Answer:
Value of boat = $23,400
Loss of value by boat per year = 8%
To find: - Monthly percent decrease in value of boat.
Solution: - Decrease of value per year = 8% of $23,400 = $1,872. Monthly decrease in value = $1,872/12 = $156. Monthly percentage decrease = ($156/$23,400) * 100 = 0.6667 or 0.67 (rounded to nearest hundredth)

For each parallelogram below, find the value of x.
Will give brainliest for full answer
Answer:
x = 3 and x = 8
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, then
WA = DR , substitute values
12x - 9 = 5x + 12 ( subtract 5x from both sides )
7x - 9 = 12 ( add 9 to both sides )
7x = 21 ( divide both sides by 7 )
x = 3
------------------------------------------------------
The diagonals of a parallelogram bisect each other, then
QS = [tex]\frac{1}{2}[/tex] QT , that is
8x - 14 = [tex]\frac{1}{2}[/tex] × 100 = 50 ( add 14 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8
Answer:
x = 3 and x = 8

Answer:
a. -21
b. -16
c. -11
d. -9
Step-by-step explanation:
if x is less than -2, then u have to use the equation 5(x)-1
if x is greater than or equal to -2, then you have to use the equation (x)-9
Answer:
Step-by-step explanation:
This is a ‘piece wise function’ meaning it has different functions depending on the value of the independent variable, x.
So for questions a and b where x<-2 you sub the x value into the top equation, 5x-1.
f(-4)=5(-4)-1=-20-1=-21
f(-3)=5(-3)-1=-15-1=-16
Since the second two x values are not less than -2, you sub the x values into the second equation x-9
f(-2)=-2-9=-11
f(0)=-0-9=-9

Find how many years it takes for money to triple when invested at an annual interest rate of 4.3% compounded continuously. That’s the entire question and I’m not quite sure what to do?
9514 1404 393
Answer:
25.5 years
Step-by-step explanation:
The multiplier for continuous compounding at annual rate r for t years is ...
e^(rt)
You want the value of t when that is 3 and r=0.043.
3 = e^(0.043t)
ln(3) = 0.043t
t = ln(3)/0.043 ≈ 25.549 . . . . years

Step-by-step explanation:
A set of middle school student heights are normally distributed with a mean of 150 centimeters and a
standard deviation of 20 centimeters. Let X = the height of a randomly selected student from this set.
Find P(130 < x < 150).
You may round your answer to two decimal places.
Answer:
.34
Step-by-step explanation:
Khan
The required value of probability P(130< x < 150) is 0.34.
What is the Z -a score?
A Z-score is stated as the fractional model of data point to the mean using standard deviations.
here, z = x - μ / σ
where, μ = mean and σ = standard deviation
Here,
From the quesiton put value in z score formula,
z = 130 - 150 / 20
z = -1
P (z < - 1) = P(x<130) = 0.15866
P (x > 130) = 0.84134
Now,
P(130< x < 150) = 0.5 - P(x<130)
P(130< x < 150) = 0.5 - 0.15866 = 0.34134
Thus, the required value of P(130< x < 150) is 0.34.

Answer:
(-1.714, 1.857)
Step-by-step explanation:
Here, we want to find the approximate solution to the system of linear equations
We start by plotting the graph of the lines
We have the plot as shown below;
the red line represents the first equation while the blue line represents the second equation
We have the solution as the point at which the two lines meet

What is the image of 6, -7 after dilation by scale factor of 3 centered at the origin
Answer:
(18,−21)
Step-by-step explanation:
Dilation: multiply each coordinate
(x,y)\rightarrow (3x,3y)
(x,y)→(3x,3y)
Dilations multiply by scale factor
(\color{red}{6},\color{blue}{-7}) \rightarrow (3\cdot \color{red}{6},3\cdot \color{blue}{-7})=\mathbf{(18,-21)}

Right triangle XYZ is shown. Y (2,6) (1, 2) 6 х 7 Z Rounded to the nearest hundredth of a unit, what is the length of the hypotenuse?
PLEASE HELP ASK
Answer:
8.12
Step-by-step explanation:
We obtain the distance between x and y
d = sqrt[(x2 - x1)² + (y2 - y1)²]
d = sqrt[(1 - 2)² + (2 - 6)²]
d = sqrt[1 + 16)
d = sqrt(17)
d² = 17
From Pythagoras rule;
Hypotenus = sqrt(Adjacent² + opposite²)
Hence,
Hypotenus = sqrt(17 + 7²)
Hypotenus = sqrt(17+ 49)
Hypotenus = sqrt(66)
Hypotenus = 8.124
Hypotenus = 8.12

Explanation:
The value of k determines the slope, or rate of change, of how fast the balloon is climbing per second.
For example, if k = 5, then that means the balloon is going upward at 5 feet per second (equivalent to roughly 3.41 mph)
If k = 5, then y = kt becomes y = 5t. Note how we have the following
t = 0 leads to y = 0t = 1 leads to y = 5t = 2 leads to y = 10t = 3 leads to y = 15and so on. Each time t goes up by 1, d goes up by 5. This is one way to see how the speed is 5/1 = 5 ft per second.
