Answer:

It has a 25% chance of landing on 2

Step-by-step explanation:

If it is split into 4 equal parts each 1/4th is 25%

so landing on 2 would be 25%

S varies inversely as G. If S is 4 when G is 1.8, find S when G is 6.

Reika [66]

Given that "S" varies inversely as "G", it is an Inverse Variation Relationship. Then, it has this form:

$S=\frac{k}{G}$

Where "k" is the Constant of Variation.

Knowing that:

$S=4$

When:

$G=1.8$

You can substitute values and solve for "k":

$\begin{gathered} 4=\frac{k}{1.8} \\ \\ (4)(1.8)=k \\ \\ k=7.2 \end{gathered}$

Then, the equation that models the situation is:

$S=\frac{7.2}{G}$

Substituting this value of "G" into the equation and evaluating:

$G=6$

You get:

$S=\frac{7.2}{6}=1.2$

Hence, the answer is:

$S=1.2$

Find a measure of the missing angle<br> G<br> H<br> K<br> M

Kaylis [27]

Answer:

h = 65, g = 115, m = 49, k = 131

Step-by-step explanation:

h and 115 are supplementary angles, so 180 - 115 is 65 degrees.

g and 115 are vertical angles, so both should be 115 degrees.

m and 131 are supplementary angles, so 180 - 131 = 49 degrees.

k and 131 are vertical angles, so both should be 131 degrees.

Use the the factor theorem to determine wether the first polynomial is a factor of the second. X-3; 2x^2-4x+30

Firdavs [7]

Given the polynomial function

$P(x)=2 x^{2} -4x+30$

If (x-3) is a factor of P(x), then

$P(x)=2 x^{2} -4x+30=(x-3)*Q(x)$ , for some polynomial Q of 1st degree,

Then according to the factor theorem P(3)=0, because P(3)=(3-3)Q(x)=0*Q(3)=0.

Check

$P(3)=2 (3)^{2} -4(3)+30=18-12+30=36$ ≠0

we see that P(3) is not 0, so (x-3) is not a factor of P(x).

Which equation can be used to describe the direct variation function between E, the total earnings in dollars, and h, the number

kipiarov [429]

Let us take a sharp point for the graph.

In 4 hours total earning is $30.

Therefore, earnings per hours would be 30/4 = $7.5 per hour.

Are given direct variation between Total earnings(E) and Number of hours worked(h).

So, we can setup a direct variation as

Total earnings = Earning each hour * Number of hours.

Therefore, direct variation function would be

E=7.5*h.
