Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

$\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15$

Step 2: Divide the decrease by the original number

$1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2$

Step 3: Multiply the result by 100 to get a percent decrease

$0.2 \times 100\\\\= 20$

Therefore, the percent decrease of the price of paper per package is 20%

Note: If the percentage is negative, it means there was an increase and not a decrease.

How you know that the values of the digit in the numbers 1500,000 and 100,500 ate not the same

Sliva [168]

In this number 1500,000,

1 is at million place and 5 is at hundred thousand place

So, the value of 1 = 1 (1,000,000) = 1 million

And the value of 5 = 5 (100,000 ) = 500,000 = Five hundred thousand

In the second number 100,500

1 is at hundred thousand place and 5 is at hundred place

The value of 1 = 1 (100,000) = 100,000 = Hundred thousand

And the value of 5 = 5 (100 ) = 500 = Five hundred

Since the digits 1 and 5 both are at different places in both the numbers so 1,500,000 and 100,500 are not the same.

Find the length of the side marked x

ruslelena [56]

it's a right angled triangle so we will use hypotenuse formula to get the value of x

hypotenuse formula = a² + b² = c²

a = side of the triangle

b = base of traingle

c = hypotenuse ( can be written as h too)

and the formula can also be written as.

c² = a² + b²

therefore, x = 12.1

hope this answer helps you dear...take care!

Samantha read 22 books in 4 months. How many books would she read in 10 months?

kari74 [83]

Well first let's find out how many books she reads in 1 month.
1) 22 (books) ÷4 (months)=5.5 she reads 5.5 books in one month.
Now we multiply 5.5 by the amount of months she will be reading.
2) 5.5 (books) ×10 ( months)=55 books
SAMANTHA WILL READ 55 BOOKS IN 10 MONTHS
