Answer:
h = 6 units
Step-by-step explanation:
h = 3r
Volume = 24π
πr²h = 24π
πr² * 3r =24π
3πr³ =24π
r³ =24π / 3π
r³ = 8 = 2*2*2
r = 2 units
h = 3r = 3 *2 = 6 units
Answer:
∠B = 52°
Step-by-step explanation:
Since we know that the sum of all inner angles of the triangle equal to 180°, then we can make the following equation,
5x + 3x + 2x + 20 = 180
10x = 180 - 20
10x = 160
x = 160 / 10
x = 16
Since we know that ∠B = (2x + 20)°, we can calculate the following
∠B = (2x + 20)°
∠B = (2(16) + 20)°
∠B = (32 + 20)°
∠B = 52°
Answer:
B) p - 250
Step-by-step explanation:
Original price = p
Reduced price = p - 250.
Answer:
Step-by-step explanation:
We can first solve for the face diagonal. That is 
. Notice this will form a right triangle with the vertical side. We get that the face diagonal = 
. Now, we can use Pythagorean theorem again to get the straw length:
where s = the straw length.
We can solve that s =
