There are five boys and five girls in a class. The teacher randomly selects three different students to answer questions. The first student is a girl, the second student is a boy, and the third student is a girl. Find the probability of this occuring.
Answer:
5/10
Step-by-step explanation:
for every girl picked a boy is also picked. There are 10 kids so it's a 50% chance it happens
Answer:
50%
Step-by-step explanation:
5/10
*simplify*
1/2
*divide 1 by 2*
0.5
*multiply by 100, or move the decimal twice*
0.5 ---> 5. ---> 50.
50. = 50

1/2bh is used to find the area for a triangle
what is the mid point of (27,3) and (18,-1)
Answer:
(22.5 , 1)
Step-by-step explanation:
Midpoint formula= [tex]\frac{x^1+x^{2} }{2} +\frac{y^{1} +2^{2} }{2} =Midpoint[/tex]
[tex]\frac{27+18}{2}[/tex]=22.5
3+-1=2
2/2=1
So, midpoint is (22.5 , 1)
You can also graph it out and use Pythagorean theorem but that would overcomplicate the problem.

Answer:
16
Step-by-step explanation:
(x + 4)(x + 4) = x² + 8x + 16
Referring to the figure, find the area of the
trapezoid shown.
The shape is 2 triangles. Find the area of each one and add them together.
1/2 x 6 x 10 = 30
1/2 x 10 x 12 = 60
30 + 60 = 90
Area = 90 square inches
Area of Trapezoid = ½ (a + b) h
= ½ (12 + 6) 10
= ½ × 18 × 10
= 1 × 9 × 10
= 9 × 10
= 90 in.²
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄12=-4(-6x-3) please help
Step-by-step explanation:
12=-4(-6x-3)
when minus is multiplied by minus then the result is plus,
12=24x+12
Now, subtract 12 from both sides,
12-12=24x+12-12
0=24x
Now, divide both sides by 24
0/24=24x/24
0=x
Answer and Step-by-step explanation:
First, distribute the negative 4 onto the negative 6x and negative 3.
12 = 24x + 12
Subtract 12 from both sides of the equation.
0 = 24x
Divide both sides of the equation by 24.
x = 0
To check our answer:
-4(-6(0) - 3) = 12
-4(0 - 3) = 12
-4(-3) = 12
12 = 12 ✓
So, x is equal to 0.

Quadrilateral ABCD with parallel sides AB and
CD is shown below.
Quadrilateral RSTU is the image of quadrilateral ABCD after a transformation. Which statement is true?
B
If quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides RS and TU
are not necessarily parallel.
If quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides AB and RS
must be parallel or on the same line.
D
If quadrilateral ABCD is translated to form quadrilateral RSTU, then sides AB and RS are not
necessarily parallel or on the same line.
If quadrilateral ABCD is reflected, rotated, or translated to form quadrilateral RSTU, then sides
RS and T'U must be parallel.
Answer:
Option DStep-by-step explanation:
The rotation or reflection will change the direction of the image but the translation will leave the corresponding sides parallel.
Now the answer choices:
AIf quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides RS and TU are not necessarily parallel.
Incorrect. Since RS and TU are parallel sides of same figure, they will remain parallel regardless the mentioned transformation. BIf quadrilateral ABCD is reflected or rotated to form quadrilateral RSTU, then sides AB and RS must be parallel or on the same line.
Incorrect. Since AB and RS are corresponding sides of the figures, the rotation will result in different angle between those sides. CIf quadrilateral ABCD is translated to form quadrilateral RSTU, then sides AB and RS are not necessarily parallel or on the same line.
Incorrect. Since it is just a translation, the corresponding sides will remain parallel. DIf quadrilateral ABCD is reflected, rotated, or translated to form quadrilateral RSTU, then sides RS and T'U must be parallel.
Correct. Since RS and TU are parallel sides of the same figure, they must remain as is regardless the reflection, rotation or translation.Solve the inequality for x and identify the graph of its solution.
|x+1|>2
Choose the answer that gives both the correct solution and the correct graph.
Answer:
D
Step-by-step explanation:
|x+1|>2
-2>x+1>2
-3>x>1
Option D is correct that is the solution of the inequality |x+1|>2 is x<-3 or x<1.
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
What is a solution of an inequality?Solution of an inequality is a value that makes the inequality true.
According to the given question
We have an inequality |x + 1|>2.
The solution set of the above inequality is given by
[tex]|x + 1| > 2[/tex]
⇒ [tex]-2 > x+1 > 2[/tex]
⇒ [tex]-2-1 > x > 2-1[/tex]
⇒ [tex]-3 > x > 1[/tex]
⇒ [tex]x < -3[/tex] or [tex]x < 1[/tex]
Hence, option D is correct that is the solution of the inequality |x+1|>2 is x<-3 or x<1.

