Answer:
At the end of the 1st year you have 21,000-0.14(21000)
= (1-0.14)21000 = 0.86(21,000)
So after three years you have 21000(0.86)(0.86)(0.86)
= 21000(0.86)^3
Answer:
3360
Step-by-step explanation:
Find 14% of 21,000 then multiply by six which gives you 17,640. Then you subtract 21,000-17640. that is your answer.

A poster is 1 3/5 feet wide and 3 1/8 feet long. What is the area of the poster?
Answer:
5 feet squared.
Step-by-step explanation:
You can multiply the length by the width to get the total area of the poster.
1 3/5 x 3 1/8 is equal to 5, therefore, the area of the poster is 5 feet squared.
Answer: 5 ft^2
Step-by-step explanation:
Area=length times width. In this problem, the lenght is 3 1/8 and the width is 1 3/5. We have to multiply these two:
1 3/5*3 1/8= 8/5*25/8=5.
So the area is 5 ft^2.

Answer:
1) Radius = 3yd Diameter = 6yd
2) Radius = 19ft Diameter = 38ft
3) Radius = 18in Diameter = 36in
Step-by-step explanation:
Diameter = r*2=d
Radius = d/2=r
1. Radius: 3yd
Diameter: 6yd
2. Radius: 19ft
Diameter: 38ft
3. Radius: 18
Diameter: 36
For next time the radius is half the diameter. If you want diameter it’s Rx2 and if you want radius you do D divided by 2
Write a verbal expression to represent the given equation,
X - 25 = 3
The graph of y = x2 –7x +12 is a parabola with x-intercepts at and a vertex that is the
point on the curve.
The vertex of the parabola is at the point (3.5, 0.75).
To find the x-intercepts of the given quadratic equation [tex]y = x^2 - 7x + 12,[/tex]we set y = 0 and solve for x.
[tex]0 = x^2 - 7x + 12[/tex]
Factoring the quadratic equation, we can rewrite it as:
0 = (x - 3)(x - 4)
Setting each factor equal to zero, we find the x-intercepts:
x - 3 = 0 => x = 3
x - 4 = 0 => x = 4
Therefore, the parabola represented by the equation [tex]y = x^2 - 7x + 12[/tex] has x-intercepts at x = 3 and x = 4.
To find the vertex of the parabola, we can use the formula:
x = -b / (2a)
In this case, a = 1 (coefficient of [tex]x^2[/tex]) and b = -7 (coefficient of x). Plugging these values into the formula, we get:
x = -(-7) / (2[tex]\times[/tex] 1)
x = 7 / 2
x = 3.5
To find the y-coordinate of the vertex, we substitute this value back into the original equation:
[tex]y = (3.5)^2 - 7(3.5) + 12[/tex]
y = 12.25 - 24.5 + 12
y = 0.75
Therefore, the vertex of the parabola is at the point (3.5, 0.75).
In summary, the graph of the equation [tex]y = x^2 - 7x + 12[/tex]is a parabola with x-intercepts at x = 3 and x = 4. The vertex of the parabola is located at the point (3.5, 0.75).

Answer:
D. 1.9 inches
Step-by-step explanation:
u did the butterfly method so just multiply across & divide so 95 • 9 = 855 and 450 • x = 450x
so 450x = 855
now isolate the variable so divide 450 on both sides
855 ÷ 450 = 1.9

-7.2x < -50.4x + 432
Answer:
x<10
Step-by-step explanation:
We can start off with adding 50.4x to both sides:
Once we do that we get the following: 43.2x < 432
If you notice, they both are almost the same number with the different of the decimal place. Lets multiply both sides by 10 to get rid of the decimal place:
432x < 4320
Now, if you see, they're basically the same number but the second place is x10 greater.
We can divide both sides by 432 and get x<10 as our answer!

Luis rents a 17-foot moving truck for 3 days. The rate for the truck is $60 for the
first day and $21.95 for each day after that. He also has to pay $0.79 per mile for
every mile over 50 miles. Luis also purchases insurance which cost him $20. If Luis
drives 200 miles before he returns the truck, how much will he pay?
$242.40
$204.35
$222.40
$281.90.
Answer:
Luis will pay $242.40
Step-by-step explanation:
60.00(1st day)+21.95(2nd day)+21.95(3rd day)+20.00(Insurance)=123.90
200 (mi driven) - 50 (mi allowed)= 150 miles must be paid for
150*0.79(rate per mile)=118.50
123.90+118.50=$242.40 Total Cost

Write the slope-intercept form of the equation for each line.
Step-by-step explanation:
First, let's find the slope of the line. Note that it passes through P1(-8, -1) and P2(0, -5). So the slope of this line is
[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-5 - (-1)}{0 - (-8)}[/tex]
[tex]\:\:\:\:\:= \dfrac{-4}{8} = -\dfrac{1}{2}[/tex]
The slope-intercept form of the equation can be written as
[tex]y = mx + b = -\frac{1}{2}x + b[/tex]
To solve for b, we can use either P1 or P2. Let's use P2.
[tex]-5 = -\frac{1}{2}(0) + b \Rightarrow b = -5[/tex]
Therefore, the slope-intercept form of the equation for the line is given by
[tex]y = -\frac{1}{2}x - 5[/tex]
