Answer:
True
Step-by-step explanation:
If A/B and C/D are rational expression then
A/B*C/D
Or
A/B*C/D=A/C*B/D
It means that if A/B and C/D are rational expression then their product with each other will also be a rational expression.
A ladder 13m long leans against a wall such that the top of the ladder is 12 m from the ground.how far is the foot of the ladder from the wall
Answer:
5
Step-by-step explanation:
The pythagorean theorem
A^2+B^2=C^2
A^2 =12^2
b^2 is what you need to find
C^2= 13^2
so it's
144+B^2=169
-144 -144
B^2=25
square root of 25 is 5 which is the answer

Answer:
1) 43/40
2) 35/6
3) 43/40
4) -5/3
5) 1/6
Step-by-step explanation:
1) -1 4/5 = -(1*5 +4)/ 5= -9/5
or 1= 5/5 so -1 4/5= -( 5/5+ 4/5)=-9/5
-2 7/8= -(2*8+7)/8=-23/8
=> -9/5 - ( -23/8)= -9/5 + 23/8 = (( -9*8)+(23*5))/40= (-72+ 115)/40
= 43/40
2) 4 3/4= (4*4+3)/4= 19/4
-1 1/12= -(1*12+1)/12= -13/12
=> 19/4 - (-13/12)= 19/4 + 13/12 = ((19*3)+13)/12= (57+13)/12= 35/6
3) same like 1)
4) 3 1/3 = (3*3+1)/3= 10/3
=> 10/3 -5= (10- 3*5)/3= (10-15)/3= -5/3
5) -1/3 + 1/2= ((-1*2)+(1*3))/6 = (-2+3)/6= 1/6

To list the numbers from smallest to largest we need to determine the value of them in same/similar format
11 and 1 is in same format
The approximate value of [tex]\pi ^{2}[/tex] 9.8
the root of [tex]\sqrt{121}[/tex] = 11
the root of [tex]\sqrt{130}[/tex] is = 11.4 approximately

Amir stands on a balcony and throws a ball to his dog, who is at ground level.
The ball's height (in meters above the ground), xxx seconds after Amir threw it, is modeled by:
h(x)=-(x-2)^2+16h(x)=−(x−2)
2
+16h, left parenthesis, x, right parenthesis, equals, minus, left parenthesis, x, minus, 2, right parenthesis, squared, plus, 16
How many seconds after being thrown will the ball hit the ground?
Answer:
6 seconds
Step-by-step explanation:
h(x)=-(x-2)^2+16
We want h(x) to be 0 ( that is when the ball hits the ground)
0 = -(x-2)^2+16
Subtract 16 from each side
-16 = -(x-2)^2+16-16
-16 = -(x-2)^2
Divide by -1
16 = (x-2)^2
Take the square root of each side
sqrt(16) = sqrt((x-2)^2)
±4 = x-2
Add 2 to each side
2±4 = x-2+2
2±4 =x
2+4 = x 2-4 = x
6 =x -2 =x
Time cannot be negative so x=6
Answer:
X = 6

please help me out on this problem!
the main floor of an auditorium ranges from 6 feet below the stage
to 8 feet above the stage. the floor of the balcony ranges from 26 to 37 feet above the stage. write the range of the floor levels relative to the stage in interval notation and in set-builder notation.
This is a simple problem of ranges, we will find that the ranges for the main floor and the balcony are:
[-6ft, 8ft] or {x ∈ R | -6ft ≤ x ≤ 8ft}
[26ft, 37ft] or {x ∈ R | 26ft ≤ x ≤ 37ft}
respectively.
We know that:
The main floor of the auditorium ranges from 6ft below the stage to 8 feet above the stage.
The floor of the balcony ranges from 26 to 37 feet above the stage
The ranges relative to the stage will be, in interval notation, the interval that contains the two extremes of the range.
For the main floor, it goes from -6ft to 8ft (the first one is negative because is 6ft below the stage) then this interval will be: [-6ft, 8ft]
While in set-builder notation we want to specify that the variable must be a real number, so we start with: {x ∈ R
And we need to specify that x can go from -6ft to 8ft, then we add the restriction:
{x ∈ R | -6ft ≤ x ≤ 8ft}
Notice that we use a close interval here.
While for the balcony, the minimum is 26ft and the maximum is 37ft, then the interval will be [26ft, 37ft]
For the set-builder notation we will have:
{x ∈ R | 26ft ≤ x ≤ 37ft}

This is because when you simplify 6/30 to the lowest form, you get 1/5
Answer:
There are a lot of fraction that can be equal to the values given above. It can be as follows:
1/5 = 2/10, 3/15, 4/20, 5/25, 6/30, 7/35,8/40
4/7 = 8/14, 12/21, 16/28

Step-by-step explanation:
BC = CD
6x-16 = 4x+10
Subtract 4x from each side
6x-16-4x = 4x+10-4x
2x-16 = 10
Add 16 to each side
2x-16+16 = 10+26
2x = 26
