Answer:
If you multiply any irrational number by the rational number zero, the result will be zero, which is rational. Any other situation, however, of a rational times an irrational will be irrational.

Step-by-step explanation:
Two blueberry farms are similar in shape. The ratio of the side lengths of the farms is 4 : 5, and the smaller farm has a perimeter of 280 yards. The cost to dig a trench is $0.75 per yard. What is the cost to dig a trench around the larger blueberry farm?
Answer: $262.50
Step-by-step explanation:
The yards are sized in a ratio of 4:5.
Assuming the perimeter of both farms is x, the formula to calculate it will be;
[tex]\frac{4}{4 + 5} x = 280\\\\x = 280/\frac{4}{9} \\\\x = 630 yards[/tex]
The perimeter of the larger fence will therefore be;
= 630 - 280
= 350 yards
The cost to dig the trench will be;
= 350 * 0.75
= $262.50

a thrift shop kept a record of how much it spent on cds every year starting in 2008 which statement best describes the information given in the scatterplot
The cost of CDs has been decreasing for the past five years. The correct option is A.
What is regression analysis?Regression analysis is a group of statistical procedures used in statistical modeling to determine the relationships between a dependent variable and one or more independent variables.
A scatter plot is a particular kind of plot or mathematical diagram that displays values for typically two variables for a collection of data. It uses Cartesian coordinates. When the points are coded, a further variable can be seen.
In the given scatter plot it is observed that the vertical line is represented by the amount of the CDs and the horizontal line is represented by years.
The amount of CDs is decreasing with time on yearly basis therefore, the cost of CDs has been decreasing for the past five years.

Solve for x. x+2/3=−1/6
Answer:
-5/6
Step-by-step explanation:
[tex]x+\frac{2}{3} = \frac{-1}{6}[/tex]
By transposing 2/3 towards the RHS we get,
[tex]x=\frac{-1}{6} -\frac{2}{3}[/tex]
[tex]x=-\frac{1}{6} -\frac{2X2}{3X2} =-\frac{1}{6} -\frac{4}{6} =\frac{-5}{6}[/tex]
Hello! :)
First, Simplify both sides of the equation
x + 2/3= -1/6
Next, Subtract 2/3 from both sides
x + 2/3 - 2/3 = -1/6 - 2/3
x= -5/6 (ANSWER)
Hope this helped you!

Calculate the distance travelled by a bus in 2 hours which moves with the velocity of 22 meter per second
Answer:
The distance traveled by the bus is 158,400 meters.
Step-by-step explanation:
Velocity and Distance
The velocity of a body can be calculated with the formula:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where d is the distance traveled in a time t.
The bus travels by t=2 hours and has a velocity of 22 m/s. We need to solve the above equation for d as follows:
[tex]d=v.t[/tex]
We first need to convert the time to seconds. Recall there are 3,600 seconds in one hour, thus t = 2*3,600 = 7,200 sec.
Now we calculate the distance:
[tex]d=22 m/\not{s}*7,200\not{s}= 158,400\ m[/tex]
The distance traveled by the bus is 158,400 meters.

Solve by factoring and applying the zero product property:
x^2-11x+18=0
Answer:
x = 2, x = 9
Step-by-step explanation:
Given
x² - 11x + 18 = 0
Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)
The factors are - 2 and - 9, since
- 2 × - 9 = + 18 and - 2 - 9 = - 11 , thus
(x - 2)(x - 9) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 9 = 0 ⇒ x = 9

Answer:
95° and 85°
Step-by-step explanation:
Same-side interior angles between parallel lines are supplementary:
(9x +14) +(8x +13) = 180
17x = 153
x = 9
9x +14 = 81 +14 = 95
8x +13 = 72 +13 = 85
The two angle measures are 95° and 85°.

