Answer:
y=-4.2
Step-by-step explanation:
2.9=7.1+y
2.9-7.1=7.1-7.1 +y
-4.2=y or y= -4.2
y = -4.2
If you substitute that value for y into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. HOPE THAT HELPS!

On a coordinate plane, a square has points A (negative 5, 2), B (1, 2), C (negative 4, 1), and D (negative 5, negative 4). If a translation of is applied to square ABCD, what is the y-coordinate of B'?
Answer:
The y coordinates of B' is: 8
Step-by-step explanation:
Given
[tex]A = (-5,2)[/tex]
[tex]B =(1,2)[/tex]
[tex]C = (-4,1)[/tex]
[tex]D = (-5,-4)[/tex]
Translation of (x, y) → (x + 6, y – 10) ---Missing from the question
Required
Determine the y coordinates of B'
We have:
(x, y) → (x + 6, y – 10)
And
[tex]B =(1,2)[/tex]
So the translation from B to B' is:
[tex]B (1,2) \to B'(1+6,2-10)[/tex]
[tex]B (1,2) \to B'(7,-8)[/tex]
So, we have:
[tex]B' = (7,-8)[/tex]
The y coordinates of B' is: 8

In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°
Answer:
14.2cm
Step-by-step explanation:
Complete question:
In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.
Rounded to the nearest tenth of a centimeter, what is the length of arc LMN?
Find the diagram attached
arc LN= arc LM + arc MN
First we need to get the arc MN
length of an arc = theta/360 * 2πr
length of arc MN = 75/360 * 2(3.14)(6)
length of arc MN = 0.20833*37.68
length of arc MN = 7.85
Hence;
arc LN = 6.3 + 7.85
arc LN = 14.15cm
Hence the length of arc LN is 14.2cm

Find the values of x and y.
Answer:
Step-by-step explanation:
y = 5
All sides measure the same So 8y= 40 y = 5
x = 30 degrees
The straight line of 40+40 is a straigth angle of 180 Each angle of equilateral triangle is 60 degrees.So its supplementary is 120.The other 2 angles need to add to 60 (30 each) to sum 180 in a triangle

In the figure to the right, if AC = 21 and BC = 18, what is the
radius?
Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82

Answer:
x = 7
y = 25
Step-by-step explanation:
First, we know that x=7 because has the same hypotenuse (the long side) and also has a right angle.
Now, to find out y. The equation for discovering the hypotenuse is:
c = √(a² + b²)
C is the hypotenuse.
A is one of the shorter sides.
B is also one of the shorter sides.
NOTICE: THIS EQUATION ONLY WORKS FOR RIGHT TRIANGLES.
So, now you just need to fill the equation in:
c = √(7² + 24²)
c = √(49 + 576)
c = √(625)
c= 25
So, now we have y, the hypotenuse!
Hope this helped :D

A skateboard ramp at a park has an inclination of 54º and its base is 12 feet long. What is the length of the ramp?
The length of the skateboard ramp at the park is 20.4 feet.
Trigonometric ratioTrigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let x represent the length of the ramp, hence using trigonometric ratio:
cos(54) = 12/x
x = 12/cos(54)
x = 20.4 feet
The length of the skateboard ramp at the park is 20.4 feet.

If it costs $55,000 to put on a magic show for two weeks in the estimated revenue is $15,000 per night for 14 nights what will the stadiums profit be
Answer:
$155,000
Step-by-step explanation:
You need to first multiply revenue of one night by 14 ($210,000) and then subtract the cost ($55,000) from it. You would get $155,000.
The profit will be $155,000.
What is profit?Profit is the money earned by a business when its total revenue exceeds its total expenses.
Given that the costs $55,000 to put on a magic show for two weeks in the estimated revenue is $15,000, we need to find the profit,
So,
The cost of the magic show for two weeks is given as $55,000, The revenue is estimated as $15,000 per night.
As the show continued for 2 weeks or 14 nights, so the total revenue is,
= 15000 x 14 = $210,000
∵ Profit = Revenue - cost
Profit = $210,000 - $55,000
Profit = $155,000
Hence the profit will be $155,000.
