Suppose you invested $500 in K-Mart stock in October
of 2001. Each month the stock lost 2% of its value.
How much was the stock worth in October of 2002?
(HINT: The loss is per MONTH.)
Answer:
$380
Step-by-step explanation:
Amount invested in October 2001 = $500
If 2% is lost on stock each month, amount lost every month will be 2% of $500
= 2/100×$500
= $10
In order to know how much the stock will cost by October 2002, we need to know the number of month there is between October 2001 and October 2002.
The number of months within this period is 12months
If $10 is lost per month, the total stock lost for 12months will be
$10×12 = $120
Stock worth by October 2002 = Money invested - Total stock loss
Stock worth by October 2002 = $500-$120
= $380

Answer:
m<U=95
m<W=85
m<T=119
m<V=61
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so add up <U and <W to equal 180.
z=6
To find <V, subtract <T from 180.
Use the elimination method to solve the system of equations. Choose the correct ordered pair.
x + y = 9
x – y = 7
# Choice
A. (12, –3)
B. (8, 1)
C. (7, 0)
D. (16, –7)
Step-by-step explanation:
x + y = 9 ......... equation 1
x - y = 7 ............equation 2
Now solving both equations
x + y = 9
x - y = 7
2x = 16
Therefore x = 8
Now putting x = 8 in equation 1
8 + y = 9
Therefore y = 1
Here B (8 , 1) is your answer

What is the measure of Angle A? (picture included)
Answer:
19.4
Step-by-step explanation:
10x-14=180
Answer:
19.4
Step-by-step explanation:
we know a + b + c = 180 so:
x + 5x + 4x -14 = 180
10x = 180 + 14
10x = 194
x = 19.4 degrees

A triangle has an area of 70 square inches. The height of the triangle is 8 inches. Write and solve an equation to find the length of the base of the raingle
Answer:
70 = 1/2 b *8
17.5 inches =b
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
We know the area and the height
70 = 1/2 b *8
70 = 4b
Divide each side by 4
70/4 = 4b/4
17.5 =b

The volume of a cube is V=s3 , where s is the length of one edge of the cube. What is the edge length s for each cube?
look at the picture for the answer choices:)
Answer:
s = [tex]\sqrt[3]{999} }[/tex]
Step-by-step explanation:
V = s^3
Plug in the given volume.
999 = s^3
Take the third root of both sides to cancel out the ^3.
[tex]\sqrt[3]{999} }[/tex] = s
Answer:
A) s = ∛999 in.
The graph shows the salaries of 23 employees at a small company. Each bar spans a width of $50,000 and the height shows the number of people whose salaries fall into that interval. Which inequality correctly describes the relationship between the mean and the median? A) mean < median < $250,000 B) median < mean < $250,000 C) median < $250,000 < mean D) mean < $250,000 < median
Answer:
b
Step-by-step explanation:
The mean is heavily influenced by the outlier salary of $5,000,000, making it much higher than the stable median of $30,000. The correct inequality reflecting the relationship between the mean and the median salaries in this skewed distribution is median < mean < $250,000. The correct choice is option B) median < mean < $250,000.
Given the information about the salaries, the distribution has a significant skew due to the presence of an outlier. This outlier is the one employee earning $5,000,000, which is vastly different from the rest of the group who earn $30,000. When an outlier is present, the mean will be greatly affected, whereas the median will remain a more stable measure of central tendency.
The median salary in this scenario would be $30,000, as 49 out of 50 salaries are at this amount, and thus the middle value of the ranked list would not be impacted by the outlier. However, the mean would be significantly higher because it includes the $5,000,000 salary in the calculation. Since the question describes an inequality relationship between the mean and median, the correct answer is that the median is less than the mean, but both the median and the mean are less than $250,000, which leads to the correct inequality: B) median < mean < $250,000.

Find the height of the parallelogram in which A= 7.5 m^2
Step-by-step explanation:
Given the area of the Parallelogram
[tex]A=\:7.5\:m^2[/tex]
The area of a parallelogram is defined as the multiplication of its base and height.so
A = base × height
Plugging A = 7.5 m² in above equation
7.5 m² = base × height
height = base ÷ 7.5 m²
Therefore, height of the parallelogram with area 7.5 m² is : base ÷ 7.5 m²

what adds to be the bottom number but also multiplies to be the top 15 8
Final Answer:
It's likely that the student is concentrating on a factoring problem. The two numbers are 5 and 3, which when multiplied together equal 8 (the small number) and 15 (the big number).
Explanation:
It appears that you are looking for two numbers that sum up to 8 and multiply by 15, since the bottom number is 8 and the top number is 15.In this case, the appropriate responses are 5 and 3. Specifically, this is why: the sum equals 5 + 3 = 8.15 is the result of multiplying 5 by 3.
So, 5 and 3 are the numbers you're looking for.

Which pair of angles is classified in the same category according to the angle measure?
Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll help you in a general way. Let's mention some categories:
1. Category of congruence:
Angles are congruent if they have the same measure. So if we have two angles:
[tex]\angle A=30^{\circ} \\ \\ \angle B=30^{\circ}[/tex]
Then they are congruent. In other words:
[tex]\angle A \cong \angle B[/tex]
1. Category of complementary angles:
Two angles are complementary if they add up to 90 degrees. So if we have:
[tex]\angle A=30^{\circ} \\ \\ \angle B=60^{\circ}[/tex]
They are complementary because:
[tex]\angle A+ \angle B=30^{\circ}+60^{\circ}=90^{\circ}[/tex]
1. Category of supplementary angles:
Two angles are supplementary if they add up to 180 degrees. So if we have:
[tex]\angle A=110^{\circ} \\ \\ \angle B=70^{\circ}[/tex]
They are supplementary because:
[tex]\angle A+ \angle B=110^{\circ}+70^{\circ}=180^{\circ}[/tex]

The difference between two numbers is 55. If the smaller number is increased by 15 and the bigger number is decreased by 15. What will be the new difference?
Answer:
25
Step-by-step explanation:
Lets say the numbers are 100 and 45.
If the smaller number is increased by 15
45+15=60
the bigger number is decreased by 15
100-15= 85
What will be the new difference?
85-60= 25
The new difference will be 25.
Given that,
The difference between the two numbers is 55.
If the smaller number is increased by 15 and the bigger number is decreased by 15.
We have to determine,
What will be a new difference?
According to the question,
Let the first number be x,
And the second number be y.
The difference between the two numbers is 55.
x + y = 55
The smaller number is increased by 15,
Then,
The number is,
45 + 15 = 60
And the bigger number is decreased by 15,
Then,
The number is,
100 - 15 = 85
Therefore,
The new difference between the new number is,
85 - 60 = 25
Hence, The new difference will be 25.
