Answers
Answer: The net change to her banking account balance is $83.22.
Step-by-step explanation:
Hi to answer this question we have to analyze the information given:
She spent $36.50 plus 8% tax. ( to calculate the tax amount we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Finally, adding to the total cost.
64.42 +18.8 = $83.22

Which of the following represents the greatest percent of change?
A. Boots that were originally priced at $90 are on sale for $63
B. A baby that weighed 7 pounds at birth now weighs 10 pounds
C. A bracelet that costs $12 to make is sold for $28
D. A savings account increased from $500 to $600 in one year
Answers
Answer:
c
Step-by-step explanation:
a. 63(new) - 90(old) = -27 / 90 = 0.4285*100 = 42.9%
b. 10(new) - 7(old) = 3 / 7 = -0.3*100 = -30 = 30%
c. 28(new) - 12(old) = 14 / 12 = 1.166 * 100 = 116.6%
d. 600(new) - 500(old) = 100 / 500 = 0.2 = 20%
The greatest percentage change will be a bracelet that costs $12 to make and is sold for $28 as 133.33% thus option (C) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
% change = (change)/original x 100
A): (90 - 63)/90 x 100 = 30%
B): (10 - 7)/10 x 100 = 30%
C); (28 - 12)/12 x 100 = 133.33%
D):(600 - 500)/500 x 100 = 20%
Hence "The greatest percentage change will be a bracelet that costs $12 to make and is sold for $28 as 133.33%".

Suppose two $20 bills, three $10 bills, one $5 bill, and seven $1 bills are placed in a bag. If you were to pull a bill at random, what is the expected value for the amount chosen
Answers
Answer:
Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is [tex]\frac{7}{13}[/tex].
Step-by-step explanation:
From the given question, the bag contains;
$1 bill = 7
$5 bill = 1
$10 bill = 3
$20 bill = 2
Total number of bills in the bag = 13
Pulling a bill at random, the bills would have an expected value as follows:
For $1 bill, the expected value = [tex]\frac{7}{13}[/tex]
For $5 bill, expected value = [tex]\frac{1}{13}[/tex]
For $10 bill, expected value = [tex]\frac{3}{13}[/tex]
For $20 bill, the expected value = [tex]\frac{2}{13}[/tex]
Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is [tex]\frac{7}{13}[/tex].

Graph the line
y = - 4/3x + 3
I need help with the steps.
Answers
Start by putting a dot at (0,3). Then you just need to go four down and three right from that dot and put another dot. Just repeat that a couple times to make sure it is straight, and connect the dots with a line. You can also go four up and three left from the (0,3) for the other side of the axis.
Step-by-step explanation:
First look at the y-intercept or b (in this case it is 3)
The y-intercept tells us where the line touches in the graph on the Y-axis
(In this case you move up in the Y-axis 3 times)
Put a dot on 3 (in the y-axis)
Now from 3 on the y-axis go down -4 and right 3 since the slope is -4/3
(Slope = rise/run -4 is rise [but since it the 4 is a -4 you go down] and 3 is run)
every time you finish going down -4 and right 3 place a dot on it and repeat if you think you can draw a line then stop and draw the line and you are finished

approximately what percent interest is he paying?
$
Answers

The percent of interest is he paying is,
⇒ R = 4.62%
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
We have to given that;
Ted is making monthly payments of $77 on a loan of $4,000 for 5 years.
Hence, Yearly payments to pay is,
⇒ 12 × 77
⇒ $924
Hence, We get;
⇒ Interest = PRT/ 100
⇒ 924 = 4000 × R × 5 / 100
⇒ 92400 / 20,000 = R
⇒ R = 4.62%
Thus, The percent of interest is he paying is,
⇒ R = 4.62%

The original Volkswagen Beetle follows
a quadratic curve, write an equation if
the height is 5 feet long and the length
is 14 feet long. Show your work in the
sketchpads below.
Answers
Answer:
[tex]y= -\frac{5}{49}x^{2}+5[/tex]
Step-by-step explanation:
In order to solve this, we need to start by drawing a sketch of what the problem looks like (see attached picture).
From the picture, we can see that the graph of the equation should be a parabola with a vertex located at the point (0,5) and x-intercepts located at (-7,0) and (7,0) respectively.
So, there are two ways in which we can build a quadratic equation:
Standard form:
[tex]y=ax^{2}+bx+c[/tex]
or
Vertex form:
[tex]y=a(x-h)^{2}+k[/tex]
Since we already have the vertex and two points on the equation, we can directly use the vertex form. Where vertex is located at the coordinates (h,k)
So in this case: h=0 and k=5, which simplifies our equation a lot:
[tex]y=a(x-0)^{2}+5[/tex]
[tex]y= ax^{2}+5[/tex]
So we only need to find the value of a for our equation to be complete. We can use either x-intercept to find this. Let's use the point (7,0) so we get:
[tex]0=a(7)^2+5[/tex]
and now we can solve for a:
[tex]-5=49a[/tex]
[tex]a=-\frac{5}{49}[/tex]
so this completes our equation:
[tex]y= -\frac{5}{49}x^{2}+5[/tex]
whose graph looks like the one in the attached picture.

What are Supplementary angles?Two Angles are Supplementary when they add up to 180 degrees.
Given that ∠ A and ∠ B are Supplementary and ∠ A = (3x−23),
∠ B = (2x−12)
According to definition of Supplementary,
∠ A + ∠ B = 180°
(3x−23) + (2x−12) = 180°
5x - 35 = 180°
5x = 180° + 35
5x = 215°
x = 43°
Putting x = 43° in ∠ B = (2x−12)
∠ B = (2*43−12)
∠ B = 86 - 12
∠ B = 74°
Hence, The measurement of ∠ B = 74°

y = (1/2)x - 3
The slope is m = 1/2 and the y-intercept is (0, -3).
Step-by-step explanation:
Assuming that you meant 6y = 3x - 18, we solve this equation for y to obtain the slope-intercept formula y = mx + b for this particular case:
y = (3/6)x - (18/6), or
