Answer:

The shorter piece is 4 in. long.

Step-by-step explanation:

The length of the shorter piece can be represented using x.

Thus, you can say that the longer piece is 2x (since it is twice as long as the other piece).

Since, the length of both the pieces will, for sure, add up to 1 ft, then we can say:

x + 2x = 1 ft

Which will simplify into:

3x = 1 ft (Divide both sides by 3)

x = 4 in. (Since 1 ft = 12 in., we can express it in different units unless you want a non-terminating decimal)

x = 4 in. is the length of the shorter piece since we established that x is the length of the shorter piece earlier on.

A shelf is designed so it will fit in a 90º corner between two walls. The shelf has dimensions, rounded to the nearest tenth, as

den301095 [7]

Answer:

Yes, it will fit snugly in a 90º corner

Step-by-step explanation:

To do this, we simply need to check if the given sides of the shelf is right-angled.

So, we have:

$Hypotenuse = \sqrt{242$

$Side\ 1 = Side\ 2 = 11$

To check for right-angle triangle, we make use of:

$Side\ 1^2 + Side\ 2^2 = Hypotenuse^2$

This gives:

$11^2 + 11^2 = \sqrt{242}^2$

$121 + 121 = \sqrt{242}^2$

$242 = \sqrt{242}^2$

$242 = 242$

This shows that the given sides of the shelf is a right-angled triangle.

Hence, it will fit the wall

How many different three-letter initials with none of the letters repeated can people have?

viva [34]

This is a probablity question

there are 3 slots, 26 letters of the alphabet

so in the first slot, we have 26 possible letters
2nd slot, we have 25 possible letters (we used one for the first slot)
3rd slot, we have 24 possible letters, (we used 2 for first and 2nd slot)

so in total, we have 26*25*24 or 15600 different 3 letter initials with no repeated letters
