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:

214kg

Step-by-step explanation:

We can use the equation [tex]f(x)=(x)^2+18[/tex] to model the blobs growth. There are 14 days in 2 weeks so if we plug in [tex]f(14)[/tex] that will give us [tex]f(14) = (14)^2+18\\f(14)=214[/tex] so the blob will be 214kg in 2 weeks.

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.

Answer:

30

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.

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.

Explanation:

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:

Step-by-step explanation:

1⁄4 cup = 1⁄2 stick = 4 tablespoons = 2 oz. = 57g

1⁄2 cup = 1 stick = 8 tablespoons = 4 oz. (1⁄4 pound) = 113g

3⁄4 cup = 11⁄2 sticks = 12 tablespoons = 6 oz. = 170g

1 cup = 2 sticks = 16 tablespoons = 8 oz. (1⁄2 pound) = 227g

11⁄4 cups = 21⁄2 sticks = 20 tablespoons = 10 oz. = 284g

11⁄2 cups = 3 sticks = 24 tablespoons = 12 oz. (3⁄4 pound) = 341g

13⁄4 cups = 31⁄2 sticks = 28 tablespoons =14 oz. = 398g

2 cups = 4 sticks = 32 tablespoons = 16 oz. (1 pound) = 454g

The wrapping on each stick indicates tablespoon measures (8 tablespoons per stick). So if you are using cup measures you could pack the butter into a measuring cup or below is a ready reckoner which may help if you have scales. 1 stick butter = 8 tablespoons = 1/2 cup = 4 ounces/110g.

Common measurements:

1 kilogram = 2.2lbs

454 grams = 1lb = 16 oz

28.35 grams = 1 oz

1 tbsp = 15 ml

1 tsp = 5ml

1 tbsp = 3 tsp

4 tbsp = 1/4 cup

1 cup = 250ml = 8 fluid oz

1 fluid oz = 29.5 ml = 2 tbsp

1 pint = 2 cups

You could see that 4 tablespoons = 1/4, so you could pour and melt it in a measuring cup.

The coordinates of points A are -2 and 5.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

In the given image there is a rectangle ABCD on the coordinate axes. All the vertices of the rectangle are having coordinates. Point A of the rectangle is in the second quadrant where the value of y is positive but the value of x is negative. The coordinates of points A are -2 and 5.

Therefore, the coordinates of points A are -2 and 5.

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.

Answer:

y = 3x + 4

Step-by-step explanation:

Turn the equation from standard form to slope intercept form. So, solve for y.

3x - y = 2

~Subtract 3x to both sides

-y = 2 - 3x

~Divide -1 to everything

y = -2 + 3x

~Reorder

y = 3x - 2

The slope of a parallel line is the same as the original.

Find the new y-intercept.

y = 3x - 2

-2 = 3(-2) + b

-2 = -6 + b

4 = b

y = 3x + 4

Best of Luck!
