Answer:

n = 24

Explanation:

The initial expression is:

n + 7 = 31

So, to solve the equation, we need to subtract 7 from both sides:

n + 7 - 7 = 31 - 7

n = 24

Therefore, the solution is n = 24

grigory [225]

We’ll first find how much she has left as her savings
$490-$396.90= $93.70

Now we’ll go for cross multiplication
100% $490
? $93.70

? = 100 x 93.7/490
? = 19.1 %

So the answer is 19.1% which rounded to the nearest whole number is 19%. The answer is the first option.
Hope it helped you

A cone is formed from a 300-degree sector of a circle of radius 18 by aligning the two straight sides. what is the result when t

vampirchik [111]

The radius of the completed cone is

... 18×(300°/360°) = 15

The height of the completed cone is found from the Pythagorean theorem:

... 15² + h² = 18²

... h = √99 = 3√11

The volume is given by

... V = (1/3)πr²·h = (1/3)π·15²·3√11

Dividing this value by π gives 225√11 cubic units.

Answer: the distance of the boat from the foot of the lighthouse is 290.5 feet.

Step-by-step explanation:

The right angle triangle ABC representing the scenario is shown in the attached photo.

Angle A is alternate to the angle of depression, hence, they are the same.

The height of the lighthouse represents the opposite side of the right angle triangle. The distance, x of the boat from the foot of the lighthouse represents the adjacent side of the right angle triangle.

To determine x, we would apply

the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan 11.1 = 57/x

x = 57/Tan 11.1 = 57/0.1962

x = 290.5 feet to the nearest tenth.
