The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreciation, and t = time, in years. A car was purchased 6 years ago for $25,000. If the annual depreciation rate is 11%, which equation can be used to determine the approximate current value of the car?
Answer:
y=25,000(0.89)^6

Rachelle went for a bike ride for 2 hours and 8 minutes. If she finished at 4:35 p.m., what time did she start?
Answer:
2:27 PM.
Step-by-step explanation:
4:35 PM - 2hr 8 min
(35 - 8 = 27
4 - 2 = 2)The subtraction. It doesn't work like these 2 everytime.
= 2:27 PM.
Math help please!! Thanks in advance.
The third table is the answer.
x=-5 => y=-5-6=-11
x=-8 => y=--8-6=-14

HURRY 20 POINTS! Which ordered pair is a solution of the equation shown?
y=3/4x+1/2
Answer:
A
Step-by-step explanation:
3/4*(-4/3) + 1/2 = -1 + 1/2 = -1/2
First, B is not the answer, because if x = 0, the whole equation would've been 0.
A) -4/3 ; -1/2
Replace x and y with the 2 fractions, we have : 3/4 x (-4/3) + 1/2 = -1/2
-1 + 1/2 = -1/2 (true)
So, A is correct
But to make sure, we'll go over C and D also.
C) 4/3 ; 1/2
Replace x and y : 3/4 x 4/3 + 1/2 = 1/2
1 + 1/2 = 1/2 (not true)
So this is not the answer
D) 4 ; 3/2
Replace x and y : 3/4 x 4 + 1/2 = 3/2
3 + 1/2 = 3/2 (not true)
So, A is correct.

Suppose you are starting a new job and you are told there are two options you can choose from regarding how you are paid. Option 1: you earn $1 on the first day of your new job and double your previous amount each week for 6 months (so after the first week you get $2, after the second week you get $4, and so on....). Option 2: you can accept one total sum for $65,536. Which option would you choose? (P.S. Either way! want that job!). Hint: Use 2" = 65,536 where o represents the number of weeks you have to work to make the offered amount of money.
ILL MARK YOUR ANSWER AS BRAINLIEST IF U ANSWER
Answer: Picking the first option and constantly adding on and on you will eventually make way more than what the second option proposes, therefore picking the first option is the obvious choice.
Step-by-step explanation:
Well let’s see it starts off slow for instance 1, 2, 4, 8, 16 and so on adding that on for a month will eventually leave you with more.

Properties of equilateral triangles…………………….
Answer:
20.
Step-by-step explanation:
All sides and angles are the same length on equilateral triangles.
All sides will be 20u long and all angles will be 60° each.
3x—2
X+38
……………………………….
Answer:
x = 20; angles = 58°
Step-by-step explanation:
Since the given triangle is an isosceles triangle & the 2 opposite angles are equal, then even the opposite angles of the equal opposite sides will be equal.
So,
3x - 2 = x + 38
3x - x = 38 + 2
2x = 40
x = 40/2
x = 20
Angles:
■ 3x - 2
= 3(20) - 2
= 60 - 2
= 58°
■ x + 338
= 20 + 38
= 58°
=》Both the angles are equal & each measure 58°

A circular sprinkler system is installed and waters an area of 78.5 square yards. What is the radius of the circle? Draw a picture and show all your work.
Answer:
The radius of the circle is about 5
Step-by-step explanation:
The formula for the radius of the circle with a area is:
- R= the square root of the area divide by pi ( π)
or - R= the square root of A/ π
Plug in 78.5 into the formula
then you get the radius which is 5.
(you might need a calculator for this)
is 2:7 and 10,000:35,000 equivalent
[tex]Answer:[/tex]
No. They are not equivalent because sure, we can multiply them by 5,000 to get these 2 numbers, but 7 is not divisible by 5,000
Therefore, they are not equivalent ratios.

The circumference of a circle is 4pi. Find its radius, in feet.
Answer: 2
Step-by-step explanation:
The circumference of a circle is 2*radius*pi.
We can set up an equation as we know the circumference as 4pi.
4pi = 2*radius*pi
Divide both sides by pi:
4 = 2*radius
Divide both sides by 2:
radius = 2
Answer:
2 ft
Step-by-step explanation:
The equation for circumference is:
[tex]C=2\pi r[/tex]
We can plug in the given value for circumference to solve for the radius.
[tex]4\pi=2\pi r[/tex]
Divide both sides by 2π
[tex]\frac{4\pi}{2\pi}=r\\r=2\ ft[/tex]
Use the graph of the function y = 4x to answer the following questions.
The domain of the function is
✔ negative infinity
to
✔ positive infinity
because an exponent can be any real number.
The range of the function is
to
because 4x is always positive.
Answer:
the domain of y=4x is all real numbers.
Any number you can think that is not imaginary and certain transcendental numbers fall into the domain of y=4x

In a month of November, a dance troupe had 150 members
In December there was 20% decrease in the members
In January there was 20% increase from the month before
How many members were there in January?
Answer:
110 members
Step-by-step explanation:
Good luck!
Answer: 144
Step-by-step explanation:
so you find 20% of 150 which is 30 and because it is a decrease then you would do 150 minus 30 and that is 120. you would now find 20% of 120 and that is 24 so you do 120 plus 24 and that is 144.

Question: find the measure of the indicated angle in each triangle
answers:
A: 129
B: 360
C: 80
D:180
Answer:
Step-by-step explanation:
3 angles in a triangle always add up to be 180.
So, angle prq = 180 - 49 - 80 = 51
Angle qrx is supplementary to prq => angle qrx = 180 - 51 = 129

Answer:
B. 7√2
Step-by-step explanation:
One of the trigonometry formulas to find a missing side is:
sin θ = opp/hyp
Substituting those values in with the ones we have, we will get:
sin (45deg) = x/14
√2/2 = x/14
14(√2/2) = x
x = 7√2
