Answer:
x^9/8
Step-by-step explanation:
The exponent property that you can use here is that when multiplying the two exponents, you add their exponents
Thus, (x^7/8) (x^1/4) = x^(7/8+1/4)=x^9/8
Answer:
I think its b)1.5 seconds sorry if I am wrong
Step-by-step explanation:
16t²=time
16t²=16²seconds
16² seconds=256 seconds
16t²+64=distance
256+64=320
320 feet=distance
so
256 seconds/320feet
=1.5seconds
42.41 cubic meters
The volume of a cylinder is bh where b is the area of the base and h is the height of the cylinder. And since the area of a circle is pi r^2, we have this equation for the volume of a cylinder
V = pi*r^2*h
Now substitute, the known values for r and h, then calculate the result:
V = pi*r^2*h
V = 3.14159*3^2*1.5
V = 3.14159*9*1.5
V = 42.411465
V = 42.41
So the volume of the coal pile is 42.41 cubic meters.
Their sum can be greater than two. There is nothing that states that they couldn't be. All it states it that the two factions sums are less than 1. I hoped this helps
