Answer:
length of corn field = (40-2x)
Breadth of corn field =(35-2x)
Perimeter of this field = 2(l+b)
<h2> P = 2(40-2x+35-2x)</h2><h2>P = 150-8x..</h2>
Answer:
Part A: 7/10
Part B: 1/2
Part C: look below*
Step-by-step explanation:
Part A:
The probablity is a 7/10 because in the previous record the gerbil went left 7 out of the 10 times
Part B:
Theoretically the gerbil has a 1/2 of going either left or right since there are two options.
Part C:
The experimental probabilty does not equal the theoretical probability because during the trial the gerbil went left 7/10 and theoretically the gerbil would go left 5/10 times.
Answer:
5040 ways
Step-by-step explanation:
That is 7 books.
So the number of ways is factorial 7 , written 7!.
= 7*6*5*4*3*2*1
= 5040 ways
Answer: -4 = <em>w OR w = -4</em>
Step-by-step explanation: For this given equation you will have to solve for the variable w. In order to do this you must isolate the variable <em>w.</em>
Step 1: Use the distributive property: -79=7w+3(4w-1) ( 3 x 4w = 12w and 3 x -1 = -3.
Step 2: Add like terms and whole numbers: -79=7w+12w-3 ( 7w + 12w = 19w
Step 3: Use the Addition Property of Equality:3 + -79=19w-3+3 ( 3 + -79 = -76 and -3 + 3 =0
Step 4: Use the division Property of Equality: -76=19w -76 divided by 19 is -4 and 19w divided by 19 is w
Step 5: The answer: -4=w
