Answer:
80 cm^3 (cm cubed)
Step-by-step explanation:
5 x 2 x 8
Answer:
The nearest option is -3 (negative 3)
So, Option B is correct.
Step-by-step explanation:
We need to solve the inequality 
Solving:
Step 1: Switching sides of inequality and reversing the inequality

Step 2: Adding 4 on both sides

Step 3: Dividing both sides by -3 and reversing the inequality

The nearest option is -3 (negative 3)
So, Option B is correct.
Answer:
16 seconds (Approximately)
Step-by-step explanation:
Given:
The function that gives the distance of snowboarder from the bottom of hill with time 'x' is:

Final position of the snowboarder is 
Now, plugging in 100 for 'd' and solving for 'x', we get:

Adding -1100 both sides, we get:

Dividing both sides by -4, we get:

Taking square root and neglecting the negative root as time can't be negative. So,

Therefore, after 16 seconds, the snowboarder will be at a distance of 100 ft from bottom of hill.
2/7.
2/7 + 5/7 =1 Just add the numerator if the denominator is the same
