Phil uses the model below to help him with multiple decimals. write a multiplication equation to represent the decimal model.
Multiplication equations can be modeled using decimal models.
The multiplication equation is: [tex]\mathbf{0.50 \times 0.90 = 0.45}[/tex]
From Phil model, we have the following highlights
50 boxes are shaded vertically90 boxes are shaded horizontallySo, the multiplication expression is:
[tex]\mathbf{\frac{50}{100} \times \frac{90}{100}}[/tex]
Express as decimals
[tex]\mathbf{0.50 \times 0.90}[/tex]
Multiply
[tex]\mathbf{0.50 \times 0.90 = 0.45}[/tex]
Hence, the multiplication equation is: [tex]\mathbf{0.50 \times 0.90 = 0.45}[/tex]

A table is on sale for 32% off. The sale price is $459.
What is the regular price?
the regular price is "x", which of course is the 100%, but we also know that $459 is 32% off that, hmmmmm well 100% - 32% = 68%, so $459 is really 68% of "x", because $459 is whatever "x" is minus 32%.
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 459&68 \end{array}\implies \cfrac{x}{459}=\cfrac{100}{68}\implies \cfrac{x}{459}=\cfrac{25}{17} \\\\\\ 17x = 11475\implies x = \cfrac{11475}{17}\implies x = 675[/tex]

(Giving brainliest, 5 stars and a thanks)
Answer:
3/7
Step-by-step explanation:
Judy is looking to buy a textbook. The book normally costs $75.82, but it is on sale for 35% below
the regular cost. How much will the book cost before taxes if Judy is to buy it while it is on sale?
Round to the nearest cent.
Answer:
$49.28 is the sale cost.
Step-by-step explanation:
0.35 x 75.82 = 26.537
75.82 - 26.537
= 49.283 and round
The selling cost of the book will be equal to $49.28.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Judy is looking to buy a textbook. The book normally costs $75.82, but it is on sale for 35% below the regular cost.
The selling cost of the book will be calculated as,
Selling Cost = 0.35 x 75.82 = 26.537
Selling Cost = 75.82 - 26.537
Selling Cost = 49.283

Proxima Centauri, our nearest star except for the sun, is about 4·1013 km from Earth. Find to one decimal place its distance in parsecs.
Step-by-step explanation:
The conversion for parsecs into meters is
1 parsec (pc) = [tex]3.09×10^{16}\:\text {m}[/tex]
So if Proxima Centauri is [tex]4×10^{13}\:\text{m}[/tex] away, then in terms of parsecs, this distance is

What is the Scale factor of 35 to 42
QUESTION. What is the Scale factor of 35 to 42
--------------------------------------
[tex]\boxed {\tt 25/35}[/tex]
---------------------------------------
The Scale Factor of 35/42 is the relative difference of one fraction or number (a) to another fraction or number prime (a′). In other words, 35/42 is what you multiply (number a) by to get (number a prime).
In a multiplication problem, we have a multiplier, multiplicand, and a product. You could say that (a) is the multiplier, the Scale Factor of 35/42 is the multiplicand, and (a′) is the product:
multiplier × multiplicand = product
multiplier × scale factor = product
a × 35/42 = a′
In the calculator below, you can enter the multiplier (a) as a fraction. We will then multiply it by the Scale Factor of 35/42 and give you the product (a′) in its simplest form possible.
