A spinner with 12 equally sized slices has 12 yellow slices. The dial is spun and stops on a slice at random. What is the

saveliy_v [14]

Answer:

1/1

Step-by-step explanation:

The reason why is because the spinner has 12 slices and on that spinner there is 12 yellow slices meaning all the slices on the spinner are yellow.

This means it is a 100% chance to land on yellow but 100% aas a fraction is 100/100.

You can simplify 100/100 a hundred times to 99/99 to 98/98 you can keep doing it but it's lowest form is the lowest number besides zero and that is 1 so it's lowest form is 1 out of 1 or 1/1 or 100%.

Hope this helps have a great afternoon:)

Your vertex is (8,7)

First find the x intercept
-2/2a

X = 16/2
X = 8

Substitute the value x and solve for y
Youd get 7

Hence
(8,7)

What is (3×10) ×8= ------ × (10×8) elementary 5th grade

Tamiku [17]

This is an example of the commutative property of multiplication.

That property states: $(a \times b) \times c = a \times (b \times c)$

So using that property, we can figure out that 3 should be in the blank.
