Answer:

  • 3/4 - 1/4 = 1/2
  • 5/8 - 1/8 = 1/2

Step-by-step explanation:

You can pick just about any fraction with an odd numerator and find another at distance 1/2 from it.

For example, 5/7 - 1/2 = 10/14 - 7/14 = 3/14. So your subtraction problem can be ...

  5/7 - 3/14 = 1/2

Choosing a denominator divisible by 4 can make both parts of the problem use the same denominator.

  3/4 - 2/4 = 1/4, so the corresponding subtraction problem is 3/4 - 1/4 = 1/2.

  5/8 - 4/8 = 1/8, so the subtraction problem is 5/8 -1/8 = 1/2.

Answer:

The area of sector AOB is 75.36 unit²

Step-by-step explanation:

Consider the provided information.

Circle O with minor arc AB=60 degrees and OA =12.

We need to find the area of sector.

Area of the sector: A=\frac{\theta }{360} \times \pi r^2

Substitute \theta=60 and r =12 in above formula.

A=\frac{60}{360} \times 3.14\times (12)^2

=\frac{1}{6} \times 3.14\times 144

=24\times 3.14

=75.36

Hence, the area of sector AOB is 75.36 unit²

On a piece of paper, graph this system of inequalities. Then determine which region contains the solution to the system.
Mashutka [201]

we have

y\leq \frac{1}{4}x+3 ----> inequality 1

The solution of the inequality 1 is the shaded area below the solid red line

The solution is the region D and region C

y\geq-x+5 -----> inequality 2

The solution of the inequality 2 is the shaded area above the solid blue line

The solution is the region B and region C

The solution of the system is the common area

so

The solution is the region C

see the attached figure

therefore

the answer is the option C

Region C
