Terms is each part of an algebraic expression separated by a plus or minus sign.
As 2(5x +2y ) , 3x , 6y2(5x+2y),3x,6y and 1010 .
Factor is a product of two or more numbers, algebraic variables or algebraic expressions . 2(5x +2y )2(5x+2y) has two factors 22 and (5x +2y )(5x+2y) .
3x3x has two factors 33 and xx .
6y6y has two factors 66 and yy .
-10−10 has one factors
Coefficient is the numerical factor of a term that contains a variable.
2(5x +2y ) the factor is 22 .
3x3x the factor is 33 .
6x6x the factor is 66 .
-10−10 the factor is -10−10 .
Variable is a symbol, usually a letter, used to represent a number.
As xx and yy
Constant is a term without a variable.
As -10−10 .
Solve for t. Express your answer in simplest and exact form.
[tex]z=q_{1}t+t\frac{1}{2}ht^{2}[/tex]
Answer:
t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))
Step-by-step explanation:
Solve for t:
z = (h t^2)/2 + t q_1
z = (h t^2)/2 + t q_1 is equivalent to (h t^2)/2 + t q_1 = z:
(h t^2)/2 + t q_1 = z
Divide both sides by h/2:
t^2 + (2 t q_1)/h = (2 z)/h
Add q_1^2/h^2 to both sides:
t^2 + (2 t q_1)/h + q_1^2/h^2 = (2 z)/h + q_1^2/h^2
Write the left hand side as a square:
(t + q_1/h)^2 = (2 z)/h + q_1^2/h^2
Take the square root of both sides:
t + q_1/h = sqrt((2 z)/h + q_1^2/h^2) or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)
Subtract q_1/h from both sides:
t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)
Subtract q_1/h from both sides:
Answer: t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))
a movie theater sold 48 child tickets the other 2 tickets it sold were adult tickets what is the ratio of the number of adult tickets to the numberbof child tickets
Answer:
1 to 24 or 1:24
Step-by-step explanation:
1.) First , divide 2 by 2
2.) divide 48 by 2
3.so, for every adult ticket, there were 24 child tickets
or 1:24
the width of rectangle is 2w, and the length is (w+5). the perimeter is 40 inches. what are the measurements of the rectangle?
Width = 2w , Length = w+5 , perimeter = 40
Perimeter of rectangle = 2 (Length + Width)
P= 2 (L + w)
40 = 2 [ (w+5) + (2w) ]
40 = 2 ( 3w+5)
40= 6w +10
6w= 40 – 10
6w= 30
w = 30/6
w = 5
Width = 2w = 2(5) = 10
Length = w + 5 = 5+5 = 10

the sum of two numbers is 36. find the numbers whose sum of their square is in minimum
Answer:
512 is the minimum sum of the squares, when both numbers are 16.
Step-by-step explanation:
Make the two numbers equal. 16² + 16² = 256 + 256 = 512
Make the two numbers as far away as possible. 32² + 0² = 1024 + 0 = 1024.
The two numbers are 18 and 18 and the sum of their squares is 648 which is the minimum
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first number be = x
Let the second number be = 36 - x
Now ,
The sum of two numbers = 36
So ,
For both the numbers to be in their minimum value , the number will be half the original number
So ,
2x = 36
Divide by two on both sides , we get
x = 18
So , the two numbers are 18 and 18
Now ,
The sum of the squares of numbers A should be minimum ,
So ,
A = 18² + 18²
A = 324 + 324
A = 648
Therefore , the sum of the squares of two numbers is 648
Hence , The two numbers are 18 and 18 and the sum of their squares is 648 which is the minimum

Objective; Translating points
A translation is when we moving figures and points. We can represent a transformation algebraically and geometrically.
Algebracially:
[tex](x + h)[/tex]
where h is the amount of units we move right or left
and
[tex](y + k)[/tex]
where k is the amount of units we move up or down
For 1. We are asked to translate the figure 3 units up and 7 units to the left.
7 units to the left is the same as subtracting 7 . from x valyes. and 3 units up is is same as adding 3 units to the y values, so subtract 7 from every x coovalues. and add 3 to every y value. is
Our new coordinates
E is (-5,3) F is (-2,4) G is (-3,5) H is (-5,5).
2. 6 units right and 8 units up is basically add 6 to every x value and add 8 to every y value.
So our new coordinates is
T' (1,3)
U' (4,3)
V'(4,5)
W'(1,5)

Step-by-step explanation:
BCD = 180- 100 = 80
the opposite angles of a parallelogram are of equal measure
SO DAB = X = 80
The sum of all parallelogram angles = 360
360 - 160 = 200
200 equals the measure of angle ADC + ABC
ABC = ADC
200 = 2ABC
ABC = 100
ADB = DBC = 30
Y = 100 - 30 = 70
another way to find y is using the rule that says that the sum of the triangle ADB angles = 180
180 = 80 + 30 + y
y = 70

A drawing class was assigned a final project where students had to choose one art medium and one subject. The teacher kept track of the types of projects submitted.
The probability that a student used chalk is 0.3, the probability that a student chose to draw a plant is 0.6, and the probability that a student used chalk and chose to draw a plant is 0.2.
What is the probability that a randomly chosen student used chalk or chose to draw a plant?
Using probability concepts, it is found that: 0.7 = 70% probability that a randomly chosen student used chalk or chose to draw a plant.
-----------------------------
I am going to treat the probabilities of these events as Venn probabilities, stating that:
Probability A: student used a chalk.Probability B: student chose to draw a plant.-----------------------------
0.3 probability of a student using a chalk, thus [tex]P(A) = 0.3[/tex]0.6 probability that the student chose to draw a plant, thus [tex]P(B) = 0.6[/tex]0.2 probability of both, thus [tex]P(A \cap B) = 0.2[/tex].-----------------------------
The probability of chalk or plant is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
From the bullet points:
[tex]P(A \cup B) = 0.3 + 0.6 - 0.2 = 0.7[/tex]
0.7 = 70% probability that a randomly chosen student used chalk or chose to draw a plant.

Use the mean formula to write an equation to estimate x , the number of students who attended the fourth meeting.
c. Solve the equation in part (b) to find the number of students who attended the fourth meeting.
answer gets brainliest
The required formula to find the number of students who attended the fourth meeting is 80 = 56 + x
Using the mean formula, the number of students who attended the fourth meeting is 24
Formula to obtain the mean :
Mean = ΣX/ n
X = number of students that attended each meeting
n = number of meetings
X = meeting 1 + meeting 2 + meeting 3 + meeting 4
n = 4
Mean = 20
Let number of students who attended 4th meeting = x
Mean = ΣX/ n
20 = (18 + 21 + 17 + x) / 4
80 = 56 + x
x = 80 - 56
x = 24
Hence, 24 students attended the fourth meeting.

Step-by-step explanation:
Sometimes, two similar or congruent objects may be regarded as having a different shape if a reflection is required to transform one into the other. For instance, the letters " b " and " d " are a reflection of each other, and hence they are congruent and similar, but in some contexts they are not regarded as having the same shape.
