Answer:
$50,000 in stocks
$40,000 in bonds
$25,000 in CDs
Step-by-step explanation:
Let c represent the amount invested in CDs. Then the amount invested in bonds is (c+15000) and the amount invested in stocks is (115000 -c -(c+15000)) = (100000 -2c). The total interest earned is ...
0.04c +0.053(c +15000) +0.062(100,000 -2c) = 6220
-0.031c +795 +6200 = 6220
-0.031c = -775 . . . . . . . . . . . . . . . subtract the left-side constants
c = 25000 . . . . . . . . . . divide by the coefficient of c
c+15000 = 40000 . . . . bonds
100000 -2c = 50000 . . . . . stocks

Answer:
x^2 + 7x- 3/x - 3/x^2 -16
Step-by-step explanation:
Key: ( ^ ) means exponent
= x^2 + 2x- 3/x -2x^2 + 5x- 3/x^2 -16
= x^2 - 2x^2 + 2x+5x - 3/x- 3/x^2 -16
= x^2 - 2x^2 = -x^2
= -x^2 + 2x + 5x- 3/x- 3/x^2-16
As you see you add 2x and the 5x and got 7x
= Answer : x^2 + 7x- 3/x - 3/x^2 -16

the perimeter of rectangle is 2x² + 4x - 4y. its length is (2x - 3y). find the breadth of rectangle
plz help fast plz plz
Perimeter = 2 (l + b)
2x² + 4x - 4y = 2 {(2x - 3y) + b}
2x² + 4x - 4y = (4x - 6y) + 2b
2x² + 4x - 4y - (4x - 6y) = 2b
2x² + 4x - 4y - 4x + 6y = 2b
2x² + 2y = 2b
(2x² + 2y)/2 = b
x² + y = b
Breadth = x² + y

Answer:
2/3Step-by-step explanation:
If we want to find the slope, the most easiest way to find the slope is to use 'Rise/Run'. Two points are given, lets use those points and find the slope.
=> We see that the rise is 2. So 2 will be our numerator,
=> We can also see that the run is 3. So 3 will be our denominator.
What do we get?
We get 2/3 as our slope. Therefore, B is our answer. Hoped I helped.

A line that passes trough the point (7,3) with slope of -1 ( answer plesse I need help )
Answer:
Slope-Intercept Form:
The equation of a line in slope-intercept form is y=mx+b. Since we know that the slope is -1, the equation so far is y=-x+b. To find the value of b, substitute in the given point.
3=-7+b
Add 7 to both sides.
10=b
The equation of the line is slope intercept form is y=-x-10.
Point-Slope Form:
The equation of a line in point-slope form is y-y1=m(x-x1). Substituting in the given point and slope, the equation is y-3=-(x-7).
Hope this helps! :)
Answer:
y= -x + 10
Step-by-step explanation:
3 = -1(7) + b
3 = -7 + b
10 = b
Since the slope is -1, that means it's just -x
So y = -x + 10

1428 rounded to the nearest thousandth
Answer:
1428- one is in the thousandth place
the number beside is lower than five so drop it and add zero to the end
1000 -is now your answer
Step-by-step explanation:
hope this helps if not then sorry goodluck and bye
The number 1428 to the nearest thousand is 1000.
When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.
1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Here, the question said the nearest thousand, so I had to look at the value in the hundred places which is 4 and less than 5.
Hence round the number down.
So, 1428 to the nearest thousand is 1000.

In this exercise we have to use the knowledge of polygon areas to calculate the area of each of the informed objects, so we have to:
1) [tex]h = 19.1 in[/tex]
2) [tex]a = 6.7 ft[/tex]
3) [tex]e = 2.3 m[/tex]
4) [tex]y = 9.8 cm[/tex]
5) [tex]o = 71.6 ft[/tex]
6) [tex]e = 15.3 in[/tex]
7) [tex]y = 41.5 m[/tex]
8) [tex]o = 13.7 cm[/tex]
9) [tex]p = 18.5 ft[/tex]
10) [tex]s = 25.8 in[/tex]
11) [tex]b = 61.3 m[/tex]
12) [tex]n = 6.2 cm[/tex]
Then each of the figures will have its own area formula that corresponds to:
1) For the rectangle we find that:
[tex]14/11 = h/15\\h = 19.1 in[/tex]
2) For the rectangle we find that:
[tex]5/a = 9/12\\a = 6.7 ft[/tex]
3)For the rectangle we find that:
[tex]3.7/6.5 = e/4.0\\e = 2.3 m[/tex]
4) For the triangle we find that:
[tex]10/8 = s/13\\s = 16.3 cm\\6/8 = y/13\\y = 9.8 cm[/tex]
5) For the triangle we find that:
[tex]n/70 = 53/88\\n = 42.2 ft\\o/70 = 90/88\\o = 71.6 ft[/tex]
6) For the triangle we find that:
[tex]t/9.1 = 11.2/5.7\\t = 17.9 in\\e/9.1 = 9.6/5.7\\e = 15.3 in[/tex]
7) For the triangle we find that:
[tex]u/48 = 43/74\\u = 27.9 m\\y/48 = 64/74\\y = 41.5 m[/tex]
8) For the triangle we find that:
[tex]6.2/11.8 = t/10.1\\t = 5.3 cm\\o/10.1 = 16.0/11.8\\o = 13.7 cm[/tex]
9) For the triangle we find that:
[tex]30/p = 13/8\\p = 18.5 ft[/tex]
10) For the trapezoid we find that:
[tex]20/s = 12/15.5\\s = 25.8 in[/tex]
11)For the triangle we find that:
[tex]l/46 = 125/75\\l = 76.7 m\\b/46 = 100/75\\b = 61.3 m[/tex]
12)For the triangle we find that:
[tex]5.1/4.3 = r/9.8\\r = 11.6 cm\\n/9.8 = 2.7/4.3\\n = 6.2 cm[/tex]

