A pancake recipe calls for 4 1/2 cups of whole wheat flour .If the chef wants to split the recipe into 3 equal batches , how much flour should be in each batch
Answer: [tex]1\dfrac12\text{ cups}[/tex]
Step-by-step explanation:
Given : Quantity of flour required for 1 recipe = [tex]4\dfrac12[/tex] cups
[tex]=\dfrac{4\times2+1}{2}[/tex] cups
[tex]=\dfrac92[/tex] cups
Now , if chef wants to split the recipe into 3 equal batches , then quantity of flour in each batch = [tex]\dfrac92\div 3[/tex] cups
[tex]=\dfrac92\times\dfrac13\\\\=\dfrac32\text{ cups} = 1\dfrac12\text{ cups}[/tex]
Hence, the quantity of flour in each batch = [tex]1\dfrac12\text{ cups}[/tex]
Mr. Jones has 550 goats, which is 10% more than Mr. King has. How many more goats does Mr. Jones have than Mr. King?
Answer:
55
Step-by-step explanation:
Number of Jone's goats = 550
Let Number of King's goat = x
Jone's goat is 10% more than King's ;
Thus, number King's goat would be ;
x = 550 - (10% of 550)
x = 550 - 55
x = 495
x = Mr. King's goat
Hence, Jones goat is :
550 - 495 = 55 more than Mr King's goat.
Mr King has 55 goats
Number of goats owned by Mr Jones is 550
let y represent the goats owned by Mr King
y= 550-(10% × 550)
= 550- (0.1×550)
= 550 - 55
= 495
= 550-495
= 55
Hence Mr King has 55 goats than Mr Jones

The dimensions of a standard tennis court are 36 ft. × 78 ft. with a net that is 3 ft. high in the center. The court is modified for players aged 10 and under such that the dimensions are 27 ft. × 60 ft., and the same net is used. Use similarity to determine if the modified court is similar to the standard court.
Answer:
Modified court is not similar to the standard court
Step-by-step explanation:
Given that :
Dimension of standard tennis court:
36ft by 78ft
Net height = 3 ft
Dimension of Modified Court :
27ft by 60ft
Net height = 3ft
To examine similarity :
We obtain the dilation factor for width and length :
(Standard court length / modified court length)
= 36 ft / 27 ft
= 4 / 3
Width :
Standard court width / modified court width)
= 78 ft / 60 ft
= 13 / 10
Since the dilation factor for the width and length are different, then we can conclude that the standard and modified court are not similar

Tiana uses 1 3/5 oz of detergent for each full load of laundry. How many full loads of laundry can she do with 100 oz of detergent? Show your work.
Answer:
63 Full loads of laundry
Step-by-step explanation:
We have been told in the question that 1 3/5 oz or 8/5 oz of detergent is used for a full load of laundry.
So,
1 full load of laundry requires 8/5 oz of detergent
Then,
x full loads of laundry require 100 oz of detergent
100 = 8/5x
x = 100 * 5/8
x = 63 Full loads of laundry (to the nearest whole number)

In the function f(x) = (x^2 -6x + ___) + 20, what number belongs in the blank to complete the square?
Answer:
blank = -11
Step-by-step explanation:
The given function is :
[tex]f(x) = (x^2 -6x+x)+20[/tex]
We need to find the number x such that it forms the complete square.
If x = -11, then it will becomes,
[tex]f(x) = (x^2 -6x+(-11))+20\\\\f(x)=x^2-6x+9[/tex]
We can write it as follows :
[tex]f(x)=x^2-2(1)(3x)+(3)^2[/tex] ..(1)
We know that,
[tex](a-b)^2=a^2-2ab+b^2[/tex] ...(2)
Comparing (1) and (2).
[tex]f(x)=(x-3)^2[/tex]
So, if we put the blank equals -11, then it will become the perfect square.
