Answers
The distance between the 2 points A(-1, 5) and B(4, 1) is √41.
What is the distance?Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.The length of the line connecting two places represents the distance between them. Subtracting the different coordinates will reveal the distance if the two points are on the same horizontal or vertical line.So, the diatence between A(-1, 5) and B(4, 1):
Formula: d=√((x2 – x1)² + (y2 – y1)²Now, calculate as follows:
d=√((x2 – x1)² + (y2 – y1)²d=√((4 – (-1))² + (1 – 5)²d=√(5)² + (-4)²d=√25 + 16d=√41Therefore, the distance between the 2 points A(-1, 5) and B(4, 1) is √41.

No. There are 120 sixth-grade students who prefer online magazines and 140 seventh-grade students who prefer online magazines, and both of these values are greater than 100. So, they cannot be compared as percentages crossed out.
What is a percentage?It is a branch of Mathematics. It is a number or ratio expressed in the form of a fraction. A percentage can be denoted by the symbol %. It is a dimensionless number and it does not have any unit of measurement. The percentage is mainly used in shopping malls for giving discounts on clothes to customers. And the percent is used in salary increments in the company. The percentage is a very easy concept to learn by students or any other person. Percentage plays a key role in our daily life.

It’s geometry
Answers
Answer:
Angle 1: 115 degrees
Angle 2: 72 degrees
Angle 3: 57 degrees
Angle 4: 18 degrees
Angle 5: 122 degrees
Step-by-step explanation:
Note: I won’t be finding the angles in order
Angle 3 plus 33 is a right angle which is 90 degrees
So we subtract
90-33=57
Angle 3: 57 degrees
Now angle 2 can be found because a triangle sum of all three angles is 180 degrees
We know 2 75 degrees and 33 so we can add them
75+33=108
Now subtract from 180
180-108=72
Angle 2 is 72 degrees
we can find angle 1 by first finding the missing angle next to it in the triangle
75+40=115
180-115=65
Now we can subtract 65 from 180 to find angle 1
180-65=115
Angle 1 is 115 degrees
Next to find angle 4 we have to find the other missing angle since we already know angle 3 is 57 degrees
The missing angle we just subtract 75 from 180 since the angles are next to each other on a flat plane
180-75=105
And now we add the 2 angles we know
105+57=162
Now subtract from 180
180-162=18
Angle 4 is 18 degrees
Now angle 4 and angle 5 plus 40 degrees is equal to 180 degrees
To find angle 5 we add 40 degrees and 18
40+18
58
Now subtract from 180
180-58
122
Angle 5 is 122 degrees

For x = 1,
y = 1/2

Jennifer Lopez met her 10 cousins at a family reunion. The number of male cousins (x) is 2 less than the number of female cousins (y). How many (male,female) cousins were there? (not including Jennifer)
Answers
Answer:
Explanation:
Given that Jennifer Lopez has 10 cousins
The number of male cousins is x
The number of female cousins is y
Since x is 2 less than y, we have:
x = y + 2 ...............................................................................(1)
The total number of cousins is 10, we have:
x + y = 10 ..............................................................................(2)
Substituting equation (1) in (2)
(y + 2) + y = 10
y + y + 2 = 10
2y + 2 = 10
Subtract 2 from both sides
2y = 10 - 2
2y = 8
Divide both sides by 2
y = 8/2 = 2
Substitute the value of y into (1)
x = 2
Ursula has a cylinder and a cone that have the same height and radius. Which ratio compares the volume of the cone to the volume of the cylinder? О 1 to 3 01 to 2 O 2 to 1 O 3 to 1
Answers
Answer
The ratio of the volume of a cone to that of a cylinder is 1 to 3
Explanation
The volume of a cone is given as
Volume of a cone = ⅓πr²h
The volume of a cylinder is given as
Volume of a cylinder = πr²h
The ratio of the volume of a cone to that of a cylinder is now
Volume of a cone : Volume of a cylinder
⅓πr²h : πr²h
Divide both sides by πr²h and we have
⅓ : 1

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
There are two figure is shown in figure.
Now,
In first figure;
The sum of all the interior angle in a triangle is 180°.
So, We can formulate;
⇒ (6x - 10)° + (2x + 20)° + (3x + 5)° = 180°
Solve for x as;
⇒ (6x - 10)° + (2x + 20)° + (3x + 5)° = 180°
⇒ 6x - 10 + 2x + 20 + 3x + 5 = 180°
⇒ 11x + 15 = 180
⇒ 11x = 180 - 15
⇒ 11x = 165
⇒ x = 15
Thus, The value of the variable x in first figure will be 15.
For second figure;
We can formulate by the corresponding angle of the parallel lines as;
⇒ x + 50 = 70
⇒ x = 70 - 50
⇒ x = 20
Thus, The value of the variable x in second figure will be 20.

A quadratic equation is an equation such that there is a quadratic polynomial.

Assume that the equation is y = ax² + bx + 1.
Putting x = -3 and y = 0 in y = ax² + bx + 1:
0 = a×(-3)² + b×(-3) + 1
9a - 3b + 1 = 0 ....(i)
Putting x = 2 and y = 10 in y = ax² + bx + 1:
10 = a×(2)² + b×(2) + 1
4a + 2b - 9 = 0 ....(ii)
Multiply 2 with (i) and 3 with (ii), then add them:
18a - 6b + 2 + 12a + 6b - 27 = 0
30a - 25 = 0
a = 5/6
Putting a = 5/6 in 9a - 3b + 1 = 0:
9×(5/6) - 3b + 1 = 0
15/2 - 3b + 1 = 0
17/2 = 3b
b = 17/6
