Your local shoe store anticipated giving away 2,500 pairs of shoes in one month, but they only sold 2,215 pairs of shoes. What was the approximate percent error? Show your work to find the percent error.
Answer:
= 11.4%
Step-by-step explanation:
Percent error = (target - actual)/target * 100
target = 2500
actual = 2215
Lets substitute in
Percent error = (2500-2215)/2500 * 100
= 285/2500*100

Write an equation for the parabola shown in the picture.
Answer:
D
Step-by-step explanation:
First, he parabola has a sideways orientation. This signals that x and y have been reversed within the equation meaning [tex]x^{2} --->y^{2}[/tex]. We first look for answers for which y has been raised to the seocnd power instead of x. This leaves answer choice a, b, and d.
Second, we find the vertex of the parabola (center point of the U) at (2,-3). We write them with inverse signs. (x-2) since 2 is the x-coordinate. (y+3) since -3 is the y-coordinate.
The only answer choice meeting these requirements is D.
D. x-2 = (-2/9)(y +3)^2
Step-by-step explanation:The parent function, x = y^2 is translated 2 units to the right and 3 units down. This means x is replaced by x-2, and y is replaced by y+3.
There is also a horizontal scale factor involved. It is useful to use the point (0, 0) to determine what it is.
... (x -2) = a(y +3)^2 . . . . . the translated function with unknown factor "a"
... 0 -2 = a(0 +3)^2 . . . . . .substitute (x, y) = (0, 0)
... -2 = 9a . . . . . . . . . . . . . simplify
... a = -2/9 . . . . . . . . . . . . .divide by the coefficient of "a"
So, the graph is described by ...

If the length of one base of a trapezoid is 5, the length of the other base is 2x + 7, and the length of the midsegment is 6x – 24, what is the value of x? Show equations and all work that leads to your answer.
Answer:
x = 6
Step-by-step explanation:
The midsegment of a trapezoid is the line parallel to the parallel sides of the trapezoid, which connects the midpoints of the non-parallel sides.
The length of the midsegment of the trapezoid is half the sum of the length of the parallel sides.
i.e,
Length of the midsegment = (1/2) *(Length of base1 + Length of base2)
6x - 24 = (1/2) * (5 + 2x + 7)
12x - 48 = 2x + 12
10x = 60
x=6
∴ x = 6
A bond purchased at $500.00 now has a value of $650.00 what is the percent increase of its value?
Answer: A bond purchased at $500.00 now has a value of $650.00 what is the percent increase of its value?
To make it simple for you, the final ANSWER is a 30% increase, due to the fact that taking $500.00 and multiplying that by 0.3 gives you 150, which you add on to 500, giving you 650. Hope that helps!
Answer: The required percent increase in the bond's value is 30%.
Step-by-step explanation: Given that a bond purchased at $500.00 now has a value of $650.00.
We are to find the percent increase of the value of bond.
According to the given information, we have
Purchasing value of the bond = $500.00
and
present value of the bond = $650.00.
So, increase in the value of the bond = $(650.00 - 500.00) = $150.00.
Therefore, the percent increase of the bond's value is given by
[tex]\dfrac{150.00}{500.00}\times 100\%=\dfrac{3}{10}\times 100\%=30\%.[/tex]
Thus, the required percent increase in the bond's value is 30%.

In △ABC, AD and BE are the angle bisectors of ∠A and ∠B and DE ║ AB . Find the length of DE if perimeter of ABDE is 30 cm and AB = 12 cm
Answer:
DE = 6 cm
Step-by-step explanation:
Let DE = x cm.
Since DE is parallel to AB therefore by the alternate interior angles theorem, m∠BAD = m∠ADE and m∠ABE = m∠DEB ............(1)
As AD is an angle bisector of ∠A, therefore m∠EAD = m∠DAB ; Since BE is an angle bisector of ∠B ⇒ m∠ABE = m∠EBD.
Therefore, from (1) We get , m∠EAD = m∠ADE and m∠EBD = m∠BED.
So, the triangles ADE and EDB are then isosceles with AE = ED and ED = DB.
So AE = DE = DB = x, and since the perimeter of ABDE is 30 cm, then
12 + x + x + x = 30
⇒ 12 + 3x = 30
⇒ x = 6
Hence, the length of DE is 6 cm.
Answer:
DE=6cm
Step-by-step explanation:
Let x=DE, since AB║DE, therefore ∠BAD=∠ADE and ∠ABE=∠BED. (1)
Also, we are given that AD is the angle bisector of ∠A and BE is the angle bisector of ∠B,
Therefore, ∠EAD=∠DAB and ∠ABE=∠EBD (2)
From (1) and (2), ∠EAD=∠ADE and ∠EBD=∠BED
⇒The ΔADE and ΔEDB then becomes the isosceles triangle with AE=Ed and ED=DB (Sides opposite to equal angles are always equal)
Therefore, AE=DE=DB=x
We are given that the perimeter of ABDE is 30 cm, therefore,
Perimeter of ABDE= sum of all the sides of ABDE
⇒30=AB+BD+DE+AE
⇒30=12+3x
⇒30-12=3x
⇒x=6cm
Therefore, the length of DE= 6cm

