The teams ratio of games won to games played was 5 to 6 If. The team played 36 games, how many games did the team fail to win
Answer:The team failed to win 6 games.
Step-by-step explanation: 5/6 has to be equal to something over 36. Since you multiplied the denominator by 6 you have to multiply the numerator by 6 and 5*6 equals 30. If out of 36 games they won 30. Then to find how many games they lost all that you have to do is subtract 36 and 30 to get 6.
Ethane (C2H6) is one of many compounds that burns in oxygen to form carbon dioxide and water, as represented by the equation.
2C2H6 + 7O2 → 4CO2 + 6H2O
Which substance is a product in this reaction?
carbon (C)
oxygen (O2)
water (H2O)
ethane (C2H6)
Answer:
Water (H2O)
Step-by-step explanation:
When hydrocarbons undergo combustion reactions (I.e reactions with oxygen) carbon (iv) oxide and water are usually produced.
In this case, the only difference is the numbe of moles between the product and reactant
Equation of reaction;
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Reactants:
1. Ethane = C₂H₆
2. Oxygen = O₂
Product:
1. Carbon(iv) oxide = CO₂
2. Water = H₂O
Answer:
H20

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.

A. unlikely
B. Likely
C. neither Likely or unlikely
Answer:
C. neither Likely or unlikely
Step-by-step explanation:
Its neither because its a 50/50 chance it will land on either side.
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.

Find the value of Y.
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.

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.
1. solve the following quadratic equation by factoring. Show all work and check your answer.
x^2 + 3x – 4 = 0
Answer:
x = -4, x = 1
Step-by-step explanation:
x^2 + 3x - 4 = 0
4 and -1 add to 3 and multiply to -4.
(x+4)(x-1) = 0
Separate these by the Zero Product Property.
x+4 = 0
x-1 = 0
Solve.
x = -4
x = 1
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]

What is the volume of a hemisphere with a diameter of 51.8 inches rounded to the nearest 10th of a cubic inch?
Answer:
volume of a hemisphere ≈ 36369.5 in³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
= [tex]\frac{4}{3}[/tex]πr³ ÷ 2
=[tex]\frac{2}{3}[/tex] πr³
where r is the radius
from the question given, diameter = 51.8 inches
but diameter = 2r , this implies that r = [tex]\frac{d}{2}[/tex] hence r = [tex]\frac{51.8}{2}[/tex] = 25.9 inches
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the formula
volume of a hemisphere =[tex]\frac{2}{3}[/tex] πr³
=[tex]\frac{2}{3}[/tex] × 3.14 ×25.9³
=[tex]\frac{2}{3}[/tex] × 3.14×17373.979
≈36369.5 in³ to the nearest tenth cubic inch.
volume of a hemisphere ≈ 36369.5 in³

36388.0 in3

Answer: Isosceles
Step-by-step explanation:
Given: AB || DE , BC is a transversal
∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°
∠DCA, ∠ACB, & ∠BCA are supplementary --> ∠ACB = 50°
By the Triangle Sum Theorem, ∠A+∠B+∠C = 180° --> ∠CAB = 50°
Triangle is isosceles because ∠A ≅ ∠C
Rosa has 16 pieces of ribbon that she is using for a project.if each ribbon is 5/8 yard long how many yards of ribbon does rosa have?
Answer:
Step-by-step explanation:
Length of each ribbon = 5/8 yards
Length of 16 pieces of ribbon = 16* (5/8)
[tex]=16*\frac{5}{8}\\\\=2 * 5 \\\\=10[/tex]
= 10 yards
What is the length of a?
Step-by-step explanation:
under root 75 yards square - 45 yards square
so the length of a is 60 yd.

Answer:
n =7
Step-by-step explanation:
(n+1) +1 + (n-1) = value first row
3+ (2n-9) +n = value second row
The value has to be the same
Set the equations equal
(n+1) +1 + (n-1) =3+ (2n-9) +n
Combine like terms
2n+1 = 3n-6
Subtract 2n from each side
2n+1-1 -2n = 3n-6-2n
1 = n-6
Add 6 to each side
1+6 = n-6+6
7 = n
Answer:
n =7
