An example would be

8/12 - 4/12 = 4/12

8/12 + 4/12 = 12/12 = 1


Another example would be

13/24 - 9/24 = 4/24 = 1/6

13/24 + 9/24 = 22/24 = 11/12

Lastly, another example is:

4/6 - 3/6 = 1/6

4/6 + 3/6 = 7/6 = 1 1/6

If a angle is 4 times bigger than its supplement what will its measure be
Ne4ueva [31]
Supplementary angles mean that two angles equal to 180°.

Let us assume the 2 angles are angle A and angle B.

Angle A is 4 times bigger than Angle B, the supplement.

Let Angle B be represented by x.

Angle A is 4x ; Angle B is x.

4x + x = 180°
5x = 180°
x = 180°/5
x = 36°  This is the measure of angle B.

4x = 4(36°) = 144° This is the measure of angle A.

4x + x = 180°
144° + 36° = 180°
180° = 180°

Need help on precalculus
murzikaleks [220]

Answer:

arc = 15π

Step-by-step explanation:

The arc is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{225}{360} ( r is the radius )

given diameter = 24 then r = 24 ÷ 2 = 12

arc = 2π × 12 × \frac{5}{8}

     = 24π × \frac{5}{8}

     = 3π × 5

    = 15π

What is the slope of the line that passes through the points (-2,5) and (3,-4) in the standard (x,y) coordinate plane
Scorpion4ik [409]

To find the slope between two coordinates, you use the formula:

m = y2 - y1/x2 - x1

If coordinate A is (-2, 5) and coordinate B is (3, -4), then:

y2 = -4

y1 = 5

x2 = 3

x1 = -2

So, just substitute the points into the formula.

m = -4 - 5/3 - (-2)

m = -9/5

The slope of the line is -9/5.
