An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $1700 and her stock in Company B was worth $500. The stock in Company A has increased 20% since last year and the stock in Company B has increased 12%. What was the total percentage increase in the investor's stock account?
Answer:
All together she had a 18.1818182% raise but 18% raise rounded.
Step-by-step explanation:
First you need to find how much each stock increased.
So:
1700 to 2040
500 to 560
Add them.
1700 + 500 = 2200
2040 + 560 = 2600
Then find the raise. You can usally just find the amount for each percent or find the over all raise.
1% of 2200 is 22
400/22 = 18.18
find the distance between each pair of points E(-1, 0),F(12, 0)
Answer:
The answer is
[tex]13 \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
E(-1, 0) and F(12, 0)
The distance between them is
[tex] |EF| = \sqrt{ ({ - 1 - 12})^{2} + ({0 - 0})^{2} } \\ = \sqrt{ ({ - 13})^{2} } \\ = \sqrt{169} [/tex]We have the final answer as
[tex]|EF| = 13 \: \: units[/tex]Hope this helps you
The division property of 5x - 10 = 0
Answer:
x=2
Step-by-step explanation:
5×-10=0
5×=10
so you divide both sides by 5
Answer:
x=2
Step-by-step explanation:
The coordinates of point A are 400 units of X and 40 units of Y. The coordinates of point B are 480 units of X and 60 units of Y. With X on the horizontal axis and Y on the vertical axis, the slope of the line between points A and B is
Answer:
The slope of the line between points A and B is 0.25
Step-by-step explanation:
Here in this question, we simply aim at calculating the slope of the line between two given points;
The points in question are;
A(400,40) and B(480,60)
Mathematically, the slope of the line can be calculated using the formula:
slope = (y2-y1)/(x2-x1)
Where ;
x1 = 400
y1 = 40
x2 = 480
y2 = 60
Substituting the values, we have;
slope = (60-40)/(480-400) = 20/80 = 1/4 = 0.25
16. Peter works part time for 3 hours every day and Cindy works part time for 2 hours every day. a. If both of them get $4.50 an hour, write an inequality to compare Peter's and Cindy's earnings.
Answer:
Inequality:
$14.5 > $9
OR
Peter's earnings > Cindy's earnings
Step-by-step explanation:
Number of hours Peter works every day = 3 hours
Number of hours Cindy works every day = 2 hours
Earnings per hour for both of them = $4.50
Total daily Earnings for Peter = Number of hours worked by Peter multiplied by hourly earnings of Peter
Total daily Earnings for Peter = 3 \times $4.50 = $13.5
Total daily Earnings for Cindy = Number of hours worked by Cindy multiplied by hourly earnings of Cindy
Total daily Earnings for Cindy = 2 \times $4.50 = $9
Comparing the daily earnings of Peter and Cindy, we can see that Earnings for Peter is greater than that of Cindy.
Inequality:
$14.5 > $9
OR
Peter's earnings > Cindy's earnings

