A 0.8-liter bottle of Mexican wine costs 90 pesos. At that price, how much would a half-gallon jug of the same wine cost in dollars?
A half-gallon jug of the same wine would cost $10.82
How much would a half-gallon jug of the same wine cost in dollars?The given parameter is:
0.8-liter bottle = 90 pesos
As a general rule of conversion
1 liter = 0.26 gallon
This means that:
0.8 liter = 0.8 * 0.26 gallon
Evaluate
0.8 liter = 0.208 gallon
Substitute 0.8 liter = 0.208 gallon in 0.8-liter bottle = 90 pesos
0.208 gallon = 90 pesos
Divide both sides by 0.208
1 gallon = 432.69 pesos
Divide both sides by 2
0.5 gallon = 216.35 pesos
1 peso = 0.050 United States Dollar
So, we have:
0.5 gallon = 216.35 * $0.05
Evaluate
0.5 gallon = $10.82
Hence, a half-gallon jug of the same wine would cost $10.82

Find all possible values of each expression. Suppose 3
The inequality that describes the possible values of the expression is:
[tex]0 < \frac{b}{3a} - \frac{a}{3b} < \frac{9}{60}[/tex]
What is the lower bound of values of the expression?The expression is given by:
[tex]\frac{b}{3a} - \frac{a}{3b}[/tex]
To find the lower bound, we try to see when the expression is negative, hence:
[tex]\frac{b}{3a} - \frac{a}{3b} < 0[/tex]
[tex]\frac{b}{3a} < \frac{a}{3b}[/tex]
Applying cross multiplication and simplifying the 3's, we have that:
[tex]b^2 < a^2[/tex]
From the bounds given, this expression will never be true, at most they can be equal, when:
a = b = 4.
Hence the lower bound of values of the expression is of 0.
What is the upper bound of values of the expression?The expression is a subtraction, hence we want to maximize the first term and minimize the second.
Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:
Maximize b, hence b = 5.Minimize a, hence a = 4.Then:
[tex]\frac{b}{3a} - \frac{a}{3b} = \frac{5}{12} - \frac{4}{15} = \frac{25 - 16}{60} = \frac{9}{60}[/tex]
Hence the bounds are:
[tex]0 < \frac{b}{3a} - \frac{a}{3b} < \frac{9}{60}[/tex]

The coefficient of determination of a set of data points is 0.93 and the slope of the regression line is -5.26. Determine the linear correlation coefficient of the data.
Answer:
- 0.964
Step-by-step explanation:
Given that Coefficient of determination (R^2) = 0.93
Slope of regression line = - 5.26
The linear correlation Coefficient =?
The Coefficient of determination (R^2) is used to obtain the proportion of explained variance of the regression line. It is the square of the linear correlation Coefficient (R).
Hence. To obtain the linear correlation Coefficient (R) from the Coefficient of determination (R^2); we take the square root of R^2
Therefore,
R = √R^2
R = √0.93
R = 0.9643650
R = 0.964
However, since the value of the slope is negative, this depicts a negative relationship between the variables, hence R will also be negative ;
Therefore, R = - 0.964
The linear correlation coefficient of the data is: -0.96
Recall:
Coefficient of determination = R²R represents the linear correlation coefficient.A negative slope of regression line suggests relationship between variables will be negative, hence linear correlation coefficient will be negative.Thus, given:
Coefficient of determination of a set of data points = 0.93
Slope of the regression line = -5.26
Therefore:
R² = 0.93
R = √0.93
R = 0.96
Since the slope the regression line is negative, R will be negative in this case.
Therefore, the linear correlation coefficient of the data is: -0.96Learn more about linear correlation coefficient on:

Mookie, Gandalf, and O’Malley are selling tickets to a play. Gandalf sold five less than three times the number of tickets Mookie sold. O’Malley sold one more than seven times the number of tickets Mookie sold. The number of tickets O’Malley sold is four more than twice the number of tickets that Mookie and Gandalf sold together. How many tickets did they sell in total?
9514 1404 393
Answer:
73
Step-by-step explanation:
Let m, g, o represent the numbers sold by Mookie, Gandalf, and O'Malley, respectively. Then the relations between these values are ...
g = 3m -5
o = 7m +1
o = 4 +2(m +g)
Equating expressions for o, we have ...
7m +1 = 4 +2(m +g)
Substituting for g, we have ...
7m +1 = 4 +2(m +(3m -5))
7m +1 = 8m -6
7 = m . . . . . . . . add 6-7m
g = 3·7 -5 = 16
o = 7·7 +1 = 50
The number sold in total is ...
m + g + o = 7 +16 +50 = 73
They sold 73 tickets in total.

