Answer:
Sound requires a material medium to travel , the sound through each medium through its molecules and particles present in it .Sound travels with some speed and it's speed depends upon the nature of the medium through which it travels i.e. upon density and transparently. Speed of increases with the increase in density and decreases with the increases in temperature . Speed if sound us maximum for solid then for liquid and minimum in gases because of it's large intermolecular spaces and low density.
Answer:
The perimeter of the isosceles triangle is 32 centimeters
Step-by-step explanation:
<em>The perimeter of any figure is </em><em>the sum of the lengths of outline sides</em>
Let us use this fact to solve our question
∵ The perimeter of the triangle is the sum of the lengths of its 3 sides
∵ The triangle is an isosceles triangle
∵ The length of each two equal sides is 12 centimeters
∵ The length of the third side is 8 centimeters
→ Add the lengths of the 3 sides
∴ The perimeter of the triangle = 12 + 12 + 8
∴ The perimeter of the triangle = 32 centimeters
∴ The perimeter of the isosceles triangle is 32 centimeters

Answer:

Step-by-step explanation:
Hi there!
We're given that there are 8 marbles in total. 2 marbles are yellow and 3 are red, making the number of red AND yellow marbles 5 (2+3=5)
Because 5 out of the 8 marbles are yellow or red, the probability of choosing one of them is
.

Just put 4 as x in the equation and solve it. The new equation is:
sqrt(2*4)+1+3 = 0
Now we can solve it.
sqrt(2*4) becomes sqrt8:
sqrt8+1+3=0. -------> sqrt8+4=0
The sqrt of 8 is about 2.83.. so 2.83+4 is:
6.83
So we have 6.83 as the answer
but 6.83 does not equal 0 so x cannot equal 4
