<h3>Answer: choice A) </h3><h3>tan(Y) = 6/7 and tan(Z) = 7/6</h3>

Recall that the tangent of an angle is equal to the ratio of the opposite over adjacent sides

tan(angle) = opposite/adjacent

For reference angle Y, the opposite side is XZ = 6 and the adjacent side is XY = 7, so,

tan(Y) = XZ/XY = 6/7

For tan(Z), things will swap. The opposite side is now XY = 7 and the adjacent side is now XZ = 6

tan(Z) = XY/XZ = 7/6

We do not use the hypotenuse sqrt(85) at all in this problem because the tangent ratio does not involve the hypotenuse.

Jonas needs to find the missing height of a box that has a length of 6 in, a width of 3 in, and a volume of 36 in3. Jonas needs
bearhunter [10]
So, the equation would be 6*3x=36
First, divide by 6 on both sides!
Then you get 3x=6
Divide by 3 to isolate x, and you get x=2
X represents the missing side, so the missing side equals two!

To check your answer, plug 2 back in for x! 6*3*2=36
6*6=36
36=36
So that means your answer is right!
I hope this helps!

I Need help fast I’d really appreciate it!
Charra [1.4K]

Step-by-step explanation:

a) The range at which the internal temperature can rise is from 2°F to 6°F, which means that in order fo the final temperature of the turkey to fall within the range of 165-170°F, we need to pull remove the turkey when the internal temperature is at a minimum of 164°F or a maximum of 168°F.

b) I'd rather err on the higher side of the internal temperature. After all, no one eats poultry cooked medium rare due to the high probability of salmonella poisoning and the 165-170°F is meant to destroy the microbes that causes food poisoning. Not only that, poultry meat gets sufficiently cooked at that range.

How much water should be added to 8 quarts of 90% antifreeze to get a 30% solution?
Serjik [45]

Answer:

16 quarts

Step-by-step explanation:

Let's say x is the volume of water.

Initially, the amount of antifreeze is the concentration times the volume: 0.90 (8).

After the water is added, the amount of antifreeze is the new concentration times the new volume: 0.30 (8 + x).

Since the amount of antifreeze doesn't change, we can set these equal and solve for x.

0.90 (8) = 0.30 (8 + x)

7.2 = 2.4 + 0.30 x

4.8 = 0.30 x

x = 16

16 quarts of water should be added.

What is the volume of a hemisphere with a diameter of 8.9 cm, rounded to the nearest tenth of a cubic centimeter?
Zarrin [17]

Answer:

The volume of the hemisphere is 1,475.73 cm³.

Step-by-step explanation:

Given that a hemisphere is half a sphere, to determine the volume of a hemisphere with a diameter of 8.9 cm, the following calculation must be performed, knowing that the volume of a sphere is equal to 4/3 πr³, and the radius is half the diameter:

8.9 x 2 = 17.8 / 2 = 8.9

(4/3 x 3.14 x 8.9³) / 2 = X

(1.333 x 3.14 x 704.969) / 2 = X

(4.18666 x 704.969) / 2 = X

2,951.47 / 2 = X

1,475.73 = X

Therefore, the volume of the hemisphere is 1,475.73 cm³.
