Question: The measures of the exterior angles of a polygon are x°, 2x°, 120°, 3x°, 18°, and 120°. What is the value of x?
A. 120
B. 360
C. 77
D. 17

Answers

Answer 1

9514 1404 393

Answer:

  D.  17

Step-by-step explanation:

The sum of the exterior angles of a polygon is 360°.

  x° +2x° +120° +3x° +18° +120° = 360°

  6x +258 = 360 . . . . . . . collect terms, divide by °

  6x = 102 . . . . . . . . . subtract 258

  x = 17 . . . . . . . . divide by 6

What's 12/15 closest to 0,1/2 or 1

Answers

Answer:

1

Step-by-step explanation:

12/15 can be simplified as 4/5, 4/5 can be rewritten as 8/10, or 80%. 0 is of course 0%, 1/2 is 50%, and 1 is 100%. 80% is closest to 100%, so 12/15 is closest to 1.

What is the slope of a line?

The slope of a line indicates the direction and the steepness of the line. The formula for the slope of a line passing through the points (x₁,y₁) and (x₂, y₂) is m = (y₂-y₁)/(x₂-x₁).

Consider the two points (1,15) and (2,11).

The rate of change of the function is nothing but the slope of the line passing through the points (1,15) and (2,11) which is:

m = (11 - 15)/(2 -1)

m = -4

Hence, the rate of change of the function is -4.

Answer:Time = 1/9 Hours  0r  0.11111 hours

Step-by-step explanation:

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted. Since then, it has grown approximately 0.5 centimeter per day.
a. Write a rule to describe the function.
b. After how many days will the zucchini plant be 0.195 meter tall?


A. h(d) = 12d + 0.5; 1.3 days


B. h(d) = 0.5d +12; 15 days


C. h(d) = 0.5d; 39 days

D. h(d) = d/0.5 = 12; 4 days

Answers

Answer:

B. h(d) = 0.5d +12; 15 days

Step-by-step explanation:

here they want to write an equation to describe the growth of the plant.  set y = height of the plant (in cm).  set x = days (since planting).  the plant was planted on day 0 (x=0).  We know that the plant was 12 cm tall when it was first planted, so we know that y(0) = 12 cm.  y(0) just means the value of the equation y when x = 0, or y(x=0), or just y(0).  Every day the plant grows .5 cm so we know the value of y will increase at .5cm for every x days, or .5x.  Add the initial value of y (where x=0) and you have the equation y = 12 + .5x  (in cm).  usually we write equations in meters and not cm, so you can change it to y = .12 +.005x (in meters).  

now just set your equation equal to .185 meters and solve for x

.185 = .12 + .005x

.065 = .005x

x = 13 days

Answer

(a) Find out the  a rule to describe the function.

To prove

Let us assume that the days be represted by d .

Let us assume that the height of plant be represted by y.

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

Than the function becomes

y = 12 + 0.5 × d

y = 12 + 0.5d

(b) Find out after how many days will the zucchini plant be 0.195 meter tall .

To prove

Let us assume that the days be represted by d .

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

As

1meter = 100cm

0.195 meter convert into centimeter.

= 19.5cm

Than the equation becomes

12 + 0.5d = 19.5

0.5d = -12 + 19.5

0.5d = 7.5

d = 15 days

Therefore 15 days will the zucchini plant be 0.195 meter tall .

a) 12 + 0.5d               d=day

b) 0.195/0.5=0.39d

Answer:

15 days will the zucchini plant be 0.195 meter tall .

Step-by-step explanation:

(a) Find out the  a rule to describe the function.

To prove  

Let us assume that the days be represted by d .

Let us assume that the height of plant be represted by y.

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.  

it has grown approximately 0.5 centimeter per day.

Than the function becomes

y = 12 + 0.5 × d

y = 12 + 0.5d

(b) Find out after how many days will the zucchini plant be 0.195 meter tall .

To prove  

Let us assume that the days be represted by d .

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

As

1meter = 100cm

0.195 meter convert into centimeter.

= 19.5cm

Than the equation becomes

12 + 0.5d = 19.5

0.5d = -12 + 19.5  

0.5d = 7.5

d = \frac{7.5}{0.5}

d = 15 days  

Therefore 15 days will the zucchini plant be 0.195 meter tall .

Over the seven-year span of babysitting for the Millard's, Carrie's babysitting rate went from $8 per hour to $14 per hour. What is the percent increase? Round to the nearest percent.

Answers

Answer: 75%

Step-by-step explanation:

Over the course of seven years, Carrie went from charging the Millards $8 to charging them $14 per hour.

To calculate the percentage increase, use the following formula:

= (New price - Old Price) / Old price * 100%

= (14 - 8) / 8 * 100%

= 6/8 * 100%

= 75%

Carrie's rate went up by 75%.
