A standard television has a width-to-height aspect ratio of 4:3. How many cm is the
diagonal of a standard television screen that is 49.8 cm tall?
Answer:
Diagonal of television = 83 cm
Step-by-step explanation:
Width of television = 4x
height of television = 3x
Height of television = 49.8 cm
[tex] \therefore \: 3x = 49.8 \\ x = \frac{49.8}{3} \\ x = 16.6 \: cm \\ 4x = 4 \times 16.6 = 66.4 \: cm \\ \\ diagonal \: of \: television \\ = \sqrt{ {(66.4)}^{2} + (49.8)^{2} } \\ = \sqrt{ 4,408.96 + 2,480.04 } \\ = \sqrt{6,889} \\ = 83 \: cm \\ [/tex]

Step-by-step explanation:
last month maria purchased a new cell phone for $500. the store manager told her that her cell phone would depreciate by 70% every 6 months. maria thinks she will want to replace her phone after a while. what will be the value (V) of her phone if she tries to trade it in after 2 years? select ALL that apply.
A: V=500(0.70)⁴
B: V=500(0.30)⁴
C: V=500(0.30)²
D: V=500(1 - 0.70)⁴
E: V=0.70(500)⁴
F: V=0.30(500)²
We have been given that last month Maria purchased a new cell phone for $500. The store manager told her that her cell phone would depreciate by 70% every 6 months.
We know that an exponential function is in form [tex]y=a\cdot (1-r)^x[/tex], where,
y = Final value,
a = Initial value,
r = Decay rate in decimal form,
x = Time in years.
Let us convert [tex]70\%[/tex] into decimal form.
[tex]70\%=\frac{70}{100}=0.70[/tex]
Initial value of car is 500, so [tex]a=500[/tex].
Since value of phone depreciates every months, so value of phone will depreciate twice in a year.
Upon substituting our given values in exponential decay function, we will get:
[tex]V=500(1-0.70)^{2x}[/tex]
To find the value of phone after 2 years, we will substitute [tex]x=2[/tex] in our equation.
[tex]V=500(1-0.70)^{2(\cdot 2)}[/tex]
[tex]V=500(1-0.70)^{4}[/tex]
Therefore, option D is the correct choice.
Let us simplify our equation.
[tex]V=500(0.30)^{4}[/tex]
Therefore, option B is correct as well.

Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle? The triangle is a right triangle because 52 + 122 = 132. The triangle is a right triangle because 5 + 13 > 12. The triangle is not a right triangle because 52 + 132 > 122. The triangle is not a right triangle because 5 + 12 > 13.
Answer:
The Triangle Is A Right Triangle Because 5^2 + 12^2 = 13^2.
Step-by-step explanation:
5^2 = 25. 12^2 = 144. With the Pythagorean theorem, (a^2 + b^2 = c^2), 5 is a, 12 is b, and 13 is c.
25 + 144 = 169.
13 ^ 2 = 169.
Since a^2 + b^2 = c^2 is true, the triangle is a right triangle.
Given:
Sides of triangle= 5cm, 13cm and 12cm
To find: Whether a triangle is a right angled triangle.
This can be solved by applying Pythagorean theorem:
According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
[tex]H^2=P^2+B^2[/tex]
where,
H= Hypotenuse
P= Perpendicular
B=Base
Applying given values in the formula:
[tex]H^2=P^2+B^2\\\\13^2=5^2+12^2\\\\169=25+144\\\\169=169[/tex]
Since, R.H.S= L.H.S
Thus, we can say that this triangle is a right angled triangle.

Please do not answer unless you know the answer
Answer:
66
Step-by-step explanation:
Answer:
y=66
Step-by-step explanation:
Start with the angle that has the purple arrow pointing to it. Next to it, part of the right angle is 27 degrees so you subtract that from 90 degrees, which makes you get 63 degrees. The measurement of all a triangle's angles is 180 degrees, so you add 63 and 51 to get 114, then subtract 114 from 180 to get 66 degrees.

Which system of inequalities is shown?
The system of inequalities is y<x and y<4.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other.
To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given, the region is shaded y < 4.
And the region is not exceeding the x.
So, y<x.
Therefore, the system of inequalities is y<x and y<4.

(5x)"
R

(25x + 30)
0 25°
w

s
Answer:
WRS=25 degree
Step-by-step explanation:
Angle VRT + angle TRS = 180 degree (supplementary angles)
5x+25x+30=180
5x+25x=180-30
30x=150
x=150/30=5
Substituting x=5 into angle VRT
5(5)=25
VRT= 25 degree
Looking at the diagram, angle VRT and angle WRS are vertically opposite angle and are therefore equal.
Now, angle WRS= 25 degree
The measure of the angle of intersecting lines ∠WRS = 25°
What are the angles formed by 2 intersecting lines?Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Given data ,
Let the two intersecting lines be a and b
where the measure of ∠SRT = ( 25x + 30 )°
The measure of angle ∠VRT = ( 5x )°
And , the measure of ∠VRT = measure of ∠WRS ( Opposite angles are congruent )
And , the measure of ∠VRT + measure of ∠SRT = 180° ( angles in straight line )
So , 5x + 25x + 30 = 180
30x = 150°
Divide by 30 on both sides , we get
x = 5
Now , the measure of ∠WRS = [ 5 ( 5 ) ] °
Hence , the measure of angle ∠WRS = 25°

Explain the concept of regression to the mean between
generations.
Answer:
Regression to the mean occurs when the next generation regresses to the overall mean of the population.
Step-by-step explanation:
Regression to the mean occurs when the next generation regresses to the overall mean of the population. Extreme traits trend back to the average and are not increased or decreased in terms of measure. Measurable traits or characteristics that are extreme move back toward the average value. The next generation traits move back, or regress, to the average of that trait
Answer:
Regression to the mean is a statistical phenomenon that occurs whenever you have a nonrandom sample from a population and two measures that are imperfectly correlated.
Step-by-step explanation:
