Answer:

parallel line y = -1/2x + 12

perpendicular line y = 2x + 2

Step-by-step explanation:

slope = -1/2

perpendicular slope = 2

y = mx + b

10 = -1/2(4) + b

10 = -2 + b

12 = b

y = -1/2x + 12

10 = 2(4) + b

10 = 8 + b

2 = b

y = 2x + 2

Answer:

60%

Step-by-step explanation:

There are only even and odd numbers.  If a number is not even, it is odd.  If the probability of spinning an even number is 0.4, or 40%, then just subtract that by the whole spinner, which is equivalent to 100%:

100% - 40%

= 60%

This means that the odds of spinning an odd number is 60%

Answer:

d = 1.4 t + 30

Step-by-step explanation:

Head start means any advantage achieved or advantage gained in any race or competition.

In the context, the runner is gained a head start of 30 meter from the starting point.

It is also given that the speed with which the runner is running is 5.0 km per hour.

Therefore, the equation that gives the distance covered by the runner from his start line at any time in seconds is given by d = 1.4 t + 30.

Answer:

To see how these fractions are equal, I divided the numerators by the denominators. For instance, you could have 4 over 5 (4/5) and divide 4 by 5 (4/5) to get 0.8. Now you'll do the same thing for the fractions given

24/45=0.533...

8/15=0.533...

48/90=0.533...

5/9=0.5556

As you can see, the only fraction that doesn't equal 0.53, or the outlier, is 5/9 or 0.5556

Step-by-step explanation:

A fraction is a way to describe a part of a whole. The fraction that equals 0.53 is (8/15).

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The value of the given fractions is equal to,

Answer:

0.37 feet.

Step-by-step explanation:

The following data were obtained from the question:

Volume (V) = 4100 ft³

Height (h) = 1.8 miles

Radius (r) =?

Next, we shall convert 1.8 miles to foot.

This can be obtained as follow:

Recall:

1 mile = 5280 ft

Therefore,

1.8 miles = 1.8 × 5280 = 9504 ft

Finally, we determine the radius as follow:

Volume (V) = 4100 ft³

Height (h) = 9504 ft

Pi (π) = 3.14

Radius (r) =?

V = πr²h

4100 = 3.14 × r² × 9504

4100 = r² × 29842.56

Divide both side by 29842.56

r² = 4100/29842.56

Take the square root of both side

r = √(4100/29842.56)

r = 0.37 ft

Therefore, the radius of the hole is 0.37 feet.

[tex](-7,4]\text{ or }\{x|-7<x\leq 4\}[/tex]

Step-by-step explanation:

The domain is the span of x-values covered by the function.

From the graph, we can see that the graph covers all the x-values from x=-7 to x=4.

However, note that closed and open circles. There is an open circle at x=-7, which means that the domain excludes x=-7. However, the circle at x=4 is closed, meaning it is included in the domain.

Therefore, the domain is, in interval notation:

We use parentheses on the left because we do not include -7. And we use brackets on the right because we do include the 4.

Answer:

Step-by-step explanation:

A recipe for 1 loaf of bread calls for 2 cups of flour, 12 tablespoons of water and 1 teaspoon of salt.

Therefore, if we add 2 loaves of bread then double of ingredients will be required for the recipe.

In the same way if 4 loaves of bread have been added, 4 times ingredients will be required.

If 3 cups of flour are added then 3 times of other ingredients will be required.

So the table will be,

Number of loaves   Cups of flour   Tablespoons of water    Teaspoons of salt

         1                             2                        12                                1

[tex]A=73.5\text{ cm}^2[/tex]

Step-by-step explanation:

The formula for an area of a triangle is:

[tex]A=\frac{1}{2}bh[/tex]

Where b is the base length and h is the vertical height.

From the triangle, we can see that the base is 21 cm while the vertical height is 7. Thus:

[tex]A=\frac{1}{2}(7)(21)[/tex]

Multiply:

[tex]A=\frac{1}{2}(147)[/tex]

Multiply:

[tex]A=73.5\text{ cm}^2[/tex]

And that's our answer :)

The Area of triangle is 73.5 square cm.

We have from the figure,

Base of triangle = 21 cm

Height of triangle = 7 cm

side of triangle = 15 cm

We know the formula for Area of Triangle

Area of Triangle = 1/2 x base x height

Now, plugging the value of base and height in the formula we get

Area of triangle = 1/2 x  base x height

= 1/2 x 21 x 7

= 147/2

= 73.5 square cm

Answer:

24

Step-by-step explanation

36-12=24

Its as simple as that.

A number plus 12 is 36. The equation for the given calculation is 36 - 12 = 24.

Arithmetic is the fundamental branch of mathematics that covers number operations. Addition, subtraction, multiplication, and division are the operations involved.

The difference between each consecutive term in an arithmetic series is constant. The series 3, 5, 7, 9..., for example, is arithmetic because the difference between consecutive terms is always two.

Because the difference between subsequent words is always negative five, the sequence 21, 16, 11, 6... is also arithmetic.

Let the number added to 12 is x

Then,

12 + x = 36

x = 36 - 12 = 24

Therefore, the equation for the given calculation is 36 - 12 = 24.

Question:

Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the  water. At the end of his jump, Danny was 2.3 meters below the surface of the water.

The following equation describes this situation  14.2 + (-16,5) = -2.3 .

What does -16.5 tell us?

Answer:

The displacement between his current position and his initial position

Step-by-step explanation:

Given

[tex]Initial\ Position = 14.2m[/tex]

[tex]Final\ Position = -2.3m[/tex]

[tex]14.2 + (-16.5) = -2.3[/tex]

Required

What does -16.5 represents?

To understand this, we need to first calculate the displacement between his initial and final position

[tex]Displacement = Final\ Position - Initial\ Position[/tex]

[tex]Displacement = -2.3m - 14.2m[/tex]

[tex]Displacement = - 16.5m[/tex]

So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

Answer:

400 feet

Step-by-step explanation:

We just need to find h when t = 5. To do so, we can plug t = 5 into the function, which would be:

h = -16t² + 120t + 200

  = -16 * 5² + 120 * 5 + 200

  = -400 + 600 + 200 = 400 feet

Answer:

h = 400 feet

Step-by-step explanation:

given t = 5 seconds

h = -16t² + 120t + 200

just substitute t = 5

h = -16(5)² + 120(5) + 200

h = 400 feet
