That would be a 30% Decrease.

Here is how I found the answer:

Step 1: Find the difference between the two numbers by using this formula: Original Number - New number = Decrease.

Step 2: Divide the decrease by the original number and then multiply your answer by 100 by using this formula: Decrease / Original Number = % Decrease.

Now you can use these formulas to find any percentage decrease between two numbers.

Can anyone help me with this?
Vika [28.1K]

Answer:

x = 51

Step-by-step explanation:

The figure shown is a pentagon

The angles in a pentagon add up to equal 540

Which means that 77 + 107 + 156 + 149 + x = 540

                                    ^ ( note that we just created an equation that we can      

                                        use to solve for x )

We then solve for x using that equation

77 + 107 + 156 + 149 + x = 540  

step 1 combine like terms

77 + 107 + 156 + 149 = 489

we now have 489 + x = 540

step 2 subtract 489 from each side

489 - 489 cancels out

540 - 489 = 51

we're left with x = 51

If a cow has a mass of 9×1029×102 kilograms, and a blue whale has a mass of 1.8×1051.8×105 kilograms, which of these statements
STatiana [176]
Cow : 9 x 10^2 = 9 * 100 = 900
whale : 1.8 x 10^5 = 1.8 * 100,000 = 180,000

180,000/900 = 200

The blue whale has about 200 times more mass <==
