mate the probability that at least one of the 4 batteries in his toy will go dead before 15 hours are up. Noah wants to use a spinner with equal-sized sections to represent each battery’s chance of lasting more than 15 hours. He will use red sections to represent a battery that dies before 15 hours are up and green sections to represent batteries that last more than 15 hours. How many of each section should Noah have in his spinner? Explain.

The perimeter of the triangle is 13 inches. What is the length of the shortest side?
netineya [11]

Answer:

shortest side = 3 in

Step-by-step explanation:

Sum the 3 sides and equate to 13, that is

x - 5 + 6 + \frac{x}{2} = 13, that is

x + 1 + \frac{x}{2} = 13 ( subtract 1 from both sides )

x + \frac{x}{2} = 12 ( multiply through by 2 to clear the fraction )

2x + x = 24

3x = 24 ( divide both sides by 3 )

x = 8

Thus

x - 5 = 8 - 5 = 3 and \frac{x}{2} = \frac{8}{2} = 4 , then

The shortest side is x - 5 = 3 in

How many 1-in. cubes can fit into a 2 by 4 by 2 in.<br>prism?​
wel

Answer:

16

Step-by-step explanation:

The dimensions of the base of the prism are 4" by 2"; the height is 2".

Looking at the base, we see that (4)(2), or (8) 1" cubes would cover it exactly and wholly.  We'd have a 3-dimensional prism with one layer of 1" cubes.

Now if we add a second layer right on top of the first layer, we'd have used (16) 1" cubes.
