Positive exponent? An index would imply that the base, x, had a fractional exponent.

My Dear Aunt Sally used to say, "If there's a negative exponent in your face, then flip your base!"

In other words, if the exponent is negative, take the reciprocal of the base, x → \frac{1}{x} and change the exponent to positive.

Therefore:   x^{-3} = \frac{1}{x^3}

I have cross the fraction bar line change the exponent sign.

A cafeteria manager needs to know how many apple and bananas to order. She asked students to choose either an apple or a banana
lilavasa [31]

Answer:

  48

Step-by-step explanation:

The fraction who picked apples is the rest of the students:

  1 - 5/8 = 3/8

of them.

So the number who picked apples relative to the number who picked bananas is ...

  apples/bananas = (3/8)/(5/8) = 3/5

Multiplying this by the number who picked bananas gives the number who picked apples:

  apples = bananas · 3/5 = 80·3/5 = 48

48 students picked apples.

____

<em>Alternate solution</em>

Let "a" represent the number who picked apples. The ratio of banana choosers to the total is 5/8, and there were 80 who chose bananas. That gives rise to the equation ...

  80/(80 +a) = 5/8

  640 = 400 +5a . . . . . . multiply by 8(80+a) and simplify

  240 = 5a . . . . . . . . . . . subtract 400

  240/5 = a = 48 . . . . . . divide by 5

48 students picked apples.

C=180-A-B=180-67-53=60deg.

by sine rule

b/sinB=a/sinA
b=a/sinA*sinB
=13/sin(67)*sin(53)
= 11.28

c/sinC=a/sinA
c=a/sinA*sinC
=13/sin(67)*sin(60)
= 12.23

A rectangular prism with a volume of 44 cubic units is filled with cubes with side lengths of 1/3 unit How many 1/3 unit cubes d
pickupchik [31]

Check the picture below.

so the volume of the smaller cube will just be (1/3)³.

how many of those cubes will take to fill up the larger cube?

namely

how many times does (1/3)³ go into 44?

\bf \left( \cfrac{1}{3} \right)^3\implies \cfrac{1^3}{3^3}\implies \cfrac{1}{27}\impliedby \textit{volume of the smaller cube} \\\\\\ 44\div \cfrac{1}{27}\implies \cfrac{44}{1}\div \cfrac{1}{27}\implies \cfrac{44}{1}\cdot \cfrac{27}{1}\implies 1188
