Two years ago there were 20 trailer homes on Elm Street with an average age of 18 years. At that time, a group of brand new trailer homes was then added to Elm Street. Today, the average age of all the trailer homes on Elm Street is 14 years. How many new trailer homes were added two years ago?
Answers
Answer:
The number of new trailer homes that were added two years ago is 10
Step-by-step explanation:
Given that
Twenty years ago there are 20 trailer homes having an average age of 18 years
Today, the average of the age is 14 years
We need to find out the number of new trailer homes that would be added two years ago
Since as of now 20 trailer homes would be an average of 20 years and we assume the new trailers be n that are 2 years old
So
20 + n
And, the sum of their ages i.e. (20) ( 20) + 2n
Now the following equation is used
[tex]\frac{400 + 2n}{20 + n} = 14[/tex]
400 + 2n = 14(20 + n)
400 + 2n = 280 + 14n
120 = 12n
n = 10
Hence, the number of new trailer homes that were added two years ago is 10

If a || b || c and m∠9 = 76°, find the measure of each missing angle.
Answers
Answer:
m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°
m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 104°
Step-by-step explanation:
Vertical angles are congruent. When lines are parallel, corresponding angles are congruent.
m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°
m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 180 - 76° = 104°

Step-by-step explanation:
Sorry if the explanation is messy
answer
x=29.44
y=48.08
z=68
Step-by-step explanation:
opp/adj = tan(30)
17/x = tan(30)
x = 29.44
hyp^2 = x^2+y^2
hyp^2 = (29.44)^2 + (17)^2
hyp^2 = 867 + 289
hyp = 34
opp/hyp = Sin(45)
34/y = Sin(45)
y = 48.08
adj/hyp = Cos(45)
z/(48.08) = Cos(45)
z = 68

Chapter 1
At A Nation's Crisis
The Pony Express was the first rapid transit and the first fost mail line across the continent from the Missouri River to the Pacific Coast. It was a system
by means of which messages were carried swiftly on horseback across the plains and deserts, and over the mountains of the far West It brought the
Adontic coost and the Pacific slope ten days nearer to each other.
It had a brief existence of only sixteen months and was supplanted by the transcontinental telegraph. Yet it was of the greatest importance in
binding the East and West together at a time when overland travel was slow and cumbersome, and when a great national crisis made the rapid
communication of news between these sections an imperative necessity.
The Pony Express marked the highest development in overland travel prior to the coming of the Pacific railroad, which it preceded nine years.
It, in fact, proved the feasibility of a transcontinental road and demonstrated that such a line could be built and operated continuously the year
around-a feat that had always been regarded as impossible.
The operation of the Pony Express was a supreme achievement of physical endurance on the part of man and his ever faithful companion, the
horse. The history of this organization should be a lasting monument to the physical sacrifice of man and beast in an effort to accomplish
something worthwhile. Its history should be an enduring tribute to American courage and American organizing genius.

height of 256 feet. Four

Write an equation to
model the scenario.
Answers
Answer:
Step-by-step explanation:
2.256 = 4x
So first Maya throws the rock from the 192-foot cliff into the ocean.
After 2 seconds, the rock reaches a maximum height of 256 feet;
so 2 seconds, 256 feet - 2.256After 4 seconds, the rock reaches the ocean.
so 4 seconds, it reaches the ocean but we don't know how many feet. ( x )-- 4 seconds, x feet.equation: 2 . 256 = 4 . xGood luck!
The required equation that represents the scenario is x = 64 * 2 + 256 * 4
Given that,
Maya throws a rock straight up from the edge of a 192-foot cliff and into the ocean. After two seconds, the rock reaches a maximum height of 256 feet. Four seconds later, the rock enters the ocean. To write an equation to model the scenario.
the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
let the total distance covered by the rock vertically be x,
now,
Distance traveled by the rock vertical upward in 2 seconds = 2 * (256 - 192)
= 2 * 64
Distance traveled by the rock vertical downward in 4 seconds = 4 * 256
Total distance,
x = 2 * 64 + 4 * 256
Thus, the required equation that represents the scenario is x = 64 * 2 + 256 * 40.

b. JK = 799
C.
JK = 140.5°
JK = 50.5°
d.
Answers
Answer:
a) 101°
Step-by-step explanation:
arc HK = 2(39.59°) = 79.18°
arc JH = 180°
arc JK = 360° - 180° - 79.18° = 100.82°
JK = 101°
The correct answer is option (A) 101°
What is an inscribed angle?"It is an angle in a circle formed by two chords that have a common end point on the circle."
For given example,
m ∠J = 39.59°
We know, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.
⇒ m(∠J) = (1/2) × arc KH
⇒ arc KH = 2 × 39.59°
⇒ arc KH = 79.18°
Also, arc HJ = 180°
We know for given figure,
⇒ arc JK + arc KH +arc HJ = 360°
⇒ arc JK + 79.18° + 180° = 360°
⇒ arc JK + 259.18° = 360°
⇒ arc JK = 100.82°
⇒ mJK ≈ 101°
Therefore, mJK = 101°
The correct answer is option (A) 101°

I want to build a shed that is 16‘ x 20‘ while I am measuring the foundation I measure the diagonal from one born to another measurement is 29 feet is the corner 90°?
Answers
Answer:
the corner is not 90 degrees
Step-by-step explanation:
To confirm if the corner is 90 degrees, we would use Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
16² + 20² =
256 + 400 =656
find the square root of 656
= 25.6 feet
If the corner was 90 degrees the diagonal should be 25.6 feet and not 29 feet
Una muestra de 800 gramos de avellana con cáscara tiene 500 gramos de grano. ¿cuántosgramos de grano habrá en 2,4 kg de avellana con cáscara?
Answers
Answer:
1500 grams of grain
Step-by-step explanation:
How many grams of grain will there be in 2.4 kg of shelled hazelnuts?
Step 1
Convert kg to g
1 kg = 1000g
2.4 g = x
Cross Multiply
x = 2.4 × 1000g = 2400g
Step 2
An 800 gram sample of shelled hazelnuts has 500 grams of grain.
Hence,
800g hazelnuts = 500 gram of grain
2400g hazelnuts = x
Cross Multiply
800x = 2400g × 500g
x = 2400g × 500g/800
x = 1500 grams of grain
