An 8 foot length of 4 inch wide crown molding costs $16. How much will it cost to buy 40 feet of crown molding?
malfutka [58]
Converting feet to inches, 8*12=96 and 96*4=384. Next, 40*12=480. Since 384*x (if x represents the cost per inch of crown molding)=16*100=1600 cents due to that for every inch, we add x amount of money, we can find x to be 1600/384=800/192=400/96=200/48=100/24=50/12=25/6 by simply dividing both the numerator and denominator by 2 each time. Since we add x amount of money for every inch, and we have 480 inches, 480*x=480*25/6=2000 cents=2000/100=20 dollars is our answer

A quiz has five true or false questions. How many possible ways could the five questions be answered?
dybincka [34]

Answer:

The total number of ways to answer = 32

Step-by-step explanation:

A quiz has five questions that can be answered as true or false.

Each question can be answered in two ways.

Lets take each question one by one.

The first question can be answered as true or false that is two ways.

Similarly each question answered in 2 ways.

To get the total number of ways, we have to multiply the number of ways for each question.

Hence the total number of questions = 2\times 2\times 2\times 2\times 2

                                     = 32

How do I solve x≤100
Molodets [167]

Answer:


Step-by-step explanation:

There's really nothing to solve here.  Rather, you should describe what x≤100 represents.

To draw an appropriate graph, draw an x-axis, mark x=100 with a black dot, and then draw an arrow to the left from this dot.  That's it.  "All x less than or equal to 100."
