Answer:
x = 64
Step-by-step explanation:
Remark
As all triangles have interior angles added up to 180o , quadrilaterals have interior angles adding up to 360. Think of a square with it's frour rightangles. 4*90 = 360
Givens
W+X+Y+Z = 360
X = 100
Y = 130
Z = 66
W = x
Solution
x + 66 + 130 + 100 = 360
x + 296 = 360
x = 360 - 296
x = 64
Answer:
y = 4.625
Step-by-step explanation:
Subtract 16.4 from both sides and collect terms.
8.4 -6.8 -16.4 = -3.2y +16.4 -16.4
-14.8 = -3.2y
Divide both sides by -3.2.
-14.8/-3.2 = (-3.2y)/-3.2
4.625 = y
The solution is y = 4.625.
No; try multiplying 0.25 w different numbers
1*.25= .25
2*.25= .5
3*.25= .75
Answer:
A - Difference in tides for location C is 6.9 feet and high tide for location A is 8.2 feet.
B - Value of low tide in location D is -0.64 feet.
Step-by-step explanation:
Part A: We are given,
The table showing the difference between high and low tides.
The difference in tides for location C = 7.34 - 0.44 = 6.9
So, the difference in tides for location C is 6.9 feet.
Also, i.e. i.e. i.e. x = 8.2
So, the high tide for location A is 8.2 feet.
Part 2: We are given, the mean of the low tides for the 4 locations is -0.54
Let, 'x' feet be the value of the low ride in location D.
That is,
That is,
That is,
That is,
That is,
That is, x = -0.64 feet
Hence, the value of low tide in location D is -0.64 feet.
