Answer:120°

Step-by-step explanation:

Given

cake is cut into 12 equal pieces

We know the top view of cake is similar to circle .

So, if a circle is divided into 12 equal parts then

each part subtend an angle of

∅ = 360/12 = 30%

If 8 slices were eaten , then 4 slices are remaining

These 4 slices measure subtend equal angle at the center therefore

4 slice measure a total of 4 × ∅

➡️ 4 x 30°

➡️ 120°

If y is proportional to x and y = -15 when x = -20, what is the value of x when y = 12?
alexandr402 [8]
Maybe i have that you wanted We can represent the situation like that: Y=-15 and x=-20 Then When y=12 x=? We make x(The unknown) *-15=12*(-20) We have an simple équation to solve Thus x=(12*(-20))/-15 X=16

Line k has a slope of 2/3. If line m is parallel to line k, then it has a slope of
puteri [66]

Answer:

Line M would also have a slope of 2/3.

Step-by-step explanation:

When two line are parallel that means that they will never intersect.

In order for two lines to avoid intersection they would have to be at the same slope.

Since lines K and line M are parallel to each other they have to have the same slope.

which function rule is represented by the tablex 0 1 2 3y 0 -7 -14 -21a y= 7xb y= -7xc y= x-8d y= 7x-14
salantis [7]

The answer is y = -7x

Expalnation

Two points on the table are (0,0) and (1,-7)

Change in y = -7-0 = -7

Change in x = 1-0 = 1

Slope m of the function = -7/1= -7

Using y= mx + c

Picking point (0,0), x = 0, y = 0

y = mx + c becomes

0 = -7(0) + c

0 = 0 + c

c= 0

Hence, the equation is y = -7x + 0

which is y = -7x

Option b is the correct answer
