Approximately how long will it take $200 to double to $400 when the annual interest rate is 8 1/2?
Answer:
200/17 years
Step-by-step explanation:
Simple interest = (principle * time * rate) / 100i
solve this linear equation into every single step you would use -x+9+3x=4x+2(x-3.5)
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
[tex]x+9+3x=4x+2(x-3.5)[/tex]
Distribute 2 to the parenthesis
[tex]x+9+3x=4x+2x-7[/tex]
Combine like terms
[tex]4x+9=6x-7[/tex]
Subtract 4x from both sides
[tex]4x+9=6x+-7[/tex]
[tex]-4x[/tex] [tex]-4x[/tex]
[tex]9=2x+-7[/tex]
[tex]2x+-7=9[/tex]
Add 7 to both sides
[tex]2x+-7=9[/tex]
[tex]+7[/tex] [tex]+7[/tex]
[tex]2x=16[/tex]
Divide both sides by 2
[tex]2x=16[/tex]
[tex]/2[/tex] [tex]/2[/tex]
[tex]x=8[/tex]

what is the equation, in point-slope form, of the ljne that is perpendicular to the given line and passes through the point (-4,-3)?
Answer:y+3=1/4(x+4)
Step-by-step explanation:
First find the slope of the line with the points -1,1 and 0,-3
1-(-3)/-1-0 = -4
perpendicular is negative reciprocal which is 1/4
now we have the slope, and a point so we can put it in point slope form
y+3=1/4(x+4)
point slope form is y-y1 = m(x-x1)
with x1,y1 being the point and m being the slope

What is the inequality shown?
Answer:
The inequality shown is 5.
Step-by-step explanation:
It's just asking for the inequality so you can basically just add the distance like 4 + 5 = 9.
whoch expression is equivalent to -20 - (-4)
Answer:
D
Step-by-step explanation:
-(-4)=+4
so it is -20+4
Answer:
D) -20 + 4 is the answer.
Step-by-step explanation:
1) Record the terms .
[tex]4 - 20[/tex]
2) Use this rule: a - b = -(b - a)
[tex] - (20 - 4)[/tex]
3) Use algorithm method.
(see the attached picture)
4) After simplifying, we have:
[tex] -(20 - 4) = - 16[/tex]
5) therefor, -20 + 4 = -16
[tex] - 16[/tex]
Match the solution set given in inequality notation with the solution set given in interval motion x > 7.8
Answer:
(7.8, ∞)
Step-by-step explanation:
Given the inequality :
x > 7.8 ; the inequality can be explicitly interpreted as x greater than 8 ; this means that the inequality holds for all values of x above 7.8
The interval for which the inequality holds true is :
x > 7. 8 - - - > (7.8, ∞)

Malik wanted to give away \frac{1}{5} 5 1 of his bag of balloons to his 3 friends. What fraction of balloons will he give away?
Answer:
The answer is 3/5
Step-by-step explanation:
The amount of balloon to be given away= 1/5
The number of friends to
receive the balloon = 3
Therefore the total fraction of balloons that he gave away = 1/5 × 3
=3/5
A pencil case with a cylinder shape with diameter= 10 cm
and height = 12 cm .
What is the length of the longest pencil that can fit in the pencil case?
Answer:
length of the longest pencil that can fit must be less than 13cm
Step-by-step explanation:
To get the longest pencil that fit the case, we will use the pythagoras theorem;
diameter = 10cm
radius = 10/2
radius = 5cm
Height = 12cm
Get the length of the longest side
l² = r²+h²
l² = 5²+12²
l² = 25 + 144
l² = 169
l = √169
l = 13cm
Hence the length of the longest pencil that can fit must be less than 13cm
given h (x)=5x-3 find the value of h(-4)
Answer:
h(- 4) = - 23
Step-by-step explanation:
To evaluate h(- 4) substitute x = - 4 into h(x) , that is
h(- 4) = 5(- 4) - 3 = - 20 - 3 = - 23
h (-3) = 57

