_______
2.5*10^-3 It's scientific notation and please explain your answer
Answer:
for the first one 9.407×10^−11
Step-by-step explanation:
Final answer:
To multiply numbers in scientific notation, multiply the coefficients and add the exponents. To divide, divide the coefficients and subtract the exponents. Ensure the final coefficient is between 1 and 10 for proper scientific notation.
Explanation:
To answer the question regarding scientific notation, I'll demonstrate the steps using the examples you provided. Remember that when multiplying numbers in scientific notation, you multiply the coefficients (the numbers in front) and then add the exponents.
(8.18 × 10^-6)(1.15 × 10^-5) = (8.18 × 1.15) × (10^-6 × 10^-5) = 9.407 × 10^-11. Since the coefficient 9.407 is between 1 and 10, this is in proper scientific notation.
To divide two numbers in scientific notation, you divide the coefficients and subtract the exponents: (1.15 × 10^-7) ÷ (2.5 × 10^-3) = (1.15 ÷ 2.5) × (10^-7 − (-3)) = 0.46 × 10^-4. Since the coefficient 0.46 is not between 1 and 10, we need to adjust it to proper scientific notation, which would be 4.6 × 10^-5.

The sale price of a swimming pool after 16.5% discount $1135.60. Find the original price of the pool
well, let's say the original price is "x", and thus is also the 100% price of the item, however the item is discounted by 16.5%, well 100% - 16.5% = 83.5%, so then the discounted price is really the 83.5% of the item, and we know that is $1135.60.
now, if 1135.60 is 83.5%, what is the 100% or namely "x"?
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 1135.60&83.5\\ x&100 \end{array}\implies \cfrac{1135.60}{x}=\cfrac{83.5}{100}\implies 113560 = 83.5x \\\\\\ \cfrac{113560}{83.5}=x\implies 1360 = x[/tex]
The original price of the swimming pool $1,360.
Original pool price=x
Percent discount=16.5% or 0.165
Sale price=$1135.60
Hence:
x-0.165(x)=$1135.60
x(1-0.165)=$1135.60
0.835x=$1135.60
Divide both side by 0.835x
x=$1135.60/0.835
x=$1,360
Inconclusion the original price of the swimming pool $1,360.

Step-by-step explanation:
Put 80 over 100
simplify to get 4/5x = 32
Multiply both sides by 5/4 (because you flip)
the fives cancel out and the fours
then you have x=5/4 x 32
four goes into 32 making it x=5 x 8

Answer: I think the answer is -x + y.
Step-by-step explanation:I think this is the answer because you first start off by distributing all the variables inside the parenthesis by the negative sign which would give you -x+2y-y. After that, you would have to subtract 2y-y because they share the same variable and you must have a SIMPLIFIED ANSWER. So with that said, your overall answer should be -x+y.

The elementary school students are putting on a play as a fundraiser. The student tickets cost $2.00 each and
the adult tickets cost $4 each. They sold 5 times as many student tickets as adult tickets. They made $140. How
many student and adult tickets were sold?
Answer:
850 for student and 850 for students
Step-by-step explanation:
Let student tickets sold be=x
and adult tickets sold=y
They sold 5 times as many student tickets as adult tickets.
i.e. x=5y
The student tickets cost $2.00 each and
the adult tickets cost $4 each.
They made $140.
i.e. 2x + 4y = 140
Dividing both sides by 6, we get
x + 2y = 70
or 5y + 2y= 70
i.e. 7y=70
i.e. y=10
x= 5y
⇒ x = 50
Hence, Student tickets sold= 50
and Adult tickets sold= 10

name the property that is shown by the following expression (9x3)x4=9x(3x4)
the associative property is used.
Which property is used in the expression?
The Associative property of multiplication says that (a × b) × c = a × (b × c),
so we can perform the multiplication in any order we want.
If you look at the expression:
(9x3)x4=9x(3x4)
The difference is that first we start with the product 9×3, and in the right side the first product we need to solve is 3×4, so the associative property is used.

The estimated answer to a multiplication problem is 800,000. Which of the following expressions could result in this answer? Explain how you know.
8,146 x 12
81,467 x 121
8,146 x 121
81,477 x 1,217
Answer:
8,146 x 121
Step-by-step explanation:
This is a problem in which you need to measure your understading of "orders of magnitude."
If the estimated answer is [tex]800000[/tex] that means that we are looking at a multiplication in the "order of" [tex]8*10^5[/tex]
You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have [tex]8146*12[/tex] that would be "of the order of" [tex]8*10^3[/tex] times [tex]10^1[/tex]. So the whole multiplication would "of the order of" [tex]8*10^4[/tex] or near [tex]80000[/tex]
The correct answer, 8,146 x 121, is because it's "of the order of" [tex]8*10^3[/tex] times [tex]10^2[/tex] and the gives us the [tex]8*10^5[/tex] we need.

A carpenter goes through 2 2 ⁄6 boxes of nails finishing 3 1 ⁄4 rooves. How much would he use finishing 2 rooves?
Answer:
1 17/39 boxes.
Step-by-step explanation:
3 1/4 rooves requires 2 2/6 boxes
So 2 rooves require 2 * 2 2/6 / 3 1/4 boxes.
= 2 * 14/6 / 13/4
= 28/6 * 4/13
= 56/39
= 1 17/39 boxes.
The question involves calculation of usage rate per roof by dividing the total boxes used by the number of rooves completed and then applying that rate to determine number of boxes needed for 2 rooves.
Explanation:The question asks how many boxes of nails a carpenter would use for 2 rooves if he goes through 2 2/6 boxes to complete 3 1/4 rooves. To find out the number of boxes needed for 2 rooves, we need to calculate the rate of nail box usage per roof and then apply that rate to 2 rooves.
First, we simplify 2 2/6 to a mixed number: 2 1/3.
Then we divide the number of boxes by the number of rooves to get the usage rate per roof:
2 1/3 boxes ÷ 3 1/4 rooves = usage rate per roof.
Once we get the usage rate, we multiply it by 2 to find the boxes needed for 2 rooves.
This process involves converting mixed numbers to improper fractions, performing division, and then multiplication.

The equation that can be solved using the graph is x^2 - 2x + 1 = 0.
Explanation:The equation that could be solved using the graph above is x2 - 2x + 1 = 0. This is because the graph intersects the x-axis at the point where y=0, and this represents the solutions to the equation.
If we solve the equation x2 - 2x + 1 = 0 using factoring or the quadratic formula, we would find that the solutions are x=1 and x=1. These are the same x-values where the graph intersects the x-axis on the graph provided.
