A tree is 58 inches tall. how tall is it in feet and inches
mart [117]
A foot is 12 inches.
12 can go into 58 evenly 4 times, since 12• 4 equals 48 but 12 • 5 equals 60. This means that the tree is at least 4 feet. Then to find the leftover inches we do 58-48 equals 10, therefore the answer is 58 inches translates to 4 feet and 10 inches.

Help Pls! It's for my Math 4! Scalar Multiplication!
prohojiy [21]

Answer:

Concept: Physics Qualitative Analysis.

  • Scalar values are constant and compared to vector values they do not have a direction or magnitude or a gradient representation.
  1. Lets get started by setting up the equation
  2. They want us to find 3U-2V
  3. Given U= <6,6> V=<6,-6>
  4. Now we plug in and solve!
  5. 3<6,6>- 2<6,-6>
  6. <18,18>-<12,-12>
  7. Subtract
  8. <18-12,18-(-12)>
  9. Hence that gives us a result of <6,30>
  10. Now with the skills you gained solve the rest!!!
