Answer:
t is approximately 10.41 seconds
Step-by-step explanation:
s = 16t^2
1734 = 16t^2
divide by 16
1734/16 = 16t^2/16
1734/16 = t^2
take the square root of each side
sqrt(1734/16) = sqrt(t^2)
we only take the positive square root because time must be positive
sqrt(1734/16) = t
t is approximately 10.41 seconds
yesenia has 9 blocks. misty has 15.
15 + 9 = 22.
for the values of the blocks, yesenia has 17 and misty has 68.
17 + 68 = 85.
hope i helped!
Answer:
x = 4√7
Step-by-step explanation:
You can use the pythagorean theorem which is a² + b² = c²
if you plug it in, it would be...
x² + 12² = 16²
x² + 144 = 256, subtract 144 to both sides
x² = 112, square root both sides to make x by itself.
x = 4√7
I hope this is what you're looking for. The concept of regrouping<span> (borrowing) is so that students can see what actually happens in it. For example, to </span>subtract <span>52 − 38, we write 52 as 50 + 2 (breaking it down into its tens and ones). Then, </span>regrouping<span> means that 50 + 2 becomes 40 + 12.</span>
