A baker requires 21 ounces of flour to make a loaf of bread. Given that the amount of flour the baker needs, w ounces, is direct
Degger [83]

Answer:

Constant of proportionality, k = 21

w \propto n\\w = kn\\w = 21n                                      

Step-by-step explanation:

We are given the following in the question:

The amount of flour required is directly proportional to the number loaf of breads made.

Let w be the weight of flour and n be the number of loaf of breads.

Thus, we can write,

w \propto n\\w = kn

where k is the constant of proportionality.

21 ounces of flour is required to make 1 loaf of bread.

Putting these values, we get,

21 = k(1)\\\Rightarrow k = 21

Thus, the equation giving relation between weight of bread and number of loafs of bread is

w = 21n

If x=-7 is a root of the equation x^2+kx+49=0, then k=​
aleksley [76]

Answer:

k=14

Step-by-step explanation:

Given:

x^{2}+kx+49 = 0

x = -7

Substitution can be used to find the value of k:

(-7)^{2}+(-7)k+49 = 0

49-7k+49 = 0

98 -7k = 0

k = 14

Hope this helps :)
