Cos28=11/x
x=11/cos28
it will be c
Answer:37.2 sec
Step-by-step explanation:
Given
Joel takes 81 sec for 14 mile long track
speed of joel
mi/min=10.37 mi/min
Jason takes 69 sec for 14 mi track
so jason speed is 
if both starts from same spot in opposite direction then

where x is distance covered by Joel
then x=6.44 miles
therefore time required

Yes, for every value of x, there is only one value of y. This means that y is a function of x.
The opposite angles equal each other, so X and Z are equal
using that we solve for x by setting them equal:
6x-60 = 2x+68
subtract 2x from each side:
4x -60 = 68
add 60 to each side:
4x = 128
divide both sides by 4
x = 128/4
x = 32
now we know x so we can solve everything else by replacing x with 32
WY = 3x+5 = 3(32)+5 = 96+5 = 101
angle Z = 2x+68 = 2(32)+68 = 64+132
the answer is C
Answer:
h (1) = $140
Step-by-step explanation:
10x + 150
-10 -10
150-10
=140
so the answer must be $140
