Mrs. Beck buys 48 pieces of house siding. Each piece is 3.7 meters long. Which equation represents the best estimate for the total length of siding Mrs. Beck buys? A. 40 × 3 = 120 meters B. 40 × 4 = 160 meters C. 50 × 4 = 200 meters D. 50 × 5 = 250 meters

C. 50 × 4 = 200 meters

Step-by-step explanation:

Best Estimate involves rounding up the numbers

Mrs. Beck buys 48 pieces of house siding.

Rounding up to the nearest whole number

= 50 pieces

Each piece is 3.7 meters long.

Rounding up to the nearest whole number

= 4.0 meters long

Hence,

50 pieces × 4 meters = 200 meters

Option C is correct

the answer is true.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