A salesperson at a clothing store earns a commission of 2.5% on all the sales he makes. Which inequalities represent the sales, s, in dollars, he needs to make to earn a commission of more than $100
Answer:
Option A is correct.
Inequality represents the sale s in dollars:
[tex]0.025s\geq 100[/tex]
[tex]s> 4000[/tex]
Step-by-step explanation:
Let s represents the sales in dollars.
Given :A salesperson at a clothing store earns a commission of 2.5% on all the sales he makes.
Earns a Commission = 2.5% of s = [tex]\frac{2.5}{100} \times s = \frac{25s}{1000} = 0.025s[/tex]
It is also given that he needs to make to earn a commission of more than $100
then, we have an inequality:
[tex]0.025s\geq 100[/tex]
divide both sides by 0.025 we get;
[tex]s> 4000[/tex]
Therefore, an inequality represents the sales in dollar ; [tex]0.025s\geq 100[/tex] or [tex]s> 4000[/tex]
Answer:
s > 4,000, s > 4,000
Step-by-step explanation:
Since he needs to make $100 the choices that give him $100 or more are correct.

A contaminant is found in a solution at a level of 3/500%. What fraction of the solution is this
Answer:3/5
Step-by-step explanation:
First we change 500% to fractions
Changing percentage to fraction is dividing the number by 100
500% = 500/100
Putting this we get 3/(500/100)
Then when a number is being divided by a fraction, to get the answer, we multiply the number by the inverse of the fraction
3/(500/100) = 3 x 100/500 = 300/500 = 3/5
If contaminant is found in a solution at a level of 3/500%. Then 3/5 is fraction of the solution
What is Fraction?A fraction represents a part of a whole.
Given,
A contaminant is found in a solution at a level of 3/500%
Let us convert five hundred percentage to a fraction.
500% is converted to fraction by dividing 500/100
So let us divide three by 500/100
3/ (500/100)
When a fraction is divided with another fraction, then the denominator is multiplied inversely with numerator
3×100/500
=300/500
3/5
Hence if contaminant is found in a solution at a level of 3/500%. Then 3/5 is fraction of the solution

What is the length of the midsegment of the trapezoid made by the vertices A(0, 5), B(3, 3), C(5, -2) and D(-1, 2). Show equations and all work that leads to your answer.
Answer:
[tex]\frac{3\sqrt{13} }{2}[/tex]
Step-by-step explanation:
First we have to identify the parallel sides of the trapezium.
We know that the slopes are equal for parallel lines.
Slope of (x₁,y₁) and (x₂,y₂) is given by
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Slope of AB:
[tex]m_{AB} = \frac{3-5}{3-0}=-\frac{2}{3}[/tex]
Slope of BC:
[tex]m_{BC} = \frac{-2-3}{5-3}=-\frac{5}{2}[/tex]
Slope of CD:
[tex]m_{CD} = \frac{2+2}{-1-5}=-\frac{4}{6}=-\frac{2}{3}[/tex]
Slope of DA:
[tex]m_{DA} = \frac{2-5}{-1-0}=3[/tex]
We see that the slopes of AB and CD are equal, so, AB and CD are the parallel sides.
The length of the midsegment = (1/2)*(length of base1 + length of base2 )
Length of the bases can be calculated using distance formula,
[tex]d= \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
AB = [tex]\sqrt{(3-0)^{2}+(3-5)^{2}}= \sqrt{9+4} =\sqrt{13}[/tex]
CD = [tex]\sqrt{(-1-5)^{2}+(2+2)^{2}}= \sqrt{36+16} =\sqrt{52}=2 \sqrt{13}[/tex]
Length of the midsegment = (1/2) (√13 + 2√13) =3√13/2
Orlando invested $16,000 in an eight-year CD bearing 6.5% simple annual interest, but needed to withdraw $3,500 after five years. If the CD’s penalty for early withdrawal was one year’s worth of interest on the amount withdrawn, when the CD reached maturity, how much less money did Orlando earn total than if he had not made his early withdrawal? a. $227.50 b. $682.50 c. $910.00 d. $455.00
Answer:
Therefore, the correct option is OPTION C.
Step-by-step explanation:
If Orlando had not made his early withdrawal, the amount of money he would have earned is:
F = 0.065($16,000)(8) = $8.320
Given that he withdraw $3500, he now earns:
F1 = (0.065)($16,000)(5) + ($12,500)(0.065)(3)
F1 = $5200 + $2437.5 = $7637.5
And now we have to take into acount the year of penalty, which is one year’s worth of interest on the amount withdrawn.
Penalty= $3500(0.065)(1) = $227.5
So the total money he earns now is: $7637.5 - $227.5 = $7410
Then, the amunt of money he could have earn but he didn't is:
Money = $8.320 - $7410 = $910
Therefore, the correct option is OPTION C.

