The product of two rational numbers is irrational.
Answer:
The statement is false.
Step-by-step explanation:
Here we need to remember some things:
Integer numbers are closed under multiplication.
This means that for two integers a and b, the product a*b is also an integer.
A rational number is a number that can be written as the quotient of two integer numbers.
An irrational number is a number that can't be written as the quotient of two rational numbers.
Now let's see the statement:
"The product of two rational numbers is irrational."
The product of two rational numbers is written as:
[tex]\frac{a}{b} *\frac{c}{d}[/tex]
Where a, c, b, and d are integers.
We can rewrite that product as:
[tex]\frac{a*c}{b*d}[/tex]
Because of the first property, we know that a*c is an integer, and b*d is also an integer, so here we have a quotient of two integer numbers, so this is a rational number.
Then the product of two rational numbers is a rational number.
Then the statement is false.
What value of x makes the equation 3(x-6)-8x= -2+5(2x+1) true
Answer:
x= −7/5
Step-by-step explanation:
Step 1: Distribute and combine like terms
3(x−6)−8x=−2+5(2x+1)
(3)(x)+(3)(−6)+−8x=−2+(5)(2x)+(5)(1)(Distribute)
3x+−18+−8x=−2+10x+5
(3x+−8x)+(−18)=(10x)+(−2+5)(Combine Like Terms)
−5x+−18=10x+3
−5x−18=10x+3
Step 2: Subtract 10x from both sides.
−5x−18−10x=10x+3−10x
−15x−18=3
Step 3: Add 18 to both sides.
−15x−18+18=3+18
−15x=21
Step 4: Divide both sides by -15.

if U=π (r+h),find the value of "r" when U=16 whole 1 upon 2 and h=2
Answer:
r = 3 1/4
Step-by-step explanation:
Here, we want to find the value of r given the values
Firstly, we will write r as the subject of the formula
U = π ( r + h)
U/π = r + h
r = U/π - h
Now substitute;
U = 16 1/2 = 33/2
h = 2
π= 22/7
r = 33/2/22/7 - 2
r = (33/2 * 7/22) - 2
r = 21/4 - 2
r = (21-8)/4
r = 13/4 = 3 1/4
Carrie often asks friends to play Among Us at lunch. Of the 5 games they play, Carrie wins 2 games. Consider this data. If she plays 20 games, how many games should you expect Carrie to win?
Answer:
8
Step-by-step explanation:
2 is 40% of 5, so if we stay within this data, then she will win 40% of the next 20 games she plays. 40% of 20 is 8, so she will win 8 games out of 20

Answer:
C) y = 2x
Step-by-step explanation:
That's the only equation that if x = 0, y will = 0
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
A
y = x + 1 ← has a y- intercept of 1
B
y = x - 1 ← has a y-intercept of - 1
C
y = 2x ← has a y- intercept of 0
D
y = 2x + 2 ← has a y- intercept of 2
Thus y = 2x passes through the origin → C
There are 12 steps in the staircase. Plz don't do it for points!!! How do you get the answer 150? i am really struggling will mark brainliest.
The distance from point A to B is 1 foot.
Given,
There are 12 steps in the staircase.
We need to find the distance of the steps.
The distance is given by AB.
Feet is the plural form of the foot.
What is a Pythagorean theorem?It states that in a right-angle triangle the hypotenuse is equal to the squares of the other two sides.
If the hypotenuse is H and the other two sides are A and B.
H² = A² + B²
We have a figure,
Where it is in a right-angled triangle.
Two sides are given: 7.5 inches and 10 inches.
And hypotenuse = AB.
Applying the Pythagorean theorem.
7.5² + 10² = AB²
AB² = 56.25 + 100
AB² = 156.25
AB = [tex]\sqrt{156.25}[/tex]
AB = 12.5 inches
Now,
AB = 12.5 inches.
We need to convert it into feet.
12 inches =1 foot
Multiplying 12.5/12 on both sides.
12.5/12 x 12 inches = 12.5/12 x 1 feet
12.5 inches = 1.0416 feet
Rounding to the nearest tenth we get,
12.5 inches = 1 feet
AB = 1 feet
Thus the distance of the staircase from point A to B is 1 foot.

