vincent sells potatoes. He doesn’t sell potatoes my weight or one at a time. he insists on selling them in pairs.his customer graham wants a potato that weighs exactly 200g. Vincent tells him I only have 3 potatoes left. HERe they are A,B and C. A and B together weigh 300g, A and C together weigh 500g, B and C together weigh 400g. You can have any pair of them. Which if any of the potatoes weighs 200g? Which pair of potatoes should graham buy?
By solving a system of equations we will see that the best pair to buy is A and C.
Finding the equations:Here we have 3 potatoes, A, B, and C. Let's use these variables to define the weight of each potato.
Then, from the given information, we know that:
A + C = 500g
B + C = 400g
A + B = 300g
Then we have a system of equations, to solve it, first we isolate one of the variables in one of the equations. I will isolate A on the first one:
A + C = 500g
A = 500g - C
Now we can replace that in the third equation, now we have:
B + C = 400g
500g - C + B = 300g
Now we do the same thing, this time I will isolate C.
C = 400g - B
Let's replace this on the other equation:
500g - (400g - B) + B = 300g
500g - 400g + 2*B = 300g
100g + 2*B = 300g
B = (300g - 100g)/2 = 100g
So potato B weighs 100g.
We can use that to find the weight of the other two:
C = 400g - B = 400g - 100g = 300g
A = 500g - 300g = 200g
What pair should Graham buy?He wants 200g of potato, so he should buy one pair that includes potato A, which weight exactly 200g. And to get the most of his money, he should buy the pair that contains potato A and that weighs more. So the best pair will be A and C.

In a video game, the chance of rain each day is always 30%. At the beginning of each day in the video game, the computer generates a random integer between 1 and 50. Explain how you could use this number to stimulate the weather in the video game.
Answer: See below
Step-by-step explanation:
30% * 50
= 30/100 * 50
= 15
Therefore, 30% of the integers between 1 and 50 are in the range 1 to 15
So the random integer generated is in this range, that is, less than or equal to 15, then the weather must be simulated to be rainy.
This would mean that the chance of rain on each day is 30% (if the computer generates the random number consistently)
The total cost of 7 shirts and 5 pairs of pants is $517. The total cost of a shirt and a pair of pants is $89. How much does a pair of pants cost?
Answer:
pair of pants = $53
Step-by-step explanation:
s = shirts
p = pair of pants
eq = equation
eq 1: 7s + 5p = 517
eq 2: s + p = 89
multiply the equation 2 by 7
eq 3: 7s + 7p = 623
negate equation 1 and add it to the eq 3
7s + 7p = 623
+ -7s - 5p = -517
2p = 106
p = 53

Trapezia ABCD and PQRS are similar.
Find the area shaded in green.
The area shaded in green is 864 cm²
Similar figures
Similar figures, corresponding angles are congruent and the sides are ratio of each other. Therefore,
AB / PQ = CD / RS
30 / 10 = 24 / RS
30RS = 240
RS = 240 / 30
RS = 8 cm
let find the height of trapezium PQRS.
AB / PQ = 36 / h
30 / 10 = 36 / h
30h = 360
h = 360 / 30
h = 12 cm
Therefore,
area of the green portion = area of ABCD - area of PQRS
Area of a trapeziumarea = 1 / 2(a + b)hTherefore,
area of ABCD = 1 / 2(24 + 30)36 = 1 / 2 (54)36 = 1944 / 2 = 972 cm²
area of PQRS = 1 / 2(10 + 8)12 = 1 / 2(18)12 = 216 / 2 = 108 cm²
Area of the green portion = 972 - 108 = 864 cm²

5. To rent a bicycle a bike shop charges a deposit plus an hourly rate, Jim can
determine how much he will have to pay for a rental lasting t hours by using the
expression 8t + 20. What does the coefficient 8 most likely represent?
a) time
b.) insurance
c.) hourly rate
d.) deposit
Answer:
c.) hourly rate
Step-by-step explanation:
The value the coefficient represents can often be learned from its units. The term 8t gives a value in currency units, since the expression 8t+20 is an amount that is to be paid. (We can only add like terms, so both 8t and 20 must have currency units.)
The value of t has units of hours, so the coefficient 8 must have units that are ...
8 currency units/hour
That is, multiplying by hours gives currency units.
In this context, a number with units of currency units per hour is most likely the hourly rate of the rental.

