The Bath and Bodyworks hand soap is on sale for $3.25. If this price represents a 50% discount from the
original price, what is the original price to the nearest cent?
Answer:
$4.875 Rounded to nearest cent:$4.88
Step-by-step explanation:
50%=0.50
3.25*0.50=1.625
$3.25+$1.625=$4.875
The rule is five or more add one more. So add one to the 7 making it 8. Make sure to take out the five. And you get $4.88
Answer:
$6.50
Step-by-step explanation:
(I submitted and it was right)
3.25 = 50%
3.25 + 3.25 = 6.50
6.50 = 100%
Don't over think it! Best of luck!
In Problems 1 and 2 use Euler's method to obtain a four decimal approximation of the indicated value . Carry out the recursion of ( 3 ) by hand , first using h = 0.1 and then using h = 0.05 .
y’ = x + y^2 , y(0); y(0.2)
I saw on your other question that you mention y (0) = 0. Let
f(x, y) = x + y ²
Now consider the recurrences in Euler's method,
[tex]\begin{cases}x_0=0\\x_n=x_{n-1}+h&\text{for }n>0\end{cases}[/tex]
[tex]\begin{cases}y_0=y(x_0)=0\\y_n=y_{n-1}+f(x_{n-1},y_{n-1})h&\text{for }n>0\end{cases}[/tex]
where h is the step size.
We then approximate y (0.2) in ...
• ... 2 steps for h = 0.1 :
[tex]\begin{cases}x_0=0\\y_0=0\end{cases}[/tex]
[tex]\begin{cases}x_1=x_0+0.1=0.1\\y_1=y_0+f(x_0,y_0)\times0.1=0\end{cases}[/tex]
[tex]\begin{cases}x_2=x_1+0.1=0.2\\y_2=y_1+f(x_1,y_1)\times0.1=0.01\end{cases}[/tex]
so that y (0.2) ≈ 0.01;
• ... 4 steps for h = 0.05 :
[tex]\begin{cases}x_0=0\\y_0=0\end{cases}[/tex]
[tex]\begin{cases}x_1=x_0+0.05=0.05\\y_1=y_0+f(x_0,y_0)\times0.05=0\end{cases}[/tex]
[tex]\begin{cases}x_2=x_1+0.05=0.1\\y_2=y_1+f(x_1,y_1)\times0.05=0.0025\end{cases}[/tex]
[tex]\begin{cases}x_3=x_2+0.05=0.15\\y_3=y_2+f(x_2,y_2)\times0.05=0.0075003125\end{cases}[/tex]
[tex]\begin{cases}x_4=x_3+0.05=0.2\\y_4=y_3+f(x_3,y_3)\times0.05=0.0150031252343798828125[/tex]
so y (0.2) ≈ 0.015.

The y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.
To find the y-intercept of f⁻¹(x), we can start by finding the inverse function f⁻¹(x) first.
Let y = f(x) = 3/4 x + 12
To find f⁻¹(x), we can first swap x and y, and then solve for y:
x = 3/4 y + 12
x - 12 = 3/4 y
4/3 (x - 12) = y
Therefore, f⁻¹(x) = 4/3 (x - 12)
The y-intercept of f⁻¹(x) is the value of f⁻¹(x) when x = 0.
f⁻¹(0) = 4/3 (0 - 12)
= -16
Hence, the y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.

If the area of a rectangular garden is 6x^2 - 9x what is the length if the width is 3x ?
Answer:
A =L×W
Given,
A=6x²-9x
W=3x
Substituting into the main equation
6x²-9x=L×(3x)
3x(2x-3)=L×(3x)
divide both sides by 3x
2x-3=L
L=2x-3

What is the Top Area of the 4-sided prism shown below? (in square inches)
Answer:
Area of the top = 24 square inch
Step-by-step explanation:
Volume of the given prism = Area of the base or top of the prism × Height of the prism
By substituting the values in the formula,
312 = Area of the top × 13
Area of the top = [tex]\frac{312}{13}[/tex]
Area of the top = 24 square inch

