Answer:
5.1 years
Step-by-step explanation:
the formula for fixed rate depreciation is
Value after t years = initial value ( 1 - r )^t
where r = depreciation rate = 6.25% = 0.0625
t = length of time in years (we are asked to find this
Value after t years = given as $11,500
initial Value = given as $16,000
Substituting this into equation
11,500 = 16,000 (1 - 0.0625) ^t
11,500 = 16,000 (0.9375) ^t (divide both sides by 16,000 and rearrange)
0.9375^t = 11,500 / 16000
0.9375^t = 0.71875 (taking log of both sides)
t log 0.9375 = log 0.71875
t = log 0.71875 / log 0.9375 (use calculator)
t = 5.12
t = 5.1 years (nearest tenth)

(-4,5)
Step-by-step explanation:
(-4,5) is the solution.
what’s the value of x and what’s the angle?
Answer:
X=9 Angle= 55
Step-by-step explanation:
The sum of all the angles of a triangle is always 180
so we add the angles
50 + 75 + (5x + 10)=180
125 +5x+ 10=180
135 +5x = 180
5x= 45
x=9
to find the angle we substitute x for 9
5(9)+10=55

If a ramp has a slope of 1/10 what is the angle of elevation for the ramp
Answer:
What angle should a ramp be?
Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade). Minimum width should be 36" (inside rails) - (48" is ideal)

You ask 8 students how many letters are in their first name. One person says 6. The other 7 students say a different number of letters. Find the experimental probability of someone having 6 letters in their name based on this experiment.
Answer:
Step-by-step explanation:
Since only one out of eight said they had six letters
P(6)=1/8
The experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .
What is experimental probability ?Experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
We have,
Total number of students [tex]=8[/tex]
Person having [tex]6[/tex] letters in the name [tex]=1[/tex]
Other [tex]7[/tex] person says different number of letters.
So,
Experimental probability of someone having [tex]6[/tex] letters in their name is determined ;
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
[tex]=\frac{1}{6}[/tex]
So, Experimental probability of someone having [tex]6[/tex] letters in their name is [tex]\frac{1}{6}[/tex] , which is determined using the above given formula.
Hence, we can say that the experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .

Which of the following best describes the solution of the system of equations below?
Answer:
D
Step-by-step explanation:
-8x + y = -3..... (equ 1)
9x - y = 3.....(equ2)
y = 8x - 3
-y = -9x + 3(divide both sides by -1*)
hence ..y = 9x - 3
then write y = y in terms of x
which will give you 8x - 3 = 9x - 3
and solve for x which will be N/A
What is “f”
Thanks I really appreciate it
Answer:
19°
Step-by-step explanation:
19° + 24° + x = 180°
43° + x = 180°
x = 137°
24° + 137° + f = 180°
161° + f = 180°
f = 19°

Which Venn diagram shows the correct relationship among different sets of numbers and the correct placement of -648?
Answer:It’s A
Step-by-step explanation:
Which function is equivalent to y = 2(x – 4)^2 + 8?
A. y= 2x² + 24
B y=2x^2 – 16x + 40
C y= 2x^2 – 16x +48
D y=2x² – 8x + 24
Answer:
B: y = 2x² - 16x + 40
Step-by-step explanation:
You can find this simply by expanding the given function:
y = 2(x - 4)² + 8
y = 2(x² - 8x + 16) + 8
y = 2x² - 16x + 32 + 8
y = 2x² - 16x + 40

Answer:
y = 3/4x -7/4 or y = 0.75x -1.75
Step-by-step explanation:
The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points

What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
On a coordinate plane, the pre-image rectangle has points (0, 0), (6, 0), (6, -3), and (0, -3).
The image has points (0, 0), (2, 0), (2, -1), and (0, -1).
The required figure has been attached below which represents the dilation.
As we can see that the dilation is a reduction.
The point of dilation is about coordinate (0,0).
