If there are 42 dogs in the neighborhood shelter and the shelter is now 60% full, 25 dogs can be accommodated.
What is proportion?A part, share, or quantity is a proportion when it is compared to the total. It can be any number between 0 and 1, 0, or 1. A number or percentage can be used to represent it. The proportion of Canadians who reside in a certain province is one illustration from official statistics. A unique kind of ratio called a proportion has the numerator and denominator combined. An illustration is the ratio of deaths to men, which is calculated by dividing deaths to men by deaths to men and women (i.e. the total population).
Here,
For every 100 dogs, there are 60 shelters.
For 42 dogs, there will be x shelters
100/60=42/x
60*42=100x
=60*42/100
=25.2 dogs that is approximately 25 dogs
25 dogs can the shelter provide for if it is currently at 60% capacity if there are 42 dogs at the local shelter.

Luke is driving from his house to the store. After driving 16 miles at a constant speed of 0.8 mile/minute, he realizes that he forgot his wallet. So,
he turns around and drives all the way back to his house at the same speed. The equation below models Luke's distance, in miles, from home as
he drives for t minutes.
d = -0.8t - 20 + 16
Using the given equation, match the number of minutes since Luke started driving from his house to his distance from the house.
12 minutes
27 minutes
31 minutes
7 minutes
10.4 miles on his return trip
5.6 miles on his trip to the restaurant
9.6 miles his trip to the restaurant
7.2 miles on his return trip
Answer:
10.4 miles on his return trip → 27 minutes
5.6 miles on his trip to the restaurant → 7 minutes
9.6 miles on his trip to the restaurant → 12 minutes
7.2 miles on his return trip → 31 minutes
Step-by-step explanation:
When solving, we note that on his trip to the restaurant, \(\left |t - 20 \right |\) is a negative number, while it is a positive number on his return trip
1) At 10.4 miles on his return trip, we have;
\(d = 10.4 = -0.8 \cdot \left |t - 20 \right |+ 16\)
Therefore;
(10.4 - 16)/(-0.8) = 7 = \(\left |t - 20 \right |\)
t = 20 + 7 = 27
The number of minutes since Luke started driving from his house, t = 27 minutes
2) At 5.6 miles on his trip to the restaurant, we have;
\(d = 5.6 = -0.8 \cdot \left |t - 20 \right |+ 16\)
Therefore;
(5.6 - 16)/(-0.8) = 13 = \(\left |t - 20 \right |\)
Here, t is less than 20 (minutes), therefore, t - 20 is negative, we get
t - 20 = -13
∴ t = 20+ (-13) = 7
The number of minutes since Luke started driving from his house when he is 5.6 miles on his trip to the restaurant, t = 7 minutes
3) At 9.6 miles on his trip to the restaurant, we have;
\(d = 9.6 = -0.8 \cdot \left |t - 20 \right |+ 16\)
Therefore;
(9.6 - 16)/(-0.8) = 8 = \(\left |t - 20 \right |\)
\(\left |t - 20 \right |\) is negative on his trip to the restaurant, therefore;
- \(\left |t - 20 \right |\) = 8
t - 20 = -8
t = 20 - 8 = 12
The number of minutes since he started driving from his house to when he is 9.6 miles on the his trip to the restaurant, t = 12 minutes
4) At 7.2 miles on his return trip, we have;
\(d = 7.2 = -0.8 \cdot \left |t - 20 \right |+ 16\)
Therefore;
(7.2 - 16)/(-0.8) = 11 = \(\left |t - 20 \right |\)
t = 20 + 11 = 31
At 7.2 miles from his house on the return trip, t = 31 minutes

The purpose of a(n) is to create an accurate drawing of either a very large or very small object
The purpose of a scale factor is to create an accurate drawing of either a very large or very small object.
What is scale factor?A scale factor can be defined as the ratio of two (2) corresponding length of sides or diameter in two similar geometric objects (shapes) such as equilateral triangles, quadrilaterals, polygons, river, planets in our solar system, etc.
Mathematically, the scale factor of a geometric object (shape) such as a map can be calculated by using this formula:
Scale factor = Dimension of image/Dimension of original figure
Generally speaking, a scale factor is typically used in conjunction with dilation, which is a type of transformation that changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased (enlarged) or decreased (reduced) based on the scale factor that is chosen and used.
In this context, we can reasonably infer and logically deduce that the purpose of a scale factor is simply for the creation of an accurate drawing of both very small geometric object and very large geometric object.

c) For every natural number k, if P(i) holds for every natural number i < k, then P(k) holds.
d) For every natural number k, if P(k) does not hold, then there is a smaller natural number i < k such that P(i) does not hold.
Answer:
A
Step-by-step explanation:
a) ✔️
This is the principle of mathematical induction. If P holds for the base case k=1 and we can show that if it holds for any arbitrary k (e.g. k=n) then it must also hold for the next value (e.g. k=n+1), then we have shown it holds for all natural numbers.
b) ❌
There is no guarantee that P holds for all natural numbers from the statement alone. It only guarantees that for any k where P does not hold, there exists a smaller number i where P does not hold.
c) ❌
This is the principle of weak mathematical induction. It only shows that if P holds for a given k and for all smaller values i then it must hold for k+1. It does not guarantee that P holds for all natural numbers.
d) ❌
This statement is the negation of the principle of mathematical induction. It is known as the "strong induction" principle, which assumes that if P does not hold for k, then there exists a smaller i where P does not hold. However, this principle is not sufficient to prove that P holds for all natural numbers k.

What is P(greater than 1 or divisor of 2)?
The probability of picking a number greater than 1 or a divisor of 2 is 3/4.
Calculating the probability P(greater than 1 or divisor of 2)?The numbers greater than 1 or divisor of 2 in the set {1, 2, 3, 4} are {2, 3, 4}.
Therefore, the probability of picking a number greater than 1 or a divisor of 2 is:
P(greater than 1 or divisor of 2) = P(2 or 3 or 4) = P(2) + P(3) + P(4)
Since there are four equally likely outcomes, the probability of each individual outcome is 1/4. Thus, we have:
P(greater than 1 or divisor of 2) = 1/4 + 1/4 + 1/4 = 3/4

\(y=-\frac{1}{2}x\)Find the value that makes the ratios equal. 63, 8 to 7
The value that makes the ratios equal is \(\frac{8}{9}\) .
Step 1: Set up the proportion.
The given ratio is 63:8, and we want to find the value that makes it equal to the ratio 7:x (where x is the unknown value). So, the proportion can be written as:
\(\frac{63}{8}\)= \(\frac{7}{x}\)
Step 2: Solve for x.
To solve for x, cross-multiply:
63 × x = 8 × 7
Step 3: Simplify the equation.
63x = 56
Step 4: Isolate x.
Divide both sides of the equation by 63:
x = \(\frac{56}{63}\)
Step 5: Simplify the fraction.
Both 56 and 63 are divisible by 7, so simplify the fraction:
