Un químico agrega cierta cantidad de una solución de 86% de alcohol a 11 litros de otra solución al 71% de alcohol y obtiene una solución al 77% de alcohol encuentre la cantidad de litros de la primera solución que se agregaron a la segunda
Answer:
Step-by-step explanation:
Sea x la cantidad de litros de la mezcla al 86%
x× 86% + 11 × 71% = (x + 11) × 77%
0.86x + 7.81 = 0.77x + 8.47

Jake walked all the way around the perimeter of a square playground that has sides n feet long, then he walked an additional 20 feet. Which person walked the same distance as Jake?
Options :
Sarah, who walked a straight distance of n+10 feet.
Nancy, who walked around a square garden measuring n+5 feet on each side.
Jules, who walked around a rectangular room measuring n feet wide and 10 feet long.
Billy, who walked around a square lot measuring 20 feet on each side
Answer:
Nancy, who walked around a square garden measuring n+5 feet on each side.
Step-by-step explanation:
Given that:
Jake walked round the perimeter of a square with sides n feets long
Additional distance walked = 20 feets
Perimeter of a square = 4n
Where n = Length of the side
Hence Jake's total distance :
Perimeter walked + additional distance
4n + 20 feets
Comparing to Distance walked by Nancy:
Side length of square garden = n+5
Perimeter of the garden = 4 * side length
Perimeter of the garden = 4 * (n + 5)
Perimeter of the garden = 4n + 20 feets
Hence, Nancy walked the same distance as Jake

Write the equation of the line that goes through the point (2, -1) and has a slope of
-3.
Answer:
y=-3 -1
Step-by-step explanation:
y=mx+b m=slope b= y intercept
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - 3x + 5 ← equation of line

Step-by-step explanation:
Answer:
13/7 or 16/7, they are the same, just different ways of writing it.
Step-by-step explanation:
(6 1/2) / (3 1/2)
Convert to an improper fraction
(13/2) / (7/2)
To divide a fraction, find the reciprocal of the second fraction, and multiply it by the first:
(13/2) * (2/7)

In a survey of 1,500 people who owned a certain type of car, 300 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
20%Step-by-step explanation:
Step one:
total number of people surveyed= 1500
we are told that 300 people would buy that car again,
this implies that they like the car and are satisfied with it
Step two:
the percent of people satisfied can be computed as
=300/1500*100
=3/15*100
=1/5*100
=0.2*100
=20%
The people surveyed were satisfied with the car are 20%

Answer:
y = 3/2x + 2
Step-by-step explanation:
let eqn be y = mx + c
m = (5-2)/(2-0) = 3/2
sub (0, 2):
2 = 3/2 (0) + c
c = 2
therefore, the equation is y = 3/2x + 2

For an activity in class, student used pieces of string to measure road on a map. They used a map scale to determine the distance between two cities. One group measured the distance between Fort Myers and Miami on a Florida state map. The string distance was 7.75 inches, which represents a real-life distance of about 155 miles. Another group measured the distance between Tampa and Orlando on the same map and found that distance to be 4.25 inches. What is the real-life distance to the nearest mile between Tampa and Orlando

A select soccer team had tryouts for the upcoming season. The team typically has 25% of the players in the tryouts process come back for a second evaluation. If the team asked 17 players back for a second evaluation, how many players showed up for the first tryout
Given:
The team typically has 25% of the players in the tryouts process come back for a second evaluation.
The team asked 17 players back for a second evaluation.
To find:
The players showed up for the first tryout.
Solution:
Let x be the number of players showed up for the first tryout.
According to the question,
[tex]25\%\text{ of } x=17[/tex]
[tex]\dfrac{25}{100}x=17[/tex]
[tex]\dfrac{1}{4}x=17[/tex]
Multiply both sides by 4.
[tex]x=17\times 4[/tex]
[tex]x=68[/tex]
Therefore, 68 layers showed up for the first tryout.
Answer:
68

The value of x and y in the given figure is 14° and 23° respectively.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know vertically opposite angles are equal, and we also know that sum of all the interior angles of a triangle is equal to 180°.
∴ 47° + (2x + 13)° + (5y - 23)° = 180°.
47° + 13° - 23° + 2x + 5y = 180°.
2x + 5y = 143°...(i).
Now, We also know that when parallel lines are intersected by a transversal pair of alternate angles are equal and the sum of two adjacent angles is equal to 180°.
∴ 3x + (5y - 23)° = 180°.
3x + 5y = 157°...(ii)
Now subtracting eqn(i) from eqn(ii) we get x = 14°, and substituting the value of x in any of the equations we y = 23°.

Tell me a fun fact about horses will give BRAINLIEST to whoever tells me something I don’t know (I have been riding for 12 years) so I know a lot of things (also don’t tell me they can sleep standing up I already know that it’s kinda obvious)
Here are a few fun facts:
A 19th century horse named 'Old Billy' is said to have lived 62 years.
Horses can sleep both lying down and standing up.
Horses can run shortly after birth.
Horses have around 205 bones in their skeleton.
Horses have been domesticated for over 5000 years.
Horses use their ears, eyes and nostrils to express their mood.
Because horse’s eyes are on the side of their head they are capable of seeing nearly 360 degrees at one time.
The fastest recorded sprinting speed of a horse was 88 kph (55 mph). Most gallop at around 44 kph or 27 mph.
The Przewalski’s horse is the only truly wild horse species still in existence. The only wild population is in Mongolia. There are however numerous populations across the world of feral horses e.g. mustangs in North America.
