Answer:

If it travels 12.56 ft in one revolution, then the circumference of the tire is 12.56 ft.

Circumference = 2 x π x radius

12.56=2 x 3.14 x radius

radius x 6.28=12.56

Radius= 2 ft

Answer:

  (c)  (4.92, -0.91)

Step-by-step explanation:

The conversion shown in the attached uses the complex number features of the calculator, so the y-coordinate is shown as an imaginary value. Rounded to 2 decimal places the conversion is ...

  (r; θ) ⇔ (x, y)

  (5; 6.1) ⇔ (4.92, -0.91)

__

The correct answer choice can be made without the use of technology. The sum of the magnitudes of the values of x and y must not be less than r, eliminating the first two choices. The angle 6.1 radians is near the angle 6.28 radians (2π), so is almost 360°. It will be a 4th-quadrant angle, so its y-component will be negative (eliminating the last choice).

The only viable choice for polar coordinates of radius 5 and angle 6.1 radians is the third choice: (4.92, -0.91).

__

Additional comment

The angle given has no units, so we assume it is given in radians. A calculator can only give a proper answer if it is set to radians mode for angles.

Answer:

Miranda. Because she earns $10 per hour while Tommy earns $8 per hour.

Step-by-step explanation:

y = 10x <--- 10 is the amount she earns per every x, which is the number of hours she works.

Tommy's equation is y = 8x

Because if you plug in his values of time (x) and total cash earned (y) you get:

32=?4

Read the above ^ as " 32 = blank multiplied by four "

subtract both sides by four to find blank

Our blank equals 8, which is the amount Tommy makes per hour.

By using relation between ml and litre we got that 0.71 ml is equal to 0.00071 L

Relation between ml and litre is that 1 litre =1000 ml

we know that litre and ml are two units of volume and we can convert data from one to another using their relation

Now here given data is in ml

and data is 0.71 ml

We can convert 0.71 ml in litre as

71ml = 0.71/1000 litre

71ml= 0.00071 litre =0.00071 L

By using relation between ml and litre we got that 0.71 ml is equal to 0.00071 L

Answer:

x = 25

Step-by-step explanation:

The sum of the angles in a triangle are equal to 180 degrees. Since we know the value of one angle is 90 degrees, subtract 90 from 180 to get 90. Now we know the sum of the other two angles must equal 90 degrees. If we add the x and 2x + 15 together, we get 3x + 15 = 90. Subtract 15 from both sides to get 3x = 75. Divide both sides by 3 to get x = 25.

Step-by-step explanation:

Formula:

Area of circle = (¶d^2)/4

Given:

d = 34 mm

3.14

Solution:

Area A = (3.14 x 34^2)/4

= 907.46 mm2

[RevyBreeze]

The circumference of the circle is 106.76 km.

Circumference of a circle is defined as the total length of the boundary of the circle.

The concept is same as the perimeter for straight sided figures.

Given that,

The diameter of a circle is 34 kilometers.

Diameter of the circle = 34 kilometers

Radius of the circle = Half of diameter = 34 / 2 = 17 km

Circumference of the circle = 2πr, where r is the radius of the circle.

Circumference = 2π × 17

                         = 34π

                         = 106.76 km

Hence the circumference of the circle is 106.76 km.

The sample size of the actors is the number of actors Darrien selected

The sample size is 15

From the question, we understand that:

Darrien has 60 actors

This represents the population of the experiment.

Then he selected 15 of the actors, and 8 of them have previous acting experience.

The 15 actors he selected represents the sample of the experiment

Hence, the sample size is 15

Answer:

The automobile's average speed is 53.33 mph.

Step-by-step explanation:

Since average speed equals total distance traveled divided by the time of the travel we have:

d = 320 mi the distance traveled

t = 6 hr the time of the travel

v = average speed

v = d/t

v = 320/6

v = 53.33 mph

Answer:

about 53 miles per hour

Step-by-step explanation:

320/6 is 53.33 repeated

you divide 320/6 because you need to know how many miles you going in an hour
