Find the absolute value of lk-8l=8 PLS ANSWER BEFORE 6:00 TODAY TY

Bingel [31]

It's 7:58 here.

|k-8|=8

k-8 = 8 or -(k-8)=8

k=16 or -k+8=8

k=16 or k=0

check:

|0-8|=|-8|=8 good

|16-8|=|8|=8 good

Answer: k=16 or k=0

An animals heart beats 80 beats per minute how many minutes does it take to beat a million times?

Klio2033 [76]

The key calculation in this problem is figuring out how many times 80 goes into 1,000,000. I'll build up in steps here.

80 x 5 = 400. This gives us a building block on our way to 1,000,000. From here, we can go further and say that 400 x 5 = 2,000; that 2,000 x 5 = 10,000; and finally that 10,000 x 100 = 1,000,000. Altogether, starting from 80, that's

80 x 5 x 5 x 5 x 100 = 80 x 25 x 500 = 80 x 12,500

So, since 80 goes into one million 12,500 times, it takes 12,500 minutes for the animal's heart to beat that 1,000,000 times.

For 20 Points. 3 Qs. I also gave you guys a help sheet. PLEASE HELP.

Eduardwww [97]

Wat is help sheet, didn't help,

instructions unclear, got my calculator stuck in the ceiling fan

remember some simple exponential laws
$( x^{n} )(x^{m})=x^{n+m}$ and
$\frac{x^{n}}{x^{m}} =x^{ n-m }$
$x^{-m}= \frac{1}{x^{m}}$

first one
$(2^{-6})(2^{3})=2^{-6+3}=2^{-3}= \frac{1}{2^{3}} = \frac{1}{8}$

2nd one
$\frac{7^{5}}{7^{3}} =7^{ 5-3 } = 7^{2} = 49$

third one
$(3^{-4})(3^{2})=3^{-4+2}=3^{-2}= \frac{1}{3^{2}} = \frac{1}{9}$

dunno wat to do with 'help sheet'
