Heather wants to purchase a pet from her local pet store. The pet store is offering 50% off rare exotic parrots. The original purchase price of a parrot is $956.50. Heather has a coupon for 10% off her entire purchase. How much will she pay if she also purchases a birdcage for $47.05?
$525.66
$478.25
$472.77
$903.20
C) $472.77
Step-by-step explanation: The parrot is half off so it goes from $956.50 to $478.25. Add the bird cage for $47.05 and she has a total of $523.3 to pay. The 10% off coupon makes her need to pay $472.77.
Answer:
$472.77
Step-by-step explanation:
To to this you would just do 50% of 956.50 so you would multiply 956.50 and 50 so you get 48,725 and divide by 100 so you get 487.25 as the price of the bird. So then you you would add 47.05 to the number so you get 525.30 and you would multiply by 10 then divide by 100 so you get 52.53 and subtract that from 525.30 so you get $472.77
The table shows the ratio of nuts to raisins in different snack mixes. Which graph shows these equivalent ratios?
Answer:
figure 3
Step-by-step explanation:
see attached
x coordinates is the nuts
and y coordinates is the raisings
These corresponding ratios are only visible in graph 3.
What is the ratio?The ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
Given, The table shows the ratio of nuts to raisins in different snack mixes.
to compare the graph in Figure 1 with the graph in Figure 2 you would say that as both independent variables increase so do the Raisins.
but the first two graphs are not satisfying the value given in the chart or table.
By comparing Graph 3 and graph 4
SinceNuts should be on the x-axis and raisins on the y-axis
thus only graph 3 is satisfying all the criteria given in the problem.
Therefore, only graph 3 shows these equivalent ratios Also see the attached picture below.

5.71 x 0.8 = 3.26 x 1.45 True or false Need answers quick!!
Answer:
False
Step-by-step explanation:
All you want to do is times 5.71 by 0.8. Once you do that, you'll get 4.568. Then you times 3.26 by 1.45 which gets you 4.727, 4.568 does not = 4.727 which makes the statement false.
Help, Find the domain of the function
Answer:
(-∞,∞)
Step-by-step explanation:
This would form a roughly parabolic shape that extends infinitely along the x-axis. It would reach a height of ³√2 on the y-axis. Because it extends infinitely left and right, it would have an infinite domain. In interval notation, this would be (-∞,∞)
What is the y-intercept of the graph
of 3x - 4y = 12
Pls help
Answer:
Hey there!
3x-4y=12
-4y=-3x+12
y=3/4x-3
So the y-intercept is -3.
Let me know if this helps :)
Answer:
The y-intercept is at (0, -3).
Step-by-step explanation:
Where the graph intercepts the y axis x = 0 so we have the equation:
3(0) - 4y = 12
-4y = 12
y = 12/ -4
y = -3.

a. How many ways can the letters of the word ALGORITHM be arranged in a row?
b. How many ways can the letters of the word ALGORITHM be arranged in a row if A and L must remain together (in order) as a unit?
c. How many ways can the letters of the word ALGORITHM be arranged in a row if the letters GOR must remain together (in order) as a unit?
Answer: a) 362880 b) 40320 c)720
Step-by-step explanation:
a) There are 9 letters in the word ALGORITHM. Pls note that all 9 letters are different.
So to find the number of the ways which the letters can be arranged lets imagine , that in 1st place can stay any of 9 letters, in second place any of remaining 8 letters, in 3-rd place - any of 7 letters etc
So total number of the ways is
N= 9*8*7*6*5*4*3*2*1=9!=362880
b) If A and L must remain togetherin order AL ( LA is forbidden !) so we can imagine that AL is 1 special letter.
So total number of the letters is 8. Similarly to a) we can find the number of the ways as:
N=8*7*6*5*4*3*2*1=40320
c) Similarly to b) lets imagine that GOR is 1 special letter. So there are only 7 letters . Similarly to a) the number of the ways is
N=7*6*5*4*3*2=720
Step-by-step explanation:

An electronics store received two shipments of radios. Of the 250 radios in the first shipment, exactly 6% were damaged. In the second shipment, 4% of the radios were damaged. A total of 24 radios were damaged. How many radios in the combined shipments were NOT damaged? A. 466 B. 441 C. 451 D. 460
Answer:
Total number of not damaged = 451
C. 451
Step-by-step explanation:
In the first shipment, 6% of the 250 radios where damaged.
Number of damaged= 6/100 * 250
Number of damaged= 6*2.5
Number of damaged= 15 radios.
Number of not damaged= 250-15
Number of not damaged = 235 radios
In the second shipment, 4% of the radios were damaged
Let the number of second shipment= y
0.04 of y where damaged
Total number of radio damaged= 24
15 + 0.04y = 24
0.04y= 24-15
0.04y = 9
Y= 9/0.04
Y= 225
Number of radio in the second shipment= 225
Number of damaged in the second shipment= 0.04*225
Number of damaged in the second shipment= 9
Number of not damaged in the second shipment= 225-9
Number of damaged in the second shipment= 216
Total number of not damaged
= 235+216
= 451
Total number of not damaged= 451

