Answer:
h = √(44) ft
Step-by-step explanation:
Just looked back and A is actually the area because the unit was ft².
Area of a right isosceles triangle is half the area of a square.
A = ½S²
in this case your side is h.
A = ½h²
2A = h²
√(2A) = h
√(2(22)) = h
√(44) = h
plug that in your calculator for the answer.
Answer: 205 miles in 5 hours
Step-by-step explanation:
The way to find our answer is to first find how many miles the car can go in one hour. We would se the equation (123 divided by 3 to find our answer) which would give us 41 miles per hour. Then, we would proceed to multiply 41 by 5 which would give us our answer, 205 miles in 5 hours. Please correct me if I'm wrong!
1 root.
The reasoning is the same for your other question except x is positive this time round giving x=8 as your only root.
The result is <span>B. 1638.</span>
To calculate this, we will use both an addition and a multiplication rule. The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens, you will use the addition rule. <span>The multiplication rule calculates the probability that both of two events will occur.
First, there are two possibilities for winning exactly one match:
1. To win the first match and lose the second one.
2. To lose the first match and win the second one.
9% = 0.09 is the probability of winning. The probability of losing is 1-0.09 = 0.91. To calculate the probability of winning </span><span>the first match and losing the second one and vice versa, we will use the multiplication rule:
</span>1. 0.09 × 0.91 = 0.0819
2. 0.91 × 0.09 = 0.0819
We want to either one of these events to happen, so using the addition rule, we have:
0.0819 + 0.0819 = 0.1638
In 10,000 matches:
0.1638 × 10,000 = 1,638
Answer:
B
Step-by-step explanation:
y = (x + 1)/x
xy = x + 1
xy - x = 1
x(y - 1) = 1
x = 1/(y - 1)
Interswitch variables
f^-1(x) = 1/(x - 1)
