Mathematics

Lelu [443]2 years ago

That's easy.

There are 14 days in 2 weeks.

So we would need to multiply 9.5 x 14.

And that would be 133.

The volume of a rectangular prism is its length times width times height, or algebraically, V=lwh. You may be used to computing volume with numbers, but remember, a variable is a stand-in for a number. So you can solve this in the same way. Substitute l=x, w= \frac{x}{2},h= \frac{x}{3} into the formula for volume. You get (x)( \frac{x}{2})( \frac{x}{3} ), and you multiply these factors together. As you would with ordinary fractions, multiply the numerators and denominators across. You get \frac{(x)(x)(x)}{(1)(2)(3)} =  \frac{x^3}{6}. It seems that the book wants you to simplify by bringing the 6 up to the denominator. Recall the rule x^{-n}= \frac{1}{x^n}, if n is non-negative. The opposite applies so that \frac{1}{6} = 6^{-1}. For your final answer, you write 6^{-1}x^3. This corresponds to answer choice B.

The perimeter of a rectangle is 34 units. Its width is 6.5, point
Sliva [168]

Answer:

Length = 10.5units,Area = 68.25 unit²

Step-by-step explanation:

Perimeter =34 units

Width =6.5 units

Perimeter = l+l+w+w

Where l= length and w= width

34 = l + l + 6.5+ 6.5

34.= 2l + 13

Subtract 13 from both sides

2l = 34 - 13

2l = 21

Divide both sides by 2

L= 21/2

Length = 10.5units

If we are to find the area.

Area = length x width

Area = 10.5 × 6.5

Area = 68.25 unit²
