Answer: 4.17%
Step-by-step explanation:
Formula for percentage error = [tex]\dfrac{|\text{Estimated weight - Actual weight}|}{\text{Actual weight}}\times100[/tex]
Given: Estimated weight = 2.5 oz
Actual weight = 2.4 oz
Percentage error = [tex]\dfrac{2.5-2.4}{2.4}\times100\%[/tex]
[tex]=\dfrac{0.1}{2.4}\times100\%\\\\=\dfrac{100}{24}\%=4.17\%[/tex]
Hence, the percent error = 4.17%

1.Encuentra la ecuación de la circunferencia que tiene como ecuación ordinaria (x-4)² + (y+5)²= 25 2- encuentra la ecuación general de la circunferencia que tiene como ecuación ordinaria (x+1)² + (y+9)²=49
Responder:
1) x² + y²-8x + 10y + 16 = 0
2) x² + y² + x + 18y + 33 = 0
Explicación paso a paso:
A partir de la pregunta, debemos expresar la ecuación en la forma estándar de un círculo expresado como;
x² + y² + 2gx + 2fy + c = 0 donde;
(-g, -f) es el centro.
1) Para la ecuación (x-4) ² + (y + 5) ² = 25
Expande el paréntesis;
(x-4) ² + (y + 5) ² = 25
x²-8x + 16 + y² + 10x + 25 = 25
x²-8x + 16 + y² + 10y + 25-25 = 0
Recopile términos similares;
x² + y²-8x + 10y + 16 + 0 = 0
x² + y²-8x + 10y + 16 = 0
Por lo tanto, la ecuación requerida es x² + y²-8x + 10y + 16 = 0
2) Para la expresión (x + 1) ² + (y + 9) ² = 49
x² + x + 1 + y² + 18y + 81 = 49
x² + x + 1 + y² + 18y + 81-49 = 0
Recopile términos similares;
x² + y² + x + 18y + 82-49 = 0
x² + y² + x + 18y + 33 = 0
Por tanto, la ecuación requerida es x² + y² + x + 18y + 33 = 0
which one is greater 3.406 or 3.501
Answer:
hi its 3.501
Step-by-step explanation:
Use elimination to solve the system.
2x + 3y = 1
5x – 4y = 14
help would be appreciated :)
Answer:
x = 2, y = -1
Step-by-step explanation:
To solve this with elimination, we first multiply the first equation by -2.5
Our new equations are:
-5x - 7.5y = -2.5
5x – 4y = 14
After adding these two equations together, the x cancels out and we have:
-11.5y = 11.5
Divide both sides by -11.5
y = -1
Plugging this value into y in one of the equations we have:
2x + 3y = 1
2x + 3(-1) = 1
2x - 3 = 1
Add 3 to both sides
2x = 4
Divide both sides by 2
x = 2
Which expression is equivalent to 2^2divided by 2/2^4
Answer: 32
Step-by-step explanation:
The expression that is equivalent to 2^2 divided by 2/2^4 would be calculated as:
= 2^2 ÷ 2/2^4
= 4 ÷ 2/16
= 4 ÷ 1/8
= 4 × 8
= 32
The expression would be equal to 32 based on the above calculation
Solve the Equation
–x + 8 + 3x = x – 6
A. x = –18
B. x = –14
C. x = 2
D. x = 4
Answer:
x= -14
Step-by-step explanation:
-x+3x-x=-8-6
x= -14
-x+8+3x=x-6
the first thing we need to do is move the x's to the left and the numbers to the right
when moving a number from one side to another it's sign is changed
-x+3x-x=-6-8
x=-14
What is CD??
A.7
B.10
C.13
D.21
Answer:
13
Step-by-step explanation:
Is there more info to this problem? I'm assuming both triangles are congruent. If so then you can assume that BC = CD
If that's the case then set them equal to each other to solve for x then plug x back into the side for CD to get the value
6x-5 = 4x+1
2x = 6
x = 3
Plug into CD 4(3) +1
= 13

2. Find the distance between the points K(-2, 3) and L(4,7)
Answer:
7.21 (7.211103 exact)
Step-by-step explanation:
In this question, we have to find the distance of the two points.
To do so, we would use this equation: d = √(x2-x1)² + (y2-y1)²
Plug in your coordinates and solve:
d = √(4+2)² + (7-3)²
d = √(6)² + (4)²
d = √36 + 16
d = √52
Now, get the square root of 52:
d = 7.211103
The distance of each coordinate would be around 7.21

6x + 4 = 3x +13
Answer:
the answer is 3
Step-by-step explanation:
6x -3x = 13-4
3x = 9
x =3
Answer:
Subtract 4 from both sides of the equation
6+4=3+13
6+4−4=3+13−4
Simplify
Subtract the numbers
6=3+9
Subtract 3 from both sides of the equation
6x=3+9
6−3=3+9−3
Simplify
Combine like terms
3=9
Divide both sides of the equation by the same term
3=9
3/3=9/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
=3
Solution

Answer:
x = 34°Step-by-step explanation:
Use property of exterior angles:
Exterior angle = sum of non-adjacent interior anglesHere we have:
∠D + ∠E = ∠EFG∠EFG = ∠EFH + ∠HFG = 90° + 42° = 132°So the equation is:
2x + 64° = 132°2x = 132° - 64°2x = 68°x = 68°/2x = 34°If you think it is not 34°, then your question must be asking to find something else (e.g. angle D, which is 68°)

Answer:
99,000
Step-by-step explanation:
since 3 times 10 to the power of 3 is 1000 and 10 to the power of 5 is 100000 the answer is 99,000
Answer: 97000 more
Step-by-step explanation:
10*10*10*10*10=100000 10⁵
10*10*10=1000*3=3000 10³
So 100000-3000= 97000 more

Answer:
Y - Adds by -5X - Adds by 2Step-by-step explanation:
It adds by negative 5 because if you add up all of the math and equations, it will all fit together.
Here's an example.
The first one is 3 and -2, so lets add -2 by 5.
-2 + 5 = 3 --- 1st row
We can figure this out by subtracting 2 by 5, which equals 3.
( This does not apply to all equations. )
Let's add all of them by 5 now.
-7 + 5 = -2 --- 2nd row
-12 + 5 = -7 --- 3rd row
On the last row, we add -12 by -5 and you get -17.
-17 + 5 = -12 --- 4th row
That's how you figure it out.
Hope this helps! <3
The distance between two stars is 9.0 x 10 to the power of -3 light years. A light year is equal to
5.88 x 10 to the power of 12 miles. What is the distance, in miles, between the two stars
Answer:
The distance between the two stars in miles is 5.292 * 10^10 miles
Step-by-step explanation:
Here, we want to make a conversion from light year to miles
To make this conversion, we simply are going to multiply the light year by the miles
Mathematically, we have this as;
9 * 10^-3 * 5.88 * 10^12
= 52.92 * 10^9
= 5.292 * 10^10 miles

Step-by-step explanation:
Answer:
a. x = 12
b. x = 4
Step-by-step explanation:
a. [tex]\frac{2x}{3}=8[/tex]
Multiply both sides by 3;

Divide both sides by 2;
x = 12
b. [tex]\frac{3x}{2}=6[/tex]
Multiply both sides by 2;
[tex]\frac{3x}{2}*2=6*2\\\\3x=12[/tex]
Divide both sides by 3;
x = 4

Step-by-step explanation:
PLEASE! 10 POINTS! For what number A does the equation 3Ax - 24 = 5x - 9 + x have no solutions for x?
Answer:
3Ax-6x = 15
3x(A-2)=15
If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2
