To answer this question you will use ratios. The information given gives us a part to part ratio of 1 part vinegar for every 3 parts oil.

Because the total amount of furniture polish is 30 ounces, we will need to write one part vinegar to three parts oil as a part to part to whole ratio.

Use this information then and create an equivalent ratio with a total of 30 ounces. See below.

1 vinegar (x7.5) = 7.5 ounces
3 oil. (X7.5). = 22.5 ounces
4 total (x7.5). = 30 ounces

You will need 7.5 ounces of vinegar and a 22.5 ounces of oil.

Home Depot wants to buy a new line of fertilizers. Manufacturer A offers a 22/19 chain discount. Manufacturer B offers a 25/14 c
Temka [501]

Answer: A is 36.82%. B is 35.5%

Step-by-step explanation: For manufacturer A 22/19 chian discount simply means 22% discount followed by 19% discount.

Therefore we have 100-22= 78 and 100-19=81.

The final price would be 0.78*0.81=0.6318

Therefore discount would be

1 - 0.6318=0.3682

Hence, percentage discount would be 0.3682*100%=36.82%.

For manufacturer B 25/14 chian discount means 25% discount followed by 14% discount. So we have 100-25=75% and 100-14= 86%

Final price would be 0.86*.75=0.645.

Discount= 1 - 0.645= 0.355.

Percentage discount would be 0.355*100%=35.5%.

A patio in the shape of a semicircle has a diameter of 21 ft.
nikklg [1K]
The answer is 173 ft²

The area of the patio (A) is half of the area of the circle (A1) with a diameter of 21 ft:
A = A1/2

The area of the circle with radius r is: 
A1 = π * r²
π = 3.14
We do not have the radius, but we know that it is a half of the diameter:
r = 21 ft / 2 = 10.5 ft

A1 = 3.14 * (10.5)² = 346.18 ft²

So, the area of the patio is:
A = A1/2
A = 346.18 ft² / 2
A = 173.09 ft² ≈ 173 ft²

Data set: <span>2, 10, 10, 11, 11, 12, 12, 12, 13, 14, 14
</span>
range: 14 - 2 = 12
median: 12
lower quartile = 10
interquartile range = 4

Data set w/o outlier 2: <span>10, 10, 11, 11, 12, 12, 12, 13, 14, 14

range: 14 - 10 = 4
median: 12
lower quartile: 10.5
interquartile range = 3.5

The value that change the most by removing the outlier is A.) THE RANGE.</span>
