24% of 398 what is it

Answer:

The answer is 88%

Step-by-step explanation:

To find a percentage, just divide the top number by the bottom. 22 divided by 25 is 0.88 which means 22 out of 25 is 88%.

Another way to do it is to multiply both 22 and 25 by 4. The denominator will now equal 100 so now the top number will be the percentage. 22*4 is also 88.

Answer:

[tex]\approx 6^\circ[/tex]

Step-by-step explanation:

Given that:

Little Gull Island Lighthouse shines a light from a height of 91 feet above the sea level.

The angle of depression is unknown.

Distance of the point at sea surface from the base of lighthouse is 865 ft.

This situation can be modeled or can be represented as the figure attached in  the answer area.

The situation can be represented by a right angled [tex]\triangle ABC[/tex] in which we are given the base and the height of the triangle.

And we have to find the value of [tex]\angle BAD \ or \ \angle C[/tex] (Because they are the internal vertically opposite angles).

Using tangent ratio:

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tanC = \dfrac{AC}{BC}\\\Rightarrow tanC = \dfrac{91}{865}\\\Rightarrow tanC = 0.105\\\Rightarrow \angle C \approx 6^\circ[/tex]

Therefore, the angle of depression is: [tex]\approx 6^\circ[/tex]

Answer:

x<-3

Step-by-step explanation:

Let's do this step by step:

1) isolate 4x : 4x<-6-6

2) so then we get : 4x<-12

3) isolate x :  x< -12/4

WHICH GETS YOU TO: x<-3

Answer:

4x + 6 < -6 = x < −3

The value of x = -2 or greater

x = 21 chocolate chip cookies.

There are 21 chocolate chip cookies do you bake.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.

Given that;

The ratio of chocolate chip cookies to oatmeal cookies is 7 : 5.

And,  You bake 15 oatmeal cookies.

Now,

Since, The ratio of chocolate chip cookies to oatmeal cookies is 7 : 5.

Hence, The amount of chocolate chips = 7x

And, The amount of oatmeal cookies = 5x

Here, You bake 15 oatmeal cookies.

Hence, We get;

The amount of oatmeal cookies = 5x = 15

So, we get;

⇒ 5x = 15

⇒ x = 3

So, The amount of chocolate chips = 7x

                                                      = 7 × 3

                                                      = 21

Thus, There are 21 chocolate chip cookies do you bake.

Step-by-step explanation:

1900 divided by 100 is 19

1% equals 19

1 times 9 equals 9

19 times 9 equals 171

171 = 9%

171 - 1900 = 1729

Answer:

x ≈ 44.69

Step-by-step explanation:

x² = 30² +21² -2(30)(21)Cos123°

x² = 900 + 411 - 1260cos123°

x² = 1311 - 1260cos123²

~Take square root of both sides

x = √1997.245184111

Answer:

It is irrational, if its not a perfect square. Since 45 is not a perfect square, it is an irrational.

Step-by-step explanation:

Here is a huge hint:

sin(3x) = 3 sin (x) - 4(sin x)^3

sec (x) = 1/sin(x)

Take it from here.

The expression {4 cos(x) - sec(x)} is equivalent to {sin(3x)/sin(x) cos(x)} is proved below.

Given is the equation -

sin(3x)/(sin(x)·cos(x)) = 4cos(x) - sec(x)

We have the following equation -

{sin(3x)/(sin(x)·cos(x)} = 4cos(x) - sec(x)

Now, we know -

sin3x = 3 sin x - 4 sin³x

So, we can write -

(3 sin x - 4 sin³x)/(sin(x)·cos(x) = 4cos(x) - sec(x)

sin(x) (3 - 4sin²x) / sin(x) cos(x) = 4cos(x) - sec(x)

(3 - 4sin²x)/cos(x) = 4cos(x) - sec(x)

(3 - 4sin²x) = cos(x){4 cos(x) - 1/cos(x)}

(3 - 4sin²x) = 4cos²x - 1

3 + 1 = 4cos²x + 4sin²x

4 = 4(cos²x + 4sin²x)

4 = 4

1 = 1

LHS = RHS

Therefore, it is proved that the expression {4 cos(x) - sec(x)} is equivalent to {sin(3x)/sin(x) cos(x)}.
