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

Answers

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]

Maddie swims the hundred meter freestyle in 30 seconds what is her average speed in meters per minute​

Answers

Answer: 200 meters per minute

Explanation: we know that she can run 100 meters per 30 seconds. the question is asking in terms of minutes, however. we have to convert the seconds into minutes. How many minutes is 30 seconds? well, 60 seconds are in a minute so 30 seconds are in half a minute. 30 seconds = .5 minutes.

Now, we have to find how many meters she runs per minute. this means how many meters she runs in one minute. we create a proportion:

100 meters/ .5 minutes = x meters / 1 minute

we cross multiply to get 100 = .5x

then, we simplify by dividing each side by .5 which equals

200=x

Mr. Jones has 550 goats, which is 10% more than Mr. King has. How many more goats does Mr. Jones have than Mr. King?

Answers

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

Answers

After 19 hours the number of bacteria will be 193.8.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that in a lab experiment, 80 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 19 hours, to determine how many bacteria would there be after 17 hours, to the nearest whole number, the following calculation must be performed:

The number of bacteria will be calculated as,

30 x ((2/6) x 19) = X

30 x (0.34x 19) = X

30 x 6.46= X

193.8= X

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.

Answers

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)
