4.Find the length of the diagonal of a rectangle having dimensions 16 cm and 12 cm.
Answer:
20 cm
Step-by-step explanation:
So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm.
Answer:
20 cm
Step-by-step explanation:
Here's your solution
=> length of rectangle = 16 cm
=> width of rectangle = 12 cm
=> Diagonal of rectangle = √(l^2 + w^2 )
=> Diagonal = √(16^2 + 12^2)
=> Diagonal = √(256 + 144)
=>. Diagonal = √400
=> Diagonal = 20 cm

Quadrilateral EFGH is on a coordinate plane. Segment FG is on the line 3x − y = −2, and segment EH is on the 3x − y = −6. Which statement proves how segments FG and EH are related?
Answer:
the slope of both lines are the same.
Step-by-step explanation:
Given the following segment of the Quadrilateral EFGH on a coordinate Segment FG is on the line 3x − y = −2,
segment EH is on the 3x − y = −6.
To determine their relationship, we can find the slope of the lines
For line FG: 3x - y = -2
Rewrite in standard form y = mx+c
-y = -3x - 2
Multiply through by-1
y = 3x + 2
Compare
mx = 3x
m = 3
The slope of the line segment FG is 3
For line EH: 3x - y = -6
Rewrite in standard form y = mx+c
-y = -3x - 6
Multiply through by-1
y = 3x + 6
Compare
mx = 3x
m = 3
The slope of the line segment EH is 3
Hence the statement that proves their relationship is that the slope of both lines are the same.
The slope of the lines is the same, the line segments FG and EH are parallel to each other and are the opposite sides of the quadrilateral.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is constant.
The slope of the line segment FG can be found by comparing the equation with the equation of the line. Therefore,
y = mx + c
-2 = 3x - y
- 2 - 3x = -y
y = 3x + 2
Thus, the slope of the equation is 3.
The slope of the line segment EH can be found by comparing the equation with the equation of the line. Therefore,
y = mx + c
3x - y = -6
-y = 6 - 3x
y = 3x+6
Thus, the slope of the equation is 3.
Since the slope of the lines is the same, the line segments FG and EH are parallel to each other and are the opposite sides of the quadrilateral.

An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.
What is a polygon?A polygon is a closed figure made up of three or more line segments connected end to end.
A polygon in the plane has rotational symmetry when the figure is mapped onto itself by rotating between 0 and 360° about its center.
So, we need to find the number of symmetrical lines a regular polygon.
A regular polygon with a sides has n lines of symmetry and order of symmetry.
Then, let a be the number of symmetrical line lines
An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. What is the probability that a student who has a brother also has a sister?
Answer: 11
Students have both a brother and a sister
Step-by-step explanation:
I don't think probability should be used for this question because the answer is quite clear
So in a class of 25 students
5 students don't have a sibling
So 25-5=20
Total number of siblings=14+17=31 siblings in total
So 20 people have 31 siblings
31-20=11
So the answer should be 11
In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. The probability that a student who has a brother also has a sister is 11/25.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.
In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings.
So in a class of 25 students
5 students don't have a sibling
then, 25-5=20
Total number of siblings = 14+17
= 31 siblings in total
So, 20 people have 31 siblings
= 31 - 20
= 11
So, the probability that a student who has a brother also has a sister
= 11/ 25.

5x + 19.95 = 35
Solve x
Answer:
X = 3.01
Step-by-step explanation:
To solve for x, you first need to get x by itself. So you would minus 19.95 from both sides. Which would then be
5x = 15.05
Again x is not by itself so you would divide both sides by 5, the eqation would then be
x = 3.01
Which is the answer. If you want you can double check your work by putting the answer back in the eqaution.
5(3.01) + 19.95 = 35
If the statement is true that means you have the right answer
15.05 + 19.95 = 35
35 = 35
We are correct! Hope this helps with your question and how to do others like it.

FIND X AND PLUG IT IN
You basically put x+12+2x+3+90=180 and solve for x. Then when you find x plug it in x+12 to find a and 2x+3 to find c.
Answer:
angle A is 37°
angle C is 53°
Step-by-step explanation:
The angles x+12 and 2x+3 add to 90°, because there is already a right angle in the triangle and the total angles in a triangle add to 180°
x+12+2x+3=90
3x+15=90
3x=75
x=25
Knowing x=25°, we can substitute it back into angle A and C.
A: 25+12=37°
C: 2(25)+3=50+3=53°
