The rectangle has an area of x^2 - 9 square meters and a width of x - 3 meters.
What expression represents the length of the rectangle?
Answer:
Length = x + 3 meters
Step-by-step explanation:
Expression for the area of the rectangle = [tex]x^2 - 9 = (x + 3)(x - 3) m[/tex]
Expression for width of rectangle = ([tex]x - 3[/tex]) m
Area of a rectangle = [tex]Length \times Width[/tex]
⇒ Expression for length of rectangle = [tex]\frac{Area}{Width} = \frac{(x + 3)(x - 3)}{(x - 3)} = (x + 3) m[/tex]

Write the inequality shown by the graph.
Answer: A
Step-by-step explanation:
The line and dots are closed circle, so B and D would not be the answer.
The line have passed through the point (-6,4) and (0,2); we uses to find the slope.
slope = m = (y2 - y1)/(x2 - x1) = (2 - 4)/(0 - (-6)) = -2 / 6 = -1/3
we plug in slope to the linear equation in form of y = mx + b, where m is the slope, and b is the y- intercept.
y = -1/3x + 2
So the answer is A.

On Saturday, a local hamburger shop sold a combined total of 261 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Saturday?
Answer:
134 hamburgers
Step-by-step explanation:
Let H = # of hamburgers
# of cheeseburgers = 2H
H + 2H = 402
3H = 402
H = 402/3
H = 134

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, ......

3. Find the area of a semicircle with a diameter of
30 inches.
Answer:
Answer:
Area of a CIRCLE with radius of 3 inches is
PI * radius^2 =
3.14159265 * 3^2 =
28.27433385 square inches.
Since we are dealing with a SEMI-CIRCLE, we divide that by 2 and get:
14.137166925 square inches which rounds to about
14.14 square inches
Step-by-step explanation:
Answer: 30pi^2 divided by 2
Explanation:
To find the area of a circle, it is pi x radius ^2
Since it is a semicircle 30 is the radius.
pi x radius ^ 2 = 30pi^2
the area would be 30pi^2 divided by 2

jessica made $234 for 13 hours of work. At the same rate, how many hours would she have to work to make $162?
Answer: 9 hours
We would get:
1 hour of work = $18
162 divided by 18 = 9
So she would have to work 9 hours
Answer:
9 hours
Step-by-step explanation:
Step One: A rate is the same thing as ratio. This just means that there is a proportion. For example, for every 3 dogs, there are 4 cats. This would mean that for 6 dogs there are 8 cats, and so on.
Step Two: Okay, because these numbers are larger, it is easiest to scale it back to one. The proportion or rate given is $234/13 hours. We would divide by 13 to get it to 1: $18/1 hour. The proportion is usually a decimal, but these numbers happen to divide nicely.
Step Three: Now, we can do 162/18 to see what the scale is, or how much times larger it is: 162/18=9.
Step Four: Lastly, just do 1 times 9, which tells it is 9 hours. To check the work, make sure 9 is less than the original proportion; it should take less time to make less money. 9 is less than 13, so this is the answer!

An insurance policy sells for $600. Based on past data, an average of 1 in 50 policyholders will file a $5,000 claim, and average of 1 in 100 policyholders will file a $10,000 claim, and an average of 1 in 200 policyholders will file a $30,000 claim. What is the expected value per policy sold?
Answer:
$250
Step-by-step explanation:
Calculation to determine the expected value per policy sold
Expected value per policy sold =$600-(1/50)*$5,000-(1/100)*$10,000-(1/200)*$30,000
Expected value per policy sold =$600-$100-$100-$150
Expected value per policy sold =$250
Therefore the expected value per policy sold will be $250

Jaden is playing hide-and-seek with Henry and Valentina. Henry is hiding 12 meters south of
Jaden, and Valentina is hiding due east of Henry. If Jaden is 20 meters from Valentina, how many meters far apart are Henry and Valentina?
Answer:
Henry and Valencia are 16 m apart.
Step-by-step explanation:
A sketch to this question shows that their distance apart forms a right angled triangle. So then, we can apply the Pythagoras theorem.
Let the distance between Henry and Valencia be represented by x, so that;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]
[tex]20^{2}[/tex] = [tex]x^{2}[/tex] + [tex]12^{2}[/tex]
400 = [tex]x^{2}[/tex] + 144
[tex]x^{2}[/tex] = 400 - 144
= 256
x = [tex]\sqrt{256}[/tex]
= 16
x = 16 m
Therefore, Henry and Valentia are 16 meters apart.
