The percent error in the kitchen scale's measurement is found using the formula ((Measured Value - Actual Value) / Actual Value) × 100%, resulting in a 25% error when comparing the scale's reading of 2 pounds to the actual weight of 1.6 pounds.
Explanation:The question asks to find the percent error for a kitchen scale when measuring the weight of a piece of fruit. The percent error is a way of comparing the accuracy of a measurement to the actual value, and it's calculated using the formula: Percent Error = ((|Measured Value - Actual Value|) / Actual Value) × 100%. In this case, the measured value is 2 pounds and the actual value is 1.6 pounds.
First, subtract the actual value from the measured value: 2 - 1.6 = 0.4 pounds. Then, divide this difference by the actual value: 0.4 / 1.6 = 0.25. Finally, multiply by 100% to find the percent error: 0.25 × 100% = 25%.
Therefore, the percent error for the kitchen scale is 25%. This calculation helps in understanding the accuracy and reliability of measurements taken by the scale.
What is the next number and why ? 1,3,11,35,99,_
Answer: 241
Step-by-step explanation:
This is a simple problem when using Pascal's triangle. First you look at 1 - 3, what is the difference in these 2 numbers? Its 2, then you look at 3 and 11, the difference is 8, then 11 and 35, the difference is 24. If you keep doing this you get; 2 8 24 64 142. Next you find out how these numbers are different. In the end you keep doing this until you get to the triangles point or the differences converge.
1 3 11 35 99 241
2 8 24 64 142
6 16 40 78
10 24 38
14 14
In the end we get 14 but there is no difference in the numbers so we cant go any farther. Hope this helps!
What is the inverse of y=(x-6)^2 +2 ?
Answer:
Step-by-step explanation:
Answer:
x=√y+2 + 6
Step-by-step explanation:
y=(x-6)^2+2
Substrate 2 from both sides
y-2=(x-6)^2
Square root both sides
√y-6=x-6
Add 6 to both sides
√y-6 +6= x
Therefore,x=√y-6 + 6

H(y)=9/5 • 2y at y=-2
Answer:
[tex]H( - 2) = - 7 \frac{1}{5} [/tex]
Step-by-step explanation:
We want to evaluate the equation
[tex]H(y) = \frac{9}{5} \times 2y[/tex]
at y=-2
We just have to substitute to obtain;
[tex]H( - 2) = \frac{9}{5} \times 2 \times - 2[/tex]
We now multiply to get:
[tex]H( - 2) = \frac{9}{5} \times - 4[/tex]
This is the same as:
[tex]H( - 2) = \frac{9}{5} \times \frac{ - 4}{1} [/tex]
We multiply the numerators separately and denominators separately to get:
[tex]H( - 2) = \frac{9 \times - 4}{5 \times 1} [/tex]
[tex]H( - 2) = \frac{ - 36}{5} [/tex]
This implies that
[tex]H( - 2) = - 7 \frac{1}{5} [/tex]

The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.
Step-by-step explanation:
Step 1:
To determine if the function represents growth or decay, we substitute values to x.
If the values increase with an increase of x, it represents growth.
If the values decrease with an increase of x, it represents decay.
Step 2:
If [tex]x= 10,[/tex] [tex]y = 1,300 (\frac{1}{2})^{\frac{10}{69} } = 1,300 (0.9044) = 1,175.72.[/tex]
If [tex]x=11,[/tex][tex]y = 1,300 (\frac{1}{2})^{\frac{11}{69} } = 1,300 (0.8953) = 1,163.89.[/tex]
So as x increases the value of y decreases, so it represents decay.
Step 3:
The percentage rate of change is determined by dividing the difference of two consecutive values by the first value.
The percentage rate of change [tex]= \frac{y(x=11) - y(x=10)}{y(x=10)}.[/tex]
Substituting the values, we get
The percentage rate of change [tex]=\frac{1,175.72-1,163.89}{1,175.72}(100) = 1.00619\%[/tex].
As the values of y decrease with an increase in x, it is the percent decrease per unit.
Answer:
The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.

