Find the multiplicative inverse, or reciprocal, of . 5 over 9
Final answer:
The multiplicative inverse or reciprocal of the fraction 5/9 is 9/5, which is the result of flipping the numerator and denominator.
Explanation:
The multiplicative inverse, or reciprocal, of a fraction is another fraction in which the numerator and denominator are flipped. For the fraction 5 over 9, the multiplicative inverse is found simply by reversing the numerator and the denominator, turning it into 9 over 5.
To illustrate this with an example, let's consider the fraction ½. The reciprocal of ½ is 2, as their product equals 1 (1/2 x 2 = 1). Similarly, the reciprocal of 5/9 will be such that (5/9) x (9/5) = 1.
Hence, the reciprocal of 5/9 is 9/5.

The perimeter of a regular quadrilateral is 12 inches. What is its area?
plz help !!!
The required area of the regular quadrilateral is 9 square inches.
Given that,
The perimeter of a regular quadrilateral is 12 inches. What is its area is to be determined.
A quadrilateral is a four-sided shape, regular or nonregular.
Examples:- square, rectangle parallelogram etc.
Here,
A regular quadrilateral is a square.
the perimeter of the rectangle = 4 × side
12 = 4 × side
side = 12 / 4
Side = 3 inch
Area of the square = side²
Area of the square = 3²
Area of the square = 9 square inches
Thus, the required area of the regular quadrilateral is 9 square inches.

find least common denominator and rewrite the fractions
lets use 24: 24/3 = 8, 24/4 = 6, 24/8 = 3
so 2/3 = 16/24
1/4 = 6/24
4/8 = 12/24
now add them together:
16/24 + 6/24 + 12/24 = 34/24 which becomes 1 and 10/24 reducing to 1 and 5/12

How many items will Sandra and Teo have for sale in total? Write a mathematical question (order of operations), hen solve your expression to find the answer.
Plz help, u will be awarded 20 points if u help.
Sandra and Teo will have a total of 96 items for the bake sale. We find this by first multiplying the number of trays Sandra baked by the number of cookies per tray, then multiplying the number of Teo's brownie pans by the pieces per pan, and finally adding our two results together.
Explanation:The subject of the question is Mathematics, specifically it is an arithmetic problem involving multiplication and addition. It is a middle school grade level question.
To solve it, we need to multiply the number of trays Sandra baked by the number of cookies on each tray. So, 4 (trays) * 12 (cookies) = 48 cookies.
Next, multiply the number of brownie pans Teo baked by the number of pieces each pan was divided into. That is, 6 (pans) * 8 (pieces) = 48 brownies.
Finally, to find the total number of items for the bake sale, we simply add our two results: 48 (cookies) + 48 (brownies) = 96 items.
