What is 16+(48/8)
and please do not give me a fraction i want a whole number for this answer, thank you

Answers

Answer: If the entry is a fraction only, leave the whole number field blank. This is the greater of the two entries. After determining which entry is greater, the compare fractions calculator will show its work and give a detailed explanation of each step it took to arrive at the answer.

Step-by-step explanation:

the answer 22
The answer is 22, because if you divide 48 by 8 you will get 6. ( You have to solve what’s in the brackets first!)
Then after you get 6, you will do 16+6 which equals to 22

The theme park company is building a scale model of the killer whale stadium main show tank for an investor's presentation. Each dimension will be made 6 times smaller to accommodate the mock-up in the presentation room. How many times smaller than the actual volume is the volume of the mock-up?

Answers

In step 1, you found the volume (in cubic feet) of the main tank. If the maximum density of killer whales per cubic foot is 0.000011142, what is the maximum number of killer whales allowed in the main show tank at any given time? You must explain your answer using words, and you must show all work and calculations to receive credit.
density of whale * volume of main show tank


0.000011142* 179503.33=2
If you were to take a cross section parallel to the base of one of the holding tanks, how would you describe the shape?
A sphere
The main tank has a radius of 70 feet. What is the volume of the quarter-sphered sized tank? Round your answer to the nearest whole number. You must explain your answer using words, and you must show all work and calculations to receive credit.

sphere sized tank:
4/3*3.14(70^3) = 1,436,026.67

Main tank:

1,436,026.67/4= 359,007 (rounded)

The holding tanks are congruent in size, and both are in the shape of a cylinder that has been cut in half vertically. The bottom of the tank is a curved surface. What is the volume of both tanks if the radius of tank #1 is 15 feet and the height of tank #2 is 120 feet? You must explain your answer using words, and you must show all work and calculations to receive credit.
The stadium is in need of a medical pool to attend to injured or sick whales. The pool will be located adjacent to the holding tanks. Your job is to design a medical pool using a 3-dimensional polyhedral shape you learned about in this module. For safety reasons, the tank can be no more than one-fourth the volume of a holding tank. You will need to submit a 2-dimensional drawing, the dimensions, the volume of your pool, and proof that the pool's volume is no more than one-fourth the volume of a holding tank to your instructor.

Using the same information from #5, what percent of change occurred from the actual tank to the mock-up of the tank?
21984.4% change
-When the salt decreased, so did the density of the water

-you need to add the amount of salt that the water needs in order to get the water back to normal, then observe the whale's behavior
V=3.14r^2h
3.14 *15^2* 120
706.5*120
=84780 for both tanks because the tanks are half of a cylinder. 

...one tank is 42,390

What's substitution for x=y-7;x+8y=2

Answers

X=2-8y
y=x+7
y=2-8y+7
9y=2+7
9y=9
y=1
x=y−7;x+8y=2
Step: Solve x=y−7 for x:Step: Substitute y−7 for x in x+8y=2:
x+8y
=2y−7+8y=2
9y−7=2(Simplify both sides of the equation)
9y−7+7=2+7(Add 7 to both sides)9y=9
9y/9=9/9(Divide both sides by 9)
y=1
Step: Substitute 1 for y in x=y−7:x=y−7
x=1−7
x=−6(Simplify both sides of the equation)
Answer:x=−6 and y=1
