Find −5 5/6÷(−4 9/10). Write your answer as a mixed number in simplest form.
uranmaximum [27]

Answer: 1\dfrac{4}{21} .

Step-by-step explanation:

Given problem : \left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)

First we convert mixed fraction into improper fractions as

-5\dfrac{5}{6}=-\dfrac{5\times6+5}{6}=-\dfrac{30+5}{6}=-\dfrac{35}{6}\\-4\dfrac{9}{10}=-\dfrac{10\times4+9}{10}=-\dfrac{40+9}{10}=-\dfrac{49}{10}

Now , plug these values in the given expression , we get

\left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)=-\dfrac{35}{6}\div\left(-\dfrac{49}{10}\right)\\\\=\dfrac{-35}{6}\times\dfrac{-10}{49}\ \ \ [\text{By Property of fraction}]\\\\=\dfrac{350}{294}\\\\=\dfrac{25}{21}=1\dfrac{4}{21}

Hence, the answer is 1\dfrac{4}{21} .

svetoff [14.1K]
When you are doing distribution with this problem you are going to get your answer of....
D) 12x^2 - 13x - 14

Steps:
Simplify...
<span>(3x + 2)(4x - 7)
= (3x + 2) (4x + -7)
= (3x)(4x) + (3x)(-7) + (2)(4x) + (2)(-7)

= 12x^2 - 21x + 8x - 14
=12x^2 - 13x -14</span>

20. Suppose you need to re-administer this injection at the point when the concentration is less than 0.5%. If the first injecti
IceJOKER [234]
Given that the function

C(h)=\frac{2h^2+5h}{h^3+8}

models the concentration of a medication in the bloodstream (as a percent), hours (h) after its injection into muscle tissue.

The number of hours it will take for the concentration of the injection to be less than 0.5% is given by:

0.5\ \textgreater \ \frac{2h^2+5h}{h^3+8} \\ \\ \Rightarrow0.5(h^3+8)\ \textgreater \ 2h^2+5h \\ \\ \Rightarrow h^3+8\ \textgreater \ 4h^2+10h \\ \\ \Rightarrow h^3-4h^2-10h+8\ \textgreater \ 0 \\ \\ \Rightarrow h\ \textgreater \ 5.54

Given that the first injection was given at 8:00 am, the time the next injection should be given is 2 pm.
