Jeans cost $12 and shirts cost $8 If you buy 2 pairs of jeans and 3 shirts, will they have any money left over? if so how much? Their answer: No they will not have any money left because 2 pairs of jeans would cost $26 and 3 shirts would cost $24 and 26+24=50 so they would spend exactly the right amount. EXPLAIN their mistake! What did they do wrong? What should their answer have been?
Answer:
$48
Step-by-step explanation:
A pair of jeans= $12
Two pair of jeans= $12*2= $24
A shirt= $8
3 shirts= $8*3= $24
So it would be $24+$24= $48.
They made their mistake when calculating the cost of the jeans by getting $26 instead of $24.
2. Compare CH3Cl and CCl4. Explain why one is polar and one is nonpolar. Be sure to use
the term symmetry in your explanation.
Answer:
Step-by-step explanation:
CH3Cl is polar while CCl4 is non polar.
When we consider whether something is polar or not we have to consider the following:
-Molecular symmetry
-Polar bonds (based on Electronegativity)
-Whether or not all the bonds are equal in magnitude
So for CCl4:
-All of the bonds are equal, in that all the electronegativity differences (delta EN) are the same.
-There are polar bonds as the delta EN between Cl (EN = 3.0) and C (EN=2.5) is 0.5 which means the bond is polar covalent
But when we look at the symmetry of the molecule (by drawing the lewis structure) there are no lone pairs, meaning that the molecule is symmetrical and therefore, it is non polar.
For CH3Cl:
-There are polar bonds here whether between C-H or C-Cl like above, both delta EN are greater than or equal to 0.5
-But, all of the bonds are not equal in strength. Cl (3.0) atoms have much higher electronegativity values than H (2.1) and there for they will "pull" the electrons closer and polarize the molecule. Therefore, the differences in bonds causes this molecule to be asymmetrical, and hence polar.
CH3Cl is polar due to an uneven electron distribution and net dipole moment, due to the different atoms attached. In contrast, CCl4 is nonpolar because it's symmetrical with the dipole moments cancelling out.
Explanation:The compounds CH3Cl and CCl4 vary in their polarities due to their molecular geometry, leading to different symmetries. CH3Cl has a tetrahedral shape but is polar because of the presence of the electronegative Chlorine atom and three Hydrogen atoms, creating an uneven distribution of electrons and thereby, a net dipole moment. On the other hand, CCl4 is also tetrahedral, but it's nonpolar due to its symmetry. As it has four Chlorine atoms evenly distributed around the Carbon atom, the dipole moments cancel out each other leading to no net dipole moment.

The percent of increase in airplane passengers from 600 to 1400 is 133%, calculated using the formula for percentage increase.
To calculate the percent of increase of airplane passengers from 600 to 1400, we need to use the formula for percentage increase, which is: Percentage Increase = ((New Number - Original Number) / Original Number) imes 100%.
Following the formula:
Subtract the original number of passengers (600) from the new number (1400) to get the increase in passengers: 1400 - 600 = 800.Divide the increase (800) by the original number (600): 800 / 600 = 1.33 (or 133%).Multiply by 100 to get the percent in percentage form, which gives us the percent of increase: 133 imes 100% = 133%.Therefore, the percent of increase in airplane passengers from 600 to 1400 is 133%.
14+14p=21 solve for p
Answer: 0.5
Step-by-step explanation: In this problem, we're asked to solve the following equation for p. Let's first switch 14 and 14p around so we have 14p + 14 = 21.
To solve this equation for p, we must first isolate the term containing p which in this case is 14p.
Since 14 is being added to 14p, we need to subtract 14 from both sides of the equation.
14p + 14 = 21
-14 -14
On the left side of the equation, the positive 14 and negative 14 cancel each other out and we have 14p. On the right side of the equation, we hav 21 - 14 which gives us 7.
Now we have the equation 14p = 7.
Since p is being multiplied by 14, to get p by itself, we divide both sides of the equation by 14.
On the left side of the equation the 14's cancel and we are left with p. On the right side of the equation, 7 divided by 14 is 0.5 which is our answer.
Therefore, p = 0.5 which is the solution for our equation.
Remember, you can always check your solution by substituting a number in for a variable to make sure the equation is true.

