Answer:

r = 6.998 in

D = 13.996 in

C = 43.9697 in

Step-by-step explanation:

Area = π\(r^2\)

153.86 = π\(r^2\)

153.86/π = \(r^2\)

sq root(153.86/π) = r ≈ 6.998 in

Diameter = 2r

D = 2(6.998) = 13.996 in

Circumference = 2πr

C = 2π(6.998)

C = 13.996π ≈ 43.9697 in

Answer:

v > -1

Step-by-step explanation:

v + 6 > 5

We want to work backwards to solve this, therefore we must subtract 6 on both sides to isolate v.

v + 6 > 5

  (- 6)  (-6)

v > -1

First, we need to know the different trigonometric identities.

These trigonometric identities are expressed as;

From the information given, we have that;

Angle of depression = 2 degrees

The hypotenuse side = 6 miles

Using the cosine identity, we have;

cos θ = adjacent/hypotenuse

substitute the values, we have;

cos 20 = h/6

cross multiply the values, we get;

h = 6 × 0. 93

Answer:

1 5/36

Step-by-step explanation:

need a common denominator which would be 36

to get from 9 to 36 you multiply by 4 so 5 would be multiplied by 4 to get the fraction 20/36

do the same with 7/12 12x3 is 36 and 7x3 is 21 so 21/36

then add 20+21=41

put over 36       41/36

Find if you can lower it which you can:

41 is bigger than 36 by 5 so your ending fraction would be 1 and 5/36 because 5 and 36 don't have a common factor.

The area of the equilateral triangle with a side length of 8 cm is 16√(3) cm².

To find the altitude of an equilateral triangle with a side length of 8 cm, we can use the Pythagorean theorem.

The Pythagorean theorem is states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

In these triangles, the side opposite the 60-degree angle is half the length of the hypotenuse, which is 8 cm. Using the Pythagorean theorem, we can find that the length of the altitude is:

Altitude = √(8² - (4²)) = √(48) = 4√(3)

Now that we know the altitude, we can plug it into the formula for the area of a triangle:

Area = (base x height) / 2 = (8 x 4√(3)) / 2 = 16√(3) cm²

Answer:

241.5cm³

Step-by-step explanation:

Volume of the glass = Volume of the cuboid - Volume of the cylinder

Volume of the cuboid = Length * width * height

Volume of the cuboid  =  8cm * 4cm * 10cm

Volume of the cuboid  = 320cm³

Volume of the cylinder = πr²h

Radius r = 5/2 = 2.5cm

height = 4cm

Volume of the cylinder = 3.14(2.5)²*4

Volume of the cylinder = 78.5cm^3

Volume of the glass = 320 - 78.5

Volume of the glass = 241.5cm³

Answer:

5.25 hours

Step-by-step explanation:

So in a week there is 7 days and we know she reads EACH night 0.75  so we know we have to multiply:

0.75 x 7= 5.25

So In one week or 7 days she read 5.25 hours.

To represent the logic function that takes the value '1' if and only if there are no adjacent empty chairs, we can use four input variables, each representing the occupancy of a chair. Let's call these variables A, B, C, and D, corresponding to the chairs from left to right. The logic function can be defined as follows:

F = (A + B)(B + C)(C + D)

This function is in the Sum of Products (SoP) form and represents the logical conjunction (AND) of three conditions: (1) A and B are occupied, (2) B and C are occupied, and (3) C and D are occupied. If all these conditions are true, it implies that there are no adjacent empty chairs, and hence, the function evaluates to '1'. To realize this logic function using an 8x1 multiplexer and other logic gates, we can assign the input variables A, B, C, and D to the select inputs of the multiplexer.

The data inputs of the multiplexer can be connected to the constant value '1'. The output of the multiplexer will be the value of the function F, which will be '1' if and only if there are no adjacent empty chairs. Additional logic gates may be required to manipulate the inputs and outputs as needed to achieve the desired functionality.

Speed of tip of the shadow of woman  = 6 ft/s

What are similar triangles?

Two triangles are said to be similar, if the corrosponding angles of the triangles are same and the corrosponding sides of the triangles are in the same ratio.

Here,

The diagram has been attached here

Let the distance of woman from the pole be x ft and the distance of tip of the shadow to the pole be y ft.

Height of street light = 18 ft

Height of woman = 6ft

The two triangles are similar [As height of woman is parallel to the height of pole]

\(\frac{y - x}{6}=\frac{y}{18}\\18y - 18x = 6y\\18y - 6y = 18x\\12y = 18x\\y = \frac{18}{12}x\\y = \frac{3}{2}x\\\)

To find the speed, we have to differentiate both sides with respect to time 't'

\(\frac{dy}{dt} =\frac{3}{2}\frac{dx}{dt}\\\frac{dy}{dt}=\frac{3}{2} \times 4\\\frac{dy}{dt} = 6\)

Speed of tip of her shadow = 6 ft

By dividing the angle of rotation by the duration of one rotation, the angular velocity of the Earth around its axis can be determined. The time it takes the Earth to complete one full rotation, which is equivalent to 360 degrees or 2 radians, is roughly 24 hours.

Angle change divided by time change equals angular velocity (v), as follows:

ω = θ / t

We can substitute the following values into the equation since the Earth completes one rotation every 24 hours:2 radians each day equals.

By multiplying by 3600 (the amount of seconds in an hour), we may convert the time from hours to seconds:

2 radians are equal to (24 hours * 3600 seconds/hour)

Answer: 12mm

Step-by-step explanation:

Basically, you will find the circumference of the entire circle and then using that find the length of the arc.

So the circumference of the circle is its radius (11) times pi multiplied by 2.

2(11 x 3.14) = 69.08

Now a circle is always 360 degrees and the angle of the sector is 60 degrees.

So we have our circumference and we only need that small portion, so you take and make it a fraction and multiply by the circumference to find the length of that small portion:

60/360 x 69.08 = 11.51

Rounded = 12