1. The speed at which an automated assembly line produces a product follows a normal distribution with mean production time of 32.20 seconds and standard deviation of 1.05 seconds. A full production run from this line consists of 20 completed products. What is the probability that a full production run will take less than 32 seconds on average to produce?2. Recent homebuyers from a local developer allege that 30% of the houses this developer constructs have some major defect that will require substantial repairs. To test this allegation, we randomly sample 20 homes constructed by the developer and find that two of the homes did indeed have some major defect. If the allegation is correct, what is the probability of observing at most two defective homes out of a random sample of 20?3.It is believed that 15% of people who fly on commercial airliners are "very concerned" about the safety of the carrier they have chosen. If this is accurate, what is the probability that out of 150 randomly selected people who fly on commercial airliners, between 20 and 25 of them are "very concerned" about the safety of the carrier which they have chosen?
Answer: Probability = 0.2

Data sets A and B are dependent. Find sd.Assume that the paired data came from a population that is normally distributed.A. 1.73B. 1.21C. 1.32D. 1.89
Answer: A.1.73
Step-by-step explanation:
Given the data:
A : 2.7, 3.7, 5.6, 2.6, 2.7
B : 5.1, 4.0, 3.9, 3.8, 5.2
Difference betweenA and B (A - B) :
Xd = (A - B) = - 2.4, -0.3, 1.7, - 1.2, - 2.5
Sum of (A - B) = Σ Xd = (-2.4 + (-0.3) + 1.7 + (-1.2) + (-2.5) = - 4. 7
Md = ΣXd / n = - 4.7 / 5 = - 0.94
Xd - Md = (-2.4 + 0.94), (-0.3 + 0.94), (1.7 + 0.94), (-1.2 + 0.94), (-2.5 + 0.94)
(Xd - Md) = - 1.46, 0.64, 2.64, - 0.26, - 1.56
(Xd - Md)^2 = (-1.46)^2 + 0.64^2 + 2.64^2 + (-0.26)^2 + (-1.56)^2
Σ(Xd - Md)^2 = (2.1316 + 0.4096 + 6.9696 + 0.0676 + 2.4336) = 12.012
Standard deviation = √[Σ(Xd - Md)^2 / (n-1)]
Standard deviation= √12.012 / 4
Standard deviation = 1.7329
Standard deviation= 1.73
(3 + 2i) + (4 – 5i) solve the equation .
Answer:
7 - 3 i
Step-by-step explanation:
Simplifying
(3 + -2i) + (4 + -5i) = 0
Remove parenthesis around (3 + -2i)
3 + -2i + (4 + -5i) = 0
Remove parenthesis around (4 + -5i)
3 + -2i + 4 + -5i = 0
Reorder the terms:
3 + 4 + -2i + -5i = 0
Combine like terms: 3 + 4 = 7
7 + -2i + -5i = 0
Combine like terms: -2i + -5i = -7i
7 + -7i = 0
Solving
7 + -7i = 0
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + -7i = 0 + -7
Combine like terms: 7 + -7 = 0
0 + -7i = 0 + -7
-7i = 0 + -7
Combine like terms: 0 + -7 = -7
-7i = -7
Divide each side by '-7'.
i = 1
Simplifying
i = 1

A photocopy of a polygon was reduced to 70% of its original size. Then, the copy was again reduced to 70% of its size.
a.is the second photocopy similar to the original?
b.what is the ratio of the corresponding sides of the second photocopy to the original?
Step-by-step explanation:
Step 1 of 4
a) Yes, since the photo copy, is same which is reduced by 80% it remains similar. Because the angles stay the same and the ratios responding sides are proportional.
The following is the figure:

a). Photocopy of a polygon reduced the size of the original polygon by
70%.
But the shape and angles of the the polygon remains unchanged.
Therefore, all the photocopies will be similar to the original polygon.
b). Let the measure of a side of the original polygon measures 'x' unit.
Size of the original polygon gets reduced by 70% in the photocopy.
Then the measure of the side in the photocopy = x - (70% of x)
= [tex]x-\frac{70x}{100}[/tex]
= [tex]x-0.7x[/tex]
= [tex]0.3x[/tex] units
Size of the second photocopy was reduced again by 70%.
Therefore, measure of the side of the second polygon = [tex]0.3x-(\frac{70}{100}\times 0.3x)[/tex]
= [tex]0.3x-0.21x[/tex]
= [tex]0.09x[/tex] units
Ratio of the corresponding sides of the second photocopy and the
original = [tex]\frac{0.09x}{x}[/tex]
= 0.09 : 1

5x - 7x + 6 = -2(x - 3)?
Answer: infinite number of answers
Step-by-step explanation:
5x - 7x + 6 = -2(x - 3) Distribute the -2
5x - 7x + 6 = -2x + 6 Combine like terms on the left side
-2x + 6 = -2x + 6 Add 2x to both sides
6 = 6
This means there’s an infinite number of answers. To test this, you could for example plug in 1 and -1. You’d find that they both solve the equation.
