Hello! So Sophia cuts two pieces of ribbon that are different lengths and lines them up together. To find the total length of the two ribbons, let's add them up. Because there is no digit in the thousandths place, we'll fill that in with a zero. Now, let's add up the numbers. 9.281 + 7.740 = 17.021. There. The total length of the ribbons is 17.021 cm long.
the area of a square = length*length =3a*3a=9a^2
Its c the answer is c because 8+4 is 12 and if you get rid of the angle and move the line so it’s straight it would be both 8 and 4
30X15=450. 450:100= 4,50. 30+4,50= 34,50
Here is the equation: (gas=g)
8.5g= 23.94
All you need to do is the inverse of multiplication on the other side. (division)
23.94/8.5= 2.81647.....
g= 2.82 (rounded to the hundredths place)
I hope this helps!
