The Leungs sold a valuable painting for $55,000. This price is $1,000
more than twice the amount they originally paid for it. How much
did they originally pay?
A. $25,000 B. $27,000 C. $27,500 D. $28,000
Answer:
B. $27,000
Step-by-step explanation:
So 55,000 = 2x + 1,000
Simply for x
55,000 = 2x + 1,000
54,000 = 2x
x = 27,000

A local grocery store stocks packages of plain M&M's and packages of peanut M&M's. The ratio of the number of packages of peanut M&M's to the total number of packages on the shelf was 8 to 18.
Which number could be the number of packages of plain M&M's on the shelf?
Answer:
30
Step-by-step explanation: Because each batch has 18 total m&ms and there are 8 in each batch minus and then multiply.
The number of packages of plain M&M's on the shelf could be any multiples of 5.
What is Ratio?Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.
The ratio of a and b is denoted as a : b.
Given that,
Ratio of the number of packages of peanut M&M's to the total number of packages on the shelf = 8 : 18
That is, if there are total of 18 packages, 8 are peanut M&M's.
Number of plain M&M's out of 18 total packages = 18 - 8 = 10.
So,
Ratio of peanut M&M's to plain M&M's = 8 : 10
= 4 : 5
This indicates that, for a constant x,
Number of peanut M&M's = 4x
Number of plain M&M's = 5x
So the number of packages of plain M&M's on the shelf could only be the multiples of 5.
So it could be 5, 10, 15, 20, 25, 30, .......
Hence the number of plain M&M's on the shelf could be 5, 10, 15, 20, 25, 30, ......

Draw a two-dimensional representation of each prism. Then find the area of the entire surface of each prism
Answer:
Surface area of cuboid = 78 unit²
Step-by-step explanation:
Given diagram is a cuboid prism
Given:
Length of cuboid = 5 unit
Width of cuboid = 3 unit
Height of cuboid = 3 unit
Find:
Surface area of cuboid
Computation:
Surface area of cuboid = 2[lb + bh + hl]
Surface area of cuboid = 2[(5)(3) + (3)(3) + (3)(5)]
Surface area of cuboid = 2[15 + 9 + 15]
Surface area of cuboid = 2[39]
Surface area of cuboid = 78 unit²

What percentage of Americans would you predict wear glasses?
Answer: 64%
75% of adults use some sort of vision correction. About 64% of them wear eyeglasses, and about 11% wear contact lenses, either exclusively, or with glasses. Over half of all women and about 42% of men wear glasses.
63.8% of Americans are predicted to wear glasses
How to determine the percentage?The given parameters are:
Glasses = 638Sample size = 1000The percentage of Americans that wear glasses is calculated as:
Percentage = Glasses/Sample size
This gives
Percentage = 638/1000
Evaluate the quotient
Percentage = 0.638
Express as percentage
Percentage = 63.8%
Hence, 63.8% of Americans would wear glasses

The density of mercury is 13.5 times greater than the density of water. If you were to build a barometer that used water instead of mercury to record the standard pressure at sea level, what would be the height of that barometer? Assume that the mercury barometer is 76 centimeters, or 29.92 inches, long (this is the standard atmospheric pressure at sea level). View Available Hint(s) The density of mercury is 13.5 times greater than the density of water. If you were to build a barometer that used water instead of mercury to record the standard pressure at sea level, what would be the height of that barometer? Assume that the mercury barometer is 76 centimeters, or 29.92 inches, long (this is the standard atmospheric pressure at sea level). 110.29 centimeters (43.42 inches) 5.63 centimeters (2.21 inches) 89.5 centimeters (35.24 inches) 1026 centimeters (403.92 inches)
Answer:
h = 403.92in or 1026cm
Step-by-step explanation:
Given
Let x represent the density of mercury, and y the density of water.
[tex]y = 13.5x[/tex]
[tex]Mercury\ barometer =76cm[/tex] or [tex]Mercury\ barometer =29.92in[/tex]
Required
Determine the height of the barometer
At standard atmospheric pressure, the relationship between the mercury barometer and the height (h) of the barometer is:
[tex]h = 13.5 * Mercury\ barometer[/tex]
In centimeters, we have:
[tex]h = 13.5 * 76cm[/tex]
[tex]h = 1026cm[/tex]
In inches, we have:
[tex]h = 13.5 * 29.92in[/tex]
[tex]h = 403.92in[/tex]

[tex]Side\ 2 = 12cm[/tex]
[tex]\theta = 90^\circ[/tex]
Required [Missing from the question]
Draw the top of the cake
See attachment for reference.
From the attachment,
[tex]2cm = 1\ unit[/tex]
So:
[tex]Side\ 1 = 10cm[/tex]
[tex]Side\ 1 = 5 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 1 = 5 * 1unit[/tex]
[tex]Side\ 1 = 5\ units[/tex]
[tex]Side\ 2 = 12cm[/tex]
[tex]Side\ 2 = 6 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 2 = 6 * 1unit[/tex]
[tex]Side\ 2 = 6\ units[/tex]
This means that, the given side lengths will be represented by 5 units and 6 units on the grid, respectively.

What are Trignometric ratios ?The ratios of the sides of a right triangle are called trigonometric ratios.
Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
sin = Perpendicular/ Hypotenuse
Cos = Base / Hypotenuse
tan = Perpendicular/Base
In the figure attached with the answer we can see that in Triangle ABC ,
tan 50.1 = x / 5
5(tan 50.1) = x
Therefore x is approximately equal to 6.

the average can be calculated by adding the scores together and then dividing by the number of scores.
we can set up an equation:
let x = test score needed on next test
(72+72+80+x)/4 = 71
multiply both sides by 4
72+72+80+x = 284
add like terms
224+x=284
subtract 224 from both sides
x=60
she will need a 60 for her average to be 71
She needs to score a 60 to have a average score of 71,
72+72+80+60=284
284/4=71

(Student's Solution): "Factor the polynomial"
y^2-6y+9=y^2-2(y)(3)+3^2 = (y-3)(y+3)
Note: Please help, I have been working on this for like 4 days im so tired.
Answer:
See below.
Step-by-step explanation:
y^2 - 6y + 9 can be changed correctly into y^2 - 2(y)(3) + 3^2.
Up to here, it's correct.
The right side above shows a polynomial that is the square of a binomial.
It factors into (y - 3)^2.
The correct factorization is (y - 3)^2.
The incorrect factorization of the student's solution is the product of a sum and difference.
The product of a sum and a difference is the correct factorization for a difference of squares.
For example, y^2 - 9 is the same as y^2 - 3^2 and is a difference of squares.
It factors into (y + 3)(y - 3), a product of a sum and a difference.
