Answer:
-7/30
Step-by-step explanation:
You can use 30 as the common denominator.
7/10 = (7/10)(3/3) = 21/30
14/15 = (14/15)(2/2) = 28/30
Then the difference is ...
7/10 -14/15 = 21/30 -28/30
= (21-28)/30 = -7/30

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?
Answers
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

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?
Answers
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]

Answers
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)

Step-by-step explanation:
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.
Answers
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.

Solve by factoring and applying the zero product property:
x^2-11x+18=0
Answers
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

Calculate the distance travelled by a bus in 2 hours which moves with the velocity of 22 meter per second
Answers
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.
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?
Answers
This is because they are putting tape around the perimeter. To find the perimeter you add up each side.
This is shown like this
20+20+40+40=120meters.
But the question is asking how many more meters of tape does the company so we subtract the amount of tape they already which is 100meters from 120meters.
So it can be written like this
120m -100m = 20meters of tape
Answer: the company needs 20 more meters of tape.

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°.
