is 200% a whole number​

Answer: -5/6

Step-by-step explanation:

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

m=(-2-8)/(20-8)

m=-10/12

(simplify) m=-5/6

The slope value in the simplest form of a line that passes through (8, 8) and (20, -2) is:  [tex]\mathbf{-\frac{5}{6}}[/tex]

Recall:

Slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Thus:

Given two points that a line passes through as: (8, 8) and (20, -2),

(8, 8) = [tex](x_1, y_1)\\\\[/tex]

(20, -2) = [tex](x_2, y_2)[/tex]

Slope (m) = [tex]\frac{-2 - 8}{20 - 8}[/tex]

Slope (m) = [tex]\frac{-10}{12}[/tex]

Slope (m) = [tex]\mathbf{-\frac{5}{6}}[/tex]

Therefore, the slope value in the simplest form of a line that passes through (8, 8) and (20, -2) is:  [tex]\mathbf{-\frac{5}{6}}[/tex]

Answer:

Step-by-step explanation:

a) Here we have:

"In Family A, the youngest child is 7 years younger than the oldest, who is 18"

Let's define:

Y = age of the youngest child.

O = age of the oldest child.

Then we know that:

Y = O - 7

O = 18

Then we can replace the second equation into the first one:

Y = 18 - 7 = 11.

b) Here we have:

"In Family B, the middle child is 5 years older than the youngest child."

Let's define:

Y = age of the youngest child.

M = age of the middle child.

Here we have only one equation:

M = Y + 5.

Answer:

M = Y + 5.

Answer:

80%

Step-by-step explanation:

I hope this helps!

The percentage of the month of June that experiences rain is 80%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of days in June = 30.

Number of days in June that rains = 24

Now,

The percentage of days that rain in June.

= 24/30 x 100

= 80%.

Thus,

80% of the days in June rain.

Step-by-step explanation:

The value of  g(x) = 2x² - 4, when g(-2) = 4

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

Given:

g(x) = 2x² - 4

The above function is a quadratic function.

The solution of when g(-2):

Substituting the value of x = -2

 g(x) = 2x² - 4

g(x) = 2(-2)² - 4

g(x) = 8 - 4

g(x) = 4

Therefore, the value of g(-2) = 4.

Step-by-step explanation:

The car has travelled for 30 miles.

Amount of gallons in fuel tank = 16 gallons

Gas mileage = 30 miles per gallon.

Since the driver has 15 gallons left, the number of miles that the car traveled will be:

= (16miles - 15 miles) × 30

= 1 mile × 30

= 30 miles

The car travelled for 30 miles.

He cut [tex]1\dfrac{2}{3}[/tex] off of tree.

To find:

The remaining height of tree after cut.

Solution:

Initial height of tree is

[tex]7\dfrac{11}{12}=\dfrac{7\times 12+11}{12}[/tex]

[tex]7\dfrac{11}{12}=\dfrac{84+11}{12}[/tex]

[tex]1\dfrac{2}{3}=\dfrac{3+2}{3}[/tex]

[tex]1\dfrac{2}{3}=\dfrac{5}{3}[/tex]

Remaining height = Initial height - cut

[tex]=\dfrac{95}{12}-\dfrac{5}{3}[/tex]

[tex]=\dfrac{95-20}{12}[/tex]

[tex]=\dfrac{75}{12}[/tex]

Let Vc be the velocity of the car and I'm the velocity of the motorcycle. If we convert their given values, we get:

Vc = 87 km/h * 1000m / 1km * 1h / 3600s = 24.17m/s

Vm = 95 km/h * 1000m / 1km * 1h / 3600s = 26.38m/s

Since their positions are equal after 17s we can stablish that:

Where d is the initial separation distance of 54m. Solving for a, we get:

Answer:

8 km

Step-by-step explanation:

It is given that, the scale of a map says that 8 cm represents 5 km. We need  to find the  actual number of kilometers that is represented by 5 centimeters on the map.

8 cm = 5 km

1 cm = (8/5) km

For 5 cm, multiply (8/5) km by 5.

So,

x = 8 km

So, 8 km is represented by 5 centimeters on the map.

Step-by-step explanation:

-px + r = 8x -2

Step 1: Add -8x to both sides.

-px + r + -8x = 8x - 2 + -8x

-px + r - 8x = 2

Step 2: Add -r to both sides.

-px + r - 8x + -r = -2 + -r

-px - 8x = -r - 2

Step 3: Factor out variable x.

x(-p - 8) = -r - 2

Step 4: Divide both sides by -p - 8.

x(-p - 8) = -r - 2

-p - 8 -p - 8

Answer

x = r + 2

Answer:

The answer is D. A clockwise rotation of 144 degrees about the origin.

Step-by-step explanation:

In most cases; when an object is transformed, the position of the object changes. A clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.

Given:

The attached pentagon

The number of sides (n) in a pentagon is:

[tex]n = 5[/tex]

The pentagon will not be mapped onto itself when reflected across line m because m is not at the center of the polygon

The pentagon will not be mapped onto itself when reflected across the x-axis because the pentagon has 5 sides (odd number of sides)

To map the pentagon onto itself, the pentagon has to be rotated.

The angle of rotation is:

[tex]\theta = \frac{360}n[/tex]

[tex]\theta = \frac{360}5[/tex]

[tex]\theta = 72[/tex]

Other possible angles of rotation must be a multiple of 72. i.e.

[tex]\theta = 72, 144, 216, 288....[/tex]

This means that: option (d) is correct because 144 is a multiple of 72

Hence, a clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.

Perimeter is a major property of a 2D shape , It is defined as the distance covered around the shape.It is also called the length of a triangle , rectangle and square.

It has major usage in calculation of the fencing that needs to be done , revolution that is being done etc.

she needs to know the size of her yard.

As by the meaning of sod , sod is grass that rolls out on the ground, almost like carpet
