Answer:

Fraction Form: \frac{2187}{4000000}

Decimal Form: 0.000547

Step-by-step explanation:

=\frac{5}{256} * \frac{3}{5}^1^2 / \frac{3}{5}^5

\frac{3}{5}^1^2/\frac{3}{5}^5=\frac{2187}{78125}

=\frac{5}{256}*\frac{2187}{78125}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}

\frac{5*2187}{256*78125}

\mathrm{Factor\:the\:number:\:}\:78125=5\cdot \:15625

=\frac{5*2187}{256*5*15625}

\mathrm{Cancel\:the\:common\:factor:}\:5

=\frac{2187}{256*15625}

\mathrm{Multiply\:the\:numbers:}\:256\cdot \:15625=4000000

\frac{2187}{4000000}

a student has scores of 74%, 78% and 70% on three exams. What score is needed on a fourth exam for the student to earn an averag
Anna [14]

(74 + 78 + 70 + x) / 4 = 80

Divide each number by 4.

18.5 + 19.5 + 17.5 + x = 80

Add the numbers you know so far.

18.5 + 19.5 + 17.5 = 55.5

You need 24.5.

Now, since we divided all the others by 4, we have to multiply 24.5 by 4 to see what the exam score would be.

24.5 * 4 = 98.

To get an average of 80%, the student would need to get a 98 on their fourth exam.

Find all solutions to the equation (sinx-cosx)^2=3
Karo-lina-s [1.5K]

Answer:

no solutions

Step-by-step explanation:

Simplify the equation (\sin x-\cos x)^2=3:

\sin^2 x-2\sin x\cos x+\cos ^2x=3,\\ \\ (\sin^2x+\cos^2x)-2\sin x\cos x=3.\\

Since

\sin^2 x+\cos^2 x=1

and

2\sin x\cos x=\sin 2x,

we have

1-\sin 2x=3,\\ \\\sin 2x=-2.

Since \sin 2x cannot be less than -1, this equation has no solutions.
