Answer:
C) No, after multiplying 15.5 by 18 you need to divide by 25 to determine the number of boxes.
Step-by-step explanation:
The dimensions of the rectangular room are 15.5 feet x 18 feet. Which is a total area of: 15.5 x 18 = 279 ft².
The tiles being used are 12 inches x 12 inches or 1 foot x 1 foot. Since there are 25 tiles in each box, it can cover an area of 25 ft ².
When doing calculations with measurements, the measurements must be the same. For instance, you can not divide square feet by inches because they are different measurements. However, you can divide by square feet. To the total square footage of the room (279 ft²) can be divided by the amount of square feet covered by each box (25 ft²): 279/25 = 11.16 or a minimum of 12 boxes would be needed.

Answer:
T = 60 degrees
Step-by-step explanation:
The dotted line is the height so it is a right angle
We are able to use trig functions since this is a right triangle
cos T = adj side / hyp
cos T = a/b
cos T = 8 sqrt(2) / 16 sqrt(2)
cos T = 1/2
Taking the inverse of each side
cos^-1 ( cosT) = cos^-1 ( 1/2)
T = 60 degrees
Answer:
$2.85
Step-by-step explanation:
The price Ellen pays can be found using the proportion ...
price/(24 oz) = $1.90/(16 oz)
Multiplying by 24 oz, we get ...
price = $1.90(24/16) = $2.85
Ellen pays $2.85 for the beans.
