Beach Mark is a multiplication to remember
Answer:
0.5220
Step-by-step explanation:
Since the probability of contamination is 0.15, the probability of no contamination is 1 - 0.15 = 0.85
The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625
This is 0.5220 to four decimal
Answer:
Step-by-step explanation:
So, what is a quotient? Well, a quotient is like the sum, difference and product. When you add two numbers you get their sum, difference is for subtraction and product is for multiplication. So quotient is for division, or in other words the answer to a division problem.
Now, it's asking for the quotient of 91 and x, it isn't specifying which is being divided by which but it sound like it wants the first divided by the second. So that's 91 divided by x
Answer:
The time taken for the flare to hit the ground is approximately 10.7 seconds.
Step-by-step explanation:
Given : Suppose a flare is shot from the top of a 120 foot building at a speed of 160 feet per second. The equation 
models the h height at t seconds of the flare.
To find : How long will it take for the flare to hit the ground?
Solution :
The equation models the h height at t seconds of the flare.
The flare to hit the ground when h=0.
Substitute in the equation,
Applying quadratic formula, 
Where, a=-16, b=160 and c=120
Reject the negative value.
Therefore, the time taken for the flare to hit the ground is approximately 10.7 seconds.
