Answer:
Each cat eats a tin each day. It means 2 tins are required each day for both the cats. So, for 14 days, they will need 28 tins.
Sue has bought just 8 tins, which is not enough
Answer:
or 
Step-by-step explanation:
The question is
Find the slope intercept form of the line parallel to the line 5x+8y=120 passing through (4,5)
step 1
Find the slope of the given line
we have
isolate the variable y
The slope of the given line is m=-5/8
step 2
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the parallel line to given line is m=-5/8
step 3
Find the equation of the line into slope intercept form
The equation of the line into slope intercept form is equal to
we have
m=-5/8 and point (4,5)
substitute and solve for b
substitute

First, some housekeeping:
cos = 12/13 is incomplete; "cos" must have an argument (input).
cos x = 12/13 is fine; here "cos" has the argument (input) x.
Given that cos x = 12/13, find sin x. To do this, we'll need to find the length of the opposite side, given that the hypo length is 13 and the adj. side length is 12.
12^2 + opp^2 = 13^2, or opp^2 = 169-144 = 25.
Then the opp side could be either 5 or -5. Let's assume that it's +5, and that angle x is in the first quadrant.
Then sin x = opp / hyp = 5/13 (answer)
cos 2 is an entirely different kind of problem. Here you are told what the argument (input) to the cosine function is (it is 2, which here means 2 radians).
Using a calculator: cos 2 = -0.416. Note that the angle 2 rad is in QII, which is why the "adjacent side" is negative and also why the cos of 2 is negative.

Answer: £66</h3>
Your teacher may want you to leave off the pounds sign.
==========================================================
Explanation:
x = amount Bill gets
3x = amount Sam gets, because he gets three times as much
x+3x = 4x = total amount of money
4x = 88
x = 88/4
x = 22
Bill gets £22
3x = 3*22 = 66
Sam gets £66
Note that 22+66 = 88 to help confirm the answer.
Answer:
209.4 mm³
Step-by-step explanation:
V = (πr²h)/3
V = (200π)/3
Plug it into a calculator to get 209.4.
