Answer:
6.
Step-by-step explanation:
We can start by defining a couple things.
x = amount of nickels
y = amount of dimes
Since he has the same amount of each, we can say this.
x = y
And because we know it totals 0.90, we can say this.
0.05x + 0.10y = 0.90
then, we substitute and get this.
0.05x + 0.10x = 0.90
Simplify.
0.15x = 0.90
Divide both sides by 0.15.
x = 6
So we have 6 nickels, and they both are the same, so we have 6 dimes.
Answer:
9 inches.
Step-by-step explanation:
Fun question! The length of a space diagonal for a cube is ![\sqrt{3*sidelength^2}](https://tex.z-dn.net/?f=%5Csqrt%7B3%2Asidelength%5E2%7D)
Thus, the first cube has a side diagonal of ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
The next cube would have a side diagonal of 3
The third cube would have a side diagonal of ![3\sqrt{3}](https://tex.z-dn.net/?f=3%5Csqrt%7B3%7D)
And the fourth cube would have a side diagonal of 9.
Since the fifth cube has a side length equal to the side diagonal of the fourth cube, it should be 9 inches.
