Answer:
With 7 cups of flour 3.13 batches of cookies can be made.
Step-by-step explanation:
The amount of flour needed per batch of cookies = 7/3 cups
= 2.33 cup
⇒ 1 batch of cookies = 2.33 cup of flour
or the ratio of <u>cookie to flour = 1 : 2.33</u>
<u />
Now, the amount of flour Benny has = 7 cups
Let the total batches of cookie made = m
or, ratio of <u>cookie to flour = m : 7</u>
So, by the RATIO OF PROPORTIONALITY:
⇒ m = 7 /2.23
or, m = 3.13
or, total batches of cookie made = 3.13
Hence, from 7 cups of flour 3.13 batches of cookies can be made.

Step-by-step explanation:
There are 5 different positions of 666:
666////
/666///
//666//
///666/
////666
The forward dashes represent any number from 0 to 9.
Case 1: "666////"
Number of ways = 10⁴ = 10,000.
Case 2: The other positions.
Since the 1st forward dash cannot be 0 (leading digit),
Number of ways for each position = 9 * 10³ = 9,000
Number of ways for all 4 positions = 9,000 * 4 = 36,000.
Total evil numbers = 10,000 + 36,000 = 46,000.
Answer:
see explanation
Step-by-step explanation:
The area (A) of a regular decagon ( 10 sided ) is calculated as
A = 0.5 × perimeter × apothem
Here side length = 3.25, hence perimeter = 10 × 3.25 = 32.5 m, thus
A = 0.5 × 32.5 × 5 = 81.25 m²
let the two numbers be x and y
From the first sentence,
xy=24
x+y=10
Then make y in equation 2 the subject of the formular and substitute in equation 1
x+y=10
y=10-x
substituting in equation 2
x(10-x)=24
open the bracket
10x-x^2=24
=-x^2+10x=24
Transfer the constant to the left hand side
=-x^2+10x-24=0
Then factorise completely