3. Consider this dilation Complete sentences
(a) is the image of the dilation a reduction or an enlargement of the original figure? Explain
(b) What is the scale factor? Explain
Answer
Answer:
a) A reduction
b) The scale factor is 1/2
Step-by-step explanation:
The vertices of the original figure, ABCD are;
A(-2, 4), B(4, 4), C(2, -2), and D(-4, -2)
The vertices of the image, A'B'C'D' are;
A'(-1, 2), B'(2, 2), C'(1, -1), and D'(-2, -1)
a) The length of the side AB = 4 - (-2) = 6 (Distance between points having the same 'x' or 'y' coordinates
The length of the side A'B' = 2 - (-1) = 3
The length of AB = 6 is larger than the length of A'B' = 3, therefore the image A'B'C'D' is a reduction of (is smaller) the figure ABCD
b) The scale factor = The ratio of the lengths corresponding sides of the image to the original figure;
∴ The scale factor =A'B'/AB = A'D'/AD = B'C'/BC = D'C'/DC
AD = √((-4 - (-2))² + (-2 - 4)²) = 2·√10
A'D' = √((-2 - (-1))² + (-1 - 2)²) = √10
A'D'/AD= √10/(2·√10) = 1/2
Therefore, given that the coordinates of the preimage are 2 × the coordinates of the image, we have;
The scale factor = A'B'/AB = B'C'/BC = D'C'/DC = A'D'/AD =1/2
The scale factor is 1/2, therefore, we multiply the dimensions of the original figure by 1/2 to get the dimensions of the image.
The scale factor = 1/2.
How can-9 4/5
be expressed as the sum of its integer and fractional parts?
The fraction -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5
Expressing How can-9 4/5 as the sum of its integer and fractional partsThe integer part of a mixed number is the whole number portion, while the fractional part is the remaining fraction.
In this case, the integer part of -9 4/5 is -9, and the fractional part is 4/5.
To express the mixed number as the sum of its integer and fractional parts, we simply add the integer and the fraction:
So, we have
-9 + 4/5
When evaluated, we get
-9 + 4/5 = -45/5 + 4/5 = -41/5
Therefore, -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5 = -41/5.

The Wilsons have triplets and another child who is 14 years old. The sum of the ages of their children is 38. How old are the triplets? Please give me the equation!! Correct answer will get brainliest
Answer:
Each age of the triplets should be 8 years old.
Step-by-step explanation:
38-14=24
24 divided by 3 = 8
Answer:
Triplets are 8 not sure on the equation but I think its y = 8x + 38.
Step-by-step explanation:
I'm assuming that all their ages together equal 38 therefore I would take,
38 - 14 = 24; this means that the triplets ages added together equal 24. Since triplets means 3 I will take,
24 dived 3 = 8.
I check my work by doing 14 + 8 + 8 + 8 = 38.
you asked for an equation I'm sure what you mean but I can try; I'm putting it into slope intercept form.
y = 8x + 38

A collar of Styrofoam is made to insulate a pipe. Find its volume. The large radius R is to the outer rim. The small radius r is to the edge of the insulation. Use pi ≈ 3.14 r=2 R=4 h=20
The volume of the pipe formula is given as:
Use pi ≈ 3.14 r=2 R=4 h=20
Volume =h × π (R² -r²)
Volume =20 × 3.14 × (4² - 2²) cubic units
Volume = 62.8 × ( 16 - 4) cubic units

5 divided by 3
Answer:
Start by setting it up with the divisor 3 on the left side and the dividend 105 on the right side like this:
3 ⟌ 1 0 5
Step 2:
The divisor (3) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:
0
3 ⟌ 1 0 5
Step 3:
Multiply the divisor by the result in the previous step (3 x 0 = 0) and write that answer below the dividend.
0
3 ⟌ 1 0 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
0
3 ⟌ 1 0 5
- 0
1
Step 5:
Move down the 2nd digit of the dividend (0) like this:
0
3 ⟌ 1 0 5
- 0
1 0
Step 6:
The divisor (3) goes into the bottom number (10), 3 time(s). Therefore, put 3 on top:
0 3
3 ⟌ 1 0 5
- 0
1 0
Step 7:
Multiply the divisor by the result in the previous step (3 x 3 = 9) and write that answer at the bottom:
0 3
3 ⟌ 1 0 5
- 0
1 0
9
Step 8:
Subtract the result in the previous step from the number written above it. (10 - 9 = 1) and write the answer at the bottom.
0 3
3 ⟌ 1 0 5
- 0
1 0
