Answer:

Option A

Step-by-step explanation:

Exponent Law: In exponent division, if base are same, subtract the powers

\sf \dfrac{a^m}{a^n}=a^{m-n}

\sf \dfrac{1}{3}-\dfrac{1}{4}=\dfrac{1*4}{3*4}-\dfrac{1*3}{4*3}

          \sf =\dfrac{4}{12}-\dfrac{3}{12}\\\\=\dfrac{1}{12}

\sf \dfrac{a^{\frac{1}{3}}}{a^{\frac{1}{4}}}=a^{\frac{1}{3}-\frac{1}{4}}

     =a^{\frac{1}{12}}

Answer:

Option A :- \sf {a}^{\frac{1}{12}}

Step-by-step explanation:

\hookrightarrow \sf \:  \frac{ {a}^{ \frac{1}{3} } }{ {a}^{ \frac{1}{4} } }

Simplify the expression

\hookrightarrow \sf \:  {a}^{ \frac{1}{3} -  \frac{1}{4}  }

Transform the Expression

\hookrightarrow \sf \:  {a}^{ \frac{4 - 3}{12}  }

Calculate

\hookrightarrow \sf {a}^{\frac{1}{12}}

The area of a triangle is 20 cm², and the
grandymaker [24]

Answer:

Heavenly,  we need the forumula for the area of a triangle, do you know it?

Step-by-step explanation:

Area of a triangle is (1/2 ) * B*H

where B = base

H = height

then

A = 1/2* B * H

A is given to be 20

B = b

H = b+4

plug all those into the formula,

20 = (1/2)*b*(b+4)

use your algebra skillz  :P

20 = 1/2 *( b^{2} + 4b)

20*2 = b^{2} + 4b

40 = b^{2} + 4b

0 = b^{2} + 4b-40

rewrite the above so it's in x format

x^{2} + 4x -40 = 0

use the quadratic formula to find  x  , and for our problem, remember that x represents the base,  or b,  but don't mix it up with the b in the quadatic fomula,  with the b of the triangle, which is the base,  they are differnt "b"s   :P

X = (b±\sqrt{b^{2}-4*a*c } ) / 2*a

a = 1

b = 4

c = -40

x = (4±\sqrt{4^{2}-4*1*(-40) }  ) /2*1

x = ( 4±\sqrt{16+160} ) / 2

x = (4±\sqrt{176} ) / 2

x = (4±13.266499)/2

x= 2±6.633249

x = 2 + 6.633249 = 8.633

b= 8.633 cm

Eric plans to rent a car for a day from Easy Car Rental. He has a coupon for 25% off the daily base rate of $40. He will also ha
Volgvan
In this situation, there are 2 separate terms (parts of the story).  The first part is the information about the coupon that applies to the daily rate of $40.  You will represent this as 0.75 (for the 75% that you will be paying) x 40.  (The other part of this story is that you are paying $0.15 per mile which is represented as 0.15m.  You need to put these together to get 0.75(40) + 0.15m.  The 0.25 times 40 can be simplified to say 30, so write it as $30 + $0.15m.

Nadusha1986 [10]

Answer:

Step-by-step explanation:

sqrt(28): sqrt(4*7)

sqrt(4) = 2;

sqrt28)=2*sqrt(7)

sqrt(343): sqrt(7 * 7 * 7) = 7 * sqrt(7)

Note: the rule is if you have 3 equal primes under the root sign, you leave one, you throw one away, and you put one outside the root sign.

2 sqrt(63) = 2 sqrt(3*3*7)  The above rule gets modified to throw 1 three away and take the other one outside the root sign.

2sqrt(63) = 2*3 sqrt(7)

Numerator: 2*sqrt(7) + 7sqrt(7) = 9sqrt(7)

9sqrt(7)

======

6 sqrt(7)

3/2

Note without brackets I cannot be certain that I have interpreted this correctly. The division only apply to sqrt(343) / 2 sqrt(63). If this is so please leave a note.