Find the median and mean number of hours for these students.
If necessary, round your answers to the nearest tenth.
Step-by-step explanation:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
so, the mean value is
(10+10+18+18+10+5+12+13)/8 = 96/8 = 12
the median is first not clear when ordering the data set, as we have an even number of elements.
5 10 10 10 12 13 18 18
so, we have to take the mean or average between the 2 middle numbers : 10 and 12.
(10+12)/2 = 22/2 = 11
the median is 11.

express the function graphed on the axes below as piecewise function
for x<-4
for x>2
Answer:
<--------o o------------->
-4 2
Step-by-step explanation:
Because the sign in the inequalities is only greater than/ less than (not equal to), we know that there is an open dot on x=-4 and on x=2.
From there, we shade the area on the graph that is true to the function. So, we can test points.
First we will test x=-5
-5<-4 --> this is true, so we will shade to the left of x=-4
Now test x=0
0<-4 --> this is false
0>2 --> this is also false, so the area between the two open dots will not be shaded
Now test x=3
3>2 --> this is true, so we will shade to the right of x=3

Answer:
1. 2 hours
2. 25cm
3. 6.84
Step-by-step explanation:
120÷3=40
4800÷40=120 so 2 hours
for the second one just divide 50 in half
for 3 just do $1.14×6
Answer:
1. 120 min
2. 25 cm
3. $6.84
Step-by-step explanation:
1. 120 words : 3min
multiply each side by 40 because 120 words times 4 is 4800 words
4800 words : 120min
2. 2 : 1 = length : width
multiply each side by 25 because 2 times 25 is 50 cm
50 cm : 25 cm
3. $1.14 : 100 grams
multiply each side by 6 because 100 grams times 6 is 600 grams
$6.84 : 600 grams

Which function has the greater rate of change? What is that value?
Answer:
To find the rate of change you use the formula, Y2-Y1/X2-X1.
Function A:
You can substitute in any two points. The points I will use are (0,0) and (1,1).
1-0/1-0
1/1
1
The rate of change for Function A is 1.
Function B:
The points I will use are (2,1) and (4,2).
2-1/4-2
1/2
The rate of change for Function B is 1/2.
Since 1 is larger than 1/2, Function A has a larger rate of change. The value is 1.
Hope this helps! :)

A t-shirt increased in price by 1/4. After the increase, it was priced at £65. What was the original price of the t-shirt?
Answer:
52
Step-by-step explanation:
Given:
1/4
Price at 65
Solution:
Let x be the original price
Based on the given conditions, formulate: [tex]x[/tex] ×[tex](1+\frac{1}{4} )=65[/tex]
Apply Multiplicative Distribution Law: [tex]x+\frac{x}{4} =65[/tex]
Multiply both sides of the equation by the common denominator: [tex]x[/tex]×[tex]4+\frac{x X4}{4} =65 X 4[/tex]
Reduce the fraction: x×4+x=65×4
Multiply the monomials: 4x+x=65×4
Combine like terms: 5x= 65×4
Calculate the product or quotient: 5x= 260
Divide both sides of the equation by the coefficient of variable: x = [tex]\frac{260}{5}[/tex]
Calculate the product or quotient: x = 52
get the result: x = 52
Answer: x = 52

Sully built a shelf 8 5/8 inches wide for his DVD collection. If each DVD is 3/8 inches
wide, how many can he fit on the new shelf?
Answer:
23
Step-by-step explanation:
8 5/8 = 69/8
Each DVD is 3/8 inches
Ignore the denominators
We have 69 and 3
69 is 23 times bigger than 3, so 23 DVD's can fit
