The correct answer is $15
Explanation:
The first step is to determine the total of oil that was used for the 5 batches. To find this, you just need to multiply the amount of oil used for one batch by the total batches.
1 cup of oil per batch x 5 batches = 5 cups of oil
This means, in the 5 batches the oil Dinesh used was 5 cups of oil. Additionally, you know the total of cups in the bottle of oil is 12 cups, and these 12 cups or total costs $36. Now to find what is the cost of the 5 cups use the rule of three and cross multiplication.
12 cups of oil = $36 1. Write the values
5 cups of oil = x
12 x = 180 2. Cross multiply this means 36x 5 and 12 multipy by x
x = 180 ÷ 12 3. Solve the equation
x= 15 - Cost for 5 cups used in the batches
Okay sorry but this question is actually a little simple if you think less
Answer:
an = -8 +3(n-1)
an = -11 +3n
f(n) = -11 +3n
Step-by-step explanation:
–8, –5, –2, 1, 4, ...
This is an arithmetic sequence.
We are increasing by 3 each time
-8 +3 = -5
-5+3 = -2
-2 +3 = 1
The common difference is 3
The formula for an arithmetic sequence is
an = a1 +d (n-1)
an = -8 +3(n-1)
an = -8 +3n -3
an = -11 +3n
The nth term is -11 +3n
f(n) = -11 +3n
So if OP is a segment joining center O to point P, the MN is touching the circle on point P so it would be line MN.
Answer:
1) $4400
2) $4400
Step-by-step explanation:
Let
X = price in first year
Y = price in 2nd year
Z = price in 3rd year
A = price in the end of 3rd year
Y = 1.1 X
Z = 0.8 Y
substitute Y into Z get Z = 0.88 X
A = 1.25 Z= 1.25(0.88X) = 1.1 X
1)
(125/100) Z = 22000
Z = 22000 x 100 / 125 = 17600
Z = 0.8Y
Y = Z/0.8 = 1.25Z
Amount of dollar decrease in 2nd year = Y - Z
= 1.25Z - Z = 0.25Z = 0.25 x 17600 = 4400 dollar
2)
Decrease in price over first 2 years = Increase in property in 3rd year - 2000
Hence, X - Z = (A-Z) - 2000
X - 0.8X = 1.1 X - 0.88 X - 2000
X - 0.88X - 1.1X + 088X = -2000
-0.1 X = -2000
0.1 X = 2000
X = 20000
Amount of dollar decrease during 2nd year = Y - Z = 1.1X - 0.88X = 0.22X
= (0.22) x (20000) = 4400 dollars
