Is 19/4 feet long piano will fit on 5 feet long space?

Answers

simplify by dividing 19 by 4
the closest we can get is 16/4=4 and the remainder 3/4

so the piano is 4 and 3/4 foot long which is less than 5 so it will fit
4 go into 19 4 times which would be 16 and with 3 left over so it would be 4 3/4.

b. 52 [(8-2) - (0 - 3)]
52 +[(8-2) + (10 - 3)]
d. 52 + [(8 + 2) + (10 + 3)1
a.

Answers

Answer:

52/[(8 - 2) + (10 - 3)]

Step-by-step explanation:

Jeff earns $8 and spends $2 each week.

Each week he keeps (8 - 2).

Joe earns $10 and spends $ each week.

Each week he keeps (10 - 3).

The total amount they keep each week is

(8 - 2) + (10 - 3).

If you divide the cost of the game by the amount they keep each week, you get the number of weeks.

Answer: 52/[(8 - 2) + (10 - 3)]

Which value of K will make x^2-1/4x+k a perfect square trinomial?

Answers

For this case we have the following polynomial:
 x^2 - (1)/(4)x + k
 We suppose that we have a standard equation of the form:
 ax ^ 2 + bx + c
 To make a perfect square trinomial, we need to complete the square.
 Therefore, the value of c is:
 c = ((b)/(2))^2
 Using this definition for this case, we have:
 k = (((-1)/(4))/(2))^2
 k= ( (-1)/(8) )^2
 k = (1)/(64)
 Therefore, the perfect square trinomial is:
 x^2 - (1)/(4)x + (1)/(64)
 Answer:
 
The value of k is:
 
k = (1)/(64)
1/64, because (-1/4)/2 is -1/8, and -1/8  ^2 is 1/64
