Solution:

<u>Note that:</u>

  • 64 × x/100 = 28

<u>Simplifying the LHS:</u>

  • 64 × x/100 = 28
  • => 64x/100 = 28

<u>Using cross multiplication:</u>

  • 64x/100 = 28
  • => 64x = 2800

<u>Divide 64 both sides.</u>

  • => x = 2800/64 = 43.75%

28 is 43.75% of 64

28 is 43.75% of 64
you can calculate this by making a fraction of 28/64 and timing this by 100!

No, in order to do the correct ratio she would have needed to add 4.5 pints to 3 pints because if you divide 9:6 by 2 it is 4.5:3 not 4:3

Changing Dimensions of 3-D Figures
Leni [432]

The prisms are congruent if the lengths of corresponding edges are in a 1:1  ratio, the volumes and the base areas are equal and the prisms have same height                                                                                                                                  

Step-by-step explanation:

For the two prisms to be congruent the following properties should hold TRUE

The lengths of corresponding edges are in a 1:1  ratio.

The volumes are equal.

The base areas are equal.

The prisms have the same height.

The owner of a cattle ranch would like to fence in a rectangular area of 3000000 m^2 and then divide it in half with a fence dow
Reika [66]
If you notice the picture below, the amount of fencing, or perimeter, that will be used will be 3w + 2l

now    \bf \begin{cases}&#10;A=l\cdot w\\\\\&#10;A=3000000\\&#10;----------\\&#10;3000000=l\cdot w\\\\&#10;\frac{3000000}{w}=l&#10;\end{cases}\qquad thus&#10;\\\\\\&#10;P=3w+2l\implies P=3w+2\left( \cfrac{3000000}{w} \right)\implies P=3w+\cfrac{6000000}{w}&#10;\\\\\\&#10;P=3w+6000000w^{-1}\\\\&#10;-----------------------------\\\\&#10;now\qquad \cfrac{dP}{dw}=3-\cfrac{6000000}{w^2}\implies \cfrac{dP}{dw}=\cfrac{3w^2-6000000}{w^2}&#10;\\\\\\&#10;\textit{so the critical points are at }&#10;\begin{cases}&#10;0=w^2\\\\&#10;0=\frac{3w^2-6000000}{w^2}&#10;\end{cases}

solve for "w", to see what critical points you get, and then run a first-derivative test on them, for the minimum

notice the 0=w^2\implies 0=w   so.  you can pretty much skip that one, though is a valid critical point, the width can't clearly be 0

so.. check the critical points on the other