A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 21. Find the number
Answer:
The number is 5
BRAINLIEST, PLEASE!
Step-by-step explanation:
8x + 2 = 2(21)
8x + 2 = 42
8x = 40
x = 5
In the expression, the value of number is 5.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We can to given that;
The algebraic expression is,
''A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 21.''
Now,
Let a number = x
Hence, We can formulate;
⇒ x × 8 + 2 = 2 × 21
⇒ 8x + 2 = 42
Subtract 2 both side,
⇒ 8x + 2 - 2 = 42 - 2
⇒ 8x = 40
Divide by 8;
⇒ x = 5
Thus, The value of number = 5

What is the answer and method for this equation?
Answer:
X = 15/16
Step-by-step explanation:
2(4-8x) + 6 = -1
8 - 16x + 6 = -1
14 - 16x = -1
-16x = -1 -14
-16x = -15
X = 15/16
Answer:
[tex]2(4 - 8x) + 6 = - 1 \\ 8 - 16x + 6 = - 1 \\ - 16x = - 1 - 6 - 8 \\ - 16x = -15 \\ 16x = 15 \\ \boxed{x = \frac{15}{16} }[/tex]
x=15/16 is the right answer.A circle is inscribed with 3 lines. Point x is at the center of the circle. A vertical line goes through point x to point z on the edge of the circle. A horizontal line goes through point x to point y on the edge of the circle. A diagonal line goes through point x to point w on the edge of the circle.

The cost of bowling is $5 per player for shoe rentals and $45 per hour to book a
lane. Suppose a group of f friends go bowling for h hours. Write an expression for
the total cost for the group of friends to go bowling.
Writing an expression consists of combining two or more variables, symbols, or numbers, with one or more mathematical operators to form a mathematical sentence that is based on a specific context
The expression for the total cost for bowling is 45·h + 5·f
The reason the above expression is correct is as follows:
The given parameters are;
The cost of shoe rentals for bowling per player = $5
The cost to book a lane per hour = $45
The number of people in the group of friends = f
The number of hours the friends go bowling = h
Required:
To write an expression for the total cost for the group of friends to go bowling
Solution:
Let the number of lanes the friends book= 1
The total cost, C, is the cost to book one lane at $45 per hour for h hours, plus the cost for the f number of friends to rent one shoe each at $5 per player (person)
Mathematically, C = 45·h + 5·f
The expression for the total cost for the group of friends to go bowling, is therefore;
45·h + 5·f

Express the formula d = rt in terms of the time, t. Use your formula to find the time when the distance is 40 and the rate is 8.
A)t= 4; 1 = 5
B)t= ; t = 0.2
C)t = dr; t = 320
D)t = d-r; t = 32
Answer:
t = d/r; t = 5
Step-by-step explanation:
Hi there!
1) Isolate t
d = rt
Divide both sides by r
d/r = rt/r
d/r = t
t = d/r
2) Solve for t when distance is 40 and the rate is 8
t = d/r
Replace d with 40 and rate with 8
t = 40/8
t = 5
