Answer:

Angle COD=40

Step-by-step explanation:

(2a+62)+ (54-a)+(5a-20)=180

6a+96=180

6a=84

a=14

Angle AOC=2(14)+62=90

Angle COD=54-14=40

Angle DOB=5(14)-20=50

Answer:

Angle COD, 40 degrees

Step-by-step explanation:

Alrighty, to start, Angle AOB is a 180 degree angle because it is a line.

Therefore, if we combine all of the variables and numbers together, we can set it equal to 180 degrees to find a.

2a+62+54-a+5a-20

6a+96=180

6a=84

a=14

Next, plug in this value into each of the given angles provided with variables and numbers:

<u>Angle AOB: </u>

2a+62

2(14)+62

28+62

90 degrees

<u>Angle COD: </u>

54-a

54-14

40 degrees

<u>Angle DOB: </u>

5a-20

5(14)-20

70-20

50 degrees

<em>From this, it can be found that Angle COD has the smallest angle, with it being 40 degrees.</em>

What number is the height changing by each minute
Sveta_85 [38]

The height is changing by 0.5 each minute

<h3>How to determine the number?</h3>

The question implies that we calculate the slope of the table

From the table of values, we have the following points

(0, 150) and (1, 150.5)

The slope is then calculated as:

m = (y2 - y1)/(x2 -x1)

This gives

m = (150.5 - 150)/(1 - 0)

Evaluate

m = 0.5

Hence, the height is changing by 0.5 each minute

Candace makes a sugar-water mixture for hummingbirds. She knows the amount of sugar used in the mixture is proportional to the a
Sonja [21]

Answer:

the first image (the image with the upward sloping line)

Step-by-step explanation:

If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.

If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line

Solve the system of equations using substitution.<br> 3x + 7y = 19<br> -X + 8y = -27
Harman [31]

Answer:

x= 11

y= -2

Step-by-step explanation:

8y + 27 =x

3(8y+27) + 7y =19

24y + 81 + 7y =19

31y + 81 =19

<u>       -81    -81</u>

<u>31y</u> = <u>-62</u>

<u>31       31      </u>

y = -2

-x + 8(-2) = -27

-x - 16 = -27

<u>    +16    +16   </u>

-x = -11

x= 11
