on a scale of one to 100, your teacher crankiness is directly proportional to the number of students talking while she is talking, the teachers crankiness index is 5. What is her crankiness index when 6 students are talking?

Answer:

56

Step-by-step explanation:

Simplifying

x + 7x = 56 + 8

Combine like terms: x + 7x = 8x

8x = 56 + 8

Combine like terms: 56 + 8 = 64

8x = 64

Solving

8x = 64

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '8'.

x = 8

Simplifying

x = 8

Answer:

.8

Step-by-step explanation:

14/17 as a decimal is 0.82352941176

we only need to know what its the hundredths and tenths place so we then just round to thenearest tenth so 2 is less than 5 so 8 stays the same therefor out answer is .8

The closest to sea level is - 11. The minus sign indicates that you are below 0 or the level of the sea at that location. So what is true and what isn't?

Grasshopper meadow is not closest to sea level. At 15 feet it is 4 feet more above the closest one at - 11. False

Echo point is the highest above sea level. It is 45 feet above sea level. This statement is also False.

Answer:

? ≈ 25.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan? = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{14}{29}[/tex] , then

? = [tex]tan^{-1}[/tex] ( [tex]\frac{14}{29}[/tex] ) ≈ 25.8° ( to 1 dec. place )

Answer:

Speed of the car is 40 km/h

Speed of the motorcycle is 60 km/h

Answer:

r = 6

Step-by-step explanation:

The value of radius of the sphere rounded to the nearest whole number is,

⇒ r = 6 cm

We have to given that,

Volume of a sphere = 905 cm

Since, We know that,

Volume of sphere = 4/3 (πr³)

Where, 'r' is radius of sphere.

Now, Substitute the given value, we get;

⇒ 905 = 4/3 (πr³)

⇒ 905 × 3 = 4 × 3.14 × r³

⇒ 2,715 = 12.56 × r³

⇒ r³ = 216.16

⇒ r = ∛216.16

⇒ r = 6 cm

Thus, The value of radius of the sphere rounded to the nearest whole number is,

⇒ r = 6 cm

Answer:

A and D are correct!

Step-by-step explanation:

The origin is 0,0

The x axis is the one that R is on right now

The correct statements are,

A) The point is 3 units right to the origin.

D) The x coordinate is 3.

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

The point R is shown in graph.

Nom,

Since, The point R is shown in graph.

Clearly, The coordinate of R = (3, 0)

So, We have;

⇒ The point R is 3 units right to the origin.

And, The x coordinate is 3.

Step-by-step explanation:

Opposite = 30 feet and the length of the wire (I'll use x to represent it) is the hypotenuse.

sin(48) = 30/x

x = 30/sin(48)

x = 30/0.74
