Azmyne decided to spend 6 1/2 hours studying over the weekend. She spent 1 1/4 hours studying on Friday evening and 2 2/3 hours

nata0808 [166]

Answer: $2\ \dfrac{7}{12}\ \text{hours}$

Step-by-step explanation:

Given

Azmyne decided to study a total of $6\ \frac{1}{2}\ hours$

She spent $1\ \frac{1}{4}\ hours$ on Friday and $2\ \frac{2}{3}\ hours$ on Saturday

Hours spent on Friday

$\Rightarrow 1\ \frac{1}{4}=\frac{5}{4}\ hours$

Hours spent on Saturday

$\Rightarrow 2\ \frac{2}{3}=\frac{8}{3}\ hours$

She must study for

$\Rightarrow \dfrac{13}{2}-\dfrac{5}{4}-\dfrac{8}{3}\\\\\Rightarrow \dfrac{13\times6-5\times3-8\times4}{12}=\dfrac{78-15-32}{12}\\\\\Rightarrow \dfrac{31}{12}=2\ \frac{7}{12}\ \text{hours}$

Step-by-step explanation:

X squared or "x^2" just means X times X. For example, 9^2=81 which is the same as 9x9. Then just add 6.

How do u turn 4/10 into a fraction and percent

Delvig [45]

4/10 can be simplified to 2/5. 1/5 is equal to 20% (you probably want to memorize that) so all you have to do is multiply 20% by 2 (because of the numerator) and get 40%
So therefore 4/10 = 2/5 or 40%
P.S if you have anything over ten that needs to be a percent just multiply 10% by the numerator.

Find the rectangular coordinates of the point with the polar coordinates (3,3/2_ )

meriva

Polar coordinates: $(r,\theta)$

$r=3,\theta= \frac{3\pi}{2}$

Rectangular coordinates: $(x,y)=(r \cos{\theta},r \sin{\theta})$

$x=r \cos{\theta}=3 \cos{ \frac{3\pi}{2} }=3 \times 0=0
\\ y=r \sin{\theta}=3 \sin{ \frac{3\pi}{2} }=3 \times (-1)=-3$

Rectangular coordinates are (0,-3).
