Answer:
So, to 1 d.p. 7 is about 23% out of 30. (7 of 30=23%)
Step-by-step explanation:
7/30 x 100 =23.3333333333% or 70/3%.
This is a conversion problem. We know that 1 mile is 5280 feet, right? Since Ellie lives 2 miles, and two is double of 1, we just take 5280 and multiply that by two (or add it twice) to find how many feet is between Ellie's house and school. 5280 x 2 = 10560 (you get the same answer if you add 5280 twice). Therefore, 10560 feet lies between Ellie's house and school.

Answer:
-2
Step-by-step explanation:
The slope formula can be used. Fill in the given information and solve for b.
m = (y2 -y1)/(x2 -x1)
-3/4 = (b -4)/(6 -(-2))
-6 = b -4 . . . . . . multiply by 8
-2 = b . . . . . . . . add 4
The value of b is -2.
The number of boxes at 3 hours from the opening can be written as:
The term 52 * 3 represents the number of boxes produced in the 3 hours, so b is the initial stock.
As the sum of the boxes produced and the initial stock is 404, b is equal to 248.
To complete the table we use the relation:
Replacing the values for x, we can find the value of y:
Answer: the initial stock is 248 boxes.
