notka56 [123]

Answer:

Javier rode bike 34 minutes before lunch.


Step-by-step explanation:


Let the number of minutes Javier rode the bike after lunch be = x minutes


Then according to question number of minutes he rode the bike after lunch

= 5x-1


Total number of minutes he rode bike = 41 min

Therefore,

x+5x-1 =41


On solving


6x= 41+1 =42


Divide both side by 6 we get

x= 7


Number of minutes he ride before lunch

= 5(7)-1 = 35-1=34 min

A hot air balloon is flying at a constant speed of 20 mi/h at a bearing of N 36° E. There is a 10mi/h crosswind blowing due east
crimeas [40]

Answer:

Step-by-step explanation:

v = {[(20sin36°)i + (20cos36°)j] + 10i} mi/h

 

vE = 20sin36º + 10 = 21.76 mi/h

 

vN = 20cos36° = 16.18 mi/h

 

v = √(vE2 + vN2) = √(21.762 + 16.182) mi/h = 27.12 mi/h

 

θ = tan-1(vN/vE) = tan-1(16.18/21.76) = 36.6º north of east

The daily profit, P, of a local bakery can be calculated using the formula P=m-(250+4h) when employees work a total of h hours a
qwelly [4]

Answer:

m=665+4h

Step-by-step explanation:

Profits of the local bakery is given by

P=m-(250+4h)

where

m = Amount of money to be received

P = Profit

h = Number of hours worked

Now P = $415

So,

P+(250+4h)=m\\\Rightarrow m=P+250+4h\\\Rightarrow m=415+250+4h\\\Rightarrow m=665+4h

The equation to calculate the amount of money, m, the bakery should receive if the desired profit is $415 is m=665+4h.

Please help! Consider the sequence {20, 17, 14, 11, 8, 5, 2...}.
Sloan [31]

Answer:

c.) 38

Step-by-step explanation:

\sum\limits_{n=3}^6 a_n   means "summation of the all the elements starting from the 3rd element to the 6th element".

The 3rd element in the series is 14, and the 6th element is 5; we have to add these and all the elements between them together.

∴    \sum\limits_{n=3}^6 a_n    =  14 + 11 + 8 + 5

                   = 38
