Answer:

$\frac{257357187500}{19683}$

Step-by-step explanation:

We can convert these mixed fractions to ordinary fractions.

$4(1/3)=\frac{(4*3)+1}{3}=\frac{13}{3}$

$3(1/3)=\frac{10}{3}$

$3(1/2)=\frac{7}{2}$

$9(3/4)=\frac{39}{4}$

Then we have:

$\frac{13}{3}*(\frac{10}{3}*\frac{7}{2})^{7}*\frac{4}{39}$

$\frac{257357187500}{19683}$

I hope it helps you!

Angle α lies in quadrant II , and tan α = <img src="https://tex.z-dn.net/?f=-%5Cfrac%7B12%7D%7B5%7D" id="TexFormula1" title="-\f

Hunter-Best [27]

Since $\alpha$ lies in quadrant II and $\beta$ lies in quadrant IV, we expect $\sin\alpha>0$ , $\cos\alpha$ , and $\sin\beta$ .

Recall the Pythagorean identities,

$\sin^2x+\cos^2x=1\iff1+\cot^2x=\csc^2x\iff\tan^2x+1=\sec^2x$

It follows that

$\sec\alpha=\dfrac1{\cos\alpha}=-\sqrt{\tan^2\alpha+1}=-\dfrac{13}5\implies\cos\alpha=-\dfrac5{13}$

$\sin\alpha=\sqrt{1-\cos^2\alpha}=\dfrac{12}{13}$

$\sin\beta=-\sqrt{1-\cos^2\beta}=-\dfrac45$

Recall the angle sum identity for sine:

$\sin(\alpha+\beta)=\sin\alpha\cos\beta+\sin\beta\cos\alpha$

So we have

$\sin(\alpha+\beta)=\dfrac{12}{13}\dfrac35+\left(-\dfrac45\right)\left(-\dfrac5{13}\right)=\boxed{\dfrac{56}{65}}$

Ken spent 1/5 of his allowance on a movie, 3/8 on snacks, and 2/7 on games. If his allowance was $20, how much did Ken have left

Lisa [10]

1/5 of 20 is $4. so 20-4=$16 remaining
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07

Answer: $6.07 is the amount ken has remaining

PLEASE HELPPPP<br><br> 4(x−2 1/4)=−3.7

LekaFEV [45]

First let’s convert the mixed numbers to improper fractions 2 1/4 =9/4
Then u get 4(X-9/4) =-3.7
Now your gonna divide both sides by four
4(X-9/4) over 4 = -3.7 over 4
4/4 =1 …X=-9/4
-3.7/4 = -0.925
Now you’re going to add 9/4 to each side
X-9/4+9/4=-0.925 +9/4
-9/4 + 9/4 =0 (X)
Now you have just -0.925 and nine fourths
I converted 9/4 —> 2.25
Then u still have -0.925
So add 2.25+-0.925 u get ur X which is 1.325 (this is ur answer)

10 - 3x < 16 <br> Can y’all help me pls

Angelina_Jolie [31]

Answer:

x>-2

Step-by-step explanation:

first you subtract 10 from both sides to find x

10-3x-10<16-10

-3x<6

now here you divide both sides by -3

-3x/-3<6/-3

BUT since you are dividing by a negative number the sign will have to flip

so the answer will be

x>-2
