Answer:

C 1099

Step-by-step explanation:

The volume of a cylinder is given by

V = pi * r^2 *h

We know the radius is 5 and the height is 14

Substitute in what we know

V = 3.14 * 5^2 *14

V = 3.14 *25*14

V =1099 in^3

A merchant buys a television for $125 and sells it for $75 more. what is the percent of markup?

guajiro [1.7K]

Since he sold it for $75 more,

% Mark Up = Mark Up/ Cost Price * 100%

% Mark Up = 75 / 125 * 100%

= 0.6 * 100% = 60%

Percent Mark Up = 60%.

Hope this explains it.

Describe the symmetry of the figure. Identify lines of symmetry, if any. Find the angle and the order of any rotational symmetry

Sophie [7]

Answer:

see below

Step-by-step explanation:

Clearly, if you turn the figure sideways or upside down (rotate 90° or 180°), you do not have the same figure. It has no rotational symmetry.

However, if you reverse it left-to-right, you get exactly the same figure. So, it has line symmetry about a vertical center line.

In △JKL, solve for x. a) 17.32 b) 38.16 c) 66.73 d) 74.89

natita [175]

Answer:

c) 66.73

Step-by-step explanation:

We have been given a right triangle. We are asked to find the value of x for our given triangle.

We can see that x is adjacent side for angle 27 degrees and side Kl is opposite side.

We know that tangent relates opposite side of right triangle to its adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

Upon substituting our given values, we will get:

$\text{tan}(27^{\circ})=\frac{34}{x}$

$x=\frac{34}{\text{tan}(27^{\circ})}$

$x=\frac{34}{0.509525449494}$

$x=66.728757\approx 66.73$

Therefore, the value of x is 66.73 for our given triangle and option 'c' is the correct choice.
