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.

Answer:

80 ounces

Step-by-step explanation:

In one pint, there is 16 ounces. Thus, if she picked five pints, 16 × 5 = 80 ounces.

Another way to solve this problem is by setting a proportion.

  • \frac{2cups}{1pint} = \frac{10cups}{5pints}
  • \frac{8ounces}{1cup} \frac{80ounces}{10cups}

Therefore, the answer is 80 ounces.

Calculate the principal amount which earns $500 simple interest over 3 Years at a rate of 8% p.a round to the nearest cent
timama [110]
$500 was earned over 3 years
so, to find one year
500 ÷ 3 = $166.67

Interest for one year is $166.67
Interest rate for one year is 8%

8% = 166.67
1% = $20.83
100% = $2083.33

Principal amount is $2083.33

Find the greatest common factor: 4ab^2 c^4-2a^2 b^3 c^2+6a^3 b^4 c
Tatiana [17]
Well the GCF is the number that can be used to simplify, or that fits in all of your numbers for example this are all small numbers so 2 should fit in all of them 2 fits in 4 two times 2 fits in 2 one time and 2 fits in 6 three times now lets check our variable, to find the GCF of the variable first chekc if they all have the same if they don't u can't get none of taht variebles out, but if they repeat in all like the a u will take out the smallest amount out, for example the a as one in the degree of 1 the other in to the 2 degree and the last one to teh 3 degree well the smallest degree will be 1 so u will only take 1 a out so now ur GCF looks like 2a... Lets check the other variables, b is used in all of them and the smallest degree is b2 so we will take out 2 b's out so now my GCF looks like 2ab2 now lets check our last variable the, the c has the smallest degree of 1 so we will only take 1 c out
this means our final GCF is "2ab2c"