Which relation is not a function?
[tex]y = \pm\sqrt{x}[/tex]
==================================================
Explanation:
The plus/minus indicates we have two equations, and they are
[tex]y = \sqrt{x} \text{ or } y = -\sqrt{x}[/tex]
If x is say x = 4, then y is both y = 2 and y = -2 at the same time.
A function is where any x input leads to exactly one and only one y output (assuming the x value is in the domain). Graphing out choice D shows that it fails the vertical line test. This is where a vertical line crosses through more than one point on the graph. For the other answer choices, it is impossible to draw a vertical line through more than one point on the graph, which visually shows they are functions.
jenna brought a spool of ribbon that was 5 3/4 meters long. she used 3 1/4 meters of ribbon for a craft project. how many meters of ribbon does jenna have left?
Answer:
So the answer will be 2 2/4
Step-by-step explanation:
If you need me to explain more please tell me.Hope it helps.
Jenna is left with 2 1/2 meters of ribbon for future projects.
Jenna bought a spool of ribbon that was 5 3/4 meters long and used 3 1/4 meters of it for a craft project. To calculate how much ribbon she has left, we need to subtract the length of the ribbon used from the total length of the ribbon.
Convert mixed numbers into improper fractions: 5 3/4 = (5 × 4) + 3 = 23/4 and 3 1/4 = (3 × 4) + 1 = 13/4.
Subtract the second fraction from the first: 23/4 - 13/4 = (23 - 13)/4 = 10/4.
Simplify the result: 10/4 = 2 2/4 = 2 1/2 meters.

how do you do this
Answer:
3bzycukznwvy knsheuje6d9qk3vhdurkgyvuf6dyguts bl es yvhuv
Answer:
g = 20
Step-by-step explanation:
−2 (g − 13) + 15 = 1
Step 1: Simplify both sides of the equation.
−2 (g−13) + 15 = 1
(−2) (g) + (−2) (−13) + 15 = 1 (Distribute)
−2g + 26 + 15 = 1
(−2g) + (26 + 15) = 1 (Combine Like Terms)
−2g + 41 = 1
−2g + 41 = 1
Step 2: Subtract 41 from both sides.
−2g + 41 − 41 = 1 − 41
−2g = −40
Step 3: Divide both sides by -2.
−2g/−2 = −40/−2
g = 20

chords ac and bd intercept at e if ae=6 ec=12 and dc=18 how long is be
Option A:
The length of BE is 4.
Solution:
Given data:
AE = 6, EC = 12 and DE = 18
To find the length of BE:
If two chords intersect in a circle, then the product of lengths of one segment is equal to the product of lengths of other segment.
⇒ AE × EC = DE × BE
⇒ 6 × 12 = 18 × BE
⇒ 72 = 18 × BE
Divide by 18 on both sides of the equation.
⇒ 4 = BE
Switch the sides.
⇒ BE = 4
The length of BE is 4.
Option A is the correct answer.
Which graph shows the solution to the system of linear inequalities below? y>2x+1 y<2x-3
Option D: Graph C is the solution to the system of linear inequalities.
Explanation:
The system of linear inequalities are [tex]y \geq 2 x+1[/tex] and [tex]y<-2 x-3[/tex]
Let us graph the inequality [tex]y \geq 2 x+1[/tex]
Let us substitute the coordinate [tex](0,0)[/tex] in the inequality [tex]y \geq 2 x+1[/tex], we get,
[tex]0 \geq 2 (0)+1[/tex]
[tex]0 \geq1[/tex]
This is false. Hence, the solution does not contain the coordinate [tex](0,0)[/tex]
Thus, let us shade the upper part of the line in the graph.
Similarly, let us substitute the coordinate [tex](0,0)[/tex] in the inequality [tex]y<-2 x-3[/tex], we get,
[tex]0<-2 (0)-3[/tex]
[tex]0<-3[/tex]
This is false. Hence, the solution does not contain the coordinate [tex](0,0)[/tex]
Thus, let us shade the lower part of the line in the graph.
The solution to the system of linear inequality is the intersection of the two regions.
Thus, the solution of the inequality is Graph C.
Hence, Option D is the correct answer.

