.24 or 24% people will say they did not like the movie, because if 99/130 liked it, that means 31/130 day they do not like it, and that simplified into a decimal is .24, which also equals 24%

What is the cosine of angle P?
never [62]
The cosine of an angle is defined as the sine of the complementary angle. The complementary angle equals the given angle subtracted from a right angle, 90°. For instance, if the angle is 30°, then its complement is 60°. Generally, for any angle θ, cos θ = sin (90° – θ).

What is the distance between (9,-4) and (-22, 8)?
MariettaO [177]

Answer:

≈ 33.2 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (9, - 4) and (x₂, y₂ ) = (- 22, 8)

d = \sqrt{(-22-9)^2+(8+4)^2}

   = \sqrt{(-31)^2+12^2}

   = \sqrt{961+144}

    = \sqrt{1105} ≈ 33.2 ( to 1 dec. place )

A cyclist rides her bike at a rate of 8 miles per hour. What is this rate in kilometers per hour? How many kilometers will the c
alina1380 [7]
1 mile is equal to 1.6 kilometers, so 8 miles (using a direct proportion) should be equal to 8 * 1.6 = 12.8 kilometers. The cyclist rides at 12.8 kilometers per hour. In four hours, the cyclist would have rode 12.8 * 4 = 48 + 3.2 = 51.2 kilometers.

Determine the equation of a line in standard form that represents alanas training progress. Her progress points corresponds to t
elixir [45]

Answer:

The equation of the line passing through the above points is:

y=-\frac{1}{2}x+\frac{29}{2}

Step-by-step explanation:

Given:

The two points are: (x_1,y_1)=(1,14)\textrm{ and }(x_2,y_2)=(9,10)

The equation of a line when two points are given is:

y-y_1=\left (\frac{y_2-y_1}{x_2-x_1} \right )(x-x_1)

Plug in all the values and simplify.

y-14=\left (\frac{10-14}{9-1} \right )(x-1)\\y-14=\left (\frac{-4}{8} \right )(x-1)\\y-14=-\frac{1}{2}(x-1)\\y-14=-\frac{1}{2}x+\frac{1}{2}\\y=-\frac{1}{2}x+\frac{1}{2}+14\\\\\\y=-\frac{1}{2}x+\frac{29}{2}

Therefore, the equation of the line passing through the above points is:

y=-\frac{1}{2}x+\frac{29}{2}
