Answer:

1/2

Step-by-step explanation:

First count how many sections aren't red or green: 2 yellow + 2 blue

Now we know that the total number of sections is 8.

So out of those 8 sections, 2 yellow + 2 blue aren't red or green.

That is, 4 out of the 8 sections aren't red or green.

This can be expressed as a fraction: 4/8

Now we simplify the fraction by dividing by 4 on the top and bottom: 1/2

Answer:

1/2

(This is assuming all sectors are congruent)

Step-by-step explanation:

Well the other two colors that aren't red or green is blue and yellow.

There are 2 blues and 2 yellows.

There are 8 sections altogether.

We are asked to find the probability that our spinner will land on blue or yellow so we do (blue+yellow)/all = (2+2)/8=4/8=1/2.

This probability was assuming all sectors were congruent sectors.

v = speed of object meters per second

t = 3 seconds

3 = 1/2 √v
3 * 2 = √v
6 = √v
6² = √v²
36 meters = v

v = 36 meters per second

F(x)=-2x^2-2x+10 f(x)=−2x 2 −2x+10 \text{Find }f(2) Find f(2)
romanna [79]

Given that:

f(x) = -2x²-2x+10

f(2) = -2(2)²-2(2)+10

= -2(2*2) - 4 + 10

= -2(4) - 4 + 10

= -8 - 4 + 10

= -12 + 10

= -2 Ans.

I need help with this:What is the value of y? Enter your answer in the box. y =
lina2011 [118]

Answer:

y=5 degrees

Step-by-step explanation:

It is an isosceles triangle so that means that there are two angles that equal 75, so that means the third side with 4y + 10 is equal to 30 degrees.

4y+10=30

4y=20

y=5 degrees
