Answer:
c
Step-by-step explanation:associative: a+(b+c)=(a+b)+c
commutative: a+b=b+a
distributive: a(b+c)=ab+ac
inverse: I think it is a times 1/a=1, doesn't matter
help! Container ships sail all over the world to deliver cargo from port to port. Even though such ships can
weigh as much as 400,000 tons, they stay afloat because of the buoyant force exerted on them by the
water.
Below is a diagram of a container ship floating in the water. Its weight is represented by a downward
arrow and a negative number because the weight exerts a downward force on the boat. The buoyant
force of the water balances out the weight of the ship, so the ship can float. Describe an arrow that
would represent the buoyant force. What value should be associated with this arrow? Explain how this
situation relates to the concept of combining a number with its additive inverse.
Answer:
An object that weighs 100 tons and is floating is displacing exactly 100 tons of the fluid, and the buoyant force on it is 100 tons. The vertical forces on it are balanced (add up to zero), and that's why it isn't accelerating up or down.

Jerry has 7 3/4 dozen donuts. He purchased another 4.25 dozen donuts. How many dozens of donuts does he have now?
Answer:
12 dozen
Step-by-step explanation:
Relatively easy stuff, just recall fractionsA dozen means 12he has 7 dozen (7 x 12=84) and 3/4 dozen (3/4 x 12=9) so that's 84+9= 93 donutshe gets 4.25, which is the same as 4 1/4, so its 4 dozen (4 x 12=48) and 1/4 dozen (1/4 x 12=3) so that's 48+3= 51 donutsAdd what you got 93 + 51 = 144 donutsThen divide this by 12 to get the number of dozens144/12 = 12 dozenAnswer:
12 dozens of donuts
Step-by-step explanation:
First, you want to change the decimal into a fraction. The decimal, 4.25, is the same as 4 25/100. You can reduce 4 25/100 to 4 1/4 by diving both the numerator and denomiator by 25. Now that both of our numbers are fractins, we can just add the fractions up. 7 3/4 + 4 1/4 = 11 4/4 = 12\
Jerry got 12 dozens of donuts.

Michael is doing an underwater handstand. His feet are sticking up 0.5 meters above the surface of the water. Michael's hands are 1.8 meters directly below his feet.
What is the position of Michael's hands relative to the surface of the water?
Group of answer choices
A. 1.8 meters
B. 1.3 meters
C. 0.5 meters
D. -0.5 meters
E. -1.3 meters
F. -1.8 meters
Answer: 1.3 Meters or B
Step-by-step explanation:
To answer this question, it must be noted first that the reference points of the given distances in this item is (1) the surface of the water and (2) the feet. We are given with the distance from the hand to the feet, 1.8 m, and from the feet to the surface of the water, 0.5 m. To get the distance from the hands to the surface of the water, we just have to subtract the given distances giving us an answer of 1.3 m.
Answer:
e. -1.3 meters
Step-by-step explanation:
subtract 1.8 by 0.5 and you get 1.3 since youre below water level youd put - in front of 1.3 since its negative

2 times 4 which is eight, then subtract eight from 20. your answer is 12
X=12
So In your notes write
First you Mutiply the two factors 2 & 4, and then since eight is positive you will subtract it from the eight and the twenty. Youre left with X=12

Which sequence of transformations creates a similar, but not congruent, triangle?
A) Rotation and translation
B) Reflection and rotation
C) Dilation and rotation
D) Translation and reflection
Answer:
C) Dilation and rotation
Step-by-step explanation:
Dilation changes the size of the shape (how big or small the shape is), rather then changing the shape itself (into a completely different shape). The other options are transformations, but they only move the shape along the graph, nothing else. Hope this helps!
