Un hotel tiene 120 habitaciones, entre dobles i individuales. Si la cuantidad de camas son de 195, cuantas habitaciones dobles hay? Y individuales?
Answer:
45 individuales y 75 dobles.
Step-by-step explanation:
Para saber esto, debemos plantearlo por medio de un sistema de ecuaciones. En este caso las incógnitas serían el tipo de habitación, es decir, una será la habitación doble, y la otra la individual.
X: habitaciones individuales
Y: habitaciones dobles
Sabiendo eso, sabemos que sumando ambos tipos de habitaciones, dan el total de 120, por tanto, la primera ecuación será:
x + y = 120 (1)
Para la segunda ecuación, sabemos que hay 195 camas en total, que deben distribuirse en los dos tipos de habitaciones, en una habitación doble van 2 camas, mientras que en una individual va 1, por tanto:
x + 2y = 195 (2)
Ahora que tenemos las dos ecuaciones, solo resta resolverlo por alguno de los métodos conocidos de sistema de ecuaciones. En este caso, como las ecuaciones son sencillas podemos usar el método de reducción.

1a.) Brian borrowed 4 non-fiction books from the library. This was 25% of the
books he checked out. How many books did Brian check out? *
Answer:
Total number of books borrowed= 16
Step-by-step explanation:
Giving the following information:
Number of non-fictions books= 4
Percentage of books borrowed= 25% = 0.25
To calculate the total number of books borrowed, we need to use the following formula:
Total number of books borrowed= 4 / 0.25
Total number of books borrowed= 16
What is the y-intercept of the line?
Answer:
3
Step-by-step explanation:
How I found it?
Look at the middle of the line where is the line at, thats ohw you find the y-interccept.
3
Solution:The y-intercept is the point where the graph intersects the y-axis.Usually the y-intercept is written as(0, b) where "b" represents the y-intercept.The given graph intersects the y-axis at (0, 3)Therefore, the y-intercept is equal to (0, 3) or 3.Hope it helps.

Answer:
cinco = 5
tres = 3
nueve = 9
seis = 6
dos = 2
cuatro = 4
siete = 7
dos = 2
ocho = 9
uno = 2
diez = 10
Step-by-step explanation:
5 is an odd number between 3 and 7
3 × (5-4) = 3
14-5 = 9
6 × 6 = 36
2 × 2 = 4
3 + 4 = 7
2 × 4 = 8

In the spring, the owner of a sporting goods store decreases the price of winter gloves from $10.00 to $8.00. She increases the price of swimming goggles from $8.00 to $10.00.
Without doing the math, do you think that the percent decrease in the price of the gloves is the same as the percent increase of the goggles? Explain your reasoning.
Answer in complete sentences.
Answer:
without doing the math, we can affirm that the percent in decrease in the price of the gloves is not the same as the percent increase of the goggles. decreasing $2 from $10 will have a lower decrease than an increase of $2 from $8 since $2 represents a higher portion of $8 compared to $10

Need help asap, it's asking me to find m angle J and that K = 25.
Answer:
j would be 130 cuz sides that are congruent have congruent angles so you add those two angles up and subtract from 180
Answer:
Step-by-step explanation:
x = 130
Base angles of isosceles triangles are congruent so angle L is also 25
There is 180 degrees in a triangle so you would do 25 + 25 + x = 180
then solve for x

Graph the line . djdjej
Answer:
Step-by-step explanation:
The slope is 2 and the point (0,8) is on the graph. This means we have to plug this equation to y-y1=m(x-x1) where m is the slope. We know the slope and the we have the points (0,8) so we can completely fill in this equation. y-8=2(x-0) is equal to y-8=2x. You want to isolate y so you have to add 8 to both sides. y=2x+8. The graph y=2x+8 will look like this.

The height, h, in feet of a golf ball above the ground after being hit into the air is given by the equation, h = -16t 2 + 64t, where t is the number of seconds elapsed since the ball was hit. How many seconds does it take for the golf ball to hit the ground?
It will take ___seconds for the ball to hit the ground.
Answer:
4 seconds
Step-by-step explanation:
When the ball hits the ground the height is 0
-16t² + 64t = 0
Divide both sides by -16
t² - 4t = 0
Factor out t
t(t - 4) = 0
From the zero product rule
t = 0 and t - 4 = 0
t = {0, 4}
The ball hits the gound after 4 seconds

A rectangular football field is 64 meters wide and 100 meters long. A player runs from one corner of the field in a diagonal line to the opposite corner. How far did the player run? Round to the nearest whole meter. *115 meters
118 meters
119 meters
120 meters
Answer:
119meters
Step-by-step explanation:
We should use the Pythagorean Theorem to solve this problem.
a^2+ b^2=c^2
64^2+100^2=c^2
4096+10000=14096
c^2=14096
c=\sqrt{14096}
14096
And the root of 14096 is 118.726577.
So the Answer is About 119 meters, or 118.726577
Answer:
Solution given:
length[l]/base[b]=100m
wide [w]/perpendicular [p]=64m
distance of diagonal =hypotenuse [h]=?
By using Pythagoras law
h²=p²+b²
h²=64²+100²
h=√14096
h=118.72
=119m approx
So
the player run 119m.

Joe's friends are going to climb a climbing wall and have invited Joe to go with them. Joe is afraid of heights and wants to know how high the climbing wall is before he climbs it. Joe is 5.5 ft tall and at 3:00 pm his shad is 2.75 ft long. At the same time, the shadow of the rock-wall is 35 ft long. How tall is the rock wall?
Answer:
Rock Wall Height = 70ft
Step-by-step explanation:
Joe's height = 5.5 ft , Joe's shadow height = 2.75 ft [At 3.30 pm]
At 3.30 pm , Joe's height : Shadow Radio = 5.5 : 2.75 = 2 : 1
So, Product real height : Shadow height = 2 : 1 [At 3.30 pm]
Rock wall shadow height = 35 ft long
As per Height : Shadow ratio = 2 : 1 . So, rock wall real height = 2 x shadow height = 2 x 35 = 70 ft long
