Explain why the product of a non-0 rational number and an irrational number is irrational?
Answer:
An irrational number is a number that can not be written as the quotient of two integer numbers.
Then if we have:
A = a rational number
B = a irrational number.
Then we can write:
A = x/y
Then the product of A and B can be written as:
A*B = (x/y)*B
Now, let's assume that this product is a rational number, then the product can be written as the quotient between two integer numbers.
(x/y)*B = (m/n)
If we isolate B, we get:
B = (m/n)*(y/x)
We can rewrite this as:
B = (m*y)/(n*x)
Where m, n, y, and x are integer numbers, then:
m*y is an integer
n*x is an integer.
Then B can be written as the quotient of two integer numbers, but this contradicts the initial hypothesis where we assumed that B was an irrational number.
Then the product of an irrational number and a rational number different than zero is always an irrational number.
We need to add the fact that the rational number is different than zero because if:
B is an irrational number
And we multiply it by zero, we get:
B*0 = 0
Then the product of an irrational number and zero is zero, which is a rational number.

What is the surface area
Answer:
red) area = 59.2 km²
Step-by-step explanation:
area of bottom 4 x 4 = 16
area of 4 sides = 4 (1/2)(4)(5.4) = 43.2
16 + 432 = 59.2 km²
Answer:
Step-by-step explanation:
lateral area = 2(base)(slant height) = 2·4·2 = 16 km²
base area = base² = 4² = 16 km²
surface area = 16 + 16 = 32 km²
There are two numbers. The larger number is five more than the smaller
number. Three times the smaller number increased by the larger number
equals 147. Find the two numbers.
please help!!!! im in a test!!!!!!!!
Answer:
35.5 + 40.5
Step-by-step explanation:
smaller number = x
large number = x +5
3x + x +5 = 147
4 x +5 = 147
4x = 142
x = 35.5
x +5 = 40.5

Apply the distributive property to factor out the greatest common factor.
Answer: 4(2x - 5)
Step-by-step explanation:
factors of 8 : (2, 2), 2
20 : (2, 2), 5
Therefore the GCF is 2*2 = 4
8x/4 = 2x and -20/4 = -5
4(2x - 5) = 8x - 20
A home was purchased in 1985 for $125,000. If the value of the home increased 2.5% each year, what would be the value of the house by 2025? Round to the nearest whole number.
Answer: $335,633
Step-by-step explanation:
First find the number of years difference:
= 2025 - 1985
= 40 years
Use the compound interest formula to find the answer:
= Value * ( 1 + rate) ^ no. of years
= 125,000 * ( 1 + 2.5%)⁴⁰
= $335,633

Jessica sold girl scout cokies she sold 26 boxes.How many cases of 12 plus extra boxes does she need.
Answer:
Jessica needs 2 cases of 12 girls scout cookies plus 2 extra boxes
Step-by-step explanation:
Number of boxes sold = 26
Cases of 12 plus extra boxes needed
Number of cases of 12 needed :
Number of boxes sold / 12
= 26 /12
= 2 remainder 2
Hence, Jessica needs 2 cases of 12 girls scout cookies plus 2 extra boxes
A college dorm refrigerator measures 18.5 cm by 32 cm 12.2 cm. What is the volume of the collage dorm refrigerator
Answer:
722.24 cm
Step-by-step explanation:
The volume formula is L X W X H = V so using that information we can do 18.5 times 32 times 12.2 which gives us 722.24 cm.
Rapid Rental Car charges a $55 rental fee, $20 for gas, and $0.65 per mile driven. For the same car, Capital Cars charges $55 for rental and gas and $0.75 per mile.
Answer:
200 miles
Step-by-step explanation:
Given data
Rapid Rental Car
charges a $55 rental fee
$20 for gas, and
$0.65 per mile driven
let the number of miles be x, the total charges y
y=55+20+0.65x
y= 75+0.65x----------1
Capital Cars
charges $55 for rental and gas and
$0.75 per mile.
let the number of miles be x, the total charges y
y=55+0.75x
y= 55+0.75x----------2
Required
The number of miles driven before the two Rental companies charge the same amount
equate 1 and 2
75+0.65x= 55+0.75x
collect like terms
75-55= 0.75x-0.65x
20= 0.1x
x= 20/0.1
x= 200miles
Hence the distance will be 200 miles for the charges to be the same

2 1/4 times 2 1/2
SHOW YOUR WORK!!!
Answer:
45/8 or 5 5/8
Step-by-step explanation:
2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8. you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.
Answer:
45/8 or 5 5/8
Step-by-step explanation:
When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.
Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.
Numerators: 9 x 5 = 45
Denominators: 4 x 2 = 8
So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.

-12x + 4y- 6y + 10x - 25 5x - 2(x - 12)
Answer:
=−259x−2y+24
Step-by-step explanation:
Distribute:
=−12x+4y+−6y+10x+−255x+(−2)(x)+(−2)(−12)
=−12x+4y+−6y+10x+−255x+−2x+24
Combine Like Terms:
=−12x+4y+−6y+10x+−255x+−2x+24
=(−12x+10x+−255x+−2x)+(4y+−6y)+(24)
=−259x+−2y+24
Answer:
=−259x−2y+24

Answer:
67.9
Step-by-step explanation:
The polygon has 6 sides.
Sum if interior angles = (n-2)180
=(6-2)180
= 4 x 180
= 720
A + B + C + D + E + F = 720
x+40 + 2x-9 + 2x + 2x + x + x+78 = 720
9x + 109 = 720
9x = 720-109
9x = 611
x = 611/9
x = 67.9
