Answer:
I tried my best to made the graph
3/-1/2
2/0/1
4/-2/3
2/0/1
1/+1/0
0/+2/1
10 pairs of 40 because 4 times 10 is 40
Answer:
Step-by-step explanation:
Do you mean multiply?
- 8/15 * 20/24
- 8/15 * 5/6
5 and 15 have a common divisor -- 5
- 8/3 * 1 / 6
8 and 6 can be divided by 2.
-4/3 * 1/3
-4 / 9
====================
You could do the same thing without cancellation.
-8/15 * 20/24 = -160 / 360
Now you can divide by common factors. Start by dividing top and bottom by 10
- 16 / 36 Now divide top and bottom by 4
- 4 / 9
A: 71+19=90 Complementary: angles add to 90
Answer: BC = 16√2 ft
Step-by-step explanation:
Triangle ABC is a right angle triangle. From the given right angle triangle, BC represents the hypotenuse of the right angle triangle.
With m∠W as the reference angle,
AB represents the adjacent side of the right angle triangle.
AC represents the opposite side of the right angle triangle.
To determine the length of BC, we would apply the Sine trigonometric ratio which is expressed as
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 45 = 16/BC
√2/2 = 16/BC
BC = 16/(√2/2) = 16 × 2/√2
BC = 32/√2
Rationalizing the denominator, it becomes
BC = 32/√2 × √2/√2
BC = 32√2/2
BC = 16√2 ft
