Becky says that when she simplifies the following expression, the value is 6 less than her age. What is Becky's age? (7+11) - 8÷

Hitman42 [59]

(7+11) is 18, (8/2) is 4, 18-4 is 14! If this expression is 6 less than her age, she would be 20!

For the right triangle shown, the lengths of two sides are given. find the third side. leave your answer in simplified, radical

lisov135 [29]

If c is the hypotenuse and b is the leg, then the third side (a):
$a= \sqrt{c^2-b^2}= \sqrt{16^2-9^2}= \sqrt{256-81}= \sqrt{175}=5 \sqrt{7}$

If b and с are legs, then hypotenuse (a):
$a= \sqrt{b^2+c^2}= \sqrt{9^2+16^2}= \sqrt{81+256}= \sqrt{337}$

Can anyone help me out in my homework. I would love to talk about these problems

katen-ka-za [31]

Step-by-step explanation:

(b) If $F_G = m_1g,$ then

$m_1g = G\dfrac{m_1m_2}{r^2}$

Note that $m_1$ cancel out so we get

$g = G\dfrac{m_2}{r^2}$

Solving for $m_2,$ we get

$m_2 = \dfrac{gr^2}{G}$

(c) I'm not sure what the problem is asking for but here goes. As r doubles, $F_G$ becomes

$F_G = G\dfrac{m_1m_2}{(2r)^2} = \dfrac{1}{4}\left(G\dfrac{m_1m_2}{r^2}\right)$
