An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Investment in Company A by investor = $6100
Investment in Company B by investor = $6480
The decrease in value of the stock of company A is 2%
The decrease in value of the stock of company B is 10%
Value of wealth that investor lost in company A = 6100× 2/100
= 61×2
= $122
The decline in the value of the stock of company B = 6480×10/100
= 648×1/1
= $648
The total decline in the wealth of the investor= 122+648
= $770
The combined wealth of investor in both companies= 6100+6480
= $12580
Percentage of decline in the stock account of investor= 770×100/12580
= 77000/12580
= 6.1%
The total percentage decline in investor's stock account is 6.1%

What is the area of Z?
Answer:
t = 5 kilometers
Step-by-step explanation:
From the given figure,
Perimeter = 18 kilometers
Now, the formula for perimeter of a rectangle = 2(l + b)
Where,
'l' is the length of the rectangle
and
'b' is the breadth of the rectangle.
Since length is the longest side of a rectangle, therefore from the given figure
=> l = t kilometers
and
=> b = 4 kilometers
Substituting values in the formula,
18 = 2(t + 4)
=> 18/2 = t + 4
=> 9 = t + 4
=> 9 - 4 = t
=> t = 5 kilometers
Answer:
5 km
Step-by-step explanation:
We know that the perimeter of this rectangle is 18km.
We also know that 1 side is 4km.
Given the perimeter formula:
\(P=2(l+w)\)
We can substitute our given values:
18=2(4+w)
Solve the right side
18=8+2w
subtract 8 from both sides
10=2w
divide both sides by 2
5=w
This means that z, the width, is 5 km.

Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16

the temperature at 2 pm is 27° at 2 am the temperature has fallen to -4° what is the total difference in temperature from 2:00 pm to 2:00 am???
Answer:
The temperature difference is equal to 27-(-4)=31.
Step-by-step explanation:
Answer:
31° .
Step-by-step explanation:
we need to calculate the temperature difference between 2 pm and 2 am we can get the difference by subtracting the temperature at 2 am from the temperature at 2 pm
the temperature at 2 pm is 27°
the temperature at 2 am is -4°
the temperature difference between 2 pm and 2 am is:
27° - (-4)° = 31°
If the Volume of this barrel is 600,000 cm^3, what is the height of the barrel?
Since Volume = Area of the base * height, you can "undo" the formula to find a missing value. If you know the volume, then you find the height by dividing the Volume by the Area of the base. Remember that height is written with units, not units^2 or units^3.
For a school project, Derek is investigating cell phone use in his hometown, Somerville. So far, he has found that the residents of Somerville used their cell phones for 11,609 minutes this year. Compared to last year, that is 30% more. For how many minutes did the residents of Somerville use their cell phones last year?
Answer:
Therefore, the residents of Somerville used their cell phones for approximately 8,930 minutes last year.
Step-by-step explanation:
To find out how many minutes the residents of Somerville used their cell phones last year, we can use the information given that this year's cell phone usage is 30% more than last year's.
Let's assume the cell phone usage last year was represented by the variable "x" (in minutes).
According to the information given, this year's cell phone usage is 30% more than last year's, so we can express this as:
x + 0.3x = 11609
Combining like terms, we have:
1.3x = 11609
To isolate the variable, we divide both sides of the equation by 1.3:
x = 11609 / 1.3
Simplifying the calculation, we find:
x ≈ 8930
Answer:
Therefore, the residents of Somerville used their cell phones for approximately 8,930 minutes last year.
Step-by-step explanation:
To find out how many minutes the residents of Somerville used their cell phones last year, we can use the information given that this year's cell phone usage is 30% more than last year's.

The histogram shows the number of points scored by a basketball team for one season. A histogram titled points scored in one season shows the number of games in which a certain number of points were scored. The data is as follows. 69 to 76 points: 3 games. 77 to 84 points: 6 games. 85 to 92 points: 8 games. 93 to 100 points: 1 game. According to the histogram, in what percentage of games did the team score between 77 and 92 points? Enter your answer in the box. Round your answer to the nearest percent.
Percentage of games the team scored between 77 and 92 is 77.7% .
Given data from the histogram shows the number of games that are played in the range of 77 - 92.
Total number of games played = 18
Number of games played in the range 77 - 92 = 14
Percentage of games played in the range 77-92 = (Number of games played in the range 77 - 92) / (Total number of games played) × 100
Percentage = (14)/(18) × 100
= 77.7% .
Hence the number of games played in the given range is 77.7%.

0.5% of w is 12 is what they are asking
0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is
\(12 = 0.005 \times w\)
Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite
\(w = \frac{12}{0.005} = 2400\)
