Pythagorean theorem in 3D
kiruha [24]

Answer:

d = 6.997 or 7

Step-by-step explanation:

Use Pythagorean Theorem to find the diagonal of the end of the prism

2^2 + 3^2 = C^2     Simplify

4 + 9 = C^2             Add

13 = C^2                  Take the square root of both sides

3.6 = C

Now plug this into the Pythagorean Theorem equation for the diagonal of the whole prism.

3.6^2 + 6^2 = d^2     Simplify

12.96 + 36 = d^2       Add

48.96 = d^2               Take the square root of both sides

6.997 = d                   This can be rounded up to 7, if needed

The equation sin(25") = 9/c
Marizza181 [45]

Option B: 21.3 in is the length of AB

Explanation:

The equation is \sin 25^{\circ}=\frac{9}{c}

To find the length of AB, let us equate,

c=\frac{9}{\sin 25^{\circ}}

Substituting the value for sin 25°, we get,

c=\frac{9}{0.4226}}

Dividing the values, we have

c=21.3

Thus, the length of AB is 21.3 in.

The correct answer is Option B.

A fair coin is tossed and a die is rolled. what is the probblloy of the coin being tails and the die landing on a 2
ZanzabumX [31]
The probility of getting a tail is 1 (tail) to 2 total possibilities which will be 1/2. The probility for rolling a "2" is 1 to a total possibility of 6 so the probability of 1/6. Since these are independent events and you want both to happen, you need to multiply the two results which will be 1/2 * 1/6 which equals 1/12.
