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.
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
12ft long, 3.5ft width, 1.25ft tall. What is the volume?
Answer:
52.5

You need to multiply l*w*h (length times width times height). In this case, the equation would be 12*3.5*1.25, which would equal 52.5.
Answer:
52.5
Step-by-step explanation:
length*width*hight

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%

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)
-2
-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.
Please help me with this
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.

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

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
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]).
Hope this helps!! :)
