At a concession stand, a pickle and two bags of chips costs a total of $3.25. Three pickles and four bags of chips costs a total of $7.25. To determine the cost of one pickle, Kevin is writing a system of equations. His first equation is shown: x + 2y = 3.25
Which of the following could be the second equation in his system of equations?
3x + 4y = 7.25
4x + 3y = 7.25
3x - 4y = 7.25
(3 + 4)x = 7.25
Answers
Answer:
p + 2c = 3.25 Start with these two equations
3p + 4c = 7.25
p = -2c + 3.25 Solve for one variable
3(-2c +3.25) + 4c = 7.25 Substitute
-6c + 9.75 + 4c = 7.25
-2c = -2
c = 1
p + 2(1) = 3.25 Substitute
p + 2 = 3.25
p = 1.25
A bag of chips costs $1
A pickle costs $1.25

Element X is a radioactive isotope such that every 30 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 100 grams, how long would it be until the mass of the sample reached 64 grams, to the nearest tenth of a year?
Answers
Answer:
19.3 years
Step-by-step explanation:
Given that the initial mass of a sample of Element X is 100 grams,
The formula is given as:
N(t) = No × (1/2) ^t/t½
Element X is a radioactive isotope such that every 30 years, its mass decreases by half.
N(t) = Mass after time (t)
No = Initial mass = 100 grams
t½ = Half life = 30 grams
N(t) = 100 × (1/2) ^t/30
How long would it be until the mass of the sample reached 64 grams, to the nearest tenth of a year?
This means we are to find the time
N(t) = 100 × (1/2) ^t/30
N(t) = 64 grams
64 = 100(1/2)^t/30
Divide both sides by 100
64/100 = 100(1/2)^t/30/100
0.64 = (1/2)^t/30
Take the Log of both sides
log 0.64 = log (1/2)^t/30
log 0.64 = t/30(1/2)
t = 19.315685693242 years
Approximately = 19.3 years

Find the area of this shape
Answers
Answer:
433 m²
Step-by-step explanation:
Find the side length of the square first.
Apply Pythagoras Theorem on 1 of the triangles on the right, to find its remaining side.
[tex] \sqrt{ {12}^{2} - {9.6}^{2} } [/tex]
=[tex] \sqrt{51.84} [/tex]
= 7.2 m
Therefore the side of the square is
7.2 ×2
= 14.4 m
The area of the square
= 14.4²
= 207.36 m²
You are able to find the area if of the 2 triangles.
(7.2 × 9.6)÷2 ×2
= 69.12 m²
The height of the pentagon
= 25.4 - 7.2
= 18.2 m
The area of the pentagon
= (10+7.2) × 18.2 ÷ 2
= 156.52 m²
Add up the areas of the 3 polygons.
The area of the shape
= 207.36 + 69.12 + 156.52
= 433 m²

The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 63 students, requires 5 chaperones, and costs $1,400 to rent. Each van can transport 9 students, requires 1 chaperone, and costs $100 to rent. Since there are 756 students in the senior class that may be eligible to go on the trip, the officers must plan to accommodate at least 756 students. Since only 70 parents have volunteered to serve as chaperones, the officers must plan to use at most 70 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation costs? What are the minimal transportation costs?
Answers
Number of buses needed = 7

please describe the difference between the slope and the y-intercept. Please also describe how we can use the slope and y-intercept to graph.
Answers
Answer:
The slope is basically the rate of change in which it describes how steep the line is. The y-intercept is a point in the graph in which a point crosses the y axis.
The slope and the y-intercept is connected with the formula y=mx+b, where b is the y intercept and mx is the slope. With this equation, you can graph by first putting your y-intercept (b) in the graph, remember that the y-intercept has x as 0, for example (0,4) or (0,12). After that, all you have to do to complete the line is to use the slope by plugging the x to the slope and adding the y-intercept.
Now you might have a little idea of what is the slope and y-intercept, and might still be confused on certain things, so ill give an example.
ex) you are given the formula y=2x+4 and you are asked to graph it
step 1) you take the b, which is 4 and put it in the graph, knowing the the point is (0,4) because b is the y-intercept, which means that x=0.
step 2) take a random x point on the xaxis and plug it in the formula, then you add the b (4), lets say x=2
so it will become 2(2) +4 = 6, so when x=2, y is 6.
Now you have found 2 points, (0,4) and (2,6), all you have to do is plug it in the graph.
The graph is drawn below.
If you have anymore questions, don't hesitate to message me.
Hope that answers your question, good luck in your test

A teacher is making worksheets for the next unit. He can create 3 worksheets in an hour and has 10 worksheets already created from the previous year. Which of the following lengths of time worked will not be long enough for the teacher to have created 27 worksheets. * Check All That Are True*
6 hours, 10 hours, 8 hours, 2 hours, 4 hours
Answers
Answer:
2 hours, 4 hours
Step-by-step explanation:
So lets go over what we know.
There are already 10 worksheets created.
Every 1 hour 3 more are made.
27 worksheets need to be made.
Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:
27-10
=
17
Now, lets divide the amount of worksheets we still need, by how many we make each hour:
17/3
=
Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.
Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.
Hope this helps! ;)

The equation of a line in slope intercept form that is perpendicular to y=-1/3 x +5 and goes through the point (-1,3)
Answers
Answer:
y = 3x + 6
Step-by-step explanation:
The general equation of a line is;
y = mx + b
where m is the slope and b is the y intercept
The slope of the first line is -1/3
when two lines are perpendicular, the product of their slopes is equal to -1
Thus;
-1/3 * m2 = -1
-m2 = -3
m2 = 3
So the equation of the second line is;
y = 3x + b
To get b, we substitute the coordinates of the point (-1,3)
We substitute -1 for x and 3 for y
so, we have;
3 = 3(-1) + b
3 = -3 + b
b = 3 + 3
b = 6
So we have the second equation as;
y = 3x + 6

Answer:
1.32/100
Step-by-step explanation:
Address input parameters and values. Input parameters and values: The decimal number = 1.32Write it as a fraction ; 1.32/1Multiply 100 to both numerator and denominator(1.32×100)/(1×100) = 132/100
It can be written as 132%= 132/100 or 132/100
4. To simplify 132/100 to its lowest terms, find LCM for the 132 and 100
4 is LCM for 132 and 100.
5. Divide numerator and denominator by 4
132/100=(132/4)/(100/4)=33/25.
33/25 is a simplest fraction for the decimal point number 1.32.
Answer:
132/100
Step-by-step explanation:
When you multiply by 10,100,1000.... you add zero. For example:132×10=1320 132×100=13200When you devide by 10,100,1000 you decrease the number starting from the right to left. For example: 132/10=13,2 132/100=1,32. NOTE it depends on the number of zeros.
