a living room measures 24 feet by 15 feet an adjacent square dining room measures 13 feet on each side if carpet cost 6.98 per square what's the total cost of the carpet in both of the rooms

Answers

the answer is $3,692.42

Final answer:

The total cost of carpeting both the living room (24 feet by 15 feet) and the adjacent square dining room (13 feet by 13 feet) at $6.98 per square foot would amount to $3692.42.

Explanation:

To find the total cost of the carpet in both rooms, we first need to calculate the total area of both rooms. The area of a rectangle is calculated by multiplying length by width, so the area of the living room would be 24 feet * 15 feet = 360 square feet. A square's area is calculated by squaring one of its sides, so the dining room's area would be 13 feet * 13 feet = 169 square feet. Adding these two areas together, we get a combined area of 360 + 169 = 529 square feet.

Next, we find the total cost by multiplying the combined area by the cost per square foot. So, the total cost would be 529 square feet * $6.98 = $3692.42

Sue wants to know how many families in her small neighborhood of 50 homes would volunteer to help at a neighborhood animal shelter. She put all the addresses in a bag and drew a random sample of 25 addresses. She then asked those families if they would volunteer to help at the shelter. She found that 18% of the families would volunteer to help at the shelter. She claims that 18% of the neighborhood families would be expected to help at the animal shelter. Is this a valid inference?A Yes, this is a valid inference because the 25 families speak for the whole neighborhood

Is 31.010 greater or less or equal to 31.01

Answers


Well, lets look at it  this way ... tell me if this does anything for you:

-- Take the number  31.01 .

-- Stick a zero on the end and make it  31.010 .

-- Zeros at the end of a number after the decimal point don't change
the value of the number.  So you haven't changed the value of  31.01 .

-- But now it looks exactly like the other number !

-- They must be equal.


Does this float your boat at all ?

31.010 is = to 31.01

the reason being that the 0 on the end of 31.010 is just there for to hold an unwanted place value.

Ex. 0.70 is the same as 0.7 because the zero is just holding a place value. It's not wrong to put in the zero but its better if you don't.