4D+5P=$25
3D+4P=$26
Find the Value of D and P
Answer:
P= $29 and D = -$30
Step-by-step explanation:
4D + 5P = $25
5P = $25 - 4D
P = ($25 - 4D)/5 equation(i)
Noe substitute the value of P
3D + 4P = $26
3D + 4($25 -4D)/5 = $26
3D*5 + ($100 -16D)/5 =$26*5
15D + $100 - 16D =$130
-D = $130 - $100
D = -$30
Again substitute the vale of D in equation(i)
P = ($25 + 4D)/5
=$25 + 4*$30/5
=$25 + $120/5
=-$145/5
=$29
Answer:
P = 29, D = - 30
Step-by-step explanation:
Given the 2 equations
4D + 5P = 25 → (1)
3D + 4P = 26 → (2)
Multiplying (1) by 3 and (2) by - 4 and adding the result will eliminate D
12D + 15P = 75 → (3)
- 12D - 16P = - 104 → (4)
Add (3) and (4) term by term to eliminate D
0 - P = - 29
- P = - 29 ( multiply both sides by - 1 )
P = 29
Substitute P = 29 into either of the 2 equations and solve for D
Substituting into (1)
4D + 5(29) = 25
4D + 145 = 25 ( subtract 145 from both sides )
4D = - 120 ( divide both sides by 4 )
D = - 30

Answer:
(b) 36 in²
Step-by-step explanation:
The right triangle at lower right has a vertical leg of 3 and a hypotenuse of 5. Then the horizontal leg is ...
√(5² -3²) = √16 = 4
Then the horizontal diagonal is 4+4 = 8. The vertical diagonal is 6+3 = 9. The area is half the product of the diagonals, so is ...
A = 1/2(d1)(d2) = 1/2(8 in)(9 in) = 36 in²
__
You could figure the areas of the triangles separately, but you would come to the same result. This formula is good for a rhombus or a kite (or a square, which is also a rhombus), because the diagonals are perpendicular to each other.
During the carnival, tickets were sold for a raffle. Carnival workers counted sales every 30 minutes. The number of tickets sold were: 123, 145, 110, 256, 123. What was the median number of tickets sold?
Answer:
123
Step-by-step explanation:
First arrange in ascending or descending order
110,123,123,145,256
Then pick the number in the middle which is 123
but if you have 2 middle numbers add them together and divide by 2

Which polynomial below could produce this graph?
Answer:
f(x) = (x + 20)(x - 24)(x + 10)(x + 12)
Step-by-step explanation:
This is an equation of degree 4 and as the beginning of the graph descends from negative x the polynomial will have a positive leading coefficient. The graph is roughly W shaped.
It also has zeroes at x = -20,-12 ,-10 and x = 24.
So it is the first option.
The function f(x)= StartRoot negative x EndRoot is shown on the graph.
On a coordinate plane, an absolute value graph starts at (0, 0) and goes up and to the left through (negative 4, 2).

The domain and range of the graph are the same.
The range of the graph is all real numbers.

Explain how to solve 4x 2- 5x = 16 by completing the square. What are the solutions?
Answer:
[tex]x = \frac{16}{3} [/tex]
Step-by-step explanation:
Solve the equations:
[tex]4x \: 2 - 5x = 16[/tex]
Multiply the monomals:
[tex]8x - 5x = 16[/tex]
Combine like terms:
[tex]3x = 16[/tex]
Divide both sides of the equation by the coefficient of variable:
[tex]x = 16 \div 3[/tex]
Calculate:
[tex]x = \frac{16}{3} [/tex]

SOMEONE PLEASE HELP THIS IS DUE TOMROROW EZ WORK
PLEASE ANSWER THEM PROPERY FULL SENTENCES
Answer:
1.) At times, designing a good structure with a specific function may often be difficult. If the structure is not well-designed or strong enough for the function it will not properly work. So in order for the design to be well-built, both the structure and function must cooperate.
2.) Symmetry is a balanced arrangement on the opposite sides of a structure. In order for for a structure to be stable and properly work without complications, it most commonly needs to be symmetrical. This is a very important part of designing a structure.
3.) If the structure cannot withstand the function nor the possible forces that it may encounter. It is likely that it will break or even be completely destroyed.
4.) Shape, line, color, texture, movement, space. The designer may have taken into consideration whom the desk may be used by for the shape and space. Color, texture, and line may have been based on the environment (ex. A carpenter, student, computer desk) it would be in. Although the designer may not have an exact knowledge of where the desk would be, he still could consider what the desk could "possibly" be used for. Once again, the designer could take into consideration the user, for the movement of the desk. If the desk was to be moved around on wheels, or possibly could even fold. The designer must take into consideration EVERY detail.
6.) When people design something, often times you do not know how well that design is going to work without testing it with a prototype. Yes, prototypes are expensive. Yet, if they were to build something without testing their design, something may be wrong with it. So as a result, you will spend more money manufacturing something with a defect than testing it with a prototype.
For question 5, I think it might be best if you answer that one. It is based on YOUR opinion and what YOU use. If you are asked about it, they will know it's from you and your opinion. Lol! But I hope I helped you out with the other questions! ;)
