You need to use PEMDAS
So first you do the parenthesis.
8*1=8.
So now re-write the problem.
50+10*8+2
Now you are going to multiply.
10*=80
Now re-write the problem again.
10+80+2
10+80=90+2=92
So the answer to this problem is 92.
In the attachment is a graph of the cosine function that represents changing of the tide.
y max = 10 ft at midnight
y min = 5 ft at 6 AM
The answer is B, because if you draw the baseboards on the scale drawing, you'll get nineteen baseboards. 19 x 4,19 = 79,61
Step-by-step explanation:
gradient = slope or several other words.
it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.
it is represented by the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
in our case, when going from A to B we have
x changes by -2k (from 3k to k).
y changes by -11 (from 8 to -3).
so, the gradient or slope is
-11/-2k = 3
11/2k = 3
11 = 3×2k = 6k
k = 11/6
A = (33/6, 8) = (11/2, 8)
B = (11/6, -3)
Length times width (48) 48 convert to sq meters is around 4.45935
