Complete the Ratio table below

can someone please do this for me and tell me how so I can do the other one pleaseeee I don't know what to do

KonstantinChe [14]

Answer:

P(green) =1/4

P(orange)=1/2

Step-by-step explanation:

I'm assuming this is probability but it\s been a while, so i'm not sure

number one is a square being divided into half and then one half is being divided into quarters. (as shown by the dotted lines and right angle)

so the probablity of landing in green is 1/4, because it is one fourth of the square.

the probability of the orange is 1/2 because it is 1/2 of the square

The same logic would apply to the "circle" i can see in the next problem. 120 degrees is 1/3 of 360, 90 is 1/4, and so on.

Hope that helps.

PLEASE HELP ASAP!!!

Dimas [21]

Step-by-step explanation:

5x^2+2x=1

5x^2+2x-1=0

x=-b+/-√b^2-4ac÷2a

x=-2+/-√-2^2-(4×5×-1)÷2×5

x=-2+/+√4--20÷10

x=-2+/-√24÷10

x=-2+√24÷10 or -2-√24÷10

x=-2+4.9÷10 or -2-4.9÷10

x=2.9÷10 or -6.9÷10

x=0.29 or -0.69

The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13

shepuryov [24]

Answer:

Hence, the surface area of cone is:

282.6 cm^2 which is approx 283 cm^2.

Step-by-step explanation:

We are given:

The circular base of a cone has a radius of 5 centimeters.

i.e. r=5 cm.

The height of the cone is 12 centimeters

i.e. h=12 cm.

The slant height is 13 centimeters.

i.e. l=13 cm.

Now we know that the surface area(S.A.) of cone is given by:

$S.A.=\pi r(l+r)$

Hence by putting the value of l,r and π in the formula we get:

$S.A.=3.14\times 5\times (13+5)\\\\S.A.=15.7\times 18\\\\S.A.=282.6$

Hence the surface area of cone is 282.6 cm^2 which is approx 283 cm^2.

Find the exact values of the remaining five trigonometric functions of theta, suppose theta is an angle in the standard position

nexus9112 [7]

Answer:

$\sin(\theta)=60/61\text{ and } \csc(\theta)=61/60\\\cos(\theta)=11/61\text{ and } \sec(\theta)=61/11\\\tan(\theta)=60/11\text{ and } \cot(\theta)=11/60$

Step-by-step explanation:

So, we know that:

$\tan(\theta)=60/11\text{ and } 90\textdegree$

Since θ is in QI, this means that all of our trig ratios will be positive. Recall All Students Take Calculus. Since it's QI, we refer to A in All. The A tells us that all the ratios will be positive.

Now, let's figure out the remaining ratios knowing that all of them is positive. First, let's find the hypotenuse. Recall that tangent is the ratio of the opposite side to the adjacent side. So, we can use the Pythagorean Theorem to find the hypotenuse. So:

$a^2+b^2=c^2$