Simplify the expression
5+2\cdot\left(2x-3\right)>=3x+4
5+2\cdot2x+2\cdot-3>=3x+4
5+4x-6>=3x+4
4x+\left(5-6\right)>=3x+4

17) The measures of two sides of a triangle are (2x + 3y) and (5x – 2y). If the perimeter
of the triangle is (12x + 5y), what is the measure of the third side?
Answer:
5x +4y
Step-by-step explanation:
The perimeter of a triangle is the sum of side lengths. That fact can be used to find z, the length of the third side.
(2x +3y) +(5x -2y) +z = 12x +5y . . . . sum of sides is perimeter
z = (12x +5y) -(7x +y) . . . . . . . . . . . . subtract (7x+y) from both sides
z = 5x +4y . . . . . . . . . collect terms; the length of the third side
The third side of the triangle is (5x +4y).

The type of eruption is directly related to the type of magma that is feeding them.
True Or False
Answer:
True
Step-by-step explanation:
The reason why this is true is because it is totally related. In a Shield volcano, the eruption happens with very fast, less dense, and more magma than that which comes from the stratovolcano. In a stratovolcano, most of the things are just ash and toxic gases. So, that's why, the stratovolcano is also more dangerous.
So hence, your answer is True

elijah has three neighbors the sum of all the neighbors ages is 80 the second-oldest neighbor is 28 years old the difference between the ages of the oldest neighbor and the youngest neighbor is 30, what is the age of the youngest neighbor ?
Ans:
Step-by-step explanation:
Let the age of oldest neighbour be x
let the age of youngest neighbour be x-30
According to question,
x+28+x-30 = 80
or, 2x +28-30=80
or,2x+28=80+30
or, 2x=110-28
or, 2x=82
or, x=82/2 = 41
Therefore, The age of oldest neighbour is 41 years
& The age of youngest neighbour= x-30 = 41-30 = 11 years!
In this unit, you calculated the surface area of solid figures composed of polygons, such as rectangles and triangles. But imagine finding the surface area of a cylinder—a solid figure that has several curved surfaces. A cylinder is made up of two circular bases and a curved (lateral) surface in between. Develop a formula for finding the surface area of the outside of a cylinder based on what you know about the circumference of a circle and the areas of circles and rectangles. (Hint: Think about rolling a rectangular piece of paper into the shape of a cylinder.) Discuss your approach and why it works.
Answer:
The surface area of a cylinder is the surface area of rectangular piece of paper as you roll it into a cylinder
and the surface area of the base and top areas:
Assume that you had a rectangular piece of paper with the long side h, and short side w, let h be the height of the cylinder as you roll it, the surface area generated is the circumference of the circle with radius r multiplied by the height = 2 ¶ r h . The area of the top and bottom circular bases is 2 ¶ r2
The total surface area = 2 ¶ r h + 2 ¶ r2 = 2 ¶ r ( h+ r ) to express r in terms of w , w = 2 ¶ r the width of the rectangle equal to the circumference of the circle , then the total surface area = w ( h+ r )
but r = w / 2 ¶ , the surface area = w(h+w/ 2¶) = (wh+ w2/2¶)

Find the equation of a line parallel to y=4x−4 that contains the point (−2,0). Write the equation in slope-intercept form.
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

so we're really looking for the equation of a line whose slope is 4 and passes through (-2 , 0)
[tex](\stackrel{x_1}{-2}~,~\stackrel{y_1}{0})\qquad \qquad \stackrel{slope}{m}\implies 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{4}(x-\stackrel{x_1}{(-2)}) \\\\\\ y=4(x+2)\implies y=4x+8[/tex]
