find a proposition with three variable p, q and r that is true when at most one of the three variables is true, and false otherwise
Three variable p, q and r that is true when at most one of the three variables is true.
How do you identify a proposition?
Propositions are the name for certain types of phrases. A proposition is said to have a "true" truth value if it is true; a "false" truth value if it is untrue. Propositions include statements like "Grass is green" and "2 + 5 = 5". The first claim is true, whereas the second is wrong in terms of truth value.Atmost means maximum.
We have three variables: p,q and r. Maximum one of the three variable is true. However we dont know which variable is true.
Case 1: No variable is true : ¬p ∧¬q∧¬r
Case 2 : p variable is true: p ∧¬q∧¬r
Case 3: q variable is true : ¬p ∧q∧¬r
Case 4 : r variable is true : ¬p ∧¬q∧r
One of the 4 cases has to be true . Thus Case1 or Case 2 or Case3 or Case 4 is true. So we need to take comjuction of the propsitions in each case.
(¬p ∧¬q∧¬r) v (p ∧¬q∧¬r) v (¬p ∧q∧¬r) v (¬p ∧¬q∧r)

The diorama of a town uses the scale 5 inches : 10 miles. If the diorama measures approximately 60 inches across, what is the approximate measure of town?
Answer: 120 miles
Step-by-step explanation:
We will set up a proportion to solve.
Set up a proportion:
[tex]\displaystyle \frac{5\text{ inches}}{10\text{ miles}} =\frac{60\text{ inches}}{x\text{ miles}}[/tex]
Cross-multiply:
5 * x = 60 * 10
Multiply:
5x = 600
Divide both sides by 5:
x = 120 miles

Solve for the value of r.
52°
(4r-6)⁰
The value of r is 11°
How to determine the valueFrom the information given, we have that;
52°(4r-6)⁰Both angles are complementary angles.
It is important to note that complementary angles sum up to 90 degrees
Then, we have;
52 ° + 4r - 6° = 90°
collect like terms
4r + 46° = 90 °
4r = 90 - 46
4r = 44
Make 'r' the subject of formula
Divide both sides by 4
4r/4 = 44/4
r = 11°
Thus, the value of r is 11°

Answer:
no answer
Perhaps: E -45
Step-by-step explanation:
(2x + 4) = 14
2x + 4 = 14
2x = 10
x = 5
This equation has only 1 solution.
There cannot be the product of the "solutions" when there is only 1 solution.

300 teenagers went to the zoo.
How to find the how many teenagers went to the zoo?given that
Tickets to the zoo cost $4 for children.
Tickets to the zoo cost $5 for teenagers.
Tickets to the zoo cost $6 for adults.
1200 people come to the zoo every day.
on a certian day, the total revenue at the zoo was $5300.
Let the number of adults be x.
The number of teenagers be y.
and the number of children that went to the zoo 8y/3.
Consider the question
1200 people come to the zoo every day.
x + y + 8y/3 = 1200
now, take L.C.M between y and 8y/3
[tex]x + \frac{(3y + 8y)}{3} = 1200 \\ x + \frac{11y}{3} = 1200[/tex]
now multiply with 3 to this equation.
3x + 11y = 3600 .......................(1)
tickets to the zoo cost $4 for children, $5 for teenagers and $6 for adults.
according to the question
6x + 5y + 32y/3 = 5300
Now take the L.C.M between 5y and 32y/3
6x + 47y/3 = 5300
now multiply with 3 to this equation.
18x + 47y = 15900 ...................(2)
now, multiply equation (1) with 6
18x + 66y = 21600 .....................(3)
now, subtract equation (1) in equation (2)
(18x - 18x) + (66y - 47y) = (21600 - 15900)
19y = 5700
y = 5700/19
y = 300

Divide/scale down to solve for the missing percent.
The coins that represent the 20 5 of her coins that is 280 are 56 coins.
We know that:
Fatoumata has a collection of 280 coins.
Now, we need to tell how many coins will be its 20 %.
For this we will calculate 20 percent of 280
So, number of coins = N will be:
N = 20 % of 280
N = 20 % × 280
N = 20 / 100 × 280
N = 2 × 28
N = 56 coins
Therefore, we get that, the coins that represent the 20 5 of her coins that is 280 are 56 coins.

Let g(x)=-1/2x+ 6 and h (x) =g(x)-3 which statement descibes the graph of h(x)?
The statement describing the graph of h(x) is "The graph of h(x) is a vertical translation of the graph of g(x) down 3 units".
In the question, are given two graphs g(x) = - (1/2)x + 6, and h(x) = g(x) - 3.
We are asked for the statement that best describes h(x).
Now, h(x) = g(x) - 3, can be seen as the translation of g(x).
For any graph m(x), n(x) is its translation if n(x) = m(x + p) + q.
The translation is vertical is q ≠ 0, and horizontal when p ≠ 0. Also,
if p > 0, then the horizontal translation is p units right,if p < 0, then the horizonal translation is |p| units left,if q > 0, then the vertical translation is q units up, andif q < 0, then the vertical translation is |q| units down.For, h(x) = g(x) - 3, when we compare it with n(x) = m(x + p) + q, we have p = 0, and q = -3.
Since, q ≠ 0, we have vertical translation, and since q < 0, the translation is |q| units down.
Thus, The statement describing the graph of h(x) is "The graph of h(x) is a vertical translation of the graph of g(x) down 3 units".
