1. 14 loaves are needed for 63 customers

2.  90 loaves

3. 4.5 loaf

Step by Step:

9/2= 4.5

4.5x4= 18

27/4.5=6

14x4.5=63

I multiplied and divided everything by 4.5 so one loaf of bread is 4.5.

(Correct me if I'm wrong)

I hope this helped! :)

Values of k for which the quadratic equation 2x - kx + k 0 has equal roots is
WARRIOR [948]

Answer:

The answer is D.

Step-by-step explanation:

We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :

D =  {b}^{2}  - 4ac

let   \: D = 0 ,a = 2,b = k,c = k

0 =  {k}^{2}  - 4(2)(k)

{k}^{2}  - 8k = 0

k(k - 8) = 0

k = 0

k - 8 = 0

k = 8

A box has a perimeter of 27 1/2 ft. if the lenght is 9 ft. what is the area?
gavmur [86]

Answer:

Perimeter = (Length x 2) + (Width x 2)

27.5 = (9 x 2) + (Width x 2)

27.5 = 18 + (Width x 2)

9.5 = (Width x 2)

4.75 = Width

check:

27.5 = (9 x 2) + (4.75 x 2)

27.5 = 18 + 9.5

27.5 = 27.5

Since the width is 4.75 and the length is 9, we can multiply the two to get the area. 4.75 x 9 = 42.75 sq. ft.
