Answer:
b
Step-by-step explanation:
just took it i got 100%

We know that, in ∆ABC,
∠A+∠B+∠C = 180°
But the triangle is right angled at C
ie., ∠C = 90°
Therefore, ∠A+∠B+ 90° = 180°
⇒ ∠A + ∠B = 90°
Therefore, <u>cos(A + B) = cos 90º = 0</u>
Answer:
Step-by-step explanation:
18% tip in $=18/100 * $4.06
$0.7308
7% sales tax in $= 7/100 * $4.06
$0.2842
Total amount he paid= $0.7308+$0.2842+$4.06
$5.07500
Note:
The slope of a straight line passing through the points (x₁, y₁) and (x₂, y₂) is

The two given points are (-3,4) and (4,-1). Therefore the slope is

Answer:
37.699 cubic inches of water
Step-by-step explanation:
Volume of a cone is V= 1/3 pi r^2 h
We are given that the height is 5 in and the radius is 2 in.
Plug that into the formula: V= 1/3 pi 2^2 9
1/3 x 4 x 9 = 12
Now we are left with 12 pi.
Use a calculator and multiply 12 by pi to get:
37.699
