Given: $\textsf{45 + x = 75}$

Need: $\textsf{The value of the unknown x}$

Solution: In order to solve for the unknown we must subtract 45 from both sides which would isolate x and given us the value.

<u>Subtract 45 from both sides</u>

$\textsf{45 - 45 + x = 75 - 45}$

$\textsf{x = 75 - 45}$

$\textsf{x = 30}$

After simplifying the expression we were able to determine that x is equal to 30.

You roll a six-sided die. Find the probability of each of the following scenarios

romanna [79]

Answer:

a) $1/2$

b) $5/6$

c) $2/3$

Step-by-step explanation:

Rolling a number greater than 3 means you can roll a 4, 5, or 6, which contains rolling a 6. So, the probability is $(1+1+1)/6=3/6=\boxed{1/2}$

Rolling a number less than 5 means you can roll a 1, 2, 3, or 4, but because you could also roll an even number, so you could also roll a 6.

So, the probability is $(1+1+1+1+1)/6=\boxed{5/6}$

Rolling a 4 or an odd number means you can roll a 1, 3, 5, or 4. So, the probability is $(1+1+1+1)/6=4/6=\boxed{2/3}$

A video camera is being mounted on a bank wall so as to have a good view of the head teller. Find the angle of depression that t

Sever21 [200]

Answer:

The angle of depression of the lens must be 26.3°

Step-by-step explanation:

Here we have a right triangle with the opposite side to the angle equal to 5.93 feet and the adjacent side to the angle equal to 12.02 feet. Therefore we just need to use the tangent definition to find the angle.

$tan(\alpha)=\frac{5.93 ft}{12.02 ft}=0.49$

$\alpha=tan^{-1}(0.49)=26.3^{\circ}$

The angle of depression of the lens must be 26.3°

I hope it helps you!
