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!

Answer:
8
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.

Write the standard equation of the circle with center (-12, – 7) that passes through the point (-3,7).
Answer:
[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In which r is the radius.
Center (-12, – 7)
This means that [tex]x_0 = -12, y_0 = -7[/tex]. So
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - (-12))^2 + (y - (-7))^2 = r^2[/tex]
[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]
Passes through the point (-3,7).
This means that we use [tex]x = -3, y = 7[/tex] to find the radius squared. So
[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]
[tex](-3 + 12)^2 + (7 + 7)^2 = r^2[/tex]
[tex]81 + 196 = r^2[/tex]
[tex]r^2 = 277[/tex]
The equation of the circle is:
[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]
[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]

cara played a card game using a deck of 52 cards after she dealt the same number of cards to 4 players she had 24 cards left over how many cards did each player get
Answer:
7Step-by-step explanation:
Assume each player get x cards. Total number of cards now is 4x+24=52.
Therefore, 4x=52-24=28.
Then, x= 28/4=7.

Find the missing sides of the triangle. Leave your answers in simplest radical form.
Answer:
B) x=2, y=2
Step-by-step explanation:
B.
It’s a 90-45-45 triangle, so the hypotenuse is x√2, and the other two sides are x. Since this x is 2, the other two sides are 2.

The Department of Homeland Security wants to test a computer virus that it has developed to combat hackers. They plan to test run the virus on randomly selected computers with pre-set "hacker" programs.
choose one:
-census
-cluster sampling
-convenience sampling
-simple random sampling
-stratified sampling
choose one:
-experiment
-observational study
-simulation
-survey
Answer:
Simple random sampling
Observational study
Step-by-step explanation:
Since in the given situation it is mentioned that department wants to test the computer virus and have to run the virus on the random selected computers so here the simple random sampling would be done and based on the simple random sampling the observational study would be done
Therefore the above represent the answer
Answer:it is simple random sampling but the collection method is not observational study I got that part wrong

Answer:
y=5x+6
Step-by-step explanation:
please help !!!! asap
Answer:
y = 1
Step-by-step explanation:
-3y + 14 + y = 12
-3y + y + 14 = 12
-2y + 14 = 12
-2y + 14 - 14 = 12 - 14
-2y = -2
-2y/-2 = -2/-2
y = 1
Answer:
y=1
Step-by-step explanation:
Hey There!
So to solve this type of problem we use inverse operations
-3y+14+y=12
step 1 subtract 14 from each side
14-14
12-14=-2
now we have
-3y+y=-2
step 2 combine like terms
-3y+y=-2y
now we have -2y=-2
step 3 divide each side by -2
-2/-2=1
so we can conclude that y=1

Volume: 312 cubic inches
Height: 13 inches
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

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
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.

Solve the following problem. Round answer to two decimal places when necessary.
A = 4
B = 9
C = 11
D = A + 2B - C
D = ?
Answer:
D = 11
Step-by-step explanation:
A = 4
B = 9
C = 11
D = 4 + (2 * 9) - 11
D = 4 + 18 - 11
D = 22 - 11
D = 11

-x^2+4x-8
axis of symmerty
Answer:
[tex]\boxed {\boxed {\sf x=2}}[/tex]
Step-by-step explanation:
The axis of symmetry can be calculated using the formula:
[tex]x=\frac{-b}{2a}[/tex]
First we must determine a and b from the quadratic: [tex]-x^2+4x-8[/tex]. This is in standard form, with the highest power first in descending order.
Standard form is also: [tex]ax^2+bx+c[/tex]
If we compare this to the quadratic given, we can conclude that:
[tex]a= -1 \\b= 4 \\c= -8[/tex]
Substitute the values for a and b into the formula.
[tex]x= \frac{-(4)}{2(-1)}[/tex]
Multiply in the denominator.
[tex]x=\frac {-4}{-2}[/tex]
Divide.
[tex]x=2[/tex]
This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.

i’m having trouble on my last one
Answer: 52
Step-by-step explanation:
First, divide 13 by the total amount of shows, 19. Then, divide 76 by 19. This results in 4, which when multiplied by 13, results in 52. To check the answer just divide 52/76 and you should get the same number as with 13/19.
