A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?
bezimeni [28]

Answer:

A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.

Step-by-step explanation:

To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.

Find the quotient. x + 7 x ÷ 9 x
kicyunya [14]
The first step for solving this expression is to write the division as a fraction.
x + \frac{7x}{9} × x
Calculate the product.
\frac{7x X x}{9}
Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:
\frac{7 x^{1}X x^{1}  }{9}
Now multiply the terms with the same base by adding their exponents.
\frac{7 x^{1+1}}{9}
Finally,, add the numbers together to get your final answer.
x + \frac{7 x^{2}}{9}
Let me know if you have any further questions.

Mya wants to create a rectangular garden that will be 25 feet wide. She has 110 feet of
jok3333 [9.3K]

750 sq ft

Step-by-step explanation:

since the fencing is going around the perimeter, you have to have two sides with the width of 25 feet, you would use 50 feet of fencing for 2 of the sides. You will have 60 feet of fencing left, divided by 2 (length of the garden) = 30 feet long.

The area (length x width) or (25 x 30) = 750 sq ft of garden space. Draw a rectangle with 25 ft on two parallel sides and 30 ft on the other two sides and show these equation= 25 x 2= 50, 110 - 50 = 60

60 ÷ 2 = 30, 30 x 25 = 750
