Answer:
The required list is: 0 car and 37 truck; 8 car and 30 truck; 16 car and 23 truck; 24 car and 16 truck; 32 car and 9 truck;
Step-by-step explanation:
Consider the provided information.
A toll collector on a highway receives $8 for trucks and $7 for cars, at the end she collected $296.
Let t represents the number of trucks and c represents the number of cars pass through highway.
The number of trucks should be natural number.
Substitute c=0 in
Substitute c=8 in
Substitute c=16 in
Substitute c=24 in
Substitute c=32 in
Hence, the required list is: 0 car and 37 truck; 8 car and 30 truck; 16 car and 23 truck; 24 car and 16 truck; 32 car and 9 truck;
B=1.25 so i think im not so good with this but i try if its wrong nvr listen to me
Answer:
What is 9+10? It's 19
Step-by-step explanation:
Omg, thank you so much again!!!
You're da best!!!
<h3>Given</h3>
- Set A: A = {-26, -25, -24, -23, - 22, - 21}
- Set B: B ∈ {x: x is even, x ≥ 6 and x ≤ 20}
<h3>(a) </h3>
<em />
<em>Cardinality means the number of elements in the set.</em>
Cardinality of the set A:
n(A) = 6, since we can count 6 elements.
Set B has even numbers between 6 and 20, both included:
- B = {6, 8, 10, 12, 14, 16, 18, 20}
Then its cardinality is:
<h3>(b) </h3>
To solve this we need to compare the elements of sets A or B with numbers given:
- -22 ∈ A, True ⇒ -22 is listed as element of A
- 6 ∈ B, True ⇒ 6 is listed as element of B
- - 21 ∉ A, False ⇒ - 21 is listed as element of A
- 2 ∈ B, False ⇒ 2 is not listed as element of B
