Answer && Step-by-step explanation:

Use what we know are given variables (answer choices)

we know middle is 15, 4x+7 must be > 15 plug in variables

7.5 makes it 35 but that is too big

4 is also > but it makes it slightly too big at 23 but when i divide by 3 i get 7.6, which mult 2 ~= 15

never the less, lets try it at top

4+3=7

make a triangle above 15, this will == half of 15 which is 7.5

7 is closest, I would guess 4 based on this alone.

Answer:

$The ~length~ is ~9.6~ units$ ✔︎

༄❁༄❁༄❁༄❁༄

$a=8\\b=2\\c=?\\d=?\\e=5$

$Using~ Pythagorean ~theorem:$

$c^2=a^2+b^2$

$c^2=(8)^2+(2)^2$

$\sqrt{c^2} =\sqrt{68}$

$c=\sqrt{68} ~or~2\sqrt{17}$

»»---------------------►

$d^2=c^2+e^2$

$d^2=(2\sqrt{17})^2+(5)^2$

$d^2=68+25$

$\sqrt{d^2} =\sqrt{93}$

$d=\sqrt{93} ~or~9.6$

$So, your~ answer ~is ~9.6$

According to Cavalieri’s Principle, if all of the following have the same height, which pair would NOT have the same volume? Exp

Licemer1 [7]

Answer:

Pair 2.

Step-by-step explanation:

For the volumes to be the same the base areas must also be the same.

For Pair 2 the areas are 25π and 24π while the other 2 pairs have both base areas = 25π.
