Answer:
C
Step-by-step explanation:
The formula for finding the distance between 2 points (x1, y1) and (x2, y2) is
d = √[(x2 - x1)² + (y2 - y1)²]
Here (x2, y2) = (2, 3) and (x1, y1) = (4, -3)
Plugging them gives us
d = √[(2 - 4)² + (3 - (-3))²]
d = √[(2 - 4)² + (3 + 3)²]

Answer: x = 13
Step-by-step explanation:
To find the value of x, you have to find ∠QRP
∠QRP + ∠QRS = 180
∠QRP + 95 = 180
Subtract 95 from both sides
∠QRP = 85
∠RQP + ∠QPR + ∠QRP = 180 Definition of triangle
(4x + 3) + (3x + 1) + 85 = 180
Subtract 85 from both sides
(4x + 3) + (3x + 1) = 95
7x + 4 = 95
Subtract 4 from both sides
7x = 91
Divide 7 from both sides
x = 13
Find the mean median range and mode for 3, 3, 4, 8, 9, 10, and 12
Answer:
Mean: 7
Median: 8
Range: 9
Mode: 3
Step-by-step explanation:
First, to find the mean of a set of numbers you need to add up all of the numbers and divide that by the total amount of numbers. In this case that makes this equation, [tex]\frac{3+3+4+8+9+10+12}{7}[/tex], which is [tex]\frac{49}{7}[/tex], which is 7.
To find a median you need to find the middle number. A handy trick I use for this is to place my fingers on the first and last number, and then move them towards the middle, at the same time by one number until there is just one number left in the middle. If there are no numbers left after doing this, meaning there are an even amount of numbers given, the median is the mean of the last two numbers that were covered. In this case, this is not necessary, so the median is 8.
The range is the difference between the maximum and minimum of a data set. In this case that would give you the equation Range=12-3, which means the range is 9.
Finally, the mode is the number that occurs the most in a given data set. In this case the number that occurs the most is 3, which occurs twice compared to every other number which only occurs once.
Hey there!
‘‘Find the mean median range and mode for 3, 3, 4, 8, 9, 10, and 12’’
• Mean is known as your AVERAGE number. You have to ADD all of your NUMBERS the DIVIDE it by the TOTAL numbers in your given set
• We have the total of SEVEN numbers in your set
“3 + 3 + 4 + 8 + 9 + 10 + 12 / 7”
6 + 4 + 8 + 9 + 10 + 12/7
10 + 8 + 9 + 10 + 12/7
18 + 9 + 10 + 12/7
27 + 10 + 12/
37 + 12/7
49/7 = 7
Answer: Mean = 7 ✔️
• Median is the number you see in the center (the middle) of the problem. You can solve for this by putting your numbers from least to greatest
• If you have an ODD number in your given set then your middle number will be the single number)
• If you have an EVEN number then you have to average your TWO middle number
“ 3, 3, 4, 8, 9, 10, 12”
• you still have 3 on both sides of your 8 (3 is an ODD number, so we have to let it be be a single number)
Answer: mean = 8 ✔️
• Mode is your number than you see repeated OR more than once
• We “3” repeated so it is your Mode
Answer: Mode = 3 ✔️
Answers ⬇️
• Mean: 7 ☑️
• Median: 8 ☑️
• Mode: 3 ☑️

Denise has $4.25 and needs to buy school supplies. She has a package of pencils that costs $1.75, a notebook that costs $1 and some erasers (x) that costs $0.25 each. At most, how many erasers can denise buy?
Answer:
6 erasers
Step-by-step explanation:
The pencils and the notebook together cost $2.75, from there you can calculate how many erasers.
1 eraser would bring the total to $3, therefore Denise can buy $1.25 more of erasers which is 5. 3 + 1.25 is $4.25. therefore Denise can buy 6 erasers
Answer:
he can buy 6 erasers
Step-by-step explanation:
because if you add 1.75 plus one and add 0.25 ....6 times it will equal 4.25 i hope this was helpful

Answer:
Its 3
Step-by-step explanation:
If we know that d is 10 we can substitute d for 10 thus giving us 10 - 7 which is 3
We are given,
d - 7 .....[eqⁿ (i)]and we are also given the value of d :
d = 10Now, just put the value of d = 10 in eqⁿ (i) we get :
10 - 73Hence your final answer is 3.Please hurry. I will give brainliest. :)

17 apples and 12 oranges cost $10.44. 3 apples and 4 oranges cost $2.84. How much does 1 orange cost?
Answer:
0.48$
Step-by-step explanation:
Cost of 1 Apple = A
Cost of 1 Orange = O
Six apples and three oranges cost $3.36 equivalent to:
6A + 3O = 3.36 (1st equation).
Two apples and five oranges cost $3.04 equivalent to:
2A + 5O = 3.04 (2nd equation).
Now we have to solve the 2 equations with 2 uknowns (the cost of 1 Apple = A, and the cost of 1 Orange = O).
6A + 3O = 3.36 (Equation 1)
2A + 5O = 3.04 (Equation 2), multiplying this equation by 3 we get:
6A + 3O = 3.36 (Equation 1)
6A + 15O = 9.12 (Equation 2), Now equation 2 minus equation 1 we get:
6A-6A +15O -3O = 9.12-3.36 equivalent to:
12O = 5.76 => O = 5.76/12 = 0.48 ( the cost of one Orange is 0.48$)
Go back to equation 1 and solve for the cost of 1 apple:
6A + 3x0.48 = 3.36 =>
6A + 1.44 = 3.36 =>
6A = 1.92 =>
A = 1.92/6 = 0.32 ( the cost of one apple is 0.32$)
Summary: The cost of one apple is 0.32$ and the cost of one orange is 0.48$.
for every 6 white roses, there are 8 pink roses. If the floral arrangement is proportional then how many pink roses are in a arrangement with 10 white roses
Answer:
13.33 pink roses
Step-by-step explanation:
We are told the floral arrangements are proportional , hence:
6 white roses = 8 pink roses
10 white roses = x
Cross Multiply
6 white roses × x = 10 white rose × 8 pink roses
x = 10 white roses × 8 pink roses/6 white roses
x = 13.333333333 pink roses
x ≈ 13.33 pink roses

I walk each day to school. By what percentage would I need to increase my usual average speed in order for the journey to take 20% less time than usual? C:
Answer:
25%
Step-by-step explanation:
Let v, t be the current average speed and the time taken to reach the school respectively.
As distance = speed x time, so,
distance, d=vt...(i)
Let V be the new average speed in order to to take 20% less time than t.
So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t
As distance is constant, so
d= V(0.8t)= 0.8Vt
hBy using equation (i), we have
0.8Vt = vt
0.8 V = v
V= v/0.8=1.25v
Therefore, the percentage increase in the average speed = [tex]\frac{V-v}{v}\times 100[/tex]
[tex]=\frac{1.25v-v}{v}\times 100[/tex]
=25%
Hence, the percentage increase in the average speed is 25%.
