in a certain recipe, 2 1/4 cups of flour are called for to make a cake that serves 6. of mrs. jenkins wants to use the same reci
Phoenix [80]

If in a certain recipe, a cake serving 6 persons require 2(\frac{1}{2} ) cups of flour and Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use 3(\frac{1}{3}) cups of flour.


As per the question statement, 2(\frac{1}{2} ) cups of flour are required to bake a cake that serves 6. Mrs. Jenkins wants to use the same recipe to bake a cake for 8.

We have to calculate the number of cups of flours she will need to bake her desired cake as per the same recipe.

To solve this question, we will simply use the unitary method, i.e.,

A cake serving 6 required 2(\frac{1}{2} )=\frac{5}{2} cups of flour in its preparation, then,

A cake serving 1 person will require \frac{\frac{5}{2} }{6} =\frac{5}{12} cups of flour, and finally,

A cake serving 1 person will require (\frac{5}{12} *8)=\frac{10}{3}=3(\frac{1}{3}) cups of flour.

Hence, Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use 3(\frac{1}{3}) cups of flour.

  • Unitary Method: In Mathematics, the unitary method is a problem-solving technique where, we first find the value of a single unit, and then calculate the necessary value by multiplying that single unit value.

Find the median number of magazines purchased in a store by 4 customers. 10, 55 , 34, 21
kkurt [141]
Median of  10, 55, 34, 21

First we arrange number in ascending or descending

10, 21, 34, 55  in ascending.

Median is the middle number and this is between 21 and 34.

We find the average:

(21 + 34) /2  =  55/2  =  27.5

Median is 27.5.

If a line crosses the y-axis at (0, 1) and has a slope of 4/5, what is the equation of the line?
ElenaW [278]
Using the one point format, for a slope m, and point (x₁, y₁)

y - y₁ = m(x - x₁)

Slope, m = (4/5)  point (x₁, y₁) = (0, 1),   x₁ = 0,  y₁ = 1  

y - 1 = (4/5)*(x - 0)

y - 1 = (4/5)x

y - 1 = 4x / 5

5*(y - 1) = 4x

5*y - 5*1 = 4x

5y - 5 = 4x

5y = 4x + 5 is the equation of the line.

The sum of the two numbers is 42. The smaller number is 63 less than twice the larger number. Find both numbers.
Lisa [10]
STEP 1:
identify variables and equations

x= larger number
y= smaller number

FIRST EQUATION
x + y= 42

SECOND EQUATION
y= 2x - 63


STEP 2:
substitute the y value in second equation in for y in first equation

x + y= 42
substitute y value from 2nd equation

x + (2x - 63)= 42
combine like terms

3x - 63= 42
add 63 to both sides

3x= 105
divide both sides by 3

x= 35 larger number


STEP 3:
find y value; substitute step 2 x value into either original equation

x + y= 42

35 + y= 42
subtract 35 from both sides

y= 7 smaller number


ANSWER: larger number is x= 35; smaller number is y= 7.

Hope this helps! :)
