Answer:
240 should be the answer
Step-by-step explanation:
80% of 300 is 240
Answer:
The correct answer would be 240. If you start at 10 percent which already gives you 30 then continue to go up. Move on by 10 percent until you get to 80 percent which is the amount of televisions that are high definition. Once you count by 10 percent with 30 everyitme you will lead to the answer of 240.
Step-by-step explanation:
Just count by 30’s eight times and you get your answer which I supplied above. I hope this helps.

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.

You bake cookies for a bake sale. The ratio of chocolate chip cookies to oatmeal cookies is 7 : 5. You bake 15 oatmeal cookies. How many chocolate chip cookies do you bake?
Answers
Answer:
21
Step-by-step explanation:
[tex]\frac{7}{5}[/tex] = [tex]\frac{x}{15}[/tex]
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.

To aid in sea navigation, Little Gull Island Lighthouse shines a light from a height of 91 feet above sea level with an unknown angle of depression. If the beam of light shines on the sea surface at a point that is 865 feet away from the base of the lighthouse, what is the angle of depression?
Answers
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]

Prove that sin(3x)/sin(x)·cos(x) = 4cos(x)-sec(x)
Answers
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.
What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.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)}.

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
x ≈ 44.69
