Henry and Holly Hitch are a couple, who like to eat out and go to the theater. In addition to the money it takes for these activities, they must get a babysitter for each evening out, which is done through their babysitting cooperative. During the coming year, they will have $12,000, and 300 hours of babysitting credits, to use for their dining out and theater visits. Each dinner evening takes 3 hours and costs $150, while each evening at the theater also takes 3 hours and costs $100. Use x to denote the number of dinners out and y to denote the number of theater visits. Write down Henry and Holly's time budget constraint and money budget constraint.
Answers
Answer:
See step-by-step explanation
Step-by-step explanation:
Table
To eat out ( x ) cost 150 $ and need 3 hours
To go to the theater ( y ) cost 100 $ and need 3 hours
Therefore Budget constraint:
150 * x + 100 * y ≤ 12000
And time constraint is:
3 * x + 3* y ≤ 300
General constraints x ≥ 0 y ≥ 0 and must be integer
Three vertices of parallelogram DEFG are D(-4, - 2), E(-3, 1) and F(3, 3). Find the coordinates of G.
Answers
Given:
The three vertices of parallelogram DEFG are D(-4, - 2), E(-3, 1) and F(3, 3).
To find:
The coordinates of vertex G.
Solution:
Let the coordinates of vertex G are (a,b).
We know that, diagonal of parallelogram bisect equal other. It means, the midpoints of both diagonals are same.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Two diagonals of the parallelogram DEFG are DF and EG.
[tex]\text{Midpoint of DF}=\text{Midpoint of EG}[/tex]
[tex]\left(\dfrac{-4+3}{2},\dfrac{-2+3}{2}\right)=\left(\dfrac{-3+a}{2},\dfrac{1+b}{2}\right)[/tex]
[tex]\left(\dfrac{-1}{2},\dfrac{1}{2}\right)=\left(\dfrac{-3+a}{2},\dfrac{1+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{-3+a}{2}=-\dfrac{1}{2}[/tex]
[tex]-3+a=-1[/tex]
[tex]a=-1+3[/tex]
[tex]a=2[/tex]
And,
[tex]\dfrac{1+b}{2}=\dfrac{1}{2}[/tex]
[tex]1+b=1[/tex]
[tex]b=1-1[/tex]
[tex]b=0[/tex]
Therefore, the coordinates of vertex G are (2,0).
The coordinates of vertex G of parallelogram DEFG is: (2, 0).
Recall:
Diagonals of a parallelogram bisects each other, meaning they divide each other into equal parts.Midpoint formula = [tex](\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})[/tex]The given vertices of parallelogram DEFG are:
D(-4, - 2), E(-3, 1) and F(3, 3)
Let (x, y) = coordinates of vertex G.
DF and EG are diagonals of parallelogram DEFG, therefore:
midpoint of DF = midpoint of EGFind midpoint of D(-4, - 2) and F(3, 3) using [tex](\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})[/tex]:
[tex](\frac{-4 + 3}{2}, \frac{-2 + 3}{2}) = (\frac{-1}{2}, \frac{1}{2})[/tex]
Find midpoint of E(-3, 1) and G(x, y) using [tex](\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})[/tex]:
[tex](\frac{-3 + x}{2}, \frac{1 + y}{2})[/tex]
Make the midpoint of DF equal to the midpoint of EG, then solve for x and y.
[tex]\frac{-1}{2}, \frac{1}{2} = \frac{-3 + x}{2}, \frac{1 + y}{2}[/tex]
Solve for x:[tex]\frac{-1}{2} = \frac{-3 + x}{2}[/tex]
Cross multiply[tex]2(-1) = 2(-3 + x)\\\\-2 = -6 + 2x\\\\-2 + 6 = 2x\\\\4 = 2x\\\\\mathbf{x = 2}[/tex]
Solve for y:[tex]\frac{1}{2} = \frac{1 + y}{2}[/tex]
Cross multiply[tex]2(1) = 2(1 + y)\\\\2 = 2 + 2y\\\\2 - 2 = 2y\\\\0 = 2y\\\\\mathbf{y = 0}[/tex]
Therefore, the coordinates of vertex G of parallelogram DEFG is: (2, 0).

John and Lucy take turns rolling two dice. If John rolls a pair larger than or equal to 10 he wins and the game stops. If Lucy rolls a pair strictly smaller than 10, she wins and the game stops. They keep rolling in turn until one of them wins. Suppose John rolls first. What is the probability that Lucy wins
Answers
Answer:
56.25%
Step-by-step explanation:
If John rolls first and Lucy rolls second, in order to find the probability that Lucy wins we need to multiply the probability that John's roll is less than 10 by the probability that Lucy's roll is less than 10. There are a total of 12 possible outcomes that can occur in a pair of dice, therefore John's probability of rolling less than a 10 would be [tex]\frac{9}{12}[/tex] which would also be the same probability of Lucy rolling smaller than a 10. Now we simply multiply this probability by itself...
[tex]\frac{9}{12} * \frac{9}{12} = \frac{81}{144}[/tex] or 0.5625
We can multiply this decimal by 100 to get the percentage probability
0.5625 * 100 = 56.25%
The probability of Lucy winning the game is 56.25%
Pietro is given a test question asking him to show that the sum of two odd integers is

Answers
Answer: second option Let (2a +1) be an odd number. Let (2b +1) be a different odd number. Because the sum of these two numbers, 2(a + b + 1), is a multiple of 2, it is an even number.
B. Let (2A + 1) and (2B + 1) are different odd numbers. sum of these odd number is 2(A+ B +1) is a multiple of 2.
What is even and odd number?Whole numbers in mathematics can also be divided into even and odd numbers. There isn't a single number that can be both even and odd, making odd and even numbers distinct sets of numbers. A number can be either even or odd. Odd numbers are ones that are not entirely divisible by two, whereas even numbers are entirely divisible by two.
Let (2A + 1) and (2B + 1) are different odd numbers. the sum of these odd numbers is 2(A+ B +1) is a multiple of 2. furthermore, let 2a and 2b be two even numbers so the sum of those two will also be an even number. Therefore the sum of two odd numbers is always even.

Which equation represents a line with a slope of -8 and
a y-intercept of 4?
y = -8x4
y = - 4x +8
y = -8x4
y = 8x+4
Answers
The equation y = -8x + 4 represents the given problem.
What is slope and y-intercept?'The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
An intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis.'
According to the given problem,
We know,
Equation of a line can be represented as,
y = mx + c, where, m = slope
c = y-intercept
Slope of the line = -8
Y-intercept of the line = 4
Therefore,
The equation of the line:
⇒ y = -8 + 4
Hence, we can conclude, the equation y = -8x + 4 represents the given line.

Study the pattern in the equations. Use your observations to solve the equation for a. Express your answer in terms of
log4x 2^a = 3
Answers
Answer:
(log64x³) / 2 log = a
Step-by-step explanation:
Given the equation :
log4x 2^a = 3
Recall: If :
loga b = c becomes ; a^c = b
log4x 2^a = 3 ; becomes ; (4x)^3 = 2^a
4^3 * x^3 = 2^a
64x^3 = 2a
log64x³ = log 2a
log64x³ = 2 log a
Divide both sides by 2 log
(log64x³) / 2 log = 2 log a / 2 log
(log64x³) / 2 log = a
