Can the sum of two irrational numbers ever be a rational number? Can the quotient of two irrational numbers ever be a rational number
Answer:
Yes and yes
Step-by-step explanation:
Example:
√2, 1 + √2 and 1 - √2 are all irrational.
(1 + √2) + (1 - √2) = 2
The irrational numbers cancel out, leaving you with 1 + 1 = 2, which is rational.
For quotients, we'll use √2 again.
√2/√2 = 1
1 is rational

Sandi got 1/1/4 pounds of gummy worms if she left the store with 3 pounds of gunmys worms and skittles ,how many pounds of skittles did she get
Answer:
1 3/4 lbs of skittles
Step-by-step explanation:
Easy way: 3lbs - 1 1/4lbs = 1 3/4lbs
Complex way:
(I'm assuming "1/1/4" means "1 1/4")
This is simply ~Subtraction~
The total is 3lbs(t) and 1 1/4 of that 3lbs is gummy worms(g). What is left of the 3lbs is skittles(s).
So we need to know what added to 1 1/4 equals 3.
Equation: t= 1 1/4 + s
Equation: t= 1 1/4 + s
We can replace (t) with 3 because we know this variable.
1. 3= 1 1/4 + s
To isolate the variable (s) we need to subtract 1 1/4 on both sides of the equation
2. 3(- 1 1/4)= 1 1/4(- 1 1/4) + s
The right side cancels out = 0 and the left = 1 3/4
3. 1 3/4= s
Flip it around for the traditional view
4. s = 1 3/4
In word form: Skittles equal 1 3/4 (don't forget to add lbs or pounds back into the final answer)

A car is traveling 90 miles per hour. How fast is it traveling in miles per minute?
Answer: 1.5 miles per minute
Step-by-step explanation:
The ratio for the hours is 90 Miles : 60 Minutes
Since 1 hour is 60 minutes, then 1 minute is 1/60 of a hour.
So, 1/60 will be the constant.
[tex]\frac{90}{1/60}[/tex]=1.5

A rectangle has perimeter 70 cm and length 29 cm. What is its width?
Answer:
6 cm
Step-by-step explanation:
70=29+29+2x
70=58+2x
70-58=2x
12=2x
12/2=x
6=x
Check: 29+29+6+6=70
Answer:
6 centimeters.
Step-by-step explanation:
The equation to find perimeter is P=2L+2W. L is length and W is width.
70=2(29)+2W
70=58+2W
70-58=2W
12=2W
6=w

Answer:
RS = 43
Step-by-step explanation:
Since RT is the whole line, your total is 59. Since you have part of what RT is which is 16, subtract 16 from 59.
59 - 16 = 43
Find length
__
AB
A:-6
B: 8
To find the distance between those two points you would need to
do, -6 - (8), which is -14, and than take away the minus sign, and the length of AB is 14 units.
Answer:
14 = AB
Step-by-step explanation:
When finding length, absolute value is the way to go! So if A is -6 and b is 8, then we need to find the distance between them. You can physically count on a number line like I see you did, which would be -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8=14 numbers
or you can set up the expression---
| -6-8 |
which equals
| -14 |
or
14
because 14 is the same as | -14 |
Which is true when a negative number is subtracted from a positive number?
A. The difference is always zero.
B. The difference is always positive.
C. The difference is always negative,
D. The difference could be positive or negative
Answer:
D is the correct answer
Step-by-step explanation:
it honestly depends on what the numbers are
for example, 12 -6, you would get 6.
but if the question is something like 4 -8, you'd have -4
If a + b = 20 and ab = 75, find the value of a? + b2.
Answer:
a² + b² = 250
Step-by-step explanation:
Given
a + b = 20 ( square both sides )
(a + b)² = 20² , that is
a² + b² + 2ab = 400 ( substitute ab = 75 )
a² + b² + 2(75) = 400
a² + b² + 150 = 400 ( subtract 150 from both sides )
a² + b² = 250
These circles are:
A. concentric
B. none of these
C. tangent
D. congruent
These circles are tangent .
What is tangent of two circles?Two circles are tangent to each other if they have only one common point. Two circles that have two common points are said to intersect each other. Two circles can be externally tangent if the circles are situated outside one another and internally tangent if one of them is situated inside the other.
According to the question
These circles are :
A > Concentric
This option is incorrect because circle are concentric if and only if they have common center .
B> none of these
This option is incorrect .
C > Tangent
This option is correct as Two circles are tangent to each other if they have only one common point and in the figure there is only one common point between both circles .
D> Congruent
This option is incorrect as this two circles have different size but in congruent both circle should be same size which is not possible here.
Hence, These circles are tangent .

The midpoint of UV is (5, -11). The coordinates of one endpoint are U(3,5). Find the coordinates of endpoint V.
The coordinates of endpoint V is (7, -27) if one endpoint is U(3,5) and the midpoint of UV is (5, -11)
Midpoint of a line is a point that divides any line into two equal parts.
The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as:
[tex]M(X, Y)= (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )[/tex]
Given the following
midpoint of UV = (5, -11)
U = (3, 5)
Get the other coordinate x2 and y2
Based on the formula above:
[tex]X = \frac{x_1+x_2}{2}\\5=\frac{3+x_2}{2}\\10 = 3 + x_2\\x_2 = 10-3\\x_2 = 7[/tex]
Get the other coordinate x2
[tex]Y = \frac{y_1+y_2}{2}\\-11=\frac{5+y_2}{2}\\-22 = 5 + y_2\\y_2 = -22-5\\y_2 = -27[/tex]
This shows that the coordinates of endpoint V is (7, -27)

how would i write The difference of three times a number and 4 is -19 in a equation?
Hi! I'm happy to help!
To solve this, we first have to understand the terms and the way they arrange the equation.
First, we have the difference of ____and_____=. (the "is" after 4 refers to equals)
We will write this as:
_______-_______= ,because difference means subtraction.
For our first blank, we have 3 times a number. Because we do not know this number, we will use a variable.(n) 3 times a number is 3 multiplied by a number. We can just write 3n, because it represent multiplication.
3n-______=
Now, we see the part of the equation after the "and". We just see 4, so we can insert that here:
3n-4=
Now, we see what is shown after the "is".
We just have -19, so we can insert that here:
3n-4=-19
Now, let's solve (not sure if I need to):
To solve for n, we have to isolate it on one side of the equation. To do this, let's cancel out the -4 on the left side of the equation by adding 4 to both sides:
3n=-15
From here, we need to get rid of the 3 next to the n by dividing both sides by 3:
n=-5
So, we write it as 3n-4=-19, and n=-5.
I hope this was helpful, keep learning! :D
