Name two solutions for each inequality.

ahrayia [7]

So,

#1: $n \geq 3 \frac{11}{16} + 4 \frac{1}{2}$

Convert to like improper fractions.
$n \geq \frac{59}{16} + \frac{72}{16}$

Add.
$n \geq \frac{131}{16}\ or\ 8 \frac{3}{16}$

So, one solution could be $8 \frac{3}{16}$ .

Another solution could by 9. There is also 10, 11, 12, etc., and all numbers in between.

#2: $k \ \textless \ 6 \frac{2}{5} * 15$

Convert into improper fraction form.
$k \ \textless \ \frac{32}{5} * 15$

Multiply.
$\frac{(2^5)(3)(5)}{5}$

Cross-cancel, and we have our final result.
$(2^5)(3) = 96$
k < 96

96 is not a solution.

95 is a solution.

So is 94, 93, 92, etc, and all numbers in between.

A colony of bacteria triples in link every 10 minutes. It's length is now 1 mm. How long will be in 40 minutes

Nuetrik [128]

If the bacteria is tripling every 10 minutes, that means the "rate of increase" on that period is 200%, so if say the current amount is "c", 200% of "c" is just 2c, so c + 2c is 3c, a tripled amount.

$\bf \textit{Periodic Exponential Growth}\\\\
A=I(1 + r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &1\\
r=rate\to 2\%\to \frac{200}{100}\to &2.00\\
t=\textit{elapsed time}\to &40\\
p=period\to &10
\end{cases}
\\\\\\
A=1(1 + 2)^{\frac{40}{10}}$

Drupady [299]

6785 - 6496 = 289 units
289 x 13p = 3757p
3757p = £37.57
37.57 + 21.45 = £59.02

Find what h equals please help ASAP THANK YOU! 4h-1=3h+2

Sunny_sXe [5.5K]

H = 3.

FIRST STEP:
Add 1 to both sides to get rid of the -1 on the left side.
4h-1 = 3h+2
4h-1 (+1) = 3h+2 (+1)
4h = 3h+3

SECOND (FINAL) STEP:
Subtract 3h from both sides to get rid of the 3h on the right side.
4h(-3h) = 3h+3 (-3h)
h = 3
Hope this helps, sorry if it's hard to understand :)
