The angles are 72 degrees and 108 degrees.

Explanation:

Angle 1 : Angle 2 = 2 : 3
Angle 1 = 2k
Angle 2 = 3k

Angle 1 + Angle 2 = 180 (supplementary angles)
2k + 3k = 180
5k = 180
k = 36

Angle 1 = 2k = 2 x 36 = 72 degrees
Angle 2 = 3k = 3 x 36 = 108 degrees

And model links of 12 cm represents an actual length of 102 feet what is the scale for the model

babymother [125]

If there are 30.48cm in a foot and 12cm represents 102 feet then 12 cm represents 3109cm or 12:3109. Divide both sides by 12 to get the scale and it is: 1:259, the scale is 259.

Hope this helps :)

Jonathan has a bag that co rains exactly one red marble (r), one yellow marble (y) and one green marble (g). He chooses a marble

liraira [26]

Answer: The first outcome shall be 0.33 or 33%.

The second outcome would be 0.5 or 50%

Step-by-step explanation: The bag contains exactly one yellow, one red and one green marble. So when he draws the first marble the sample space shall be the total possible outcomes, which is three, since he has three (3) marbles altogether. When he draws the first time without looking, all three marbles have an equal probability of being picked which can be derived thus;

P(Red) = Number of required possibilities/Number of all possibilities

P(Red) = 1/3

P(Red) = 0.33

Note that there is only one marble of each color which means P(Yellow) and P(Green) is also 0.33 respectively.

After choosing the first marble, without replacing the first one he now chooses another marble. The sample size would have reduced to 2 (since one marble has been drawn). Hence, the outcome when he draw a second marble can be calculated as follows;

P(Red) = Number of required outcomes/Number of possible outcomes

P(Red) = 1/2

P(Red) = 0.5

Consider the relation {(−5, 8), (4, −2), (4, 1), (3, 0)} . What integer is in the domain?

Gre4nikov [31]

Question:

Consider the relation {(−5, 8), (4, −2), (4, 1), (3, 0)} . What integer is in the domain?

A 8

B -2

C -5

D -1

Answer:

Option C

The domain is -5, 4, 4, 3

Solution:

Given relation is:

${(-5, 8), (4, -2), (4, 1), (3, 0)}$

Let us understand about domain and range

Domain refers to the set of possible input values

Range is the set of possible output values

Thus the input values in given relation are:

(x, y) = (-5, 8) , (4, -2) , (4, 1) , (3, 0)

The input values are values of "x"

Input values = -5, 4, 4, 3

Thus the domain of given relation are -5, 4, 4, 3

Thus option C is correct
