Answers
Answer:
Pesos: $20
Dolares: $1
Step-by-step explanation:
Si la moneda mas alta tiene un valor de $20 pesos, tendria que pagar el primer articulo con 35 monedas. $20 x 35 = $700
Tendria que pagar 25 monedas para el segundo articulo. $20 x 25= $500

How many degrees is angle X?
How many degrees is arc ZY?
How many degrees is arc XY?
(Picture is below)
Answers
Answer:
X = 70°arc ZY = 140°arc XY = 82°Step-by-step explanation:
The angle sum theorem helps you compute the angle inside the triangle. The inscribed angle theorem helps you compute the arc measures outside the triangle.
TheoremsThe Angle Sum theorem tells you the sum of angles in a triangle is 180°. That lets you write the equation ...
X +Y +Z = 180°
X +69° +41° = 180°
The Inscribed Angle theorem tells you an inscribed angle has half the measure of the central angle subtending the same arc. The arc and the central angle have the same measure: twice that of the inscribed angle.
arc ZY = 2×∠X
arc XY = 2×∠Z
SolutionsUsing the equations we wrote describing the relationships of the unknowns to the known information, we find ...
X = 180° -110° = 70°
arc ZY = 2×70° = 140°
arc XY = 2×41° = 82°
Answer:Angle x=70°
Step-by-step explanation:interior angles add up to 180° so we add 41° and 69°. After addition,you minus from 180° and you get 70°

From equation i
2x - y = 7.

Why are there two solutions for the equation |6+y| = 2?
Explain.
Answers
Answer:
y=-4 and y=-8
Step-by-step explanation:
When you have an absolute value around something, you can remove it, expect it's like a square root, it's going to be a [tex]\pm[/tex]. Because 6+y could've been -2 and the absolute value just made it positive 2
So set 6+y equal to -2 and 2 to find the two solutions:
6+y = 2
y = -4
6+y = -2
y = -8
Hey there!
YOUR EQUATION: |6 + y| = 2
CONVERT THAT TO:
y + 6 = 2 OR y + 6 = -2
FIRST let’s solve for: y + 6 = 2
y + 6 = 2
SUBTRACT 6 to BOTH SIDES
y = 6 - 6 = 2 - 6
SIMPLIFY THAT!
y = 2 - 6
y = -4
Possible solution #1: y = -4
LASTLY let’s solve for: y + 6 = -2
y + 6 = -2
SUBTRACT 6 to BOTH SIDES
y + 6 - 6 = -2 - 6
SIMPLIFY THAT AS WELL!
y = -2 - 6
y = -8
Possible solution #2. y = -8
Therefore, your answer should be:
y = -4 or y = -8

Answers
The given linear equation has one solution: (-0.6, 1.6). The correct option is the second option one solution: (-0.6, 1.6)
Solving system of linear equationsFrom the question, we are to determine the number of solutions the given linear equation has
The given system of equations is
y = 2/3x+ 2 ---------- (1)
6x - 4y = -10 ---------- (2)
Substitute equation (1) into equation (2)
6x - 4y = -10
6x - 4(2/3x +2) = -10
6x - 8/3x -8 = -10
6x - 8/3x = -10 + 8
10x/3 = -2
10x = -2 × 3
10x = -6
x = -6/10
x = -0.6
Substitute the value of x into equation (1)
y = 2/3(-0.6)+ 2
y = -0.4 + 2
y = 1.6
The solution to the given system of equation is x = -0.6, y = 1.6. That is, (-0.6, 1.6)
Hence, the given linear equation has one solution: (-0.6, 1.6). The correct option is the second option one solution: (-0.6, 1.6)

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at a rate of 65 miles per hour. The westbound train travels at a rate of miles per hour. How long will it take for the two trains to be miles apart
Answers
Answer:
It will take 1 hour and 24 minutes.
Step-by-step explanation:
Given that:
Eastbound train travels at a rate of 65 miles per hour and Westbound train travels at a rate of 85 miles per hour
So speed = 65 + 85 = 150 miles per hour
Total distance = 210 miles
We have to find the time, we know that
Distance = time * speed
OR
Time = distance / speed
Time = 210/150
Time = 1.4 hours
Or it can be written as:
Time = 1 hour 24 minutes

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of ∠BAC = 30°
The adjacent side of the triangle AC = √3 units
The hypotenuse of the triangle AB = 2 units
So , from the trigonometric relations
cos θ = adjacent / hypotenuse
On simplifying , we get
cos ( 30 )° = √3/2
Therefore , the measure of cos ( 30 )° = √3/2
Hence , the trigonometric relation is cos ( 30 )° = √3/2

In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2.
On a coordinate plane, circle Q is centered at the origin with radius r. Triangle P Q S is shown. Point Q is at (0, 0) and points P is at (x, y). The length of Q P is r, the length of P S is y, and the length of Q S is x. Angle P S Q is a right angle.
If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle?
(h + x)2 + (k + y)2 = r2

(k + x)2 + (h + y)2 = r2
