Answer:A 1st graph
Step-by-step explanation:
Using the Pythagorean theorem:
90^2 +90^2 = X^2
8100 + 8100 = x^2
16,200 = x^2
X = √16,200
X = 127.28 feet.
Rounded to the nearest foot = 127 feet.
Answer:
The primary reason for converting numbers into scientific notation is to make calculations with unusually large or small numbers less cumbersome. Because zeros are no longer used to set the decimal point, all of the digits in a number in scientific notation are significant.
Answer:
56
Step-by-step explanation:
First, I drew picture of a line containing points W and Z.
Next, I added a midpoint between W and Z and labelled it Y.
Next, I added a midpoint between W and Y and labelled it X.
It is given that XY = 14, so that means WX is also 14 (because X is the midpoint, these two distances have to the be the same)
Now I know WY is 28, which means YZ is also 28.
So WZ has to be 56.
5.63 will round to 6 if rounding to the nearest whole number or 5.6 if rounding to the nearest tenth. Hope this helps!!
