Use the distance formula to find the distance between the two points.
√[(x₂ - x₁)² + (y₂ - y₁)²]
√[(3 - -4)² + (3 - -2)²]
√[(7)² + (5)²]
√[(49) + (25)]
√74

Ellen has a bag with 3 red marbles and 2 blue marbles in it. She is going to randomly draw a marble from the bag 300 times, putting the marble back in the bag after each draw. 3 red marbles and 2 blue marbles What is the best prediction for the number of times that Ellen will draw a blue marble?
Answer:
120
Step-by-step explanation:
Blue marbles = 2
Red marbles = 3
Total marbles = 2 + 3 = 5
If a marble is drawn 300 times ;prediction for the number of times a blue marble will be drawn :
P(drawing a blue marble) = number of blue marbles / total number of marbles
= 2 /5 = 0.4
Predicted number of times blue is drawn in 300 selections :
300 * 0.4 = 120
Approximately 120 times

Answer:
[tex]x=\sqrt{41}[/tex]
Step-by-step explanation:
Pythagorean theorem: [tex]a^{2}+ b^{2}=c^{2}[/tex]
Answer:
Option B
Step-by-step explanation:
Pythagorean Theron is:
[tex]a^2+b^2=c^2\\\\\text{a and b - legs}\\\text{c - hypotenuse}[/tex]
We would be solving for 'c', or the hypotenuse.
[tex]4^2+5^2=c^2\\\\16+25=c^2\\\\41=c^2\\\\\boxed{\sqrt{41}, -\sqrt{41} =c}[/tex]
The correct answer should be option B.
Hope this helps.

The circumference of a circle is approximately 131.88 centimeters What is the area of the shaded region (6/10 of a circle)
Answer:
82.97cm^2
Step-by-step explanation:
Given data
Circumference= 131.88 centimeters
We want to find the area of 6/10 part of a circle
Firstly, let us find the area of the circle
We need to get the radius
C= 2πr
131.88= 2*3.142*r
131.88=6.284r
r= 131.88/6.284
r=20.98 cm
Area= πr^2
Area= 3.142*20.98^2
Area= 3.142*440.16
Area= 1382.98cm^2
Hence 6/10 of a 1382.98
=0.06*1382.98
=82.97cm^2
b. If C(a) is the cost in dollars to plant a acres of soybeans, what does C-1(35,000) represent?
9514 1404 393
Answer:
the number of acres planted for a cost of $35,000
Step-by-step explanation:
If the function C gives the dollar cost of planting a certain acreage, then the inverse function C^-1 gives the acreage planted for a given dollar cost.
C^-1(35000) gives the acreage planted for a cost of $35,000

The question goes like this:
a book has a hundred and twenty. I have read a quarter of the pages. How many pages do I have?
Answer:
You have 90 pages left.
Step-by-step explanation:
1/4 × 120 = 30 pages read
Therefore
120- 30
=90 pages left to read
Answer:
You read 30 pages of the book.
You have 90 pages left.
Step-by-step explanation:
120 total pages
⇒ 120 = 100%
[tex]\frac{1}{4}[/tex] pages have been read
⇒ [tex]\frac{1}{4}[/tex] = 25%
[tex]\frac{3}{4}[/tex] remaining
⇒ [tex]\frac{3}{4}[/tex] = 75%
120 x .25 = 30 pages read
120 x .75 = 90 pages unread
30 + 90 = 120

The volume of this cylinder is 175pi cubic units. What is the volume of a cone that has the same base area and the same height? Write your answer in terms of pi.
Answer: 58.33π units ³
Step-by-step explanation:
The volume of a cylinder = πr²h
The volume of a cone = 1/3πr²h
Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:
= 175π / 3
= 175/3π
= 58.33π units ³
The volume of the cone is 58.33π units ³
Answer:
183
Step-by-step explanation:
When multiplied by pi, it rounds out to 183.
In a class, there are twice more boys than girls. Six boys leave the class and six girls arrive ;
therefore, there are twice more girls than boys .
How many boys and girls were there at first ?
please show calculations steps plus this should be solved as a system
Answer:
Boys= 12
Girls= 6
Step-by-step explanation:
Let no: of girls be 'x'
No: of boys= 2x
boys after= 2x-6
girls after = x+6
according to the question,
2(2x-6)=x+6
4x-12=x+6
3x=18
x=6
No: of girls at first= 6
No: of boys at first=2*6=12
Julie says the most amount of time spent on homework is 1/2 times the least amount of time spent of homework. Is she correct? Explain
Answer:
Step-by-step explanation:
I believe this question is coming from a statistical data, which for whatever reasons is not present here. If Julie says the most amount of time spent, it meant that the time most time people spent on the homework. And if she says the least amount of time. This means that the least number of time people spent on the homework.
Then again, she says it is half times, this means that if 5 people spent the most amount of time in doing something, then 10 people must have spent the least amount of time doing the same exact thing.

write an equation in slope-intercept for the line that has a slope of 1/2 and goes through the point (4, 7)
Answer:
y = 1/2x + 5
Step-by-step explanation:
The formula for an equation is y = mx + b
m is the slope. It is given
y = 1/2x + b
b is the y-intercept
In this case, we must substitute to find the y-intercept
We are given coordinate pair (4,7)
Plug our pair in and we get => 7 = 1/2(4) + b
=> 7 = 2 + b
easily, we find b = 5
We get our equation: y = 1/2x + 5

The area of rectangular is 64m the length of the pool is 12 m less that the width .The situation can be represented by the equation x
Answer:
Width = 16 m
Length = 4 m
Step-by-step explanation:
The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x
Area of a rectangle = Length × Width
L = W - 12
Hence:
64 = (W - 12) × W
64 = W² - 12W
W² - 12W - 64 = 0
Factor using
(W + 4)(W - 16) = 0
Width = 16m
Length = W - 12
Length = 16 m - 12 m
= 4 m
What is the área of this figure? (I need the answer bc this Is due in 1 hr )
Answer: 353ft
Step-by-step explanation:
To work out what the area of this composite shape is, you would split it into two shapes; a square and a rectangle.
For the formula of the rectangle and square you would do base x height.
So,
For the square you do 13x13=169
For the rectangle you would do 23x8=184
Then to work out the total area of the two shapes you would add the two areas together.
169+184=353