what is the simple interest , help asap . thank you .
$ 850 , 4% , 6 months
Answer:
I = 2.04.
Step-by-step explanation:
From the question we are asked that what is the simple interest ,
$ 850 , 4% , 6 months
using the formula
simple interest = prt/100
I = interest
P= principal
R = rate.
our P = $850
R = 4% = 4/100 = 0.04
T = 6months
I = (850 × 0.04 × 6)/ 100
I = 204/100
I = 2.04.
Determine all the zeros of m(x) = x² - 4x + 3 , algebraically
The values of the zero are 1 and 3 if the quadratic function is m(x) = x² - 4x + 3 after solving algebraically.
What is a quadratic equation ?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have quadratic function:
m(x) = x² -4x + 3
m(x) = x² -x - 3x + 3
m(x) = x(x -1) -3(x - 1)
m(x) = (x - 1)(x - 3)
x -1 = 0 or x -3 = 0
x = 1 or x = 3
Thus, the values of the zero are 1 and 3 if the quadratic function is m(x) = x² - 4x + 3 after solving algebraically.

The zeros of the quadratic function m(x) = x² - 4x + 3 are found using the quadratic formula, yielding two solutions, x = 1 and x = 3.
To find the zeros of the quadratic function m(x) = x² - 4x + 3, we first note that it is already in standard form, with a = 1, b = -4, and c = 3. The quadratic formula, which states if ax² + bx + c = 0, then x = (-b ± √(b² - 4ac)) / (2a), can be used to find the solutions. Substituting the values, we get:
x = (4 ± √((-4)² - 4(1)(3))) / 2(1)
x = (4 ± √(16 - 12)) / 2
x = (4 ± √4) / 2
x = (4 ± 2) / 2
This results in two solutions:
x = (4 + 2) / 2 = 6 / 2 = 3
x = (4 - 2) / 2 = 2 / 2 = 1
Therefore, the zeros of the function m(x) are 1 and 3.

(x + 15)
(4x - 20°
x = 40
Answer:
Option D, x = 40
Step-by-step explanation:
Since x and (4x - 20) are supplementary, that means they add up to 180 degrees.
Step 1: Make an equation
x + (4x - 20) = 180
Step 2: Combine like terms
x + 4x - 20 = 180
5x - 20 = 180
Step 3: Add 20 to both sides
5x - 20 + 20 = 180 + 20
5x = 200
Step 4: Divide both sides by 5
5x / 5 = 200 / 5
x = 40
Answer: Option D, x = 40

Use the distributive property to solve : 20 (30 - 15) =
Answer:
the distribute property is basically taking the number outside the parenthesis and multiplying with the numbers inside each by each.
Step-by-step explanation:
20(30-15)
20×30= 600, and 20×15=300
finally you just use the new numbers and solve the solution which is 600-300. The answer is 300
Answer: 300
Step-by-step explanation: The distributive property tells us that when there's a number outside a set of parentheses, you can multiply it times each of the terms that are inside the set of parentheses and then add those products together.
So in this problem, we can multiply 20 (30) - 20 (15) which simplifies to 600 - 300 which is 300.

Each peach costs $0.56 and the equations used to solve that is [tex]4x= 2.24[/tex] where x is the cost of 1 peach.
Step-by-step explanation:
Step 1:
It is given that all the peaches weigh the same and that 4 peaches weigh 1 pound.
Assume that each peach costs x.
So the cost for 4 peaches is given by [tex]4x.[/tex]
Step 2:
The cost of 1 pound of peaches is given as $2.24.
1 pound of peaches[tex]=4x.[/tex]
So [tex]4x= 2.24, x = \frac{2.24}{4}.[/tex]
[tex]x = 0.56.[/tex]
So each peach costs $0.56.
If twice a number, n, is 5 less than the number squared, which of the following equations could be used to properly solve for n?
Answer:
2n - 5 = n^2 (or n squared)
The equation that could be used to properly solve for n is [tex]n^2 - 2n - 5 = 0[/tex]
Mathematical equationsTo properly solve for the number, n, based on the given information, you can use the equation:
[tex]2n = n^2 - 5[/tex]
This equation represents the statement "Twice a number, n, is 5 less than the number squared." It sets the twice of the number (2n) equal to the number squared minus 5 (n^2 - 5).
To solve for n, you can rearrange the equation as follows:
[tex]n^2 - 2n - 5 = 0[/tex]
You can then solve this quadratic equation for n using methods such as factoring, completing the square, or the quadratic formula.
