Answer: El otro avión recorrió a distancia de 1362.5 km.
Step-by-step explanation:
Vamos a definir:
Norte es el eje y-positivo.
Oriente (o este) es el eje x-positivo.
Y también sabemos que si tenemos los puntos (a, b) y (c, d)
La distancia entre esos puntos es:
Distancia = √( (a - c)^2 + (b - d)^2)
Ahora, uno de los aviones va hacia el norte, entonces si el aeropuerto está en la posición (0, 0), después de un rato viajando hacia el norte su nueva posición va a ser (0, A)
Mientras que el que va al oeste va a tener una nueva posición (B, 0)
La distancia entre ellos es:
Distancia = √( (B - 0)^2 + (0 - A)^2) = √( B^2 + A^2)
Sabemos que cuando la distancia entre ellos es 1580 km, uno de ellos ha recorrido 800km, asumamos que A = 800km.
Entonces tenemos la ecuación:
1580 km = √( B^2 + (800km)^2)
(1580km)^2 = B^2 + (800km)^2
(1580km)^2 - (800km)^2 = B^2
√((1580km)^2 - (800km)^2 ) = B = 1362.5 km
El otro avión recorrió a distancia de 1362.5 km.

What is the slope of the line that passes through the points (-4,5) and (0, -5)? Choose the BEST answer!
m = -10/4
m = -5/2
m= 0
m = 5/2
Answer:
m= -5/2
Step-by-step explanation:
formula for slope(m) : ΔY/ΔX (change in y coordinates - change in x coordinates)
change in y coordinates: 5-(-5) = 10
change in x coordinates: -4-(0) = -4
10/-4 = -5/2= -2.5

Answer:
Step-by-step explanation:
Amount paid for first 100 watches = (65% of 80) *100
[tex]=\frac{65}{100}*80*100\\\\= 65*80\\= 5200[/tex]
Amount paid for next 50 watches = (55% of 80) * 50
[tex]= \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200[/tex]
Remaining watches = 280 -(100+ 55)
= 280 - 155 = 125
Amount paid for 125 watches = (45% of 80) *125
[tex]= \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500[/tex]
Amount received by the watch maker = 5200 + 2200 + 4500

Are the following equations parallel, perpendicular, or neither?
help me
Answer:
Neither
because parallel equations often have the same exact slop but different y- intercept and nor is it perpendicular because slop must be flipped over 1 and negative so its not evident there.

please help(: ( 8th grade lesson)
Step-by-step explanation:
Since angle 1 is on a straight line and we know that angle 4 is 160, and a straight line has a sum of 180 degrees, simply subtract 160 from 180 to get angle 1.
Angle one would be 180-160 = 20
Since the sum of angles in a triangle is 180 and we already know 2 of them, angle 1 is 20 and angle 3 is 30, just add them together and then subtract that from 180. 20 + 30 = 50, and 180 - 50 = 130.
So in conclusion:
Angle 1 is: 20
Angle 2 is: 130

2) (see image below)
3) x = 8
side(s) = 74
4) x = 10
EF = DE = 67
base = 31
Step-by-step explanation:
For No. 2, if you draw out two triangles with the corresponding angles, you can make it a lot easier. See the image below:
For No. 3, it is given that it's an equilateral triangle, meaning all sides and angles are congruent. So:
12x – 22 = 10x – 6 = 7x + 18
Instead of using all three at once, you can use any two. I'll be using:
12x – 22 = 10x – 6
2x = 16
x = 8
Plugging x in, we can get all the sides, because this is an equilateral triangle:
12x – 22
12(8) – 22
96 – 22
74
For No. 4, it is given that the triangle is an isosceles triangle where DE ≅ EF, so:
8x – 13 = 5x + 17
3x = 30
x = 10
Plugging in x for one of the congruent sides and the base, you can get your needed side length values:
8x – 13
8(10) – 13
80 – 13
67
x + 21
10 + 21
31

Answer:
0.6 inch
Step-by-step explanation:
The volume of a sphere is calculated through the equation,
V = 4πr³/3
Which means that the radius is calculated by the equation,
(3V/4π)^(1/3) = r
Substituting,
Sphere A, (3x30/4π)^(1/3) = r = 1.927 in
Sphere B, (3x10/4π)^(1/3) = r = 1.336 in
When we subtract the radius, we get an answer of 0.59 inch. Therefore, the answer to this item is approximately 0.6 inch.

Seven times the first number plus six times the second number equals 31.
- Three times the first number minus ten times the second number is 29.
WHAT ARE THE TWO NUMBERS
The first number will be [tex]\frac{11}{2}[/tex] and the second number will be [tex]-\frac{5}{4}[/tex].
Let the first number be x and the second number be y.
According to the question,
Since seven times the first number plus six times the second number equals 31. So,
[tex]7x+6y=31.......(1)[/tex]
Similarly,Three times the first number minus ten times the second number is 29.So,
[tex]3x-10y=29.......(2)[/tex]
Multiplying equation (1) by 3 and equation (2) by 7, we get
[tex]21x+18y=93[/tex]
[tex]21x-70y=203[/tex]
Now subtracting both the equations we get,
[tex]88y=-110[/tex]
[tex]y=-\dfrac{110}{88}[/tex]
[tex]y=-\dfrac{5}{4}[/tex]
putting the value of x in equation (1) we get,
[tex]7x+6\times-\dfrac{5}{4} =31[/tex]
[tex]7x-\dfrac{15}{2}=31\\[/tex]
[tex]7x=31+\dfrac{15}{2}[/tex]
[tex]7x=\dfrac{77}{2}[/tex]
[tex]x=\dfrac{11}{2}[/tex]
Hence the first number is [tex]\frac{11}{2}[/tex] and the second number is [tex]-\frac{5}{4}[/tex].
