Answer:
Step-by-step explanation:
Let the starting point be B and the stopping be C as shown in the diagram below.
therefore, the angle at A will be (197-90)degree = 107degree
the angle at B is 45degree, since it is directly south west of C.
therefore the angle at C will be A+B+C=180 degree(sum angle of a triangle)
107+45+C=180
therefore, C=180-107-45=28degree
therefore, using sine rule gives;
sinA/a =sinC/c
sin107/a=sin28/4
0.9563/a=0.4695/4
0.9563/a=0.11736
therefore, a =0.9563/0.11736=8.148=8.1km(approx.)

El Señor Carlos Villa quién Pide al Banco Azteca un crédito de $110000 sobre una tasa del 10% al año su cantidad a pagar será de
Responder:
121 000
Explicación paso a paso:
Dado que :
Monto del crédito = 110.000; este es el monto principal, P del préstamo
Tasa de interés = 10% = 10/100 = 0.1
Usando la relación para determinar el monto a pagar al final del año:
A = P (1 + rt)
A = monto final
A = 110 000 (1 + 0,1 * 1)
A = 11 000 (1 + 0,1)
A = 110 000 (1,1)
A = 121 000
La cantidad a pagar al final del año = 121.000
Prove to me that you're honest — in one minute.
if u answer this ima be hella impresed
Honest people would tell other people what they think honestly. And honestly, I don't know how to answer your question :( Honestly, I feel like I don't deserve to answer this question if I can't come up with an honest answer. I don't know, maybe I come back to this question another day when I'm older and wiser, and have an answer that will impress you with my honesty.

Answer:
(2x +1)/(4x^2) . . . . except x=0, -1
Step-by-step explanation:
Addition of fractions works in the usual way:
a/b +c/d = (ad +bc)/(bd)
Division of fractions works in the usual way:
(a/b)/(c/d) = (ad)/(bc)

A snow storm has blown across the united states. Currently, 30k square miles of land are affected. Each day, the land increases by 30% Equation: How much will the be hit by the snowstorm after 5 days?
Answer:
50,000 Square Miles.
Step-by-step explanation:
30% = 1/3
30,000/1 * 1/3 = 10,000
10,000 * 5 = 50,000

How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution

What is the slope of the equation: y = - 5x -6
What is the y-intercept of the equation: y = 2x
Answer:
Step-by-step explanation:
y = mx +b
Here, m is slope and b is y-intercept
1) y = -5x - 6
Slope = -5
y-intercept = -6
2) y = 2x
Slope = 2
y-intercept = 0

Mars has m moons. The number of moons of Pluto is one more than twice the number of moons of Mars. The number of moons of Neptune is one less than 3 times the number of moons of Pluto. Write and interpret a simplified expression that represents the number of moons of Neptune (I’m just asking to answer because I didn’t see any right ones when I was scrolling through them)
Answer:
neptune = 6m+2
Step-by-step explanation:
mars has 'm' moons
pluto has one more than twice that of mars, = 2m+1
neptune is one less than thrice of pluto
= 3(2m+1) -1
= 6m+3 -1
= 6m+2

Answer:
RQ = 10
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal;
Thus, we have it that;
QP/RQ = BC/AB
12/RQ = 36/30
RQ = 12 * 30/36 = 10

The angle of elevation from a kicker's foot on the football field to the top of the goal post is 17 degrees. If he is standing 131 feet from the base of the goal post, how tall is the goal post?
Answer:
The goal post is 40.05 feet tall.
Step-by-step explanation:First, you need to decide whether to use sin, tan or cos.
You have the angle, the adjacent and need the opposite , so you need to find out which one has all three values in
Sin
Cos
Tan
So you need to use tan.
Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:
[tex]Opp = Tan * adj
So simply plug these values in:
[tex]Opp =131 * tan(17) = 40.05
So the goal post is 40.05 feet tall
