The New York museum attracted 6,274,289, while the Chicago museum attracted 5,772,857.

Round to the nearest million. Note that if the number in the hundred-thousands place value is 5 or greater, round up. If it is 4 or less, round down.

6,274,289 => 6,000,000

5,772,857 => 6,000,000

Combine the two terms

6,000,000 + 6,000,000 = 12,000,000

a) 12,000,000 is your answer

hope this helps

The area of a square ice rink is 400 yd.². What is the perimeter of the rink in yards

MakcuM [25]

Answer:

80 yd^2

Step-by-step explanation:

Since the formula for squares is s^2, we can use this to set up an equation, which is

s^2=400

If we square root this, we get

s=20

The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

Jim was thinking of a number. Jim adds 20 to it, then doubles it and gets an answer of 99.2. What was the original number?

azamat

Alright, lets get started.

Jim was thinking of a number.

Suppose the number Jim was thinking, is x.

Jim adds 20 to it means number will be = $x+20$

And Jim doubles it, means $2*(x+20)$

Jim gets 99.2 and as per us, he gets $2*(x+20)$

So, making them equal

$2(x+20)=99.2$

$2x+40=99.2$

Subtracting 40 in both sides

$2x+40-40=99.2-40$

$2x=59.2$

$x=29.6$

It means the original number is 29.6. : Answer

Hope it will help :)

Anita sees in her nutrition book that a 7.5-ounce piece of cake has 900 calories. how many calories will she save if she takes o

Marianna [84]

$\bf \begin{array}{ccll}
\stackrel{cake}{oz}&calories\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
7.5&900\\
2.5&x
\end{array}\implies \cfrac{7.5}{2.5}=\cfrac{900}{x}\implies x=\cfrac{2.5\cdot 900}{7.5}$

so, the 2.5oz cake will be "x" calories, pheeew, she'll be taking in 900 - x less calories.
