A grocery store sells 2 boxes of cereal for $4.95. Which method can be used to
find the total cost c of purchasing n boxes of cereal?
O Multiply n by the cost of one box.
O Multiply n by c.
O Divide n by the cost of one box.
Divide n by c.
Answer:
Multiply n by the cost of the box.
Step-by-step explanation:
hey there,
< For these kinds of problems I always like making ratio tables.
2 boxes → $4.95
n boxes → $?
To find the thing we don't know in any ratio table (marked by "?"), you have to multiply the two opposites and then divide by the last one standing. I know that sounds confusing so let me explain...
"Two opposites" means the two values that are right across from each other, but do not include the unknown ("?"). In this example, the two diagonally across from each other are "n" amd "4.95". "2" and "?" can't be right across from each other because one of those is a "?".
Multiply the two opposites. n × 4.95. Let's not actually simplify since this isn't what we are doing here in this question and leave it like this:
n × 4.95 = (n × 4.95)
Now that we found that, we have to divide it by the last number available. The last number available that we haven't used yet is "2" (it obbviously can't be the unkown number "?").
(n × 4.95)/2
Whatever the result of the above equation is, is the answer.
(n × 4.95)/2 = ?
In our situation, "?" means "c". This is how you would solve any ratio table, it might seem tricky at first but it's actually super easy.
In this question, we are not asked to divide by two because they want to know a method of solving using the cost of one box.
[tex]\frac{(n*4.95)}{2} / 2[/tex]
n × (4.95/2)
4.95/2 is the cost of one box. Multiply that by "n" and there is your final answer. >

Pythagorean theorem
Answer:
a=3√77=26.3 ( rounded to the nearest tenth)
Step-by-step explanation:
hyp.=37
base=26
a²+b²=c²
a²=c²-b²
a²=37²-26²
a²= 693
a=√693
a=3√77=26.3 ( rounded to the nearest tenth)
Answer: [tex]\huge\boxed{26.3}[/tex]
Explanation...
Our hypotenuse =37
Our B = 26
___________________________________________________________
Rearrange Formula (A^2+B^2=C^2)...
A^2=C^2-B^2
A^2=37^2-26^2
37^2= 1396
26^2= 676
1396-676=√693
√693= 26.342
26.342=26.3

Noah wants to create a floor plan that is a scale drawing. The actual length of Wall C is 4 m. To represent Wall C, Noah draws a segment 16 cm long. What scale is he using?
Answer:
Scale using for plan ⇒ 1 m = 4 cm
Step-by-step explanation:
Given:
Actual length of wall = 4 m
Segment of wall = 16 cm long
Find:
Scale using for plan
Computation:
Actual length of wall = Segment of wall
4 m = 16 cm
1 m = 16 / 4 cm
1 m = 4 cm
Scale using for plan ⇒ 1 m = 4 cm
Answer:
Step-by-step explanation: it’s 1 m because it’s equal to 4

Step-by-step explanation:
41 out of 50 women surveyed liked perfume. what percentage of women did NOT like perfume
Answer:
18%
Step-by-step explanation:
Long Version: 41/50 = 0.82 and when you move the decimal two places right, you will get 82%. 100%-82%= 18%
Short Version: 9/50 people didn't like perfume. 9/50= 0.18 then you move the decimal two places right and it becomes 18%.
Answer
18% of women do not like perfume.
Step-by-step explanation:
First do 50-41, which is 9 to find out how many women don't like perfume. Next you find the percentage by doing 9/50 = 0.18 then you multiply 0.18 by 100. Finally you get 18%.

What are the two binomials for the expression x(x − 8) − 9(x − 8)?
The two binomials for the expression x(x − 8) − 9(x − 8) are (x - 8) and (x - 9).
What are the binomials expression ?
The expression x(x − 8) − 9(x − 8) can be simplified as follows:
x(x − 8) − 9(x − 8) = x² - 8x - 9x + 72
= x² - 17x + 72
To find the two binomials, we need to factor the expression [tex]x^2 - 17x + 72[/tex]. We can do this by finding two numbers that multiply to 72 and add to -17. Those numbers are -8 and -9. Therefore, we can write:
[tex]x^2 - 17x + 72 = (x - 8)(x - 9)[/tex]
Hence, the two binomials for the expression x(x − 8) − 9(x − 8) are (x - 8) and (x - 9).

36 cookies remain at this point.
Husband ate one sixth ; that's 6 cookies for him, 30 remain.
Answer:
Mrs. Jones has 30 cookies left.

1,006 in scientific notation
Answer:
1.006 × 10³
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.
Follow the steps below to see how 1,006 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 1,006
New Number: 1.006
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 0 0 6
Decimal Count: 1 2 3
There are 3 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10^b
a = 1.006
b = 3
Now the whole thing:
1.006 x 10³
Step 4
Check your work:
10³ = 1,000 x 1.006 = 1,006
Hope this helped.
