Answer:
Rs 104z
Step-by-step explanation:
[tex]\frac{1}{4}[/tex] litres cost Rs 4z
1litre cost Rs 4z×4 =16z
[tex]6\frac{1}{2}[/tex]⇒[tex]\frac{13}{2}[/tex]⇒6.5 litres cost Rs 16z×6.5 =Rs 104z
Solve the following equation systems using the elimintation mathod
2y - x = 8
-3x + 2y = -12
original equation
[tex]2y-x=8\\-3x+2y=-12\\[/tex]
line up your terms
[tex]2y-x=8\\\\2y-3x=-12[/tex]
since they are both positive, subtract
[tex]2x=20[/tex]
solve for x
[tex]x=10[/tex]
substitute into one of the equations and solve for y
[tex]2y-(10)=8\\\\2y=18\\\\y=9[/tex]
verify
[tex]2(9)-(10)=8\\\\18-10=9\\\\8=8\\\\LS=RS[/tex]
[tex]-3(10)+2(9)=-12\\\\-30+18=-12\\\\-12=-12\\\\LS=RS[/tex]

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+70,0000 . What is the difference in the populations of the cities when t=4
Answer:
25,800
Step-by-step explanation:
Plug in 4 everytime you see T.
multiple-150 times 4 plus 50000 which gives you 49,400.
then multiple 50 times 4 and add 75000, giving you 75,200 then subtract 75,200 - 49,400 which you end up with 25,800.

How would you use the coordinate plane to determine the area of Figure 3 on the graph below?
To identify the area of the figure, the amount it occupies on the x-axis and on the y-axis must be identified, and finally it must be multiplied.
How to identify an Area with the Coordinate Plane?To identify the area of figure 3, its extension must first be identified on one of the axes, for example, the x-axis, where its extension is:
Extension of the figure on the x axis = 2 (since it goes from 7 to 9).Then its extension on the y-axis must be identified, which is:
Extension of the figure on the axis y = 5 (since it goes from 5 to 10)Finally, the two visualized extensions must be multiplied to obtain the area of the figure:
Figure area = Extension x * Extension yArea of the figure = 2 * 5Figure area = 10Units are not used as they are not specified in the drawing or information, but could be square inches or square feet.

PLSS HELPPP!!!!!! HURRYYY!!! THXXX!!!Kylie compared the price per pound of two types of apples at her grocery store. She used the equation y=0.85x to represent y, the total cost in dollars of x pounds of apple A. She entered into the table below the cost of some weights of apple B.
What is the difference in the price per pound between apple A and apple B?
A
$0.40
B
$0.85
C
$1.25
D
$2.10
Answer:
Choice A is the correct answer.
Step-by-step explanation:
We can compare the prices by taking one of the weight values from the table for apple B and plug it into the equation for apple A.
For example, let's take 4 from the table. The equation would look like this:
y = 0.85(4) = $3.40.
This is the price of 4 pounds of apple A. However, the price for 4 pounds of apple B is $5.00.
5.00 - 3.40 = $1.60. This is the difference in price between 4 pounds of apple A and 4 pounds of apple B. If we want to find the difference per 1 pound, just divide 1.60 by 4.
1.60 / 4 = $0.40.
Therefore, the answer is Choice A.

Please help 4 math pages with questions. 1 has all the circle graphs, and all the other 3 have each circle graphs question. Please help.
Answer:
Favorite chip Answers v
Step-by-step explanation:
1. How many were surveyed? 82+8+18+62=100
2. How many said Jalepeno was their favorite? 8/100 0r 2/25 or 8%
3. How many said BBQ was their favorite?62/100 or 31/50 or 62%
4. How would it effect your final answer if the percentages did not add up to 100%? This means that your percentages are wrong. In a circle graph the percentages always equal 100%!
5. Is it possible to determine a missing percentage in a circle graph? Yes, we can always assume the total percentage is 100 so you add your given percentages together and then subtract that total from 100 to find the missing percentage.
500 people are asked to name their favorite color. The results of this survey are shown in the pie chart below:
Each sector of the pie chart makes an angle at the center. For example, the yellow sector makes an 18-degree angle, since 18 degrees is 5% of 360 degrees.
Which sector makes an angle closest to 40 degrees (Your answer should be a color word.)
Answer:
Purple
Step-by-step explanation:
40° is one-ninth of 360°. As a percent, this is equal to
1/9 ∙ 100% = 11.111111111111111111111111111111111111111111111111...%
Of all the sectors in the pie chart, the one closest to 11.111111111111111111111111111111111111111111111111...% is purple, at 12%.
HELP PLEASEE and thank youuu Find and interpret the mean absolute deviation of the data. 94,86,95,99,88,90 The mean absolute deviation is____. The values differ from the mean by an average of_____.
Step-by-step explanation: First of all the first step to find the mean absolute deviation you need to add 94, 86, 95, 99, 88 and 90 and then divide 552 which is the result that you get when you add by 6 getting an answer of 92. Second you need to find the distance or deviation but remember put those signs of absolute value when you find the answer.
remember the rule of absolute value which is that all numbers are always positive.
94-92= |2|
86 - 92= |6|
95-92=|3|
99-92=|7|
88-92=|4|
90-92=|2|
The final steps are to find the mean of the results you get when you subtract the deviation.
2+6+3+7+4+2= 24/6=4 is the absolute deviation
The mean absolute deviation is 4. The values differ from the mean by an average of 4.

How I divide by negative?? I forgot completely
Answer:
I hope this helps. If I misunderstood the question let me know
Step-by-step explanation:
1. When dividing a negative by a negative, your answer would be positive.
2. When dividing a negative by a positive, your answer will be negative.
3. When dividing a positive by a negative,your answer will be negative.
Divide like you normally would, the result will be the same as positive-number-quotients, but the quotient will be negative.
Example:
10 ÷ -5
since 5 is the dividend, 5 goes into 10 two times but note that it's negative two because of the negative division logic.
