The distance on a map between a student’s house and her job is 6 cm. On the same map, the distance between her house and her school 8 cm. The actual distance from her house to school is 12 km. If d represents the approximate distance in km between her house and her job, what is d?

Answers

Answer:

9km

Step-by-step explanation:

If the distance on the map of 8cm between her house and school is equal to 12km actual distance. This means that each cm on the map represent 1.5km in actual distance (12/8=1.5).

This means that D is equal to 9km actual distance, because if each cm represents 1.5km, then 6 cm represents 9km (6x1.5=9).

What is the length of NO?
N= (7,-4)
O=(-7,-4)

Answers

Answer:

I believe it would be 14.

Step-by-step explanation:

The distance between 7 and -7 should be 14.

The length of NO is 14 units

What is the length of NO?

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the length is given by:

d =√((x2 – x1)² + (y2 – y1)²)

We:

N= (7,-4) : x1 = 7 , y1 = -4

O = (-7,-4): x2 = -7 , y2 = -4

Using the formula with the given values:

d=√((-7 – 7)² + (-4 – (-4))²)

d=√((-14 )² + (0)²)

d=√196

d= 14

Therefore, the length of NO is 14 units

Step-by-step explanation:

AB║CD  ⇒  m∠AGH  = m∠CHF = 119°   {corresponding angles}

m∠BGE = m∠AGH = 119°     {vertical angles}

m∠BGE + m∠B + m∠E = 180°     {sum of angles in triangle}

119° + 18° + m∠E = 180°

m∠E = 180° - 137° = 43°

Connor bought a baseball card eight years ago that has depreciated by $120 since he purchased it. Find the average yearly change in value of the card.

Answers

Answer:

The average yearly change in the value of the card is $15/year

Step-by-step explanation:

Here in this question, we are interested in calculating the average yearly change in the value of the card.

From the question, we can see that the value of the baseball card has depreciated by $120, thus we simply want to calculate the average yearly charge in the card value.

Mathematically, that would be ;

the total depreciation value/ number of years

From the question, the total depreciation value is $120 while the number of years is 8

Thus; the average yearly change in value of the card = 120/8 = $15/year

Write the equation of the line, with the given properties, in slope intercept form slope = -2, through(-4,7)

Answers

Answer:

y= -2x + 7

Step-by-step explanation:

So in slope intercept y will always equal something so you start with

y= mx + b

m = slope and b = y-intercept

so in this case it would first be

y = -2x + b

and then since we have the point it passes through (-4,7) we know that the line passes through the y axis at 7 hence the y value is 7.

so you finally get

y=-2x+7

The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-4, 7).

And, The slope of the line is,

⇒ m = - 2

Now,

Since, The equation of line passes through the point (- 4, 7).

And, Slope of the line is,

m = - 2

Thus, The equation of line with slope - 2 is,

⇒ y - 7 = - 2 (x - (-4))

⇒ y - 7 = - 2 (x + 4)

⇒ y - 7 = - 2x - 8

⇒ y = - 2x - 8 + 7

⇒ y = - 2x - 1

Therefore, The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

Heather is putting together a square bulletin board for her new room, and the area of the bulletin board is 196 cm2. What is the total distance around the bulletin board?

Answers

Answer:

the total distance is 56 cm

Step-by-step explanation:

Given that the area of the bulletin board is 196 cm^2

Based on this, the total distance around the bulletin board is

But before that we need to find out the side

As the area of square is

= side^2

196 = side^2

So side = 14

Now there are four sides, so the total distance is

= 4 × 14

= 56 cm

Hence, the total distance is 56 cm

10x=400+100

10x=500

divide by 10 on both sides

50 people came to the play

400+100=500
