300km because if 1cm=50km And it’s 6cm you have to do 50*6 to get C. 300km
The answer should be 6 pillows , hope this helped you
Answer:
y ≤0
Step-by-step explanation:
The range is the values that y can take
We see that y can be less than or equal to 0
y ≤0
Answer:
If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²
Then you do r * π *r which would be 78.5. so C is your answer.
Step-by-step explanation:
Answer: It will land on the bush after 1.25 seconds.
First, we will start with what we are given the equation: h(t) = -16t^2 + 30
Now, we should input a 5 for the h(t) because we want the seconds that will give us a height of 5 seconds.
5 = -16t^2 + 30
Solve the equation:
0 = -16t^2 + 25
To solve this, you could use the quadratic formula or factor out a -1 and you will have the difference of two squares.
Either way the answer is 1.25 seconds.
