If a varies directly as b, and a = 28 when b = 7, find b when a = 5.

Jlenok [28]

Answer:

Value of b = $\frac{5}{4}$ =1.25.

Step-by-step explanation:

Direct Variation states that a relationship between two variables in which one is a constant multiple of the other.

*if one variable changes the other changes in proportion to the first.

*If a is directly proportional to b i.e,

$a \propto b$ then it is of the form

a = kb ;where k is constant variation.

Given: a varies directly as b;

then, by definition of direct variation;

we have;

$a = kb$ .....[1]

Substitute the value of a =28 and b =7 to solve for k;

$28 = k(7)$

Divide both sides by 7 we have;

$\frac{28}{7}=\frac{7k}{7}$

Simplify:

k =4

now, find b using same method when a =5;

then;

after substituting the value of a = 5 and k=4 in [1] ;

$5=(4)b$

Divide by 4 to both sides we get;

$b =\frac{5}{4}$

Therefore, the value of b = $\frac{5}{4}$ =1.25

NemiM [27]

$\frac{1}{6}$ or 0.167 pounds more butter was used than sugar

Solution:

Given that, Desmond's Desserts made a batch of fresh scones with 2/3 of a pound of butter and 1/2 of a pound of sugar

To find: Amount of butter used than sugar

From given information,

$\text{Butter used} = \frac{2}{3} \text{ pound }$

$\text{Sugar used } = \frac{1}{2} \text{ pound }$

To find how much butter is used than sugar, find the difference between them

$Difference = Butter\ used - Sugar\ used$

$Difference = \frac{2}{3} - \frac{1}{2}\\\\Difference = \frac{2 \times 2-1 \times 3}{3 \times 2}\\\\Difference =\frac{4-3}{6}\\\\Difference =\frac{1}{6} = 0.167\\\\$

Thus $\frac{1}{6}$ or 0.167 pounds more butter was used than sugar
