Okay. So for this problem you need to know that a foot is 12 inches. So Chris's piece of wood will measure 3x12 inches or 36 inches.

Because the first piece is 14 inches, the other piece must be 36-14 inches long or 22 inches long.

answer: 22 inches

How do I solve for y:<br> x²y² = 12/z²
Vika [28.1K]

Answer:

Y=Srt(12xs^2/z^2)

Step-by-step explanation:

Firstly

We multiply both sides with 1/x^2

We get

Y^2=12/z^2*1/x^2

Y^2=12x^2/z^2

Next: introduce a srt root

We have

Y=srt(12x^2/z^2)

The mass of a bag of potatoes is 860 kg round to the nearest 10kg. i) Give the upper and lower bounds for the mass.
MrMuchimi

Answer:

  • Lower bound ⇒ 855 kg
  • Upper bound ⇒ 865 kg

Step-by-step explanation:

The upper bound is the highest number that a figure can be to be rounded off to the rounded figure.

The lower bound is the lowest number that a figure can be to be rounded odd to the rounded figure.

The lower bound of 860 to the nearest 10 is;

= 855 kg

855 is the lowest figure that can be rounded up to 860.

The Upper bound is;

= 865

865 is the highest figure because no figure above this can be rounded to 860.

<em>855 kg ≤ 860 kg < 865 kg</em>