12k + 5k − 11m + 13m
To simplify the expression 12k + 5k - 11m + 13m, we can combine like terms by adding the coefficients of the like terms. The simplified expression is 17k + 2m.
Explanation:The expression 12k + 5k - 11m + 13m can be simplified by combining like terms. Like terms have the same variables raised to the same powers. In this expression, the terms 12k and 5k are like terms because they both have the variable k. Similarly, the terms -11m and 13m are like terms because they both have the variable m.
To simplify, we can add the coefficients of the like terms:
12k + 5k - 11m + 13m = (12 + 5)k + (-11 + 13)m
Therefore, the simplified expression is 17k + 2m.

Final answer:
The total area of the field being harvested by four workers, each with a plot of 5 by 8 feet, is 160 square feet.
Explanation:
The subject of this question is Mathematics, specifically, it involves calculating the total area of land worked by four workers. Each worker is given a plot that is 5 feet by 8 feet. To find the total area of the field that the four workers are harvesting, you multiply the area of one plot by the number of workers.
To calculate the area of one plot: Area = length * width = 5 feet * 8 feet = 40 square feet.
Now, since there are four workers each with a plot of this size, you multiply the area of one plot by the number of plots/workers:
Total area = 40 square feet/plot imes 4 plots = 160 square feet.
Therefore, the total area of the field being harvested by the four workers is 160 square feet.

A park designer wanted to place a fountain so that it was close to both the slide and the swings. Refer to the coordinate grid shown. Each unit on the grid represents 100 ft.
(A) find the distance from the slide to the foundation show your work.
(B) if each jump = 100ft, how far is it from the slide to the fountain?
Please show your work :)
Answer:
200 ft.
2 jumps
Step-by-step explanation:
The slide is placed at coordinates (-2,0) and the fountain is placed at coordinates (-2,-2).
(A) Therefore, using the distance between two known points formula, the distance from the slide to the fountain is given by
[tex]\sqrt{(-2 - ( -2))^{2} + (-2 - 0)^{2}} = \sqrt{(0 + 4)} = 2[/tex] units.
Now, given that each unit on the grid represents 100 ft.
So, the distance from slide to the fountain is (100 × 2) = 200 ft. (Answer)
(B) Now, if each jump = 100 ft, then the slide is 2 jumps apart from the fountain. (Answer)
We know the distance between two known points on the coordinate plane ([tex]x_{1},y_{1}[/tex]) and ([tex]x_{2},y_{2}[/tex]) is given by the following formula
Distance = [tex]\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2} )^{2}}[/tex]
The distance from the slide to the fountain is sqrt(29) units on the grid or 100*sqrt(29) feet. If each unit represents 100 ft, the distance is 100*sqrt(29) feet.
Explanation:To find the distance from the slide to the fountain, we need to determine the coordinates of both points on the grid. Let's assume the slide is located at point A (2,4) and the fountain is located at point B (7,6).
Using the distance formula, d = sqrt(([tex]x2 - x1)^2 + (y2 - y1)^2)[/tex], we can plug in the coordinates:
d = [tex]sqrt((7 - 2)^2 + (6 - 4)^2)[/tex] = sqrt(25 + 4) = sqrt(29).
So, the distance from the slide to the fountain is approximately sqrt(29) units on the grid or 100*sqrt(29) feet.
To determine the distance in feet if each unit on the grid represents 100 ft, we can simply multiply the distance by 100:
Distance = sqrt(29) * 100 = 100*sqrt(29) feet.

Answer:
1. The required slope m, for the context is[tex]m = 1.08[/tex]
2. The y-intercept in the context is [tex]a = y = 1052[/tex]
3. The graph is on Desmos.
Step-by-step explanation:
Given:
[tex]a = 1.08\times t + 1052[/tex]
Where,
a is the speed of sound wave.
t is the air temperature.
This is a linear model type equation.
Can be represented in the slope intercept form which is equal to
[tex]y = mx + c[/tex]
Where,
m = Slope of the line.
c = y-intercept.
Now if we compare the given model by slope intercept formula we get
[tex]m = 1.08\\\\c = 1052[/tex]
So ,the slope in the context of the problem is [tex]m = 1.08[/tex].
and the y intercept in the context of the problem [tex]a = c = y = 1052[/tex]
For Sketching the graph we require two point
put t = 0
∴ a = 1052
Let A (1052, 0) be one point.
put a = 0
∴ t = -974.07
Let B (0, -974.07) another point.
So, the x intercept of the linear model is [tex]t = x = -974.07[/tex]
Here in the graph
X axis represent temperature in degree, Fahrenheit.(t)
Y axis represent Speed of sound wave in feet per second.(a)
Scale on both axes:
1 cm = 100 feet per second on y-axis
1 cm = 100 degree Fahrenheit on x-axis
