HELP 60 PTS Write ln⁡〖(a^2 b^3)/cd〗 in expanded form. SHOW ALL WORK TO RECEIVE CREDIT.
Vinil7 [7]

Answer:

\frac{(a*a)(b*b*b)}{c*d}

Step-by-step explanation:

\frac{a^{2} * b^{3}}{cd}

A number to an exponent is the number times itself. A number to the "n"th power would be that number times itself "n" times.

This means that the fraction above could also be expressed as;

\frac{(a*a)(b*b*b)}{c*d}

If these parameters, "a", "b", "c", and "d" are given a value, then one can solve this equation.

1. Write the fraction 8/9 as a percent. Round to the nearest hundredth of a percent where necessary. A. 88.89% B. 1.13% C. 44.44
Nadusha1986 [10]

Answer:

1.A. 88.89

2.B.6.3%

3.C.64.92%

Step-by-step explanation:

1.\frac{8}{9}=0.8888

to covert it into percentage multiply it with 100

then it becomes 88.888

rounding off to the nearest hundred it becomes 88.89

2. to convert into percentage multiply it with 100

therefore 0.063×100=6.3%

3. to find percentage

    %= (no of students using mobile / total no of students )× 100

       = \frac{792}{1200}×100

       =64.918

Rounding off to nearest hundred it becomes 64.92%

92 = -4(2r - 5)<br><br> r = ?<br> Help!
Roman55 [17]

Hello there!

92 = -4(2r - 5)\\

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to switch sides.

-4(2r-5)=92

Then you divide by -4 from both sides of the equation.

\frac{-4(2r-5)}{-4}=\frac{92}{-4}

Simplify

2r-5=-23

Next you had to add by 5 from both sides of the equation.

2r-5+5=-23+5

Simplify

2r=-18

You can also divide by 2 from both sides of the equation.

\frac{2r}{2}=\frac{-18}{2}

Simplify it should be the correct answer.

r=-9

<u><em>Answer⇒⇒⇒⇒⇒r=-9</em></u>

Hope this helps!

Please help me and explain why it’s the answer
babymother [125]

Answer:

The answer is 1x+13.

Step-by-step explanation:

The reason for this is that if you put in the numbers for x you get y.

1(0)+13=13

1(1)+13=14

1(2)+13=15

1(3)+13=16
