You and a friend go to Tacos Galore for lunch. You order three soft tacos and three burritos, and your total bill is $11.25. Your friend’s bill is $10.00 for four soft tacos and two burritos. How much do soft tacos cost? How much do burritos cost? Explain and show work
The cost of a soft taco is $1.25 and the cost of a burrito is $2.50.
Let the cost of a soft taco would be t and,
The cost of a burrito would be b
As per the given question, the equations would be as
3t+3b=11.25 ...(i)
4t+2b=10 ...(ii)
With the two equations in that form, an elimination solution is probably the simplest.
Multiply each equation by a constant so that the coefficients of b are opposite so that when the two equations are joined, b is eliminated.
-6t-6b = -22.50
12t+6b = 30.00
_____________
6t = 7.50
t = 7.50/6 = 1.25
Substitute the value of t = 1.25 in equation (ii), and solve for b
4(1.25)+2b=10
5+2b=10
2b=5
b=2.50
Thus, the cost of a soft taco is $1.25 and the cost of a burrito is $2.50.

What is discrete quantity?
A discrete quantity has a limited range of possible values. For instance, the number of students in a classroom is a discrete quantity because the range of possible values is not continuous and can only be a positive integer.
It can only have certain values, not just any value, according to the definition of discrete. One discrete quantity is the number of sheep in a field.
Consider, the first statement

What is the slope of the line that passes through the points (-5,2) and (-1,-6)
Answer:
Slope = -2
Step-by-step explanation:
Slope of Line passes through two Points [tex](x_{1},y_{1} )[/tex] and [tex](x_{2},y_{2} )[/tex]
is given by [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
So by Substitution
[tex]m=\frac{-6- 2 }{-1 - (-5)}=\frac{-8}{4} =-2[/tex]
Write the equation of the line in slope - intercept form
The equation of line in slope-intercept form is y = 2x + 1
Q. What is Equation of line ?
A straight line's general equation is y = mx + b, where m denotes the gradient or slope and y = b denotes the point at which the line crosses the y-axis. On the y-axis, this value b is referred to as the intercept.
We know the equation of line is
y = mx + b
where,
m = slope
b = y - intercept
To form an equation we need to find 'b' and 'm'.
so, first find 'b' i.e, y - intercept
For that, you just need to see the red line cuts the y-axis at its sharp grid means not in middle of the grid.
So, by observing the graph we see y = 1 where the red line cuts the y-axis
so we get, b = 1 means y-intercept
Now, we need to find slope (m).
For that, we know slope = rise / run
So take any point on graph which is easily to recognize the (x,y) points on graph.
Here I take the point (2, 5).
Now mark that point and find rise and run values.
rise = 4 (count from y = 1 to y = 5 )
run = 2 (count from x = 0 to x = 2)
Now, put the values and get the slope.
slope (m) = 4 / 2
= 2
Now, put the y-intercept and slope values in equation of line .
y = mx + b
y = 2x + 1
Hence, the equation of line in slope-intercept form is y = 2x + 1

redo the probability calculation for pits in [1,3] and [2,2], assuming that each square contains a pit with probability 0.01, independent of the other squares. what can you say about the relative performance of a logical versus a probabilistic agent in this case?
The pit [2, 2]'s prior probability tends to be 0 and its posterior probability tends to be 1.
Compute the probabilities of Pits Each square in the Wumpus world do consist of a pit with the probability of 0.01 and consist of independent contents of the squares.
As suppose there are total of N/2 pits that are scattered randomly among the total of N squares. To compute the probabilities of the pits in [1, 3] and [2,2], consider that the probabilities of the assignments to complete where the other assignments doesn't gets off.
Thus, the total number of the 3-pit assignment rather remains consistent with the three assigned partial assignments here P 1,3 =true.Thus, in 21 assignment completes when the P 1,3 =true. Next the 55 assignment completes when the
P 1,3, = false.
Thus, it gives P(P 1.3 ) = a' (0.01(0.0001+0.0099+0.0099), 0.99(0.0001+ 0.0099)) = (0.1674, 0.8326)
While when the value of Pay = true, then there are basically four assignments that are partialenough with the total value of 0.0001, 0.0099, 0.0099, 0.9801, through the assignment gets completed.
Next when the value of Pa, = false, then there is only a single assignment that is partial with the value of 0.0001 that completes the assignments. Thus, then the final value of P (P2.2 ) is given asP(P2.2) = a' (0.01(0.0001+ 0.0099+0.0099+0.9801), 0.99x 0.0001) = (0.9902, 0.0098
Thus, the prior probability of the pit [2, 2] tends to be 0 and the posterior probability tends to be one (1).

a square has a side length that is increasing at a rate of 14 inches per hour. what is the rate of change of the area of the square when the side length is 8 inches
The rate of change of the area of the square when the side length is 8 inches is 224 inches per hour.
Let s be the side of the given square.
A = s²
dA/dt = d (s²)/dt
dA/dt = 2s × ds/dt
Given ds/dt= 14 inches per hour, s = 8 inches
dA/dt = 2×14×8
dA/dt = 224 inches per hour
The area of the square is s². Since we need to find the rate of change we need to differentiate the area with respect to time which will give us 2s × ds/dt. Once we replace the given values with their respective positions we will get the desired answer. Hence the rate of change in the area of the square is 224 inches per hour.

What is centroid?The centroid of a triangle is the place where the three medians of the triangle connect. It is sometimes defined as the point at where the three medians cross. A median line connects the middle of a side to the opposing vertex of a triangle. The centroid of a triangle is the point at where the triangle's three medians coincide (each median connecting a vertex with the midpoint of the opposite side).
Here,
IF If J is the centroid of CDE, this means that J divides CG, FE, DC, CE and DH into two equal parts.
The following expressions are therefore true
DG + GE = DE and DG = GE
Substituting
DG + DG = DE
2DG = DE
Given DE = 52
2DG = 52
DG = 52/2
DG = 26
Since DG = GE, hence GE = 26
Also DF + FC = DC and DF = FC
Since FC = 15, hence DF = 15
Also CH + HE = CE and CH = HE
Since HE = 14, hence CH = 14
CE = 14+14
CE = 28
