1st rectangle:
width: 2.48cm
length: 4.96
2nd rectangle:
width: 4.96 (equals to the length of the 1st rectangle)
area: 9.92
length: 9.92/4.96 = 2
Answer:
c 120
Step-by-step explanation:
I'm thinking isit is c120
For this triangle in particular, we can use the special rules of a 30-60-90 triangle
This says:
The opposite side of 30° is: x
The opposite side of 60° is: x * sqrt(3)
The opposite side of the 90° is: 2x
We have our side length for 90° so we just have to work backwards
To find our 30° side length we must divide by 2
8/2 = 4
Which means your y = 4
Now that we have our 30° side length we can just multiple it by sqrt(3)
That means your x = 4 sqrt(3)
Rx + h = sx - k Take all with x to the LHS
Rx - sx = -k - h
x(R - s) = - k -h
x = (-k - h) / (R - s). Multiply top and bottom by -1.
x = (k + h) / (s - R)
Answer:
$140
Step-by-step explanation:
Orignal Price: $200
200 x 0.3
= 60
200 - 60
= 140