state any restrictions on the variable(s) if they exist.
PLEASE HELP DUE TODAYY
Restrictions are that 'a' and 'b' cannot be zero. We could write [tex]a \ne 0[/tex] and [tex]b \ne 0[/tex] as shorthand.
The restrictions are put in place to ensure that you can't divide by zero.
=========================================
Explanation:
The coefficients -12 and 4 divide to -12/4 = -3 which is the coefficient for the answer in the numerator.
The 'a' terms divide to (a^3)/(a^2) = a^(3-2) = a^1 = a. We subtract the exponents to simplify.
The b terms are handled in a similar manner to get (b^5)/(b^7) = b^(5-7) = b^(-2) = 1/(b^2)
Putting all three results together has us end up with (-3a)/(b^2) where neither 'a' nor b are zero to prevent a division by zero error. We cannot have 0 in the denominator.
0.5% of a is 3 then what is a?
Answer:
a = 600Step-by-step explanation:
0.5%a = 3
×10 ×10
5%a = 30
×20 ×20
100%a = 600
a = 600
Find the measures of the angles of a triangle if the measure of one angle is twice the measure of a second angle and the third angle measures 3 times the second angle decreased by 48.
Answer:
38°, 66° and 76°Step-by-step explanation:
A triangle consists of 3 angles and sides. The sum of the angles in a triangle is 180°. Let the angle be <A, <B and <C.
<A + <B + <C = 180° ...... 1
If the measure of one angle is twice the measure of a second angle then
<A = 2<B ...... 2
Also if the third angle measures 3 times the second angle decreased by 48, this is expressed as <C = 3<B-48............ 3
Substituting equations 2 and 3 into 1 will give;
(2<B) + <B + (3<B-48) = 180°
6<B- 48 = 180°
add 48 to both sides
6<B-48+48 = 180+48
6<B = 228
<B = 228/6
<B =38°
To get the other angles of the triangle;
Since <A = 2<B from equation 2;
<A = 2(38)
<A = 76°
Also <C = 3<B-48 from equation 3;
<C = 3(38)-48
<C = 114-48
<C = 66°
Hence the measures of the angles of the triangle are 38°, 66° and 76°
f(x)=8x^2 -800 Enter the solutions from least to greatest.
Answer:
x = -10, 10
Step-by-step explanation:
Step 1: Write out function
f(x) = 8x² - 800
Step 2: Set equal to 0
0 = 8x² - 800
Step 3: Add 800 on both sides
800 = 8x²
Step 4: Divide both sides by 8
x² = 100
Step 5: Take square root on both sides
x = ±10
Step 6: Arrange
-10 < 10
So x = -10, 10

11m - (6m - 5) = 25 solve for m please
Answer:
m = 4Step-by-step explanation:
[tex]11m - (6m - 5) = 25\\[/tex]
Use - to open the bracket
[tex]-(6m-5)= -6m+5[/tex]
[tex]11m-6m+5=25\\[/tex]
Collect like terms and simplify
[tex]11m-6m=25-5\\5m = 20[/tex]
Divide both sides of the equation by 5
[tex]\frac{5m}{5} = \frac{20}{5} \\\\m = 4[/tex]
7(3y-5) -2 (10+4y)
-distributive property-
Answer:
13y - 55
Step-by-step explanation:
Given
7(3y - 5) - 2(10 + 4y) ← distribute both parenthesis
= 21y - 35 - 20 - 8y ← collect like terms
= 13y - 55
Answer:
When using the distributive property, we can operate parenthesis:
[tex]a*(b+c)=ab + ac[/tex]
So, in our case:
[tex]7(3y-5) -2(10+4y)[/tex]
[tex]7*3y+7*(-5) - 2*10-2*4y[/tex]
[tex]21y -35 - 20 - 8y[/tex]
[tex]=13y - 55[/tex]
So now we know the result is 13y - 55

A rectangular garden is fenced on all sides with 128 feet of fencing. The garden is 4 feet longer than it is wide. Find the length and width of the garden.
Answer:
Length = 34 and Width = 30
Step-by-step explanation:
This is a simple system of equation that is mainly solved using substitution, so keep in mind the following key points:
Rectangle's Perimeter is 128 ft."the garden is 4 feet longer than it is wide," this simply means that the Length is 4 feet longer than the Width: which algebraically translates to [tex]L = 4 + W[/tex]Perimeter formula for Rectangle is [tex]P = 2(L+W)[/tex]First, we find the Width by plugging the given values in the formula:
[tex]128 = 2((4 + W) + W)\\128 = 8 +2W + 2W\\120 = 2W + 2W\\120 = 4W\\W = \frac{120}{4}\\\ W = 30[/tex]
All we did here was substituting 4 + W for L to find the Width.
Now, to find the Length we plug in the value of W and solve for L:
[tex]128 = 2(L + 30)\\\frac{128}{2} = (L + 30)\\64 = L + 30\\64 - 30 = L\\L = 34[/tex]
