Answer:
85.36 far north from the center
10.36 far east from the center
Step-by-step explanation:
The extra direction taken in the north side is x
X/sin(360-315)=50/sin 90
Sin 90= 1
X/sin 45= 50
X= sin45 *50
X= 0.7071*50
X= 35.355 steps
X= 35.36
Then the west direction traveled
West =√(50² - 35.355²)
West = √(2500-1249.6225)
West= √1250.3775
West= 35.36 steps
But this was taken in an opposite west direction
From the center
He is 35.36 +50
= 85.36 far north from the center
And
25-35.36=-10.36
10.36 far east from the center
The value has decreased because the amount he gets in Canadian dollars has decreased for the exact same amount he has in yuan.
I.e. Before: 12000/6.64 = 1807.23 Canadian dollars
Present: 12000/6.78 = 1769.91 Canadian dollars
Equivalent fractions for 3/4 are 6/8 and 9/12
Equivalent fractions for 4/5 is 8/10 and 12/15
Hello there!
In order to solve this system of equations, you would first need to make one equation have a negative variable.
2a + 3b = -1
(3a + 5b = -2) -1
2a + 3b = -1
-3a - 5b = 2
Now, we have to modify the equations for it to be able to cancel out a variable. To do this, you would need to look at the least common multiple.
2: 2, 4, 6, 8, 10
3: 3, 6, 9, 12, 15
One least common multiple would be 6 so let's modify the equation!
(2a + 3b = -1) 3
(-3a - 5b = 2) 2
6a + 9b = -3
-6a - 10b = 4
Now, let's cancel out the variable and solve for b.
9b = -3
-10b = 4
-1b = 1
b = -1
In order to solve for a, just plug in the b into one equation and solve for a.
2a + 3(-1) = -1
2a - 3 = -1
2a = 2
a = 1
The answer would be a = 1 and b = -1
Answer:
Step-by-step explanation:
Use the formula for area of a circle
A = 
The diameter is 8ft, if there was only a line from the middle to the edge of the circle, then it would be radius
The radius is half the diameter so divide 8 by two and you get the radius
Plug in the radius into the formula
A = 
the parenthesis indicate you aren't only squaring the ft, but also the 4
4ft * 4ft = 16
(remember you are also multiplying the unit, in this case feet)
A = 
there aren't parenthesis here, meaning you aren't squaring the 16
A = 50.24
