Answers

Answer: A, C, A, B

Step-by-step explanation:

For all of these, we can use indecy laws such as when there is a power of a power, you can multiply the powers.

Using this, we get 6^-3 x -1 or,

6^3

For the second one we get (6)^-3 x 3 or,

6^ of negative 9 which is neither.

I am guessing that the last 2 are fractions. (1/6)^-3 is equal to 216 which is 6^3.

For the last one, (1/6)^3 is basically the opposite so the answer is 6^-3.

Hope this helps!

Karina is baking bread. She buys a small bag of flour that contains 2[tex]\frac{2}{3}[/tex]cups of flour. The recipe calls for 2 [tex]\frac{5}{7}[/tex]cups of flour. Does she have enough flour to bake the bread? Explain how she can compare the fractions to know for sure.

Answers

Answer:

to compare she must calculate...

1) ((2*3)+2)/3 she get 2.666

2) ((2*7)+5)/7 she get 2.714

by approximation the two are the same and she had enough flour.

Using approximation, the two are the same and she has enough flour.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Karina buys a small bag of flour that contains [tex]2\frac{2}{3}[/tex] cups of flour. The recipe calls for [tex]2\frac{5}{7}[/tex] cups of flour.

1)   [tex]2\frac{2}{3}[/tex] cups of flour.

=  ((2 x 3)+2)/3

= 2.666

Hence, she get 2.666

2)  [tex]2\frac{5}{7}[/tex]  cups of flour.

= ((2x 7)+5)/7

= 2.714

Hence, she get 2.714

Using approximation, the two are the same and she has enough flour.

Conversion a mixed number 2 2/5 to a improper fraction:-

=> 2 2/5 = 2 × 5 + 2 = 12/5

To find new numerator:

a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/5

= 10/5

b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12

c) Write a previous answer (new numerator 12) over the denominator 5.

Two and two fifths is twelve fifth

Multiple:

= 12/5 × 5/7

= 12 × 5/5 × 7

= 60/35

= 12 × 5/7 × 5

= 12/7

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(60, 35) = 5. In the next intermediate step, , cancel by a common factor of 5 gives 12/7

12/7 in mixed fraction is 1 5/7

the answer is is 1 5/7
