Jessica is thinking of a number that rounds to 1,300 for the nearest ten and for the nearest hundred.what number might she be thinking of ?

Hey There!

One of the numbers she might be thinking of could be 1,298, because it rounds to 1,300 in the nearest hundreds, and for the nearest tens. Remember, when a number is greater than 5 you round it to the nearest ten. Same rule applies for the hundreds, but the number has to be in the tens place instead of the ones place.

64 is the missing number

1 is the distance between each x value

The ratio is 1:4

Step-by-step explanation:

You can figure out the ratio between the y values by taken one and divided it by the one next to it 16/4 and 1024/256 both equal 4 so you know the scale factor is 4.

the first one is 1:4 and thats as simplified as you get so the ratio is 1:4

Then 4 times 4=16 the ratio is 4:16, simplify that and you get 1:4.

16 times 4 is 64 so that is in the blank number and that ratio is 16:64 and if you simplify that, it is also 1:4