If you answer this I will mark you brainy!!! In an appropriate environment, guppies reproduce at an astounding rate. a population of breeding guppies doubles every 2 months. How many guppies will there be after 6 months if the beginning population is 180 guppies? A. 1440 guppies B. 1080 guppies C. 360 guppies D. 2880 guppies
The correct answer is A, 1440 guppies.
Answer:
Option A. 1440 guppies
Step-by-step explanation:
In an appropriate environment, the population of breeding guppies doubles every 2 months.
Initial population of guppies = 180
after 2 months they doubles = 180 × 2 = 360
after 4 months they doubles = 360 × 2 = 720
after 6 months they doubles again = 720 × 2 = 1440
After 6 months guppies population would be 1440.
A ball is dropped from a height of 5ft and bounces to 60% of I?ts previous height in each subsequent bounce
Answer:
Im assuming youre trying to answer what is the 60% height, it would be 3ft
Step-by-step explanation:
The height of the ball follows a geometric sequence where each subsequent bounce reaches 60% of the height of the previous bounce. The height continues to decrease but does so following a consistent pattern of 60% reduction with each bounce.
Explanation:The problem presented involves the bouncing of a ball and is described as a geometric sequence because each bounce is a constant ratio (60% or 0.6) of the previous height. To understand this sequence, we need to look at it step by step.
Initially, the ball is dropped from a height of 5ft therefore, the initial height is 5ft. With each subsequent bounce, the ball bounces to 60% of its previous height. The height after the first bounce would be 0.6 times the initial height, which equals to 0.6*5 = 3ft. After the second bounce, the height would be again 60% of the previous height, which calculates to 0.6*3 = 1.8ft. This continues for each subsequent bounce.
So, the height of the ball after each bounce decreases but it follows a constant pattern - every next height is 60%, or 0.6, of the previous one, which is a characteristic of geometric sequences.

Erin has a balance of $1,150.34 in her check register. On her statement, the balance of her account is $844.93. Not reported on the bank statement are deposits of $125.56, $50, and $212.34. There are outstanding checks in the amount of $15 and $78.25 and an ATM withdrawal of $40. After Erin reconciles her check register with her statement, what entry does she need to make in her register?
Answer:
D- -50.76
Step-by-step explanation:
Answer:
Erin must first reconcile her bank account:
She must add to her bank balance all the deposits in transit = $125.56 + $50 + $212.34 = $387.90
then she should subtract all outstanding checks = $15 + $78.25 = $93.25
reconciled bank statement = $844.93 + $387.90 - $93.25 = $1,039.58
if her check register shows a $1,150.34 balance and her reconciled bank statement is $1,039.58, then there is a $10.76 difference that must be accounted for.
The $10.76 are probably bank fees and charges that Erin has not recorded yet. Therefore, she should check her bank statement and look for any charged fees (ATM withdrawal charges + account fees) and then record them properly.
*ATM withdrawals are automatically recorded by the bank, so they do not have to be considered in the reconciliation, there is no such thing as outstanding ATM withdrawal.

D. { (3,9), (7,-4), (7,6), (-7,7) }
Answer:
B
Step-by-step explanation:
i took a test with this question
We want to see which one of the given relations is a function.
The correct options are:
B and C.
To see this, we first need to define what a function is.
A function is a relationship that maps elements from one set, the domain, into another set, the range.
Such that each element in the domain can be mapped into only one element on the range.
The standard notation to these relations is (x, y).
This means that x, from the domain, is being mapped into y, from the range.
Now let's analyze the given options:
A) {3,7,-7,9}
This is just a set of values, no relation there, so this is not a function.
B) { (3,9), (7,-4), (-7,7) }
Here we have a relation, and we can see that each element on the domain is being mapped into only one element from the range, so this is a function.
C) { (3,9), (7,-4), (-7,7) }
This is the exact same set as the one on B.
D) { (3,9), (7,-4), (7,6), (-7,7) }
Here we can see that the element x = 7 is mapped into two different values, so this is not a function.
Then the options that represent functions are B and C.

Angle A = 62.1 degrees
Angle X corresponds to angle A
The triangles are not similar
=========================================
Explanation:
To find angle A, subtract the given angles B and C from 180 to get 180 - B - C = 180 - 60.8 - 57.1 = 62.1 degrees
Notice how none of the angles of triangle ABC have a measure of 59.1, so this means that angle Y cannot be congruent to any of A, B or C. This is why the triangles are not similar. We would need 2 pairs of congruent angles to use the AA (angle angle) similarity theorem.
If the triangles were similar, then we can say triangle ABC is similar to triangle XYZ. The letters A and X are the first letters mentioned of the trio of letters, which means that they correspond to one another.