Answer:
1 slope= -5/1 point= 11
2slope= 4/1 point= -3
Step-by-step explanation:
How do I go about solving this.
We know that angle CBD is a right angle.
We also know that angle ABE is 180°.
Our unknown angle values are angle DBE and angle CBA.
angle CBD minus angle ABE will be 90°.
angle ABC plus angle DBE must equal 90°.
Solving for x:
(x+15)+(x)=90°
(x+15-15)+(x)=90°-15
(x)+(x)=75°
2x=75°
2x/2=75°/2
x=37.5°
Checking the work:
ABC=37.5°+15=52.5°
CBD=90°
DBE=37.5°
In conclusion, ABC plus CBD plus DBE equals 180°
Hope this helped!

Last month, a salesman earned $560 more than he did
this month. Total earnings for the two months were
$8,720. Find each month's earnings.
Answer:
Month 1:$4695 Month 2: 3575
Step-by-step explanation:
Divide by 2:4135 is the amount for both months at first, but wait
Subtract 560 from one of the months and add it to the other: Step 1:4135-560=3575 Step 2:4135+560=4695

A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape. How much more tape does the company need to tape the site?
Julie, a cafeteria manager, is making a large amount of chicken soup to serve for lunch tomorrow.
For every 2 cups of carrots she uses in the soup, she uses 3 cups of celery. If she uses 18 cups of
celery, how many cups of carrots did she use?
Answer:
12 cups
Step-by-step explanation:
Divide the given amount of celery, 18 cups, by the number of cups in the given ratio, 3 cups.
[tex]18/3=6[/tex]
This number is how many times the ratio Julie used. Use this number to multiply the ratio number of carrots, 2 cups
[tex]2*6=12[/tex]
Julie uses 12 cups of carrots in her chicken soup
[tex]\frac{12}{18}=\frac{2}{3}[/tex]

Judy is working at a retail store over summer break. A customer buys a $50 shirt that is on sale
for 20% off. Judy computes the discount, adds sales tax of 10%, and tells the customer how
much he owes. The customer insists that Judy first add the sales tax and then apply the discount.
He is convinced that this way he will save more money because the discount amount will be
larger.
Answer:
Same final price, no differenceStep-by-step explanation:
Way 1, final price
Apply discount and then apply tax
(50 - 20%) + 10% =50*0.8*1.1 = $44Way 2, final price
Apply tax and then apply discount
(50 + 10%) - 20% = 50*1.1*0.8 = $44As we see both ways reveal same final price so no difference
Answer:
It does not matter in which order the discount and tax are computed.
Step-by-step explanation:
Judy first takes 20% off which gives a new price of $50(0.8)=$40. She then adds the 10% sales tax for a final price of $40(1.1)=$44. The customer first adds 10% for a new price of $50(1.1)=$55. He then takes 20% off for a final price of $55(0.8)=$44.
The customer is right to say that the discount amount will be larger, it is $11 opposed to $10 with his method. But the additional $1 just gets subtracted from the tax amount that was added in the first step. So the final price is the same in both cases.
Henri bought a swim suit at a cost of $8. Which statements are true regarding the cost of the suit? Select three options.
If the selling price is marked up by 25 percent, the new price will be $10.
If the selling price is marked up by 40 percent, the new price will be $7.50.
If the selling price is marked up by 55 percent, the new price will be $5.50.
If the selling price is marked up by 70 percent, the new price will be $13.60.
If the selling price is marked up by 75 percent, the new price will be $14.
Answer:
If the selling price is marked up by 25 percent, the new price will be $10.
If the selling price is marked up by 70 percent, the new price will be $13.60.
If the selling price is marked up by 75 percent, the new price will be $14.
Step-by-step explanation:
8 divided by 4 is 2 so 25% is 8+2+= 10
8 divided by 4 is 2 so 75% is 8+(3 x 2)= 8+6= 14
Answer:
If the selling price is marked up by 25 percent, the new price will be $10.
If the selling price is marked up by 70 percent, the new price will be $13.60.
If the selling price is marked up by 75 percent, the new price will be $14.
Step-by-step explanation:
8 divided by 4 is 2 so 25% is 8+2+= 10
8 divided by 4 is 2 so 75% is 8+(3 x 2)= 8+6= 14
