answer: 20 mph
