Answer: 20 km
Step-by-step explanation: Let's assume a trajectory of Ships A (which is moving at 6 km/h) and B (which is moving at 4 km/h)
__________________
A 10 km B
And let's assume that who is going to the right is the positive.
Space (S) = S₀ + vt
For A, its space is SA = 0 + 6t
For B, its space is SB = 10 - 4t
They meet at SA = SB;
6t = 10 - 4t
6t + 4t = 10
10t = 10
t = 1h
If the bird is at 20 km/h and it will fly for 1h, it will travel 20 km
You need to be more specific, i can't answer the question without it
Answer:
The zeroes are and
On the graph, each of these zeroes represent the x-value where the equation will intersect with the x-axis.
Step-by-step explanation:
We have the quadratic equation
To factor this we need to find two numbers that fulfill the following:
They add up to 1
They multiply to give you -20
These two numbers are -4 and 5
This means that the quadratic equation in its factored form will be:
Now that we have the factored form, we need to set and solve for x
From this factored form, we can see that when and the result will be zero. Just to check we can plug in each of these x values
The result of this confirms that x=4 and x=-5 are indeed the zeroes of this equation.
Each of these zeroes represent the x-value where the equation will intersect with the x-axis.
Answer:
1. 3. 6.
Step-by-step explanation:
We are given that <span>Ellie had 44 books in her bookcase. She counted 32 fiction books, thus she has nonfiction book of about,
Nonfiction= 44-32= 12
Thus, Ellie has 32 fiction books and 12 nonfiction books. But we are tasked to find the ratio of the of fiction books to nonfictions books. This gives us,
32:12
Reducing 32:12 into simpler ratio by factoring 4 on both sides,
32:12=8*4:3*4=8:3
Therefore, Ellies Bookcase has a fiction to nonfiction ratio of 8:3 which is letter A.</span>