Answer:

Step-by-step explanation:
Gonna solve it but you need to do the rest, the answers are all in the solution.
Expand the following:
(3 (x + 2) = 18, 3 x + 6 = 18)
3 (x + 2) = 3 x + 3 2:
((3 x + 3 2) = 18, 3 x + 6 = 18)
3×2 = 6:
(3 x + 6 = 18, 3 x + 6 = 18)
Subtract 6 from both sides:
(3 x + (6 - 6) = 18 - 6, 3 x + 6 = 18)
6 - 6 = 0:
(3 x = 18 - 6, 3 x + 6 = 18)
18 - 6 = 12:
(3 x = 12, 3 x + 6 = 18)
Divide both sides of 3 x = 12 by 3:
((3 x)/3 = 12/3, 3 x + 6 = 18)
3/3 = 1:
(x = 12/3, 3 x + 6 = 18)
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:
(x = 4, 3 x + 6 = 18)
Subtract 6 from both sides:
(x = 4, 3 x + (6 - 6) = 18 - 6)
6 - 6 = 0:
(x = 4, 3 x = 18 - 6)
18 - 6 = 12:
(x = 4, 3 x = 12)
Divide both sides of 3 x = 12 by 3:
(x = 4, (3 x)/3 = 12/3)
3/3 = 1:
(x = 4, x = 12/3)
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

Trout Street and Salmon Street are the same distance from the boardwalk to the intersection of 1st Street, Trout Street, and Salmon Street as shown in the diagram. Abby walks down 1st Street and stops when she reaches the boardwalk.
How far of a walk does she have to get to Trout Street?
Diagram shows triangle with base side labeled boardwalk and 2 legs labeled Trout Street and Salman Street. Segment labeled 1st street drawn from top vertex to base side is at right angle. Distance between segment and bottom right vertex is 800 yards.
Abby's walk to Trout Street is
yards.
When Abby's walk to Trout Street is 800 yards.
Distance is referred to as the length of a moving particle's real path. The shortest distance between a body's initial and final positions is referred to as displacement.
The distance between the segment and bottom right vertex is 800 yards.
The 1st street, Trout Street, and Salmon Street intersect at a point G.
Now, Trout street and Salmon street are at the same distance from the boardwalk.
From the figure, the distance between the boardwalk and salmon street is 800 yards.
Now the 1st street is perpendicular to line AE which is the distance between Trout street and Salmon street and hence AC = CE.
Therefore, When Abby's walk to Trout Street from the boardwalk is 800 yards.

For the triangles described, which of the following statements must be true? In triangle DEF, DE=8 in., DF=23 in., and ∡D=16°. In triangle PQR, PQ=23 in., PR=8 in., and ∡P=16°. (1 point) ∠Q≅∠F ∠R≅∠F DE¯¯¯¯¯¯¯¯≅PQ¯¯¯¯¯¯¯¯ ∠E≅∠Q
Answer:
∠Q≅∠F
Step-by-step explanation:
Two triangles are said to be congruent if all the three sides of the triangles are equal and all the three angles are equal.
Given that: In triangle DEF, DE=8 in., DF=23 in., and ∡D=16°. In triangle PQR, PQ=23 in., PR=8 in., and ∡P=16°.
Hence we can say that ΔDEF is congruent to ΔPQR. According to the side-angle-side (SAS) triangle congruence theorem: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
Therefore:
DF = PQ, DE = PR, EF = RQ, ∠D = ∠P, ∠E = ∠R and ∠F = ∠Q
