1 answer:
Peterson will need 39 more tiles to completely cover the kitchen floor
Step-by-step explanation:
Given dimensions of kitchen are:
12 feet and 7 feet
In order to find the number of tiles for the kitchen, we have to first find the area of the kitchen
So,
Area of kitchen:
The area is 84 square feet which means 84 one square foot tiles are needed to completely cover the floor of kitchen.
As Peterson already has 45 tiles, so the more tiles she will need is:
Hence,
Peterson will need 39 more tiles to completely cover the kitchen floor

To find the equation we will put the values of x and y in the equations and then check if LHS=RHS.
- x=1
- y=9
Hence, Option B. y=5x+4 satisfies the system (1,9)
In a Chemical formula, Subscript figures tell us how numerous of the element to their upper-left there are in the patch.
What is a chemical formula?
- In chemistry, a chemical formula is a way of presenting information about the chemical proportions of titles that constitute a particular chemical emulsion or patch, using chemical element symbols, figures, and occasionally also other symbols, similar as hiatuses, dashes, classes, commas, and plus() and disadvantage( −) signs.
- These are limited to a single typographic line of symbols, which may include subscripts and subtitles.
- A chemical formula may indicate certain simple chemical structures, it isn't the same as a full chemical structural formula.
The subscript number indicates the total number of titles of an element present in a patch.
While witting a chemical formula, first we've to write the symbol of an element and also write the number at the bottom of the symbol.
For illustration,
is the chemical formula of the glucose patch. The glucose patch is made up of six carbon titles, twelve hydrogen titles, and 6 oxygen titles.
The number 6 of the carbon snippet is written after and at the bottom ( lower- right) of the symbol of carbon element (C). also, the number 12 is written lower-right of the symbol of hydrogen element (H), and the number 6 is written lower-right of the symbol of oxygen element( O).
thus, the subscript figures tell us how numerous of the element to their upper-left there are in the patch.
