I NEED HELP PLEASE!!! An investor has an account with stock from two different companies. Last year,
her
stock in Company A was worth $2300 and her stock in Company B was worth $3080.
The stock in Company A has decreased 9% since last year and the stock in Company
B has decreased 25%. What was the total percentage decrease in the investor's stock
account? Round your answer to the nearest tenth (if necessary).
Answers
Answer:
81.8%
Step-by-step explanation:
Last year:
Company A stock + Company B stock = total amount of stock:
$2300 + $3080 = $5380
This year:
Company A stock: 2300 - (2300*0.09) = 2093
Company B stock: 3080 - (3080*0.25) = 2310
Company A stock + Company B stock = total amount of stock:
$2093 + $2310 = $4403
Total amount of decrease from last year:
[tex]\frac{4403}{5380} * 100 = 81.8[/tex] percent

Step-by-step explanation:
So first, you find the area of a rectangle, which would be 15 * 30 = 450. Next, find the area of the semicircle by doing [tex]\pi *r^2 / 2[/tex] (you have to divide by 2 because it's only have a circle).
The radius is half of 15, so 15 / 2 = 7.5. This would be:
[tex]\pi * 7.5^2 / 2[/tex]
[tex]=\pi * 56.25 /2[/tex]
[tex]=28.125\pi[/tex]
[tex]=28.125*3.14=88.3125[/tex]
The last step is to add 450 + 88.3125 = about 538.3 m^2

Find the missing side length. Tell if the side lengths form a Pythagorean triple. Explain.
Answers
The length of the missing side of the triangle is 15.
How to calculate the length of the side of the triangle?To calculate the length of the side of the triangle we must use the Pythagorean theorem:
b = [tex]\sqrt[]{(a^{2})-(b^{2} }[/tex]
In this formula we can replace the value of a and c with the distances of the other sides of the triangle.
b = [tex]\sqrt[]{(25^{2}) - (20^{2}) }[/tex]
b = [tex]\sqrt[]{(625) - (400)}[/tex]
b = [tex]\sqrt[]{225}[/tex]
b = 15
According to the above, the length of side b is 15.

Answers
X=-42
Explanation:
1-2x-9=4•19
-8-2x=76
-2x=76+8
-2x=84
X=-42
Answer:
x = 42
Step-by-step explanation:
1 - (2x + 9) = 4(21 - 2)
Distributive property ( multiply whatever is in the parenthesis by (-) for the first one, and (4) for the second one)
1 - * 2x + - * 9 = 4 * 21 - 4 * 2
1 - 2x - 9 = 84 - 8
Combine like terms
-8 - 2x = 76
Add 8 on both sides
-8 + 8 - 2x = 76 + 8
2x = 84
Divide by 2 on both sides to isolate the variable
2x/2 = 84/2
x = 42
