Which inequality is represented by the given graph?
C) y ≤ -3x+6
D) y ≥ 3x+6
Answer: c, y ≤ -3x+6
Step-by-step explanation:
for example we could use a point on the graph such as (-2, 0)
now we would insert the numbers into the inequality:
y ≤ -3x+6
= 0 ≤ -3(-2) +6
= 0 ≤ 6+6
= 0 ≤ 12
which is true! therefore it is y ≤ -3x+6

A student is taking an exam with 40 questions on it.To pass the exam she needs to answer 70% of the questions correctly. Unfortunately she answered only 40% of the 15 questions correctly. What percent of the remaining 25 questions does she have to answer correctly to pass the exam?
The first step is to find out how question in total she is able to miss, while still passing.
We know that there are [tex]40\\[/tex] questions on the test and she must get [tex]70[/tex]% of the questions correct.
Let's calculate how many questions that is:
40 x 0.70
= 28.
Subtract
40 - 28
= 12.
She is able to get 12 answers incorrect.
Now we must find out how many questions she got wrong when she got 40% of the first 15 correct.
If she got 40% correct; She got 60% incorrect.
Let's do the math:
Multiply:
15 x 0.40
= 6
Subtract:
15 - 6
= 9
This means that she got 6 questions correct, and 9 questions incorrect.
With the total allotment of 12 incorrect answers allowed, she can only get 3 more questions wrong.
Now we must find the percentage of the remaining 25 questions she can get wrong.
She can only get 3 wrong and she must get 22 correct.
Multiply:
22 x 4
= 88.
This means that she has to get 88% of the remaining 25 questions correct.
Three times the age of Abel is four more than the age of Asare.In three years,the sum of their ages will be 30 years.Find their present ages
Answer:
Abel is 7 and Asare is 17 years old
Step-by-step explanation:
Let the age of Abel is x and age of Asare is y.
Three times the age of Abel is four more than the age of Asare:
3x = y + 4And
In three years, the sum of their ages will be 30 years:
x + 3 + y + 3 = 30We got two equations.
Simplify and solve by substitution:
y = 3x - 4x + y = 243x - 4 + x = 24 Substitute y4x - 4 = 244x = 28x = 7Find y:
17 + y = 24y = 7at a party 5/9 of the persons were men and the rest were women.if there was total 1260 persons find the number of women in the present
SOLUTION :
let total people in the party be x i.e. 1260
then , number of men = 5/9 of x
= 5/9 of 1260 = 5 × 140 = 700 men
now ,
number of women = Total person - (number of total men)
= ( 1260 - 700 ) women
= 560 women

One yellow daisy and two pink carnations tied with ribbon will be used for corsages at a Mother's Day banquet. Each corsage takes 6 inches of ribbon. The daises are $0.85 each, the carnations are $0.50 each, and the ribbon is $0.24 per foot. There will be 24 corsages. What is the total cost?
Answer:
$47.28
Step-by-step explanation:
The total cost is found by adding the costs of the components.
Component costThere is one daisy, at $0.85 each.
There are to carnations at $0.50 each, for a total of 2×$0.50 = $1.00.
The is 6 inches of ribbon. That amount is 1/2 foot, so its cost is ...
(1/2 ft)×$0.24/ft) = $0.12.
Total costThe total cost of the components of one corsage is ...
daisy cost + carnation cost + ribbon cost = $0.85 +1.00 +0.12 = $1.97
There are 24 corsages, so their total cost will be 24 times this amount, or ...
24 × $1.97 = $47.28
The total cost of the 24 corsages is $47.28. All the costs of the components required for making a corsage are added to get the total cost of the corsage.
How to calculate the total cost?Total cost is the sum of all the individual component costs.Consider a and b are the two components with a cost K of each. Then the total cost = aK + bKCalculation:It is given that,
The components and their costs:
The cost of each daise = $0.85
The cost of each carnation = $0.50
The cost of the ribbon per foot = $0.24 (1 foot = 12 inches)
The components for making one single corsage:
One yellow daisy + two pink carnations + 6 inches of ribbon = 1 corsage
Then, calculating the price for one single corsage,
1 × $0.85 + 2 × $0.50 + (1/2) × $0.24 = cost of 1 corsage
⇒ $0.85 + $1 + $0.12
⇒ $1.97
For 24 corsages, the total cost = 24 × $1.97 = $47.28
Therefore, the total cost of the 24 corsages is $47.28.

Case Study:
ABC factory produces 24,000 units. The cost sheet gives the following information:
Direct Materials Rs. 1,20,000
Direct Labour Rs. 84,000
Variable overheads Rs. 48,000
Semi variable overheads Rs. 28,000
Fixed overheads Rs. 80,000
Total Cost
Rs. 3,60,000
Presently the product is sold at Rs. 20 per unit.
The management proposes to increase production by 3,000 units for sales in the foreign market. It is estimated that semi-variable overheads wil
1,000. But the product will be sold at Rs. 14 per unit in the foreign market. However, no additional capital expenditure will be incurred.
O
Answer:
Current Cost = Rs 360000
24000 units sold at rs 20 per unit
Turnover = 24000 * 20 = Rs 480000
Present Profit = 480000 - 360000 = Rs 120000
Profit per unit = 120000/24000 = 5 rs per unit
cost increased for increasing 3000 Production
Direct Material cost increase = (120000/24000) * 3000 = Rs 15000
Direct Labour cost increase = (84000/24000) * 3000 = Rs 10500
Variable overhead increase = (48000/24000) * 3000 = Rs 6000
Semi variable cost increased = Rs 1000
Cost Increased = 15000 + 10500 + 6000 + 1000 = 32500
Price per unit = Rs 14
Turnover from 3000 units = 14 * 3000 = Rs 42000
Proposed Profit from 3000 units = 42000 -32500 = Rs 9500
Proposed Profit per unit = 9500/3000 = Rs 3.17
Decision Depends upon management as Profit is there in a new market but per unit profit is lesser than current profit

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the length of the pen and x represent the width of the pen.
Hence:
Perimeter = x + y + x + y + x + x + x = 2y + 5x
2y + 5x = 3380
y = (3380 - 5x)/2 (2)
Area (A) = xy
A = x * (3380 - 5x)/2
A = (3380x - 5x²)/2
The maximum area is at A' = 0, hence:
A' = (1/2)(3380 - 10x)
0 = (1/2)(3380 - 10x)
10x = 3380
x = 338 ft.
2y + 5(338) = 3380
y = 845 ft.