RQ= x+1 QP=7 RP=2x+8 solve for RP
Answer:
RP = 8
Step-by-step explanation:
RQ + QP = RP (segment addition theorem)
(x + 1) + 7 = 2x + 8 (substitution)
Add like terms
x + 8 = 2x + 8
8 - 8 = 2x - x
0 = x
x = 0
✔️RP = (x + 1) + 7
Plug in the value of x
RP = (0 + 1) + 7
RP = 1 + 7
RP = 8

can someone find the slope intercept equation thanks and can you explain it
Answer:
the slope is -2x
Step-by-step explanation:
Its negative because the line is going towards the negatives, and 2 because the slope is rise over run. the line is going up 2 and over 1, which means 2/1, which simplifies to 2
Answer:
-2x -2
Step-by-step explanation:
The slope is negative because it is going down instead of up
y intercept is -2
Use rise over run
Rise is y x is run select 2 points and check rise/run
Slope= - x -(y)

Can someone help me on problem one and if you can and only if you want can you also help me on two btw please show work I will give branily crown thing.
Answer:
17/15 _53/6
Step-by-step explanation:
The other is problem 1 and the other is problem 2
PROBLEM #1:
As the problem is, we are adding a negative. I can change this to be a subtraction problem. It looks like this: [tex]2\frac{1}{3} - 1\frac{1}{5}[/tex].
To be able to add or subtract fractions/mixed numbers, we have to first get common denominators. A common denominator is a shared multiple between two numbers. So, we need to find the smallest number that both 3 and 5 (the denominators of each fraction) can do into evenly. In this case, that number is 15! To transform the fractions to have common denominators, we will multiply 1/3 by 5/5 and 1/5 by 3/3 (multiply the top and bottom by 5 or 3 so that the denominator is 15). Here is our new problem: [tex]2\frac{5}{15} - 1\frac{3}{15}[/tex].
All that's left to do now is subtract! Since our first fraction is larger (this is important!) we don't need to do any borrowing. So, we'll subtract 2 - 1 = 1, and 5/15 - 3/15 = 2/15. Therefore, if we put those pieces back together, we get 1 2/15 ([tex]1\frac{2}{15}[/tex]).
PROBLEM #2:
For this problem, we have two negative mixed numbers. In this case, we will simply be adding the negative numbers because both are negative. For example, -2 + -4 = -6. Here is the rewritten problem: [tex]-3\frac{1}{2} + -5\frac{1}{3}[/tex].
Our first step is to get common denominators. In this case, that common denominator will be 6: [tex]-3\frac{3}{6} + -5\frac{2}{6}[/tex].
Now, we have to add! -3 + -5 = -8, -3/6 + -2/6 = -5/6. Once we've added the parts, we can put them back together to form the answer: -8 5/6 ([tex]-8\frac{5}{6}[/tex]).

Step-by-step explanation:
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode. Therefore if you look at the chart you can see that one more people get 8 than 9, 10, or 5.

Dylan delivers parcels.
On Thursday, he delivered 10% more parcels than on Wednesday.
On Friday, he delivered 50% fewer parcels than on Thursday.
On Friday, he delivered 77 parcels.
Calculate the number of parcels delivered by Dylan on Wednesday.
Answer:
Dylan delivered 140 parcels on Wednesday.
Step-by-step explanation:
On Wednesday:
On Wednesday, he delivered x parcels.
Thursday:
10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x
Friday:
50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.
THis is equals to 77. So
[tex]0.5*1.1x = 77[/tex]
[tex]x = \frac{77}{0.5*1.1}[/tex]
[tex]x = 140[/tex]
Dylan delivered 140 parcels on Wednesday.
How many different 12 member juries can be chosen from a pool of 20 people?
Answer:
1,007,760
Step-by-step explanation:
This is a question that bothers on selection
Using the combination formula
nCr = n!/(n-r)!r!
20C12 = 20!/(20-12)!12!
20C12 = 20!/8!12!
20C12 = 20*19*18*17*16*15*14*13*12!/8!12!
20C12 = 20*19*18*17*16*15*14*13/8!
20C12 = 20*19*18*17*16*15*14*13/8*7*6*5*4*3*2
20C12 = 5,079,110,400/5040
20C12 = 1,007,760
Hence this can be done 1,007,760 different ways
